Hey everyone! I have a macbook here that doesn’t detect the internal display. It boots fine on High Sierra but not on catalina. I can get into recovery mode and preform features fine and I can display to an external monitor. I have cleared the PRAM and the SMC and I am not sure what to do next. The display connector looks intact and i have reseated all the connections. Any input would be nice! Macbook is A1707(2016 15” macbook pro) Thanks in advance!
I would create a USB-C bootable OS Installer drive with Mojave. Get to it first, then go for Catalina following the same process. Get the OS files from here: How to get old versions of macOSFollow this guide to create a bootable OS installer: How to create a bootable macOS Mojave installer drive
