Macbook Pro HDD & OS upgrade - advice request!

post #1 of 5
Thread Starter 
I have an early 2011 MBP (i7, 8GB RAM)

I have a 256GB Samsung 830 SSD that I'm planning on replacing the stock drive with, and I also want to upgrade to Mountain Lion at the same time. I know I should do a clean install on the new drive.. but I really don't want to have to resetup everything! So I'm planning on cloning the drive..

My main question is about the order - should I clone the drive, install the SSD, then upgrade to ML? Or upgrade the OS first, then clone and change out the HDD? Or will it not matter either way? I thought maybe the upgrade process would tidy up anything that might be messed up by the cloning process..

I am assuming the cloning thing will work ok - planning on using CCC.. stock drive is 500GB but only 105GB in use..

Any advice by more experienced Mac people appreciated!

Hi!

If I were you I'd just make a time machine copy from your current setup, then change out the disk and do a clean install of Mountain Lion. At the end of the setup it'll ask you if you want to restore from Time Machine. Select yes, select your backup and the things you want to restore, wait for it to finish and you're done.

I've done this on multiple machines, including my macbook pro (from lion to ML) and an older iMac (up from Snow Leopard). No problems what so ever. smile.gif


But I guess if you really want to, the cloning way should work about as good. I'd say the order doesn't really matter. The only thing that could get messed up are file permissions, which you can easily repair in Disk Utility. I'd do this in between every step to make sure everything goes as smooth as can be.

So, for example:

Repair disk permissions -> clone disk -> swap drives and restore clone -> repair permissions -> upgrade -> repair permissions -> done.

I do like the idea of a clean install better - does Time Machine restore everything? Apps, preferences etc? What about emails within Thunderbird?

Appreciate the help! +rep thumb.gif

Well I finally got around to doing this today, with great success! Thanks Radeon915 - your suggested method worked well!

What I did:
- Used Time Machine to back up system on external drive
- Downloaded Mountain Lion and created USB installation drive
- Swapped out HDD for Samsung SSD
- Booted with USB drive inserted and installed Mountain Lion
- Restored apps, files and settings from external drive using Time Machine

And I was back! The only issue I ran into was with a fan control app which didn't restore properly - had to quickly reinstall as one fan wasn't running at all and the CPU temp was getting high! Reinstalled app and all good though.

Optimisations I performed:
- Installed Trim Enabler to get trim running as I found OSX doesn't like doing this for non-Apple SSDs!
- Disabled hibernation
- Deleted sleep image file (freed up 8GB)
- Disabled local Time Machine snapshots
- Disabled sudden motion sensor
- Disabled hard drive sleep settings

Pretty rapt with the results so far - if I've missed anything that anyone knows of that I should've done then please let me know!
