Succeeded to upgrade from Ventura to Sonoma, with some minor issue.

I managed to upgrade to Sonoma 14.2.1 today. Now the system is working fine.

My hardware is a Dell XPS desktop. Not sure the mother board model.

CPU: i5-11400 2.6G

GPU: AMD 6600XT

Opencore version: v 0.9.1

Other information is as the following:

Model Name: Mac Pro

Model Identifier: MacPro7,1

Processor Name: 6-Core Intel Core i5

Processor Speed: 2.6 GHz

Number of Processors: 1

Total Number of Cores: 6

L2 Cache (per Core): 512 KB

L3 Cache: 12 MB

Hyper-Threading Technology: Enabled

Memory: 16 GB

System Firmware Version: 1968.100.17.0.0

OS Loader Version: 580~1053

SMC Version (system): 1.74f4

​

There are two minor issues:

1. I cannot upgrade from system setting->upgrade directly. Always have error and be asked to check internet connection while my internet connection is always good. Then finally I have to get the new OS from App Store. The installation was no issue.
2. After login to the desktop I got warning: "Memory Modules Misconfigured. To improve performance, install memory in pairs and include at least four modules." I did installed memory in pairs. But only one pair. Do I need to add another pair? There was no such warning for Ventura.

Currently, only the above two issues found.
