Hey, I was also having this issue on iMac (Sonoma 14.3.1 (23D60)). I had to uninstall GOG multiple times, toggle the login settings, and also move the installed GOG folder from shared into my user's folder.. I hoped this helps some of you. I really wanted to play the new Stardew update and I would have rioted if I couldn't. Shame on GOG for not addressing this directly in forums tho

I have the same issue. To be fair, there have been messages similar to this one filling the logs since the release of MacOS 14 last autumn - with the app being unable to close.

So this looks like a bad bug that GOG just haven't fixed in more than half a year - they're really, really bad at maintaining their client.

2.0.73 Beta (2023/11)

Issue still remains when connected via RDP. Connected via Parsec instead, GOG launches flawlessly.

I have the same issue. Was unable to solve it.

M1 mac on Sonoma 14.4.1

I had the same problem, multiple reinstall, and deletion of some or all files manually was not wark.

I find out that after installation only Galaxy component was mark as enable to run in background in my settings, but gog sp. z o.o. was not - after I click on that switch my client start to work normally :)

Hopę this help some of you I louse few days to figure that out because after installation I always get info new items was added to background setting (or something like that) so I do not even think to check it.
