CGPDFService problem, sky high memory pressure and usage

Again, today they started to run after I was done using Preview. I was simply surfacing the web on safari with activity monitor open. I did run the etrecheck and it found no major problems. I guess I will use my old Mac; this is a nuisance.

Could you post that EtreCheck report? You can always access your previous reports under File > Previous reports while running EtreCheck itself.

EtreCheck can't uncover the cause of complex problems like this just by running it. What it does is reports on lots of other data points. By combining 3 or 4 of those various data points together, we might be able to take an educated guess about what is causing this.

Also, in Activity Monitor, try running it in Hierarchical mode. All of those CGPDFService processes are started at the same time. Hierarchical mode might show what process started them. Also, you can use the "info" ⓘ button to find out more about a process, such as who started it, what it's doing, etc. You can post that information here in a reply too.

Information in this thread: Since updating MacBook Air to Sonoma I had multiple processes called 'CGPDFService'

suggests the problem is related to Spotlight.

Go to System Settings > Spotlight and uncheck "PDF Documents".

And please follow-up if that fixes the problem.

Do you have any PDFs open in individual browser tabs concurrent with observing these CoreGraphics PDF services running?

Worked for me, thanks. But this is a joke. We don't need this when we're happily working with no PDFs or anything opened and all 4 efficiency cores maxed out. Still had the 8 performance cores mostly unused, thank God. But it is annoying.

Again, mate, thank you so much for fixing it for me.

I've tried everything, and NOTHING has worked. I knocked the PDF off of Spotlight and all the other suggestions. Still, I'm using a huge amount of memory for this.
