MacOS virtual machine does not start (>20 minutes)

Recent change I did was try to get a nicer build matrix, by utilizing osx_image.
So I change from

language: cpp
matrix:
include:
 - os: osx
   osx_image: xcode10.2
 - os: linux
   osx_image: xcode10.1

to

matrix:
  include:
  - os: osx
    language: objective-c
    osx_image: 
    - xcode10.2
    - xcode10.1

Hey @KjellMorgenstern, sorry for the troubles!

The second config doesn’t work under matrix.include i.e. you cannot define a matrix under a matrix entry. It’s quite possible that this is what caused your macOS job to stall. Sorry for the inconvenience.

I’ll file a internal issue to fix this at the product level but I cannot give you an ETA at this time. In the meantime, I would suggest reverting back to your previous config.

Thank you for your understanding!
