I tried other products considered less professional that showed better performance (by far) in Yosemite with macbook pro. In operation, nothing wrong that's okay. By cons, to switch the machine on and off: absolutely no difference from a conventional hard drive. It therefore remains very slow when other models offered a marked improvement (by starting much older MacBook: 2007 in two seconds).
I am also a little disappointed with the price. Disappointed that regularly Amazon inflates the prices of its products just before we buy them as soon as one comes to show interest in one or the other product. And then the price returns to normal after the purchase. I still had the case here: HDD paid 225 euros, returned immediately after receipt of the product at 205 euros. I begin to find it strange.
Moreover, the site is still reliable in terms of time, product ordered and received in the same week. Nothing to say on sending everything is consistent and well packaged.
Everything is easy to install, just provide a copy of Mac OS X and the two screwdriver needed. All the rest is a breeze. Watch in hand, I put the machine on foot in less than an hour (assembly, disassembly, installation, catering, all inclusive: short we see that uses a SSD and installation is easy and accessible to all).
