My 2015 Macbook Air is running REALLY slow...like you drag a window and it pauses to think about it. I've uninstalled everything looking for a culprit. I found an article that led me into the console logs. I see the item on the log below ALL day long, making md think its the problem: GmailNotifrHelper. Problem is, I uninstalled this. How do I really get rid of it???
