Hi,
I have a 6 yr old i-mac running Catalina 10.15.7
It's been getting a bit slower recently but within the past few months mac mail has become almost unusable. Emails take an age to open - seems to be irrespective of size and in general mac mail just seems to run at 1/10 usual speed. I've tried rebuilding the mailboxes.
Any suggestions much appreciated.

Hello scott1129,
Welcome to Apple Support Communities. It sounds like you're having trouble with Mail on your Mac. We are happy to share information that may help.
First, try starting up in safe mode to see if that resolves the issue: How to use safe mode on your Mac.
You may also want to check for any available updates for your Mac: How to update the software on your Mac.
If those steps do not resolve the issue, please reply with whether or not you're experiencing slowness while using any other apps.
Take care.

Thank you Melissa,
So starting in safe mode cured the problem. But when restarting normally it returned. I noticed that Google Chrome is enabled to start at start up (even although it's unchecked in preferences). I deleted Google Chrome and the problem seems cured.
For now I'm going to simple do without Chrome.
Thanks so much, Scott
