SLOWDOWN after Big Sur installation Macbook Air 2014
Hey Everyone,
I have a Macbook Air 11" 128GB currently with 45GB free space, and 15GB space taken by "system" category.
Since updating to Big Sur, I've experienced reduced performance out of the Mac. I used to have El Capitan or Yosemite (have not completed OS update for awhile, or ever since unboxing)
Prior to update it used to be able to handle having x2 chrome windows open, one running up to 5+ youtube tabs (not all playing simeltaneously) with another window with 10-15+ tabs for general browsing, while playing music or potentially with photoshop / quickmovie etc in the background. It slowed at times, but always managed great.
Now, I don't even try having x2 chrome windows opened simultaneously, and if i go past 2-3 youtube tabs, or have multiple open, I get significant lag when trying to do things such as open a new page, open a new tab, minimising the window even the 'right click' option menu lags or freezes sometimes. Just overall general slowdown. I can't see how this update would cause such a drastic difference. I read the warnings to have free space when updating, and think 45GB is more than adequate for the OS to not be at the end of its tether.
I've downloaded / paid for CleanMyMacX and utilitsed essentially all of its tools to free up as much as possible but no luck.
Anyway, any advice / guidance on this much appreciated.
I'm thinking of moving back to previous OS, but as it hadn't been updated since unboxing I dont think this is possible? I'd actually have to do essentially a factory reset and start from Yosemite?
thank you.
