This is a report without much technical information. I figured I'd post anyway as a placeholder and as a place for others to note if they've experienced the same thing.
Basically, when I frequently upload code to a Teensy 4, eventually, my MacBook Air grey screens (the system experiences a hard crash). This has happened often enough and just with this device that I thought it was worth a post. I haven't seen crashing at a specific point, just that when I do a bunch of upload/test/monitor cycles, this happens eventually somewhere during one of these cycles. I don't know if it's during upload or during executing/monitoring.
I'd like to emphasize that I'm not saying that the Teensy 4 or its stack is doing anything wrong, just that my Mac is experiencing hard crashes and am wondering if others have seen this too.
My system:
MacBook Air (model 6,2 from mid-2014), 8GB RAM, OSX 10.14.16 with all the latest updates.
Some possible explanations:
I haven't seen crashing like this since Bluetooth was starting to become normalized in OSX, more than 10 years ago. I'm sorry I'm not able to pin down this elusive crash. The only log I have is the window that pops up when the machine restarts that sends the report to Apple.

Some possible explanations:
- Bad USB ports on my laptop.
- Something about OSX's handling of USB in certain cases is buggy.
- Teensy 4's USB stack does something wrong or out-of-spec, or even some timing is a little off or has a race condition.
- Teensy 4 is using some feature that OSX can't handle well.
- Apple's USB and USB-related drivers do something wrong.
- It's something specific to my machine setup.
