I work as the one-person "IT Department" for a small but growing wildlife conservation non-profit based in San Francisco. I find myself figuring out a lot of things through my own research, trial and error. This is my attempt to give back to the Non-Profit IT community.
Format disks using ExFAT with GUID partition map to use on both Mac and Windows
If you want a disk so that it works with both Mac and Windows, format as ExFAT and use the GUID partition map. NTFS won't work on the Mac (current Macs can read, but not write), and Mac formats won't work at all on Windows.
