What Works:

• Sound (updated to use AppleALC audio kext)
• iMessage
• Continuity/Handoff

• Onboard Wifi ax card

Odd items:

• AAPL: [EB|#LOG:EXITBS:START] error on startup until leveraged a boot patch included in the config.plist

Other notes (mostly hardware-specific notes to self):

• 3200Mhz rated ram is unstable when clocked to 3333Mhz (3200 XMP works though)
• i7-10700 CPU clocked with power limits removed reaches 72C @ 75F ambient during R20 with score of 4826
• Clocking the CPU to 102.9Mhz yields slightly higher speed for CPU and ram (around 3300Mhz) and appears to also run stable
• RX590 works without any special setup and runs relatively cool at around 50-60C at idle
• CPU at idle runs around 30-40C @ 70-80F ambient
