I have used Intego Personal Backup X4 to clone my system (Tiger 10.4.8) to a new internal HD that I purchased today. I started working from the new HD and got a message from OS X that I was using Firefox for the first time. That got me to wondering whether I should expect any nasty surprises or complications in connection with using a cloned OS X system on a new HD... Anyone have an idea? Cheers, Brian
