Good Day, I have an old iMac 2002 that I believe has Tiger on it (its the last OS before the one that needed intel chips to be installed). Any way I do not use it any more but I keep it around for old time sakes, it has a lot of sentimental value. Any way, I want to encrypt the HDD just incase and I am not sure which FileVault it has. It has a major flaw, the computer can dual boot into OS 9 and through OS 9 I can open files from the OS X Tiger partition (Even though the Tiger partition needs a password to log in). Can any one advise me on how to secure the data on that HDD? It would be great if I can encrypt both OS X and OS 9 partitions.
