Yes, none of the Jetbrains IDE's seem to be usable on a 8GB Mac. It invariably starts throwing errors about running out of memory after a while and then everything starts to lag (including typing).

Also you can't really run any other process alongside as long as it uses above ~5000-1000mb (so no Node for instance). Having a browser with more than a few tabs open alongside is also an issue.

Maybe a ~5+ year old version might work better.
