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

Firstly, don't keep read mail in your system if you can avoid it. I would also ask: are those Microsoft apps really necessary? They alone add up to 469.4 Mb, just 80.2Mb less than your email usage. What is it about Microsoft apps that Apple apps can't do? Or are they part of your work ethic that you just can't afford to get rid of? That's perhaps understandable given that a large proportion of the business universe seems to be tied to nowadays.

Hello


Thank you for your reply. I am running my own business and need to keep all e-mails on my Mac for various reasons.


I move emails from my inbox into folders setup in Mac Mail on my machine which generally removes them from online.


Not sure if this helps, welcome any suggestions,


Thank you

I could suggest moving them to iCloud, or perhaps an external hard drive e.g. WD My Passport with a capacity of 1 Tb which should accommodate all of your business emails for the forseeable future.

You showed 549.6 Mb of email usage, but your business emails, even if they are off line, means that you are still using that amount of email space. If there are any that you can delete without it affecting your business, then I would suggest offloading as many as you can afford to lose.

In your initial message, your ma had used up nearly 6 days of CPU time, but in your second message, 'accountsd' was using just over 6 days of cpu time even though they are off line.

Here's a short video that could show you what is actually taking up CPU time: https://youtu.be/4Vct4WMIb4Q

Here's another that could explain what constitutes 'Other' (fast forward to 3 minutes 27 seconds): https://youtu.be/hp3SlXohKq0

Hope it helps.
