Safari 14 extremely slow after download

Safari 14 installed automatically last night. Today, it is unusable as it takes several minutes to open a web page. My internet connection is fine since both my iPad and iPhone open pages quickly.


Sometimes I get the Safari Can’t Open the Page. The operation is not permitted (NSPOSIXErrorDomain1). This happened on Apple’s home page.

iMac 27″, macOS 10.15

My iMac has been restarting by itself overnight occasionally. The error report kept showing a symantec file in the report. I uninstalled Norton Safe (Xfinity/LifeLock free version). It appears that was causing the issues with Safari 14 after the auto download/install a few days ago. So far everything is back to normal
