How do I fix high CPU usage on Mac?

Jump to solution

For a while, ENS has been hogging my CPU. There are at all times anything between one and eight VShieldScanner processes, all reporting 100% CPU. This makes the computer more or less unresponsive.

I have not gotten much help from the logs in finding out what the problem is. Is ENS choking on some specific files? The log only tells me that the scan queue is too long, and sometimes that it doesn't like som file, more often than not it's a configuration .plist file or a file from the McAfee installation.

In my frustration I reimaged the whole computer, but when reinstalling ENS from our ePO the problem reappeared.

Any troubleshooting help would be appreciated.

When exactly you see this issue? during system startup or while running any specific applications?

Check if any scheduled scan configured to run at that time?

check for the recommended exclusions page number 40.

Thanks, the exclusions seem to really have helped, though not all exclusions seem to be accepted. The cpu issue is fixed, though I still see intermittent lag and freezes for a few seconds.
