Boaz - hi ! Applejack is a small, free utility which is available from: http://applejack.sourceforge.net/ You install the program, then use it to take care of your hard disk. You start the computer in single-user start up mode (start up holding down Apple-S), type "Applejack auto restart" (other options are possible) and it performs disk and permission repair routines at the Unix level, plus cleans up caches, virtual memory files, etc. I use it (i) as a regular maintenance program, perhaps once a week (ii) if there is any problem with the start-up; typically if you unexpectedly shut down OS X, or something dramatic like that, which kind of "upsets" OS X. The advantage of Applejack over many other similar utilities is that it operates below the OS X level. There is clearly some basic incompatibility of AppleJack with Leopard, which I hope is easily fixed..... By the way, you can always check on Version Tracker (http://www.versiontracker.com/macosx/ ) to find the source of any program or utility or application or software, original or update. I check it (almost) everyday for software updates of 3rd party software. regards, Trevor
