Unlock the Vault, use the Mac OS Preview to open a pictures, then try to lock Cryptomator. The app freezes and prevent the mac to restart.

Welcome to the Cryptomator Community ,

we are already aware of such a bug if one uses WebDAV as the virtual drive provider (shown in the general preferences), see

github.com/cryptomator/cryptomator

### Please agree to the following - [X] I have searched [existing issues](https…://github.com/cryptomator/cryptomator/issues?q=) for duplicates - [X] I agree to follow this project's [Code of Conduct](https://github.com/cryptomator/cryptomator/blob/develop/.github/CODE_OF_CONDUCT.md) ### Summary When trying to quit Cryptomator while there are open files on the volume, Cryptomator will hang i. e. become unresponsive. ### What software is involved? - Operating System: macOS Big Sur 11.6 - Cryptomator: 1.5.19 (dmg-2838.133) - Mount method: WebDAV ### Volume Type WebDAV ### Steps to Reproduce 1. Mount a volume via WebDAV. 2. Open a file in the volume, e. g. a PDF document in Preview. I have found that just an open Finder window also triggers the problem. 3. Quit Cryptomator. 4. Cryptomator asks whether it should unmount and lock the volume. ### Expected Behavior Cryptomator returns an error message that unmounting and locking has failed because of open files. Ideally Cryptomator would also list the relevant files and / or apps. In any case the user can close open files and then try again. ### Actual Behavior Cryptomator hangs, i. e. becomes unresponsive. No error message. No quitting. No retry possible. In fact it can mess up the WebDAV side so badly, that the machine in total misbehaves, gets sluggish. In this state a restart of the OS is not possible without force quitting apps / processes or force restarting. ### Reproducibility Always ### Relevant Log Output _No response_ ### Anything else? Diligently make sure, that there are no open files on the volume and no Finder windows / tabs before quitting Cryptomator and / or unmounting the volume, locking the vault.

The WebDAV implementation on M1 Macs is buggy, hence, we recommend to use macFUSE instead.

Hi @DavidL, I think it’s worth trying to change the webdav port. For me it looks like a good workaround but I have only been testing for one day.
