Video Shows Differences Between Mavericks and Mountain Lion Multiple Monitor Support

During the WWDC Keynote presentation last week, Apple executive Craig Federighi showed off Mac OS X Mavericks. One of the new features is more substantial support for multiple monitors.

In Mountain Lion, there are issues with using full-screen apps on setups with multiple monitors. Putting an app into full-screen mode disables the rest of the monitors. In Mavericks, apps can be set to full screen on individual monitors and moved around as necessary.

However, as this video shows (via 9to5Mac), there are some changes in Mavericks that multiple monitor users may not like. For instance, application windows cannot be used across multiple monitors anymore -- windows can only be used on one monitor at a time. Also, spaces are only switched individually, which could affect the workflow of some users.


It appears that, in OS X Mavericks, users can switch between both the Mountain Lion multiple monitor setup and the new multiple monitor support in Mavericks as needed. As always, it's worth noting that this is a beta and things could change before the final version of OS X Mavericks is released in the Fall.

With just three days to go until the iPhone Duo is released, Apple is getting ready for the launch. Behind the scenes, the App Store now has screenshots of Apple's built-in apps running on the Duo. We've seen some apps in marketing materials, but images of the ones we haven't seen give us an idea of what it will be like using the iPhone Duo day to day. Many apps are shown in landscape...

Apple has temporarily removed Keynote, Pages, and Numbers from the App Store, just after releasing an update that added iPhone Duo support and a new Intelligent Assistant. It is not clear if the apps were removed intentionally, or if it is a bug. Apple has not said when the apps will be reinstated, but if it was in error, they should return soon.

RIP, MacBook Ultra

Monday October 19, 2026 9:37 am PDT by
Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

SO he doesn't like it in Mavericks because he can't see his pretty wallpaper on all 6 screens when he switches one of them? :rolleyes:

What a "nightmare"...




edit: Proposed fix that I think would solve this: Hold option key switches all screens

The only real issue is not being able to have an application spread across multiple monitors. That's the only issue for Apple to "fix".

One of the biggest complains people have had about the old version is this guys biggest complaint about the new version. People were complaining that they had to switch spaces on every screen when they just wanted to do it on one. The idea that you want all of your spaces to switch so that the giant background works correctly is ridiculous. It is working exactly how it should work.
Why is this so hard to get? The wallpaper is just a proxy for what he's talking about. You can't lay out a bunch of apps spanning his 6-monitor setup in one space, then a completely different set of apps spanning the array on another space, and then switch between those two spaces. That context is lost entirely with this arrangement.

It's not the wallpaper. It is not being able to switch all monitors at the same time. You can't cover an array of monitors with a single space, and switch between spaces like you can now.

Also, I don't think he's in any position to complain considering he doesn't even have his six monitors calibrated together.
