iTunes backup encryption password
Hi,
I've just connected my iPad mini 4 to my MacBook to try and backup the iPad to iTunes. iTunes still thinks my very old backup is has a password? I know you usually can't recover a backup without the password, but I thought that would be if you weren't using all new devices? The MacBook has never been used for an iTunes backup and the iPad mini 4 has never been backed up to a computer. The backup would've been from about 10yrs ago with devices I don't even have anymore. I've tried all the old passwords I can think of and none work. I thought that it would let me start a new backup if its the first time the device is being backed up?
Please help.
I don't want to never be able to back up a device to a computer for the rest of my life.
