Is there Easislides available for Mac? I need to install it on that OS.
You can't install it on Mac OS X because it's not released for this operating system. Based on the download on the official website, you can install on both 32 and 64bit versions of Windows Vista, 7, and Windows 8.

Additionally, you can install the application through an emulator like WineBottler.
WineBottler makes it easy to install Windows apps on Mac without an actual operating system.
