I received a WD My Book 4TB USB 3.0 Desktop Hard Drive WDBBGB0040HBK-NESN Black and have a 27" iMac (late 2015) with Mojave 10.14.3. I now see that there is a My Book for Mac. Will the one i purchased work on my machine or do I have to return and re order one specifically for Mac? Not tech informed and will appreciate any help. Thanks
Yes, you can use the WD My Book on your iMac with Mojave 10.14.3. The WD My Book comes formatted for Windows operating system and requires reformatting for Mac operating systems.
