0.7.0 live USB fails to boot on MacBook Pro 11,1 (mid-2014 13" Retina screen)

**Describe the bug**
Attempting to run helloSystem 0.7.0 via Live USB on a mid-2014 MacBook Pro 11,1, the FreeBSD kernel starts the boot process, then crashes before helloSystem is loaded. This triggers a reboot. (The same USB boots normally to helloSystem in my Thinkpad w530, so I know its not an issue with the installation media.)

**To Reproduce**
Steps to reproduce the behavior:
1. Create a helloSystem 0.7.0 live USB stick.
2. Boot a MacBook Pro 11,1 (mid-2014 13" retina screen)
3. FreeBSD kernel starts boot process, then crashes and system reboots into macOS X.
4. See error

**Expected behavior**
I should be able to boot to helloSystem and then verify that the MacBook Pro's hardware will work with helloSystem.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Version (please complete the following information):**
- Live ISO or installed system to disk: Live 0.7.0
- FreeBSD version (System --> About this Computer): n/a
- helloSystem build (`cat /.url`): 0.7.0 release
- Running in a virtual machine: no

**Computer (please complete the following information):**
- Device: MacBook Pro 11,1 (mid-2014 13" Retina screen, i5 Intel processor, 16 GB RAM.

**Additional context**
Any advice how I can capture a log of the kernel crash to share it here for troubleshooting would be appreciated. I see a ton of output when I boot the live USB using "boot -v" but the video I took doesn't show enough detail to read it. For what its worth, I've uploaded the video here: https://mamot.fr/system/media_attachments/files/109/258/281/675/400/183/original/71cf8fc1dba6db73.mp4
