My 2019 iMac is almost unusable as a result of it’s so sluggish. It isn’t a reminiscence difficulty as at the moment I’ve 30Gb unused of 64Gb. Simply typing on this window has lengthy lags. Simply typing “high -o cpu” in a terminal takes over ten seconds for a response. Extremely loading most net pages (e.g. WaPo) Safari freezes for as much as 10 minutes. System CPU use is at all times better than 65% typically within the 80% vary. WindowServer is at all times 25-65%, Safari, doing nothing can have CPU use > 30%, Mail typically peaks above 65%. Dropbox Seize makes use of 35% to 55% even when there hasn’t been exercise on Dropbox for days (and throughout a number of reboots).
Clearly there are main fails in Apple’s software program. On a newly rebooted machine, hardwired at 1Gb/s to web, a WaPo residence web page will take >5min to be scrollable or have any hyperlink clickable. My iPad Professional, over WiFi (300Mb/s) hundreds the identical web page immediately. Though most pages are painfully sluggish on the iMac (with some like WaPo being unusable) Amazon is at all times responsive. This is able to point out there’s some far past crappy programming by Apple for Safari on Intel iMacs.
Mainly I am getting at best possible on the order of 20% of CPU (doing something interactive with the iMac sends system CPU use to 80+%). Software program this crappy would get an F in a freshman programming class.
