It does somewhere.
Welcome to the land of the third world internet.
I saw that the file was almost 5G so I went to the
UMC @ CU Boulder to download. Took no time at all.
Are you near an internet backbone facility with public access?
Find one and use it for large files.

I recently received a mac book pro from a friend of mine. I decided to clean install OS X mountain lion to make sure there was no left over stuff from the files she had on it. Now when i turn the computer it give me the option of re-installing the software;
I click continue and it says contact apple
Am i able to make OS X flash drive installer without the mac? (My other computer is windows)
Thanks a million

Hi,

I may have a few silly questions but here goes:
I’ve never performed a clean install before, and am running mountain lion at this moment. I want a clean install because my mac is a little slow..it’s a pro from 2009 – and I just feel it is time. also I’m sure there’s a ton of stuff on it I don’t need – that I’m unaware is draining my mac.

Just wanted to ask (as someone who’s never clean installed before)
1. when I back up do I just copy applications folder, docs and anything I know I want to keep?
2. or will the timemachine back – up be enough? Will that be the easiest way?

I’m getting a 3TB external hard drive, so I figure that will be enough.
Also I have a few games on there Sims 3 – tomb raider and the likes – also sims midieval which I downloaded from online store. If I coply applications or use timemachine,will I be able to recover this after the clean install?
If I follow the above instructions to a T…will I be in good hands? There is no way I can mess it up?

Thanks so much

Two questions.
1. What will happen to my Boot camp partition after a clean install of Mac OS X? Will I still be able to boot windows normally?

2. What happens to programs that requires license to install, for example Office 2011, Photoshop CS5 etc? Will they allow me to restore it from TimeMachine backup or do I need new licenses?

Ben,

Long answer so google for each program.
I just copied the correct folders for iTunes, Mail, iPhoto etc. and placed them in the exact spot. Mail was the trickiest.

After doing a clean install what’s the best and easiest method for putting my old files, photo’s, music and app’s back onto my Macbook Pro from my external Hard drive

You can’t erase the disc from where the disk utikity is located (if you are booting from the recovery you wont be able to do it because the recovery partition resides on the same disk). You had to create a separate startup disk (can be DVD, pen drive or just an external HD) startup from it and erase the internal HD.

Well I highly recommend a clean install – I bought a MacBook Pro 2011 with snow Leopard, upgraded to Lion, then to ML. Running pretty sluggish, so did a clean install – its like having a new mac!!!! Did take 6-7 hours to reinstall everything though

try running disk utility first, and make sure there’s a Mac formatted partition on the drive. It could be completely blank.

I just install an additional SSD hard drive into my late 2007 Mac. I wanted to put a new copy of MAC OSX lion but my DVD player was set to a wrong region, USB drives wouldn’t work so I decided to download it from Mac.

Before I did that I partitioned the drive and then shut down the computer and then held command R untill I could download from the Apple store. Then I downloaded and it restarted but it wouldn’t install. I restarted it a few times but nothing.

So then I tried to reset the PRAM by holding down command, option and P and R. This chimed twice and I let it start up. Then I was still not installing.

I then tried command R one more time and then it started to install. Seems to be the only and no one else talks about. I even read that someone said that it cannot be done without a bootable USB.

Sorry for the correction, The apps which u have purchased from Mac App Store which is tied to your apple id will still be available the ‘Purchased’ sections for u to redownload and install again. I’ve tried several times…
