Q: 20 desktops active and random glitches/freezes
As of recently I've noticed a few strange things happening on my macbook pro late 2014. These didn't start happening until a few months ago, leading me to believe some software update was responsible. Not sure if they're all related, but they are in order of ascending annoyance:
- 20+ desktops active at all times now. Used to be when I start up and go to mission control, I'd see one or two desktops depending on how many are in use at the top of the screen. Now I have 20+ without opening anything, and they're all blank. This is especially annoying when I actually try to use multiple desktops via mission control as since there's so many the window representing them is very small. If I swipe into expose that shows the correct apps open, so not sure why all the desktops are active.
- Sometimes if an app is full screen and the screen goes to sleep, upon wake the screen does not work correctly. This first started with one application and an external monitor, where upon wake instead of showing the app the screen would be completely black. By switching to other blank desktops (which show fine), I could eventually get it to show again, but would then have trouble bringing up the control bar on top to close/minimize it. Now recently, it's started to happen with all apps that are put in full screen. Temporarily when waking the screen, all full screen apps are totally black. After switching between desktops they eventually come back....for now.
- The most troubling are occasional seemingly random freezes due to CPU spiking. Can't see any reason for it, but somehow when watching the activity monitor I've watched a couple of apps manage to defy the laws of mathematics and leap to 102% of CPU usage, rendering the computer unresponsive. This usually only lasts under a minute, however I've had a few instances where it stayed like this until I finally just hard powered off the computer. The mouse was still responsive in these states, but clicking on anything or using gestures was impossible.
Anyway, not sure if anyone else has seen things of a similar nature or has any idea what all of this may mean. Thanks!
