Als je even met een zoekmachine zoekt, vind je altijd wel iets dat mogelijks een oplossing is. Ik heb geen MacOSX. Als het verkeerd gaat, ik ben niet verantwoordelijk voor ongevallen!
I'll see if I can help ... Please note I am running Mac OS 10.5.8, and this may be slightly different on other versions.
Currently, I have no way of checking for any differences.
Open Applications, then Utilities then find the file Terminal.app -- click on that to open
NOTE: In the following I will use the _ (underscore) symbol to indicate a blank space. Do No type the _ system or nothing here will work at all.
My comments will be placed between { } brackets. Do Not type in the brackets or anything between them.
Type the following in the Terminal window.
cd_/ {That's "cd" followed by a space followed by a forward leaning "/"}
ls_-l {That's "ls" followed by a space followed by the minus sign "-" followed by a lower case "l' }
You should see something like the following:

For the Applications folder as shown above, the "owner" is "root" and the "group" it belongs to is set as "staff".
Please note, I am NOT convinced that the group is set correctly, I can only say that it is working for me.
For future reference write down what is currently showing as "group" and "owner" on your system.
If you wish to change the owner of Applications, enter the following in the Terminal window:
sudo chown root Applications
You will be prompted for your password. Enter it and press return.
To verify that the change has been made, enter:
ls_-l
once again. Remember the "_" indicates a space.
To change the group, enter the following:
sudo chgrp staff Applications
You should not be prompted for your password again.
verify the change with the "ls_-l" command as before.
I hope you can follow these rambling instructions and that they work for you.
