Upgrading to macOS Sierra (nee OSX) for R users

A good fraction of R users use Apple computers. Apple machines historically have sat at a sweet spot of convenience, power, and utility:

  • Convenience: Apple machines are available at retail stores, come with purchasable support, and can run a lot of common commercial software.
  • Power: R packages such as parallel and Rcpp work better on top of a Posix environment.
  • Utility: OSX was good at interoperating with the Linux your big data systems are likely running on, and some R packages expect a native operating system supporting a Posix environment (which historically has not been a Microsoft Windows, strength despite claims to the contrary).

Frankly the trade-off is changing:

  • Apple is neglecting its computer hardware and operating system in favor of phones and watches. And (for claimed license prejudice reasons) the lauded OSX/macOS “Unix userland” is woefully out of date (try “bash --version” in an Apple Terminal; it is about 10 years out of date!).
  • Microsoft Windows Unix support is improving (Windows 10 bash is interesting, though R really can’t take advantage of that yet).
  • Linux hardware support is improving (though not fully there for laptops, modern trackpads, touch screens, or even some wireless networking).

Our current R platform remains Apple macOS. But our next purchase is likely a Linux laptop with the addition of a legal copy of Windows inside a virtual machine (for commercial software not available on Linux). It has been a while since Apple last “sparked joy” around here, and if Linux works out we may have a few Apple machines sitting on the curb with paper bags over their heads (Marie Kondo’s advice for humanely disposing of excess inanimate objects that “see”, such as unloved stuffed animals with eyes and laptops with cameras).

That being said: how does one update an existing Apple machine to macOS Sierra and then restore enough functionality to resume working? Please read on for my notes on the process. Continue reading Upgrading to macOS Sierra (nee OSX) for R users
