While installing Lion my Bluetooth module disappeared. How can I reinstall it?

You ought to get a dialog asking to install the first time you run an app that needs it
Details here:
http://www.macworld.com/article/1167855/installing_mountain_lion_what_you_need_t o_know.html
The relevant bit is this:
Note that the first time you try to load a webpage or run an app that requires Java, Mountain Lion will prompt you to download and install the Java runtime, even if you upgraded from Snow Leopard or Lion and you’d previously installed Java. This is normal—you shouldn’t worry that installing Mountain Lion somehow “lost” any of your data or apps.
Or you can go to the Apple Downloads page and search for Java

    If all your files are missing
    You may have logged in as a different user, such as Guest. Open the Users & Groups pane in System Preferences. Your name should be at the top of the user list, under Current User. See also this support article.   
    If files are missing from one folder
    Change the Finder view mode; for example, from icon view to list view, or vice versa.

  • I own two i macs. I bought and installed Lion on one computer. How can I install Lion on the other computer without additional charge?

    I own two I macs. I bought and installed Lion on one computer. How can I install Lion on the other compute without additional charge?

    If it's the same email address Apple registration on both, use the 2nd computer and go to the App Store and find Lion. If different, use the second computer but log in to the App store with the address you used on the first go round. The buy button should instead say install. Then go through the same process again.

  • My Eye Dropper STILL does not work in CS5 while using Lion with one monitor. How can i fix this?!?

    Hello everyone!
    This is my first post because i have grown very disgruntled at the fact that my eye dropper does not work my Premiere CS5. I would use the Ultra Key a lot but now I obviously can not really use it too well because of no eye dropper. I saw that this problem existed after the Lion update but this really should have been fixed by now. I am using only one monitor also. Is there a way to fix this or is this still known to be broken? I paid good money for CS5 and would be very upset if the only way around this is to pay MORE money to upgrade to CS5.5. Thanks.

    Thanks for the response Stephen! I find this very bad on Adobe's part though if they do not feel obligated to fix CS5 for Lion. Eye dropper is a major part of Premiere and i am going to be very dissapointed if they do not fix that. With the amount of money the Suite costs, they definitly should make sure it runs well for quite a few years. I would expect a copy of CS4 to be able to work too. If they do not fix CS5 all because the OS has changed basically tells me that every 2 years or so, they stop caring about their product.
    Sorry i sound so bitter about this but it has really hurt my workflow. Ultra key is great and something that FCP does not have so it has the edge in that respect, but now i can not even properly use it. I have to go into After Effects with the same clip, use that eyedropper to get the correct color # and then copy and paste the # into Ultra Key in Premiere which is very very annoying and slows down my system quite a bit.
    So basically, they are probably not going to ever fix this? Thanks again

  • Address Book app disappeared; how can I reinstall it?

    Out of the blue, my Address Book app disappeared. The icon in the Dock has a question mark on it, and the application itself is no longer in my Applications folder, or anywhere on the drive. Even stranger, it's not in any of my Time Machine backups, even though it was working and present until yesterday.
    Mind you, I'm not talking about the data. it's that the app itself is gone. Interestingly, my email still seems to act as if the Address Book contact information is still present. But if I select an address in an email "from" field, for example, and say "Open in Address Book," nothing happens.
    Now here's an even weirder part. I also have a recent backup of my Apple Mail and Address Book using Email Backup Pro. After seeing that the Address Book app seems to have also disappeared from my Time Machine backups, I opened Email backup Pro and did a restore of my Address Book. The program reported that the Address Book was successfully restored, but nothing changed -- the Address Book app was still nowhere to be found. I've done this twice.
    I also have my Address Book data on my iPod Touch (thankfully). Synching does nothing -- nothing changes on the iPod or on the hard disk, in terms of Address Book.
    I'm baffled. Although I'd like to know what caused this, my more immediate concern is to get a functioning Address Book installed again. I booted from the Snow Leopard disc, but could see no option to install just the Address Book.
    Does anyone have any ideas?
    Thanks, John.

  • IPhoto disappeared, how can I reinstall it?

    MacBook Pro
    OSX 10.8.2
    I just got this Pro yesterday. Anyhow, I screwed up when I was trying to move some old files from a Time Machine backup on my old iMac so I reinstalled OSX according to Apple's instructions (Cmd/R). It took all night but all looked well. I then copied the files I need from the iMac onto a hard drive, plugged it into my new Pro and copied them over. Everything worked fine until I went to try iPhoto. It was gone! I've searched for the iPhoto app with Spotlight and no dice. I folled some instructions I found here (reindix) - still no dice.
    This Pro does not have a CD drive not did it come with a USB dongle. How do I get the iPhoto application back? Thanks.

    download and install from the App store - you log in with the Apple ID that you set the computer up with - you may need to accept the App first

  • HT1544 how can I reinstall the Mac OS X from scratch?

    I have an early 2008 iMac that came with Mac OS X 10.5 leopard. I have bought all os's since then, and Today I am using the most recent one, mountain lion. My question is, how can I reinstall the Mac OS X from scratch? Is there a quick way ? Or do I have to:
    Find the leopard CDs that came with the iMac
    And go through the cd installation.
    Then, can I jump from leopard to mountain lion?

    If your goal is to just reinstall Mountain Lion, you can restart the computer holding the Command and R keys, then choose the reinstall OS X option from the utilities choices presented to you.
    That restarts the computer using the recovery hard drive that was created when you installed Mountain Lion...but note you must have an internet connection when you do this reinstall.

    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet
                if possible because it is three times faster than wireless.

  • I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

    I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

    It's best to install Snow Leopard on one of the three remain drives without an Operating System.
    You can then install the applications you need from the original media. Create a User Account using Setup Assistant.
    Do you want to migrate User Accounts from the OSX LIon boot drive, or are you keeping the User Accounts separate?
    Dual-booting just requires holding the option key during startup and selecting either Lion or Snow Leopard.

    I purchased and installed Lion on my iMac. How do I install it on my MacBook without paying for it again?

    You'll have to download again.  You will not be charged if you use the same Apple ID.
    Save the file somewhere before installing.

    Use the Flash Drive that came with your computer it has Snow Leopard installed on it. If you lost it or cannot find it then call Apple and they will replace it for you, I don't know how much they will charge.
    BTW when installing MS Windows please follow the directions whether you are using Boot Camp or a vitualialization solution (Parallels, Fusion, etc.) had  you done this you would not have had any issues.

  • I purchased my macbook pro with Lion pre-installed. However its not showing as "installed" from the app store. How can I re-install?

    As the title says, I just bought my macbook pro. I'd like to reinstall Lion. However its not showing as "installed" in my app store? So How can I reinstall it?

    No. Launch the Terminal 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.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
    Drag or copy — do not type — the following line into the Terminal window, then press return:
    diskutil list
    Post any lines of output that appear below what you entered — the text, please, not a screenshot.
