The only real downside to this solution is that exFAT's relative newness compared to FAT32 will make it incompatible with certain less popular hardware, although it was still released in 2006, so this is increasingly inapplicable. You can convert the FAT32 flash drive or external drive that you're having trouble with to exFAT, which is a newer, more superior filesystem with file limits that are so large they can (currently) be considered non-existent. Convert your flash or external drive to exFAT Until Apple eventually releases the update that fixes it, there are two workarounds for this bug. It has, however, been reported in that last MacRumors thread by myself and at least one another user, so it will hopefully be added to that list soon.
This particular bug is the latest in a long list of bugs introduced by High Sierra, and is apparently so minor/rare relative to others that it hasn't registered on any of these non-comprehensive lists of them. Thanks to SpiderPig for finding conclusive evidence that this is a bug in MacOS High Sierra - namely, this Reddit thread created within the past few days, which has a few users attesting to it.įor additional context, I thought I'd add the results of my research since asking this question.
