1533. Instal OS X Yosemite and save the installer

I support multiple Macs, and would like to install the latest operating system, OS X Yosemite, on all of them. I upgraded one last night, and my plan was to copy the installer to all the rest, but as soon as I installed the upgrade, the installer disappeared. Is there some way to download the upgrade only once and apply it to multiple computers (it is free, after all)?

As is often the case with these questions I make Doug ask the question but it actually happened to me. I do have multiple Mac's and was trying to install Yosemite on all of them and once I downloaded the installer and run it, it was gone.  

I then realized what I needed to do. You download the installer from the Mac App Store and befor you run the installer just make a copy of it. Then you can take this copy to the other Macs and run them.  

So you want to keep a copy before you run the install. There is no problem downloading it on each computer but it takes a lot of time. It is a large file.

This trck can save that effort. Run the copy before you install it. Then copy the copy to other computers. It will save you the downloading time.
