I can't write to my USB on MacBook Pro. The USB was working well on both Windows and Mac until it stopped working on Mac suddenly (it's working well on Windows though). I reformatted it as FAT32 and tried other formats too (ExFAT,...etc) but, still facing the same issue.
Under "sharing and permissions", I find "you can only read" and it is greyed out so, I can't change it.
Any ideas are welcomed as I've been stuck in this since more than 2 weeks.
