I’m stuck using Facebook Messenger, and they love trashing system performance in the browser, so I tried the “native” macOS app recently.
I’m not sure what I did, but after posting a sick medieval meme, it started reloading itself over and over. Kill, open, repeat - it just hung. Stuck cache? This is starting to turn into a theme…
I figured deleting cache things worked last time, let’s try it again…
rm -rf "./Containers/com.facebook.archon/Data/Library/Application Support/Messenger/Partitions/*"
Opened, and it was OK again. Sigh.
