He could ask a friend (like you :-) ) who has internet access and go to :
Of course he will need to enter his Logic Studio serial number and other infos.
ok ive registered my friends Logic studio via the link u sent. Does that mean the registration page will not show anymore ? i read that the registration page comes up every 5 logic launches or something like that, is there another step he has to do to stop that?
The registration will still show because your friend's Mac is not connected to the internet. If you don't like this reminder window, open the Terminal (in Applications > Utilities ) and paste this command at the prompt :
defaults write /Library/Preferences/com.apple.RegLogicStudio AECoreTechRegister YES
