Can I un-install Yosemite from my iMac and re-install Mountain Lion?

Can I un-install Yosemite from my iMac and re-install Mountain Lion?

Sorry to barge in like this but is it because you found it to have it's own way of doing stuff without your control? As i was thinking of doing the same thing because i found Mountain Lion much more user friendly.I know you came for an answer just was searching and came accross your question.
Hope you find the answer. good luck.

  • Can I unstall Office 2011 from a Macbook and re-install the same software on a different Mac/Mackbook?

    Hi all,
    I’ve looked around Google and here and I can’t find a definitive answer to my question so hopefully you guys can give me some advice
    I bought the Office package in 2011 when it was new and installed it on my Macbook. I now plan to buy an iMac for the purpose of studying so I'd like to remove it from my Macbook and transfer it to the new Mac. My Macbook is running on the current highest software (the name escapes me at present, I'm not on it to check) and I assume the Mac will be too. If I were to uninstall everything, would I be able to use the same disc (i.e. same unique code) on the other computer? I believe I only have the 1 disc 1 Mac version so can't have two running with the same software.
    Ideally I'd not like to buy another Office package so any advice would be much appreciated. I realise I may not have much choice though...!
    Many thanks for your assistance.
    Kind Regards,

    New Mac's come with OS X 10.8 so you would have to check compatibility of your software with the new OS X versions.
    http://roaringapps.com/apps:table
    Next you will have to check if the software will install or not on 10.8 from the disk, since the disk is static it can't change for newer OS X versions, however the software itself might run fine if a more recently updated version is downloaded  and installed, then the license key entered.
    Far as licensing concerns, you will have to check with the developer how to go about deauthorizing, uninstalling and getting a new license key for the new machine or if you can continue to use the existing one.
    Most licenses are for one machine, however some can be multiple machine packs.
    If you don't exactly need Office specifically to work with other Office users, you can also install the free LibreOffice and it can open your Office files.
    The thing with Office is it's widely used in businesses, so if you learned it already then it doesn't make much sense to continue using it and paying money for only personal use.
    https://www.libreoffice.org/
    LibreOffice is truly cross platform, Linux, OS X and Windows. The files are easily exchange and many Mac users are thrilled using it apparently as the developers have commented a great deal of Mac users are installing it.
    If you have trouble installing, it's likely Gatekeeper security that's on the new 10.8 machines, simply hold control key and click on the installer/program and select "Open" and it will remmeber it's a trusted program from then on.

  • What external Hard drive can I get to use w/ my iMac and Macbook pro w/ Lion software? I have never used one. I need to back up my photos, iTunes, documenta, etc., Im a nursing student and very worried about losing my stuff. Any suggestions?

    I have had my macbook pro and desktop since 2008 now.  I have never had time to just sit down and learn about time machine and external hard drives.  I am in nursing school and barely have time to breathe, so when I try to read the threads, all the tech terms run together.  I have been referred to LaCIe, but I read some things saying problems with Lion (which I am highly disapointed in so far-but like I said, I have not had a lot of time to sit down and try to figure out out the kinks), Is there a good external harddrive anyone reccommends that will be easy/simple (not because I am lazy- I literally have no time w/ all my school work to figure out something complicated) , and go with my desk top and lap top?
    My laptop started messing up in class the other day, and it has a lot of memory left, so I don't understand.  It kept freezing up like a PC.  Ever since I downloaded Lion, it seems my computers have gotten slower. ;(    I have MacKeeper downloaded on both of them. I cleaned stuff off, it seems to be working better right now. But I am still soooo scared that something will happen and I will lose all of my info.
    I would be grateful of any advice/suggestions that anyone can give me. 
    Thanks

  • HT4352 I can't get the mirror from my mac book even with mountain lion and my tv is 1080p ?

    im having trouble using the mirror from my mac book with montain lion 10.2 and a tv with 1080p res. and apple tv

    Hi Lancebe
    Is your macbook mid2011 or newer if it is air or early 2011 or newer if it is pro.  If not it does not support mirror and you would need a third party app such as www.airparrot.com . If it is a compatable mac then post again and give a little detail of your set up and what the problems are.

  • I have a late 2012 iMac and a late 2009 mac mini.  I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.

    I have a late 2012 iMac and a late 2009 mac mini.  I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.
    According to Cruicial my mac mini could use:
    Module Size: 8GB Kit (4GBx2)
    Package: 204-pin SODIMM
    Feature: DDR3 PC3-8500
    Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V • 512Meg x 64
    Also According to Cruical my iMac uses:
    Module Size: 8GB Kit (4GBx2)
    Package: 204-pin SODIMM
    Feature: DDR3 PC3-12800
    Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V
    I want to increase the ram in both computers. 
    So,  can I put the iMac ram in my mac mini and then I'd only have to buy ram for my iMac?  Naturally the ulitmate test will be when I actually install it,  but having an expectation of success or failure will allow me to plan on what to spend money on.
    Thanks,
    Bear

    Thanks for the responses.  I probably wont even try as my priority is Ram for the mac mini.  2 is not enough.  8 for my imac is okay for now. 
    Somewhere I thought I'd heard that faster Ram would simply clock at the lower speed.  It seems that I am incorrect.
    Thanks,

  • Can I switch out a hard drive for an SSD without having to clone the existing hard drive, and then install Yosemite from an USB Boot Drive onto the new SSD?

    Can I simply replace a hard drive with a new SSD and just install Yosemite from a USB boot drive onto the SSD? I recently bought a used MBP and it has absolutely no files on it except for the OS, and so I'm assuming I don't need to clone the current hard drive as I can just reinstall the OS onto the new SSD.

    Thanks.
    Just a quick follow up question, is formatting the SSD with HFS+ done in Disk Utility?...
    It's possible that the SSD will be set up for use on a PC, which means it will have a Master Boot Record partition table rather than a GUID Partition Table, which is what Yosemite needs. In Disk Utility, select the SSD and click the Partition button. Create a new Partition Layout and click the Options... button at the bottom. You'll likely see MBR is selected. Choose GUID instead and Mac OS Extended (Journaled) for the Format.

  • I installed Yosemite from Mountain Lion and my photos have disappeared.  How do I recover?

    I installed Yosemite on my iMac (late 2009, storage 8GB, processor 2.8 GHz Intel core i7).  previously using Mountain Lion (10.8.2)  I had stored many photos on iPhoto that weren't on the Cloud.  Now I cannot access these photos.  How do I recover? 

    Now I cannot access these photos.
    You need to update to iPhoto 9.6.1. Only that is fully compatible with MacOS X 10.10.3.
    You can no longer buy iPhoto from the App Store anywhere, and also not update it from the "Updates" tab of the App Store. You can however reinstall it, if it is showing among your Purchases at the App Store and associated with your AppleID.
    Sign into the App Store and look at the Purchases tab.  If you do not see iPhoto there, try to unhide your Purchases as described on this page:   Hide and unhide purchases in the Mac App Store - Apple Support
    If iPhoto shows on your Purchases tab, reinstall as described in this User Tip:
    Get iPhoto 9.6.1 if you didn't update before OS... | Apple Support Communities
    The main idea is to move the incompatible iPhoto app to the Trash, so Spotlight does not see it as installed, reload the App Store by pressing ⌘R, and then to try to download again from the App Store - from your Purchases tab, not from the main page, since you can neither buy iPhoto nor update it, but you can reinstall, if your AppleID is associated with it.
    So move iPhoto to the Trash (don't empty the Trash), relaunch the App Store. The button to the right if iPhoto should change to Install on the "Purchases" tab.
    Alternately, you could migrate your iPhoto library to the new Photos.app.
    When you launch Photos, it will try to migrate your iphoto Library, if it can find the library.  Where is your iPhoto Library stored? If it is in your Pictures folder, simply drag the iPhoto Library to the Phots icon in your Dock to migrate it to Photos.
    Photos will make a migrated copy, so you still can use your iPhoto Library with iPhoto.

  • I have already downloaded OS Yosemite (it says so on my Apple About this mac overview) but now I keep getting a message from "install Yosemite" that keeps asking me to install Yosemite again and won't go away.

    What do I do? I have already downloaded OS Yosemite (it says so on my Apple>About this mac>overview) but now I keep getting a message from "install Yosemite" that keeps asking me to install Yosemite again and won't go away.

    I have the same issue. My computer has also slowed down. I hope this isn't a malware. I haven't input my password into it, and dont know what I did to turn this on.

  • I just bought a new IMac. I have photoshop elements installed on my old IMac and would like to move it to the new one. How can i do this?

    I just bought a new IMac. I have photoshop elements installed on my old IMac and would like to move it to the new one. How can i do this?

    Unfortunately, adobe doesn't have photoshop elements 6 available for download, as far as i know, so your best bet is to either get an usb dvd drive or use an computer with a dvd drive and copy the contents of the pse 6 dvd to somethiing like
    a flash drive and then copy the contents from that drive to your new computer.
    Do you still have your older mac and it has a dvd drive?
    You can share files between the two using airdrop or an ethernet cable.

  • How to get iPhoto and iTunes to a clean installed Yosemite from Time Machine

    I wiped the Hard Drive and clean installed to OS X Yosemite. For Some reason, some of my Time Machine back ups disappeared or got deleted and it wasn't even full. I had back ups from 2011 and now it only starts from 2013 of June.
    Next....when I try to restore my other apps(like iPhoto and my iTunes) I doesn't give that warp space effect in the background. It gives me the window layer effect but I just see the same mountain background on the desktop as the default Yosemite(unless thats how its suppose to look like that?) I can't restore using Time Machine because the little lines at the right are red (see screen shot) and it won't let me restore, and if i go back by using the arrows, if freezes. So,
    I don't know how to install the old iTunes and iPhoto on my existing clean installed Yosemite from my Time Machine.
    Can someone help me?

    @ LarryHN Thank you ver much for you help I understand now that you just can't copy over the old library(got it)
    I had the latest version of iPhoto before I cleaned installed.
    The link you gave me was most informative and I want to thank you. But still problems arrive.
    This came up and I don't know which one to pick

    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.
