Heads up. If you have a Mac and a second monitor using Intelli, hold off on upgrading to High Sierra

[Mark Spritzler]

Ever since i upgraded a couple weeks ago, my machine has gotten to a crawl. The solution to speed it back up is to disconnect my second monitor and then reconnect it. It isn't exactly IntelliJ's fault, but it is Java/IntelliJ that is causing the issue of IntelliJ taking up too much CPU % over 300% when there is a second monitor connected.

Some solutions says you just have to upgrade your Nvidia Graphics driver, but I have done that and it did not help me.

I am also on a 2013 15" MacBook Pro with 16GB ram and I heard 2016 and higher might not have this issue.

But be careful
