[thelist] Can current macs have multiple browser versions installed?

[Dave Merrill]

Web developer, on windows, considering getting one of the new inexpensive
macs, primarily for browser testing.

Is it possible to have multiple versions of common browsers installed at the
same time on a current mac? I probably mean IE, Mozilla/Firefox, Opera, and
Safari. If so, does it require hacks like on windows, or is it just a
normal, officially supported possibility?

Thanks,

Dave Merrill
