Mac Overheating Issue

Mac Technical Support
I will start off by saying my mac is old. I get this. My CPU temperature previously sat around 60 C when I raided or did anything intensive most of my graphics were on fair with a few sitting higher. After the patch, and I have everything on on low now, my mac runs at 80 C and will not drop.

Is there something I can do to change this? I don't want to over heat my mac and am unsure how even when I run the settings lower than previously my temperature will sit at 80.

I installed all updates and still have this issue. Thanks for any help or guidance.

I am seeing other users in the EU and PTR forums posting about this, and want to note that I have set my fps to cap at 40.
We're researching the overheating reports posted here.

One thing to note, for your iMac, you seem to have the ATI 2400 graphics chipset in it. This is unsupported for gameplay in 5.x, so this may be a factor in your case.
Joy. Guess I won't be buying the expac after all if I can't play :\ Wish Blizzard would understand the economy is tight and people can't buy a new computer on the fly anymore.
My MacBook Pro is running at 85 degrees C when I'm playing WoW, so I can't play until this is fixed. I've already bought the expansion so this is pretty disappointing. I'm also screwing over my guild who have lost me as a healer until this is fixed.

I have a different video card from Eadwig, too.

I also wanted to note that I know MBP's run hot but this is on an aluminum cooling stand next to an air conditioning unit...
My friend keeps trying to get me to come over to GW2 and and I refuse because I love this game. But it does suck knowing he's playing now and I can't because of the heat. I just wanted to make sure this is top priority? I see where there is a big hurry for a Darkmoon patch but no word on the many who can't even play!
I'm waiting on my MacBookAir. I hope this heating issue gets fixed before it arrives....this Tuesday. :)

If the MBAir doesn't do well, I'll get the MBPro.

Why didn't I get the Pro to begin with? Because it's toooooo heavy. I love the weight of MBAir and from what I've seen/read, it can play all Blizzard games.

Now, if only Blizzard's titles can be made to play on the iPad!!!! Oh, that would be sooo nice!
There's a temporary fix you can try. You need to do it every time you open WoW though. I do hope this problem gets fixed soon.

That is a very long fix just to be able to play without melting my computer.

My computer hasn't forced shut down from the heat but I am worried about such high temps for long periods.

Based on my experience with one Mac with an unsupported card and another Mac with a supported card, as well as the experiences of others on the forums, I don't think this is related.

Check out this fix (and the post below it as well) - it's been working great for me on both computers. http://us.battle.net/wow/en/forum/topic/6412493648?page=21#413
Guys! I think I found something to help!

You can toggle the 32-bit client from the launcher.

1. Open the World of Warcraft Launcher
2. On the system menu bar, click on Options and select Game Preferences
3. Check the option for Launch 32-bit client

This is something that is a known issue. For now, you will need to use the 32-bit client for movie recording.


My mac is old, but wow was trying to run it in 64 bit! So I did this and it dropped over 10 degrees while running wow. Still hot, but only a little hotter than what it was pre-patch. I hope this helps someone.

I didn't try that other work around as I am terrified of messing with command stuff xD
Anything about this issue yet?.. any info about when a fix patch will be released..
I've been completely unable to play for several days now because of this bug.

This didn't work for me.

The problem happens with both the 32-bit (~180% CPU) and 64-bit (~150% CPU) clients.

The "(Sticky) 5.0.4 Performance Issue (Similar to D3 Beta)" thread ( http://us.battle.net/wow/en/forum/topic/6412493648 ) shows this problem is happening to

NVIDIA GeForce GT 330M (a SUPPORTED graphics card) http://us.battle.net/wow/en/forum/topic/6412493648#8

ATI HD5770 (a SUPPORTED graphics card) http://us.battle.net/wow/en/forum/topic/6412493648#9

The problem is even occurring to WINDOWS machines with SUPPORTED graphic cards! -

I have an unsupported video card (ATI Radeon HD 2400 XT) as well and the trick at http://us.battle.net/wow/en/forum/topic/6412493648?page=21#413 drops the CPU usage from 103% to a much saner 8% at the log in screen

I used the where command and found this:

#0 0x00007fff8b6b704d in objc_msgSend_vtable1 ()
#1 0x00000001000247cd in GetBattlenetAllocator ()
#2 0x0000000100082e28 in GetBattlenetAllocator ()
#3 0x00007fff8e62872a in -[NSThread main] ()
#4 0x00007fff8e6286a2 in __NSThread__main__ ()
#5 0x00007fff922cc8bf in _pthread_start ()
#6 0x00007fff922cfb75 in thread_start ()

The few geeks who have researched this thing both here and in the EU (see http://eu.battle.net/wow/en/forum/topic/5208783244#1 ) have pointed to thread 7 and GetBattlenetAllocator () call in particular as the source of the issue (on the mac side).

It like everybody but Blizzard knows it is a coding-programing-compiling issue in the client and where it is.

So WHY in the name of sanity was the unsupported graphic card idea even suggested?
Because I'm sure that doesn't help. I am not getting crazy CPU or heat readings since I went to 32 bit. So for me, it was the fact a 7 year old graphics card and processor was trying to run 64 bit game.

Thanks for all the help and I hope a solution for others shows up soon!

As I pointed out I have a 5 year old graphics card and the kill the thread trick worked for me with the 64 bit client. Nevermind, that people with macs far younger (even ones made this year) are also reporting the same CPU overheating issues.

This issue is due to a programing bug and not the age of your machine.

Now why the GetBattlenetAllocator () call is running wild and cooking GPUs I have no idea (CPU makes sense but a GPU?!?).
I'm having this overheating issue too, on an early 2009 imac. It's kind of frustrating, considering Pandaria is about to launch. The fans on my computer start running, but i have the game set on low quality and low framerate. I was hoping Blizz would have fixed this by now.

If you have an issue regarding overheating, please start a new thread with the specifics, including your hardware and software information, as well as the exact problem you are seeing.

This thread is considered closed as it pertained to a CPU usage bug that has been fixed in the 5.0.5 client.

Machkhan, lock the door behind me please. :)
