Formatted APFS in Mojave shows file format in system report as MS-DOS just fitted an ssd to my Mac Pro 5.1 Mojave enabled, working ok but when I looked at the system report it says the file system is ms-dos, is this a problem? the only option I had for formatting the ssd in disk utility was APFS which I chose



Thanks Ted
Everything is fine as the EFI volume is supposed to be formatted MS-DOS FAT32, and as you can see your disk0s2 volume is as should be Apple_APFS.
