If I plan to install a 10.14.6 patched by dosdude, are there any known issue, generally speaking, especially if I run it with the gigabyte HD 7950 and the Sonnet NVMe system? and what kind of post-install stuff you suggest me to install ?
Thanks

What you would gain with a hacked install? Your configuration supports Mojave natively.

Hello tsialex,

What you would gain with a hacked install? Your configuration supports Mojave natively.

Because this would be true without the kernel panics and the reboots, which happen anytime, not just sometime, when I start the mac with a dual monitor configuration.
I've already tried all the mojave installers, from the .1 to the .6 and the problem is still there.
I've flashed in the card all the 14 bios from the gigabyte site, tried netkas hack on some of them, but the problem remains.
I've tried the dosdude patch installing all the post-install stuff, except "legacy drivers" and still it's there.
I've finally post-installed even the legacy drivers, and in the end now I can boot and reboot with dual monitor and no kernel panics, although in system report the metal compatibility and the family specifications have disappeared (somehow it's just like it has always behaved in High Sierra).
So at this point I've decided I can work with it as it is, with the dosdude patch, as I don't care of the metal thing.
I've run a Heaven Benchmark and I tell you I don't need flying dragons and rotating castles, I just need a dual monitor configuration to run the scrolling of the audio files of the sequencer, see the mixer in the other monitor, and pray I don't have glitches when inserting an audio plug-in in a slot or when editing a wave.
That's why I ask you if there are known issue of this kind or similar in running the dosdude patch in place of the official OS, even if I presumably have the supported hardware. Which, for my experience, is just an half true statement although what you say is generally irrefutably true. This means the card is probably not good, or the Apple adapters, or the vga cables or the monitors.. I've tried out 6 different vga cables, tried all combinations using 3 different monitors. I don't know really, but I'm tired to boot the mac 700 times in a day just to try solutions that just won't do the job.

If this was happening to me, I'd replace the GPU. Why trying to live with a defective one?

Because I'm broken ?
: )

Naah apart jokes, I'm the kind of guy who try to go deeply inside the issue in order to solve it...there must be a way !
For instance, I even try firstly to remove completely then to replace the "AMDRadeonX4000.kext" with the one from HS (I tried to cheat the diagnostic report, by modifying the kext which I believed was the cause of the issue).
Wanna know what happened ? at next reboot, no more kernel panics, but the metal plus family specs were gone, and a strange brownish/yellowish aspect of the whole Mojave graphics appeared. What was called "blue" in the color's tab, was displayed as brown/yellow.
