Revert from Yosemite to Maverick

I downloaded Yosemite a few days ago and made the bone headed mistake of not backing up my files before upgrading to yosemite, my macbook pro won't start up normal without freezing a getting the spinning wheel. The only way I can get into my Macbook is to do safe mode start up. I've tried repairing the disk but no help. I want to revert from yosemite back to maverick, I don't have another Mac to get Maverick from to put on a thumb drive but I read somewhere that I could go to the app store and go to "purchases" and re download Maverick through safe mode, would that work? I also don't want it to delete my files if I do that.

You must first erase the hard drive and install an earlier version of OS X that will work in order to re-download Mavericks. So you need to install the original version of OS X that came with your computer. However, if that version preceded Snow Leopard, then you can reinstall Snow Leopard from the retail DVD and update it to 10.6.8. If your computer came with Lion or later pre-installed then do this:
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:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed 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.
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.
This should restore the version of OS X originally pre-installed on the computer.

Roll back from yosemite to mavericks without time machine

I am currently a user of Retina Macbook Pro late 2013, 13", i5 with 2.4 GHz, 8gb, 1600MHz DDR3.
I faced a huge problem after updating my mac from Mavericks 10.9.5 to Yosemite 10.10, this has caused my mac to running slow, but before updating it was so smooth and worked perfectly.
- Yosemite causes my mac to be so laggy when scrolling up and down. Sometimes, it crashes all of a sudden when you are just watching a video using Safari.
- Scrolling through PDF files is so laggy
- Minimizing Apps is not as smooth as before.
My Question :
- How to roll back to mavericks/ downgrade from yosemite to mavericks? provided that i didn't not have a time machine backup. And so far i could not find any installer for mavericks in app store.

No. You need to first erase the drive then install Mavericks. Try backing up your files (Home folder) somewhere. Boot from your Mavericks drive. From it use Disk Utility to erase your Yosemite drive. Clone the Mavericks drive to the drive you just erased. Now restore your data from the backup you made.
Of course if your Mavericks drive also has a current copy of your Home folder from the Yosemite computer, then all you need to do is boot from it, erase the Yosemite drive, clone the Mavericks drive and you're done.

If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.

After restoring from TC from Yosemite to Mavericks, I lost my Parallels virtual machine. Any way to restore?

My situation was that my older iMac met the bare minimum requirements to use Yosemite so I went for it. It was super slow so I decided to go backwards from Yosemite back to Mavericks.
I booted in the internet recovery mode and restored from my TC backup. Took a long time (like 9+ hours) for this process to run its course. When it completed, all appears well except that it seems I've lost the virtual machines I had installed using the software Parallels. This makes sense I guess as my hard drive was wiped to make room for it. It didn't hit me that this would happen as when I upgraded to Yosemite it was working just on that part of the hard drive. Just ran with going backwards (my fault) for not thinking that the entire hard drive would be wiped.
So, long intro to asking, is there any way to restore that virtual machine from a TC backup? Not sure if those files are saved somewhere on the Mac or in TC to somehow restore?
Thanks.

Boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Erase and format the hard drive (Mac OS Extended (Journaled). Then reinstall the OS. Use Setup Assistant to transfer from Time Machine.

I can't access my pages documents when i downgraded from yosemite to maverick

So i do a backup before i get yosemite and then i get yosemite. i also get the update for pages. a week later i decide i do not want yosemite so i downgrade by restoring the time machine backup i did before i got yosemite but in the week i had yosemite i made some page documents and i knew they wouldn't be there when i went back to maverick so i copied them onto a usb. i now have maverick but it won't let me open the files on that usb because they were made using the new version of pages. is there a way so i can access them again? please help. also i am using a macbook air if that helps.

The only way you'll be able to access them is to use Time Machine to revert back to a version that was saved before you updated Pages.
If you still had the newest version of Pages you could export the documents to Pages '09 format, and then update them to the version of Pages you have.

Can i downgrade from Yosemite to Mavericks by using Mavericks Time Machine Backup?

Hey guys! Well I am in the position of needing to buy a new Mac, but I need it to be on Mavericks due to programs that I run and stability issues. I would love to get one of the new mac minis, but am aware that they ship with OS X Yosemite. Is it true that I can downgrade to Mavericks by restoring the new mac mini from a Time Machine backup that was done on Mavericks? I have heard that this will work but wanted to make sure before I move forward.
Just to be clear, I would take a Mac Mini that has Yosemite on it and restore it from a Time Machine backup that was done from my old Mac (Mac Book Pro 17") that was on the latest version of Mavericks.
Thanks so much guys!

There should be a hidden Recovery HD on your Time Machine backup drive. Boot using OPTION booting:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the icon labeled Recovery HD 10.10.
5. Click on the arrow button below the icon.
Then do this:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select the volume you wish to erase from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit Disk Utility and return to the Main Menu.
Select Restore from a Time Machine backup and click on the Continue button.

IPhoto compatibility, downgrading from Yosemite to Mavericks

MacBook Pro (13-inch, Mid 2012)
Hi everyone, this is my first post on Apple Support Communities, so please be kind if any mistake.
I upgraded to Yosemite as soon as the update became available, and I'm running the latest version. 10.10.1, Now, after a month or so of having it, I have had more problems than advantages from this update, and I am going to downgrade back to Mavericks.
I'm truly worried about my iPhoto library, do you know if after being upgraded to Yosemite it becomes incompatible with previous versions of OS X?
Thanks in advance for your replies.
BR,
-Nayith

This is why I always have a previous backup of both my last OS X and I duplicate my iPhoto library several times so I still have an iPhoto library that is still compatible with a previous versions of my OS X and iPboto.
Search for, download, install and try/use iPhoto Library Manager.
This app has the capability to rebuild iPhoto Library folders.
Good Luck!

Failure to step back from Yosemite to Mavericks

I can see a lot of issues here with Yosemite, but not my two:
1) Canon Isensys MF8380Cdw driver fails to print "Filter failure", even after re-installing the Mac driver. Canon do not support Yosemite.
2) Avid Pro-Tools has major problems (Blank dropdown menus but probably more). I wish I had see the advice on the Avid site not to install Yosemiite.
cmd R only offers Yosemite restore.
Anyway I tried Alt Cmd R boot to install Mavericks from the web.
This failed three times. First time it said validation of the download failed. The second and third failure (after two hours download each) did not say what the failure was, but presented the log.
A vast amount of data there, but no way to save "You do not have permission" . Mightily odd as it presented the root folder. Navigation presented few options - basically just the SSD, which said I didn't have permission again! Ah - I should have tried plugging in a USB drive.
I am now re-installing Yosemite - from scratch via cmd r - so the FIVE downloads are probably approaching 15GB!
Any suggestions, before I try again, and use up even more of my broaddband allowance (8-)#

Best you do it this way:
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:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed 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.
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.
This should restore the version of OS X originally pre-installed on the computer. Now, you should try installing Yosemite.

Reverted back to Maverick from Yosemite - extremely slow

I just spent an entire weekend reverting from Yosemite back to the previous operating system. This was the worst upgrade I have ever experienced with Apple. As it was, with Time Machine backup, it worked to restore but I lost files even though. I would like to know when will it be safe to upgrade if ever. I felt like a test-case for Apple. I should have stayed with my system because it worked great before and very fast. This upgrade is not for everyone and I want to make sure people are warned. Some may experience nothing but good, but for me it was not!!
my system: MacBook Pro
Memory: 8 GB
back to : 10.9.4
processor: 2.2 GHZ intel core 17
symptoms after upgrade to Yosimite: extremely slowness to crawling. Adobe creative software suite upgrades would not install and stalled at 42%
I fixed all that by reverting and using cleaner application from Adobe.

Yosemite/OS X Mavericks: Revert to a previous OS X version

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.

Thinking of Going From Yosemite BACK to Mavericks!

Greetings All-
First of all, I'd just like to thank this community for being the most helpful group of professionals one could ever turn to in times of distress or need.
I have spent hours of time seeking to find why my wifes 15" MBP - which we upgraded to Yosemite, has been nothing but trouble ever since. The infamous "Spinning Colored Wheel" is a hourly sight along with a freezing system, and extremely slow processing! I have sought out everything I possible scenario and also backed it up in case I found something that erases all cache, cookies, etc OR brings me back to using Mavericks!
Looked into the typical Anti Virus / Malware software and if truly required, what settings to put MBP on for safer surfing & operation and to be honest I don't really know if I should be using the Mac Firewall and FileVault (or what Security settings should be ON vs OFF)
On my trusty 17" workhorse I stayed on with the 10.9.5 OS and have no issues of the sort thankfully. I also really didnt like the new layout of Yosemite while using hers but just cannot put a finger on what it is I don't like. My question is - are there any members who had troubles like these or simply didnt care for it and chose to return to Mavericks? And better yet - HOW easily can one convert their OS Backwards to a previous one too?
Thanks for any advice on these topics and hopefully I can solve her matters!

First, reverting to an earlier Mac OS X from Yosemite is not difficult if you have a TimeMachine backup of the system:OS X Yosemite: Revert to a previous OS X version If not, things get messier because you have to erase the hard drive and reinstall the Mac OS X version and then reinstall all of the applications. Data will be lost unless you make a backup on an external drive before starting the erase process. If her MBP came with Mavericks installed at the factory, you can restart holding the Command+Option+R keys (this takes a good internet connection) which puts you on the Apple servers. Then use Disk Utility to erase the hard drive and then Install Mac OS X to get Mavericks back. After that the issues are your applications and other data.
As to her slow performance, you can check what is running in the background pretty simply by getting a copy of etrecheck, from etresoft.com, it is free, and that will show all processes that are running and you can look for obvious culprits like MacKeeper, Anti-Virus software, cleaning software - the usual bad actors. Latest version is: http://www.etresoft.com/etrecheck
I have had no issues with the latest Yosemite running on an Early 2011 15" MBP, but I have a lot of memory and that usually makes a big differences.

How do I revert from Mavericks to Mt. Lion?

I have tried the suggestions contained in similar threads without success. My configuration may be causing problems. Here is my configuration and the pathway I would like to use:
As shown below, I have a MacPro early 2008 running OSX 10.9. I have an iPhone 4S running iOS 7.0.3. I back up Time Machine to an external hard drive and also to a separate internal hard drive that occupies one of the bays on my Mac Pro, but it is NOT the same hard drive on which Mavericks resides.
Before migrating from Mountain Lion 10.8.5 to Mavericks, I did a final backup of Time Machine to each of the two drives mentioned above. I then proceeded to install Mavericks 10.9. For me, this was a mistake. I normally wait until at least three updates have occurred before moving up to the next OS X offering. The many flaws I have encountered in the way Mavericks currently operates have funally exhausted my patience and I must revert to 10.8.5.
I would like to make the change using Time Machine for both the Mountain Lion operating system and all of the applications and documents. If I were going to reinstall Snow Leopard 10.6.8, I would start by reinstalling the OS using the DVD which I have and then I would restore the apps and documents from Time Machine. However, neither Mavericks nor Mountain Lion have DVDs. I believe that they both can be installed by Time Machine, but this is where I run aground. I don't know how to make it happen. I have tried and have been hindered by popup windows telling me I can't change the Applications. I can't go on from there. I would prefer to dowload from the hard drive version of Time Machine rather than the external drive for the simple reason that the internal hard drive is faster. If that is not advisable, I am certainly willing to go with the external drive. It is my understanding that I can restore Mountain Lion directly from Time Machine along with all of the documents and other stored items such as Applications, Library, etc.
I have tried to do this, but can't seem to get the hang of it. I need a tutor who knows how to do the job using this path. Assistance will be greatly appreciated.

A SIMPLE METHOD FOR REVERTING FROM MAVERICKS BACK TO AN EARLIER OS X VERSION
There were so many caveats and side issues included on various instructions that didn't apply to me that I thought it was a bit confusing. However, I got the idea that restarting while pressing down the option key would give me access to the Recovery drive. I tried it and it gave me several choices. The top one was irresistible. It says "Restore From Time Machine Backup." I had done full backups using Time Machine to both an internal hard drive on my MacPro and an external hard drive just before installing Mavericks. I clicked on "Restore From Time Machine Backup" and selected the external drive since I wasn't sure that the internal drive would work. The internal backup drive is faster, but I felt the external drive was a safer bet. A window came up asking me to choose which backup I wanted to use. I picked the one I made just before installing Mavericks and it went to work. It took a couple of hours to finish, but as it restarted and Mountain Lion 10.8.5 appeared on the screen, I was totally relieved. I feel liberated. Everything works. No wacky glitches to say "gotcha!"
When you consider all of the written instructions, many of which are very difficult to follow, this very simple method of restoration is amazingly easy. I hope it helps others who are considering moving to OS X 10.9. Just get a good external Time Machine backup of your present system before you venture.

Unsupported RAW files in Mavericks from Yosemite ?

Does anyone know if it's possible to get a camera profile from Yosemite and use it in Mavericks ?
I'm specifically looking for the canon 7D mark II profile, which is not available in Mavericks, but is in Yosemite.
(I can't upgrade to Yosemite as my Mac is not supported)

I was hoping there could be some tricky workaround by reusing a profile inside /System/Library/CoreServices/RawCameraSupport.bundle/Contents/Resources/Plungins.zip
but i don't know if they are compatible and what name to look for.

How do you reinstall OS X Mavericks from Yosemite?

Ever since I installed Yosemite, I've had nothing but trouble. I have basically no memory, I can't watch my videos, I can't edit movies, and the format is just nauseating. Any information would be greatly appreciated. Please help!
