I chose this drive based on the reliability of the Hitachi hard drive used in this product. It's ready to go with Mac Time Machine and the speed has been excellent. More information on why you should consider this (and other G-Technology hard drives) can be found here: [...]

Great choice for Mac upgrades. I bought this to upgrade my MacMini (late 2012) and it runs really fast. Previously, the MacMini took about 1-2min to start up with the original HDD (those are 5200RPM). Now, it makes about 10 seconds to start up (counting since you hit the power button until you can actually use the Mac).

Plugged it in, turned on Time Machine, and had my Macbook backed up in under an hour. It even came out the packaging nicely.  It worked so well, I'm going to rebox it and let my 3 year old try it out.

I bought this drive back in dec 2013 for my MacBook Pro early 2011.
This hard drive has been working awesome with no issues at all . The speed is decent but of course is not like SSD.
I recommend you do a clean install of IOS after installing the hard drive .
If you use time machine all your library  issues and permissions will transfer to the new drive and you might not notice a difference in the speed .
Again it's a great drive ..

I bought this to put into a 2008 20" iMac. The original 500GB drive had really started to slow down, and the move to 10.10 was finally just too much for the old drive. Anything I wanted to do resulted in a wait while the drive tried to access files. Super speed isn't really of the essence in a replacement drive for such an old machine since the speed of the bus is slower than almost any newer SATA SSD, and I didn't want to spend too much considering its age. I put this in, and I'm amazed at how much faster the system is (though the clean install of the OS probably had something to do with it too). If you are looking at this to try to restore some zip to an older machine, I can whole heartedly recommend the BX100.

Seamlessly integrates with Time Machine on the Mac. Easy to use. Nice small size. Tme machine reminds you to hook it back up occasionally.

I bought this during a Black Friday special. I wanted to use the hard drive specifically with my MacBook Pro with Retina Display. I take a lot of photographs so I needed an external drive to keep a back up of all my files. When I received the item I was disappointed to see that it listed only support for Windows. I plugged in the drive and it was instantly recognized by my MacBook. I was able to partition the hard drive into two partitions. I used the first partition to be used with Time Machine and the second to be used for file storage. Seems to work flawlessly. It has a decent size and weight to it but I tend to like feeling the weight of a product within reason at least. I guess it makes it feel more legitimate vs. cheap. It could be used as a portable hard drive but for my use it'll stay at home. Overall I'm very happy with my purchase and glad that the hard drive prices are starting to go down since the Japanese hard drive shortages.

Tip: The file format you want to use for your Time Machine partition (backup) is Mac OS Extended (Journaled). Also if you're interested in using your external hard drive on Mac and PC use "exFAT" as the file format.

Great product. Works great with my MacBook and Mac OS X Leopard's Time Machine. Easy setup: no manual needed. Love the Firewire cable included. I only have two USB ports, so the firewire cable is quite handy (there's a USB cable in the box, as well).

The WD Passport for Mac 1TB was easy to setup and coordinate with the Mac's Time Machine. I have not had to recover saved data to reinstall on my computer so I can not comment on that function of the hard drive. It is small, lightweight and sleek.

Great little drive. Using with 1TB SSD MacBook Pro Retina as my Time Machine drive. I hook it up about once a week via Thunderbolt. Routinely copies 500MB-3GB within just a few minutes (mostly music, photos, docs, Parallels Desktop backup).  I'm not disappointed that it is not an SSD drive - it's more than fast enough not to annoy me, and I like things fast. Have had it for several months now with no issue.

Put this on my 2009 iMac w a dying HD, downloaded El Capitan OS onto it and then used Migration Assistant (in Utilities) to move things over. There were a few bad moments as the old HD acted up but I got it done in time. Yes, yes, would've been easier if I'd have been backing up w Time Machine like I should've... But now it runs far, far faster than even new, best $230 I ever spent on tech stuff!

Setup as EHD on my MacBook Pro in minutes and is working in conjunction with Time Machine software like a charm.

This is the second or third Seagate brand portable external device I've owned and used for my Mac without any problems. It works quickly and plays fine with "Time Machine". It works quickly (faster than older generation externals I've used) and is quiet and small. These things get better and better every time! I love it!

This is unquestionably the best drive for easy backups with Mac OS X 10.5.  Time machine instantly recognizes it and file transfer is very quick with FireWire 800 on my new MacBook Pro 13-inch. Highly recommended.

Purchased this for my Macbook Pro to use for TimeMachine backups.  It works perfectly and is actually pretty fast.  I have two drives in my laptop and this external drive backs them both up with plenty of reserve space.  The drive is quiet and operates off of a single USB 3 cable and requires no additional power source.  So far so good!

Bought this drive to use with Time Capsule, was easy to connect too and has been doing backups on a MacBook Pro w/Retina 15". Connect it at the end of day and did its thing as it was supposed to do with Time Machine. Can't get any better than that.

I hooked this up to my Time Machine on my Apple Mac and it worked fine right from the start.  Love the color.  This is my 3rd Toshiba external hard drive, and I never had a problem with the other 2 older Toshiba drives that I used before this one.  The other 2 still work fine, but I have them secured with saved data and I no longer use them for now.
