Activity Monitor cannot display complete info

Hello BenhoN,

Welcome to the Apple Support Communities. I understand some columns are missing in Activity Monitor. I'll do what I can to help get them to return.

The columns to view will be in the 'View' menu in Activity Monitor up top. After clicking View, then go to 'Columns' and selected the columns you want visible. You can also control- or right-click where the column are supposed to be and check the ones you want visible.

Cheers.

Delete this file…

~/Library/Preferences/com.apple.ActivityMonitor.plist

While in the Finder, press "command shift G". Copy and paste the line I posted and hit enter.

You're welcome.
