Mac book pro running hot

My mac book pro is running very hot. My fans are going like crazy but it doesnt seem to be doing the job. Should i try to clean my fans or something?

yeah, same here, my fans seems to be running above 6000rpm ALL THE TIME, even when i'm on preview and itunes, and when safari isn't open.  i keep mail and calendar open all the time, but other than that, i understood that word, excel, preview, and the like weren't supposed to tax the system much, but my CPU temp is at about 90 degrees.

  • Whenever Retina Mac Book Pro runs HOT - FCPx runs NOT - And it does so A LOT

    These past weeks I have been doing more and more work on the Retina Mac Book Pro. Only thing that has been bugging me is that I cannot seem to rely on its performance. At times FCPx is blazing fast and others so slow that one could think I was running it on an iMac from 1998.
    Once it gets slow... It will take about 5 seconds for a clip that I select in the event browser to appear in the viewer. And i.e clicking the inspector will take about 4-8 seconds for it to open...
    So I decided to troubleshoot.
    Basically it is VERY simple.. Whenever the fans start churning on the Retina Mac Book Pro, the whole app simply quits performing. Shutting down the computer for about 10 minutes will alleviate the problem. Other strange thing is that no other app seems to be affected by this issue. PPRO, AE, Photoshop, Aperture, Safari etc etc etc... Only FPCx and Motion. I have not experienced this problem on any of my Mac Pros.
    Problem is that the fans start spinning like crazy only after 10 min. of working in FCPx. And that with Proxy Media.
    I have been noticing that people on newer (Thinner) iMacs are complaining over performance issue and wonder whether those might be heat related as well.
    If anyone else are experience such issues, I sure would like to hear about it. And if anyone has suggestions to a possible workaround I too would love to hear about it as this is killing my workflow !
    Thanks

    me no engineer ... ahh, you did know that!
    but …
    Aren't FCPX + M5 the apps in your list which rely most on the graphic card? I'm not familiar with Grand Central and other OS-designs, nor can i confirm a built-in heat-sensor for that part of the Mac, there are sensors erverywhere - why not?  …
    But if I had designed the graphic-card as co-processor, this would be essentiell.
    And your observation and conclusions make a lot of sense!

  • Using multiple desktops with a 4 finger swipe on a Mac Book Pro running Lion- is there a way that I can allow Safari open on several but not all??  Looks like I can set it for one but not others.  All, one, or nothing

    Using multiple desktops with a 4 finger swipe on a Mac Book Pro running Lion- is there a way that I can allow Safari open on several but not all??  Looks like I can set it for one but not others.  All, one, or nothing

    Hey Eric,
    Thanks for taking the time. Unfortunately no that does not solve it. Same as swipe it will get me there and it will show separate programs spaced out. The issue I am having is that all my open word files are bunched up in a pile on top of each other. I can see the edges of each one but I want them to be separated from each other enough that I can visually identify what file is what.
    Again, thanks for trying, it is appreciated.

    You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

    The 2009's didn't support sound on HDMI. That came in 2010. Are you sure it ever worked?

  • Is it possible to install Lightroom 2.0 onto a Mac Book Pro running 10.8.5?

    I have a disc for LR 2.0 and I am trying to install it onto my Mac Book Pro running 10.8.5.   I have tried three times and the installation has failed with a message saying contact the manufacturer.
    I have managed to install Lightroom 1.0 from disc and it opens but will not allow me to create a new catalogue.
    Is this just a compatibility fail?

    Try installing 2.7 from here: Adobe - Lightroom : For Macintosh   Historically, installing a download has often worked better than installing from CD.

  • How do i download 10.9 or 10.8 if i have a 2008 mac book pro running os x 10.5.8

    how do i download 10.9 or 10.8 if i have a 2008 mac book pro running 10.5.8

    I might also add your signature is not in congruence with your post.  Do you have 10.8.5, or 10.5.8.  10.8.5 is a free update to 10.9.   10.5.8, you must buy 10.6, download the free 10.6.8 combo to get to 10.8 or 10.9 via the App Store.
    The sequence of the numbers matters greatly.
    Per my prior post
    10.5.8 < 10.6< 10.6.8 < 10.7 < 10.8 < 10.8.5 < 10.9
    People just wanting 10.7 from 10.5.8 can purchase either 10.6 on CD, download 10.6.6 combo, and use the App Store to upgrade to 10.7.   They can also purchase the 10.7 USB Flash drive if it can be found, and install it on an external drive, and import the data over once they are ready to run 10.7.
    The key is knowing your software and driver compatibility.

    Hi, I have a mac book pro running mavericks and recently tried to connect to a 3rd gen apple tv but the airplay icon is not showing up in the top bar. I then tried my girlfriends laptop running mountain lion and it showed up straight away. Any suggestions?

    How old is the MacBook Pro?  AirPlay is only supported on 2011 and newer models, due to the requirements it has in hardware for graphics acceleration.

  • Hello. My safari (and i keep it updated) cannot open PDF files. Should i install Adobe Reader and which version????? I have Mac Book Pro running OS 10.9

    My safari (and i keep it updated) cannot open PDF files.Should i install Adobe Reader and which version????/ I have Mac Book Pro running OS 10.9
    Please help me!!!!

    Back up all data.
    If Adobe Reader or Acrobat is installed, there should be a setting in its preferences such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected. Otherwise do as follows.
    Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
    /Library/Internet Plug-ins
    In the Finder, select
    Go ▹ Go to Folder
    from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
    From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
    The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list.
    If you still have the issue, repeat with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

  • I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this?

    I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this? It bugs me when I'm looking at real estate.

    I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
    When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

  • One of the users on my Mac book pro, running Mountain lion finds that no changes made in last session are there next time they log on

    One of the users on my Mac book pro running mountain lion finds that no changes made in last session are there next time they log on.
    For instance, the Macintosh HD icon, is always moved so that it is almost off the screen to top left hand side of the desktop.
    None of my changes to the sidebar in the finder are there.
    My changes to the dock have reverted.
    Despite unticking the box when logging out, even though i have quit all applications, iphoto and safari are always re-opened.
    iphoto always says the library needs to be upgraded... even though i did that the last time.
    I have tried deleting ALL the files in the "Saved application state" folder in the library folder, but that doesn't seem to make any difference.
    This is on a second admin user account.
    The main user account seems to be fine.
    This account used to be in the filevault on Lion, but is not now in Mountain Lion.
    Can anyone help?
    Thanks

    The same tragic thing happened to me, not even a full two days after I bought it. I immediately powered it off, wiped it as best I could, and put it in front of a fan. I tried valiantly to get the back off, but couldn't remove all the screws. I was basically inconsolable until I realized that no matter what, my credit card insurance would cover it, since it had been less than 90 days. Fast forward 48 hours, and it seemed to run just fine. Some of the keys and the track pad were sticky, and I figured since it was covered, I might as well get it fixed. My only concern at this point was had I voided the Apple Care. I brought it in, told them what happened, said what I needed to satisfy the credit card, and they said, "We'll just swap it out for you, no problem." I was thrilled, and the Genius said they appreciated my honesty, and it was easier for all parties to just do it this way. And my Apple Care was transferred to the new machine. This was my first Mac and, needless to say, I am now an Apple devotee.
