I've used macs on and off since 1992, i've only ever used macs for surfing the net or using a word editor. But i have never installed software on a mac, i'm possibly getting one in about 2 months. Question is: How easy is it to install software on the mac. Example, lets say i have just downloaded mozilla, does it have an installer or something or is it command line stuff like on linux? I have no trouble using the command line, i just want to know what to expect.
