How do I take mountain lion off my MacBook Pro
I recently updated my 2009 MacBook Pro to mountain lion and it has been a disaster. My computer gets very hot, up 170 degrees F and it freezes up and beacballs. I tried to reinstall snow leopard but it will not reinstall and freezes up during the install process. When I run a disk utility it says my hard drive is fine. Can you return your computer back to snow leopard?
Did you Wipe the drive of Mt Lion before you started the Snow Leopard install? If not that is what you have to do.
You can't install an older operating system over the top of a newer version.
Can you return the system bac to Snow Leopard? YES you can.
Boot the system from the Snow Leopard DVD and open Disk utility. Re-Partition the drive as ONE Partition. Then exit DU and start the install of SL.

The Mountain Lion graphic icon is ghosting now and says "Paused".Did you Wipe the drive of Mt Lion before you started the Snow Leopard install? If not that is what you have to do.

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.

I bought mountain lion for my macbook pro and I'm trying to install it and it says there was an error and I need to boot up but I don't have any other start up disks to boot up with. Are there any suggestions of how I could get my computer started?
Hold the Option key down and restart. Select one of the drives that comes up and hit the Return key.

I've just installed Mountain Lion on my Macbook pro and cannot now open Preview. I've partly solved the reading of PDF documents by installing Adobe Reader, but Preview is also stalling the log out process. Any suggestions how I might solve this annoying trait would be most appreciated. Many thanks.

I have an Epson scanner that is apparently no longer supported because it is a PowerPC app. It's a very good scanner that worked fine until I upgraded to OS Mountain Lion on my MacBook Pro. Any suggestions on how I can continue to use it?
For that model, Epson has this information:
ICA Scanner Driver
07/17/12
Description: The latest Mac OS X ICA scanner driver for your Epson product is available only via Apple's Software Update. Here's how to get it:
1. Connect the all-in-one or scanner to your Mac and power it on.
2. Select the menu, then Software Update.
3. Follow the on-screen instructions to install the available updates.
Note: Software Updates may find multiple updates for your system. You may choose to install all or some of the updates by clicking on Show Details.
Compatible Systems: Mac OS X (v10.8.x) -
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.

What day in July is Mountain Lion included on MacBook Pro purchase?
What day in July is Mountain Lion included on Macbook Pro purchase?
There's no telling when a Mac with Mountain Lion pre-installed will hit the stores. It all depends on when the factory begins installing OS X 10.8 on the drives. The Mac's at the store aren't necessarily 'old' - maybe a month old at best - and it's just going to take some time for the factory to catch-up with the latest OS.
I don't see any reason - other than not having an Internet connection - to put off the purchase of a Mac until it has Mountain Lion on it. When I bought my MBP in March, it was manufactured in the fifth week of 2012 - February - and I had to do some Software Updates. OS X 10.8 is just another update which you can choose to install or not. If you bought any Mac after June 11th, it's a free update.
You can wait to make a purchase after the stores get machines with ML installed but I don't see the point.

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"? -
I tried to airdrop Civilization V from a Macbook Pro with Mountain Lion to a Macbook Pro with Lion and it doesn't work. Other apps have but Civ V has not.
Likely because it's a not self contained and/or it's game and copy protected, so install it via the developers instructions instead, which likely means it will have ot be uninstalled off the first machine, the developer contacted for a new license key before installing on the newer machine.
If you want it on both machines, you will need to likely buy another license.
Most developers are fine with transfering license between machines, you have to contact them.
They just want to make sure it's only on one machine so they are not getting robbed. -

If i download the new OS X Mountain Lion to my Macbook Pro that has Snow Leopard, will i lose my apps and downloads (such as: Microsoft word, powerpoint, excel, oovoo, skype) and will i lose all of my pictures/documents and information?
I should just change the OS and leave all your apps and data alone. That said, if any of your apps are old and use Rosetta (ppc apps), they won't run under Mountain Lion.
Make sure you take a good Time Machine or Clone backup before you convert.
You can check compatibility of your apps here:

I just downloaded Mountain Lion for my MacBook Pro from the App Store. I was curious if it is possible to downloand Mountain Lion to my iMac without paying the $19.99 fee again? Not trying to be a cheapskate, just curious if App Store purchases are universal like iTunes Apps.
You can re download Mountain Lion for free on all your authorized Macs using the same Apple ID used for the original purchase.
How to re download apps from the Mac App Store:
Open the App Store. From the menu bar click Store > Sign In
Click Purchases from the top of the App Store window.
Select Mountain Lion.
Then right or control click where you see Installed then click Install.
