It's pretty presumptuous to assume you know what John Gruber does with his Mac. I suspect he might sometimes open an app other than BBEdit.
And I know mxcl works for Apple, but not on homebrew. The lead maintainer works, I think, at GitHub?
Edit: in fact, from the commit logs, mxcl doesn't seem to have been much involved in homebrew in years. It's a poor show for github to seemingly be more interested in helping make macs work well for developers rather than Apple, imo...
I'm not sure Apple would ever give him marching orders on an open source project that he wasn't "much involved in...in years", including years before his Apple employment.
And I need a new workstation for more intensive workloads than any MacBook Pro can handle, and have been holding off on what to get.
Until this announcement, I assumed, based on the neglect of the mac pro and mac os, that Apple was basically going to just run out the mac business. I had started trying to figure out what my next computer was going to be after a decade of macs, and was pretty bummed by the options.
Hopefully they're serious about this.
If they're looking for other things they could do, may I suggest doubling down on fixing mac os quality issues. And hey, maybe even hire the homebrew folks.
