i was planning to try out Nix on MacOS, because i always wanted to try out Nix and i use MacOS, but then Catalina happened,a and suddenly there were problems with Nix on Catalina.

last time i checked the install-instructions on Catalina, you had to create an unencrypted volume to store the nix-things, which i'd prefer not to do (i understand those files are probably non-personal, so no need to encrypt them, but i don't want to have to remember that half of my hard-drive is unencrypted)

is that still required or is there a simpler approach now?
