Capitalising on the growing market share of the new Intel-powered Macs, if not the expected inevitability of a Mac OS X virus turning up ‘in the wild’ (not just as a proof-of-concept exercise), Symantec is ramping up its presence in the Apple world. New versions of its current Personal Firewall 3.0 and Internet Security 3.0 suite - both of which are currently PowerPC utilities forced to run under Rosetta on current-gen Intel Macs - are being rewritten as Universal binaries and will hit the streets alongside MacOS X 10.5 Leopard early next year.
