I'm trying to re add apple hardware test, and I've downloaded the correct file. and i need to copy the system/library/coreservices/.diagnostics to the same coresuervices folder on my mac.
however when i try to it won't let me drag and drop, or copy and paste, it tells me i haven't the right permissions.
when i try to change the permissions it lists
system read and write
wheel read only
everyone read only
when i try to change everyone, or add my admin account i get 'the operation can't be completed because you don't have the necessary permission'
