Photos is at Version 7.0; appears there are later versions, but will not update
How do I update a 2021 iMac running Monterey 12.0.1 from Photos Version 7.0 to whatever the latest version is? I try doing System Updates, but Photos doesn't go to a newer version. I think the Photos version that was on the previous very old iMac ported over and I can't get it to update. Please help. Thanks.
iMac 21.5″, macOS 10.13
