OS X Mavericks :: Can Downgrade Back To Mountain Lion On MacBook Pro?
Sep 9, 2014
I'm trying to dual boot my Macbook Pro (2010) with Windows 7 to run some software that is not Mac compatible. I have encountered one problem after the next, but most recently, my disc drive has stopped reading discs. I had originally gone from Mountain Lion to Mavericks as an upgrade, and my disc drive worked fine - but due to an issue with the Windows 7 installation, I had to completely wipe my computer and start fresh - booting Mavericks from the Cloud directly. This appears to have knocked out my disc drive and try as I might, my computer will not only refuse to read external optical drives, but it will accept discs, not read them, and repeatedly spit them out a few seconds later.
I was looking for a solution - and I'm not sure exactly which route to take. I could downgrade to Mountain Lion and hopefully restore the functionality of my disc drive to install Windows 7 and upgrade my OS after the fact OR I could find a way to repair my disc drive. The issue is most definitely software and not hardware.
Ideally, I'll walk away from this with a partitioned MacBook Pro with both Windows 7 and Mavericks installed. I don't even necessarily need my disc drive to work once Windows 7 is installed.
I upgraded to Maverick on a previously owned Macbook Pro OSX 10.9.4, and when trying to get updates, the previous owners's Apple Id shows and their password is required. what canI do?

downgrading their macbook pro from mavericks to lion (or, if not lion, to mountain lion)? I have a late 2013 mbpro with rentina (model 11,2).
I am no interested in any flame wars, but I, personally, despise mavericks. I have several other macs I have worked on for years and have been extremely satisfied with snow leopard. I explored installing sl on my mbpro, but it isn't possible to the newer hardware on the mbpro.

I am trying to use Business Objects through the web and unfortunately Java 7 is not compatible. I was able to downgrade to Java 6u65 (Java 1.6.0_65) but I really need update 45 to get Business Objects to work. Terminal code and/or a download that will allow me to pull out Java version 6u45? (Java 1.6.0_45)?
I've been on here trying several other's codes and it says permission denied or "unable to find any JVM versions matching 1.6.0_45"
Could that mean I don't have version 6u45 available to me period?

I now can't use three programs I desperately need since my upgrade. How do I downgrade back to 10.6? The disk that came with my iMac won't let me load the old system.

I have been using OS X 10.9.4 for a while and wondered if i could go back to mountain Lion ver of operating system as a couple of my older devices don't seem to have drivers available. e.g. printer and scanner ?
I have an iMac with two accounts (say A and B), where A is Admin and B isn't.
I have a MacBook Air with one account (say C), where C is Admin.
Both iMac(A) and Macbook Air(C) share the same iCloud userID, but iMac(B) does not.
By using the built in screensharing service of Mountain Lion (not Apple Remote Login), can I use "Back to my Mac" to remotely log in iMac(A) from Macbook Air(C) when outside of my home network? In particular, can I "log in" iMac(A) when it's not already logged in on my iMac or iMac(B) is using the machine?
How can I delete content from my Lacie Porsche Desing Mobile Drive? I am getting the message "TRASH The operation can't be completed because back up items can't be modified.
Mac Mini running 10.8.5. Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications. TM does back up the internal HD.
Have made many manual Time machine Back ups that calculated the differnce and adjusted the differnce in what was then saved. The very size of the external HD did not roll over. Yet the calculation states a entire new Back Up. Is this a permission changing issue? Or what?
I want to downgrade back to Leopard and have a question. Does erasing the HD to do an install, also erase the Windoze partition? Or everything but that?
My son's school wipes the hard drive of their computers every year when they upgrade. I made a copy of my son's entire hard drive (10.8) before turning the MacBook Pro in to be "updated" (wiped and everything replaced with 10.9.4). Now my son has told me he made Notes he needs. what files do I need to replace from the backed up version of his system? I need to know how to locate the old files that I can not access by holding the option and going to the library etc because the old system files are on an external hard drive, not an active older mac.
I assume there is more than one file. We have not made any new Notes, so I'm OK to completely overwrite the new notes files with the ones from the older version. if there is any way to simply open the notes so I can copy and paste into Word, that would be fine too.
Just moved to Mavericks. My very first action is to search for my important folders with colour. Very first question why has coloured folders been removed? This makes an Apple computer much more difficult to use. Which person suggested this change and why did they do it?

Our IT department at our ISD tells us we cannot upgrade to the Maveriks OS. It is not compatible with the rest of our software. I get a pop up very frequently to the point of being obnoxious for updating to the new OS. How can I turn off the update pop up?
MAC iOS 10.8.5
Have looked under preferences and on the update screen.
I'm trying to boot up my late 2013 15" MBP (shipped with Mavericks) using an external startup disk running Mountain Lion. I really need to use the FCP iChat Theater feature, as I need to do some long distance editing. The startup disk works just fine, I checked it on another computer, but when I restart my Mavericks mac and choose it as the boot drive, I just get a grey screen with the universal "no"symbol (circle with a slash through it).
When I use Time Machine to restore my old mails, it doesn't works, shows the backups on the right but I can't click. The Backup was made on Mountain Lion and I installed a clean Maverick.

I have a Macbook Pro Retina which cam with Mountain Lion installed, and I want to upgrade to Mavericks. However, I have a need to run some apps in Mountain Lion, as official support for those apps will not go past 10.8.5 (Avid's Pro Tools 10) and I need to be able to open archived projects.
I also wish to clean install both operating systems fresh, and do a stripped ML partition, with bare bones essentials, on the smallest partion possible. Mavericks will be the main system, and ML won't host user data, only the legacy apps. I am fine with erasing my 500GB SSD.
My current process is to install ML from the recovery partition, and use disk utility to partition before I do, then install Mavericks from a bootable USB (already made).
So my questions are these:
For ML:
1. What size partition is the minimum necessary to install ML, plus the apps and run without hitch? The legacy apps will take maybe 4GB.I want this as small as possible.
2. When I do a fresh install of ML, what apps can safely be deleted without affecting the system?
For Mavericks:
When migrating my old user account to Mavericks, I don't wish to migrate the apps, just the user settings and the data. I will make an entire backup of the user directory on a separate drive before I start this process, as well as a Time Machine backup. I then plan to migrate the account settings and data, but manually reinstall the extra apps. The reason for this is I have a lot of third party apps, and some are trials I decided to uninstall, and they all leave junk behind.
3. If I import the user account settings and data only, what cruft or orphaned files should I be aware of?
4. Are there options to cherry pick the settings that are migrated?
5. If I manually copy, for example, the mail folder, iCal or messages folder in my user library, and place it into the appropriate user folder in the new account in a worst case scenario, will there be any drama I should be aware of?
Lastly, a question of Apple ID's/iCloud:
6. Before doing this process, should I deauthorise my iTunes account, or will that be fine when migrated anyway?
7. What will happen with my iPhone when I sync to a fresh install on mavericks, will it attempt to wipe my iPhone, or is that part of the user data that is migrated?

I'm one of the unlucky owners of Macbook Retina 15" Mid 2012. I was very satisfied with this computer, everything was great, untill I installed OS X Mavericks. My computer started to have GPU Panics all the time under some "heavier" usage like watching long videos on YouTube. I googled this problem and then I saw that I wasn't the only one, many people had problems after upgrading to Mavericks. I also read that downgrading to Mountain Lion solves the problem, but after the Internet Recovery update, when you are restoring your mac, it restores as Mavericks. I read Apple instruction how to revert os x, but it requires Time Machine backup from Mountain Lion, I already downloaded ML Installer from AppStore but I don't know how to install it.
I just received my new Mac pro at work and is trying to install Mountain Lion as the OS instead of Mavericks but it seems impossible. Every time I try to boot up on a bootable 10.8 installation drive I get the no entry sign. I even cloned my old MacPro and tried to boot from the external drive, I still get the no entry sign.
I tried booting from a thunderbolt, USB and even super drive, with no luck.
I need to install 10.8 because Mavericks doesn't work with Active Directory in my company, it just hangs the system every time, we've tried many different ways to fix this but it just seems to get worst.
Any way I can downgrade a 2013 Mac Pro to 10.8?

When I want to get mountain Lion, apple store telles me that I have Maverick installed. How can I charge the M Lion version to install on an external drive?
