My macbook air (early 2015) is running slow!
Hello! Just recently my MacBook air started running very slow. I have run EtreCheck and found there is a runaway app which was using a very large amount of CPU (262% when I first ran). Also approx 170 gigs of hd space is going to "system".This Etrecheck report I am pasting below was done while in safe mode. Any assistance would be very much appreciated!!
MacBook Air 13″, macOS 10.14
