High CPU usage for Mail.google.com in Safari

Have anyone noticed 50% CPU utilization when you open gmail (mail.google.com) ?


This seems to be a repeated behavior. Not sure whether it is just me or anyone else have noticed it.. I switched from Chrome to safari due to heating issues in MBP.


MacBook Pro 13″, macOS 10.15

Hey bharatcrs,


You are very welcome! We appreciate you for completing those steps.


You may want to consider using the Mail app on your Mac and signing in with your Gmail account there.


Let's try setting your Gmail account in Mail using this resource: Add an email account to Mail on your Mac


Accessing your mail this way may cut down on the higher percentage of CPU utilization on the Mac.


Hope this helps!

Hey bharatcrs,


We see that you are having some concerns with the Gmail webpage consuming a large amount of your Mac's energy in Activity Monitor. You have come to the right place for guidance.


Here is a resource that provides some tips and troubleshooting in regards to the Activity Monitor settings: See how apps affect Mac performance, battery runtime, temperature, and fan activity


In regards to your MacBook Pro having some heating issues, we suggest reviewing this resource: Keep your Mac notebook within acceptable operating temperatures


Kind regards.

Hey bharatcrs,


We totally understand if you would not like to add the mail account directly to your Mac for concerns of storage limitations.


We recommend clearing out your browsing history as well as your caches and cookies in both browsers as this will reset the amount of activity that was previously stored.


To clear out the browsing history for the Mac, check out this resource: Clear your browsing history in Safari on Mac


To clear out the cache as well in your Safari browser, follow these steps: Open Safari > Choose Develop in Safari menu > Empty Caches


If you still have Chrome downloaded on your Mac and would like to complete this troubleshooting there as well, check out these resources:


Clear browsing history in Chrome: Clear browsing data


Clearing out cookies and caches in Chrome: Clear, enable, and manage cookies in Chrome


Once you have cleared out this information, you should hopefully see a difference in the CPU percentage in Activity Monitor on your Mac.


Best wishes.
