How to Make an Exter­nal Hard Dri­ve Work With Mac OS – Guide

An external hard drive compatible with Windows and Mac operating systems can be very useful for users working on both operating systems. However, Windows is mainly optimized for the NTFS (new technology file system) format, APFS is made for Mac OS. As we all know, NTFS is not compatible with the Mac and APFS cannot handle Windows either. Fortunately, with the help of this article, you can create an external hard drive compatible with Windows and Mac OS.

This does not require any third party applications or additional software help. Let’s start making the external hard drive compatible with the Mac.

Why you need to reformat the external hard drive

When I bought the hard drive for the first time, I was unable to copy anything to it (but I was able to copy it). Disk Utility showed that it was formatted for MS-DOS (FAT), but I’m pretty sure it would be NTFS. If you have the same problem, your only recourse is to reformat it in one of two formats. Like my WD My Passport Ultra, most external hard drives are customized to work with Windows, not OS X.

If you are going to use the external hard drive with Macs only or want to use it for Time Machine backups, format it in Mac OS Extended (Journaled). If you are like me, who also needs to use at least part of the hard disk of Windows PCs, you will need to choose the MS-DOS (FAT) format. But here you won’t have a lot of support for Time Machine. In addition, you cannot create partitions larger than 2 TB or move files larger than 4 GB.

How to Reformat the external hard drive

  • First, connect the external hard drive, bring up Spotlight Search using the Cmd + Space keyboard shortcut and type in Disk Utility. Press Enter and Disk Utility will start. You can also find it in the Utilities folder under Applications.
  • Now, in the left column, select 1 TB WD My Passport (or whatever the name of your hard drive is) and click the Erase tab.
  • From here, under Format, select Mac OS Extended (Journaled), give it a name if you wish and click Delete.
  • You will receive a warning. Again, click Delete.
  • In a few seconds, you will have a hard drive ready for OS X available.

    How to Create Partitions

    I am planning to use my hard drive for Time Machine backups and to transport media files. I may need to use the hard drive with Windows computers, so I will format one of the partitions as MS-DOS (FAT), fully aware of its limitations. The other, for Time Machine backups, will be in Mac OS Extended (Journaled) format.

  • To create a partition, select the hard drive in the left column and click the Partition tab.
  • From the drop-down menu under Partition layout, select the number of partitions you want. Don’t overdo it here.
  • Now, just below, you will see a visual representation of the partitions. You can use the breakpoint to resize partitions by moving them up or down. You can also click on a partition, name it and select the format.
  • After deciding all the details, just click on the Apply button button. From the popup, select Partition.
