Trying to sync new iPad with iMac OS Monterey. Doesn't work.
I bought a new iPad from Argos almost a year ago but did not have time to set it up until now. I have an iMac OS Monterey 12.7 and want to be able to copy some files from this computer to the iPad. But I have not yet been able to activate the iPad properly because it keeps rejecting my Apple ID details ,even though they work fine on my computer itself. At first, I did the fingerprint login so I wouldn't have to go through Apple ID every time. I thought it was all settled when my finger-print was finally accepted. But now it's gone. I can only open the iPad starting screen but then the process of logging in to Apple ID starts and nothing I do is validated. I've been trying all day and have given up as I don't know what's wrong.A USB cable which came with the iPad doesn't fit into the ports on my iMac so I haven't plugged it in. However the iPad does turn on (for a short time) when I hold down the top button on the side of the iPad.
