Hello there!

I installed Catalina (10.15.4) using Unibeast. Everything work well (BT, Wifi, Airdrop, Airplay) except that system sometime got kernel panic randomly. I tried to figure things out but no clue why it happened. Computer work well on Windows 10 (dual boot) without any problem. Please help!

Mobo: Asrock Z390 Extreme4
CPU: i7 9700k (all core 4.8Ghz@1.35v cause less panic than all core 5.0Ghz@1.35v)
GPU: Sapphire RX580 8GB Pulse
RAM: XMP2@3000Mhz (Kingston HyperX Predator RGB 16GB 3200MHz DDR4 (8GBx2) HX432C16PB3AK2/16)

This might be a total shot in the dark, but could you quickly try switching your SMBIOS config to a iMac18,3 instead of iMac19,1?

You're currently using iMac19,1 which leads macOS to believe you have an i7 8700 ("non-overclockable" CPU, notice how the 'K' isn't present at the end of the CPU model name). I have the same CPU as yourself and I'm using iMac18,3 without any issue.

Take this as a grain of salt though, I have no authority over this topic, just a random idea

Are you seeing panic on both 4.8 and 5GHz?
