I have been working with Cryptomator and Dropbox on my MacBook M1 using WebDAV with few issues other than slowness working with larger files (>1GB).
Since upgrading to MacOS Sequoia 15.2 late last year, Cryptomator is unworkable. When I try open or even right-click a file, Finder crashes and I must force restart the computer.
I have tried using MacFuse and FUSE-T, both are even worse than WebDAV. They struggle to even mount a Volume, let alone allow for file access.
The only WARN in the debug log is:
11:17:27.528 [App Background Thread 006] WARN org.cryptomator.common.vaults.Vault - Unable to add Vault to quick access area: Desired implementation not available.
I am running version 1.14.2. I fear the issue is related to the MacOS update, but unfortunately it is non-trivial to reinstall an earlier OS on Mac.
