Dodgy xv dvd permissions problem

hey all - don't jump to conclusions - readme carefully
what i can't do
play dvd as user with xv
what i can do
play ANY dvd/video as root
play dvd as user with another video output
play avi from harddisk and cdrom as user with xv
so, user can use xv as long as it is not with the dvd. i think there is a permissions issue but i dunno how to start looking
all playback is set run from /dev/cdroms/cdrom0 based on Sarah's suggestion and the fact that i couldn't get the symlink to remain after reboots????

To read a dvd, your player has to have read access to the block device. In this example, it's probably /dev/cdroms/cdrom0 (or 1 or whatever) and that is a symlink to something in /dev/ide/...
You need to set your /etc/devfsd.conf to give group/world read access to that device. I create a disk group and put anyone I want to be able to access the dvd into that group, then give the group read access to the device, but you can do it however you want.

HT2963 How can I fix permissions problems now that I have changed permission on my HD and have error code -8076, locked disk or ....?

iMac v10.7.4. Error message says disk is locked. Permissions set for read/write admin (me). Can't open iTunes, Mail, photoshop, adobe bridge [you do not have permission!]. Fonts in Word are unexpected, not cambria. Used Disk utility to repair permissions (ran it twice, once before reinstalling photoshop from DVD; once today). Situation worsening.

Permissions problems occurred after I downloaded Lion update on 6092012. I believe the problem originates with Lion (see the 19 pages of posted problems in the community). I have now talked with Apple Support rep and an Apple Genius. Have reinstalled Lion from the HD Recovery disk. I see some improvement but also at least one new problem: TimeMachine apparently has lost all backups, don't know how or why. Will have to take machine to a mac specialist or wait for Mountain Lion to arrive. Lion is a bad cat.

New SSD, but LOTS of Permissions Problems

I have installed a new SSD drive alongside my 1.5TB spinning drive on my 24" 2009 iMac 2.93GHz. I used Carbon Copy Cloner to move my everything except my User account over to the new 60GB SSD.
I originally assigned the User's folder on the old drive using the Users & Groups User/Advanaced Options window to change the Home directory, but that resulted in unrecoverable crashes and I had to reinstall the OS three times until I finally left my old files on the old drive and just ran my Applications on the new drive, keeping everything else on the old drive, but not connected as a "user".
However I've run into a ton of permissions problems with every file I open and many programs that access thos files and have done this so far to fix it:
Run resetpassword on both drives in terminal when I rebooted to the Mac OS X install disk (Lion).
Run Drive Genius' repair permissions utility.
Run Disk Utility's repair permissions.
I continue to have issues with every file I use on the old drive, so I'm at a loss to fix this in place. I did read somewhere that moving your files to another drive, then reformatting then moving back can by default fix any permissions issues, so am considering this as a fix:
Move files on the old 1.5TB drive, folder-by-folder to an external drive.
Reformat the "old" internal 1.5TB.
Recopy everything on that external back on to my 1.5TB drive.
Run Repair permissions on both drives.
This isn't fast or elegant, but I want the issue fixed. I don't want to have to open "info" on every file I use and check and change every file permission before I can use it!
Any input on whether or not this is a real fix or is there a better one?
Thanks!

May not have anything to do with your issue but often
the master disk image loaded on your hard disk before
it leaves the factory has old (and/or odd) bits of
code on it. Plus the transfer is done as fast as
possible. Last they do not zero and erase the drive
before putting the image on it, so if there are bad
sectors they may not be marked as such and may be in
use (& corrupted).
As you are having trouble get your data off as best
you can, erase AND ZERO the drive, repartition, and
only then re-load from your Install DVD.
Takes extra time but better safe than sorry...
Well, I have no real means to do this now as I sold off my G5 already
Also, how do you zero it?
When I reformatted my G5, I picked the option to wipe and reinstall, yet when I did, the drive name and bluetooth names were still my old ones! - Not encouraging.
In any case, its clear I have a software problem, so looks like I'll need to burn a zillion dvds and start over .
Thanks.

Permissions problems with Shared files

In my office of two users I have set up file sharing between two Macs, one is is running Snow Leopard 10.6.2 and the other (a PPC machine) is running 10.5.8 (The Leopard Machine was migrated over from a Tiger Machine by doing a fresh install of Leopard and then using Migration Assistant to move the user account off of the Tiger Machine).
Occasionally, I need to send files to the Leopard Mac from my Snow Leopard machine, so I connect to the other Mac's Shared folder, navigate to the Drop Box, and pop the file in.
Looking at the file on the other machine, it comes through as Read Only, ie. if I Get Info on it, it says 'you have custom access' and lists users as Nobody: Read Only; (Unknown): Read Only and Everybody: Read Only. These permission remain like this once the file is copied or moved out of the Drop Box.
I've had a look at the Sharing Prefs on both machines and they are set up to have the admin account as Read and Write and Everyone as Read Only - the Drop box is then set to have the admin account as Read and write and Everyone as Write Only (Drop Box).
The permissions problems happen in either direction, whether copying from machine A to machine B or vice versa.
Can someone help me fix this.
Thanks

Thanks for the tip. Once the other user vacated their Mac last night I ran the commands but...
Unfortunately, I still seem to be having issues with files being 'read only' on the Leopard machine. If I send a file from the Snow Leopard Mac to the Leopard Mac's drop box, it shows up with what looks like read/write access for 'nobody', 'everyone' and 'unknown user', but if I open the file, work on it and try to save via an app's save dialog, it says the file is Read-only. In the words of t'internet: W T F?
I ran your commands on the Snow Leopard machine too, and curiously, if I send a file from the Leopard machine to the Snow's Drop box, I CAN read and write to the file.
One thing that troubles me is that My User name is now listed TWICE in the list of permissions I get (My User Name): Custom Access and (My User Name) Read/Write. That seems odd.
no, that's normal. this happens because of the ACLs.
Something similar is happening on the Leopard machine too.
I created a fresh user account on my Snow Leopard Machine to see what the default permissions should be and I get other entries in the permissions list that aren't present on either of the two Machine's main user accounts. Users such as 'Staff', for example. Frankly, I'm lost.
I've read somewhere that there could be permissions problems on machines where user accounts have been upgraded from Tiger to Leopard as is the case with one of the machines in question.
yes, that could be. we can fix that if necessary.
I've also read that I can do a complete reset of ACLs by using the Reset Password utility on the Leopard installer DVD. Would this be worth a go, and could it cause more problems if it doesn't work?
yes, you can try resettings ACLs on the leopard machine using the leopard install disk. however, the acl reset utility on the leopard disk is somewhat buggy and sets wrong groups on everything it touches. therefore after you are done with it, reboot normally and run the following terminal command
sudo chown -R `id -un`:`id -gn` ~
you'll have to enter your admin password (which you won't see). that's normal.
If you can bear it, could you please help me some more. Thanks very much.

Maybe you have hardware problem.
I would try running the extended version of your Apple Hardware Test.
It's not perfect but may flag something.
A more thorough test for RAM is the free Rember.
Use the extended test also.

Permissions repair complete

My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac or an Apple refurbished iMac to save money.

I used Terminal to change the permissions on the folder in question. I followed the instructions in this article:
iTunes: Missing folder or incorrect permissions may prevent authorization
In my case, the folder was there, so I needed the command to change permissions on the folder, not to create one. I was hesitant to use Terminal b/c I know that if I made an error I could wipe out my hard drive or render my computer unusable. So to be SURE I didn't make an error, I carefully copied the command from that page and *pasted* it into Terminal. Also, before I could do anything in Terminal, I had to go change my admin password (it had been a blank password before and that's not acceptable for making changes in Terminal). I was just super careful when entering my password or doing anything else while Terminal was open (making sure I didn't accidently hit the spacebar or another key, etc.) And it fixed the problem right away.
What was confusing for me was that the iTunes error message said to change permissions in the FINDER, which is what I was trying to do. It didn't mention Terminal. What would really be helpful is if Apple included a link to a page like this in their error message.

Disk Permissions Problem on External HD Accessed Wirelessly

Hello,
I recently purchased a LaCinema Connect MiniHD and have been using it with a Western Digital 750Gb drive (formatted Mac OS Case Sensitive, non-journaled). I also recently bought a D-Link DWA-125 wifi dongle to use with the LaCinema.
I can access and read/write to the drive without problem when it connected via USB to my computer or to my wife's laptop. However, when I try to trasnfer to it wirelessly over the network (i.e. when the drive is connected to the LaCinema which, in turn, is on the network) I receive error messages when I attempt to transfer files to certain folders (including the "root" folder). What is interesting is that the folders that I can transfer to appear to be ones that were created on my old work computer, with an earlier OS version (definitely not Snow Leopard).
I suspect that I have some sort of permissions problem, but "Repair Permissions" is not available to me for this drive in Disk Utility.
I have plugged in the drive into my computer and have reset the permissions so that the "owner", "staff", and "everyone" are able to read and write for all folders and sub-folders, but it has not solved the problem.
Any advice would be greatly appreciated.
Thanks,
Graeme.

Eric,
I, too, apologize for the delay in posting. I have been away from the discussions for a rather extended period.
Well, any NTFS formatted volume will only be accessible to you as read only. No, this is not something new, but has always been the case. To make matters worse, I have heard that Windows no longer provides any way to create a FAT-32 volume; one must use OS X to format the volume or use a third-party application in Windows. This information may be incorrect, but I wouldn't be surprised if it is true (we're talking about Microsoft, here).
If you can copy any data on this drive to some other location, then use Disk Utility to format it as FAT-32, the data can then be copied back and it can be used to transport the data cross-platform, with read/write access on both ends. Is this a possibility for you?

Same problem here.... Luckily--and it was pure dumb luck on my part--I only updated two computers before catching this problem.
I'm curious if you've found any resolution to the problem? If so, could you post it here? If not, I'll post anything I manage to find....
