I have accidentally added an entry to my defaults (/usr/bin/defaults) that is preventing me from installing apps via iTunes. How do I undo my change?
This is the command to read the offending entry:
/usr/bin/defaults read /Library/Preferences/com.apple.usbmuxd
Which gives the following result:
{
BlackList = (
"com.apple.iTunes"
);
}
It was added by
/usr/bin/defaults write /Library/Preferences/com.apple.usbmuxd BlackList -array-add com.apple.iTunes
I thought this would remove it, but I can't figure it out.
/usr/bin/defaults delete /Library/Preferences/com.apple.usbmuxd BlackList com.apple.iTunes
This just returns the help for defaults
Here are a few more things I've tried and the results
/usr/bin/defaults delete /Library/Preferences/com.apple.usbmuxd BlackList
Domain (/Library/Preferences/com.apple.usbmuxd) not found.
/usr/bin/defaults delete /Library/Preferences/com.apple.usbmuxd com.apple.iTunes
Domain (/Library/Preferences/com.apple.usbmuxd) not found.
Not sure what the "Domain not found" error is. I tried sudo as well and saw the same error message. Is that not the domain I just added to with the initial write step?
I think this is the command in defaults I want to use:
delete <domain> <key> deletes key in domain

You can delete the BlackList array with
Apple doesn't provide an easy way to remove an array element. You can either set the BlackList array with
-array
with the item excluded, or edit the file manually using Xcode for example.
