[2021] EU4 not launching on macOS through the Epic Games Launcher.

Is your MacOS User Documents folder on your local disk, or has iCloud grabbed it? If the latter, that's a problem with the launcher at the moment - can you move it back?

If that's not the issue, then it's probably a file access/permissions issue in MacOS. Go to System Preferences > Security & Privacy. Then select the Privacy tab. Scroll down to files and folder in the left column. You’ll see a list of apps and the folders they need access to. Check the box to give access.

I doubt it, but I'm not sure what that has to do with the topic of this thread?  

Minke21 said: Having the same trouble here. Launcher is working now but it keeps crashing. I'm on sierra (10.12.6) which is, i'm guessing, the reason.
(DYLD, [0x4] Symbol missing)

bartosz.biel said: Put this command in terminal .. "chmod +x /Users/Shared/Epic\ Games/EuropaUniversalis4/launcher-installer-macos" Will fix issue

That command cannot possibly fix this DYLD issue, which will indeed be due to the launcher not working on that old MacOS version. Whether that's a limitation or unintended I don't know as yet.

@Minke21 @hyeou any chance you can update your Macs to something more recent, say 10.14 at least?  

Minke21 said: Well, as far as i know, no. Its an old laptop so it doesnt support the 10.13+ updates. Will wait if there is a solution in the future.
