How to activate the airplay on the old Mac

How to activate the old airplay on the Mac? Airplay is a technology invented by Apple that allows you to send display signals from your Mac to your second-generation or third-generation Apple TV over the cloud. You can also transfer videos and music from itunes, and more and more recent Macs have allowed you to extend or copy your Mac desktop to your TV by airplay mirroring.

Mirroring is really useful, it allows you to get rid of cables and make it easy to do personal presentations, slide shows or watch movies on a big screen, or a high-definition TV as a second computer monitor, but because of the hardware requirements of apple, the strict requirements mirroring function only supports the new Mac, So the old Mac can't output video files through airplay.

Note: Airparrot can be compatible with any system running OS X10.6.8 or updates and based on the Core 2 Duo or higher processor Mac. If your machine is out of date or later than listed below, you can use OS X's own airplay function: the IMac (2011), Mac Mini (2011), MacBook Air (2011), MacBook Pro (early 2011), MAC Pro (late 2013).

The display section of the Drop-down menu displays information about the connection screen and the built-in screen. If you choose to extend your desktop, your TV will be part of the Mac desktop and we have a higher resolution screen, as shown above. You need to move the cursor from the Mac to the TV to select the extended desktop.

3. Extend only one app

Using the specified application (Specific app) option, you can send an application window to Apple TV, and you can operate on the Mac desktop as usual. This is a great feature when you need to continue working on a Mac and need to do a personal presentation or PowerPoint presentation.

If it is slow to transfer to a third-generation Apple TV with a 1080p quality, there is a choice in the Preferences menu to force output at 720p resolution. If the display aspect ratio does not fit the screen when mirroring, you can also stretch the application window to fill the Apple TV screen.
