I have a HP450-G4 Laptop with Mojave 10.14.6 / Lilu / Whatevergreen / SSDT-PNLF. I just changed its awful LCD TN panel for an IPS one (AUO B156HAN01.1).
What happens now is (no software changes, just changing the panel), the monitor is black until I move the brightness slider to its maximum setting. Any other setting generally show a black screen or a weird slow flicker. It worked fine with the TN panel.
If I enter sleep and resume, brightness works again until the next reboot.
Things I have tried:
- Injecting the monitor EDID (AFAIK shouldn't be necessary as it is correctly detected by Clover and IOREG dumps it correctly)
- Injecting a patched EDID with Apple Product ID using the different tools I found here (a ruby script, a shell script, FixEdid application). Strangely, with most of the patched EDIDs, computer is then not able to sleep (sleeps but instantly wakes up), and even display colour artifacts during the second stage boot.
- Adding the generated EDID plist from FixEdid app on AppleBacklight.kext overrides in S/L/E. Same than previous point, either computer does not sleep or artifacts during second stage.
- Followed guides for AppleBacklightInjector / AppleBacklightFixup disabling WhateverGreen patches for backlight. Not working, not even know if those are related because the PNLF device already exists and the slider is there, and most of them seem outdated now that WhateverGreen does most things by itself.
- Used WhateverGreeen parameter igfxcflbklt=1 to apply backlight patches for Coffee-Lake. With them, brightness is always 100% regardless of slider. I didn't expect this to work as this is a Kaby Lake laptop, just tried it out of desperation.
So the problem is, I don't know what is my problem (EDID/DSDT) or what more things to try. I am lost. Any pointers appreciated. Please find attached my EFI folder with SSDT-PNLF, config.plist, etc...
My rig is working great driving a single display from Vega 64 via DisplayPort, but I'm having a devil of a time getting a TV monitor working via HDMI on the same card.
My TV lights up an input icon when I plug it to the Vega (see attached--notice the next port w/ nothing plugged in is grayed out). So I know some electrons are flowing (maybe EDID?), but it never gets a signal. I've tried several HDMI 2.0 cables.
I'm running a vanilla install of 10.14.6, as iMac19,1, with just Lilu (1.3.8) + Whatevergreen (1.3.1). System recognizes the Vega and seems to be correctly using the UHD630 headlessly. I just can't get HDMI out of the dGPU...
I've tried the "-raddvi" and "agdpmod=vit9696" boot args, no dice. I've tried the kext patch workaround for disabling board verification, also no go (not surprising as I think that method is now obsolete for my setup).
I hit the same wall running 10.14.2 as iMac18,3 with a different platform-id before updating.
Here's my whole EFI.
Any assistance at all is hugely appreciated!! Thanks y'all.
Long time no see guys!
As you can see I am not new user of Insanely and do not want to post in incorrect section, but I can not find any similiar topic at all. I,ve searched the forum and the web and I can't find a solution.
My question is that is there any possibility to install Mavericks 10.9.5 on external drive on the newest Macbook Pro 13 from 2018? I know that the Intel Coffee Lake is new generation of CPU's and there is no drivers in Mavericks system to run this CPU, but I was thinking about it alot and I decided to write here. Because if we can install all the newest OSX, macOS on older machines then maybe we can install older systems on newer builds?
P.S. If I wrote in incorrect topic then please move this thread to the right section, I will be grateful
Salve, vorrei fare un Hackintosh come da titolo, solo che avendo poco budget volevo chiedere se la mia attuale postazione fosse buona e ci fossero componenti compatibili per mac:
amd r9 280x
ram 2x4 1600
Se non erro però la gru non dovrebbe esserlo dato che è amd. Grazie in anticipo
