<< Solved >> No 4K resolution on HD4600

[cci[RR]us]

I saw that - hence my question - you say you changed it to iMac15,1 but do not say if you kept that or reverted to MacPro6,1 Edited to add: I see some screenshots with MacPro6,1 and then later ones with iMac15,1. Do you have success with both or just one of them?

Ah, I understand your confusion now. I just checked my settings. It is currently iMac15,1. Sorry, I don't remember what happened during MacPro6,1.

Yes! With the new v1.31 drivers (dated 31 Dec 2018), I get 4K resolution now! View attachment 384658
Thank you for your help!

Just to summarize: no "Inject Intel", empty ig-platform-id; simply install the latest Lilu and Whatevergreen to /L/E and I get the full range of resolutions!

I am using the core i7 4790k which have intel hd4600. Can you please post your clover config file?

Just a note to say Ive been thru a similar process to get a Dell 7020 working with 4k on a HD4600 and on that otherwise fully working machine there were 3 things that needed looking into;
1. Cables - the Dell would only work reliably at 4k with DP to DP cables
2. Bios/Uefi - The dell Bios didnt allow;

• the setting of DVMT to 96MB (64 seems the minimum that some reported success)
• Disabling CFG Lock

So the dell required setting these parameters by writing directly to the UEFI using a special boot process.
3. Kext - AppleIntelFramebufferAzul setting was needed

There was also a method of increasing GPU RAM to 2GB.

same issue here - no 4k with:

• CPU: Intel Core i7-4770k
• Motherboard: GA-Z87N-WIFI
• about mac:
  • iMac (Retina 5K, 27-inch, Mid 2015)
    3,49 GHz Intel Core i7
    Intel HD Graphics 4600 1536 МБ
• max resolution: 2560x1440
• MultiBeast: 11.3.0-4
  • WhateverGreen: REL-129-2019-05-24
    Lilu: REL-136-2019-05-24
    iMac14,2

What I did:

• manually updated WhateverGreen to 1.3.4
• changed id in Multibeast to iMac15,1

Unfortunately, still no 4k

Any hints highly appreciated! Thanks!

UPDATE:
upgraded WhateverGreen to 1.4.0 and Lilu to 1.4.5 - no 4k, still max: 2560x1440

UPDATE #2 - SOLVED:

• mounted EFI partition via Clover Configuration
• added the following into /Volumes/EFI/EFI/CLOVER/config.plist (section <key>KextsToPatch</key>):

                        </dict>

reboot -> 4k!

UPDATE #3 - BROKEN
OS update to macOS 10.14.6 (18G6020) broke 4k: resolution stuck at 1920x2160, boot parameter "-cdfon" does not help
Never ending story...

UPDATE #4 - SOLVED
WhatEverGreen 1.4.1 - fixed the previous issue
Note: do NOT use "-cdfon" boot parameter (suggested in other thread), monitor is flickering when it is active.
