  • Can you uninstall lion 10.7?

    Lion 10.7 is not supported by my university (wasnt aware) and now I can't use the wireless printing function.

    You can uninstall Lion by using the upgrade Snow Leopard disc or original OSX Install disc that came with your system. Remember to do a clean install (Erase the disk) of the older OS as you will be installing an earlier version of Mac OS X.
    EDIT: To reinstall an older version of OSX just do the following:
    Shut Down your Mac.
    Push the power button to turn it back on.
    Hold the "option" key.
    Insert your earlier OSX install disc.
    The disc should appear on the screen, select it using the keyboard arrow keys.
    Once the disc is selected hit the "Return" key.
    The disc should load.

  • My mac keeps freezing...How can I uninstall lion?

    My mac keeps freezing on me, particularly when Im on safari. The most annoying part is that it happens three or four times in a matter of an hour, and then Im prompted to submit a report that feels like a joke considering that we have yet to see an update for lion solving this issue, and the problem persists. How can I uninstall lion and get macs previous iOS back?

    Downgrade Lion to Snow Leopard
    1.  Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

  • Can you control Lion on your desktop with an iPhone?

    Can you control Lion on your desktop with an iPhone?  I do not want to buy a wireless trackpad.  Who needs all those batteries?  Hoepfully the iPhone can control it in the meantime, and then they need to make wired trackpads.

    If confused, people generally ask in the forums.

  • How does QuickTime 10 go to pro? Can you uninstall it and put QuickTime 7 in it's place?

    You can't upgrade QuickTime 10 to pro (yet). Can you uninstall 10 and install QuickTime 7 in OSX 10.6.8 so it can be upgraded to pro?

    Can you uninstall 10 and install QuickTime 7 in OSX 10.6.8 so it can be upgraded to pro?
    You could, but why bother? QT X and QT 7 Pro can both simultaneously co-exist under Snow Leopard OS.  Simply install QT 7.6.6 for OS 10.6.3 and later which is available HERE.

  • Can you download Lion and place on two devices?

    I have an Imac and macbook - can you downloas Lion and transfer / copy to both machines?
    Many thanks, G

    Yes. You must have Snow Leopard 10.6.8 installed on each so you can purchase and download it. You can then re-download on the other computer without having to pay for it a second time. Or you can do the following:
    Make Your Own Lion Installer
    1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
    2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
    4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
    Open Disk Utility.
    Select the USB flash drive from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
    Drag the InstallESD.dmg disc image file into the Source entry field.
    Double-check you got it right, then click on the Restore button.
    When the clone is completed you have a fully bootable Lion installer that  you can use without having to re-download Lion.

  • Can you buy Lion with a iTunes card?

    Can you buy Lion with a iTunes card?

    Yes. Apple's iTunes, App store, iBookstore and Mac App store all accept credit cards, Paypal and Apple's itunes cards. On the side of the app store, it says account. below it says redeem, there is where you would enter the iTunes cards code and press enter. after that, ENJOY LION!!!!!!!

  • How can I uninstall Lion?

    I'm getting a window saying the installation has failed, that I should reinstall Lion.  How can I uninstall it?

    And this link for How to create Lion Recovery Drive just went MIA / "404"

    You can also use the OS X Lion installer from the Mac App Store to create an external bootable drive, complete with a Recovery HD partition. See this article for more details. This approach will, at least, create a bootable drive with Recovery HD which you can carry with you in case you need to use Internet Restore or make use of the other utilities Recovery HD provides.

  • How many computers can you install Lion after purchasing from App store. My wife and I have our own Apple ID will it accept 2 different ID

    I have a MacBook Pro and an iMac . My wife has a MacBook and an iMac. How many computers are you allowed to install from one download. We both use Apple products and have our own Apple ID. Can I download Lion on her computers after I have both of mine installed? Or does she have to buy LION again using her Apple ID# ?

    A single purchase of Lion will allow you to download it multiple times as long as you use your Apple ID.
    If your wife wishes to install Lion, she must sign into the App Store with your Apple ID.

  • Can i uninstall Lion

    i have installed Lion and having too many issues.
    have tried to re-install OS X from CD but computer won't allow it.
    any ideas how i can un-install Lion for now?

    Do you have a backup of your iMac?
    You will need to wipe your drive and install Snow Leopard and then restore your settings, applications and data from your backup, either from a clone or Time Machine.

  • Why can you uninstall things when they're still running?

    I'm aware that apps run in RAM, but what happens if you uninstall an app while it's running and then select an option it that would make it change one of its config files... would it then crash? Or would the file (assuming you have permissions) be rewritten, and left as a remnant when you close the now-deleted program?

    Komodo wrote:Because it seems like a fairly major issue that your system undergoes meltdown if something's in use when it's being updated. There really ought to be some sort of check for what's running at the time of update...
    Hmm, well, it rarely has the potential to happen - mine wasn't caused by cron, but by a screen status script, and even then it only caused problems because I was running pacman inside screen.  If I had been running pacman in it's own terminal, yes, screen would have crashed, but pacman would not have.
    Also, I don't think it's entirely the dev's jobs to prevent users from screwing things up in an update.  I mean, if you want it as safe as possible, we can always go the windows route: "Please reboot now, updates will continue when you reboot" and fully upgrade things via init or something dumb.
    I haven't put alot of thought into this, but basically, as long as the terminal you're running pacman in does not crash, it will be fine... I'll try and see if there's any straight forward ways to make sure things are really secure and all, but I'd rather not have to take control over a user machine while upgrading...

  • How many computers can you download Lion to?

  • Can you run Lion os and Lion Server os on the same Mac mini?

    I'm a windows convert to Mac and I'm interested in running a standard Lion Client, but at the same time running Lion Server on the same Mac Mini (Server Edition).  My needs for the Lion Server OS is to handle e-mail, a Web Site, and file sharing between the server to a secondary PC, iPad, and iPhone.  But at the same time I wish to dive into the Mac (Apple) experience.  I just wish to be able to do this on the same machine.
    As a secondary question, is it possible to merge two different iTune Accounts into one?  Is it possible to share items purchased on one iTunes account with an iPad that is tied to a different iTunes Account?

    1. Yes, but you'll need separate partitions for each OS, or run the client OS in emulation.
    2. It isn't possible to combine the accounts, but a single iTunes library can contain content from multiple iTunes Store accounts.
