Unfortunately alot of the folders in Lion are set to "wheel." So if you want to mod them you have to change the owner and the permissions, even if you're an admin user. To fix this, add your admin user to "wheel" group with the command below: sudo dscl . -append /Groups/wheel GroupMembership Then just change the permissions on your folders to where "wheel" members can write to them: sudo chmod 775 /MyFolder If you do the following it will also recursively (-R) affect all the folders inside that folder: sudo chmod -R 775 /MyFolder I did this for every single folder on my drive. I suppose it's less secure, but I also don't lock my silverware drawer at my house. Or my bathroom door. Or my sock drawer. Sure, someone could put a fer-de-lance in my tool closet or box jellyfish in my bathtub, but I'd really rather not unlock things every time. Join me, and live freely... and dangerously!
