It ought to be switched on by default then this wouldn&#8217;t happen.<\/p>\n<p>Anyway, it is all actually quite straight forward. There are <a href=\"http:\/\/www.macworld.co.uk\/mac\/howto\/index.cfm?articleid=196&#038;pagtype=samecat\">guides available<\/a> to show you how to do it. The problem is that they are a bit too technical in language and also are not clear on how to decide what to put in the table of allowed programs. The answer is don&#8217;t put any in manually, let them ask you first and then decide if you want to allow it.<\/p>\n<p>The sort of programs which will ask and need it are IM\/VoIP (iChat, Adium, Skype) and Download\/Upload services (&micro;Torrent, iPlayer, CyberDuck). Your browser may also ask, it rather depends on what sites you go to. Some applications ask more than once but eventually they remember. The ones that don&#8217;t ask and shouldn&#8217;t need it are Mail\/RSS\/News (Thunderbird, iMail), Text (NeoOffice, TextWrangler, TextEdit, MS-Office) and (to my surprise) Virtual Machines (VMware Fusion, Crossover and probably Parallels). In any case, you ought to run a local firewall in virtual machines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Confession: Until last week, I had it switched off.
