A new tab can be added to a Finder window that already has tabs by dragging a folder's proxy icon to the plus sign that appears in the tabbed window.
You probably know you can drag the proxy icon of a Mavericks Finder window to another Finder window's tab to move or copy it to the tab's folder. You can add the folder as a tab to a Finder window that already has tabs if you drag its proxy icon to the plus (+) icon next to the right-most tab of the tabbed window.
As you probably know the brandnew iOS devices like the iPad Air enable you to download the iWork and iLife apps for free. What I didnít know is that once you downloaded them to your new device, they will also be available for free on your older devices.
In my case I bought an iPad Air and also got the apps for free on my older iPhone 5. It makes kinda sense, since the download is tied to your Apple ID, but I still didnít think about that until I noticed them downloading on my iPhone. In my case Automatic Downlods were enabled. So if you have this unchecked you just need to download the apps manually. The will show the Cloud icon instead of a price.
No great hint, but maybe someone else didnít think about that, too.
When you're playing music in the Music app in iOS 7, there's a thin red playhead that you can drag to adjust the song's playback position. Tap and drag it around for what Apple calls "Hi-Speed Scrubbing." (Why it's not "high," I can't say. Maybe the programmers were hi.)
Here's the hint: You can adjust the speed at which you're scrubbing through the song, if you need finer-grained control: Tap and hold on the red line, and then drag your finger upwards.
As you drag up the screen, you'll note that there three other gradations of scrubbing speed: Half-Speed Scrubbing, Quarter-Speed Scrubbing, and finally Fine Scrubbing; that last mode lets you scrub through the song second by second.
Mavericks offers a lot less resolution options in the "Scaled" list than 10.8 or earlier did. This can be a particularly severe problem if the resolutions that it thinks your projector supports are not, in fact, supported by it at all, as was the case with my setup.The fix for showing the extended list of possible resolutions in Mavericks is undocumented, so far as I can find, but incredibly easy:
In the Displays preference pane, hold down the option key and click the "Scaled" radio button. This will toggle on and off additional resolutions for the device (including more scaled resolutions for the built-in display in MacBooks).
I'm not aware of any radio button ever having worked that way before, so it's easy to miss.
If your external display isn't showing an image at all because the OS got its "native" resolution wrong, you will of course have to click the "Gather Windows" button at the bottom of the preference pane to bring the window for the blanked-out display over to the working one, where you can then option-click it and select a good resolution.
If you use AppleScript applets to interact with UI elements, you may quickly find out that in Mavericks all seems to be broken. Every run results in System Preferences being opened to the pane that used to control UI Element Scripting, and finding the new controls in Security & Privacy -> Privacy -> Accessibility seems to have no effect.
This is a result of Mavericks splitting UI control authorization into per-app settings, combined with the Lion feature of remembering what windows an app had open when it was last closed.
Mavericks recognizes the app uniquely only as long as the app doesn't change.
WindowState information is stored in the app if you have permissions to modify it.
These two features end up caught in a fight.
The following Terminal command will prevent this by passing ownership of the applet to root and blocking you from editing it without authenticating.
Mavericks now considers each monitor a "Space". As a result, apps launch and have their menu bar in whichever monitor they were launched from. However, it's easy to assign apps to each monitor. Here's how:
First, you need to create an additional space in Mission Control. You can add it to either monitor.
Having done that, then when you right-click on an app in the Dock, you will see the option to assign the app to All Desktops, Desktop on Display 1, Desktop on Display 2.
If you are a heavy user of Spaces with multiple displays, then you have likely found that the new "full screen improvements" in Mavericks are a giant leap backwards. To get the old behavior back, just go to Mission Control in the System Preferences and uncheck the box labeled "Displays have separate Spaces."
