after updating my Imac to Monterey, my itunes library has gone. How can it be retrieved?
Firstly, a warm welcome to Mac-Forums. Thank you for your post
I'm afraid I have to ask you which Operating System (OS) did you have immediately before upgrading to Monterey?
This matters because if it was from Big Sur for example, there shouldn't be any change.
BUT, when you mention 'iTunes", I've got to assume that your last OS was several versions behind Big Sur/Monterey.
Until I know differently, I shall assume you had a much easier OS in which case iTunes has been replaced by "Music" (found in Finder > Applications > Music app).
Using Finder, locate the Music app and Click on it. Your Music should all be there.
Please reply and let us know if that solves your problem and, for reference, we'd like to know the previous version of OS before Monterey.
