Greetings, NSHipsters!

As we prepare to increment our NSDateComponents -year by 1, it's time once again for NSHipster end-of-the-year Reader Submissions! Last year, we got some mind-blowing tips and tricks. With the release of iOS 7 & Mavericks, and a year's worth of new developments in the Objective-C ecosystem, there should be a ton of new stuff to write up for this year.

Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Here are a few examples of the kind of things I'd like to see:

  • Using NSStringFromSelector(@selector()) as a safer way to do KVC / KVO / NSCoding.
  • Panic's [rather surprising discovery about the internals of the Lightning Digital AV Adapter](http://www.panic.com/blog/the-lightning-di

macOS FileVault encryption and OpenBSD encrypted softraid on a Macbook Air/Pro

Update (2019-05-06): The Broadcom wireless card in the MacBook Pro works and can be crammed into the Air.

Update (2015-12-04): This document used to be very lengthy as there were many manual steps required to get OpenBSD and Mac OS X working together through Boot Camp Assistant (BCA), which created a hybrid MBR and enabled a legacy BIOS emulation mode which older versions of Windows (and OpenBSD) required. Newer Macbooks stopped supporting older versions of Windows through BCA and now only support Windows 10 since it uses GPT and UEFI. However, now that newer versions of OpenBSD support GPT and UEFI, Boot Camp Assistant is no longer needed at all to boot OpenBSD.

OpenBSD works pretty well on at least the Mid-2011 Macbook Air (A1370, SandyBridge) and Mid-2013 Macbook Air (Haswell). The new KMS code in 5.4 brings up the MBA's eDP display in 1366x768 with backlight
