Since updating MacBook Air to Sonoma I had multiple processes called 'CGPDFService'

Since updating to Sonoma I have had 2 periods of up to 10 instances of a process called 'CGPDFService' running causing all 4 efficiency cores to run at 100% for extended periods -- hours, they never seem to stop themselves. Once they started in the middle of the night and ran a few hours when the Mac was asleep. It ran the battery down more than usual.

A restart seems to fix it for a while but I wonder if anyone else has any insight into this. I can't find any info on what this process does. I am hoping that it will be fixed with the next update.

I have a MacBook Air m2 running Sonoma 14.0.

Thanks Luis Sequeira1. Before you replied the first time I ran Etrecheck and found launch daemons and plists for Adobe acrobat which I had uninstalled some time ago. I removed everything from Adobe [in safe mode] and now everything looks ok on Etrecheck. If the problem recurs I'll open another question and include an Etrecheck report.

I have the same problem.

I had disabled spotlight PDF indexing in System Settings, and reboot my Mac.

But huge CGPDFService still appears.

14.4.1? I thought the last version of Sonoma was 14.2.1? Or maybe I'm I wrong? :-)
