visto che non vi erano grandi modifiche nel config, ho piazzato OC 0.5.5 beta, tutto OK, la cosa più interessante è il nuovo SSDT-PMC nei sample, che aprendolo recita questo:
/*
* Intel 300-series PMC support for macOS
*
* Starting from Z390 chipsets PMC (D31:F2) is only available through MMIO.
* Since there is no standard device for PMC in ACPI, Apple introduced its
* own naming "APP9876" to access this device from AppleIntelPCHPMC driver.
* To avoid confusion we disable this device for all other operating systems,
* as they normally use another non-standard device with "PNP0C02" HID and
* "PCHRESV" UID.
*
* On certain implementations, including APTIO V, PMC initialisation is
* required for NVRAM access. Otherwise it will freeze in SMM mode.
* The reason for this is rather unclear. Note, that PMC and SPI are
* located in separate memory regions and PCHRESV maps both, yet only
* PMC region is used by AppleIntelPCHPMC:
* 0xFE000000~0xFE00FFFF - PMC MBAR
* 0xFE010000~0xFE010FFF - SPI BAR0
* 0xFE020000~0xFE035FFF - SerialIo BAR in ACPI mode
*
* PMC device has nothing to do to LPC bus, but is added to its scope for
* faster initialisation. If we add it to PCI0, where it normally exists,
* it will start in the end of PCI configuration, which is too late for
* NVRAM support.

qui poi mi ci vorrebbe l'aiuto di uno esperto.. unica cosa elementare che capisco.. è che è di aiuto per quei poveracci 😄 con le Z390
