I've just bought an iMac with OSX Lion and noticed that be default the firewall is off.
I'm new to OSX (but not iPhones, iPads & iPods) and with a PC background I'm very nervous at not having a software firewall and anti-virus and anti-malware programmes running. I'm becoming "relaxed" on the latter two, but the OSX firewall still bothers me!
I've read a lot of threads on various support forums and there's mixed views, for and against, but can I ask here whether......
- I'm taking a real (as opposed to theoretical) risk if I leave the firewall off?
- there's a downside to having the firewall on - other than configuration?
- configuration of the firewall is problematical?
The iMac is hard wired to a netgear router via ethernet and I use the internet a lot.
Activate the built-in OS X firewall. For some reason, the default is off. There is no downside to activating the firewall. As an aside, your router probably has a firewall as well - but that is no problem.
anti-virus and anti-malware programmes running
There are NO viruses that affect a Mac running OS X - NONE. A/V software, at a minimum, wastes resources and frequently causes serious problems.
