Changing Permissions after reinstall

I had to reinstall Leopard 10.5 on my MacPro when it would not boot and disk utility could not recover the boot disk. Now, all my data drives are read only! I can change permissions on a file-by-file basis, but that will take forever. Is there a batch command that will allow me to change the permissions on all the files in a folder or volume?
As an old Linux/Unix hand, I tried using chmod -R from the Terminal Window, but without success.

chmod -R is the correct command for changing permissions recursively but what you likely only need to change the permissions on the top level of the drives.
try the following.
run the following terminal commands (copy and paste, please)
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
you'll have to enter your admin password (which you won't see). that's normal.

ITunes no longer loads after updating to Windows 8.1. I have tried every corrective step I've found on the web (reinstall, copy files, change permissions, etc.) nothing helps. Has anyone heard if Apple is working on fix?

Itunes does not launch after updating to Windows 8.1. I've tried every suggestion I can find on web (reinstall, copy files from other directories, change permissions, etc.). Nothing works. At best I can get the licensing agreement to show and then nothing. Has anyone heard if a fix is in the works?

Hi 3backpacker3,
It sounds like you are on the right track in troubleshooting this issue. If you are having launch issues, you may find the following article helpful:

After reinstalling MAC OS 10.6.8, I config the permissions to read/write/no access, my MacMini [mid 2010] refuses to reboot. I tried to reboot in safe mode with Command+S and fsck, but after the steps to be taken, it says fscs not done, root device is read only. I also tried to bypass the Mac firmware password by taking one Ram card out and reboot the macmini while holding COMMAND+OPTION+P+R. But no luck. The macmini is not able to see the mac OSX installation CD.
Please help ??

How and where did you change which permissions? And what was the goal?
Do you have a complete backup of your system? and more importantly data files?
What happened that prompted the need to reinstall the 10.6.8 update?
The immediate road forward would be to boot from the optical drive and revert the changes you made.
What happens when you boot with the install cd and hold down C or hold down the option key?

Unable to change permissions on Hard Disk Drives after rolling back OSX Lion to Snow Leopard

Are you able to help me?
I had several problems with permissions and a series of other serious issues after upgrading to Lion, so I did a clean re-install of Snow Leopard 6.4 (from disk), upgraded to 6.8 and still had permissions problems which I have made worse by doing what I thought made sense - giving my administration user access to all hard disks and time machine back-ups. I emphasise "hard disks" because I have an iMac 27" i7 and 250GB Flash Drive provided by Apple where I keep OSX and aplication files. Thus the Flash Drive (FD) becomes the boot disk, not the Hard Drive.
Changing preferences on the Apple HD (not FD) and the Time Machine Backup HD to my user name (with administration privaleges) has had the reverse effect of not giving me access to anything other than my OSX system volume on my 250GB Flash drive! I can only see my files on the hard drives with the root user (which I have used for the first time ever to get that access). But using the root user does NOT allow me to change permissions of either my Time Machine backup disk or the Hard drive on my iMac ! Why oh why??
Googling for solutions suggested using iRepair to change permissions but that gives me a "boing" when I try with no effect - at least a "boing" is more feedback that the Apple Finder's response to my attempt to alter permissions in the "info" window!
Oh! and of course I have unsuccessfuly tried the Disk Utility as well, which does come back with errors - that appear to be "safe to ignore" from Apple Support's website!
I originally posted a slightly different message to this one to https://discussions.apple.com/message/16955471#16955471 because it appeared to have similar issues. It appears as if my problem is unfortunately quite unique!

So the background to this situation:
1. The user had OS 10.6.8 installed on one volume, while his actual users home folders stored on a second volume, this is fine but can sometimes cause issues during/post upgrade to 10.7
2. The user upgraded to 10.7 and while his home folders were still being accessed, he no longer had permission to change or modify them.
3. The user downgraded to 10.6.4 again which broke the link for his users completely.
4. In an attempt to change the permissions for his information he had the (common) mistake of changing the permissions of his root level of his drive, this did several things, in addition to negatively effecting his OS, it also locked the drive mount points in his (hidden) /Volumes/ folder.
5. the steps taken to help rectify this issue:
A. Open Terminal.
B. TYPE:
chmod -N /
chmod 1775 /
chown root:admin /
C. Reboot computer
D. Open Disk Utility.
E. Repair permissions on the boot volume.
F. Also the following commands were run on her second drive to allow him access to his stuff again:
sudo chflags -R nouchg /path to drive/
chmod -R 775 /path to drive/
chmod -RN /path to drive/
chown -R username:staff /path to drive/
Once the permissions repair is complete the Users can be readded to the System Preferences>Accounts pane and the paths to home directories located in his second drive using the "Advanced Options..." section, but due to the time the permissions repair was going to take this step will be posted tomorrow.
Also each user will require Terminal commands to make the permissions unique for each user: (this must be done PRIOR to the users being added in System Preferences>Accounts.
chmod -N /
chmod 1775 /
chown root:admin /
sudo chflags -R nouchg /path to home folder/
sudo chmod -R 775 /path to home folder/
sudo chmod -RN /path to home folder/
sudo chown -R username:staff /path to home folder/

AMDS will not install as part of 10.7 upgrade. have reinstalled many times..even manually. cannot change permissions in windows\system32\driverstore\filerepository\usb.inf_amd64_neutral_153b489118ee3 7b8

I have reinstalled Itunes 10.7 many times...each time it comes back and says that it cannot recognize my iphone because AMDS is not installed...yet when I try to install it fails...and asks me to reinstall Itunes again. It seems as though it may be realated to the usb.inf file in usb.inf_amd64_neutral_153b489118ee37b8.
I have seen where others fix the issue by changing permissions on the folder and replacing the file...the file says it is 6kb...but when I open the file...there is nothing there. I cannot even change the permission on the folder...even as an administrator. Please help!!!

Can't boot into OS X.6 after changing permissions and ownership

Hi,
I'm in the process of migrating to OS X.7 - booted into Lion I changed permissions and ownership on the other disk that I use to startup into OS X.6. I set it to "ignore ownership on this disk" and granted read and write access to "everybody". Restarting my Mac into OS X.6 now doesn't work anymore - the grey spinning circle spins forever.
Does anybody know how to fix this so that I can boot back into OS X.6? I'd be real thankful...
Best
Jurgen

Thank you for your reply. I was able to repair permissions on the failing disk using the OS X.7 Lion recovery volume - quite amazing that one can do that.
However the internal disk of the iMac that has OS X.6 on it still fails to boot.
Any other suggestions? I'm a bit desperate to use OS X.6 because a few apps that are vital to me do not run under OS X.7 (they need Rosetta).

Can't use time machine due to corruptness even after reinstalling snow lepoard how to fix?

Yes, someone stole my original apple id in 2009. Now i bought another iphone in late 2012 , Created another apple id due to Apple not being able to help me access my original apple id. Which now since 2 months ago someone or company, or bank stole my second apple id. My iphone 4s with Sprint has no celluar connection supossedly due to no internet that is what sprint said but I looked it up on apple and it stated that there is a cellluar block on my iphone4s.
So I guess I will have to go in person to Sprint so they can explain that to me and why I was lied to on the phone earlier. Back to my 2nd stolen apple id that I registered my macbook,airport express router, and iphone4s and apple TV. So who ever stole this apple id obviously took over all my mac products I had registered to it. Enough about that back to trying to use time machine....Everytime i do, my macbook just starts acting all screwed up. I bought a WD external drive for Mac but I believe someone must have claimed it too. Since there is 75gb on it that I can't access. Kind of like my Macbook stating I can't save or have access to the Root . That is another thing after reinstalling snow lepoard which works great until I update it. Which is a problem because everytime I update it to 10.6.8 All the permissions are changed the graphics look horrible and I get redirected so bad its not funny. The email account is a joke. Also I notice my stationary for email is in Spanish not sure why and on Iworks the document samples are also in spanish. Now I dont speak any other language except ENGLISH AND HAVE LIVED IN UNITEDSTATES MY ENTIRE LIFE. But my internet provider Fibrant which swears they are local shows it is in the UK also when i try to access my email for that account it states it is not safe , certificate is expired and someone might be trying to impersonate my server. Needless to say it is getting old. I had this same problem with Timewarner and Att except att would just remove my ethernet driver then laugh when i would call and ask what the problem was. Then later I find out when I had DSL that somehow the phone number they had listed was change to being a digit off from my DSL account which again they laughed and thought it was funny. Enough about that. I need to know how to get access to my Apple id. I gave up on the first one but the second one I did have access to until I registered all my apple products. What is up with every thing I have with a usb port being corrupt. I have also notice anywhere in town where I live my phone is English until I come home it is arabic,hebrew , spanish any language except English. Shouldn't I be safer in my home??????????????? But I am not I am safer in town or anywhere but my home. EVerything states international in my home and this has been going on since 2009.....No one can tell me why. My power from Duke reads that OTHER Is costing me the most $$ every month what ????? This is a joke. But yet no one can tell me why or how to fix the problem. Going on 5 years , I have been cut off from everyone I know. Can't keep contacts on a phone or email accts. They all disappear. All so I am in Eastern time zone but all my computers and tv seems to think I am in pacific timezone. No one can fix this problem either. So if anyone has any suggestions on how to fix at least one of my 5 year problems I would be grateful. I try to create a new email account but either I am locked out right after or someone turns it into an alias account which doesn't help me. When I was layed off in 2009-2010 I went back to school/college. Needless to say they took my School email acct too.
Back to my iphone 4s problem. My icloud email account gets alot of spam starting about 2 months ago and I can't stop it. I try to foward it to Spam @ me but it hasn't helped.My iphone can only connect to the internet with wifi. Sprint swears that there is not a block but according to apple there is.
About my macbook and apple ID how can I upgrade my Macbook from 10.6.3 to 10.6.8 with out all the permissions being changed and corrupt?? I have tried several times and it is always the same. I won't to connect my iphone to itunes to try to restore it but it states I have to update it to 10.6.8. When I do that my computer is alot worse off. Also how can I use TimeMachine with out my Macbook getting messed up? Something in my house has taken over anything with a usb port actually years ago and probably now something kept turning all my computers and phones or any electronic I owned it to a printer. I actually can't even use a printer in my home thats the funny thing. When I try to connect one when I used windows it stated I had no rights to it and couldn't use it. Since I switch to Mac not much better. When I try to print a test page it is all crooked and too small of half off the page. So it is upsetting that I can't use a printer but something keeps turning all my electronics into printers. If anyone knows how to fix this problem that would be great or to stop all this international stuff going on in my home that would be wonderful. I try to buy brand new pcs but soon as I start them up something had already taken over. This is with nothing electronic in my home on. Turn everything that a power switch off or unplugged it. Still I lost rights and access to anything in my home. Now if I am away from my home and try to use one of my laptops they look completely different and almost usable. Unfortunately I can't afford to move. I thought about it but I am still in bankruptcy and don't have the money. In the last 4 years I have not been able to reinstall in backups that I have created. Not sure why oh wait it states I have no rights to do that. My macbook I lost access to a week after I bought it and connected my iphone too. You don't know how many times I wish I had never backed my iphone 4s to my Macbook. Right after I could not log into it. Even used the disk to reset the password nope still couldn't log into it. Try to type the formula for resetting the password and nope it didn't work either.
Any suggestions would be appreciated---Need to gain access to my apple Id that would be a great start
Thanks, Suzanne

Garage Band '11, version 6.0.5 will not change key after new project is started

Garage Band '11 version 6.0.5: Cannot change key after new project is started.
It has always worked ok prior to this. And I have had other issues. How do I reinstall Garage Band '11?
I have looked in downloads, but can'ty find any download file. I had upgraded to Mac OSX 10.6.8 couple years back, which included
Garage Band '11, a new ITunes & new IPhoto.

Before reinstalling I'd try HangTime's fix for "oddball" problems and delete the User preferences and repair permissions, see the FAQ:
http://www.bulletsandbones.com/GB/FAQPages/OddBallProbs.html
The GarageBand 6.0.5 update is here:
GarageBand 6.0.5
If you want to reinstall, install again the GaragaBand application from your installation disk and then upgrade again to 6.05 using the link above or Software update from the Apple Menu.

I Changed permissions for every enclosed folder in my Library (not Home)

I wanted to change permissions on a fiie in my root Library (not Home Library) and clicked apply to enclosed items for the entire Library folder. Once I realized what happened (after the fact) I tried to repair permissions but things aren't working right obviously. I have a backup of the Library on my Time Machine drive that is before the snafu.
Is is possible to restore just this Library folder, and if I restored just this folder using Time Machine would it also restore the permissions as they were before I screwed up.
I'm backing up the altered Library folder to another drive just to be safe if I do need to restore.
Always learning,
Thanks

no, that's not possible because many of those items are in use while you are booted normally. you need to do a full system restore from TM from before you did this. from your last post you seem to be doing just that. and in the future NEVER ever use "apply to enclosed items" on ANY system created folders. that applies btw to things like your home folder, the library in your home folder, your desktop folder etc. use it only on folders you made yourself. apart from messing up permissions on system files like those in the root library, many system created folders like your home folder have hidden ACLs and using 'apply to enclosed items" propagates those ACLs to everything inside.
I'm backing up the altered Library folder to another drive just to be safe if I do need to restore.

Troubleshooting after reinstalling the software that came with my macbook

Hi, I'm a new user of mac products and my macbook crashed refusing to start up (it would just turn on and keep loading till froze).
I followed exactly the steps "Problem meet solution" in the little manual and had to use the Mac OS X Install Disk 1.
The disk utility repaired the HD volume (error found: incorrect block count for file flatfile.db - should have been 708 instead of 354), then still couldn't start up on HD. Did it all over again, repaired HD again (this time error: incorrect block count for file .store.db - should have been 5202 instead of 2601), but this time went further selecting "continue" and reinstalling Mac OS X from the discs that came with my macbook. Reinstalled - successfully finally - by chosing the option "previous settings archived in new file".
The only problem i had was at login ... it would not recognize my user password... which was the same one since i first turn on my new bought macbook. Anyways, i used again the disc 1, selected change my password and this time i managed to sign in with the new one (same old user).
1)NOW, question: do i have to re-update my software? Because before I had Mac OS X 10.5.2 (i always kept my computer up to date) and now, after reinstalling the software I have Mac OS X 10.5
or i should be able to reactivate them from the Previous Systems file (in this case how do i do that?
2) Can't figure still out my master password that unlocks the file vault plus i can't activate again the root admin user from Directory Utility ... i click it but doesn't do anything. Why is this and how can be sorted out?
my macbook details:
Model Name: MacBook
Model Identifier: MacBook3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 1 GB
Bus Speed: 800 MHz
Boot ROM Version: MB31.008E.B02
SMC Version: 1.24f2
Could someone help me with this? Please note it's my first time troubleshooting a computer ever and that my knowledge is not that vast in the field ... so please use simple steps/terms that i can follow.
Thank you,
Laurie

Thank you very much for answering so prompt to my questions.
1) yes, i will take all the updates. and ok, i won't touch the previous systems file
2) in regards to master password ... i tried all the passwords i ever used. not sure it's just "forgetting". Reason: as I mentioned before: The only problem i had after reinstalling the software was at login ... it would not recognize my user password... (and I add, nor the master password) which was the same one since i first turn on my new bought macbook.
As i couldn't sign in, used again the disc 1 to reset my administrator password and it did save but with the notice that i should "use the keychain access to reset the password for users login" .This time i managed to sign in with the new one (same old user). Then I went to the keychain clicked login and changed the password for keychain login. Did i do good? do I have to change something else. please let me know as don't really know.... i just follow help advice.
3)in regards to root password ... i had it also before ... using help on "security" issue ... as i connect to different networks ... i read that one could help ... please understand that i'm learning as i go, as this time i don't have someone else to do those things for me. so why doesn't it activate anymore? and why would it be better not to activate it?
4)speaking of learning, from my initial post where i posted the errors that my disk utility found ... what do u think caused my computer to freeze? i was browsing on safari facebook as well as I had both yahoo messenger and skype opened... first the messenger froze, then crushed, then i restarted it , then froze, then all the rest froze, without responding to force quit.
5) after reinstalling the software, i still have yahoo messenger and other applications.... is that safe to use now? they are still in my applications
and last 6) did I do everything correct when my computer would not start up?
thank you
laurie

External Hard Drives Changing Permissions to Read Only

Three of my USB external hard drives have suddenly changed to read only. One of the times I was trying to transfer/back-up the files from one drive that had changed to read only to another external. Suddenly the second drive changed permissions. Then after plugging a third external, that drive changed permissions. They all were working perfectly fine with my computer and I have only been using them on MACS. Any explanations? Could there be something wrong with my USB ports? Is it possible to have a virus of some sort?
Thank you!

How do I connect to my external hard drive after reinstalling OSX?

I just reinstalled OSX 10.5, then upgraded to 10.5.8 on my Powerbook. Both my external hard drive and iDisk are locked, and won't let me open them. I went to information for each disk, authenticated, but it won't let me change permissions for either disk. Help!
- ®aymond

Tom,
Thank you for your advice. I did that for the external hard drive, but it still won't let me open the drive. I'm stuck because my iTunes and iPhoto libraries as well as Time Machine all are on the external. It also won't let me open my iDisk.
Tks!
