This is 3 TB model, and it's working perfectly in both Windows and Mac upon respective formatting after partitioning. This actually works for me although the product might say its specifically for Mac journal.WD came in good shape and could easily be reformatted for specialized Mac or Windows file systems using standard operating system utilities. The prebuilt software is helpful to configure and start using the drive. Its also convenient to setup Mac timemachine backups to this device at ease.This is not heavy though and just a little thicker than some of the lower capacity USB powered drives I have used, but is still incredibly compact say 3X4 inches or so. The plastic drive case is smooth, and probably won't crush in or break. Data IO speeds are great as promised.

Avoid this brand. All of my files are gone.

All of my files are gone. I'm talking wedding photos, newborn photos, first birthdays, everything. This is inexcusable. I am at complete loss of words. To put your faith in a company with something so priceless, and the only option is: "a replacement device". The native utility app did not fix the problem nor identify the issue. I want them to pay for the files to be recovered. I will continue to post this unless there is some tangible resolution in sight. Contact me.

BACK UP, BACK UP, BACK UP

I'm 72 yrs old and a still-active newsstand magazine publisher, freelance web designer, and pro photographer and videographer. Trust this: In terms of computers and drives, I've seen and been through it all. I've been using external drives large and portable since the late 1980s, my first being SeatGate, then La iCe (the worst0, and many others. I cannot tell you how angry I was when I lost hundreds of precious family photos that can NEVER be replaced on that SeaGate. I swore I'd never use them again, and I haven't, or those 8 La Cie's I got from the Apple Store (still sitting in a back room for the last 30 years, awaiting the day I can get to them and have the data and photos recovered, if possible).

I cannot tell you how angry I was when I lost hundreds of precious family photos that can NEVER be replaced on that SeaGate. I swore I'd never use them again, and I haven't, or those 8 La Cie's I got from the Apple Store (still sitting in a back room for the last 30 years, awaiting the day I can get to them and have the data and photos recovered, if possible). I learned one thing critical to all drives: Back Up, Back Up, Back Up. There is no workaround to that. Here's what you may not know and sellers sure as heck don't tell you: Expect your drive (any drive) to last 2-3 yrs, if you're lucky. Maybe 4. Next, if it is, say, a 1-TB drive, if you load it with over 70-75%, it can cause your drive to malfunction at the loss of all your data. And this may not occur immediately. To avoid total loss of your data, ALWAYS buy 2 identical drives so you have everything backed up as I do, especially my precious family photos. Here's what I did 6 years ago when I started with Western Digital. Every week (or right then and there) I would load my latest information and data onto my newly purchased drives (Drive A) and back it all up onto the second drive (Drive B). Every 6 months I would buy 2 new drives (C & D) and put personal and family photos from drives A and B onto the new drives (C & D). Note: I keep all business data and projects on separate drives. To accommodate the growing size of my data/photos, I increase the size of my drives as I need them. With WD, I've gone from their 1TB to now their 5TB portable drives (BTW, the "...for Mac" models are no different, no matter what they tell you, than the significantly cheaper ones used for PCs, you just have to reformat them which is easily done) to store my personal stuff. I also back up ALL this unto two large (18 TB) G-Force desktop drives. So, the lesson here is that ALL drives fail, usually much sooner than later with typically no more than a few years of longevity. Whether a month old or 5 years old, they can go out on you for any number of reasons, including bumping or dropping them or smacking them down on your table unless they are SSDs, but even they can die on you too. If you're backed up to another drive, you're good. If you haven't done that, you're....well, you know. They can also die on you for no apparent reason at all even if you've handle and treated them like a newborn baby. And remember, you can be working on a report, term paper or thesis, website, editing photos, whatever, and have backed up two days earlier. Although you'll be safe with all that back-up date on the second drive, you'll have lost all the stuff you've been working on for the last 2 days that you hadn't backed up if your computer goes out! BACK UP every 30 minutes or so if you're working on very critical "ABSOLUTELY CAN'T LOSE THIS STUFF) data, photos, web projects, etc.). My 27-inch Mac Pro is sitting at a computer repair shop as I write this. The video card went out while I was working on a complex website design project and I hadn't backed up that day yet. Fortunately, the loss of the video card didn't cause the los of my work on the computer. But my work over the last few days is sitting in folders on that computers and I need to continue working. So, I'm taking a brand new Western Digital 5-TB portable drive over to them now to put all my folders sitting on my desktop onto that drive and I'll back up all that to a second drive and continue working but on my laptop. REMEMBER, always buy 2 drives, NOT one. And, to Western Digital's credit, since I started using their products 6 years ago, only a big external drive died on me. I have 16 (8 plus their back ups) of their portable drives and ALL of them still work, even the first two I purchased over 6 years ago. Forgive the length of my message but I hope it will help anyone buying external drives for the first time and remind others what you already know. Back Up, Back Up, Back Up. Western Digital cannot replace the data you lost (don't throw away those drives, have the data recovered by a trusted, professional data recovery service) but you can prevent losing your data and precious memories by BACKING UP your data and buying 2 new external drives every 6 months and transfer data from the old drives to the new ones and keep the olds ones (with their data) too.

Disappointed

I've been using this product for at least 20+ years and never had a problem. My current 2 passports were full so I purchased two new ones today. When I plugged into my USB port and opened Time Machine, I couldn't back up unless erasing what was on the disk, which is the software. I've just spent 3 hours on the phone being transferred and disconnected and waiting on line with Apple and then Best Buy. These came with no instructions and when I googled, it said they should plug in and go. I've had my last two passports for 7 years. Have your products gone downhill?

Don't buy this. Mine broke within one year

Inexpensive, and that is about it. I put all my hours of work onto this external hard drive My passport for Mac, and one day it started clicking. Now i am told that all the data is lost. Thousands of hours of my work is gone, or now i have to pay another $800 to get the information back. Don't buy this product. The only thing their support offers you is a new passport. So you are out thousands of hours, and they lose about $15. Sound fair?

Full disclosure: I bought this to use with a Windows machine (other models were out of stock) rather than a Mac. Aside from the "for Mac" branding on the box and back of the case I think it is exactly the same physical product as the "regular" My Passport drive. Good news if you want to use this one with another OS or would like to use the non-Mac one with a Mac. There's also apparently some bundled software on the drive which was obviously for Mac in this case. I'm not interested regardless of what OS I'm running so I just ran a CLEAN command in DISKPART (this is Windows remember) then repartitioned and finally did a full format. The full format took about 14.5 hours to complete (5 TB model). No problems. The full format may not be necessary but I always like to ... MoreFull disclosure: I bought this to use with a Windows machine (other models were out of stock) rather than a Mac.

The full format took about 14.5 hours to complete (5 TB model). No problems. The full format may not be necessary but I always like to run that on a new magnetic drive. I bought three of these to use in rotational backup scheme. Only been using them a short time but so far they seem really solid and well built and have operated flawlessly with no signs of trouble. I think the full format, and my initial syncing and subsequent verification of 1 TB of existing data provided a nice little up-front stress test. There is one big issue I didn't realize coming into this and I likely would not have bought the My Passport (Mac or not; since it's the same for the Windows formatted one) had I understood it before purchase. All of these My Passport drives include built-in hardware level encryption which at face value sounds like a good thing. However, this encryption is always-on even if you aren't using it. So, while the disk appears plain-text to the OS the underlying sectors are all encrypted on the disk. As long as the drive is functioning normally this has no real practical implication since plain-text goes in and plain-text comes out. However, in the event you ever need to send this device for data recovery it will complicate the process, increase the cost and time necessary and honestly probably greatly increases the odds that nothing could be recovered. This is unwelcome for my purposes since my rotational backup scheme involves rotating two encrypted drives (using software drive-based encryption through the OS i.e. Bitlocker) off-site and keeping one on-site non-encrypted in a physically secure location. This is a problem for me because the plain-text copy is a last line of defense in a major disaster recovery and I'd want a data recovery specialist to be able to recover the data from the drive if it ever came to that. I know how to secure my own data and I don't need WD forcing some encryption on me I don't want and didn't ask for.

Great for storing files

This review is for WD 2T My Passport™ for Mac. I have been a long time Macbook Pro user and this portable external hard drive is extremely great for backing up all the important files in my laptop. I do most of my work using my Macbook so this is important to me incase something happens to my computer. It works great with Time machine. It is easy to use like any external hard drive. I like that my files are safe in this hard drive because it is encrypted and secured with password protection. This external hard drive is well built. It is portable so I can easily take it anywhere with me. Great product and must have for backing up important datas.

Unmounted while doing backup, now undetectable

I have been happy with my passport for mac 5gb since I got it in february as it was fast and perfect for a tiome machine, so I thought. So, I have 2 external HD just to make sure I am safe in case the other one stops working or I get robbed. I bought this one on amazon from the US to deliver to Indonesia as the procucts I have been buying here have not been working. Anyway, a few days ago I did a backup to my old disk, a WD too but older, then when that was done I unplugged the old one and plugged the new one. All was going well and I could see it was copying the files but at a certain point, about 1 minute before finished it started to really slow down until it unmounted by itself and could not complete the task. I tried again and again to remount it but could not. ... MoreI have been happy with my passport for mac 5gb since I got it in february as it was fast and perfect for a tiome machine, so I thought.

I have changed cables and tried with other disks and everything works well except this one.Anything I can do to fix? I have gone through everything and it is just not being seen by the computer, as if there was nothing there

Works great for Time Machine backups!

I have been using Western Electric for years, so I was excited to try this new drive out. I needed a portable backup for my MAC and this was perfect. I connected this up and had Time Machine running on this in no time!Pros:Very compact and portable (a little bit taller than a standard deck of cards, but thinner), easy enough to fit into your pocketCompletely quiet, I have never heard a noise from the drive since using itWorks seamlessly with Apple’s Time MachineThe drive is very light-weight and dependableCons:The cable they provide has an adapter to switch from usb to usb-c vs using just a having a standard usb-c ended cable.Has no rubber feet to keep it from moving aroundOverall this is a great product and I would highly recommend this to anyone!

Worst Experience

I bought this product in March of this year and it has already crashed. Every time I attempted to connect the external hard drive to any computer or mac, it would not populate and it would force eject with no notice. This happened from the beginning. Furthermore, when the hard drive was fully corrupted, there was no way to access a single ounce of my date. I took it to a store to fix it, but they were unable to do so because the passport hard drive is made so that you use a specific wirings that require extra cost and longer wait time. I had this information reinforced at numerous stores. Will now be pushing people towards other hard drives after this.
