I have re-downloaded the Mac installer and re-created the usb but still the same. I will send you the clover files from USB shortly.
One more thing I noticed that wrong time in BIOS. So if I fixed it, it keeps the time but windows time gets wrong and if I sync in windows then BIOS time gets wrong. CMOS battery is toasted? any idea?

ok I did a CMOS reset hoping that it would fix BIOS incorrect time issue but it didn't. Interestingly during the assembling I tried to and able to boot pass those famous two lines ! All i had to do was remove the battery from the board and run the laptop on ACPI.

Since it was giving my ACPI errors so I assumed its due to my old patched DSDT so I removed all patched files and put SSDTDiscrete now I am logged in ok on High Sierra. Files are attached.

Things to note: DellSMBIOS = YES is giving ACPI error so I have set it NO.

Not sure how do I fix this battery stuff.

See post #2 of the Clover guide regarding registry edits required for Windows:

Your ACPI configuration is wrong. The OSID->XSID and _OSI->XOSI patches require SSDT-XOSI.aml. It is missing from ACPI/patched.

I think you're referring to DellSMBIOSPatch=true. Your ioreg shows no SMBIOS truncation, so that fix is not necessary in your case.

Read here for battery patching:

Seems like everything is working great. I believe your patch for Dell Inspiron 7xxx contains my battery patch as well (as I have noticed pre-bios problem).

patched DSDT is working but as soon as I connect my battery to board, the same famous two lines mentioned earlier in this thread.

No idea what you're referring to. You will need to provide details.

No such thing found as Preloader.efi as far as I could search, people are recommending OsxAptio2FixDrv and other variants such as OsxAptioFixDrv-2000 or something. None worked.
