    Last week I got Macs Fan Control to monitor the CPU temp. and I can confirm that 10.10.3 is causing my Mac to run too hot:

    I was playing Flash video today (Safari) and doing other things and my Mac shut itself off today. I started it back up and it got things going again and I watched the temp., it was hovering around 88ºC with the fan at max. speed, and I think it shuts down over 90º? So, 10.10.3 is doing something with graphics that is causing the processor to be getting too hot? (NOTE: this is also with the new Safari update.) Previously, I think the OS would do something to prevent overheating, but, ????? This has only been happening w/10.10.3, not any previous OS X, on this Mac, ever.

    (me: 2010 MBP 13") I've also has lockups w/10.10.3 (and not any previous OS X on this Mac).

    When a Mac shuts itself off, it's typically because the CPU is overheating, to prevent damage.

    So, it's not a hardware issue, nor is it specific to one Mac, I also see other posts w/similar issues on other Macs some say are related to graphics. (Crashes, kernel panics, lockups, warmer/hotter, shut itself off.). EDIT: I see these mostly posted in hardware forums.

    I hope apple addresses this w/10.10.4. I've seriously not had this Mac taken down like this.

    10.10.3 isn't one thing, you should be able to use Activity Monitor to find out which system component or App is contributing to the load - if you run in Safe mode with no logon items does the heating occur?

    Equally if you have installed any 3rd party fan control and get a heating issue, Apple may quite right;y ask you to demonstrate it still occurs with a standard config.

    That is actually good news :D

    Some OS X versions have been very conservative about GPU clocks — which limited graphics performance. I did some benchmarks in OS X vs Windows some time ago and I've seen that the GPU is running much hotter under Windows — which also was part of the reason why the Windows results were 15% better. If 10.10.3 allows higher temperatures, this means that GPU performance will be better.

    Of course, this should't happen with Flash, but thats Adobe's fault for awful programming... The task of the OS is to give you the resources, if you abuse them, its not really for the OS to blame.

    With all the variables possible, I don't really think you can draw any conclusions from that.

    I made a thread about this too.
    A user suggested a SMC reset which did work for me. Give it a try

    Flash heating up is not because of Adobe's awful programming. It's because Apple refuses to provide necessary graphical acceleration API to Adobe, hence Adobe can only push all the work to Mac's CPU. Doing graphical works on CPU is much less efficient than doing them on GPU.

    Haven't had any probs with my late 2011 MBP graphics card, and I have it set to run on AMD all the time. Never uses the Intel graphics. Doesn't run any hotter than normal.

    And which APIs would that be? QuickSync? Yeah, that's a bummer but in the meantime Adobe is welcome to using the accelerated video decode framework like everyone else.

    I doubt that is totally true, as, I decided to try Google Chrome again, and it actually uses a lot more CPU load than Safari, as Chrome emulates or uses flash offline.

    ----------

    There is no solution as of yet, we need to get apple's attention to fix whatever the issue is, as I think it's some kind of graphics bug in 10.10.3.

    • Please, anyone reading this, give apple feedback: http://www.apple.com/feedback/

    Select your type of Mac and be sure to select "Bug Report" from the dropdown.

    so we have to wait for 10.10.4 update?

    my CPU starts at 26c then shoots up to 35 to 40c within 10 mins
    same via bootcamp

    apple feedback is a lost cause they never get back to you:(:mad:

    Especially when the problem is a widely known 3rd party software issue?

    Its feedback, not support. If you want an interaction raise a support case.

    How is it a 3rd party software issue when just going from 10.10.2 to 10.10.3 causes the machine to run hotter or even crash? Sorry, no way.

    Of course anyone that has support available should use it! That would only be those that bought a mac in the last year or mac w/applecare within the last 3. Apple recommends everyone upgrade to yosemite, so, they should also hear from all of us that don't have support anymore, which is why I gave feedback link.

    Flash, and its optimisation, or not, isnt an Apple issue, its 3rd party.

    10.10.3 made my machine run cooler and consequently I get noticeably more battery life so your thread title is inaccurate in my experience.

    My point was that if you want an interactive discussion then support, not feedback channels are the ones to use, you were complaining that no-one from Apple responded to your feedback. In my experience you can call Apple support well outside the hardware warranty period if you are wanting support on a current product like Yosemite. You do of course have to be able to articulate a specific issue, vague complaints about the look of the UI cant be addressed by that route for instance.
