There is actually a faster method, where converting the binary file is NOT required. Using the "defaults(1) command, you can edit the binary file in-situ. To set the umask to 002, you would invoke defaults like this: sudo defaults write /Library/Preferences/.GlobalPreferences NSUmask 2 and it inserts the following key/value pairs: <--snip--> <key>NSUmask</key> <string>2</string> <--snip-->The key is getting the umask value set correctly. The argument that I provided "2" is the decimal representation of the octal value of 002 (note that I have not tried to pass it the octal equivalent, which may or may not work) 077 would be 63 decimal 022 (default) would be 18 decimal etc, etc, Here is how the conversion works for 2 (decimal) to 002 (octal): |......o c t a l.......|...|d e c i m a l| 0 x 8² + 0 x 8¹ + 2 x 8° = 0 + 0 + 2 = 2 0 x 8² + 7 x 8¹ + 7 x 8° = 0 + 56 + 7 = 63 etc, etc... For the octally challenged, here is a conversion table for you: http://www.ascii.cl/conversion.htm Beware of the layout, however since their formatting is a bit sloppy (the octal numbers run into the binary and it makes the two appear as one giant digit (at least in my browser, Firefix)...

Under OSX, it's been a strange issue because the umask seems to be at a default of 022 (rw-r--r--) for all guis, [..] SOLUTION 1) Edit the file /Library/Preferences/.GlobalPreferences.plist 2) Add the lines: <key>NSUmask</key> <integer>2</integer>10.4.x UPDATE ------------- Following up to this thread on how to adjust the global umask on a Mac OSX machine. It would appear in 10.4 they started making binary versions of the XML files, and in some cases I've seen the umask value already set inside the file. So to set the global umask in 10.4.x, use these steps: 1) Edit the /Library/Preferences/.GlobalPreferences.plist file. If it's in binary format, quit the editor without saving, then run this: plutil -convert xml1 /Library/Preferences/.GlobalPreferences.plist ..that will convert the file into an ascii file. (You might want to save the old file, just in case). See 'man plutil' for more info. 2) Search for an existing "NSUmask" and change the <string>002</string> value to <string>000</string>, eg: BEFORE: <key>NSUmask</key> <string>002</string> AFTER: <key>NSUmask</key> <string>000</string> If the above two lines don't already exist, add them within the outer <dict> section of the file. This should affect all users on the machine that change is made to. You may also want to check if the user's own .GlobalPreferences.plist file in their home directory (eg. /Users/fred/Library/Preferences/.GlobalPreferences.plist) doesn't have any settings that might override this value. |
