• Can someone help me get my brain straight please.

    Currently have: Mid 2010 Core2Duo MBP. 256GB HD and want to switch out for SSD.
    Since new (Snow leopard I think?) It has had OSs installed over the top of each other, so I imagine a clean install of Yosemite would be beneficial. Is it as simple as using a SATA -> USB cable to install Yosemite on a new SSD drive, swapping them over, and then using the cable to attach the old drive and dragging files etc that I want to keep back? What about apps/games? If I create a backup on an external HDD then restore from that will I get the benefit of the clean install or will it literally just duplicate my current drive? Also, I've read something about trim controllers (or something) and SSDs on Yosemite. Is this a pitfall I need to be aware of?

    Essentially what I'm looking for is sage advice on the most effective/efficient way to make the swap. I currently don't have an external drive, so hoping to avoid springing for one of those as well as a new SSD.

  • I did this to an old white macbook, all happy now:

    • put SSD in USB caddy and install OS onto it from laptop.
    • Boot into newly installed OS to check all is well, then access internal HDD to drag over files I want to keep.
    • Swap drives inside laptop
    • Install apps from fresh
    • Keep old HDD for a while as a failsafe.

    I have a Time Machine backup but I never restore from it as I always assume it'll put all the crap back on too. I often keep a copy of the ~/Library folder, just in case there are some pref files that I want to keep later on.
