So, this little tutorial is meant to help people fix a new issue with Mojave: opening jpg files (looks like it happens with larger files, not so much with smaller ones) using Quick Look (on spacebar key pressed) or Preview app using the dedicated GPUs.
The issue is that, when trying to open jpg files (for some reason, it doesn't occur with pngs), the pop-up window would remain in an endless loop. And from that point forward, any other app trying to open the same file, will either become unresponsive (in the case of the Preview app) or just stay in endless loop (in case of Quick Look)
As a workaround, in case the tutorial below doesn't work for you, you can use Grab (built-in app in MacOS) to open said files.
This issues DOES NOT occur using the iGPU. So...if you're comfortable using the iGPU, just switch to that and you should be good to go. You don't need this tutorial.
This tutorial is based on @Cyberdevs' research and testing on this topic (especially useful if you're using an RX series AMD video card), and my own very limited time testing this on my rig. I just thought it would be useful to create a new thread for it so that people can discuss this particular issue here.
The main thing we need to do is actually very simple: we need to enable the iGPU (integrated GPU) by default, in BIOS, while actually being connected to the dedicated GPU.
With that being said, I'll just move on to the actual tutorial.
For ATI (curtesy of @Cyberdevs' post here).
The discreet GPU should be set as primary in BIOS and your displays should be connected to your discreet GPU
The iGD/iGPU/iGFX must be enabled in BIOS/UEFI as the secondary GPU.
I removed the DSDT Reconfigured the config.plist to and removed some flags which weren't needed because of the DSDT added the InjectATI + Ornioco Framebuffer (I removed the Orinoco framebuffer because of some weird glitches but it might be useful for other AMD GPUs if you inject the correct framebuffer according to your GPU. No need to inject anything for nVidia GPUs unless your GPU needs it) Added the InjectIntel + ig-platform-id for my intel HD530 (for intel HD 530 I use the 0x19120001 ig-platform-id) Removed com.apple.finder.plist Removed com.apple.QuickLookDaemon.plist rebuild the kextcache and reset the nvram
Steps 5 to 7 might not be necessary I just did them anyway, if anyone succeeded to get quicklook working without those steps let me know so I can exclude those steps.
Also confirmed to work with AMD R9 270X on a SandyBridge rig (without an iGPU) using WhateverGreen + Lilu kexts, which also helped to solve the transparency issue along with the Quick Look problem, it also resolved the buggy Screen Capture (Command+Shift+5) issue as well.
nvram cleanup kextcache & prelinked kernel rebuild reboot
More info on that here.
This is what I needed for my NVIDIA rig and the MSI motherboard in the signature. Your milage may vary, depending on your hardware. But, the idea should be the same regardless.
Set your BIOS to use PEG (dedicated GPU) so you can boot.
Since you're reading this, chances are that you're already connected to the dedicated GPU and the BIOS is set to PEG. So just go into BIOS and see if you're using the iGPU or the dedicated (PEG) graphics device by default.
If you're already using this, skip to Step 3 (the part AFTER Reboot). Reboot (I think you don't necessarily need to boot into the OS...but you do need to reboot at least until Clover UI) Reboot back into BIOS and set it from PEG to IGD (integrated graphics) WITHOUT removing the cable. Reboot again.
The result should be that the OS is tricked into thinking you're booting with the IGPU when in fact you're using the dedicated GPU.
You will also need to patch the iGPU from Clover config.
1. Graphics -> Inject Intel (UNCHECK Inject Nvidia or ATI if it's checked).
2. ig-platform-id (in my case for Intel HD 4600 Desktop) it was: 0x0d220003
And use IntelGraphicsFixup.kext in Clover/kexts/Other. In my particular case, without the kext, I would get freezes in Safari.
This might be a bug with Mojave and it could be fixed by Apple in the future. but in the meantime, feel free to use this if it helps you fix the issue.
I wanted to push watercooling to the most. Silent. Level. possible.
While gaming and also for working.
Quite a challenge and a lot to learn.
Thoughts on water-cooling:
It always depends on the use-case if water-cooling is more silent than air-cooling.
My personal experience:
Air-cooling is more silent in idle load scenarios (when you just do some easy tasks like browsing or office) Water-cooling is more silent for constant high load (e.g. when you are gaming/working for long times)
Tricks to get the water-cooling as silent as possible:
Configure the BIOS to turn off the radiator-fans in Idle load scenarios. That leaves only the pump running. Undervolt the pump (to e.g. constant 7V).
This works best, if you can plug the pump into a fan or pump header and assign a constant (lower that 100%) speed to it in the BIOS.
If your BIOS does not allow that, you could use a resistor-adaptor to slow it down.

Ciao mi scuso per il disturbo, io vorrei abilitare la mia scheda grafica Nvidia geforce gtx 950m per avere delle prestazioni migliori quando lavoro su after effect, la scheda Intel non è ha abbastanza memoria non so se sia possibile fare qualcosa, spero possiate aiutarmi, vi lascio delle info.
Sistema operativo Mac osx sierra 10.12.6
Modello laptop : Asus N551jx-cn043t
Il resto è nella screen
I want to install High Sierra.
I can get into the installation screen,but after the installer in my USB flash put something into my internal disk and I booted to "install macOS from internal disk",the following error occurred:
my EFI is in EFI.rar
my error log is in Installer Log.txt.
How to fix this problem?
I was able to successfully install OS X High Sierra on a 8700k with a GTX 1080Ti
Everything seems to be working fine but I've been reading on other people suggesting to make sure hardware acceleration *is* working fine.
I installed the web drivers for nvidia (and disabled SIP after installation)
Web drivers version: 3126.96.36.199.35.106
CUDA Driver version: 396.64
OS X system version is 10.13.5 (17F77)
After installing the latest CUDA drivers, I was able to select the GPU option in "ray-trace" in After Effects (preferences > previews > fast previews > GPU Information...)
I'm not sure how else am I able to test whether the GPU acceleration in other applications is enabled and running properly?
PS: I don't have final cut pro so I'm unable to test that application...
PS 2: ig-platform-id in config.plist is set to 0x59120003
