Yosemite OS 10.10 Mail Memory Leak

Y'll should count yourself lucky that you found this easy and simple fix in time. I, however, was not so lucky!! Hauled my computer to the "Genius" bar and after the tech guy practically laughed in my face at the notion that my Mac mail would eat up 65GB+ of RAM when I only had 8GB worth I insisted there was something really wrong with it. So they took it in (ended up keeping it for 6 days) installed brand new RAM and when my computer still failed their stress tests and continued to freak out over the application memory they determined my ONLY option was a complete hard drive wipe. Yep, you heard me right. Everything was backed up so no biggie there, but here I am now having to re-install EVERY.SINGLE.APPLICATION I had on my hard drive and then having to now order my online backup and reinstall ALL my files. This is the epitome of PITA!!! All over a silly little check box that I need to uncheck in my Mac Mail. Ugh, go figure!! Ok, rant over...or is it... ;-)

Wauw well that proves it than this is a bug big time ! I sent report to Apple but no followup, went to an Apple store, they do not have a clue, chat neither no clue.

Installed it on one iMac only fortunately, typing away on a Maverick Macbook Pro Retina now. I quote another poster: " These issues are reminiscent of Microsoft. Apple's big benefit was stability, well made hardware, and well made software that "just works." This is just not the case right now. Not trying to be a negative here, just stating things as objectively as possible." And this is now the 4th time I experience this ***** in 2 years, this runaway memory is by far the biggest. Spotlight not working and ending up in an runaway reindexing loop upon Maverick upgrade was the second one.

Bluetooth connection since Yosemite is very buggy and slow no comparison to Yosemite.

Apple Shame on you, this pathetic not wanting to respond when there are major problems, even if it is only 10000 users or so you should act. I have been using Apple computers since 1986 and you are becoming complacent about your QC procedures, upgrades like these that are on the outside pretty minor should work period !!

These last few threads dashed all hopes for me to upgrade to Yosemite. Thank God I followed my rule that of not upgrading to the latest OS immediately but leave a few months. Decided: NO TO YOSEMITE. I STAY WITH MOUNTAIN LION.

Check this out 😉

I have tried "garanda" post, and it did not work. I mentioned this in my original post. I wish this worked. I tired it.

Exactly. The garanda post suggestion & link does not fix this issue. I also stated in my original post that I had already tried those things. It does not fix this Mail issue. Please read the complete thread prior to posting and test things yourself & post your results instead of redirecting people to a solution that does not work for our situation. I appreciate the enthusiaism but it's misdirected. Thank you.

I wish I had 😟

I may have misspoken in my response above...I did the unchecking/checking of certain boxes within my IMAP godaddy email account and while I have not had any application memory errors for my mail, I am actively watching my Activity Monitor and Mac mail is again running around the 50GB mark and the memory pressure gauge is all red. Anyone else having similar issues who have done the mail "fixes" noted in previous posts??

The "Drafts" temp fix I suggested was the only box I needed to uncheck to stop my memory leak issue. I have not experienced any other memory issues since doing that. I'm sorry to hear that you're having issues still or anyone else for that matter. I know how badly that s_cks.

For me, the combination of unchecking both the save drafts box in mail prefs AND removing everything from my startup items folder in library seemed to stop the leak. Here's what I deleted (below). It's been almost a week since I've had the 'you have run out of system memory' issue. Make sure to check both the System and HD libraries.

I don't even remember owning some of this stuff (compacpcpcpestart from 2005 - what's that? I've never even owned a compac computer. All Mac since 1986.) - which is the problem with migration assistant. Super convenient - but we carry over crap to our new machines that should have been left behind.

So even though I just had my hard drive wiped clean and its basically a brand new machine (I have not imported files from backup yet) and I'm still having a memory leak you think this will help??

Just a thought - is it a refurbished machine? Are you a GoDaddy user?

I have been having the same issue with my iMac since I upgraded (more thinking it's a downgrade) to Yosemite and I have 16Gb of Memory. This looks like an issue Apple needs to resolve! 😠

Nope, not a refurbished machine...it's only about 18mos old. And yep, I am a Godaddy IMAP mail user. Does anyone think switching to POP account would solve that? Godaddy gives you options for using either IMAP and POP.

Dear all, Thank you for this thread.

Obviously I have this problem too and been suffering from it greatly in my daily work. It got so bad I started using Postbox in the meantime (which is actually a very nice Mac Email program, I particularly enjoy the possibility for labels).

So, on my computer it became soon clear that the memory drain is worst when I was writing an Email, even worse, when there was an attachment attached!

I did like most, monitored with activity monitor and restarted when the RAM was too low.

I am using two iCloud Mail accounts, one POP and one IMAP GoDaddy.

And YES, unchecking "Store draft message on server" for the IMAP GoDaddy account DID remove the problem.

The second Mac in our house did have NO problem ever (it runs an iCloud Mail account and an Exchange one, NO Go Daddy account.)

I hope this adds to the data collection. Many thanks!
