Mac FS-UAE Launcher Network Connectivity Issue
 

I installed the latest ARM versions of FS-UAE for Mac and couldn't get Launcher to connect to the OpenRetro repository or to the fs-uae.net to download settings for WHDLOAD images.

I run Little Snitch and thought that was it – but disabling it (or setting up rules) didn't work.

It turns out that it was Adguard that was blocking the connections. If this happens to you, go to the Network tab of Adguard's prefs and add exclusions for the two domains in the Filter HTTPS Protocol section.

Thanks to Frode to responding to my Discord message and pointing me in the right direction.

Good idea to post about, I think three people have independently reported the same issue by now (and it looks to be caused by the same software) :)
