Is it possible to disable safe-boot (shift key during boot)? I have just discovered that safe boot overides the firewall I have installed (Norton) and gives access to internetservices I want to block out. It is very important for me that nobody can access the web without going through Norton .

IMac, Mac OS X (10.4.6)

    Yes by not holding the shift key during boot or startup.

    Starting up in Safe Mode is for troubleshooting purposes only.

    Thankyou - I guess my question wasn`t clear enough; does this mean that there is no way what so ever (except to use a wireless keyboard) to take away the possibility to safe boot in os x? I know this sounds weird, but a really need to get rid of this option.

    You're welcome.

    Maybe your question wasn't clear enough but I still don't understand.

    I've been using OS X since first introduced by Apple and I've never accidentally booted into Safe Mode. This requires holding the Shift key after the startup chime only during the entire startup process which takes longer than a normal startup.

    I'm not aware of a way to take away the option and the possibility but booting into Safe Mode is not something that is likely to occur by accident or unintentionally.

    Sven,

    I gather you're concerned that someone else using the Mac may intentionally restart it in Safe Mode to bypass your security settings? As Allan has noted, there don't seem to be any ready methods to disable Safe Boot on Macs (not unless you want to try rewriting the launchd daemon, or change Norton Firewall's driver KEXT Info.plist files to change the OSBundleRequired values).

    However, you can implement the Open Firmware Password to restrict others from restarting the computer (in either Safe or normal boot modes).

    If you know the particular firewall settings that Norton implements that you can't normally access using the built-in OS X Firewall, look over the Firewall section (4.10) of Corsaire: Securing Mac OS X.

    Thankyou, both of you! Sorry that I didn`t manage to state my question clearly. I guess my way out will be to hide away the keyboard and replace it with a cordless one. Thanks for the firewall link.
