my macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty. I had to try myself as I'm overseas for two months and nowhere near any sort of help .

there was a recent software update that seemed to screw HDV up.  Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
Worst case scenario, do as Shane suggests.  But might I suggest you take a look at the user tips section of the forum.  there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.

  • The volume control on my MacBook Pro (running Lion) is not working

    All of a sudden I lost the ability to move the volume slider for my MacBook Pro internal speakers. It's permanently set to mute. I can't figure out! Every time I go into System Preferences and click "Sound" I get the spinning beach ball of death and crash out. Every time! Don't know where to go from here. Maybe my problem is bigger than the audio thing, but everything seems relatively ormal aside from this.
    If anyone has any insights, I'd really appreciate it!
    Thanks

    I sggest you reset the PRAM:

  • My Macbook Pro running Lion 10.7 will no longer connect to either my HP or Epson printers. Both printers report that they are connected to the correct wireless network and until 2 weeks ago work perfectly.

    My Macbook pro running Lion 10.7 will not connect via a wireless network to either of my printers, Epson and HP. Both printers report an excellent connection to the correct network. The Macbook reports "printer not found"
    Until 2 weeks ago all worked well. Both printers makes me think some setting in the computer must have changed.
    Any suggestions?

    System Preferences>Fax & Scan. Delete the printers and re-add them back in.

  • I have a new macbook pro running lion and want to update the software on my ipod touch. My old macbook ran 10.4.11 and won't update - but the new computer says I have to update on the computer I normally sync on or my music will be lost. Solution?

    I have a new macbook pro running lion and want to update to ios 5 on my ipod touch.  My old macbook only has 10.4.11 and can't be updated to lion - and won't update my ipod touch to ios 5.  But the message on my new macbook pro says I have to update on the computer I normally use for syncing or my music will be lost.  Is there any solution for this?

    try exporting your iTunes libary from the old computer to the new one
    take a look at this from apple

    I am not sure you have home shareing with 10.4.11 but if you do it works very nicely

  • I have a macbook pro running lion and it will not log on to a microsoft exchange server. any suggestions

    i have a macbook pro running lion and cannot log on to my microsoft exchange server.  Not a problem with my iphone and ipad are there any issues or fixes for this?

    I found the following suggested fix, posted by a user on Barnes & Noble's site:
    1. Create a folder in your Applications folder, call it: NOOKforMac
    Once you've done this, copy the Nook app to this folder. This should allow the app to run on the 1st or possibly second attempt to launch it.
    2. Once you're done using the app always quit it by clicking on the X (red in some cases) button of the application window (upper left hand corner)
    This seems to have resolved the issue and my guess is that somehow the .dmg volume path is somewhere hard coded in the app configuration.
    Elsewhere in that thread, the administrator advises calling Customer Service Team at 1-800-THE-BOOK (1-800-843-2665) and choose option 2 for Digital Support. 
    Good luck.

  • I have a MacBook Pro running Lion. I need to use Lion to run my Dragon. I would like to partition my drive to use Maverick for everything but the dictation software. I'm a new pie to apple

    I have a MacBook Pro running Lion. I need to use Lion to run my Dragon. I would like to partition my drive to use Mavericks for everything but the dictation software. I'm a newbie to apple

    To resize the drive do the following:
    1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

  • How can I move all my emails and mailboxes from my Powerbook 10.4 to a new MacBook Pro running Lion?

    I have an older PowerBook (OS X 10.4.x) and I need to move all my Mail (including mail I archived to folders) to a new Macbook Pro running Lion. 
    Can I just move the Mail directory (/Home/Library/Mail) and com.apple.mail.plist from the Powerbook to the MBP? 
    I noticed that the Mail directory structure on the MBP is different in Lion than the Mail directory structure on my PB OS X 10.4.
    I didn't want to overwrite the Mail directory on the MBP and find out I corrupted Mail on the new MBP.
    Any advise would be appreciated.
    Thanks.

    The safe "step 1," of course, is to keep an unaltered copy of the 10.4 Mail folder and plist so that if something bad happens on the new machine, you just throw out that folder and plist and try again.
    The safe "step 2" is that instead of dragging the folder into the same place on the new Mac, you can copy it to a separate location, like a temporary folder in Documents, then in Apple Mail in your new Lion MBP, use File/Import Mailboxes. It will ask you where the mailboxes are, and after you point it to that folder, I'm assuming it will import and convert them to the new format and place them in the correct sub-folders. If it goes well, you can then delete the temporary copy that you made for import purposes.
    The 10.4 plist might be too old since it's 3 major versions later; you can try putting it in the Preferences folder, but it seems safer to note all the settings in 10.4 and re-enter them from scratch.

  • Keep downloading Firefox 6.0.2 for Mac (as prompted) to my new Macbook Pro, running Lion (OS 10.7.1) and it won't open and install. WTF?

    I have Firefox version 3.6.22 (Mac) & keep downloading Firefox 6.0.2 for Mac (as prompted) to my new Macbook Pro, running Lion (OS 10.7.1) and it won't open and install. WTF?

    something similar has been happening to me for a a couple weeks (even before the most recent update, but now is definitely worse) on my 2010 MacBook Air. Firefox freezes upon startup, and then freezes maybe every twenty minutes or so when I'm actively using it, staying frozen for at least a minute or two. it drives me crazy.

  • Have a MacBook Pro running Lion and an IMac running Snow Leopard. Want to Back up both images and restore on opposite machine. Essentially swapping images between hard drives. Is this possible and any "gotcha's" to look for? Thanks

    Have a MacBook Pro running Lion (10.7.9) and an IMac running Snow Leopard (10.6.8). Want to Back up both images and restore on opposite machines. Essentially swapping images between hard drives. Is this possible and any "gotcha's" to look for? Thanks

    If the MBP came with Lion, it most likely won't boot with SL. Easiest thing to do is create a bootable backup/clone of each to an ext HD, partitioned to hold each on a separate volume, ensure that the original machines can boot with their respective clones, and finally, try booting the other machine with the other clone. Images are useless since you can't boot with them to test them out.

  • I am having trouble receiving email on Macbook Pro running lion.  No problem with cloud mail, but other accounts do not receive mail.

    Trying to set up email on MacBook Pro running Lion (10.7.4), I can send messages, but receive only messages sent to my cloud address.  Two other email accounts do not receive messages at all.  Passwords, etc are correct.  Anyone else have this problem?

    I am assuming you are using the mail app.  You may have turned off recieving mail function.  Open up mail.  HIt Command comma to open preferences.  Go into general and set it like this. 

  • How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver. I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. thanks

    How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver? I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. There are 4 HDMI-in ports on the receiver - BD, DVD, DVR/BDR and audio. In my system preferences for sound, the receiver doesn't show up as an output option. Can anyone please advise. (ps, this is my first time posting a question, so I hope I can find your answers!) thanks, JP downunder

    For sound, try the audio output port and connecting to the RCA  audio input ports on your Pioneer receiver.  Use something like this:

  • The iTune cannot detect my iPhone. I have already tried all methods suggested, including re-installling iTune, re-activating Apple Mobile Device, plugging in various USB ports, and etc. I use windows 7. How can I solve this?

    The iTune cannot detect my iPhone 4S. I have already tried all methods suggested, including re-installling iTune, re-activating Apple Mobile Device, plugging in various USB ports, and etc. I use windows 7. How can I solve this?

    The new cable is completely new, and my computer can detect the phone as a drive, and battery charging is ok. So I believe the USB cable works properly. It is so weird that just iTune itself cannot detect the phone, and it is of the most updated version. What else can I do? Thanks.

  • Can I run Windows XP on my 2010 Macbook Pro running Lion?

    Hi,
    I have a 2010 Macbook Pro running Lion. If I install BootCamp on it can I get Windows XP CD installed? I've heard compatibility issues so I'm asking here. Thanks.

    No. BootCamp in Lion only supports Windows 7.
