which is the best photo editing application for Mac
How do I extract my photos from old Appeture library to "Photos" or recommended app?
Question marked as
What is the best will depend on the person asking - what do they need, what is their budget etc etc.
Many people swear by lightroom (monthly subscription) which I think can import from apertuere.
Others:
OnOne
Luminar
Affinity
Capture One
Mylio
Etc. You are going to have to evaluate and decide which meets your needs most.
