Yosemite Beta program

[Paddy]

If you're interested in/curious about the next iteration of OS X, you can sign up for the public beta program. First one million users...

https://appleseed.apple.com/sp/betaprogram/ (BTW - despite what the Ars Technica article below says, the public beta isn't available for download just yet. Developers who've paid to be in Apple's developer program can download it now)

And how to install it on a test partition: http://arstechnica.com/apple/2014/06/how-t...eta/?comments=1

I'll probably put it on an external USB 3.0 drive...

And a handy list of supported hardware: <Will your Mac run OS X 10.10 Yosemite?>
Basically, if you can run Mavericks, you can run Yosemite.
The list is composed of the motherboard ID and the model. The motherboard ID is easily obtained by pasting in the follow line into Terminal:

CODE

ioreg -l | grep "board-id" | awk -F\" '{print $4}'

You can then look at the list at the linked page. If you'd rather not use Terminal, simply option-click the Apple menu and "System Information" will pop up and you should see "Model Identifier:" as the first item with "Hardware" selected (default).

Note that the list may not be complete since there is no listing for certain MacPro models (5,1)!
