Mac Mail Excessive CPU usage
Hello,
I am having major issues with Mac Mail on my 2014 MBP over the past few months.
Having Mac Mail open significantly slows down my laptop, runs the fan's hot and the Mail application itself is slow. I have checked the activity monitor and frequently it uses more than 300% CPU, recently I am also seeing messages of low memory.
The Mail was slow before the latest Mac OS, but it seems to be much worse now. At times, I have to force quit and restart for the Mac to respond. I have also tried disabling the gmail and hotmail email addresses, leaving just Office365 and my mac mail account, in addition to disabling the option to 'automatically manage connection settings', not to no avail.
Can anyone offer any advice please?
Please find screenshots attached.
Thank you, Liam
