Use CSV to work with JAMF Quickly change iPad name Quickly change username (using preload) Quickly put JAMF + apple classroom to work After Wipe Device, apple classroom still work without attention. Please manually add the user "__noUser_byJamming" on JAMF before using extension. The effect is that this account will be brought in when there is no username setting on the iPad (limitation of preload).
