Permissions are flags that set who can read/write/execute what. Since OS X, like nay unix, is a multiuser system, they are necessary. A pretty good introduction can be read here: http://www.onlamp.com/pub/a/bsd/2000/09/06/FreeBSD_Basics.html That being said, I've never got a satisfactory answer why the permissions go 'off' every so often on Mac OS X. It is not something that is supposed to just happen. > Usually a bit of an Apple fan, I was not impressed. Usually proudly > virus free, what can I say when Apple offers its own bugs? Everyone's got bugs, I haven't hit any big ones yet though. So did you manage to solve the original problem or not? > Any comments? My comment? OS 9 was really 'somethiing dfferent'. It was something compleely unlike anything else out there. While it was his big advantage, in the age of connectivity that has become also a big disadvantage. And now we are running just another flavor or UNIX, like it or not. Personally it suits me, but this is nothing like the good old OS 9. :)
