The DJI Copilot comes pre-formatted in the exFAT file system. Both Macs and PC’s can read and write to exFAT file systems, so you are able to use the drive between your Mac and PC.
The recommended format for your DJI Copilot is the exFAT file system. While it may work if it is formatted into a different file system, you may see issues as the device was not tested in these environments. The drive will no longer be interchangeable between Mac and PC if the drive is reformatted into a file system other than exFAT.
