No problem here - but took 24-25 minutes (on a passively cooled system). Maybe I need a new Hackintosh ;O)

Hardware problem confirmed: nano PSU 150 (I am using a passive case) causes/has problems. With big desktop PSU no problems. Cheers, Rudolf

Could this be a Meltdown or Spectre related problem? I installed Windoze on a different disk and Luxmark also causes a reboot there (when operating on both processor and GPU). @toleda : have you tried that with your i5-5675c? Thanks! Rudolf

It seems to be connected to heavy load on CPU and GPU: iTunes with Visualizer on caused a panic/reboot after few 10s of minutes. No reboots without load... (so far)

It does not make a difference whether its there or not... Have you got any ideas? Should I restore 10.14.2 and see if the problem was there as well? Running GeekBench is no problem (temperature does not rise much there, too). What else could I try to challenge IGPU & processor - to see whether...

possibly connected: I added an SSDT for my processor at some point...

Just did not get any verbose output - like I do when it is panicking on boot with -v... I have now been looking at the temperature - when running normally, I can start LuxMark a few times in a row - temperature going up after each run (IGPU only). Starts around 65°C, ends around 75°C. I then...

Thanks Toleda, 3.1 should be the latest, right? Do you confirm, or should I? No KP - it just spontaneously reboots... No CrashReports...

With 10.14.3 I can go back to 16,2 without panics when booting etc. New problem: my system reboots spontaneously when running Luxmark. Happened twice with 14,2 system definition and once with 16,2. It once did get through the ball, yielding a good score. Any ideas what could be causing the...

After installing 10.14.3 my system spontaneously rebooted twice when running Luxmark. Just for the heck of it, I tried using 16,2 again - and now it works. No boot loop, no kernel panic. Apple must have changes something in that respect. Unfortunately, Luxmark once also caused a spontaneous...

Similar issue here - but not as severe. Screen goes dark every half hour or so for a second or two and comes back. Not a screen saver - during work... Cheers, Rudolf

I still have this problem. My system is running nicely with 14,2 system definition. I have added audio by hand, configured USB by hand, etc. got graphics acceleration to work again with whatevergreen - but as soon as I go back to 16,2 system definition, I get that panic when booting. I can live...

Thanks for the guide, just wanted to let you know it worked out for me with my Broadwell IGPU HD 6200 of my i5-5675c. I did have to rename GFX0 -> IGPU. Also went through screwing up the config.plist with Clover Configurator once. For me it was not perfectly clear in the beginning, where...

Thanks Toleda, I just tried Whatevergreen and am back to accelerated graphics. Question about your i5-5675C: are you using just internal graphics? What system definition are you using? Thanks and best wishes! Rudolf

Hi Toleda, I used the trial version for now... don't understand, my processor is a series 5: i5675c with Iris pro 6200. iMac 15 had a series 4 processor. As far as I can see (after quickly looking over the linked page), it also states iMac 16 there for my Broadwell processor? According to my...

Thanks Toleda, I specified my GeekBench OpenCL score. With Lexmark I don't even get 1000 (just GPU) and less than 2500 together with my i5. I think that was better with Sierra. I did not notice at first, but when even iTunes visualisations were slow and were not fluent any more, I got...

I now got my system up and running - Bluetooth needed a little help. I had to change from 16.2 to 14.2 system definition, and my hack is recognised anyways - however, even though it looks good in system information, I do not seem to have acceleration. Are there any pointers to guides? My...

... Wow ... That's right! And you know what - now that I am using the right kext - it works ;o) Thanks a lot...! You are fantastic ;o)
