Hi all,

If you use an external drive on MacOS, please be aware that even the latest MacOS versions have bad support for file systems like Fat32 and NTFS.

NTFS will only work, if you purchase additional software from the Mac Store to support read and write on a NTFS file system. I use Paragon's Microsoft NTFS for MAC :

Fat32 will just not work robustly with big integrations and is not advised due to the low file size limit in this partition type. If you would use it, strange and bad things could occur with your integrations, so be warned 😉 Here is one example:

Fat32 banding big integration due to file size limitation

2 options luckily remain,

  1. if you need to use the external drive with Windows / Linux computers: use the ExFat file system on your external drive, it should work without issues and it can handle huge files !
  2. If you don't need to use the external drive with Windows/Linux computers: simply use a MacOS file system for the best and most robust performance.


Kind regards,

Thanks for the tips Mabula! I wasn’t aware of the ExFat file system.

As a matter of fact, it is possible to use an external disk with a Mac file system on Linux. The only requirement is to disable the journalling of the Mac file system. Once that is done the disk can safely be mounted on Linux in rw mode and changes can be made. I have been using my external disks like that for over a year now with no issues whatsoever.

Not sure if this works on Windows because I don’t use that OS.
