Need to uninstall yosemite asap

I need to uninstall yosemite x right now!!!  i cannot use an important program on it.

In a nutshell, you can't go backwards with Apple operating systems. Do you have a friend who's still using Mavericks or Mountain Lion?

  • Before I install MX922, do I need to uninstall drivers for MP800 first?

    My MP800 is out after many years of service due Error Code 6500. Before I install MX922, do I need to uninstall drivers for MP800? Or just install MX922 as normal? Running OS X 10.10 Yosemite on Mac mini. I want my scanned images done by MP800 to remain on my mac of course. Thanks.
    Solved!

    Hi pmt513,
    You don't have to uninstall the drivers for the PIXMA MP800 prior to installing the PIXMA MX922; however, if you would like to, you can reset the printer system on your Mac to uninstall the drivers without removing the scanned images.  To do this, please follow these steps:
    1. Choose Apple menu > System Preferences, then click Printers & Scanners.
    2. Hold down the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears. After you reset the printing system, the list of printers in Printers & Scanners preferences should be empty. If your printer is still listed on the left select your printer and then click the minus (-) button to delete it.
    3. Restart your Mac.
    You can now install the drivers for the PIXMA MX922.
    Hope this helps!

  • 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.

    Start with reinstalling Snow Leopard:
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         1. Boot the computer using the Snow Leopard 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. After you finish Setup Assistant will complete the installation after which
             you will be running a fresh install of OS X.  You can now begin the update process
             by opening Software Update and installing all recommended updates to bring your
             installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1 Access the App Store to download Mountain Lion or Yosemite. Mavericks is no longer available since the release of Yosemite. If you purchased Mountain Lion from the App Store, then you can redownload it via your Purchases page in App Store. If not, then you will need to purchase it from Apple;
    Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    My two old white MacBooks run perfect with Snow leopard, but my 2011 17" i7 Macbook Pro is a dead slug with yosimite installed.
    Tried the start with C held down, also with option held down.  All it does is beeps at me three times, then again three times..... 
    I want to remove yosimite and install Snow leopard from dvd as yosimite runs worse than a Windows OS.
    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.

  • HT1751 I need to uninstall and reinstall iTunes (it won't let me update). So, how do I copy or back up my iTunes library of over 1,500 songs? Can I use a Flash Drive to do so?

    I need to uninstall and reinstall iTunes (it won't let me update). I have IE 8 on Windows XP, and iTunes 10 something. In my Program files list I see iTunes and iTunes (2) and even iPod and iPod (2) where a tech had to back up and do this for me before. I'm just trying to fix it all. I keep getting the "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'iTunes.msi' in the box below." I can even run a search and find the folder, but it gives me the same error message. I was planning on using the Microsoft Fix-It tool  to help uninstall then Reinstall iTunes. But I need to backup my library. So, how do I copy or back up my iTunes library of over 1,500 songs? Can I copy the folder to desktop or can I use a Flash Drive to backup my music? I don't want to do anything until I know for sure how I can backup my songs, and then reinstall them into iTunes. Thanks for any help.

    Ok, thanks that helps. I don't have an external hard drive though. What about backing up through 'the cloud'? I'm just wondering since my husband syncs his iPod to the PC through iTunes and he's worried that he will lose all the songs on his iPod if the library is lost from iTunes and he tries to 'sync' it up again. I'm not exactly sure how to  'copy the entire iTunes folder' either. I kinda suck at this unless I have step by step instructions, which I haven't found yet on iTunes help or other sources.
    The only way I know how to back anything up is by going back to a restore point, etc. (as stated before, we don't have an external hard drive.)
    Thanks for the info.

  • I need to uninstall my old version on itunes and install a new version, i cant uninstall from Programs and Features, a message keeps coming up saying 'The feature you are trying to use is on a network resource that is unavailable.' Can anyone help please

    I have tried to just install the new version of itunes from the apple website, it looks like it downloads but after 5 minutes at the end of the install it says 'old version of itunes cannot be uninstalled, please contact support.'?

    Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
    Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
    If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
    Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
    Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly now?
    (If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

  • I need to uninstall Adobe Flash Player Installer/Uninstaller 14.0 r0

    I need to uninstall Adobe® Flash® Player Installer/Uninstaller 14.0 r0 but have looked everywhere for how to do this & can not find out how to do this can someone please help? I am using A Sony Vaio, Windows Vista Home Premium 32 bit, I use Chrome Version 36.0.1985.143 m.
    I want to get it off of my system because ever since I installed it I have had problems with Chrome loading it does not want to load then if I restart my comptuter & I click on chrome  5 windows open up at one time a white box appears saying "Your profile can not be used because it is from a newer browser version of google chrome. Some features may be available. Please specify a different profile directory  or use a different version of chrome" then if you click ok it shuts all the windows down. I have figured a way to get one window to stay open so I can use chrome, now I do have other browser I can use but I do not like them  at all & do not have a flash player since mine is built in with Chrome. So on to the other problem that began as soon as I downloaded this & I understand it may not be this but I still want to get it off of my computer. I also have been having trouble with my flash player error messages: saying it has stopped working constantly, it says upgrade flash text, a plug in shock wave flash isn't responding then in (stop plug in) it wants you to hit.  I have run 3 different Mallware programs through my computer just in case that was one question that was going to be ask. No other programs jave been downloaded wither.
    I am not very good with computers so I have to come to places like this for help & I really have to have help explaining what to do because  do not know much about computers other then getting on them & surfing the web & some basic things. When chromes message said specify a different profile directory that went right over m head. So that should give you an idea where I am coming from. I want to thank you in advance & hope I have made sense in what I have written I tried to give all the information that I could.

    Your screenshot of task manager clarifies things.
    When I replied, I had been looking at the screenshot of the desktop from the original poster, which shows the uninstaller executable and it's properties.  That executable doesn't install anything -- it can just be dragged to the trash; however, that didn't completely align with the behaviors either of you were describing, and we've been trying to figure out what you were talking about.  It wasn't making a lot of sense to me, and it's not a question that I've seen come up before, at least not articulated this way.
    FlashUtil32_XX_XX_XX_XX.exe is the sandbox broker for Internet Explorer.  You can read more about the sandbox work here: Flash Player Security with Windows 8 and Internet Explorer 10
    The description listed in Task Manager is a bug, and the source of the confusion.  We've been doing a lot of work modernizing our build systems, and this is fallout from that work. This is something I'd like to see cleaned up, but it's pretty low on the list of priorities.
    The broker service is invoked when Internet Explorer is running in Protected Mode.  On my Windows 7 machine running IE 10, running Flash content in Internet Explorer with Protected Mode enabled causes the broker service to be invoked (this is probably true for previous versions as well, but I didn't test them).  If I disable Protected Mode and restart Internet Explorer, the broker is not invoked, which is expected.
    To disable Protected Mode, launch Internet Explorer and choose security.  Uncheck Enable Protected Mode.  Internet Explorer will restart, and you should be able to verify that the broker is no longer invoked when loading content with Flash Player.
    I've included a screenshot showing the expected processes in both scenarios below.  As the Flash Player ActiveX control is loaded into an Internet Explorer process, you'll see the child explorer.exe process listed, which hosts the Flash ActiveX control in the process list.
    Sandboxing the Flash Player plug-in is an important security mitigation intended to increase the cost of successfully developing and deploying malware.  While it's not a panacea, it significantly raises the bar for attackers.  As I'm sure you've read in the news and trade literature, the threat landscape has evolved significantly over the last few years, and modern security threats and their mitigations are a necessary reality.  New mitigations typically come with some additional processing overhead.  The overhead varies based on the architectural choices made by the particular browser vendors, but the overhead in IE is pretty reasonable.
    We haven't published a blog post specific to IE, but if you're interested in the implementation details, the sandbox architecture is similar to what we did with Protected Mode for Firefox on Windows.  The Flash Player process that handles untrusted content runs at Low Integrity, which restricts access to critical system resources in the event that you encounter malware designed to take control of the Flash Player process.  Access to system resources is negotiated through a Medium Integrity broker process.  Without Protected Mode, the Flash Player process handling untrusted content runs at Medium Integrity, making it easier for malware to escalate privileges from a hijacked process.  Depending on the functionality in play, a lot of message-passing can take place between IE, the broker and Flash Player.  We've effectively doubled the number of messages that get passed, plus put a bunch of validation checks in, and all of that consumes CPU.  It also makes your web browsing activity more secure.
    Some desktop applications (Yahoo Messenger, for example) also use the ActiveX version of Flash Player installed on your machine.  This could explain why you see Flash Player and the broker invoked unexpectedly.  We're also aware of an issue on Vista where the broker doesn't always exit as expected.  In that instance (and on WinXP), I'd highly recommend that people use Google Chrome for web browsing, as Google has extended some security mitigations that would only be available to Internet Explorer users running in newer versions of Windows, and it doesn't suffer from this specific issue with the broker.

  • Do I need to uninstall Crystal Reports Server 2008?

    Hello,
    We recently installed Crystal Reports Server 2008 and began migrating reports off the CR Enterprise 9 platform and things were going pretty well.
    One of our other locations began moving over their reports that are ran against an Oracle database and cannot get passed a connectivity issue. We found the following:
    Oracle connectivity issues
    If you are installing Crystal Reports Server 2008 V1 on a 64-bit Windows
    platform, Oracle database connectivity issues may occur. If Crystal Reports
    Server 2008 V1 is installed to a location that contains brackets in the folder
    path, for example, C:\Program Files (x86)\, it will be unable to connect
    to an Oracle database. Certain Oracle database clients such as version
    10.2.0.2 or 10.1.0.2, may not function properly with any application that
    has brackets in its folder path. When installing Crystal Reports Server 2008
    V1, select an installation path that does not contain brackets, such as
    C:\Program Files x86\ or contact Oracle support for an updated database
    client.
    We of course have everything installed in the default (x86) folder. My question is, is there a way to move the installation, or do I need to uninstall/re-install? If I need to re-install, is there a way to back-up and reload all of my existing jobs?

    Hello,
    CR must have the Oracle client installed. Unless you use a Wired Driver, which has the client engine built in, CR requires a client to be installed. It never has worked without the client installed.
    Also, I've found that if you have more than one Oracle client installed it causes problems. Make sure the first one in the PATH statement points to the latest version of the client.
    And yes you are correct, ODBC is a layer on top of the native client so it will be slower obviously because it has to go through one more layer of dll's to get to the server.
    Thanks again
