Uh-oh. Apple Photos started saying my full-resolution photos will no longer fit on my Mac. I have 80 GB free on a 500 GB SSD, but Photos is still complaining. I’m debating what to do about it. A huge part of my backup strategy is using Arq backup to back up my full-resolution photos (the entire library, really) to Backblaze B2. Maybe I will export all my photos (the originals) and copy them to B2, then turn on “Optimize Storage”, and then stop trying to back up my originals on my Mac. I’m not getting a new Mac with a 1 TB SSD in it anytime soon, unfortunately. What a pain.
