1. Jul 03, 2017 Skype now tells me that 'We've signed you out because you're using an outdated version of Skype. Download the latest version' - which of course does not run on Snow Leopard. You still get directed to download the proper 6.15 version for Mac OS X 10.6.8 but it does not work!
2. OS X Lion: Skype 6.15.x.334 OS X Snow Leopard: Skype 6.15.x.334 OS X Leopard: Skype 6.3.x.604. Note that the links above will automatically detect your current operating system and serve the appropriate installer. Therefore, if you need to download Skype for Snow Leopard, for example, make sure you do it while using a Mac running Snow Leopard.
3. To install Snow Leopard for the first time, you must have a Mac with: An Intel processor An internal or external DVD drive, or DVD or CD Sharing At least 1 GB of RAM (additional RAM is recommended) A built-in display or a display connected to an Apple-supplied video card supported by your computer At least 5 GB of disk space available, or 7 GB.

Install the App

   and press enter/return key.
   If the screen prompts you to enter a password, please enter your Mac's user password to continue. When you type the password, it won't be displayed on screen, but the system would accept it. So just type your password and press ENTER/RETURN key. Then wait for the command to finish.
3. Run:
   brew cask install skype

Done! You can now use Skype.

The department of Information Technologies & Services (ITS) has now completed the compatibility testing for Snow Leopard and supported applications for Mac. We have certified Snow Leopard for most of the applications and is now fully supported by ITS.

Please be advised that ITS will not provide support for applications such as iLife and iTunes. ITS can guide users through basic setup and use of these applications as well as recommend other resources for a more in-depth guide or 'how-to.' In addition, users will need the operating system media (i.e. installation DVD) to install applications such as Quicktime version 7.

To purchase a license for Snow Leopard, please contact the ITS Computer Sales group at csg@med.cornell.edu.
