Mac OS X 10.7 Lion System Requirements

Mac OS X 10.7 Lion System Requirements

Update: Mac OS X Lion has been released!. You can download OS X Lion from the Mac App Store Now for $29.99 right now.

We’re all excited for Mac OS X Lion. We know it’s only $30 but a single purchase will cover installing on all of your Macs. We know it will be released in July through the Mac App Store. But up until now, we didn’t know the hardware requirements. Now we do.

Mac OS X Lion System Requirements

In order to install Mac OS X 10.7 you will need:

  • Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
  • 2GB of RAM
  • Mac OS X 10.6.6 or later with the Mac App Store installed
  • At least 4GB of additional disk space to accommodate the download, but more is obviously recommended

That’s it. The hardware requirements are surprisingly basic, but that’s good news. Apple’s own Lion web site even touts a simple three step process to install the update once it becomes available: check Mac compatibility, update to the latest Snow Leopard, and download Lion from the App Store.

What about upgrading from OS X 10.5 Leopard directly to Mac OS X 10.7 Lion?
If you meet the hardware aspects of the Lion system requirements, then you’ll most likely need to upgrade first to 10.6 prior to 10.7, simply because 10.6.6 is the release that the Mac App Store was included with. Lion requires the App Store to install from, and thus the 10.6.6 requirement to install. If you’re in this situation, Snow Leopard is $29 with free shipping from Amazon.

Core 2 Duo is NOT the same as Core Duo
This is important to point out: the Core 2 Duo chip is newer and fully supported by Mac OS X Lion. In fact, any Mac bought within the last 5 years should have the Core 2 Duo CPU and will be fully supported. The names are similar, but the chipset is fundamentally different, with the Core Duo being an old Pentium-M based 32 bit processor and the Core 2 Duo being a completely different 64 bit architecture. Blame the confusing naming on Intel.

What about Core Duo & Core Solo Macs?
You’ll notice Core Duo & Core Solo CPU’s are not officially supported. The Core Duo & Solo chipset made a brief appearance on a series of Macs released between 2006 and early 2007, so any Mac newer than 2007 should be good to go. The other news about the older CPU’s is that users have hacked Lion Developer Builds to work on those chips, so you can bet someone will do the same for the final Lion release too. That said, there’s probably a good reason Apple has chosen not to support the Core Duo and Core Solo CPU.

    The reason Lion doesn’t support Core Duo and Core Solo is because Lion OS is 64-bit and Apple wants all their devs to build 64-bit ONLY applications. The processors are capable in terms of load, but 32-bit architecture is really quite old. An OS demanding a 5 year or newer machine is not too extreme.

    • Thomas jensen says:

  2. Simon Williams says:

    Surely, after lion install, you get a chance to burn off an install DVD. If my Hard Drive fails, I dont want to have to install a new one, install Snow Leopard, and then install Lion from the App Store.
    If there is a rescue partition that Lion creates, thats all well and good, but leave the door open for viruses and malware to install on the partition, and then reinstall themselves after a clean install, meaning the only way to get rid of them would be to completely wipe everything and start over…not sold on this app store only thing at all.

  3. Sam says:

    I’m still curious if there is a way to do a clean install with Lion. Its kind of a deal breaker for me if I have to clean install Snow Leopard and then upgrade to Lion.

    • PsychoX says:

      It’a deal breaker for me to have to purchase Snow Leopard before I can even hope to upgrade to Lion.

      • Dan says:

        Why? You can’t install Windows 7 from Windows 95, what’s the difference here?

        Look at it another way, the combined price of Snow Leopard and Lion is still $100 cheaper than a Windows 7 basic upgrade. Plus you get an unlimited personal license with Apple now. How can you beat this? Really, I think it is quite generous, but I am a tad frustrated on the lack of DVD sales.

        • PsychoX says:

          Not planning to use Windows 7 anyway, so the point is moot. For those of on a budget (which is why I am not running Snow Leopard just yet it) it’s more of an expense that cannot be afforded to buy both.

          • Doug Petrosky says:

            Then stay where you are. Apple could have shipped Lion on DVD for $129 single user or $179 for 5 user license and you would have been worse off. If you have a lion capable mac and have been waiting over 2 years to figure out how to scrape up $29, what on earth makes you think any of us believe that you would have upgraded to Lion? And if this is about the money, go find any friend with a copy of Snow Leopard and use his upgrade copy.

            Seriously! Apple priced these upgrades to encourage EVERYONE to take advantage of them. Are you really trying to tell me that all of the advantages Apple has included in the OS from Leopard to Lion are not worth $60? And remember this is $60 for all of your systems, not just one.

            Besides, It is likely that you will be able to boot from the Lion disk image so as long as you can get it downloaded from ANY computer using your Apple ID. You will be able to boot from it and clean install on a bare drive let alone leopard.

          • hmdwigg says:

            Budgets I totally get… but the Snow Leopard upgrade is $30 and the combined SL to Lion upgrade will be $60, still about $70 less than what a single user Leopard upgrade and all previous OS’s cost. And, as Dan notes, it’s available for all your Mac’s no more “Family Pack” at $179 (though that was a good deal at the time too.)

          • PsychoX says:

            @Doug Petrovsky:You know when one only makes 200 dollars to 800 dollars and has many other things they need to pay for and living on a month to month basis, 60 dollars is really hard to come by. As for the friend thing, I don’t have any friends that are running Macs. The only other people I know that have computers are my family, and they are all running Windows based PCs. As for your suggestion that I am attempting to tell you that the upgrade is not worth it, nowhere in any of my previous posts was I attempting to imply such, so please don’t try to make inferences about what it is I am trying to convey. All I was simply saying is that, as a low income individual on a strict budget, it’s really difficult to be able to afford such.

        • Roger says:

          I have to agree with Dan on this one, no matter how you slice it, Lion is a good financial value whether you already have Snow Leopard or not, and Apple’s decision to give Snow Leopard owners a discount on Lion (by making SL required thus jacking up the price of the Lion experience) was even smarter.

          In this day and age of Windows OS costing anywhere from $100 to several hundred dollars, none of us have room to complain about an extra $29 for Snow Leopard.

          In closing…as a registered developer beta testing Lion, I’ve found it to be very snappy and responsive with more features and improvements than I expected. So far I’ve been more than pleased with the OS, including its upcoming price tag. :)

          • JCrebbin says:

            You can install Lion onto a non-Leopard installation – it requires you to erase the HDD first. While Apple would prefer you to upgrade from SL, and pay the associated costs, it also has to provide Lion as an installer that can be used when a HDD fails and a blank HDD is used.

            The installer deletes itself after executing.

            After completely downloading, but not yet ‘ok’ing’ installing, copy the Installer application (in applications) off to another location.

            There are instructions on the web about creating a bootable installer from this application (you need to Restore to a USB drive a DMG within the installer).

        • Brian says:

          “Why? You can’t install Windows 7 from Windows 95, what’s the difference here?”

          10.5 to 10.7 is more like upgrading Windows XP 32bit to Windows 7 64 bit. Except that with Windows its possible. Throwing Windows 95 into this conversation is like talking about upgrading OS 8 to Lion… Stupid comparison.

          “Blame the confusing naming on Intel.”

          Really? Core Duo and Core 2 Duo is confusing? I guess if you can’t tell the difference between Core and Core 2 then maybe you should have to pay a $30 tax for being less than smart.

    @Peter

    The only problem there is Apple makes such good hardware, it runs forever.

    • irecinius says:

      You mean INTEL right? Apple made powerpcs…. now we using same technology as PCS… intel.. core2duo, i7’s etc.. since they are vastly superior

  5. NoJoke says:

    If there is a way to install on a core duo, I will do so. It’s rediciolous: I can install windows 7 on my MacBook, but not run 10.7 Lion? I will not do a favour to Apple and buy a new MacBook just because his Steveness thinks, to use a Apple product for 5 years is long enough. And what comes next? OS X 10.09 LYNX runs on ARM-Chips only? Let us look in the future: The last core2duo Macs where sold in 2010/11. So the end for Intel based Chips comes 2016. The AppStore thing makes it more difficult to get a hacked LION for average hardware. Maybe I’m going to become a switcher again: from windows XP to 10.3 and over 10.6 und back to windows 7. It is so sad.

    • hackintosh says:

      someone will modify it to work on 32 bit architecture, don’t worry. The hackintosh crowd does this stuff all the time.

      :)

    • Carl says:

      Buying a new Macbook is not a favour to Apple they are a business; when you buy a new Macbook that’s great for them, and you, actually – but favour? That’s the problem here, people who are complaining about spending a few dollars on a brand new OS are thinking that Apple are their friends and should look after them because they bought a Mac once. They’re a business, and a much more user friendly business than Microsoft at that. If you can’t afford 29 dollars on some new software, you really can’t afford life, and certainly can’t afford computers, or electricity or coffee! As for buying a new machine, listen, if your Mac can’t run the latest OS then don’t upgrade to it! If they were to only release software that ran on EVERYTHING then we wouldn’t progress. The people who do have the more modern hardware wouldn’t experience its capabilities because there are those who want to hang onto their Powerbook G4 or whatever it is. Stop ruining it for everybody; as for switching from Mac to PC – yeah, good luck with that.

      • Amen says:

        Well Said

      • CDN says:

        Macs are essentially PCs now anyways. They both use the same processor, same chipset, etc. Why is it though, I can’t install OS X (legally) on my PC? Because Apple would be put out of business. Why buy a Mac with it’s overinflated price when you could buy a much cheaper PC with the exact same specs? I can run Windows on my Mac, so I should be able to run Mac OS on my PC.

        As for saying that “If you can’t afford 29 dollars on some new software, you really can’t afford life, and certainly can’t afford computers, or electricity or coffee!”, not spending the $29 on an OS is HOW he can afford these other things. Stop being so high and mighty and realize that not everyone is as well off as you.

      • Jason says:

        Yeah I also agree with Carl. You can’t take your windows based pc from 8 years ago and stick Windows 7 on it, so that’s the issue here. A new OS will need bigger badder hardware if you can’t afford it live with what you have and be happy with it.

        • Brian says:

          Where does an 8 year old machine come into this? Core Duo MacBook Pro and iMac was released in January 2006 which means the OLDEST a Core Duo computer could possibly be is 6 years old.

          And my 8 year old PC is running Windows 7 just fine, thank you.

      • dmartin says:

        I think you are missing the point. People are not complaining about spending the $29 on a new OS. People are complaining about having to buy a whole new computer, when their current computer works just fine. If you have a core duo processor, like I do, I will no longer be able to sync everything from my mac to my iphone. This has become a must with my work. The cloud will not work, mobile me is a thing of the past. If you have a 5 year old computer that works perfectly fine, you will not be able to use the new Icloud, because you can not download Lion. This stinks! The fear is that every 5 years they are going to force us to buy new computers, not by building crappy computers (because they won’t do that), but by changing the operating systems to the point that we have to upgrade.

  6. ER Joker says:

    What happens if I try to install it on my 2007 iMac running the newest version of Snow Leopard and an Intel Core 2 Duo, but only 1GB of RAM.

    • Matt says:

      It would probably install but not run that great. You really should upgrade your RAM, upgrades to 4GB and 8GB are very cheap and make for a significant performance boost.

      • ER Joker says:

        All right, thanks. Any suggestions? I’m not really familiar with getting memory upgrades and I don’t want to get something not compatible.

    • gkappledev says:

      Sorry Darryl,
      No you wont. You need a Core 2 Duo (you have a Core Duo) and you need at least 2 GB (you only have 1 GB).

          • Brian says:

            Hackintosh IS illegal in that it violates the EULA that Apple/Mac attaches to its OS. It clearly states that the OS is for use on Mac hardware ONLY. A Mac clone builder, hackintosh retailer, what ever you want to call them, Psystar, just recently lost all of its court cases against Apple/Mac pertaining to exactly this issue and have been forced to cease all Mac compatible related retailing.

    • huh says:

      Why does everyone ask the same question? Doesn’t anyone read specs anymore? :/

      • Brian says:

        Because most Mac users eyes glaze over and they get lost reading the hardware requirements… they can’t tell the difference between Core and Core 2, its all gibberish to them. Most Mac users want to be babied by Apple and have everything to stupid simple that they have no clue what’s actually inside the machine. They want a car but don’t have any idea that the engine has air filters, spark plugs, sometimes even gas! (OMG my Mac shut down! — well plug it in stupid!)

  20. Alan Day says:

    I work and live in South Africa. Download bandwidth here is not like that of the USA. Typically a small business like mine has 2 to 3 Gigs available for the WHOLE
    MONTH! So there is no way EVER that we will be making a 4 gig download. Apple (probably run by greedy accountants) are obviously cutting more corners again – first Less manuals – smaller manuals – NO manuals – now no install disk!! Also my 8 core so called “64 bit workstation” as it says on the box – is Version 2.1 – 32 bit firmware. No Lion. It doesn’t matter how cheap it is if it’s WORTHLESS does it?

    • Keo says:

      I don’t know how you can say Apple is probably run by “greedy accountants” considering they are reducing the cost of a new OS to $29.99? I remember when Apple released OS X Leopard & it cost $129.99. If anything Apple are making the cost of a new OS more affordable by making it download only, cutting the cost of packaging ect! But hey, if you seriously want to pay $129.99 for new OS, when Apple are offering a fully fledged new one for just $29.99 good luck!

      The fact that you have a poxy Internet connection is not Apples problem, I mean what are they supposed to do… go round to every Mac users house & upgrade their Internet connection for free?

      • casper says:

        No! Just make a DVD available to those who need it for one reason or another! Not everyone who wants to do business with Apple has a fast, uncapped, reliable Internet connection. This shouldn’t be a system requirement for a computer, or an operating system.

  21. Jim Bob says:

    my thought on the whole thing is Apple will release a DVD version. Releasing on the App Store first will boost sales for the quarter. No company is above cooking the books to some extent. I find it very hard to believe Apple wont ever release a full version DVD of Lion

    Also keep in mind upgrades are optional the frameworks still stays the same and 64 bit only applications are still awhile away simply because software developers don’t want to pigeonhole themselves either

  22. Assaf says:

    Hi folks
    Any advice please?

    I have a MacBook, bought in June 2007, 2GHz Core 2 Duo, 1G RAM, Currently running 10.4.11.
    I believe the MacBook can be upgraded to 2G RAM, right?

    I’ve never wanted to upgrade the OS because of the ‘if it ain’t broke don’t fix it’ policy. I fear discovering all sorts of compatibility and stability issues and that the computer ‘is just never what it was since I upgraded’.

    But I just got an iPhone4 and it complained it can’t sync with iTunes 9. So I guess this means I do finally need to upgrade. Well ok, let’s go for it – i’m looking forward to all the features I’ve been missing out on.

    But my question is: To which version do you suggest I upgrade, given that I’m not so technically savvy and really don’t want to risk getting the troublesome issues I mentioned.

    Shall I, can I take it to Snow Leopard? Or maybe just a modest Leopard and no further? Or if I can upgrade the RAM, then should I go for Lion, or leave Lion for now till it matures?

    Many thanks
    Assaf

    • Matt says:

      I would go with Snow Leopard if you are concerned about application compatibility, you may still be using older Rosetta apps which wouldn’t work in Lion. You’ll definitely want to upgrade to 2GB of RAM as well. Once you’re on Snow Leopard it will be easy to upgrade to Lion, if you decide to do that too.

  23. Assaf says:

    So given that Snow’s been around for a while now, then you’re suggesting that there’s no need to be worried about compatibility issues and things stopping working. Or at least if they do then it should just be a case of upgrading them too. Is that fair go say?

    Thanks again

    • OSXDaily says:

      Any apps that are Rosetta based (PPC architecture) won’t work, but other apps should work. To take advantage of some Lion features like full-screen mode and Versions, developers will need to update their apps.

      • Assaf says:

        OK, great.

        So maybe I could ask a couple more questions. But if this is not really the right forum, then feel free to point me to a ‘How To’ page or the right Forum. Thanks a lot.

        In fact, I’m likely to have many questions during this process, so could someone point me to an appropriate forum please?

        So…

        Can I download the files I need for installation or need I go to a shop or Amazon to buy the installation discs?

        I’m having trouble identifying what I need to buy, as some sites seem to suggest (though it’s not clear) that I can do both a clean install or a Tiger to Snow leap using the $29 Snow Leopard installation disks. Is that correct?

        Would you folks recommend a clean install? It sounds good, and I’m pretty sure I can identify and back up all my data so I’m not too worried about wiping the disc if the clean install is indeed possible, recommended and trouble free-ish.

        I can’t find Apple’s page on the Snow Leopard system requirements etc; it’s all Lion now… of course. Can someone perhaps direct me?

        Do you recommend I increase the RAM from 1G?

        And what about my measly 80G hard drive which is about 70G full, (mostly with itunes stuff which I believe can’t be spread across multiple locations, right?)? Is there a utility that will help me slim the drive down?

        I have to be honest, the thought of upgrading my OS give me the heebie geebies. It’s so common for things to go kaput. A quick search shows people experiencing lots of trouble in the past when upgrading from Tiger to Leopard. But, I’ll give it a go.

        enough said.
        Thanks for your responses,

        • Dennis says:

          As far as itunes goes, i have a mybook 1TB network edition and have my itunes library set to run off the network. This task is pretty easy to move your library from your internal drive to the network drive, and point itunes to use the new location. Not sure if it would help but its definitely an option. Also on that note be sure to check from time to time that the location of your itunes library doesn’t default back to the internal location as it has a tendency to do so from time to time.

      You may have seen mentions of “Hackintosh” – this means installing OS X on non-Apple hardware. I have not done it myself, but others I know have done so. If you like tweaking OS X to run on hardware that may not be the best fit, go for it. I’d prefer to just get a Mac and leave the hacking to others.

    Well, I’ve purposely NOT upgraded to Snow Leopard because I’ve been waiting for Lion. (Didn’t want to have to do it twice.) Now I find I HAVE to upgrade to Snow Leopard before I can get Lion. Question. My daughter has Snow Leopard on her Macbook, can I upgrade my MacBook (to Snow Leopard) from hers (no DVD’s/CD’s came with it)? How do I know if any of my apps are PPC versions? Anything else that I may have not going to work with Lion?

      Can I ask where you purchased you daughters Macbook as I purchased a Macbook Pro late 2009 which came with Snow Leopard boot dvd + utilities dvd. Seems strange your daughters didn’t!

      Anyway, after checking with a guy at my local Apple store if I could use my copy of Snow Leopard to upgrade my iMac which has Leopard installed, I was told that the copy of the OS on both the machine & the discs are usually tied in with the serial number of the machine. However he did say that if you search on the internet, there may be a work around or hack to enable you to use it on another machine!

      Perhaps if you tried creating a bootable disc from you daughters Macbook & burning it to dvd, you could get it to work!

      Give it a try!

    It says dual core and not dual 2 core but has core i7. does that mean I can upgrade to Lion???

    Right On Doug… All this griping and complaining!!! Whaaa! Good Lord, man-up and pay for something!!! These babies would complain if it was free! They probably buy Goober Grape for their sandwiches too… ain’t gonna open TWO jars! And think of all the silverware they’d be using. Years ago, I paid the big bucks for stupid Windows upgrades. So, THANK YOU APPLE! The world’s greatest operating system on the world’s greatest computer…It doesn’t get any better than this!!! Pay up, ya pajama wearing, Wal-Mart goon!

  36. galanti says:

    I’m annoyed that Lion won’t be available on 400K floppies so I can install it on my 512 Fat Mac. OK, so the computer is 26 years old, but that’s no excuse for Apple leaving me out there twisting slowly in the breeze.

      Note you have a mid2007 MacBook.

      Though you can put 4GB of RAM in to the laptop, the machine only has access to 3GB of the RAM.

      So… with a 2GB minimum, that gives you another GB to utilize easily for programs. Word/Email/iTunes/Browser could likely easily fit in that memory space. Some of the bigger beasts, like Aperture will struggle.

      It’ll work though.

    • M says:

      Yes, you have a brand new Mac, it is definitely compatible with OS X Lion and may qualify for a free upgrade. You should contact Apple and find out!

  45. James Grigato says:

    Yeah but doesn’t the OS X Lion updated Software only work on MacBook Air? Because I have a MacBook Pro and not the MacBook Air.

    Pls. help! My husband bought MBP version 10.5.8 august 7, 2011… and only now did we realize, after thinking of switching to lion, that we we’re running only the leopard version and not the snow leopard… we thought all along that we had the snow leopard since it was released so close the date of our purchase. Anyway, does anybody here knows if we can still avail free upgrade of our mac os from leopard to snow leopard? I do hope we can still avail. Pls advise. Thanks a lot!

    I have a ’09 MacBook with 8 gigs of RAM and a core 2 duo processor – Lion was impossible to use. It ate all my cpu which caused it to run burning hot (180F), lock up – sometimes indefinitely, slowed Safari to a crawl. I had to back down to Snow Leopard, now everything runs fine. So yes you can run Lion on a core 2 duo but I promise you, you don’t want to. The features are nice but not so nice that I want to wait all day to do simple tasks.

    Linux works on the early intel mac mini. I put ubuntu 12.04 lts on one, the 1.83 ghz model, and it works great and will be supported to 2017, and its free. And then I can upgrade to the next and next, indefinitely.
