Can I uninstall Yosemite and reload my older operating system

can I uninstall Yosemite and reload my older operating system

I tried this method and erased my MC HD and restored my system, but the bad thing is once you install YOSEMITE it overrides your Recovery with yosemite and you lose Maverick. I called Apple support regarding this same issue. I have to take my Mac to apple to have it replaced with a new one that has maverick installed on it.
Yosemite is causing display glitches, wifi slow downs, dock disappears from one screen to the other or completely and cannot get it back.

  • How can I uninstall yosemite and reinstall Loin with out losing all my in formation and programs

    How can I uninstall Yosemite and reinstall Loin with out losing all my in formation and programsThis had been the worst os system apple has come out, too many errors
    too many to list.
    a few
    Losing all mail. and watching them disappear in front of my eyes and could nothing about it
    also when accessing cloud the screen just rolls in when accessing mail, like loading and loading and loading for 1 to 2 minuets.
    I did not up grade my Mac Book Pro, and is working fine,
    Just my iMac, its act kile avid card and it only happens access iCloud mail.
    so I want to and need to go back to Loin

    You can't unless you have a current backup of your old Lion system because the first thing you must do is erase the drive. It 's possible to use Target Disk Mode between your iMac and the MBP in order to clone the MBP to the iMac. However, that will still erase everything on the iMac's drive.
    Or you could see about getting Yosemite to work correctly. If you have IMAP mail, then your mail should be intact.
    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.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
    Download and install the 10.10.1 update.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    5. Reinstall Yosemite from Scratch:
    Download and install the 10.10.1 update.
    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.

  • Can I uninstall Yosemite and go back to my old OS?

    Can I uninstall Yosemite and go back to my old OS?

    It's not a simple uninstall. You'll need to erase the hard drive, install the old OS version, and then restore your data from a backup. It's a time consuming process and it's probably easier to try and troubleshoot whatever issues you're having with Yosemite.

  • Is it possible to uninstall yosemite and reload maverick

    is it possible to uninstall the operating system yosemite, and reinstall the maverick operating system

    If you were wise you would consider other options just besides getting rid of Leopard and throwing it away. First, you could wait until Apple releases OS 10.5.1, then install and update to it. This might help take care of some problems. You could dual boot OS 10.4.10 and 10.5 as long as you have the OS 10.4 full install Disk and the OS 10.5 full install disk. I personally will wait until at least Christmas time before I install Leopard. New OS's are always full of bugs. On the Microsoft side, I've read where Windows Vista is still having major problems and is taking a long time to become widely used. These problems take time to fix. When Windows XP came out nobody would upgrade to it because of all it's bugs, now Windows XP is considered the standard on PCs. Mac OS 10.4 was also full of bugs at first, but now we talk about how rock solid it is. Simply give Apple time to fix these problems.

    I have quicktime pro and it does NOT have the screen record mode that Quicktime is suppose to have.  Can I uninstall it and go back to an older version that would have screen recording?  If so, how?  Step by step needed.  Thank you for your time.

    Did you remove Quicktime X?
    On a normal install Quicktime 7 is installed in the Utilities folder and Quicktime Pro in the main Applications folder.
    You will need to reinstall OS X to get Quicktime X back if you have deleted it.
    I notice yor profile says 10.5.8. Quicktime X is only available on 10.6 and above.

    Can it be done, what do I need to do please?
    Examples of faults,  even with a 1tb solid state drive and 16 gig of ram, it is incredibly slow.  Took four hours to install Logic 8 last night, I still have to reinstall logic 9 upgrade.   On the White MacBooks I got both 8 and 9 installed in under an hour and a half all up.
    Beeping on startup means failed RAM.
    Slowness is usually caused by incompatible third-party system modifications.

  • Acrobat Pro 8, 9 and X installed. Can I uninstall 8 and 9?

    I migrated my old MacBook Pro to my new MacBook Pro in January (OS X 10.7.4).  I now have 3 versions of Acrobat Pro on my Mac, Pro 8, Pro 9 and Pro X.  Can I uninstall 8 and 9 without having to re-install X?

    Hi Robin,
    As Bill said, you should be able to uninstall Acro 8 & Acro 9 without having to reinstall AcroX.  Each of the versions is fairly well isolated from each other on the Mac.
    Let us know if you have any trouble!

  • How can I uninstall Bootcamp and Recover the partition for the Mac HD

    How can I uninstall Bootcamp and recover the partition for the IMac HD?

    Boot into OSX.  Go back into the Bootcamp utility in the Utilities folder and re-run it.  It will give you the option to remove the Windows partition and make the OSX partition fill the whole drive again.  OSX will NOT be lost in the process.  No re-installing necessary.  Only takes a few minutes or less to complete.

  • 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.

    Only with a whole lot of effort and instability.  As the new Minis have
    hardware (HD4000, USB 3.0, etc.) that is totally unsupported in old OSes.
    The only option would be to see if it would work by installing in a virtual machine
    running 10.6.8.  I'm sure there will be some performance hit but whether it would
    be enough to be unusable is the question.

    Hi,
    Not sure if any of you above have managed to solve your problem or not but after coming across this same problem myself today as I am currently 'sofa bound' I decided to make it my mission to find a way around it.
    Initially I did think, having ready what seemed like a million questions and people with the same problem, that the only way was to buy OS X 10.5 ... HOWEVER, no. In among all these threads I found a jewel - Download I Tunes 9.2.1 which gets rid of the download itunes 10 advert and allows you to then buy from itunes again :-)  I am now one very happy lady.
    I apologise to all those that dont have older versions of OS X that maybe wont support even this upgrade but certainly for those like me with just 4yr old lap tops at least it means it not longer means buying a new one.
    Hope this helps son very frustrated people like myself - so much for apple support!
