Get USB drives formatted in El Capitan to work in Windows 10

Posted on: November 14, 2015

Disk Utility in El Capitan.

El Capitan (Mac OS 10.11) rejiggered the stock Disk Utility programme to be more visually pleasing.

However, form no longer meets function because USB drives formatted in El Capitan may not be recognised in Windows 10 even if you use the exFAT file format.

I discovered this when trying to create thumb drives that worked across both operating systems. I had no trouble doing this in previous versions of Mac OS, only in El Capitan.

I discovered a solution from Reddit that worked for me.

  1. If open, quit Disk Utility
  2. Start the Terminal utility
  3. Run the following Command: defaults write advanced-image-options 1
  4. Relaunch Disk Utility
  5. Format your USB device with MBR Partition (Master Boot Record) and exFAT file system

The command in step 3 seems to activate a function that was previously on by default in previous versions. With Disk Utility put in this state, exFAT-formatted USB devices will now work with OSX and Windows.
