But I don't want to spend all the time to do that unless I have to. No syncing apps, no Dropbox, Google stuff or anything like that.Īnyone have any ideas as to what else it could be, or what else I could try to narrow down the issue? The only thing I can think of is reinstalling macOS, and if that doesn't solve it downgrade to Mojave.
This is basically a fresh install of macOS, all I've installed is the Brave web browser, Spotify & Pixelmator. *Closed down all applications, issue still happens *Created a new user account, had the same issue there *Checked keychain and cannot find any red/corrupted keys Suspicious 0 OS and Allwinner H313 64-bit Quad-Core ARM Cortex-A53 CPU. These are the things I've checked so far: Download VLC Media Player and install it on your Windows PC or Mac A copy is. When I restart the Mac the CPU usage goes back to normal for a while, then starts having the same issue again. The processes are: nsurlsessiond, trustd & syslogd When checking the Activity Monitor it shows there are 3x processes (they look to be related to macOS) hogging CPU usage, making it constantly sit around 25-30% system usage. Immediately after upgrading I noticed the battery was running down fast and the Mac was running hot. It was a fresh install, and after using it with no problems for a few hours I upgraded to Catalina so I could install some newer apps. Click the CPU menu header to change the order.
The app or process listed at the top is currently using the most CPU. You will be presented with a large window showing CPU usage with a scrolling display of the apps using percentages of CPU clock time in descending order. So I purchased a 2015 rMBP with an older version of macOS on it (Yosemite I think). To launch Activity Monitor, select Applications, Utilities and Activity Monitor.
