I just got the new colored IMAC and tried to install my lightroom app and it couldn't download due to the software "needing to be updated and I need to contact the developer". Has anyone else come across this issue?
You should be able to run the latest Creative Cloud apps (2020 or 2021 versions). Apple have blocked old apps, so if you are using anything old, you need to get up to date. All part of the Joy Sof Mac.
