Reinstalling Lion on 2012 Macbook Pro - taking forever
I erased the macbook and have been trying to reinstall Mountain Lion and am stuck at "22 hours & 45 Mins Remaining". Any suggestions?
Welcome to the Apple Support Communities
Note that the computer has to download OS X from Apple, so this may take hours. If you feel that it's stuck, restart your computer, start into OS X Recovery again (holding Command and R keys while your computer is starting) and reinstall OS X again. If you can, connect your computer to the router by Ethernet (this may make the download faster)

How to get install disk for lion on 2012 macbook pro
How do i get a reinstall disk for drivers and lion as well as ilife so i can install a new ssd drive in my computer
As Niel said, you have to install OS X through OS X Recovery. Respecting to iLife, if your Mac came with DVDs, you should have it on the Applications DVD that came with the Mac, and if it didn't come with DVDs, open App Store > Purchases, and install iPhoto, iMovie and GarageBand.
Then, if you want, you can download OS X from the App Store instead of using Recovery, so you can burn the installer onto a DVD or USB drive with Lion Diskmaker, so you won't have to redownload OS X each time you want to reinstall. As you have a Mid 2012 MacBook Pro, it will only work if it came with OS X Lion and you upgraded to Mountain Lion -
hello, I am trying to reinstall os x lion in my macbook pro mid 2012, from my recovery disc, and its imposible because every time I have problems to download de installer or something that is required to do that. what can I do?
When you do get it downloaded, before you do anything else, save the Lion installer - make a copy and put it somewhere safe. you can then reuse, make a clean install and other things.

Yes I strongly recommend making a clone you can boot from in addition to use TimeMachine.
Carbon Copy Cloner will also offer to copy and make a Recovery partition on the 2nd drive. -
I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing. I have absolutely no clue what to do here. Any help is greatly appreciated. Thank you.
- Currently if I boot it up there is a flashing folder icon with a question mark in it. I am assuming this means there is no OS because I wiped the SSD and tried to reinstall Mountain Lion
- When I hold Command+R, it prompts me to Choose Network... the problem with this is the wifi constantly is disconnecting. The Retina 2012 does not have an ethernet port so i have considered buying the attachment then returning when done.
Once again Thank you in advance.
Best.There is nothing to do if you don't have a reliable Internet connection unless you have a copy of the Mountain Lion installer application from when you first installed it.
Install or Reinstall Mavericks or Mountain Lion from Scratch
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.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless. -
could a 2012 macbook pro from the factory been loaded by the factory with both Snow Leopard AND OSX Lion?
I think MBPs stopped coming with Snow Leopard installed as of the late-2011 models. That's when OS X Lion started being pre-installed on MBPs. Some earlier MBP models (2010, early-2011) had a firmware update to allow Internet Recovery (command+option+r) which would allow a reinstall of OS X Lion (purchased from the App Store) with the purchaser's AppleID/password.
I don't believe SL would even install on a 2012 MBP. -
I'm trying to reinstall Mavericks on used Macbook Pro. When I log in to my Apple ID, it says it was not the same ID used to purchase Mountain Lion. I need to change user/admin as a lot of the folders and apps are in Chinese!
The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model. Look it up on this page to see what version was originally installed.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. If you don't have the media, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
Once booted from the disc or in Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.
After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, buy it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able toauthorize it under your ID. In that case, contact iTunes Support. -
Hello,
I have installed mountain lion on my macbook pro ,but it made my mac very slow. Would someone please tell me how to uninstall this one and reinstall snow leopard? I tried to do it by my original CDs but macbook pro didn't let me to do it.
ThanksIt would be easier to just fix whatever is making your machine slow.
I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

HI, SO I BOUGHT MOUNTAIN LION ON MY MACBOOK PRO TRYING TO UPGRADE FROM SNOW LEOPARD, AND WHILE TRYING TO REINSTALL THE OS SETUP AS IT SHOWED IT COULDNT BE VERIFIED, I CROSSED OUT MOUNTAIN LION FROM MY PURCHASES, ITS NOW GONE, DO I HAVE TO BUY IT AGAIN?
Please google search for "Mountain Lion disk crash" before upgrading you mac pro. You might need to replace you Mac hard drive after the upgrade.So many people had the same problems including me.
Be aware of the Mountain Lion upgrade problem. -
I want to reinstall OS on my 2012 MacBook Pro. It shipped with 10.8, but now runs 10.9. Can I reinstall straight to 10.9, or do I have to reinstall 10.8 and upgrade again to 10.9?
Best to install 10.9 straight up. If you still have your OS 10.9 downloaded file you can use that, or you can go to the app store and download it again. It will be in your previous purchase history. Or you could even upgrade to 10.10. If you want to start from scratch you will need to boot from USB or DVD and initialise (erase) your internal HD. To do create a bootable USB thumb drive with OS 10.9 or 10.10 follow this guide

Does OS Lion 10.7.5 support Airplay mirror of Apple TV 3? I can't find the option in Setting>Display on my mid 2012 MacBook Pro.
I've rebooted all 3 devices, still does not work. Both Apple TV and MBP are on the same wifi. And the Apple TV AirPlay option is on. Can someone help? Thank you.About AirPlay and Airplay Mirroring
AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

I have a 2012 macBook Pro 13" and the option "Use audio port for" does not appear at all in the sound menu. why is this? im running mountain Lion 10.8.2
Because line-in has been removed.
It does allow for an Apple headset with mic., but I don't know if it would work with third-party ones.
You'll need to use a Griffin iMic or similar to use line-in via a USB port.
The same goes for the 15" retina, the newest MBA and the new iMac (whenever it finally arrives). -
Reinstall Mountain Lion on 13" macbook pro retina
hi! i am trying to reinstall mountain lion on my new 13" macbook pro retina, however, i cannot proceed and i encounter the message "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." please help!
I've called Apple Care and they learned me to the following in order to complete a clean install from Mountain Lion on a MacBook Pro Retina (otherwise it won't work): http://support.apple.com/kb/PH11273
But, like Clinton said, shouldn't your rMBP come with Moutain Lion on it? And if so, why can't you upgrade to 10.8.2 because I could (with software update) - but my problem was to clean reinstall ML on it from the App Store (that you stil can't do with a rMBP btw).
And a small question off-topic: How long is your (average) shutdown time on your rMBP 13"? -
2012 Macbook Pro won't boot from CD and freezes in single user mode
I'm rebuilding a macbook pro. Everyting was fine until I tried to install Snow Leopard from the disk. It goes to the Apple symbol no spinning wheel and you can hear the drive working for a few seconds but then stops. I've also tried booting to sinlge user mode but it just freezes after Loading System\Library\Caches\com.apple.kext.cahces\Startup\Extensions.
I've tried resetting the PRAM as well.If you have a 2012 MacBook Pro, you can't install Snow Leopard because it's not compatible, so it's normal that you can't start OS X.
Now, you have to install OS X Lion or Mountain Lion again. Hold Command, Option (Alt) and R keys while your Mac is starting to start into OS X Recovery, and reinstall OS X. After reinstalling OS X, you will be able to use your computer.
You can't run an older OS X version than the one that came with your computer, because of some reasons:
1. The hardware isn't compatible.
2. The firmware restricts the installation of older versions on the computer.
3. It's illegal: Apple doesn't allow you to install an older OS X version than the one that came with your computer, and it doesn't mind the method you use (a "normal" installation or a virtual machine) -
How many times can I install mountain lion on my macbook pro?
My Macbook pro came with lion pre-installed. However, I bought at a time that allowed me to update to mountain lion for free. Therefore, I wanted to know if I will have to pay to re-download mountain lion on my Macbook pro if I have to restore the system to its factory settings?
No, since you have already "purchased" (even if for free) 10.8 on the App Store with your AppleID, you own it, so you can reinstall as much as you want.
