Rating: 5/5 Just Installed August 28, 2015 I just installed the Seagate HDD/SSD drive on an old MacBook 2009 unibody. Like they say, took 10 minutes to install. I did not remove the battery. I did wear nitrile gloves. Works great! If it quits, I'll update. I put the old drive in the enclosure.

I did duplicate the old drive to the new drive using the restore process (holding command and R at start up). First, I put the new drive in the provided enclosure, connected to the computer, and then restarted, selecting my old drive as the boot drive. Then, using Disk Utility, I "restored" the old drive to the new drive. That took about 7 to 8 hours (about 480 GB data).

When I installed the new drive- the old one had been duplicated to it, so I didn't have to "restore" the MacOs- just started right up.

I'm sure the more mac literate already know this, but I had never done this. The instructional video - all of five minutes, was all I needed to install the new drive.

Rating: 5/5 Restored an old macbook August 1, 2015 I picked up an old Macbook because I needed a computer to run older software that would not run on an OS later than 10.5. The OWC upgrade kit was easy to install and turned this $100.00 bargain into a little workhorse that runs nearly as fast as my MacBook Pro. There was such an improvement that I purchased a kit for my 2009 iMac as well.

Rating: 5/5 An easy & worthwhile upgrade! August 23, 2014 My White Macbook was slowing down, the hardrive almost full. Rather than retire it, I thought I'd try an upgrade. I'm glad I did! The video instructions and tool kit make it easy to install. The Hybrid drive is quite fast and with the RAM upgrade it seems like a new machine! I have plenty of room now with a 1tb drive and a nice portable external drive as well!
