OS X Mountain Lion :: Cannot Install It On Empty Drive
Aug 28, 2014
My father try to install the OS onto a newly installed internal drive on his Mac Pro. He's trying to install Mountain Lion, which is the same OS X generation as his usual boot drive (which is remaining in the system—the new drive is getting an OS as a backup boot drive).Â
The problem is that the Mountain Lion installer, downloaded from the App Store, refuses to install on the new drive. The drive, which is formatted but otherwise empty, does not appear as an available drive to install on.Â
My father believes that this is related to the note in the System Requirements saying that the Mac being installed on must already have Snow Leopard or Lion installed on it. I'm not so sure, but it's a valid question: can Mountain Lion be installed only as an upgrade, requiring an existing OS install on the actual drive being installed to?Â
My interpretation of the listed requirement is that you have to boot from Snow Leopard or later to do the install, because the installer has to contact the App Store, but the requirement is worded ambiguously enough that it could mean that the drive itself must have Snow Leopard or later on it. It doesn't make sense to me, though, for this installer to be useable only as an upgrade; there are numerous situations under which a person might need to install an OS on an empty drive.Â

for some reason I bought the infamous 2011 mac pro, and the hard drive kept having IN/OUT problems and after it destroyed half day of work, I decided to get a new hard drive, *blue WD 500g" but i have tried EVERYTHING and i just cant install mountain lion on it.
1.- i tried forcing the recovery mode so It would connect to the internet and download mountain lion but after 10 min or so i trows the -2002f error at me
2.- I tried to use the old hard drive that i put on a external hard drive reader so I could get the recovery partition but i just keep restarting the installation no reason given
3.- downloaded the mountain lion and tried to installing it on the system hard drive of the laptop trough a computer running snow leopard but dosn't let me.
4.- tried the same thing on target mode without success
5.- using the recovery partition I used disk utility to se of the partition was locked but it was not
6.- created a different partition to see if it would install it there didn't work.Â

Were is the 4GB file after the download is complete? ALSO, if I reapply the download to that machine to reset or fix corrupted system files, etc., is the downloaded install image gone afterward? In other words, does the install "clean up" and remove the downloaded install bits?Â

how to prepare for a "clean install" of Mountain Lion when it comes out. However, it's clean in theory because I want to be able to have my personal files and programs ready for ML but I am afraid for any left-overs from deleted apps since I tend to install & uninstall them for test drive purposes.

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.Â
I tried booting from a thunderbolt, USB and even super drive, with no luck.Â
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.Â
Any way I can downgrade a 2013 Mac Pro to 10.8?Â

I did a disk repair and verify disk on my external hard drive. When they were done, it created a folder called "lost+found". I deleted it and it went to the trash. Now I can't delete it. I tried the option key, using terminal and secure empty. None worked. When I unplug the external drive, the trash is empty. I connected to another mac and it appeared in the trash there and I still can't delete it. I also tired using disk utility to delete free space and that didn't work. I called apple and they stated to format the drive but I don't have enough storage anywhere else to copy the data.

I have a 4TB internal drive in my Powermac. It currently has two partitions: one that is about 270GB that is almost full, and one that is 3.7GB, that is about 25% full. Â
Disk Utility will not let me add a third one, however. The drive is NOT a fusion drive.

I have a MacBook Air with 251 GB of hard drive space, yet I only have 3 gigabytes free. I checked all my folders and they certainly do not add up to 248 GB, so where is all of this coming from? I checked my activity monitor and there is nothing that drastically large neither.

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).

l I now have to completely wipe, re-format and re-load OSX onto my iMac's internal HD, My iMac is a late 2009 27" and at present has OSX 10.8.5 loaded, ( loaded but with many miss-functions ). Prior to the problem the iMac was running OSX Lion, what version though I can't remember.I installed 10.8.5 the other day to see if that would fix things, but it hasn't. It was not a "clean install", just regular one from downloaded OSX 10.8.5.
I have run Disk Utility and TechTool Pro' 7 to try to make repairs to address the problems so far to no avail. Main problems are that my most used applications, FCP-7 Studio, Aperture and Photoshop CS5 amongst others, open but then immediately crash. I've reloaded the troubled applications, de-installed them properly with de-installation app's then clean re-installed them, but that's made no difference. They will not mount.
I reckon there must be a fault or corruption on the HD, probably caused during the Optimisation as everything was functioning well before I did that. So, the only OSX install disks I have are the original disks that came with the iMac, OSX 10.6.2 and a Snow Leopard Upgrade DVD OSX 10.6. I do have the downloaded copy of OSX Mountain Lion that I pulled from the App Store the other day and that copy is now on an external USB / Firewire 800 HD.Â
As I said I would like to be able to clean off the iMac's internal 2tb drive completely and install a fresh newer OSX. If I first have to load OSX.6.2 then upgrade via the App Store that's fine, but I'd rather just go straight to Mountain Lion if possible. Whatever works best. Getting rid of any corruption on the iMac's HD is the prime motivation.Â
All my applications and files are backed up to a 2tb LaCie external drive.The iMac has approximately 900 gb's of content onboard and the rest is free / unused space.

I am having problems ejecting the external hard drive that I use to back up my laptop. It is a 2012 MacBook Pro running Mountain Lion OSX 10.8.5. My external hard drive is a WD 2 TB My Book Studio. I use it to back up my laptop with Time Machine. Every time I try to eject my disk now I am told that "The disk (Diskname) wasn't ejected because one or more programs may be using it." I have tried some solutions like to stop Spotlight from indexing the disk and to try and turn off TimeMachine, but neither of these worked. The only thing that has worked so far is to log out of my user name and log back in with a guest user and eject it from there. This takes up a lot of time and is ultimately not really a sustainable way of working on my computer.Â

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.

I was using an external drive for Time Machine for the past year and a few months On Saturday a message came up that it failed. I tried initiating the Time Machine again but failed. I decided to get a new bigger external drive to use for Time Machine. When trying to eject the external drive I was using it gives me this message:
Would it be safe just to force eject or log out and then log back in again to eject it so I can use my new external drive?

I can't copy a Time Machine backup file (Backups.backupb) from one external hard drive to another. Both hard drives are Seagate 1TB Backup Plus. The Backups.backupb file is about 275GB. When I try to drag and drop the Backups.backupb file from one drive to the other (which I've tried three times) it to begins copy but after about 3GBs are copied I get a message that says "The operation can’t be completed because an unexpected error occurred (error code -50)."Â
I formatted (erased) the new hard drive with Disk Utility as Mac OS Extended (Journaled). Apple Support says I should format the new drive in Mac OS Extended (Journaled) "with a GUID partition," but I don't see the GUID partition as an option when I format the drive. Is this necessary, and if so, how do it do it? I'm using OS 10.8.6 on a 2012 MacBook Pro retna.Â
I also tried copying the backup files to another drive (a Maxtor HD) and got the same error message.

IMac is not booting up and I need to copy all content before reinstalling operating system. I have connected iMac to MacBook via FireWire and can see the hard rive. I have copied important files, but need to copy files in trash as well. I can not find the root to the trash on the dock when going into users or anywhere else. How do I copy files from trash across to the laptop without being able to get them out of the trash from the dock?

I have a Hitachi Touro USB 3.0 1TB external hard drive that has always worked on my Macbook. Formatted in FAT so it would work on both my PC and Mac. I can't remember exactly when it stopped working, but I think I had to reset my mac once as it stopped responding and the HDD was plugged in. After that it stopped showing up in Finder, but still appears in Disk Utility. It also shows up in Storage under "About This Mac". Â I've tried resetting my computer, ran Apple Hardware Test, and have tested the hard drive on other computers and it works fine. Just doesn't show up in Finder on my mac!!

my External Seagate Hard drive just changed to read only on its own?
I went to get info and scrolled down to the Sharing and Permissions
But there is nothing there but a greyed out : You can only read
There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE
I have recently upgraded to Mountain Lion and am having other problems as well

I replaced a 1 TB external drive partiotioned in 2 with a 3 TB extrnal drive run/store my corbon copy cloner back up and time machine.
The 3 TB drive was successfully partitioned through the disk utility and both back ups are installed and the initial back up is complete.
My question is about the 1 TB drive. I want to completely erase all data from the drive in order to use it for a different use.Â
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failedÂ
Volume Erase failed with the error:
Couldn’t unmount disk.
If I try to eject the disk
It says it will not eject becaus e a program may be using it...
The only program that utilized this partition is Carbon Copy Cloner which is not being utilized on the new 3TB drive.
I do not see where there is a option to have more than on disk chosen for this purpose so am unsure why the disk utility is seeing the old partion as still in use.

Since the harddrive of my IMac was full, I added an external harddrive to the system for my photos. I use another external harddrive for time machine back-ups (backing up both the IMac and external harddrive with my iPhoto libraries). Recently the EHD with my photo libraries crashed. I now want to restore it from time machine onto a new external harddrive, but am not quite sure how to do this.

I am backing up my data from my mac book pro for a second time. I plug in my external, and it says it doesn't have enough memory to back up my computer. I have 1 TB hard drive and used about 650 MB for the first back-up. Obviously I don't have enough to back up everything for a second time. I just want to back up the new stuff. When I go to exclude the current external from the new back up, it's grayed out. Do I have to delete the contents of the hard drive and re-back up the entire computer?
