I recently upgraded my 2018 Mac mini from Ventura to Sequoia. My Mac is well-equipped with a 6-core CPU, 32 GB of RAM, and a 1 TB SSD. However, since the update, I’ve experienced significant issues with two processes: `SystemUIServer` and `configd`.
Initially, the issues are subtle after a fresh boot, but over a day or two, the situation worsens. After a few more days, I am plagued with the infamous beachball and a constantly revving fan. The CPU usage of these two processes adds up to 100%, which is a curious “Apple math,” as this represents 100% out of a total of 600%.
What’s perplexing is that they don’t independently reach 100% each; they always seem to be tied together in their misbehavior. My system is relatively clean, with software that I actively use, and there are no signs of malware. I’ve already gone through my LaunchAgents and LaunchDaemons to remove any outdated entries, but this had no effect.
I sought help on the Apple forum, but their only suggestion was to wipe my system and start over, which seems unreasonable. The first two diagnostic steps would be to A) perform a clean install of Sequoia on a USB SSD to see if the problem persists, and B) create a new user profile and check if the same issue occurs. However, as it takes a day or two to manifest, these steps would be highly inconvenient for me.
I also have three monitors connected and utilize seven different virtual desktops, resulting in a total of 21 virtual displays. I wonder if there might be a bug relating to multiple displays that affects performance, which many users wouldn’t encounter. Since this is my primary device, it would be challenging to limit its functionality for several days to troubleshoot effectively.
I welcome any suggestions or insights on this issue.
