Mac - Convert from Case-Sensitive to Case-Insensitive File System

So I just got my first Mac. After getting everything set up just the way I wanted it I decided to install Steam. When I opened Steam it said something about not supporting case-sensitive file systems...

I did some googling and found that Steam won't be the only application that gives me this trouble. Photoshop (when I eventually install it) doesn't support case-sensitive file systems either. I'm sure there are other applications as well.

There is at least a work around for Steam, but it involves disc images and symbolic links. Not very fun. It works, but it's not very fun (and Steam is supposed to be all about fun, no?). I am not aware of any work arounds for Photoshop.

So here's my question. Can I boot into the disk utility, format the drive to be case-insensitive, and then restore from time machine? Are there any technical limitations that would prevent me from doing this? I haven't named anything like Folder 1 and folder 1 yet, so I am not aware of any collisions that would show up.

Solution 1:

It looks like you can restore from time machine to a case-insensitive file system from a case-sensitive one. See Apple Forums here.

I would highly recommend that you perform a total system backup using Carbon Copy Cloner.

Carbon Copy Cloner does support restoring to a case-insensitive system from a case-sensitive one - see this.

In fact, I would recommend CCC over TM, but you should use what you feel comfortable with. I would also boot to the CCC image and make sure all my stuff was there before I wiped my internal drive and did the restore. CCC makes a bootable back up (which is another reason it's awesome).

Solution 2:

I haven't used it, but iPartition claims to be able to do nondestructive conversion between case-sensitive and case-insensitive HFS+.
