I thought it might be good to have a central location to look for software and hardware that have some issues with Big Sur.
Bartender 3 is not compatible
Bartender 4 is in beta now, and is compatible with Big Sur. It is a paid upgrade (US$7.50), which I’m happy to pay. It’s free while in beta, and for four weeks after.
FYI: Rogue Amoeba has a status page where you can monitor the compatibility of their products. Hopefully, they’ll all be compatible when (or soon after) Big Sur launches.
Don’t forget RoaringApps. They’ve been at it for years. Sometimes a bit hit and miss, but useful nonetheless. I see they also have a category for Apple Silicon.
