I am unable to open my CR3 files taken with my new R5 body in the RT macOS dev build I use as suggested in the RT macOS Catalina FAQ, which I took from @HIRAM’s key base at kd6kxr/ – Keybase.pub. I use the RawTherapee_OSX_10.9_64_5.8-397-g276ae214f. Do I need a higher dev version if I want to open my R5 raw files? I am unable to compile my own RT or ART on macOS as I posted in two previous posts here and here. Would it be possible to make new macOS version available that supports the R5 raw format on your keybase, @HIRAM?
