It’s not a review from famed OS X reviewer John Siracusa, but it has a similar flavor. This time it took two ArsTechnica reviewers, Andrew Cunningham and Lee Hutchinson to do the deed.
The subtle difference in El Capitan is that we’re actually seeing new features come to both iOS and OS X at the same time rather than existing on iOS first and then trickling down to the Mac later. Many of the biggest, most noticeable changes here are the same ones you saw in iOS 9 two weeks ago. The new Split Screen multitasking mode, tweaks to multitouch gestures, changes to services like Spotlight , and overhauled apps like Notes all fall into this category. Others, like System Integrity Protection, are merely iOS-inspired.
So, exciting? No, not really, not unless you’re a window management enthusiast who is excited to dance on Helvetica Neue’s grave. But it’s a free update. It has its occasional bugs and quirks (trying to enable Safari’s new status bar was enough to crash it a few times), but Apple is already working on the initial 10.11.1 bugfix release that will begin anew the process of smoothing out the problems that come with any new OS. Like El Capitan at large, that seems just fine to us.
I’ve been using El Capitan on an older iMac and it’s been rock solid. Haven’t installed all my App Store apps yet, though.
