My mac heats up on normal apps

My mac heats up on normal apps like watching youtube videos on chrome. If this was to happen, this did not happen until now. Also, while playing light 1-10 megabytes games my mac heats up to 80 degrees celsius (176f). This did not happen until today.

supersaiyanidiot,
you can try resetting your MacBook Pro’s System Management Controller to see if that affects the temperature.

  • How much real world difference would there be between the 1600MHz memory of a 4,1 Mac Pro and the 800MHz memory of a 3,1 Mac Pro? My main app is multitrack audio with Pro Tools. Thanks so much.

    How much real world performance difference would there be between the 1600MHz memory of a 4,1 Mac Pro and the 800MHz memory of a 3,1 Mac Pro? My main app is multitrack audio with Pro Tools. Thanks so much. The CPU speed of either one would be between 2.8GHz and 3.0GHz.

    What are the differences.... firmware and build, there were tweaks to the PCIe bus itself. As a result 3rd party cards and booting is better.
    Support in 5,1 firmware for more 56xx and W35/36xx processors. Also memory timing.
    The 4,1 was "64-bit boot mode optional" and 5,1 was default. I don't know if there are changes but I assume so, even if it is not reflected elsewhere or in version number.
    I don't know what the prices are but 2009, to buy one today, when the 2010 is $1800.
    The 2008 of course was test bed for 64-bit UEFI and it sure seems even Lion and then ML are not as well engineered - outside of Linc who would be the least likely to have a problem.
    I would assume 2010 has better support for 8GB and even 16GB DIMMs as well as for 1333MHz.
    Nehalem family had only come out in fall 2008 and a lot of work went into making improvements well past 2009.
    If you remember, there were serious heat problems with those and 10.5.7+ up thru 10.6.2 even with iTunes, audio, and hyperthreading and cores hitting and staying in 80*C range. That I assume was both poor code (sleep does not mean poke and ask constantly) as well as changes in SMC and kernel improvements, to work around. Microcode can be patched in firmware, kernel, by drivers and by code, but it is best when the chips and core elements don't need to be.
    If someone is stretched, and can get 2009 for $1200 it might be a fine fit. That year offered the OEM GT120 which isn't really as nice and matched for today both OS and apps that rely on a GPU. And for odd reasons two such 120's don't work well in Lion+ but that is probably minor. Having the 5770 is just "nicer" though.
    There are some articles about trouble booting with PCIe SATA/SAS/SSD and less trouble with 2010. Also support for graphic card and audio I think was one of those "minor" 5770 related support issues. But shows some small changes were made there too.
    I wish someone would come out and pre-announce DDR4 + SATA3 along with PCIe 3.x (for bandwidth and more power per rail) along with say Ivy Bridge-E socket processors was going to be this summer's 3 yr anniversary and to replace the 2010 designed motherboard. But that is what is on Intel's and others drawing boards simmeringn in the pot.

  • Can you download normal apps such as clash of clans on iMacs

    can you download normal apps such as clash of clans on imacs

    Is your question really about downloading apps from other sources than the Mac App Store? Yes you can, but you will likely need to change the default setting in System Preferences/Security & Privacy/General/Allow apps download from:

  • Two libraries on one mac (mini) visible using remote app, how?

    Hi all,
    I would like to have multiple libraries on one mac so i can access them via my remote app on my ipad
    Reason;
    I have 700+ albums in different musical areas. I can only see the album art when i am in the library of the remote app. The different playlists dont show artwork but just the songs.
    If i can make different libraries i have a better overview of all the art work
    Does anyone know how to make both libraries on the same mac, visible on my remote app?
    thanks in advance
    Frits

    I don't think the issue is one of Apache (not even sure it's one of named virtual hosts since you want both sites to serve the same content). The issue is one of having multiple .local names point to the same machine.
    I don't know this can be done without your own DNS server running in the network.

  • TS1702 We use one ID for  the Apps store for 2 iPhones. In the second profile on the Macit is impossible to update apps there is a mistake. What is the decision?

    We use one ID for  the Apps store for 2 iPhones. In the second profile on the Macit is impossible to update apps there is a mistake. What is the decision?

    This happens when you both use the same Apple ID for iMessage.  To fix this you have two choices:
    On one of the phones go to Settings>Messages>Send & Receive, tap the ID, sign out, then sign back in with a different ID.  Note: you can still share the same ID for purchasing in Settings>iTunes & App Stores; or
    On both phones go to Settings>Messages>Send & Receive and uncheck the email address(es) shown under "You can be reached by iMessage at".  Also uncheck the other phone's phone number, if present.

    I have an Apple iphone 4s and for the last 4 weeks I cannot download or update any apps. I have an iPad and a Mac book pro and the apps download on these devices fine. My phone tells me that I have 12 updates but when I press update all or update any individually nothing happens at all. It also does not ask me for my password any more but my iPad and mac book do.
    I have signed in and out of the app store and the password is correct. I have tried both kinds of reboot but that did nothing. I have tried to update the apps by connecting phone to Mac book pro...it shows the apps being download on the Mac book and says it will sync them to my phone but it does not. Everything else on my phone works fine.
    Any ideas ...Please!

    Thank you, this has resolved both the iphone and ipad problem immediately.  I am concerned that I may have a problem with apps that I bought under my old  AppleID as they will not be recognised.  Any suggestions for this please?

  • HT4007 Already have Aperture 3 license, how do I install it on another Mac without rebuying it from App store?

    Already have Aperture 3 license, how do I install it on another Mac without rebuying it from App store?

    As you can see from all the replies to your question if you are not clear in describing the situation it is very difficult to try and help you.
    So first how did you originally purchase Aperture? App Store, DVD or Unlocked Trial version.
    If you purchased it from the App store if you log into the App Store with the same Apple ID you used to purchase Aperture then you will be able to install it on other systems besides the one you originally installed it on. Even though the button says Purchase you will not be charged again as lolongnd as this is the same Apple ID you used the first time.
    If you installed from DVD or Trail unlock post back.

  • I updated Adobe Flash on my Mac and now my solitaire app won't open.  No error message, just -600.

    I updated Adobe Flash on my Mac and now my solitaire app won't open.  Message just says 'unable to open' -600.  I tried to reinstall Full Deck Solitaire, but the app store says it is already installed, so I can't do it that way.  What should I do?  There's nothing in Help that helps.

    Please restart the computer and try again. If it won't restart in the usual way, force a shutdown by pressing and holding the power button for a few seconds. Then press it again briefly to restart.

  • Macbook pro md313 over heat, is it normal ?

    Macbook pro md313 over heat, is it normal ?
    i bought macbook pro md313 2 days ago, its really really over heat it burns my legs and very loud fan, is it normal ? and if its not how to fix this problem ?

    Without any real data we cannot give you any advice.  Install from the Internet iStat pro and then you will be able to see the actual internal temperature and fan speeds for your MBP.
    In the mean time be advised that there are temperature sensors that will shut down your MBP before it commits Hari Kari, so do not be unduly alarmed.
    Ciao.

  • I accidentally deleted the Reminders only on mac section in the reminders.app on mountain lion. How do I get it back?

    I accidentally deleted the Reminders only on mac section in the reminders.app on mountain lion. How do I get it back?
    I checked @ http://www.apple.com/osx/whats-new/features.html#reminders and it says under Multi Accounts: "Reminders works with CalDAV services like Google Calendar and Yahoo! Calendar. You can also create reminders that appear only on your Mac."

    Quit Safai (double tap the home button, hold the app icon until it wiggles, tap , double tap the home button gain)

  • I purchased the 30 day subscription of Adobe Pro for my Mac Air and downloaded the app and opened it as instructed. Nothing appears to happen after that and I have been unable to use Adobe Pro thus far.

    I purchased the 30 day subscription of Adobe Pro for my Mac Air and downloaded the app and opened it as instructed. Nothing appears to happen after that and I have been unable to use Adobe Pro thus far.

    I previously downloaded a trial version of Adobe Pro and had used it the last 30 days. Today I just clicked on the link from my purchase confirmation and downloaded some type of installer. Once I clicked on the installer and gave it permission to do whatever it needed to do, it just sort of stalled. I am running Mac OS Yosemite. I thought Yosemitie might be part of the problem because it has given me occasional problems with Word and some other programs.
