Opera has released a Mac version of Opera 10.50, whose Windows version impressed me when it came out a couple of weeks ago. Like that version, it uses Opera’s new JavaScript engine, which Opera says is eight times faster than its predecessor.
How does it perform? Well, Seth Weintraub of Computerworld and 9 to 5 Mac used the SunSpider test to put it through its paces, and found that it beat Safari and Chrome, the fastest OS X browsers in terms of JavaScript.
Zippy JavaScript performance doesn’t automatically translate into a browser that feels zippy. Judging from the time I’ve spent with Opera 10.50 today, though, it does indeed feel like an unusually fast browser in ways that earlier versions of Opera didn’t. (It also feels like a beta–it crashed on me while I was posting this articles–and so I’d suggest trying it as a complement to your main browser rather than a substitute.)
One of the things I like about the the Windows version is its Chromelike minimalist interface, which compresses all of Opera’s options into a single menu. Like Chrome, Opera isn’t so sleek on OS X–it’s got eight menus, plus the Apple menu and the Opera one. That’s at least in part because one of the most fundamental differences between the Windows and Mac interfaces is that OS X has a fixed menu bar at the top. If you start to remove menus from it, it doesn’t conserve space and leaves the bar looking a little naked.
Google Analytics tells me that 98.5 percent of Technologizer community members aren’t using Opera. On both OS X and Windows, I’m excited about 10.50’s potential to be the first version of Opera in a long while that tempts users of other browsers to switch allegiences.
