In order to uninstall Lion and "downgrade" your OS, you have to erase your drive. There is no other way. If you have a bootable clone or a Time Machine backup, it is easy - just boot with it, erase the drive, and clone back. Or, do you have your install disks? Boot from that disk, erase the drive and reinstall.
Make sure you back up your important files first since they will be gone.

  • I have just bought a new mac book, and I want to start from scratch by syncing the content of my iPhone, but each time I try it wants to delete everything on the iPhone and replace by what on the new iTunes library, i.e. nothing! can I do the reverse?

    I have just bought a new mac book, and I want to start from scratch by syncing the content of my iPhone, but each time I try it wants to delete everything on the iPhone and replace by what's on the new iTunes library, i.e. nothing! can I do the reverse, i.e. importing all my iphone's stuff on the new computer?

    You need to copy some files and your iTunes folder to the new computer. Do you have a backup of your old computer (or still have the old computer?) Was the old computer a Mac or PC?

    Hi,
    We changed the iCloud account on the Mac Book and now we can not use some part of iCloud like Documents, etc on the Mac book to sync to iPad.
    It says it is not the principal account.
    Regards,

    The iPad and the Mac need to be signed into the same account, 2 different accounts won't work

    Welcome to the Apple Community.
    Unfortunately, if Apple simply allowed people to log into different accounts and download content, everyone would be using everyone could share everyone else's content and bypass the need to purchase anything. To protect against this, they limit you to logging into a new account to once every 90 days.
    If two or more of you, have different accounts and use only one computer, you should each have your own user account on the computer, to avoid the need to log in and out of iTunes.

  • After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

    The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
    PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

    Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.<br />
    You can use "Firefox > History > Restore Previous Session" to get the previous session at any time.<br />
    There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.<br />
    Another possibility is to use:

  • I have an older Power Mac G5 Quad, and my video card just went out. I am trying to find a video card that will work for my Power Mac. I have duel screens but I can't seem to find the appropriate video card

    I have an older Power Mac G5 Quad, and my video card just went out. I am trying to find a video card that will work for my Power Mac. I have duel screens but I can't seem to find the appropriate video card. The serial number on my computer is: RM620603R6W. Apple won't help me because the computer is older than suggested. Please give me the exact video card that will work best for my computer.

    Hi Mike, make sure the card has Mac ROM, or is a PC card with Mac ROMs flashed to it...
    G5 PCIe options are listed here:

  • I've bought books and now want to buy another but don´t accept my credit card details, why?

    I've bought books and now want to buy another but don´t accept my credit card details, why?

    Nobody here could possibly know why your credit card is not being accepted. We don't work for Apple, we are just other users voulnteering out time to help.
    Did you get any message from when you attempted to make the purchase? Did you review your credit card details in your iTunes account? Did your crest card expire and you forgot about it?

    Hi Fayet16,
    Please quit the Creative Cloud desktop application by clicking the settings options and select Quit. Then please follow the following steps:
    Go to C:\Users\[UserName]\AppData\Local\Adobe and rename the folders "AAMUpdater" and "OOBE",
    Then go to C:\Program Files (x86)\Common Files\Adobe and rename "OOBE" folder.

  • How do I buy OSX Lion?  Can't Seem to Find a Way

    I have an old MacBook (pre-unibody).  I upgraded to Snow Lepoard and was going to upgrade to Mountain Lion, but my system won't support it.  I can do just Lion, but can't seem to find anywhere to buy it.  I'm trying to get to the cloud.  Help....

    If you need to purchase Lion call 1-800-692-7753 or 1-800-676-2775. Ask for a Sales Representative. They will check your Apple ID, and email you a code and instructions.  The cost is $29.99 (as it was before) plus tax.  It's a download.

  • Installed Lion OS 10.7.2 and now Zip Drive 100 will not open

    Using iMac Intel in only Apple mode. Zip Drive 100 connected to USB
    Thank you for your replies to my Zip Drive question. I too cannot understand what happened. Up until I upgraded to Lion OS 10.7.2, I was able to use  my 100 Zip Drive. Now it will not open any of these Zip disks. The Zip takes the disk, green light goes on but it never registers on the desktop nor opens up

    Up until I upgraded to Lion OS 10.7.2, I was able to use  my 100 Zip Drive.
    But what were you running before you upgraded? I'd say your problem is that you don't have any Zip Drivers that are compatible with Mac OS X 10.7. If they even exist, you'd find them on the Iomega site. But the last ones they have are for 10.3 and 10.4, so that doesn't bode well for any support.
    If I were you, I'd post a question in the Iomega Support forums about this problem and whether or not (and how) you can get your Zip drive to work on 10.7.

    I installed Maverick and now nothing happens when I click on the Safari icon. Can this be fixed?

    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

  • I updated the operating system on my Mac book and now I can't sync my Mac calendar to my iPhone 5. How do I fix this? No where in iTunes now do I see to sync my calendars...

    I updated the OS on my Macbook pro and now I can't sync the calender to my iphone...it no lonver gives me the option. What happened?

    OS X Mavericks takes away the ability for calendar/contacts syncing through the computer. You'll have to use iCloud, or manually type them in.

  • Created a book and now want to bring in other images to the strip below.

    I have created my draft book but I found 25 images were missing from the file I created the book from so I now want to bring in those images which are on a memory stick.  I tried importing and they are in a separate file in the catalog.  I can't seem to get those over into the file related to the book.  How should I proceed? move the images from that file to the books file or reimport them into the books file and MOST importantly how do I do it since I have obviously been unable (my failings) to make it happen
    Thanks
    Jim

    Thanks for looking at this.  I realize my novice nature and lack of the wrong vocabulary so lets ask it this way and I know this is a real basic question.  I have a collection that is embodied in the saved book.  and I can see it in collections with the book icon.  I have a memory stick to import from.  What is the process, because when I went to import these I did not see that collection in the list of target  locations for the import.  Best procedure to import more into the existing collection?
    Thanks for putting up with my uneducated attempts, I will be working on betting better
