OS X :: Contents Of This Disk Can't Be Changed Mac Couldn't Be Installed On This Disk
Oct 4, 2009
I tried to install Snow Leopard.
I got the error, "The contents of this disk can't be changed. Mac OS X couldn't be installed on this disk."
I restarted, to boot from the startup disk, not the CD.
And now it just goes to the grey screen and shuts off.
Pressing "C" or "Opt - Command - P - R" or holding down the Power button for a while and then restarting, or trying "Command - V"..... none of it works.
The machine just goes to the grey screen, the wheel spins, and it turns off.
I was upgrading from Tiger to Snow Leopard (I asked a worker in the Apple store and he assured me it was okay to do so) and about 15 minutes into the installation I got a message saying "Unable to install. Please retry". Then when I retried it says "The contents of this disk can't be changed. Mac OS X couldn't be installed on this disk."
I have a black MBP and it is Intel based and I fit the system requirements
I ran installer then went to disk utility and pushed disk repair. it ran and indicated in green that no repairs were necessary. i then went to startup disk and only the Diks and network startup showed up but no hard drive. i also open computer to make sure was not wet muddy due to leak in cooling system but all was dry
I know this has been disccused ad nausium many places, but in reading 100s of posts Ive just confused myself and was hoping someone could help me make sense of all I've heard.I have a ibook g4 and use a WD 500gb external hard drive to keep all my music/pictures etc.Last night when I was moving files around (I dont think it was actually in the process of transferring files when this occurred, but there is a slight chance it was) I accidently hit enter instead of shift which told my computer to open all of the 1000+ folders that I had selected (DOH!) after working for an hour it seemed to be all frozen so with concern I turned the computer off and restarted.Suprise suprise, my external will no longer mount. - Disk Utility recognizes it but says there was an error on exit.Tim
I want to erase the hard disk. Holding the Option key when restarting the macbook, and enter the Recovery HD, selecting the Disk Utility. Click the hard disk name, and select Erase tab. Click the Erase button, a message displayed: Disk Erase failed. Disk Erase failed with the error:Couldn't unmount disk.
I keep getting a pop up saying my start up disk is almost full, or that my iTunes library couldn't be saved, but I've still got a quarter of hard drive available on my new iMac. OmniDiskSweeper shows that most of the memory goes to my iTunes Media and Pictures/videos, but that shows just 61GB of hard drive used for Users. What could be using my hard drive space that doesn't show in OmniDiskSweeper?
Tonight i was working on a report in MS Office 08, and it was all fine and what not until one point i got some error message saying that the disk was full and i couldnt save it and to change the saving location. Anything this is on the main drive where i have ~40gb's left. So i put my USB Drive in to save it on that and it gave me the same error it wouldnt save on anything it just keep saying Disk Full.. Does anyone know what that is? Clearly its some sort of error/bug as i restarted the macbook and downloaded a picture and saved it on my desktop with no problems after the reboot. Im running mac osx 10.5.6
I have 2 Macbook Pro's 15".I want to clone one onto the other.Do I copy the contents of the disk via Migration Assistant? I tried this and saw that it wanted to add the contents, not replace them..Do I use the Snow Leopard Install disk and go to Utilities? I couldn't see what I needed to do.
I use a NAS for backups and external storage.At some time in the past week, my backup operations stopped working, and I think I have tracked down the source of the problem. Somehow, an "extension" got added to the disk name (I did not do this and I am not sure how it happened).The disk name (Cosmos) has not changed, but when right click and choose "get info", in the "Name and Extension" section, the disk shows up as Cosmos-1. Unfortunately, the name is greyed out and I can't change it.Does anybody know how I can remove the -1 extension and change the name back to Cosmos so that my backups see the disk again?
My G5 is completely full. Can I transfer my iphoto contents to an external HD? Using Time Machine won't help because it only backs up my photos so I can't add more to my iphoto library.
Or, is there a way to make iphoto an external HD application so the photos are only stored ion the external HD?
I've just transferred my data to a new computer and now need to erase the hard drive on my old one.. I've tried Disk Utility, increased the security, and tried 'erase' but I keep getting an error message "couldn't unmount disk". I've gone into Partitions and tried deleting the HD there as well but I get the same message. I just want to get the computer securely wiped and would like to keep Lion as the operating system.Â
I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?
Suddenly my Disk Utility changed to Danish and the paper/pencil/ruler icon is in it's place. How can I change my Disk Utility back to English?
Noticed this after a back-up last night. How can I change my DU back to English? I can't use it for repair permissions, partitions etc. because I don't read Danish.
I messed up, I changed my "Wheel group" properties to No Access ( or something other than the default) at the top level of my startup disk "Macintosh HD".now my computer won't start up, I just get the spinning wheel of death.I also am in Thailand right now, so I cannot go to a Genius at an apple store, nor do I have startup disks available.So I was hoping there was a way to change back the properties of my disk (Volume) in single user mode (via Command +s) during startup, i.e. can I do a chmod command on the Macintosh HD listing under the Volume Directory.Or where do i fix this? Is it fixable without startup disks, etc...
I have a 2.3 GHz Intel Core i5 Mac book Pro, I changed the hard disk once, and now when I tried to update it, it always says "An unexpected error occurred" And the only button for me is the "Restart button" (Remember, I always have my Wifi on). Is it because of the hard disk changing or because of something else?
"Mac OS X cannot be installed form this disk" never herd of it before until it happened to me just minutes ago. attempting to install leopard onto a PowerMac Dual G5 from a FireWire drive.
I installed bootcamp and ran Windows 7 on a single hard disk.
After using MP for a while, I decided to use SSD as my main drive and re-installed Mac OSX on that drive. Now I cannot boot onto the hard disk with Windows 7 bootcamp.
Is there anyway to recover the hard disk wholly?
BootCamp Assistant keeps telling me I have to erase the whole partition and create a new one
I work in an office where we've picked up a few new MBPs. These machines have Snow Leopard and I'd like to install it on my machine running Leopard. Is there any way that I can install 10.6 on my machine using the Disks that came with the new machines?
my HD fried so I just installed a new 250GB HD about 20mins ago. It's not showing up on the disk utility. It shows one for 4.8GB but not the 250GB? bad connection? I'll try to reconnect it again. It's a Seagate, same brand as I took out of my 1.66 intel Mac mini.
The full message is below. I already have updated to 12.2.7 and running the latest Mac OS but suffering continual Entourage crashes, which I'm hoping this will fix.
Office 2008 12.2.8 Update can't be installed on this Disk. A version of the software required to install this update was not found on this volume.
I have a macbook pro that is just a few weeks old. It came with a 500GB disk, exchanged it to a 120GB SSD disk. I installed OSX and windows and it worked fine for a few weeks. Then I burned an ubuntu 10 x86 cd. I shut the machine down and was going from windows to osx so I had the alt button pressed down while starting the machine. It took a while, but after that I got a folder with a question mark. I booted with a windows cd in, and it never reaches anything, just loading windows and freeze.
I booted ubuntu with the cd I burned and it finds a disk but sais its unparitioned. I have booted osx installation dvd and it also finds the disk but sais its unpartitioned. Repair drive is grayed out. I'm a windows admin and know my way around windows, I have just worked with mac for a few weeks so I am not familiar what I can do and what repair tools there is for the mac filesystems.

I have an iMac that is less than a year old and I have very few applications installed other than what comes on it. I recently received a message that my startup disk was almost full. I keep all of my media on an external drive, have an apple time machine that stores the backups. I purchased the Space Gremlin and there is nothing on the hard drive that shows it's taking up that much space. The 500 GB hard drive shows only 11 GB free.
Info: iMac (21.5-inch Mid 2011), Mac OS X (10.7.4)
I restored from backup OS X 10.5.8 Leopard using Time Machine to a brand new drive. After manually migrating some data to the newly restored boot drive I accidentally replaced the /Library/receipts folder with an out dated receipts folder. The problem is there is no way to get the proper receipts folder back so I'm stuck with a receipts folder filled with permissions that are not in sync with the list. I'm assuming this blunder is causing the error: The underlying task reported failure on exit, every time I try to repair permissions. I need this boot drive to be stable and want to avoid installing from DVD the OS from scratch. The drive checks out ok with every test accept repair permissions. The system is running VERY stable now on this brand new WD Caviar Black 1 TB drive. Do you think it's safe to clone this drive even though repair permissions won't work anymore?
I have a external HD which has always worked fine under snow leopard. Since upgrading to lion I keep getting the following message The identity of the backup disk has changed since the previous backup.The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk. And after this the drive disappears from the desktop appearing agian only after restart. What can I do do rectify this? Delete and re-intialise the drive?
After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.
When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?
Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.
