Just installed this onto my macbook 3,1 with SNow leopard. It crashes, refuses to even open.

2.2.2 still crashing

Version 2.2 had worked worked on my system (Mac Pro tower OS X 10.9.5) until recently, but recently the app crashes any time I try to select another target drive. Works fine on startup disk. So, installed 2.2.2. Works fine on startup disk, but immediately crashes when attempting to select another target disk.

Wow… great… thanks!

I had a few older external hard drives that I wanted to connect to my brand new iMac 27” Retina 5k running OS X El Capitan. I didn’t want to slow down my system by connecting some older technology but didn’t know how to go about testing the drives. So I googled my question, and found this little puppy. After downloading version 2.2.2 and running the read/write tests, I realized my older Seagate external drive was still pretty fast while my Iomega was dreadfully slow… so, dumpster for that one. Thanks BlackMagic! (This is not an infomercial nor am I in any way associated with the company that distributes this product… I’m just just a happy customer.) By the way, it took only seconds to download and launch. And it’s free... How good is that!
