Mattermost 5.2.2 no window opening on MacOS when starting

[agriesser (Alexander Griesser)]

Hi Thomas and welcome to the Mattermost forums!

Although this issue should have been fixed with 5.4.0, it seems that it isn’t
Please watch this thread, I’ve asked one of the developers for help there:

Mattermost on Mac - Window not showing

Thanks, so this is an updated installation. It seems as if there’s again a problem with the download location picker which cannot be opened and maybe is related to what you’re seeing. @devinbinnie any idea how to force the app to store the downloads location again (if this is the issue)?
