Write access to FAT32 USB drive blocked under macOS Monterey
I want to share a USB drive between a Windows computer and my Mac.
Everything I read says that my Mac should be able to read/write to FAT32 or ExtFAT USB drives, but I can't write to them.
I've tried the suggested fixes:
- Change the permissions
- Reformat the drive on my Mac
- Use DiskUtility First Aid to check and fix the drive
but none of them work. I can read the drive but I can't write to it.
I've tried a number of USB drives but I get the same problem.
Here's a FAT16 drive. The permissions say: "You can only read", and there is no option to change this:
Here's a FAT32 drive. The permissions say: "You can only read", and there is no option to change this:
I even tried a NTFS drive formatted on a Windows computer on the basis that I might be able to install the drivers on my Mac to write to NTFS. But it doesn't look very promising. This time, it shows the permissions:
But even when I click unlock and try to change these, I get a message saying that I don't have permission to change this!
I do have admin access to my Mac - it's the only user on the Mac - so it doesn't make sense.
It also doesn't make sense that my user's permission says: "Read & Write", but above it there still a message saying: "You can only read".
It's like there is something overriding all of the permissions. I'm wondering whether it is some feature in Monterey. I'm running version 12.6:
Does anyone have any suggestions?
