Photos stuck on "Updating Library" after upgrading to Monterey.
After migrating my data from my old iMac running El Capitan, most of my photos did not make it (probably around 60K+ of them). I have since upgraded to Monterey, and my Photos app is stuck on "Updating Library". The most I can get is 10% completed, and nothing I can do will stop the process. Since all of my photos are on the old iMac that still runs, I don't really need them on the new computer. How can I stop the updating process? I must say I much prefer iPhoto because of the additional photo editing it allowed. I just can't seem to get used to Photos!
