Just want to share. I have been using Mac for myself and family (kids, teens and my wife) since 2009. Each of them has their own user. We have iMac and few MacBooks. I run Windows in Parallel Desktop - but only for some games and some windows-specific app. I didn’t use AV at all and not single one since then I found virus in Mac. I am careful when using admin user only (I am the only one who can use admin user), only allow access whenever I know exactly the details.
I can understand if people came from Windows world. My office laptop (Windows) also use AV (plus disk encryption) which keeps cpu and disk busy almost all the time.
I think AV in Mac is mainly for better comfort to people who recently came from Windows.
I also came from Microsoft (before that UNIX-6). My wife and I have 2 macs that are almost copies.
We have accounts on both machines. For safety we are in the same group and all directories
in our areas are rwxrwx---. That is quite safe.
The main difference between MSWindows and MacOS is that the first was based on DSDOS (=MSDOS)
and then NT (=VaxVms by DEC) while MacOS is based on UNIX.
In UNIX any file, process, pipe or connection has a user (owner). MSWindows HAS NO USERS, only access lists.
That makes MSWindows vulnerable. Besides, I have the feeling that APPLE cares a bit more about security.
The USER notion is a patent by AT&T and 'sits' in all UNIX variants, like LINUX, ULTRIX, BSD-UNIX, MacOS etc.
;JOOP!
