Yes, I have already checked this and the 'Sonoma Laptop support' Guide. Most of the posts in Sonoma laptop support are about issues or other discussions. A very few are about success. So I am supposed to check who succeeded with their build and follow along?
I have observed that there are lots of well-written guides for desktops (in the Golden builds or user builds section). I had followed a guide by trs96 for hp 8300 in past. Do we have something similar for laptops?
I have found this one only for Sonoma:
DISCLAIMER This laptop is not my primary computer so I took the risk of upgrading to Sonoma. I was okay with starting from scratch if it did not work. If you would like to proceed with upgrading, make sure you back up all your data and have a working macOS Ventura USB installer media available...

Any other hints?
