I'm considering buying a new MacBook Pro after today's refresh, and I am wondering if OS X handles simply pulling a drive out of one MacBook Pro and putting it in another. I know that in the Windows world this is — most of the time — possible, but I have never tried it with OS X. Does the OS handle the sudden change in hardware, or does it 'sh*t bricks' and abort mission? In theory you'd think it could handle it, but anyone with definite experience would be good.

Odds are, the new drive is larger than the old, no? Certainly younger, and harddrives have a failure rate that rises with age. I suggest you use migration assistant and just move the data over to the new machine.

In general, this is a very safe, OS X boots other hardware in general situation.

However, when new hardware is released - often a special build is made and until the next revision or two of software, you can't boot that hardware so you'd need to take a hard drive from the specialized machine to an older one instead of the other way around.

It's far safer to migrate from a Time Machine or target mode or from running OS using file sharing / network. That way each machine has the correct OS and can flag apps or system files for non-transfer when there is a known problem migrating them.
