Need to reinstall Mac OS after lion update, how to?

Hello guys,
I recently brought my MBP 15" and imediatly downloaded Mac OS X Lion via apple store, but I after sometime I realized that screwed up some settings during initial setup. Now I need to reinstall(format) my current OS to fix what I've done.
First question: Is there a way to change those initial setup settings (like MAC-pc name) without formating it?
Second question: if not, will I need to buy Mac Lion again to reinstall it? (cause, as far as I know, there's no such thing as a Retail Lion DVD on stores)??
Third question: How should I procede to format my current OS? Cause I got only a snow leopard Retail DVD and the restoration DVD that came with the MBP box. Unfortunately, both are not working to restore a Mac Lion OS.
I kinda know what I'll have to do: Format with Snow Leopards DVD and then download Lion via Apple store again, but I'm just wondering if there's anyother possibilities.
Thank you for your time guys. bb

Changing your computer name is trivial and does not require a re-install.  In fact, almost nothing requires a re-install.  The only thing I can think of would be if you need to reformat the partition for some reason.
Go to System Preferences
Go to Sharing
Make sure the lock at the bottom left is unlocked
Enter new computer name at the top
That's it!
You definitely do not need to re-install snow leopard ever again, even if you do decide you need a Lion redo.  Just boot your machine while holding Command-R.  You will get a Recovery Install option.

    well PhillyPhan, I can't tell that you're better looking just by your iphoto icon, now can I? Although it is a lovely sunset you've got there.
    Thanks for your response to my question, I see your point and will do that, however, I have another folder that was created before I had a Mac, which has all sorts of lovely titles and labels and some of those pictures I brought over to my ibook when I first started. So there are some duplicates in my iphoto library that I already have backed up in that other folder. I guess I shouldn't really obsess about those. I guess I am just nervous about deleting all my prior iphoto library, but I should have faith that it will all be there in my pictures library. Just trying to clean up the virtual mess.
    I'll hold my breath and take the plunge.
    Thanks!

  • What update do I need to get Mac OS X Lion 10.7.5 (11G63b) to run Apple TV?

    What update do I need to get Mac OS X Lion 10.7.5 (11G63b) to run Apple TV? I have been told its about $19.95 aus can someone please give me a link so I can  get the correct update to run the Apple Tv through my Mac
    Thanks

    No update is going to make a computer "run" AppleTV.
    If you are referring to using AirPlay Mirroring to display the Mac on the AppleTV, that requires OSX 10.8 or higher.
    Requirements for AirPlay in OS X
    An Apple TV;
    Apple TV (2nd or 3rd generation) with software update v5.0 or later. See How to update Apple TV software.
    Airplay turned on in the Settings menu of the Apple TV.
    A supported Mac
    AirPlay Mirroring in OS X takes advantage of the hardware capabilities of recent Macs to deliver high frame rates while maintaining optimal system performance. The following Mac models support AirPlay Mirroring::
    iMac (Mid 2011 or newer)
    Mac mini (Mid 2011 or newer)
    MacBook Air (Mid 2011 or newer)
    MacBook Pro (Early 2011 or newer)

  • HT4711 how do I get iPhoto back after reinstalling mac os x lion?

    I lost Iphoto app after I reinstalled  mac os x lion, and cant get it back.....any suggestions?

    iPhoto is not part of the OS X installation. It's a separate app.
    Log in to the App Store and download it again - it doesn’t require a purchase.

  • Reinstalling Mac OS X Lion from Recovery problem

    So I've decided to sell my 2007 Macbook (Black) to someone else, but when I tried to
    wipe it (I already did it successfully) and reinstall Mac OS X Lion, it comes up with
    "This item is temporarily unavailable. Please try again later"
    It happened today, I'll try again tomorrow since it says "Please try again later"
    but I need a quick solution because I need the money! Help please!

    If you plan to sell or give away this computer, then you must install the original version of OS X that it came with pre-installed. That was 10.4.9 or 10.5 depending upon which model you have. Get out the installer discs that came with the computer and use them to erase the disk and install a fresh copy of OS X. Or you can do the same using the retail Snow Leopard DVD.
    Clean Install of OS X
         1. Boot the computer using the OS X Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. 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.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Before it restarts just shut it down.
    Be sure you also de-authorize the computer and sign out of your iCloud account.

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

  • Is it possible to reinstall Mac OS X Lion on MacBook and then use Time Machine to restore to the previous backup I made before reinstalling Mac OS X Lion?

    Is it possible to reinstall Mac OS X Lion on MacBook and then use Time Machine to restore to the previous backup I made before reinstalling Mac OS X Lion?

    My MacBook was not normally booting up. It would turn on, make the Apple startup noise, and the bottom loading bar would progress just a little bit, then my MacBook would shut down. I tried rebooting it many times and the same thing would happen, it would just shut down. Then, I read that I can reset the PRAM (by holding Option+Command+P+R after the Apple startup noise comes). That worked, but now I get a screen that asks me to choose one of the 4 options (see:  http://images.macworld.com/images/article/2012/07/lionrecoveryutilities-289404.j pg). I choose Restore From Time Machine Backup, but it progresses to 17.6% and gets stuck there forever. I tried doing it again, and it got stuck at 17.6% again. That is why I am asking if I should just reinstall Lion, then restore a previous backup on the fresh new Lion?

  • Why won't my Mac with Mt Lion update my calendar and address book through iCloud

    Why won't my Mac w Mt Lion update mt Calendar and Address book through the Icloud?

    Are you really still running Snow Leopard (10.6.8) as shown in your profile? If so, that's why. Full use of iCloud needs at least Lion 10.7.2 or Mountain Lion.
    If you have upgraded to Mountain Lion and forgot to update your profile, here are some things to check:
    Is it on a network?
    Is it signed into iCloud? The same iCloud Account?
    Are Contacts and "Calendars & Reminders" checked in the iCloud and same account's "Mail, Contacts & Calendars" panels of System Preferences?
    Are you looking at the correct accounts in Calendar and Contacts?

  • Can't download the additional components needed to install mac os x lion

    I recently upgraded the RAM in my MacBook Pro (13-inch, Early 2011) to 16gigs.  The process went smooth at first.  Then the Computer would not boot and stayed on the white Apple screen with the circle spinning. A progress bar would appear and disapear but it would never get past that screen.  I tried to fix that but ended up backing up my hard drive and now I am attempting to restore the unit using "command + R" at startup.  I have eraseed and reformated the drive using with Disk Utilities OSX extend journaled. Then I attempt to reinstall and the unit is connected to my wifi which is fast and stable and I get, "can't download the additional components needed to install mac os x lion."    I have tried this many times

    I still have the 16gigs of ram in the macbook pro which I am told this unit supports both by OWC (which is where i bought it) both identical 2x8gig sticks ddr3 1333

  • After LION update web Cam is no longer being detected at all. Does anyone have a fix? Thank you

    Thank you, Rod!
    While researching frame rate I came across this helpful blog posting: Crazy about Captivate: Lessons Learned: Video and Resolution in Adobe Captivate
    This is the line that caught my attention: "I discovered, after several experiments, that if you publish a course in Captivate as SCALABLE with a video inserted, no matter what the resolution, it makes the video look pixelated."
    When I unclick the "scalable HTML content" button before publishing, the video is fine!
    Big sigh of relief! Now I just need to figure out why audio won't play on one of the slides (it has an accordian widget, if that's relevant) and why I can no longer use Effects (I get the message, "Effect file is not valid")

  • Do i need to purcahse Mac OS X Lion again?

    Hi,
    I have been using Mac mini in my office since last 3 years and last year i purchased Macbook Pro for myself. Last month when OS X Lion was released i upgraded my OS X to LION. Soon later after few days i found that my MBP was not working, after showing it to engineers at iStore they said that the Logic board is faulty and need to be replaced, since it was under warranty i was not worried but soon i realized that What about the apps i purchased which include Mac OS X Lion too, but the engineer said it won't be affected. But then i have a doubt, what if my Hard disk was faulty/crashed and needed to replace with new, do i need to purchase Mac OS X Lion again?

    no,
    what you do is on the app store it is under purchased, but you shouldnt have to do that

    No. Updating to Lion should not have any effect on your Windows partition. However, I would backup everything first just in case.

  • Reinstall Mac OS X Lion with saving data

    Removing and rebuilding a malfunctioning Recovery HD partition « Der Flounder
    By the way it is NOT self deleting. Something deleted it, you or something else.
    Just to check open Terminal and type diskutil list then hit the enter key. If there is an entry for "Apple_Boot Recovery HD" of 650MBs then you do have a recovery HD partition.
    Once you recreate the Recovery HD I would do one of 2 things, or both of them.
    1) Use the Lion Recovery Disk Assistant to create a USB thumb drive of the recovery HD file. that way you will always have a way to boot your Mac and do maintenance or Reinstall Lion.
    2) follow this link

    If you do # 2 you can forget about # 1. But me being me I have both.
