Thank you very much for your reply. My apology for confusing the CPU PM file. I opened the file, with MaciASL, and saw "Intel(R) Core(TM) i7-3540M CPU @ 3.00GHz" as listed as "host processor" in the DeBug statements, and did not realize that was just a reflection of the host (i.e. E6320) where the ssdtPRGen was run. Thank you for correcting my mistake. I tried the install again on another E6220 unit (i5-2540m CPU, everything else identical), using the original EFI folder from the guide, and ended stuck at the exactly the same point. So, it appeared to point to a likely similar root cause. In this case, also a mismatched CPU (i5-2640m vs 2620m PM file). I will try two things next: 1) High Sierra Install Guide. 2) NullCPUPowerManagement. Thank you!

Reporting back: Tried your CPU PM file, SSDT-PM_i7-2640M.aml file, by renaming to SSDT-PM.aml and replaced the original SSDT-PM.aml in ACPI/patched folder. This time, it went a bit further (a couple of more message lines), then stuck. Noticed this CPU PM was for i7-3540m, isn't exact match for i7-2640m (3/3.7GHz vs 2.8/3.5 GHz, also Ivy-Bridge vs Sand-Bridge). I will looking into the NullCPUPowerManagement kext, as you suggested in High Sierra guide, to boot ups the system first. One question: I see no DSDT.aml in Majove Guide. Is this the intended SSDT only patch solution? Really appreciated your help! Thanks!

No, I haven't changed the CPU ssd. I was hoping it would at least boot, without KP. Based on your High Sierra Guide, that appears not to be the case. BIOS settings followed exactly your guide. I will try your provided CPU PM file (just noticed that!).

Trying to install Mojave to an E6220 (A14 BIOS, i7-2640m, 8GB, 500GB regular drive). Followed the Herve Guide. Created the USB installation stick (Mojave 10.14.6, 18G103, from Apple site), Clover/EFI (all directly from the guide's download link). Booted from the USB, toggled the "-verbose", launched the install. But the install process stuck at the following stage (see capture screen - Stalled-1.jpg): Waited for 20+ minutes. No progress. So, reboot the machine and tried again. It stuck at the exactly the same point. There were number of "ACPI" errors at the begining, before reaching to this point (see attached screen capture - Stalled-2.jpg). Haven't figured out how to capture the entire screen output to a debug log file yet. I will try to do that if it helps to identify the root cause. What could be the issue? Your help will be greatly appreciated! Additional detailed for this machine: E6220, A14 BIOS, i7-2640m CPU, 8GB RAM, 500GB drive. Wireless cards (Intel Ultimate-N 6300, and Broadband GPS 3G card).
