Let’s test then.

I have my three 10.13 systems set up with Xcode 10 and the last SDK it came with. Two of those are capped-out at 10.13 due to hardware, one is a VM.

Happy to throw anything you like at it, and see if we can break it.

You know I’m only involved in this issue to make all our lives easier, and specifically, so that 10.13 can get the current qt 5.15.2 on the buildbot so that everyone can enjoy it like I can.

Happy to help.
