Hello, My HP Z 440 running Olarila Sonoma 14.3 is working perfectly except when I would like to reboot (or poweroff) that after restart (or power on) I get message like this: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ POST Error The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your BIOS Setup options to see if they changed. CMOS Reset(502) ENTER-Reboot the System For more information, please visit: www.hp.com\go\techcenter\startup ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ My BIOS is in the latest version and battery is OK (tried to change it to new one). Also after a boot a keyboard is not working unless boot is completed and logon screen appears. When I'm using Windows on the same PC the problem does not exist. Is there anything I can do with it? Thanks in advance for any answers.

Thank you so much, I followed for this tutorial, had installed latest AppleALC and Lilu kext's tried all three layouts for ALC221 (11,15 and 88) as stated in your tutorial and in every case I had no sound device. Should I change something else? Or how to debug this?
