How to Check if Applications are Incompatible with Mac OS X Lion

Jul 15, 2011 - 20 Comments

Check OS X Lion Compatible Apps

You may know by now that OS X Lion drops Rosetta support, that means old PowerPC apps will no longer run in Mac OS X 10.7 Lion.

List What Installed Apps Are Incompatible with OS X 10.7 Lion

For incompatible applications, all you are looking for is the “PowerPC” designation, here’s the easiest way to get a list of these installed on your Mac:

  • Launch System Profiler (from Spotlight or hold down Option > Apple menu > System Profiler)
  • Look for the “Software” menu on the left side Contents list
  • Click on “Applications”
  • Click on “Kind” to sort your installed applications by architecture type, scroll through the list until you see “PowerPC”

Anything listed as “PowerPC” will not run in 10.7 Lion. Intel and Universal apps will run just fine.

If you are completely dependent on one of these PPC apps, you may want to try a dual boot OS X 10.6 and 10.7 configuration, or just skip upgrading to Lion until a Lion-compatible version of that app is made available.

If you look in System Profiler and none of your apps are listed as PowerPC, you should have no compatibility issues. You can view the broader Mac OS X Lion system requirements if you haven’t done so already, but aside from requiring a 64-bit processor they are fairly lenient.


Here’s an older screenshot of lots of PowerPC apps, if you see something like this and you use all of the apps, you would not want to upgrade to Lion without finding out if there are newer versions:

You can also check to see if actively running apps are PowerPC by using Activity Monitor.

    I think the only app that is causing a problem is Quicken, Intuit needs to step it up and release a new version for Mac users.

      Jackie mentioned below iBank which does have a 30 day free trial. I tried it and did not like it. I moved to Quicken Essentials.

      Essentials has gotten a great deal of criticism for removing features which made me hesitate to switch to it. However, when I finally tried it, I liked it alot! I think the interface is far better than Quicken 2007 was. It’s exactly what I need for me personal finance tracking.

      I don’t know what features were removed – I obviously didn’t use them. But if you’re someone who is more of a Quicken “power user”, then maybe it won’t be the right choice. But, I’d drop into the Apple Store and see if you can’t take it for a test run. :)

    Interestingly, most of my “PowerPC” programs are various Adobe CS5 scripts and a couple of python scripts. I’m not sure how a script can need Rosetta although it being Adobe, I wouldn’t put it past them.

    Unfortunately, there are some old utility programs that I use frequently (CubicConverter comes to mind) that are PowerPC. I doubt they will get upgraded and I will have to either find a replacement or just not deal with Lion. That isn’t such a big deal, Snow Leopard works fine.

    Mine says “No information found” under Applications tab
    any thoughts on that?

    • Mike says:

      Make sure indexing is turned on in Spotlight. I had mine shutoff with Cocktail and had the same result. Once I turned it back on, Spotlight did it’s indexing and all the apps showed up.

    I also find a number of “Classic” applications on my Intel Mac Mini (Nov. 2009) now running OS 10.6.8. Delete them?

    Likewise, several duplicates to delete.

    I presume “Universal” should be fine in Lion.

  5. Jackie says:

    iBank 4.2.4 has proven to be a wonderful replacement for Quicken for Mac 2007. Excellent import integrity from Quicken for Mac 2007. I find iBank to be a polished, ready for prime time product that will address the needs of many former Quicken fir Mac 2007 users.

    I need to confirm, I have Quick Book Pro 2007 and it is listed as an “Universal” so it will continue to work?
