A Macbook user just raised an issue with me regarding they can't plug in a USB drive to ttransfer files.
I do know we have a restriction profile that stops iCloud, imessage. I don't know we had a restriction on USB connectivity.
If it a setting in JSS, where would I find this (and disable it)? We're using JSS 9.81.
If you plug a USB mouse into his Mac, does it work? Does the drive mount on another machine?
USB ports are managed by an extension file - /System/Library/Extensions/IOUSBMassStorageClass.kext
If it has been deleted, then the USB ports will be disabled.
There is a Configuration Profile that can disable external Hard Drives.
