Is it possible to remive Mavericks from my iMac?

Since I have Mavericks, I can't use my HP Photosmart D110 scan. And I need it! I just would dlike to go back to my old OS...

Reinstall fro the backup you made before you chose to install Mavericks, then follow
OS X Mavericks: Revert to a previous OS X version

  • Installing Mavericks from Leopard

    I have an iMac (Intel) 2012 that came with Leopard already installed. I would like to format and and install Mavericks. I have the original Leopard DVD and I ask: is it possible to install Mavericks from Leopard? How do I do that?

    Check which OS you have installed. I would think a 2012 Mac would have shipped with Snow Leopard (10.6).
    If you really have Leopard (10.5) you'll need to purchase the Snow Leopard DVD from the Apple Retail Store:
    http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
    If you have Snow Leopard, use Software Update to bring it up to 10.6.8, then open the App Store from the Apple Menu. From there, "purchase" Mavericks (it's free).
    Backing up a little, if you do have Leopard installed that came with your iMac, please go to About this Mac in the Apple Menu, then click More Info...
    Under the Hardware section, note what the model identifier is and post it here.
    Also, you should look at what software you have installed that may not work with Mavericks.

  • I recently upgraded to Mavericks from Snow Leopard. Does Snow Leopard still exist on my Mac? If so, is it possible to restart under Snow Leopard in order to run PowerPC apps? If not, is there an OS available in 64 bit that supports PowerPC apps? Mav ***.

    I recently upgraded to Mavericks from Snow Leopard. Does Snow Leopard still exist on my Mac? If so, is it possible to restart under Snow Leopard in order to run PowerPC apps? If not, is there an OS available in 64 bit that supports PowerPC apps? Mav ***.

    The only reason I upgraded to Mavericks was because my Snow Leopard OS was 32 bit, which I was told would support only 4GB of RAM.
    That wasn't quite right. You can put in as much RAM as your Mac's hardware supports. The division is in the apps themselves. A 32 bit app can't use more than 4 GB or RAM. A 64 bit app can use much more.
    For example, as a 32 bit only version, Photoshop CS3 can't use more 4GB of RAM, no matter how much you actually have installed. CS4 or later can use all the RAM you want to throw at it.

  • HT201232 Is it possible to convert to Mavericks from Yosemite without a Mavericks backup?

    I have a 2011 MacBook Pro and recently downloaded Yosemite. Turns out this was a horrible idea and my computer cannot handle the new software properly. I want to revert back to Mavericks, which was running wonderfully with few issues. I have not done a backup, and just ordered an external hard drive to use Time Machine with. I was wondering if it is possible for me to revert to Mavericks if I only have backups of the current Yosemite files/settings. I am not worried about keeping apps and their data (the most important stuff is in iCloud) but am more focused on my files, which I know I can back up to the external hard drive. I want to know if I can actually revert to Mavericks without killing my computer. I'm a recent college grad and don't have a spare $2500 laying around to spend on a new computer, which would be the ideal fix (it's been slow for a while anyways). Help please!

    If you have no TM backup with Mavericks but you updated to Mavericks from say Mountain Lion then go to the app store under purchases and see if it will show Mavericks.  You may be able to download and install.  Be sure to save your files first. You could do an internet recovery (command-option-R) boot and it will install what came with your Mac (e.g. ML) then you can then update to Mavericks from the your purchases it it shows up there.

  • Untangling Mavericks from iCloud

    I recently updated our Macs from Snow Leopard (10.6.8) to Mavericks (10.9.x). We had skipped Lion and Mountain Lion due to their heavy iCloud entanglement. iCloud syncing is a handy tool for on-the-go metropolitans with high bandwidth, symmetrical internet access and/or abundant free WiFi locations. But for those of us who live in the country, with our only choice being low bandwidth asymmetrical (often capped) internet access, iCloud syncing of photo streams and data is a cruel, have-vs-have-not, joke. Besides, I’ve never thought it was all that clever to share/sync files, calendars, contacts, notes between two Macs attached to the same private WiFi network by pushing the data to/from the cloud.
    So as soon as I did the clean install of Mavericks, I began looking for how to untangle Mavericks (and iOS 7) from iCloud. The following tables summarize what I did. If anyone is interested in the details, just ask.
    Minimize iCloud Entanglement in OS X
    iMac & MacBook Pro
    Internet Accounts
    Turn off iCloud sharing (except Mail)
      Sync Mail
    Use IMAP Mail servers (iCloud & gmail)
    Sharing/Syncing (local network only)
    Install OS X server and set up...
      Files
    File Sharing
      Calendar
    CalDav
      Contacts
    CardDav
      Notes
    Mail server (used only for Notes)
    Sharing/Syncing (via iCloud)
      Photos
    Limited use of small Shared Photo Streams*
    Apple’s “iCloud” Applications:
    (e.g. TextEdit, Preview,…)
      Open/save dialogs
    Turn off iCloud saving in iCloud sys pref
      Missing menu item for “Save As…”
    Add keyboard shortcut (shift-command-s)
    Minimize iCloud Entanglement in iOS
    iPad Mini & iPhone 5s
    Sync Mail
    Use IMAP Mail servers (as above)
    Sharing/Syncing (local network only)
      Calendars, Contacts, Notes
    Use local OSX server (as above)
    Sharing/Syncing (via iCloud)
      Photos
    Limited use of small Shared Photo Streams*
    Backups
    Manually backup to Macs
    *Apple’s existing iOS tools (Photos and iPhoto) for organizing photos into albums and then syncing them with Macs are pitifully inadequate. For us, the simplest method is to build an album on a Mac in iPhoto and share it with our other Mac and iOS devices via a Shared Photo Stream. Even this limited use of the iCloud has drawbacks. Like when we brought the new iPhone 5s home and it brought our internet connection to it’s knees for several hours while downloading the Shared Photo Streams in the background.
    —GetRealBro

    The reasons to untangle Mavericks from the clouds fall into two main categories:
    Practical - reduced use of iCloud services which can use considerable bandwidth (e.g. Photo Streams) and/or use bandwidth at inconvenient  times (e.g. App Store update downloads in the background).
    Several items are quick and easy settings within Mavericks/iOS 7 which address the more “practical” aspects.
    Photo Streams - If you take a lot of photos and have several iOS and OS X devices, My Photo Streams can be a serious bandwidth hog. You can turn them off in OSX - iPhoto>Preferences>iCloud and iOS Settings>iCloud.>Photos
    App store background updates - You can’t reduce the bandwidth required to download the updates. But you can control WHEN that bandwidth is used by setting the App Store preferences which are found in….  System Preferences.
    iOS Backups - You can reduce the bandwidth required to backup your iOS devices to the iCloud by adjusting which items are backed up to iCloud - Settings>iCloud>Storage & Backup>Manage Storage>[pick your iOS device]. Then periodically backup your iOS devices manually in iTunes.
    Apple’s “iCloud Apps” (e.g. Textedit, Preview, iMovie, iWorks apps etc) - in OSX you can turn off storing/syncing via iCloud by adjusting the settings in…. System Preferences>iCloud>Documents & Data. In iOS you adjust these in Settings>[scroll to the application name]>Use iCloud
    Philosophical - replacing iCloud services (e.g. syncing/sharing of Contacts, Calendars, Notes, etc.) with local services to enhance privacy and possibly improve performance, depending on internet bandwidth / caps.
    Here are some things to consider before replacing iCloud services with local ones provided by OSXServer.
    Setting up an OSXserver to share/sync Calendars, Contacts, Notes, etc. will not dramatically reduce your internet bandwidth.
    The key component OSXserver costs $20 and requires a Mac that is running 24/7/365 (e.g. a headless Mac Mini). OSxserver does NOT require a dedicated Mac. It can run on a “users” Mac (e.g. an iMac). But that user has to be mindful to not disrupt services with frequent/unannounced Restarts (e.g. as required by some software updates).
    The local shared services (syncing contacts/calendar, file sharing, etc.) only work when you are connected to your local WiFi network. For example, if you add a Contact, make a Note or add a Calendar item on your iPhone while at the dentist, they will not get synced to your Mac/iPad until you get back home.
    Setting up an OSXServer for syncing sharing, Contacts, Calendars, Notes, and Files is not difficult. But it requires a bit of planning to configure user accounts etc., so that it is easy to configure/administer the iOS and OSX devices. And of course you become the systems administrator for the OSXserver. Sharing/syncing Contacts, Calendars, Notes via OSXserver rather than iCloud will not reduce significant internet traffic/bandwidth. The main reason to switch to OSXserver is philosophical.
    Apple’s iWork apps (Pages, Numbers, Keynote) are difficult to untangle from iCloud. OSX server does support Webdav for “sharing” iWork app files between users/devices. But this is not the same a live syncing via iCloud.
    Finally, the actual untangling takes some planning to extract the contacts and calendar info from iCloud and transfer it to calDAV and cardDAV on OSXserver.
    Are you after the “practical” or “philosophical” or both?

  • Unable to download Mavericks from my list of purchases (current OSX: 10.8.5)

    Hi,
    I'm currently working on OSX 10.8.5, and am having trouble downloading Mavericks from the AppStore.
    I've previously installed Mavericks using my own Apple ID on another Mac some weeks ago.
    When I open the App Store and go to 'Purchases', I can see Mavericks in the list of available apps. However, when I try to download, I get the message 'You have updates available for other accounts' claiming that I have to 'Sign in to (AppleID) to update applications for that account.'.
    The Apple ID in question belongs to a friend of mine. I can't be sure, but he may have installed Mountain Lion on this Mac at some point. However, even when he logs in to the App Store (using Store -> Sign Out / Sign In) and tries to download Mavericks, he gets exactly the same dialog message, preventing the download from starting.
    Crytpically, the dialog message still shows the same AppleID, even though that's the currently signed-in account.
    I'm at a bit of a loss at the moment. I've tried varying combinations of signing in / out of the App Store (as well as quitting and re-launching it, in case that was the issue). I'm not really sure what to do at the moment. As it stands, I'm stuck with 10.8.5 with no possibility of installing the update.

    I would use the Mac that already has Mavericks installed and resownload the installer. Then either make a bootable Mavericks installer on a thumb drive or just transfer the installer to the other Mac.

  • I have an iMac mid-2010 running Snow Leopard. Is it possible to install Mavericks and Windows 8 on separate partitions while keeping Snow Leopard?

    I have an iMac mid-2010 running Snow Leopard 10.6.8. Is it possible to install Mavericks and Windows 8 on separate partitions while keeping Snow Leopard? If so, can you describe the steps?

    That should not be a problem as long as there is enough room on each partition for each OS.
    You would:
    Use Disk Utility to partition your HD
    Download the Mavericks installer and install it on one of the open partitions (when you run the installer from your 10.6.8 partition, it will ask you where you want to put Mavericks, and you will specify one of the open partitions).
    Use Boot Camp to install Windows on another of the open partitions. Mac Basics: Using Windows on your Mac via Boot Camp

    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 external 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.

  • Is it possible to uninstall maverick

    Since I migrated from Lion to Maverick my computer is much slower. I want to uninstall it. Is there any risk?

    First erase the disk drive, then install an earlier version of OS X using an installer for the earlier version. Or you can restore a separate backup of an earlier version. Or you can figure out why your computer is running slower. For example:
    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
         computer and after the chime press and hold down the OPTION key until the boot manager
         screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.5 update: OS X Mavericks 10.9.5 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.5 update: OS X Mavericks 10.9.5 Update (Combo).

  • Installing a fresh copy of OS X Mavericks from USB on iMac 12,1 with broken SuperDrive.

    Hi,
    I want to get a fresh copy of OS X Mavericks on my iMac 12,1 (mid-2011 - i5 2,5GHz, 8GB RAM, AMD Radeon 6750M with 512MB) with broken SuperDrive. I made a pendrive with DiskMaker X, but I can't boot it anymore on iMac. My flash drive isn' corrupt - it performs well on MacBook Pro. What can I do to install it on iMac?
    Greetings,
    Jakub Borys
    Post scriptum - Sorry for my poor English.

    Oh, man, I wish I had something useful to offer. It sounds bad. Really bad.
    Do you have a friend -- or possibly a Mac ot work -- from which you could make a new USB Mavericks installer? I only say that because I've read of a few problems here and there with boot drives made with DiskMaker X. What I'd recommend, if it's at all possible, is to download the latest Mavericks DMG file, reformat the USB drive with a fresh GUID partition and then burn the disk image onto it with the Mavericks built in createinstallmedia method. Here's a link to an article which describes how to do it: http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html. This is, in fact, the very article which got me onto the right path.
    You'd think that a bootable Mavericks installer would be a bootable Mavericks installer no matter how it was made. Sadly, that doesn't seem to be the case.

  • Clean install of Mavericks from Recovery Partition

    Can you do a clean install of Mavericks from the Recovery Partition (cmd+R on boot)?  Or do I need to put in the DVD that came with the 2010 MacBook Pro, boot to that, reformat drive, and install/upgrade from there?
    Yes, I know you can make a USB boot drive (which I don't have).  Can I boot to the recovery partition, reformat the drive, and then install Mavericks from there?  Or will there be other issues?  I do not want to restore from a Time Machine drive (which is also on the fritz), I want a clean install.  Thanks.

    To 'clean install' you need to erase the partition for OS X…
    Boot into recovery mode.
    Select Disk Utility from the options list.
    Select your boot disk in the left sidebar and then find the desired partition (these are indented below the disk icon).
    In the erase tab, erase the OS X volume and format the new partition as a 'Mac OS Extended (journaled)' volume.
    Quit Disk Utility & select the installer from the main screen.
    I'd strongly suggest you backup all the other OS's before you begin since it is possible to erase the wrong partition!
    The installer will be downloaded from Apple so you should use a wired connection if possible - wifi can be slow & unreliable, it will save time if your internet connection is faster than wifi.
