What does operating temperature mean?

http://support.apple.com/kb/SP5
Apple states that the maximum operating temperature is 35 degrees Celcius. Does that mean that my Macbook can be, at max, 35 degrees Celcius, or that the temperature around me, while using my device, can be, at max, 35 degrees?
Thanks, so much.

Also pay attention to "storage temperature".
Car trunks in deep summer can easily exceed both humidity and temperature limits.
And car tunks in deep winter can easily lower the temperature of all components even deep in the Macbook.  You may want to allow your Macbook some time to slowly re-warm from deep freeze.
If your Macbook will be in storage for a length of time (2+ weeks) you may want to leave it with a friend who has controlled-environment if your only other option is a storage unitsthat has no controls.

  • What does memory low mean and what can I do?

    what does memory low mean and what can I do?

    The iPad is low on RAM which is the memory that the operating system and apps need to run smoothly and efficiently. You can close apps and that might help. Restarting or rebooting the iPad might help as well.
    To close you apps, tap the home button. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button twice.
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

    What does this message mean Charging is not supported with this device?

    You've gotten 2 good answers already, but there's a key assumption in both that you got the message when connecting the iPhone to some other device. If this is the case you can get an adapter in the Apple online store that will allow charging from older devices.
    If, however, this message appears when you are not connected to anything the problem is dirt or moisture in the dock connector at the bottom of the phone. Clean it with a dry toothbrush or air blast.

  • What does this message mean? : "The file name "DSC_0088.jpg" is offline or missing." ?

    What does this message mean? : "The file name "DSC_0088.jpg" is offline or missing."   I am in the process of importing photos from iPhoto (don't really know what I'm doing....) and when I look at one of the imported photos that message pops up.  I know what "DSC_0088.jpg" is.  I don't know what it means that the file is "missing".

    CASpyr,
    Thank you so much for your reply.  I have a couple of bigger issues that I am dealing with: too many photos on my laptop: 40,000! (Of course I have to throw away many of them, but that is time consuming). I have a MacBook Pro and have primarily used IPhoto. I have recently purchased 2 external drives and have transferred my photos to those, but I need a basic education about how photos are stored, copied, etc.  I have recently been told that iPhoto only shows and deals with jpegs, not RAW.  About 1/3 of my photos are RAW, so I purchased Lightroom, so I could do more with those RAW photos.  I have been told by my local Mac store that I need to delete most of my photos from iPhoto, because it's causing problems.  I am reluctant to do so until I am sure that all of the keywords, descriptions and editing I have done to these photos is not lost when deleted from iPhoto. I just watched a tutorial about importing to Lightroom and got out of it that I needed to copy photos from iPhoto to a file on my desktop and then copy to Lightroom.  I did that, it seemed to work.  Then (because of my storage/memory issues) I deleted the photos (just a few as an experiment) from that desktop file.  I'm guessing that is why Lightroom doesn't recognize the the photos.  It seems that (learned from another tutorial) that one uses "Add" , Lightroom is only connecting to the source of the photo, not  actually copying it to the program.  Sounds like I need to use the "Move" feature instead.  My ultimate goal is to store the photos on the 2 external drives and eliminate most of them from my lapop.  So my basic questions have to do with what data (metadata??) is copied from iPhoto to an external drive (RAW???) and what isn't copied. Basic understanding issues,obviously….  I hope this isn't too much to ask.  If you can recommend a book or resource that can explain those basic issues to me I'd appreciate it.  I just got back from a trip and I can't download my new photos until I manage the rest!
    Thanks,
    Nancy

  • What does this message mean? "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired"

    What does this message mean? "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired"  I get this when I try to repair permissions in disk utility.

    It's an innocuous error you can ignore. It was introduced with previous updates for ARD and/or Java before Lion. These are messages, not errors. They will cause no harm, and they will be repeated each time you repair permissions.

  • What does this message mean: "power pc applications are no longer supported"?

    What does this message mean: you can not start because power pc applications are no longer supported?

    Here is a post that I assembled for another who needed to continue to run his PowerPC applications in Lion/Mt. Lion:
    Unfortunately you got caught up in the minor miracle of Rosetta.  Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
    However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion).  While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
    Workarounds:
    1. If your Mac will support it, restore OS X Snow Leopard;
    2.  If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between your PowerPC software or Lion/Mt. Lion;
    3.  Upgrade your software to Intel compatible versions, or find alternative software that will open your data files;
    3.  Install Snow Leopard (with Rosetta) into Parallels:
                                  [click on image to enlarge]
    Full Snow Leopard installation instructions here:
    http://forums.macrumors.com/showthread.php?t=1365439
    NOTE: STEP ONE of the instructions must currently be completed on a Snow Leopard or Lion Mac and the resulting modified Snow Leopard.cdr install file can then be moved over to your Mountain Lion Mac for completion of the remaining steps.
    NOTE 2:  Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization.

  • ITunes.  After installing new software, what does "restore iPod" mean?  Does it mean to restore all games and data to the new software or does it mean to "undo" the software update?

    iTunes.  After backing iPod to computer and installing new software, what does "restore iPod" mean?  Does it mean to restore all games and data to the new software or does it mean to "undo" the software update?

    You can restore your iPod to "New" which will erase every thing and install fresh iOS software or you can restore to a particular backup that you have previously created. In this case, your iPod Apps & data will appear as per the backup. Note that some content is not in a backup and will need to be synced back to the iPad from the iTunes music library or from, for example, the iPhoto photo library.
