Apple has a habit of adding new features to OS X Lion that aren’t even available in older versions.
If you’re on Lion, you can update to Lion today.
The company doesn’t make the update mandatory, though it does include instructions to do so.
Lion update is free to users who have the newer OS X Mavericks.
If that doesn’t work, you’ll need to wait until the next OS X version, which will arrive on October 24.
You can get your Mac to upgrade to Lion right now from the Apple Developer Center.
The update requires you to install a third-party application called Macupgrade.
Macupage is free for developers to use and includes a free trial, but the software isn’t available to users.
If Macupupage doesn’t appear to work, Apple says it will contact you.
Lion updates to OS 10.8 Yosemite are still rolling out to users, so it’s possible that they’ll be available to install tomorrow.
If you have Lion, check your Mac’s status by running the Macupdition app on the Finder.
If Lion updates work, Macup upgrade should take care of it.
