222 Processes Running
There are currently 222 running processes gobbling up memory and CPUs on my Macbook pro, causing it to heat up and turn its fan on. That seems too much. I am running iMovie, Firefox (just one tab), Dictionary, and Activity Monitor
I noticed this problem worsen after:
1) El Capitan install (at behest of Apple support)
2) Turning on iCloud.
I have Airplay and a bunch of other crap that I neither want nor need.
In addition to being slow and running a bunch of unknown **** that I don't want and most likely don't need, my Mac's 500 GB internal hard drive is mostly full of "other". I couldn't figure out what "other" was after searching. What is it and how can I free up memory (I already turned on iCloud and deleted a bunch of stuff)? Why is my mac so busy? How do I identify other undesirable processes like AirPlay, et al and then uninstall them?
Thank you.
