Apple Mail Using Excessive Memory Recently, whenever I attempt to compose a message in Apple Mail, my entire system slows to a screeching halt and I have to shut mail down before I can have access to any other application. What's strange is that opening messages in my inbox and reading them has no effect on my computer's performance. I managed to boot up Activity Monitor during the most recent episode and it told me that Mail was using over 40 GB of memory. I'm no computer expert, but I'm fairly certain this is not supposed to happen. I've attached a screenshot for reference.



Has anyone encountered a similar problem and been able to find a solution? Or does anyone have an idea what might be going on and have a recommendation on how to remedy the situation? If not, no worries, I can take my machine to the Apple Store, but hoping to avoid that journey if at all possible. Thanks in advance for your time and assistance!
try to change the download attachment setting to recent or none.
Mail -> preference -> account -> download attachment -> 'none'/'recent'
