From https://cryptomator.org/downloads/ I can read that minimum requirement, for macOS, is 10.11.
From https://docs.cryptomator.org/en/1.4/desktop/setup/ I can read that maximum requirement is 10.15 (Catalina).
So the question is: is Big Sur officially supported? The question is related in some ways even with FUSE: last FUSE release for Mac, 3.11.2, I don’t know if it’s compatibile with Big Sur seen that FUSE community gives a generic macOS 10.5 minimum requirement.
It’s a very critical thing as all my data are encrypted with Cryptomator.
