My Apple Mail has all of a sudden become incredibly useless. The trouble started back on Monday and I thought the issue would resolve itself. It hasn't, even after multiple restarts. In fact, the issue is plaguing both of my iMacs, very strangely at the same time and in the same way. I don't know what's happening. All I know is that if Apple Mail is closed and I open it, I have about 5 minutes to do e-mail before it starts going VERY slow and then a minute or two later stops responding all together and I have to force quit and do the process all over again. I finally took a look at the Activity Monitor and why it's freezing is obvious. I have 3GB of RAM (maxed out) in my 24" iMac and Apple Mail is taking nearly 2.5GB of real memory at the time of it crashing, and almost 4GB of virtual memory. What is causing this? In the meantime, I virtually cannot send e-mails and this is very hampering to me. Is this an IMAP problem with GMail? I imagine that's the only thing that would explain this given that's the only thing linking the e-mail on both of my iMacs. But if so, what's going on?!? Any help is appreciated.
