Question: Is this compatible with Yosemite OSX-13" MacBook Pro 2011 Baseline model?
Document: I have only had this for a couple of months, so can't comment on longevity, but I can say that it paired nicely with a MacBook Pro 13 running Mavericks.
For some reason, it had some connectivity issues out of the box - my macbook pro 13&#34; just wouldn't recognize it, or it would appear for brief moments and disappear. However, when I finally got it connected and went through the setup/installations, it worked perfectly and still is as of now. It's cheap and functional.
In a silver-toned case that matches the MacBook Pro, the 500GB My Passport for Mac (Western Data) works well and is compatible to the Mac OS. Better: The utilities available on it are for maintenance, and security: Superb and even with others on the laptop, made for the drive. It's a plastic case, so lightweight, but a plastic case, so feels a bit toyish.
Bought this to back-up my new MacBook Pro 13 w/Retina. I plugged it in the USB slot, the computer recognized it right away and the back up started. Could that be any easier. No software to install. I use this and the 1TB Airport Time-Capsule, for alternate back-ups. I had a 300MB WD My Passport I used to back up by 2009 MacBook Pro 15&#34; and it never failed.
I just purchased a new MacBook Pro Retina Display 13&#34; with a 256 gb SSD and knew I wanted to keep all of my media (i.e. videos, photos, music, etc.) on an external hard drive since the solid state drive isn't very large. I initially purchased the WD My Book 2 TB which is not made for Mac specifically but is supposed to be easily reformatted. Well, it turns out it wasn't that easy.
I was able to load my photos and videos - very easy to use with my MacBook (late 2008 model).
Very stylish and good shape,but it doesn't work with my mac everytime i connect it,i think you need USB 3 in your mac or purchase a separate USB 2 connector,by the way my mac pro is 2011 so its not too old.
Hey MAC folksFYI you have to jump through a lot of hoops to make this compatible with a MAC. WISH I had known this before. I am sure some super computer literate person could figure it out quickly but I am at least an hour in and still cannot work on my Macbook. Have to reformat the drive etc etc which is featured on Page 55 of the manual.Annoying.Reformatting the DriveCAUTION! Reformatting the drive erases all its contents.
Got this as a gift for my boyfriend. He uses it with his time machine on his iMac and MacBook Pro. He was very happy with it.
So far, so good. It's really easy to use my my MacBook Pro. No set up required, which is always good.
Answer: Yes. I have been using it and it works fine. It appears to backup my MacBook Pro fine. I have not had to restore the backups so i haven't test that. Although I have viewed the  folders on the backup drive.
