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.

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 :: 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.

OS X :: Changed Permissions For Entire HDD

Sep 20, 2010

I right clicked on my Macintosh HD icon, chose get info, then changed permission to read & write, and applied it to all enclosed items. Then I restarted my MacBook and it wouldn't boot. It would just hang on the Apple logo boot screen with the spinning thing. So I did some research online and saw that I would have to wipe my whole hard drive and start over since I applied read & write to all enclosed items. I put the OSX disk in, and booted to it. Before I went to install a fresh copy of OSX, I tried to repair disk permissions instead. To my delight, it worked. I was able to boot like normal. But now I am having some strange problems.

-When I load Firefox, the bouncing icon will be all jumpy.
-When I log into Skype, the log in sound will only play halfway.
-The most weird and major problem is the no setting will save at all. If I add a new bookmark in either Safari or Firefox, then quit and reopen the program, it will not be there. If I change my home page, the setting won't save after I quit out. If I remove something from my OSX dock, then log out then log back in, it will be back.

OS X V10.6 Snow Leopard :: Admin Permissions Have Changed

Apr 15, 2012

When I upgraded to Snow Leopard, somehow my permissions have become affected and now when I log in as administrator, I am blocked from accessing folders that the administrator should be able to access. I think that my Administrator account details got deleted or changed to 'unknown' during the upgrade when I had to wipe my whole computer to load the new software. I now get the message: 'The folder “CrashReporter” can’t be opened because you don’t have permission to see its contents.' I can then go into 'Get Info' to change the permissions by adding my admin account (which is not there for some reason) and specifying 'read and write' and then it works fine. However, I have to do this individually for each and every folder and subfolder to make the files work properly.  Is there a way of having the computer change all the access permissions to accept my admin name and password again? (So I don't have to change the permissions one at a time on each folder?)

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.

Info:MacBookPro, Windows7

MacBook :: Can't Access Macintosh HDD When Booted

Jun 3, 2012

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. 

i tried re-installing the OS, but its always giving me message, "this mac os lion is damaged, cannot be installed in this computer" something like that. i've been trying to fix it a day or so, it still wont boot up my Desktop.. I tried restaring it and choosing my disk "Macintosh HD" but it still gives me a recover screen. I also tried pressing the option key then choose my disk, and it still doing the same thing.

Hardware :: Changed Network Set Up - Lost All Permissions On Time Capsule

Nov 30, 2008

I finally got around to changing the way my wirless devices are set-up; instead of using time capsule as my wireless device, I went back to using the linksys wi-fi router (which I'd used prior to time capsule, but now set up as WPA2 if it makes a diff?) with the intent of putting time capsule in another room with my 1TB iTunes library hanging off it. All seemed to work well but I initially had a problem with the TV keep dropping the wi-fi connection. Now connected via ethernet to the linksys, no problem. iTunes streamed okay but I couldn't seem to get time machine to make a back-up - just prepared forever (overnight, still no joy).

So I noticed today that I seemed to have lost permissions on both iTime drive and time capsule. I managed to fix the iTunes drive by connecting direct to my macbook and running disk utility then adding myself again via sharing (hip hip for MRoogle), but I cannot do the same with the time capsule. Even with airport utility and connected via ethernet I can't even get the configuration up - just spins out until it throws an error. Anyone have any ideas as to what I'm doing wrong - I'm assuming it's me as this all worked in the previous set-up...

OS X V10.7 Lion :: Changed Permissions On Startup Disk - Now MBA Hangs Up On Boot

Apr 17, 2012

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?

OS X V10.5 Leopard :: Changed Contents Of Receipts Folder Now Permissions Won't Repair

May 29, 2012

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?

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 :: Files Disappear When Using "Get Info" - Permissions Can't Be Changed?

Jun 9, 2010

I have several files in my trash that cannot be permanently deleted due to permissions errors, but when I click 'Get Info', the file disappears, only to reappear when I close and reopen the trash. It's very frustrating! My main goal is to just get these files off my external drive and be done with them! Super Empty Trash does nothing.

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

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.

OS X V10.7 Lion :: Changed Wheel Group Properties To No Access At Top Disk Level

Jun 2, 2012

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...

My girlfriend changed the user's name and the problems started (iMac wouldn't remeber system settings and denied access to some files and catalogs).

OS X :: Unable To Access Network Window / Network Settings Changed By Another Application

Dec 11, 2009

My neighbor has an IMac with OS 10.4.11 installed. When I open System Preferences and select the Network icon, the Network window comes up but it is overlayed with a message that states: "Your network settings have been changed by another application." When I click OK, this same overlaid window comes back.

The only way I can get out of System Preferences at this point is to do a Force Quit. In other words, because this overlaid window appears, I am unable to access the Network window to look at TCP/IP settings, make changes, etc.

Next I went into System/Library/Preference Panes/Network.prefPane(more info) to look at the application that appeared in the "Open with" field. It stated "System Preference." I replaced this with a new "System Preferences from the Applications Folder, but the same thing happened - even after I rebooted the computer.

Please let me know how to solve this problem so I can access the Network System Preferences properly.

Thank you.

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?
