Catalina 10.15.4 with the supplemental update seems to be the trouble maker for most hackintoshes compared to the 10.15.3. The new Clover boot loader is quite buggy. The Haswell HD4400 and HD4600 have kernel panic reboot after sleep/wake when using AppleAlc.kext (1.4.8) to patch IDT 92HD91Bxx sounds with Lilu.kext 1.4.3. The only way to work around this is to add No-hda-gfx=AAAAAAAAAA= in the device property. This one will solve the reboot kp but it disables the HDMI digital sound.

For Haswell HD4400, if we patched the kernel it works with no KP reboot and HDMI works perfectly.
