Hey there - thanks for this awesome resource. I've got a nearly identical system (i7-9700K and Aorus Ultra Z390) and managed to get the system upgraded to the iMac19,1 system definition similar to what you did here.
After the switch, and presumably new serial number, did you have issues with Messages and Facetime? iCloud signs in fine, but Messages and Facetime say an error happened during authentication. I've done the sign out of iCloud, delete cache files, change time zone dance, and same result. I'm worried at this point I'm going to need to do a fresh install with another new serial number to get everything back to 100% working again. 😢
