Figure out how to automate install on Mac/Darwin

[pdehaan]

Need to find out how we can auto-mount a DMG and silent install.

I assume doing uninstall for Darwin is as simple as deleting the folder with the *.app.

Ok i remember now.
Mount to /Volumes with this command:

Then,
$ cp -R /Volumes/xxxx.app
Then kick back with a book

SMASHING, RICKY!

Oddly, this initial attempt seems to work (naturally we prefer to avoid sudo if possible, since that'd be blocking):

$ hdiutil attach firefox-45.0a1.en-US.mac.dmg -mountpoint foo45
expected   CRC32 $740D6CD9
/dev/disk3              Apple_partition_scheme
/dev/disk3s1            Apple_partition_map
/dev/disk3s2            Apple_HFS                       /Users/pdehaan/Downloads/foo45

$ ls -las foo45

$ ./foo45/FirefoxNightly.app/Contents/MacOS/firefox --version
Mozilla Firefox 45.0a1

Although I think more investigation is needed, because if I unmount that device in Finder, it sort of disappears from my machine. So maybe your three-step process of attaching+copying+detaching is better.

Yay!! Thanks man
Anxious to get back to this.

Closing. I'm happy-ish with our solution in 16aff3b.
I'll do a future PR to move the hdiutil stuff into a separate module to mask some of the horror.
