OS X :: Don't Have Permissions To Access Macintosh HD

Aug 31, 2010

My MacBook has had song big problems, and all I can get it to do is boot up with the Mac OS X install disk, or the DVD I put ubuntu on earlier. Otherwise I get the grey screen with a folder and question mark flashing on the screen. I am unable to reinstall OS X because of the error, so we (I and a guy on this site) have worked out I need to backup my files using ubuntu, format the computer and then reinstall the OS.

I don't have an external hard drive, but I found ubuntu allows me to use my iPhone in the same way. I have backed up most of my files now, but I cannot access the main folders;
Desktop, Documents, Downloads, Library, Movies, Music or Pictures and I get the following message:
"The Folder contents could not be displayed.

You do not have the permissions necessary to view the contents of "_____".

Another problem is to put these files back onto my newly formatted MacBook, I will have to access my iPhone using ubuntu, and I can't put items onto the Macintosh HD because I get the message; "Error while copying to '(name)'.

OS X :: Macintosh HD Permissions Changed To "no Access"

May 18, 2009

White MacBook running Leopard gets stuck at grey start up screen with spinning wheel after the Sharing & Permissions for everyone on the "Macintosh HD" was changed to "no access". I booted off of system disk and ran Verify Permissions and that gave me the message " Disk Utility stopped repairing permissions on "Macintosh HD" because the following error was encountered: The underlying task reported failure on exit" Archive and Install failed as well. Tried booting off of Disk Warrior CD but MacBook kept restarting while holding down the C-key.

Luckily I did a back-up last week using Time Machine. But I would still like to refrain from a clean install if I can help it. There were a few new files and installs that occurred after the last back-up. Albeit not a major problem. So now I'm trying to change Permissions for the HD using Terminal. Current settings listed below.

total 12
d-wx-wx-wt@ 2 root admin 1024 May 18 06:50 .Trashes
--w--w--w- 1 root admin 4096 May 18 06:50 ._.Trashes
drwxrwx---@ 47 root admin 1666 May 18 06:57 Macintosh HD
lrwxr-xr-x 1 root admin May 18 06:32 Mac OS X Install DVD

But when I use the "chmod 755 Macintosh HD/" command in the Volumes Directory I get "chmod: Macintosh HD/: No such file or directory. Are their 3 spaces in that command? Or am I missing something else?

IMac :: Not Booting - Probably Due To Changed Permissions In Macintosh HD

Dec 19, 2010

I am guessing that is because I did something stupid.. i changed the "Sharing & Permissions" section in my Macintosh HD Get info window. To be more specific, I changed the Everyone's permission to "no access". I tried booting with the Mac OS install disc and doing the HD recovery from the Disc Utility but it didn't changed anything. In fact there is an error every time I am trying to do "Repair Disc Permissions", while the action "Repair Disc" is completed with no problems.

MacBook Pro :: Can't Access Macintosh HD

Jul 4, 2012

I just bought a new 15" Macbook Pro last two days, and today I used Boot Camp Assistant to install Windows 7.

I devided 250GB of my HD for Mac, and the rest for Boot Camp Windows. During Windows 7 installation I maked format the boot camp partition and resized it to 50GB so I have unallocated 450GB free space. After Windows 7 installation completed, I used Disk Management on Windows to create another new partition with FAT formatted. Then I restarted my Macbook Pro to use Boot Camp Assistant to download Boot Camp Driver due to I forgot to download at the firs time.

But I didn't see my Macintosh HD and even Recovery HD on the start up disk selection menu (Hold Option during start-up)I try all things from Apple Support page even try to recover via Internet (Command + R during start-up) and make a Lion Recovery Disk (USD Flash Drive)I have another Macbook run Lion too so I try everything that should work but it's still not work.Finally, I log on to windows and format all Macintosh Partition for a hope to clean install the new Mac OS X Lion, but it still not work.he last thing I haved tried was to exchange my new Macbook Pro hard disk with my unibody 2008 macbook and try to install new Mac OS X Lion. After completed install all new Mac OS X Lion 10.7 (.0), I put the macbook pro hard disk back to the new Macbook Pro and try to boot it but it shows up the Stop Sign.

I have installed windows 7 on bootcamp, and currently running max os Lion currently i am having issues accessing the mac os itself. When i turned it on and off or restart it, it always gives me a bootup screen that said Mac OS Utilities, just like the picture in this link : [URL]I tried restarting it several times, it does not boot up my Macbook, to my desktop. I trist the windows it works just fine. Then i tried recovering it 3x, which each takes 6-7 hours to do it. and it still always keep booting up the same thing over and over again.

OS X :: Changed HD Permissions - No Access

Aug 26, 2010

I have 5 partitions on 3 harddisks. While installing Snow Leopard on one of them I Lost access to ALL of them. By using the Installer DVD I managed to fix the Snow Leopard one but the rest are locked. I can't change permissions even as an admin, tried Terminal, nothing works, I'm getting desperate (and tired-It's 2:20 in Sweden now). The symbol of the HD in the info shows a HD with a padlock on it! Is there a Terminal command to unlock it? I have never used Terminal until this happend. If I don't reply at once I'm probably in bed but I hope somebody has helped me when I wake up.

MacBook Pro :: Set Permissions On 2nd HDD - Unable To Access

Jul 3, 2010

I changed the permissions on my 2nd HDD in my optibay, and now I cannot access the drive. A little lock is displayed with the icon, and when i try to access it is says "you do not have permission to see its contents."

I changed the permissions in the first place because I formatted my primary SSD drive and was having trouble gaining access to some folders on the secondary drive. I got tired of setting "read and write" for each and individual folder, and so I clicked on the small drop-down menu with the gear that allowed me to set it for all the folder within that drive. I set "read and write", and after about an hour it finished processing that command. However, after it finished, the permissions read "custom" instead and I was denied access to everything on the drive.

OS X V10.7 Lion :: Time Machine Restored 'Macintosh HD' Inside 'Macintosh HD'

Jul 3, 2012

After reinstall of OS X 10.7.4, I restored an older copy from Time Machine backup. I want to completely replace the current "Macintosh HD" folder with the folder that TM put inside it. I created a separate user account, that did not exist before to do it. Do I need to create a root account? Is there an easy way to copy /Macintosh HD/Macintosh HD/to/Macintosh HD/?

MacBook Air :: Accidentally Set Finder Sharing And Permissions For Everyone To No Access

May 4, 2012

I have a relatively new MacBook Air.  In reviewing the sharing and permissions settings for the Macintosh HD and for user known as "everyone", I changed the setting from "ready only" to "no access" thinking that this would block access from other users (like other family members).  Well, it did, but I'm part of "everyone" and now have no access to my Air.   

I have tried rebooting and accessing Safe Mode (Command/Shift/V) and I can see the status information as the machine tries to lauch in Safe Mode, but then the screen turns white leaving me with no interface through which I can launch Finder and correct my stupid mistake.

I accidentally removed my access to my hard drive in the "get info" page. On the bottom where it says 'you have custom access' under sharing and permissions I removed myself (clicked the little minus sign). Now I can't open anything and the desktop is complete empty. How do I turn my access back on?

Software :: Change Permissions Whenever Access And Change By Another Account

Jun 6, 2009

I've been changing the permissions on some of my folders and files in my normal user account so they can be accessed and changed by another account. Problem is, I have a program that saves new files into a particular folder. When it saves the new file, the permissions are the default, meaning I have to change them myself in order to make them writeable by the new account. So my first question is - is there a way to make my first user account always save files with a set of permissions that I specify?

My next question is - what should these permissions be? Both of the accounts are admin accounts. Should I therefore set group to be 'admin' and give rwx permissions to the group? Or is it possible to set owner to 'admin'? Can a file be owned by a group? Looking forward to your answers! This UNIX stuff is fun!

OS X :: Repair Permissions Isn't Repairing Permissions

Mar 29, 2009

Using OS X 10.5.6

When running Repair Permissions in Disk Utility, it reports that there are errors and that it's fixed them but if I run it again, the same errors keep appearing.

I've noticed that the current permissions on the errors are lrw-rw-rw- which I assume means that they are symbolic links and not the actual files which Disk Utility is expecting. Any idea what's going on?

Mac Pro :: Macintosh HD Nearly Full?

Apr 22, 2012

The default 'Macintosh HD' hard drive on my Intel Mac Pro (OSX10.6.8) is almost full and I'd like to clone it to a new larger capacity drive. To keep things simple I will remove the existing drive and keep it safe as a backup. I understand that I can clone the drive to a new one and make the new one bootable using something like Carbon Copy Cloner or the Apple Disk Utility but I just have a couple of quick questions. 

Firstly I believe I must partition the new disk in Disk Utility using a GUID Partition table. What about the naming of the disk? Again to keep things simple I would like the new disk to be named 'Macintosh HD'. 

Regardless of what I name the new disk when it is initially formatted/partitioned will the cloning process also copy the 'Macintosh HD' name to it? Can you have two disks with the same name connected to the Mac Pro at the same time during the clone process? 

Secondly, will the cloning process in the Apple Disk Utility automatically make the new drive bootable or are there further steps required after the clone is made? 

Finally, if I use the Apple Disk Utility to create the clone should I do this from the original Snow Leopard DVD that came with the Mac Pro or should I use the latest version that is on the installed Mac OSX?

OS X :: Macintosh HD Accidentally Renamed?

Aug 29, 2010

The name of the Macintosh HD has somehow been changed to a tiny little circle with an "x" it. I think this may have been done accidentally, but I also would like to eliminate the possibility that it indicates some sort of problem. Of course I know how to highlight the icon and select the naming area and just rename it, bit does anyone know if the little circle with the "x" means anything other than someone just accidentally renamed the Macintosh HD somehow?

OS X :: Using External USB HDD On Macintosh And Windows

Nov 10, 2009

I am buying a Western Digital (probably) External Hard Disk Drive today. It will either be 250GB or 320GB, depends on how much money I'm going to have with me. I wanted to know what the best way to format it is so it can be 'read and write' on both Macintosh and Windows in the same time. But if that's not possible, then at least Windows only (Win7) since that's what I use for games and now games are in huge sizes, just got Call of Duty 6 and it's like 11GBs.

OS X :: Trying To Change Icon Of Macintosh HD

Dec 10, 2009

I was trying to change the icon of my "Macintosh HD" on my iMac. I'd done this earlier on my Macbook Pro, and I had the same problem as I'm having now. I eventually got it done on the 'Book Pro but I don't remember what I had to do. When clicking "Get Info", in the left-top corner the icon isn't there. It's blank and says "png". Why does the icon not show up? I can't copy-paste it, and it's stuck that way.
