    Hey,

    I'm planning to update my OS on my late 2011 MBP.

    I currently have Mac OS X Version 10.7.4

    I will be buying/downloading ML today and have some questions.

    • Is ML anyway buggy or is it stable.
    • Is it easy upgrade from 1 to the other
    • How is it done, I've never update OS on a mac before.
    • I have my HD partitioned so can i install new ML over existing Lion in that partition fresh or does it leave files/software.
    • Any other info anyone thinks I should know


    Thanks in advance.

    stable
    yes v easy
    go to the app store and buy it there.
    ML will by default do an upgrade install and keep your apps data and settings.

    Can you do a fresh install on my OS partition to get rid of apps and files?

    Thanks Charlie, I'l try this now.

    ----------

    If I have an app downloaded from app store such as a game, if I do a clean install, can I redownload the app from store without charge?

    As I follow the usb steps:
    • Download OS X Mountain Lion and Extract the DMG File
    • Download OS X 10.8 Mountain Lion from the App Store
    • Go to the /Applications/ directory and right-click on “Install Mac OS X Mountain Lion.app” selecting “Show Package Contents”
    • Open the “Contents” directory and then open “SharedSupport”, looking for a file named “InstallESD.dmg”
    • Double-click on InstallESD.dmg to mount it on the desktop
    Double-click on InstallESD.dmg to mount it on the desktop is where I receive an error..

    use this small app instead of making the usb bootable the manual way it will make it easier for you

    Thanks, I'll try this after work.

    Is there anyway I can download my SAFARI and FIREFOX bookmarks?

    So i can save them to partition as I'm doing a fresh install.

    im not 100% sure but I imagine you can save your bookmarks to a usb drive or something then import them back in after your clean install

    Install failed

    Ok installation failed.

    Can anyone please help me as to why?

    My MBP - LATE 2011 10.7.4

    • I formatted my 8gb usb to Mac OS extended (journaled)
    • I downloaded LionDiskMaker tool, and ran it, selected Mountain Lion dmg which I bought earlier.
    • That took about 30minutes to go onto USB stick.
    • So now I can see USB stick mounted on left and I can see this image below(so it looks fine to me)
      [​IMG]
    • I restarted my MBP and held down option key, the selection came up and I clicked the orange USB on the right.
    • It gave me option where to install it, I selected fresh over the current MAC install as I have all my documents saved on a partition of the drive.
    • It installed for 70% and then gave me error couldnt finish install because couldnt find files or something of the sort.

    Why is this happening? Is it not straight forward.
    I'd be very grateful if someone could help me.

    there was a time when i got "cant install additional components" error when install OSX is this the error you got?

    for me it was found out it was due to bad RAM

    use MEMTEST to test your RAM

    if you no longer have OSX installed and cant run that test, but have other RAM i would try that

    based on your screenshot it looks like your USB was made successfully

    'Can't download additional components needed to install OS X'

    So I have an uptodate Lion 10.7.4
    Ram is 4gb, tested with MemTest - No Errors
    I verified the disk I'm trying to install on and all is ok there too.

    I created a partition to add all my files in there and the plan was to boot via USB and overwrite the original Lion install, so i assume it would be correct?

    Update: I downloaded ML again. This time when i click show contents it DIDmount. Where it didn't with previous download.

    I'm currently writing ML to USB, and it will be another half an hour before I restart and try Install.


    Progress though, at least.

    Before going any further I would suggest a backup to an external drive.

    Just because you may or may not have to end up doing a clean install.
    Also I have come to find out that while updating over the current OS works most of the time and things work perfectly, sometimes you get little "gremlins" that are super hard to find and fix.
    Generally a clean install makes life easier in the long run, think of updating your OS like updating your house with new paint and floors while leaving all of the furniture.


    I'll just cover my usual process.

    If you do not have tons of apps then this will be rather easy.

    In Finder, on the lower left side, go down to devices. You should see the name of your hard drive listed. Click it and then users, which you should then see your Home Folder. The Icon will be of a house.

    Unless you've saved files in specific places your Home Folder will house all of your Documents, Music, Downloads, Desktop files, Music, Pictures and Movies.

    Just drag your home folder to a backup drive.


    If you have an iCloud account, then your Mail, Contacts, Calendars, Safari Bookmarks will also be backed up.
    If you decide to clean install just sign back into iCloud during the install process and all of this info should be downloaded back immediately.
    You can find it in System Preferences->iCloud and just make sure you have all of the options you wanted saved to be checked.

    Also you asked about your apps, if you have purchased all of them through the Mac App Store then all you have to do is sign back in after a clean install and go to the purchased tab and all of the apps tied to your account are available to you again.

    If updating you must update to the most recent version of Lion and THEN update to Mountain Lion.
    You do the update from within Lion
    With a clean install you are starting fresh with ML.

    It sounds like you have a good bootable USB copy of Lion ready to go so I'll start with a fresh install steps.

    Make sure your USB is plugged into your computer and connect the power supply if you're on battery power.

    You can hold down the power button at this point to shut the computer down because we aren't worried if OS X shuts down on it's own... we're starting fresh :)

    Turn the machine back on and hold down the Option key immediately after the chime or grey screen appears, continue holding Option until the bootable drives appear and select your USB drive from the list.

    Once in, select Disk Utility from the menu shown.(How I usually format) I select my hard drive from the left side menu in disk utility, not the named "Macintosh HD" partition but the HDD.
    Click the partition tab on the right side and under partition layout, select 1 Partition ( or as many as you want ) and then name your drive whatever you would like. Format type should be the default OS Ext Journaled. Click Apply and it should be done within a few seconds.

    Breathe deep, you just deleted everything, if it's backed up you're all good. :p

    Close disk utility and Select to reinstall OSX and just follow along until the installation parts starts.

    You can walk away and do laundry or make a sandwich at this point because it is going to take a while.

    Once ML boots up for the first time it will ask you for a little bit of information such as your Apple ID and iCloud account so that it can pull all of your information and bookmarks.

    Once on your desktop I would open two Finder Windows.
    For me it makes it easier to drag and drop my files back to where they need to go.
    If you have this Nifty little app called Cinch, it basically gives your Mac the "Windows Snap" functionality. Where you can drag a window all the way to the left side of your screen and release and that window will take up the left half of your screen, same for the right, drag to the top of the screen and the window full screens without you having to manually resize the window.

    You should basically be done at this point other than reinstalling apps.


    You could also use an external as a Time Machine backup and do a fresh install from your USB drive then restore from the backup once you are in ML but every once in a while I've found those "gremlins" using this method as well.

    Your best bet if you choose to take the plunge is do your fresh install, make sure you have everything installed the way you like it and then do a Time Machine backup from that point on.

    This makes it less hectic if there is ever a next time and you know your backup is for the most part a clean backup.

    Finally worked, thanks to all who helped.
    Happy now with the new ML.

    Safari much better than it was previously too :)
