Acrobat Reader and RdrCEF each consumes over 50% CPU on Mac when I just only one pdf file. Could anyone help? Thanks!

Hi there

 

Hope you are doing well and sorry for the trouble. As described, Acrobat Reader and RdrCEF each consumes over 50% CPU on Mac

 

Would you mind sharing the version of the Mac OS and the Adobe Acrobat Reader DC you are using? To check the version go to Help menu > About Acrobat and make sure you have the latest version 21.07.20091 installed. Go to Help > Check for updates and reboot the computer once.

 

Also go to Adobe Acrobat (Mac) > Preferences > Page Display > Under Rendering, uncheck 'Use page cache' > Click OK and reboot the computer once and see if that works.

 

Regards

Amal
