Installing Blender on iMac OS-10 I installed Blender on my laptop (Win-10) and things went well.  However, my desk top is an iMac (OS-10 Yosemite).  I have no understanding of the iMac -- at all.  I read the answer to a previous question and read the guide to install on OSx.  I am totally lost.  Can you help me further?
I am familiar with GNU since I have used the GNAT developer.
You just copy/place the Blender folder in your Applications folder. To start Blender open the folder inside Applications, double-click on Blender icon and that's it. You can also drag the Blender icon and put it in your Dock for easy access.
