System is running our of application memory after yosemite install

I've started getting the same issue. Never happened under Mavericks...

My MacBook Pro:

• MacBook Pro (Retina, 15-inch, Early 2013)
• Processor: 2.7 GHz Intel Core i7
• Memory: 16 GB 1600 MHz DDR3.
• OS X Yosemite

Me too.

Only running mail and safari, and it also never ever happened under Mavericks.

On thing I've noted is that Mail is now always in the "Apps using significant energy", never did before hand.

The is the first time I've regretted upgrading.

• Macbook Pro Retina late 2013.
• 2.3Ghz i7
• 16GB ram
• Os X Yosemite

Try and reset the PRAM

Restart your computer and hold down

CMD + OPTION + P + R

Thanks - An Apple Technician

That seemed to work. Mail not reporting using significant energy anymore.

Bit of dumb question (but it's always good to learn), why would resetting the PRAM solve the problem?

I'll keep an eye on it and see if the problem returns.

Thanks

Getting the same issue today. I've been running Mail and all of my normal apps (Calendar, Messages, Safari, Reminders, Pages) since I updated to Yosemite on launch day without a problem. All of a sudden today I've gotten two "application memory" warnings and have had to quit all programs, restart, etc. without any luck.

Tried the PRAM reset as mentioned above so we'll see how that helps. Not sure how doing that keeps the Mail app from draining application memory, though.

Thank you for the suggestion. I did a reset of the PRAM but still get this issue... 😟

It seems Mail has a memory leak as it is the only app I have to force quit. Also, it seems quite intermittent as I had to force quit Mail twice in quick succession while I was typing an email but I haven't need to force quit Mail for the past 40 minutes...

matthew,

Have you checked Activity Monitor (Applications>Utilities folder) to see what may be eating up your RAM? I, too, have 16GB of RAM and can keep multiple Adobe CC applications open along with Parallels and at least a dozen applications. I've never had an out of memory warning.

Check out your RAM usage in Activity Monitor and see if you've a runaway process running.

Good luck,

Like everyone else (it seems), my issue is with the Mail application.

I did do a PRAM reset and haven't had the issue since. We'll see...

Spent the day working with multiple apps open, including Final Cut Pro X, so here's to hoping it's been cleared up.

Thank you, Joe and @clintonfrombirmingham for the info.

My Activity Monitor did show a massive surge in memory usage for Mail. It is quite shocking to see Mail's memory usage go from 103MB to trying to go over 12GB in less than a minute!

Oh well, time to wait for a patch...

Since the problem seems to be fairly widespread, I'm sure that it's near the top of Apple's bug-et list.

Having same problem but on:

iMac 27" Mid 2011 2.7 Ghz Intel Core15 32GB 1333 Mhz DDR3 Memory Yosemite 10.10

AND not on my MBA:

MBA 13" 13" mid 2012 2 Ghz Intel core i7 8GB 1600 Mhz DDR3 Yosemite 10.10 memory from activity monitor 141.5mb and rather steady

Is anyone else having this separation problem? Is it the architecture or Yosemite? Mail accounts are identical. The Mail app on the iMac is constantly growing but it remains stable on the MBA. Whassup with that?

The iMac can grow to 70GB with little effort just using the Mac. That does not happen with the MBA.

HMMMMMMM thought maybe time machine but thats off. Running Sophos on both machines. Never had problem in Mavericks and now see that it seems to be only on the iMac but see others with MBP having same same problems. Anyone else with MBA?

Thanks. This is quite problematic. Maybe sell the iMac and just get big monitor LOL

Also did PRAM did Disk Repair and permissions repair. Seems to be holding steady Cap'n must be the old dilithium crystals....

I tried this after "Memory Clean App" said I only had 1 gig left of the 8 and now I have 4 of 8 available. Thanks for this suggestion.

dang it. It went well yesterday and then today in the middle of an important email reply I once again received the dreaded "out of memory" window. The activity Monitor showed that once again Mail had climbed to over 70GB. Now I compose in a text editor then cut and paste. This needs to be fixed but how? Its bringing back memories of the old "Conflict Catcher " days.

I eliminated all but the essential start up items reset PRAM and now will empty mail trash to see what the heck is happening.

Is anyone finding any joy out there on this? Still only seems to be happening on my iMac not my MBA.
