Gigabyte Z390 M Gaming build with working NVRAM

Try disabling "Reopen windows when logging back in" and see if your shutdowns go a bit quicker.

Hi I tried this but it is still showing the background wallpaper for sometime and then powers off, the same happens for restart as well. Usually in my earlier Hackintosh on Mojave I used get an animated sun like icon before it shuts down. not sure if that is the case for catalina.

Thanks

I don't recall seeing an animated sun on shutdown... But I really don't shutdown often either...

I think slow shutdown is more of a macOS issue and not a hackintosh issue. Please try some of the fixes in the link below.
 
Please try booting in verbose mode and video the installation process just before the reboot. I need to see the kernel panic that is causing the reboot.

Usually, it's GPU related when it reboots at approximately that phase... Please try with IGPU disabled in BIOS.

Booting in verbose mode requires me to boot into the Clover menu and then add -x to the boot args, correct?

iGPU in my BIOS...is that 'Internal Graphics' setting under Advanced > Settings > IO Ports? The description below references IGFX which is the closest approximation I can find to iGPU in my BIOS.

Err, a quick Google check corrected me (I think), in that I need to add the -v flag to the <key>Arguments</key> string list in the config.plist?

At the Clover boot menu, you can press the space bar and select to boot in verbose mode.
 
OK Day 3. I installed Logic 10.5.1 yesterday, which is what motivates my Hackintosh builds, The "playhead" was not drawing itself which was very bizarre. I've been doing a lot of reading mostly on TonyMac but also on Logic fora and I concluded it was a metal compatibility issue. I tried to test the GPU using MetalTest.app, Geekbench and Cinebench but niether of the 3 would allow it which corroborated my feelings. There have also been some subtle graphics glitches.

I reseached my cheap GT730 card purchase throughly. Using theTechPowerUp GPU database (https://www.techpowerup.com/gpu-specs) the card i found on ebay BEFORE buying it clearly came up as "Keplar" chip based GT730 thus making it Catalina and metal compatible. I suspect their database is fallible and that my card is NOT Keplar based as there were puzzling anomalies on further researching the card this afternoon (I'm in the UK).

I decided to attempt to use one of PastryChef's EFIs from post #1360 built for using IGPU as clearly PastryChef's EFIs are very solid and should be working but somehow never have on my system. I changed my BIOS to IGFX, swapped my DVI cable to the inbuilt GPU and the EFI failed again. I booted a few more times in verbose mode to see if I could spot anything (not that I know what any of it means) but there was a "panic".

I decided to physically remove the card and the EFI booted smoothly, the Logic playhead was visible and I could test the GPU using Geekbench.

PastryChef had a feeling all along my card was duff and he was right DESPITE the wealth of information suggesting the card was compatible. I had a diffcult first few hours with the install which I suspect was all to do with the card. Were it not for that I think the install may have been seamless from start to finish.

The system has been running well despite the graphics issues and now they're gone.

I'll install my dual boot windows system at some point.

Many thanks
Tony

Which GT 730 do you have? There are several different versions of it... One is Fermi based.

Performance-wise, the UHD 630 will probably perform pretty close to the GT 730. The only downside is that the motherboard only has HDMI 1.2 and DVI-D out ports. Personally, I'd try to use DVI-D rather than HDMI if possible.

I would suggest it is the Fermi chip and not the Keplar chip - hence the issues. HD 630 is apparently better (https://gpu.userbenchmark.com/Compa...5-i7-vs-Nvidia-GeForce-GT-730/m356797vsm12582)!

I'm using the DVI-D port.

Thanks Chef!
Ps. I'm up to page 66 of this thread picking things up as I read.
