Filevault

well, i have a 12" 1ghz pb. It slow down boot time noticible, but the running programs want that big a deal unless it was hard drive intensive task. if your whole home directory is important to you, and you fear someone someone taking your hard drive or other users gaining access to your files via admin account then filevalut is a good thing. the way i solved my problem of traveling, and fearing laptop theft is i use you an external hard drive for backup with all sensitive files i create and encrypted dmg. so if anyone takes my laptop most of my files are ok. if you are worried about weather filevault function well, it does. i have had no problems.

 

I used it from last November up to just a couple weeks ago. My iBook was my work computer and had some confidential stuff on it. The computer ran as well with it as without it. The only problem I had was trying to import dv into iMovie--it just wouldn't work. When I tried it on a different account it was fine. If I had saved the movie outside of my home folder it probably would have worked as well. I think it couldn't keep up encrypting that huge flow of video. Apart from that it was perfect.
