File Vault changes permissions?

I've written a C++ application that will be used by both Windows and OSX clients. The app is simple and console based and is distributed as a simple binary file, compiled separately for Windows and as a Universal OSX application. I edit with AquaEmacs and compile from within using a simple makefile. I don't think any of this is relevant, but it might so I share it.
I've sent the file to one of my OSX testers who happens to be using an Intel Mac (MacBook) running OSX 10.4.10. The file is named "Sartain" and I send it as a file attachment to an email, not it .dmg format. Just for insurance, I use chmod to set file permissions to universal r,w,x (sudo chmod 777 Sartain). With this background, here is the problem I'm trying to sort out.
My tester seems to receive this file as "Sartain." (note the period). Moreover, when he tries to execute the file (./Sartain) from his home directory, he gets "permission denied". I had him check permissions and the received file has stripped off all the write and execute permissions, leaving him only with universal "read" permission. The only way he can run the program is to use chmod to reset permissions.
He is not a Mac sophisticate and so I don't really know what to have him check. He reports that he DOES NOT use virus protection on the machine but he has FILE VAULT turned on. This is the only thing I can think of that would produce this problem. I've scanned the net widely but cannot find conclusive evidence that FILE VAULT changes permissions on received files, but I'm stumped where else to look. He uses a Novell email client and I suppose that his mail server could be stripping off the permissions, but I'd like to rule out FILE VAULT before having to phone his sysadmins to find out what the default setting is on their mail server.
Any thoughts here would be welcome. Thanks for your help.

File Vault Stripping Permissions

I don't think this problem has anything to do with File Vault or a virus or anything else on the recipients machine. Rather it's due to trying to send the raw executable file through the e-mail system. File permissions are not contained within the file and hence would not be transferred when you attached the file to an e-mail message.
The addition of the "." (period) on the end of the attachment name may also be a side effect of sending through the mail system.
I think you'd have better luck putting the file in a disk image and sending the .dmg file. The file should definitely keep it's permissions within the dmg and I think it will also retain them once the recipient drags the file out of the dmg.

Illustrator files automatically changing permissions to read only

My Adobe illustrator file are changing to read only by themselves. This becomes annoying because i'll have to unlock the file, change my own permissions, and then try to re-save the file. Otherwise... I'm stuck with the "Error -54" code every time i open up a file and try to save it.

How do I change permissions on many files at once?

Hello!
I recently had a large hard drive crash, and, long story short, I got all my data back but now have a different user account on a new hard drive. The permissions on all the files on the computer are fine.
However, I am a recently graduated film student and use an external drive to edit video. When I tried to open up Final Cut Pro and work on a project, I was told that the program couldn't work because I didn't have "write" access to my scratch drives. I changed the permissions on the relevant folders and can now open the application fine, but can't actually edit because ALL the medi files don't give me full read/write access.
I can change them all one at a time, which requires I enter my password for each one, but this would take a few days of work to complete.
My question is: how can I add my user account with read/write permission to many files at once? I've heard this can be done with Terminal, but I'm not sure how.
Please give me step-by-step instructions if you can! I have never used Terminal before! I am not a techie, but I want to be, and I learn quickly!
My computer specs:
15in Macbook Pro, early 2008.
System 10.5.8

In the Finder's Get Info window, under permissions, you can click the little gear icon and set the "Apply to encoded items" flag. Then when you change permissions, it will apply to everything underneath the selected folder.

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.

After trying to change permissions on my computer so others on my network can grab files, my external Hard Drive has a lock on it and I can't access files. I've tried repairing permissions, logging in under another Administrator account, using Terminal to fix the problem, downloaded BatChmod but nothing works… Any other suggestions? I have an Imac running OS10.6.8.

There is suddenly a lock icon on my external backup drive!

Thanks C F McBlob but I recursively changed the permissions of my Music directory meaning every file and directory beneath it, as well as the directory itself, had the write permissions added.
I used "chmod -R u+w ./Music" and chmod -R g+w ./Music" to do it.
Alas, no cigar. :-(

I a owner and administrator. I can't change any file permissions. Help tells me to 'get info' on a file, them click on the lock icon to enter password. The lock icon is not present on any files I 'get info' on. How can I change permissions

I attached an external drive to my macbook pro for backup purposes. I found that the device is 'read only' for me. I read that I could change permissions by selecting 'get info' for a item and clicking the lock icon to submit my password. The lock icon is not displayed on any 'info' window for any file on my macbook, much less the attached drive. I am the only user and administrator as far as I know. What steps can I take to change permissions? Thanks. My 1st post.

How can I tell? The 'get info' window has no lock and under sharing and permissions, on says 'you can only read'. I did a get info on the Macintosh HD and it had a lock on it but said I could only read, for what that it worth.

How do you rename, or change permissions on many files?

**Note** there are SUDO commands here that can potentially wreck up your system. If you have questions about this stuff, post in the forum or ask someone verbally to help. The sudo command can really cause problems if you're not entirely sure what you're doing.
I had an issue a while ago where I had to rename about 400 pictures all in the same folder. They were all named by a students PEN #. I needed an incremental number starting at 001.jpg. I was hoping to figure out a script either in apple script or in terminal that would do the job. I called a friend of mine at another school with my problem (he's a windows guy) and he had this great idea.
First of all, using terminal list all the files.
The command is simply "ls" without the quotes.
Select all the files that the ls command outputs and copy it. (command c)
Next, open up excel or numbers or any spreadsheet program, select cell B1 and paste the list of files in question.
When I type SPACE below, I mean hit the space bar.
Now comes the fun part.
In cell A1 type mv SPACE
In Cell C1 type SPACE
In Cell D1 type 001
In Cell E1 type .jpg
In Cell F1 type the following.
Fill down each of the columns to the bottom of the list of file names.
A
B
C
D
E
F
G
mv
pennumber1.jpg
001
.jpg
=CONCATENATE(A1..E1)
mv
pennumber2.jpg
002
.jpg
=CONCATENATE(A2..E2)
mv
pennumber3.jpg
003
.jpg
=CONCATENATE(A3..E3)
mv
pennumber4.jpg
004
.jpg
=CONCATENATE(A4..E4)
mv
pennumber5.jpg
005
.jpg
=CONCATENATE(A5..E5)
Now Select all of column F and copy it.
Open up terminal and navigate to the folder that's containing all your files to be renamed.
Hit paste and press enter.
This will paste in the contents of each cell in the f column followed by an enter.
Voila!
Now, if you wanted to change ownership of a set of folders, you could use the same process.
I'm assuming that the folder's that your changing are home folders here. In other words, the home folder name should be the same as the shortname of your user.
It might look something like this:
Navigate to the folder that conains your user folders. **CAUTION ----SUDO AHEAD*** This command can BREAK YOUR COMPUTER if you're not careful.
Type: sudo -s
type your password.
Copy the list of Folders from terminal.
Paste them into some column way on the right in excel or numbers or whatever. Maybe column F or something.
Now, in A1 type chmod SPACE        and fill it down all the way.
In B1 type -R SPACE         and fill it down all the way
In C1 type =F1 SPACE       and fill it down all the way
In D1 type =F1       and fill it down all the way
In E1 type =CONCATENATE(A1..D1)        and fill it down all the way
The spreadsheet might look like this:
A
B
C
D
E
F
chmod
-R
=F1
=F1
=CONCATENATE(A1..D1)
thor
chmod
-R
=F2
=F2
=CONCATENATE(A2..D2)
incrediblehulk
Again, just copy and paste column E into terminal and poof! It should work!
*Note, it might be a good idea to run a trial on a folder that's not important to you before you start. These commands you're running can wreck things up pretty good. So ensure things are set up properly before hand!

In the Finder's Get Info window, under permissions, you can click the little gear icon and set the "Apply to encoded items" flag. Then when you change permissions, it will apply to everything underneath the selected folder.

I can not open documents I get a message that says To view or change permissions, select the item in the Finder and choose File Get Info. help

I have a mac with os X. I have saved documents and photos on my computer and am now not able to open them. I get a message that tells To view or change permissions, select the item in the Finder and choose File > Get Info. I do that and it is not locked. confused. help

In the Info window it's this:
Do you have read and write privileges?

I can't move files or folders or delete files without authentication. Also, it doesn't appear that I can change permissions?

I can't seem to move or delete files or folders on my MacBook Air mountain lion system. It doesn't appear that changing permissions works either? Any ideas?

Back up all data now.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. If none of this is meaningful to you, you don't need to worry about it.
Step 1
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Be sure to select the whole line by triple-clicking anywhere in it. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select Utilities ▹ Terminal from the menu bar. A text window opens.
In the Terminal window, type this:
resetpassword
That's one word with no spaces. Then press return. A Reset Password window opens. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

Show File Info window disappears before I can change permissions on it.

I am trying to access a Pages document in a file sharing arrangement, but Pages won't allow me to access it. I checked permissions and need to add permissions, but the Show File Info window closes before I can do anything to change permissions.

J,
Not to dodge the issue, but you are having an OS problem, not a Pages problem. If nobody comes along here with an explanation, you might do well to post in the Snow Leopard discussion area, assuming your profile is correct.

Solved - How to take ownership and change permissions for blocked files and folders in Powershell

Hello,
I was trying to take ownership & fix permissions on Home Folder/My Documents structures, I ran into the common problem in PowerShell where Set-Acl & Get-Acl return access denied errors. The error occurs because the Administrators have been removed from
file permissions and do not have ownership of the files,folders/directories. (Assuming all other permissions like SeTakeOwnershipPrivilege have been enabled.
I was not able to find any information about someone successfully using native PS to resolve the issue. As I was able to solve the issues surrounding Get-Acl & Set-Acl, I wanted to share the result for those still looking for an answer.
Question: How do you use only Powershell take ownership and reset permissions for files or folders you do not have permissions or ownership of?
Problem:
Using the default function calls to the object fail for a folder that the administrative account does not have permissions or file ownership. You get the following error for Get-Acl:
PS C:\> Get-Acl -path F:\testpath\locked
Get-Acl : Attempted to perform an unauthorized operation.
+ get-acl <<<< -path F:\testpath\locked
+ CategoryInfo : NotSpecified: (:) [Get-Acl], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.GetAclCommand
If you create a new ACL and attempt to apply it using Set-Acl, you get:
PS C:\> Set-Acl -path F:\testpath\locked -AclObject $DirAcl
Set-Acl : Attempted to perform an unauthorized operation.
At line:1 char:8
+ Set-Acl <<<< -path "F:\testpath\locked" -AclObject $DirAcl
+ CategoryInfo : PermissionDenied: (F:\testpath\locked:String) [Set-Acl], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetAclCommand
Use of other functions like .GetAccessControl will result in a similar error: "Attempted to perform an unauthorized operation."
How do you replace owner on all subcontainers and objects in Powershell with resorting to external applications like takeown, icacls, Windows Explorer GUI, etc.?

Final Thought: There are great non-PS tools like
Set-Acl and takeown which are external to PS & can also do the job wonderfully. It may be much simpler to call those tools than recreate the wheel in pure
code. Feel free to use whatever best suits your time, scope & cost.

Im just glad to see others have the exact same permission changes, which as the other replied stated, makes me not worry about it.
I just don't like Apple changing permissions so they can "read" anything on my computer they want - when Im on iTunes for instance.

On my mac, when I try to import certain music CDs (not all) I get this message "You dont have write access for your iTunes media folder or a folder within it. To change permissions, select your iTunes media folder in the finder, and chose file get info"

I am not sure how to fix this and it is driving me crazy can anyone help?
Thanks.

Hi folks,
I've had this issue for a year now and I've read this and several similar articles on how to change permissions for you iTunes Media folder and all that enclosed stuff.
Well today, I got brave and dove into this issue once again and to my surprise I have it remedied.
Before I kept going to my side bar folder 'Music', then located the iTunes Media folder ( I have several libraries).
This time, I went from (your mac)HD, directly to the 'Library', scrolled to 'iTunes' and reworked my permissions there by creating a new user... (ME). While at it, I adjusted 'Administrator from and back to, 'read and write', gave myself, 'read and write' and left other users as 'read only.'
I then applied to all enclosed folders with the 'gear wheel,' locked the whole shabang up and proceeded to install several old CD's which refused to import in the past.
RECAP:
HD/Library/iTunes set permissions for YOU to 'read and write,' then apply to all enclosed folders.
BTW: those enclosed folders are likely to be all the albums you've collected previously.
Perhaps, the 'iTunes Media folder' description from previous instructions kept people looking in the wrong place.
In any case, I'm up and running and I hope you will be too.
Thanks,
PS
