I just got this MacBook Pro, Tiger, 10.4.8, Intel Core2 Duo 2.33 GHz, 2 GB, 667 MHz DDR2 SDRAM, from a third party person, but it's not allowing me to install programs without "Administrator Password". I don't know the Admin PW... (I'm glad it set to "Auto-Login"), and I know you can reset it using the OSX installation disc by holding the "C" key at Startup, but my Mac Book starts straight into OSX. I tried inserting the Disc in the DVD drive and tried using the "Startup Disk" in the "System Preferences", but the only options available are "Mac OS X, 10.4.8" and "Network Startup" I don't see the OSX Installation Disc. I did a little research on Apple website and found that maybe I need to disable "Open Firmware Password Protection" first before I could Reset the Administrator Password, but after reading a little it doesn't state how to "Disable" Open Firmware, but how to "Enable" it, it's disabled by Default. It gives an option on how to "Trouble Shoot" the Computer running Open Firmware, but only on "PowerPC-based" computer and not "Intel-based", because they don't use Open Firmware and my MacBook Pro is Intel-based!!! The other thing I noticed is a program called Deep Freeze Controller Version, by Faronics ver. 3.10.070.0134. Could this be the problem and if it is how do I get rid of it!!! It also asks for a Password which I do not know! Man I hope someone here can HELP as I always come here for all me questions!
