How come I can only turn on my Mac using Safe Mode?

When i turn on my MacBook Pro, the screen freezes on a white screen with a loading symbol and never completely turns on. I have to perform a Safe Boot by holding the shift key in order to turn the Mac on.

Apple has a good guide for 'gray screen' troubleshooting:

    How come I can't download anything from mac app store?
    I've tried everything it all started when my apple app store icon in the doc disappeared.
    It will not go to the Mac App Store
    I have a MacBook Pro 2010 intel
    os mac mountain lion 10.8.6 however I do not have the original copy that was downloaded from the app store when I bought it.
    I NEED TO DO A CLEAN INSTALL TO GET MY APP STORE ICON BACK
    Please if anyone can help apple doesn't seem to care?

    If you need to reinstall Mac OS X 10.8.x (there is no 10.8.6 yet, by the way), restart your Mac, hold down the Option key so you see all the bootable partitons, and boot to the Recovery Partition. From there you can reinstall Mountain Lion. You will need a good Internet connection.

  • How come I can only get 200 of my 700  songs to show on my display in my new truck?

    My operating system has nothing to do with my question but I was asked to enter the info. I have a 4th Gen iPod & do not know why I can only get 200 of my 700+ songs to show on the display in my new truck. All my songs are from purchased CD's or iTunes. The dealer of course has no idea why this is happening. Please help.
    Thank you,

    This needs to be done manually, either by transferring them from the first computer, or using the Transfer Purchases function if applicable, or by clicking here and following the instructions.

  • How come I can only paste 1 email at a time into ipad mail?

    I am trying to paste a comma delimited list of emails ([email protected], [email protected]) into the "to" field on the native mail app on my iPad 2.
    Is there anyway to keep it from combining the pasted email addresses as one contact?
    Can only copy/paste 1 email address at a time into those fields (to, cc, bcc)?

    I am also trying to paste multiple emails into either field and it isn't working; what the ****? If this is the case I will return this junk. No wise *** comments saying 'iPad isn't a emailing device' please.

  • After downloading the new update for Firefox I can no longer get Firefox to respond. I can only get it to respond in safe mode. Why?

    After downloading the new update to Firefox I cannot get Firefox to respond. The only way I can use Firefox is in Safe Mode.
    == This happened ==
    Every time Firefox opened
    == I updated to new version of Firefox

    Cannot believe NO ONE from Firefox is responding to this issue; particularly since I don't seem to be the only one with the problem!!!!

  • How come I can't print a full page using the fire fox "print" mode /

    When printing, even in the print preview mode it only shows the middle of the page and I cannot print the entire width of the page ??

    You probably have messed up left and right margin settings.
    Try the '''''reset''''' described here: <br />

  • How come you can't stream photos from a primary library that is "paired"?

    I think someone else commented about this as well but I never really saw an answer as to why Apple doesn't allow this. How come you can only stream from a shared or secondary library but for a primary or "paired" libray you have to sync photos. If you can stream from a primary it is not working for me.
    Thanks again ATV community!

    It's behaving correctly for you, you cannot stream photos from a primary library. Why I don't know, the software has gone through several stages and various options have been offered, so I can only assume it's not an oversight but a deliberate restriction for the better.

  • How can I use Safe Mode to troubleshoot in Windows 8 or Windows 7?

    QuestionHow can I use Safe Mode to troubleshoot in Windows 8 or Windows 7?
    AnswerWindows has a special mode known as Safe Mode. It is not fully functional, but it allows you to make changes to the laptop to hopefully fix normal mode. We're going to attempt to boot into Safe Mode to use it fix the laptop.
    For more information on how to boot into Safe Mode please see the following articles:
    How To: Safe Mode and other Advanced Startup Options in Windows 8
    Creating a System Repair Disc for Windows 8 (useful for entering Safe Mode)
    How To: Start your Windows 7 computer in Safe Mode
    Use Safe Mode to undo recent changes
    When a computer won't start Windows, it's usually due to a recent change. If you installed a new piece of software before your laptop began to have trouble booting, you may want to uninstall it. Similarly, if you recently made a change to any system settings, you may want to change it back. If you have antivirus software, you may want to perform a scan. If you're not sure what to do here, feel free to skip to the next step!
    Use Safe Mode to perform a system restore
    Windows includes a utility called System Restore that can help with many problems. While this won't alter or remove any of your personal files, it will roll back your system settings and files to an earlier date. We'll use this to attempt to fix Windows.
    To learn how to use System Restore, please check the following articles:
    How To: Understanding System Restore, Refresh, Reset, and, Recovery options in Windows 8 + Video
    How To: Perform a system restore in Windows 7
    Use Safe Mode to initiate a clean boot
    As Windows loads, it loads many additional components such as services and startup items. Some of these are not vital. For example, some tools start immediately with Windows, such as antivirus software. From Safe Mode, we can instruct Windows not to load many of these. This will help you determine if one is causing Windows not to load properly. Note that this step is more advanced than the previous steps. If it seems difficult for you, you may consider asking for help from someone who is more comfortable with computers.
    Please view the following article for more information:
    How can I perform a clean startup without my startup items to troubleshoot a problem?
    If Windows loads normally, you'll know one of those startup items or services was causing the problem. If this is the case, you may want to return to the System Configuration Utility and re-enable some items and services to determine which specific one caused the problem.
    Backing up your data
    If you're able to enter Safe Mode, backing up your data should be easy. Connect a USB flash drive or external drive to your computer while in Safe Mode and then copy your important  files to the flash drive or external drive.
    You may also want to consider taking your computer to a professional.

    Would love to know if this is possible. Found forums dating back years asking exactly the same thing, no solutions. And I do not want to change my headset (Sennheiser MM-50), or use the onboard mic (which sounds like you are using your Mac in a wind tunnel once the fans kick in).

  • HT1614 How come I can't see "Nike+" option in itunes when I plug in my iphone? I have it turned on in my iphone and have work out data in it.

    How come I can't see "Nike+" option in itunes when I plug in my iphone? I have it turned on in my iphone5 and have work out data in it.

    Hello Kanji0513,
    Thank you for using Apple Support Communities
    I found this bit of info about the way Nike+ works on the iPhone and iPod Touches versus the way it works with other model iPods.
    Your iPod touch or iPhone 3GS or later wirelessly sends workout data to nikeplus.com from wherever you are on the road. So right after your run, you can track your progress and analyze your performance. If you walk or run with iPod nano, workout data is sent to nikeplus.com when you connect it to your Mac or PC.
    From: http://www.apple.com/ipod/nike/sync.html
    The option in iTunes only appears if you are not using an iPod Touch or iPhone.
    All the best,
    Sterling

  • How come I can't add a song to my playlists in itunes match? Is it me or itunes match? It keeps on coming up with a message " iCloud playlists can only contain songs from your iCloud music library. If you continue, the playlist will be removed from iCloud

    How come I can't add a song to my playlists in itunes match? Is it me or itunes match? It keeps on coming up with a message " iCloud playlists can only contain songs from your iCloud music library. If you continue, the playlist will be removed from iCloud and will only be available on this computer"?
    You must surely be able to add and subtract songs on specific playlist?

    I fixed this issue (with help from tech support) and it involved several things.
    After adding a song to iTunes, right-click on the song in iTunes and select "Update iTunes Match."
    OR go to the iTunes menu-->Store-->Update iTunes Match.
    Maybe that's the reason, it just hadn't updated to the cloud.
    OR maybe it's not a high-enough bitrate file.   This happens to me because most of my tunes are home-recorded.
    Sometimes converting to .mp3 or Create AAC version might work. (You do this with a right-click in iTunes, and then you will want to remove the original file from iTunes.)
    There is an iTunes Preferences setting, under General Preferences called Import Settings.  Try setting it to AAC Encoder and iTunes Plus.   That (I think) causes imports to be slightly better quality.
    Good luck!  The tech support person at Apple is requesting that a knowlege-base article be written about this.

  • How come I can't put music on my ipod? I already have a fair amount of music on my ipod but I have enough space for more. I am using a new computer with itunes and it is telling me if I wasnt to put the new music on my ipd i need to erase my ipod HELP!

    Because you can only synce with one iTunes library and you are switching libries by using the new computer. To nake this yyour syncing computer:
    - Move all the media(apps, music, synced video and photos etc) to the new computer.
    - Connect the iPofd yo the computer and bake a backup fo the iPod by right clicking on the iPod under Devices in iTunes and select Back Up
    - Restore the iPod from that backup.
    Note that the backup that iTunes makes doe not include media.
    To move mdia to the new computer see:
    iTunes: How to move your music to a new computer
    iTunes Store: Transferring purchases from your iOS device or iPod to a computer

  • HT2404 I just clicked on Software Updates; BUT nothing shows what's happening? How come I can't see the updates & time it will take?

    Help!  I just got this Lion, and SO many changes & not necessarily for the better !
    I went to the Apple icon, but  "Software Updates" did not show ... though I had deferred installing some updates ...
    Finally it showed up, I clicked on it, saw the updates to do - BUT when I clicked on install - the "box" that usually shows the updates & how long to install - just disappeared! I can't get to it to see what's next. (I have to leave soon & will turn off the mac)
    What's happening? How come I can't see the updates as they are installed, & how much time it will take?
    How do I know IF they have been installed?  Is this the "new Normal" for Lion? Or is there a glitch in my mac somewhere?
    How about updates you download from Apple (not bought) - they go to Downloads on the Sideboard, but are they installed automatically, & put where they belong too? Is there no more restart, etc.?
    - I just went to Systems Preference, to see the "Installed Software" - shows they were ... but don't I have to restart anymore? Are all updates now automatically placed where they belong?
    Thanks to any who can help
    PS One other question - just checked my "profile" & it has my email addy that's 4 years old... how do I change That?
