Hi, I have a late 2008 iMac with a new hard drive. How do I install Mountain Lion from my bootable USB flash drive.
How do I install Mountain Lion to a new hard drive without having the recovery partition on it.
I have the USB flash drive with software on it but when I switch my Mac on all I have is a white screen & a flashing question mark.
ATB,
Steve.
Did you use LionDiskMaker or DiskMaker X?
Boot the machine with the option key down until you see your bootable USB stick. Select the latter, and reboot.
When the installer boots up, you will first need to choose Utilities and Disk Utility. Select the target HD device name and then the partition tab. Select 1 partition, name it Macintosh HD. Format is Mac OS Extended, and option is GUID. Apply. Exit Disk Utility and return to the installer, which will now show your newly partitioned HD as available for install.
When OS X is installed and all updates applied, press shift+command+U and run disk utility again. Verify/repair permissions and verify the boot disk.

About every 1 1/2 hours, it automatically shuts down to cool off. Is there any way to manually turn it on? Or, do they have to be replaced?
I tried that with no improvement. I think I might have to have the fans replaced. do you know if this is a particularly difficult procedure? Something wierd that I've noticed is that if I have a video on for more than several minutes, the fans comes on, and also when I am on a Skype video conference for awhile. Otherwise, the fan jst doen't come on as the intels heaten up to the point the the auto shut down kicks in...any advise? This definitely interupts my work! Thanks for your help and input thus far!

I could cry right now. After decades of being an Apple fan, something is happening for the worse and issues with every Apple product I own 2 iphones, 2 iMacs, 15" Macbook Pro, and iPad Mini (no issues here, just slow connecting to App Store and can never seem to download updates) has left me disenchanted. I do have a question about Mountain Lion but just airing out grievances.
Ok, to the point. I have the new 27" iMac that was just released. Was delivered and opened the box, turned it on, and there was a flashing folder icon. No OS, wonderful. I live in Brooklyn and not trying to lug a 27" computer onto the train nor should I have to pay for a cab to resolve this. Anyway, I tried to go into Recovery but it started doing an Internet Recovery with a download time of 9 hours. Um, no thanks. So I downloaded the latest version of Mountain Lion from the App store on my old iMac and made a boot disk onto an external via Apples instructions. Plugged it into new iMac lemon, go into recovery mode, see the bootable drive, click on it to reinstall and it gives me a crossed out circle icon and shuts down.
What am I doing wrong? I have pretty decent broadband and did start the internet recovery process now until I find a better solution online. After 5 hours, Internet recovery finished and clicked on Reinstall Mountain Lion to which it's asking me to download the OS again and with a 13 hour download time!!!! What's going on here? What was the purpose of internet recovery taking 5 hours only to download it again at another 13 hours???
Question is, is there something I should be doing differently? Is there a way to install Mountain Lion from a bootable disk? This is mind blowingly the dumbest thing I've encountered with Apple. Got a problem with your OS? No problem, just download a 4.4GB file every incident.
Thank you.You can't grab a installer from another Mac and expect it to run. The newer Macs have newer hardware which requires special drivers. If the version that boots the iMac is a special build, it won't work any other way than Internet Recovery.
If it was me, I'd take it right back. You have no idea if the OS is just corrupted, the hard drive is dead, or what. I wouldn't take my chances with it. -
I have a late 2009 iMac, with the default Nvidia 9400 Graphics card.
I was wondering what my options are for upgrading. I use Windows 7 via Bootcamp, so I need a card that is compatible/has available drivers.
This is for gaming. On the lowest settings of "Call of Duty 4", I get about 100 FPS... Was hoping to be able to play on higher resolution w/o the fps lag.
I'm not good with the hardware part of computers at all, but know how to get around the OS.In most cases the graphics cards in iMacs are Not upgradeable. They are usually soldered to the logic board. RAM is considered, along with harddrives, the only component that is upgradeable in an iMac, unlike in PC's. So basically you would need to sell your unit and purchase an iMac with a more powerful graphics card.
Hope this helps -
have a late 2009 iMac with 2.66 Ghz process, or 4GB 1067 MHz DDR3, can I upgrade to Mountain Lion?
You can upgrade to OS X Mountain Lion and Mavericks. I recommend you to upgrade to OS X Mavericks because it is the most recent version and it is free.
Open the Mac App Store and download OS X Mavericks for free. While it's being downloaded, make a backup of your files with Time Machine and check that your apps are supported > http://www.roaringapps.com
If you still want to use Mountain Lion, you can purchase it at the Apple Online Store > http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion -
I have a late 2006 iMac with new Ram installed in late 2011or early2012 . I am currently running lion. Did/ hit something while half asleep and was asked for my recovery password, I didn't know it & not sure what I did after that but it wont boot up just searches with a light grey whit -ish screen. Cant get it to clear. Any advice?
Charlies Secret Angel-Try to boot in Safe mode, see if you are able: Hold down shift and then power on. For wireless keyboards, hold down shift after the chime.

Lost my hard drive and also an Ipad, but have 7 k photos on a Touch that I need to load on fixed IMAC with a new hard drive, how do I do it. (There were more photos than the 7k, but they were saved on other drives, thank goodness). 7K pohotos on the Touch are no where else, must be saved! Just never went from a Touch to iMac. I have the cable hooked up and then what, I don't want to mess up,my last chance to save 7k pics! New Aperture and IPhoto on IMAC with no other photos loaded on the new hard drive yet.
I'd ask in the iTouch forum where there are more iTouch users there than here and they should know how to off load the photos. It might take a 3rd party app.

I'm on Firefox 3.6.8 running on a 2008 IMAC with OS 10.5.8 yet every click to move pages, from start-up, to return to Home Page takes minutes, not seconds! If I use Safari that's greatly faster on this same set-up. How do I get Firefox to be as fast ?
== Some time back, beggining with Firefox updates, at least three, or more updates ago.Thanks for the tip. I took the following steps:
1) Backed up the existing profile (presumably corrupted somewhere);
2) Deleted the existing profile;
3) Moved the existing Firefox to the Trash and downloaded a fresh copy;
4) Started Firefox (thus allowing it to create its default profile)
5) Copied the following files from the backup copy of the previous profile: places.sqlite, key3.db, signons.sqlite, permissions.sqlite, persdict.dat, cert8.db ---

I have installed the most recent version of Snow Leopard on my MAC, and I am trying to install Mountain Lion from the Apple Store. It will not install, because it says I do not have 2GB of memory, even though I have over 200GB available. Please help.
Welcome to the Apple Support Communities
One thing is the memory, and another thing is the hard disk space. You are telling me that you have 200 GB of free space on the hard disk, but the App Store is telling you that you have to install 2 GB of memory or more on your Mac if you want to upgrade to OS X Mountain Lion.
First of all, open > About this Mac > More Info, and copy "Model Identifier" here, so we can know what Mac you have got and how much memory you can install.
We recommend to buy the memory in OWC or Crucial (Crucial is cheaper and offers the same compatibility warranty as OWC) because you won't probably have any problem with the memory you buy there -

ow do I install mountain lion if I still have 10.5.8 ? Can anyone help me ?
Buy Snow Leopard - http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard - install it and do all the updates to 10.6.8 and then you can download and install Mountain Lion from the App Store (assuming that your Mac has the minimum requirements).

Removing "install Mountain Lion" from mac OSX 10.9.4.
If you're running 10.9.4 (Mavericks) and you have no need to revert to the earlier version of OS X (Mountain Lion) you can delete it. However, you may want to make a copy of it on to an external DVD or USB stick first 'just in case'. It may save you another 5gb+ download in the future if you ever did find you wanted to revert to Mountain Lion.
