Apple has changed how it distributes OS X Mavericks since its initial release in October 2013. This note was written on May 2, 2014. This affects the instructions you'll find online for how to make a bootable OS X installer.

It used to be that when you downloaded OS X from the App Store, the entire 5GB installer was placed in /Applications/Install OS X Mavericks.app. Now, there is a simple shortcut program placed in /Applications/OS X Mavericks.app. The app file is immediately removed in the event of an error or a successful post-install launch. When the download succeeds, the app file is launched which brings up the traditional install wizard, but this time mounted to /Volumes/Install OS X Mavericks.

I actually discovered this because if you already have a volume mounted of the same name (which I did, because I was trying to update my existing USB installer), the App Store download promptly fails right after finishing its download.

So if you have an empty disk you'd like to use as an installer that'

This is a simple little note I wrote down when talking to another company owner on the topic of moving a fully distributed team (with some folks in the same city) to a mostly-distributed team with an HQ office in a single city. It's not necessarily useful as general advice beyond that

why thoughtful physical location matters

I often advise clients that are actively focused on improving their teams to either embrace a fully-distributed team or a fully-colocated one, and to avoid other permutations of organization. Patterns that I see a lot:

• small satellite offices off a large HQ
• a handful of remote folk off a large HQ
• n similarly-sized engineering offices
