Client starts twice on Macos

On MacOS the client starts twice after a reboot. One of them crashes, the other is unresponsive until the crashed version is killed in Activity manager.

We have two MacBooks that connect to Nextcloud AIO, both have this behaviour. On is on Macos Tahoe, the other on Sequoia.

It looks rather similar to this issue described in German (my German is meh, though).

How can this be solved?

I found a report on github with an old launchAgent that launches the app a second time. It seems that you can disable this:

And it seems that they fixed the bug for the next release 33.0.5 (not sure if there is a release every 4-6 weeks or so).

Yes this Grisey commment explained the solution for me Multiple App Instances · Issue #9929 · nextcloud/desktop · GitHub
