How do I revert back to OS Mountain Lion from Yosemite
My MAC Runs like a Dog and takes ages to boot up after upgrading to Yosemite. Is there a procedure to follow that allows me to go back to an earlier operating system ?
Hey Gary!
Officially, downgrading your system to any previous version isn't supported by Apple.
There are other third party sites that offer suggestions to downgrade, which some for example are:
- http://osxdaily.com/2014/10/22/downgrade-os-x-yosemite-to-mavericks/
- http://www.gottabemobile.com/2014/10/20/ipad-air-2-release-date-info/
- https://bgr.com/2014/10/23/yosemite-to-mavericks-downgrade/
With downgrading, make sure to backup all of your information! If you do not like those options, you can always Google search "Downgrading from Yosemite to Mavericks" or something along those lines for more options.

Revert back to osx mountain lion from mavericks?
Since updating to osx mavericks I have encountered numerous issues with my multi display set up to the extent that I have decided to go back to mountain lion
My question is how do I go about doing this as I have tried to go through the recovery but this only gives me the option to install mavericks
I have daily back ups so data loss is not a threat and I understand that erasing the drive is the most likely option
Any help will be appreciated I need this fixed ASAP as I need the set up for audio & video editing work!!!Mistakericks.

How can I downgrade back to OSX Mountain Lion From OSX Mavericks without any Time Machines Backups
How do I downgrade from OSX Mavericks to OSX Mountain Lion. I do NOT have a Time Machine Backup and I dont want to lose all my files. Is there a way to downgrade WITHOUT a Time Machine Backup and still have all my files????
Since you need to erase your hard drive in order to downgrade, you would lose all your files. You cannot do what you want without erasing, so make a backup first.

Reverting back to OSX Mountain Lion
Can someone please tell me if I can revert back to OSX Mountain Lion from yosemite w/out affecting my backed up file's?
some of my files predate mavericks, other's don't.
Thank You!This is my Etre check since wiping my hard drive...can't seem to get rid of Macpaw for some reason. There is also still a "Hosts" issue. I am calling Motorolla today to discuss my modem & built in router as there also seems to be a "Wi-fi" network issue on this computer since the yosemite upgrade. Will this ever end? Is there a way for me to manually remove the leftover traces of Macpaw & also address the host's issue? Also wondering how to reset keychain so the constant password prompts for every single program including Chrome & Safari end. Computer is also still unstable and shuts down randomly since the reinstall. I am beyond frustrated at this point. Can you tell?

HT201364 how do I uninstall OS X Mavericks and revert back to OS mountain lion?
how do I uninstall OS X Mavericks and revert back to OS mountain lion?
You can't uninstall an OS X version. You would have to erase the drive and reinstall a prior OS version. That's why you should never upgrade without having a backup.
However, just about any router in the world should work with Mavericks, without the need of any DVD supplied software. -
New Mac Mini - How do i reinstall my copy of Mountain LIon from App Store?
Hi All:
I just bought a new Mac Mini running Mountain Lion. I want to clone an older system drive that had been running Snow Leopard onto my new Mini and then upgrade to Mountain Lion (I tried Migration Assistant first, but it didn't work correctly and I don't want to mess with it again).
My question: once I have a working Snow Leopard install on my Mini, is it possible to upgrade back to the Mountain Lion OS it came with without paying for a new copy? How do I do that?
Thanks!It isn't just the hard drive - there is firmware built in that will prevent you from booting wih Snow Leopard. If you do a search here, you'll find many threads trying to install an earlier OS than what the machine came with all with the same answer (unless the Mac was built right around the time of a new OS being introduced, then it is possible to be booted from both OS's). In this case, you'd be trying to go backwards by 2 versions. Also see here:
http://support.apple.com/kb/HT2186?viewlocale=en_US
And yes, if you use internet recovery and first erase the drive (available in Disk Utility within the recovery partition) and then reinstall the OS, it'll reinstall the OS on a blank drive and you can start over. If the machine is new, then Command + R during restart should automatically boot into internet recovery (connecting you to Apple's servers by showing a spinning globe while connecting); if the machine is a bit older, then Command + Option + R will boot into internet recovery. -
I just bought a new car. Hyundia Hybrid. My bluetooth is not Reconizing my command to call a contact. I've been back to the dealer and no luck. When speaking to Bluetooth support directly he doesn't see Version 6.1. and suggested going back to Version 5.1 which is documented to be compatable with my Iphone 4s.
I doubt it because voice recognition takes the command " Call Wife" Can I revert back to 5.1 without clearing my phone back to origional settings?I'm sorry, but Apple does not provide a downgrade path for iOS. Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any iDevice.

How can I switch back to OS X Lion from Mountain lion?
I have a Native Instruments Traktor Kontrol S4, and it stopped working after upgrading to Mountain Lion. Instead of music coming out of the speakers, it is a repetetive crackling noice and the track stops and goes. I just want to downgrade so I don't have to worry about the problem until they come out with an update. I have a performance coming up and I need everything to work! Thanks.
Actually you are right, i ll stay on Mountain Lion. I have a problem with AppStore here is the link of my problem i post it a few minute ago.

I hope that someone can help me to fix it -
Okay so about 2 weeks ago, maybe less, my mom purchased a used IMac and then upgraded to Mountain Lion. Ever since she powered on the computer I haven't had the same capabilities on my PC laptop as I used to. Youtube takes forever for the videos to load and sometimes doesn't load at all. On skype when my friends send files it's estimated to take hours what should only take moments to download.
Around the same time as when we got the IMac, I had also installed a laucher for a website that was required by my school in order to do my work. At first I thought that was what was causing the slow internet and I swiftly uninstalled it, but the problem still continued. Please I know there could be other reasons for the slow internet but I really want to explore this possibility. Please, I really want my internet back.
Imploringly,
JessicaTry some trouble shooting
Step 1
Does iMac have slow internet as well?
Yes - Problem may be Modem/router. Proceed step 4
No - Proceed step 2
Step 2
Shut down iMac.
Does PC wifi issue still exist?
Yes - It is not the iMac. Proceed step 3
No - Need smarter people to help
Step 3
Use wired connection on PC laptop. Leave iMac Shut down
Does PC laptop still have slow internet?
Yes - Not a wifi problem. Maybe the PC software.
No - Wi Fi issue. Maybe PC wifi or modem/router. Proceed step 4
Step 4
Turn power off on modem/router, count to ten, then turn on. Wait for connection to re establish.
Does issue still exist?
Yes - May be Modem/router wifi channel conflick with your neighbours wifi. Proceed step 5
No - Just needed a reboot. Surf safe.
Step 5
Consult the modem/router manual for changing wireless channel. -
Going back too Mountain Lion from Yosemite on new Mac Book Pro
Okay so I just got my first Macbook Pro I am Very happy with it I don't have any real problems with Yosemite HOWEVER I bought my mac as I am a music student and I work with macs all the time running Pro Tools so it made sense to get a mac for compatibility reasons. now, I am not able to install Pro Tools Express the program I use at home online there are claims that it is the installer that is broken and won't work unless you are running 10.9 or lower but the program runs fine. I have bought Mountain Lion and I am awaiting it to be emailed to me, and I am away to create a partition on my 8gb usb stick to put the installer on, I understand that apparently I can't downgrade as I have a new Mac but I can run them together? Well one at a time obviously, I just would like some help as I am a little confused having only ever used Windows before.
Thank you for any help! I'm just getting pretty frustrated with this whole ordeal.Virtual Machine for 10.7/10.8

New songs are not showing up on the ipod display but when I view the device on my computer, they are in the playlist but there is a dashed circle beside the missing songs. It previously synced perfectly before the IOS update. How can i revert back to the previous installed version?
Downgrading the iOS is not supported by Apple.

how do I revert back to previous (before 11) itunes.
Someone nicked my Album Cover flow, without asking. I have snow leopard. I was happy. Just before Christmas as if I havent got enough to do Thank You. I've given Apple loads of money this year--presents and all, the least they could do is tell me, they're going to take stuff off of My computer that I enjoy,/ find very useful/ and worked hard to update all my album covers and have a gallery of my own artwork for my mixes--it was beautiful. When I went to add some more, the facility had been taken away from me. Was so dissapointed. They send me emails all the time to buy the latest must have products. I even did a questionair to help them. They really care for their customers--right. So why couldnt they warn me about this update, its only polite.
If I bought a warm coat some years ago, then the manufatures came round without my knowledge and cut off the left arm, and later told me, their reserch says that people dont use the left arm so much so they have to get rid of it. 1. I think that would be illegal. 2. its impolite not to ask if they could do it. 3. why not give me an options to keep it, seeing as i bought it. 4. its ludicrous.
I trusted Apple-but then -they took my YouTube off my ipad. I cant update to newer software as I will lose some expensive programms (Im not made of money). I also have 2 oldish defunct but fully working laser printers (if they were compatible with new software).
Im not a techky-I just use the stuff, I do art and music and Cover Flow was equipement I used.
I want to get rid of itunes 11, anyhelp out thereclick the blue download button...

An upgrade was sent to my Samsung Galaxy S5 phone on 3/27/15 and it ruined my phone. I no longer have the ability to Wi-Fi. When I swipe the phone on there is a clicking sound and the scree goes directly to my keypad. I want the phone to go to my home screen like it did before. My apps that had a black background now have a white background which is impossible to see outdoors. I want the black background back for settings, clock, and calculator. Samsung tech support says this stuff is default with the new upgrade. How do I revert back to the version I had before without having to put the phone back to factory settings and lose all my pictures, memos and other files I have accumulated over the last year that I have had the phone. I am desparate. Please help me. Send an e-mail to (removed)
