    The 4K Dell OptiMac - 9020 MT - Core i7-4790 - Radeon RX 570 - LG 4K IPS Monitor

    I am in particular interested in how did you get the bluetooth to work on the card on USFF as you mentioned only WIFI works initially and BT was not recognized ?

    While accommodating the newly acquired graphic card in the PCIe x16 (blue) slot, I have to move the NVMe PCIe adapter to the x4 (black) slot. That results a noticeable SSD performance impact. With a WDC SN520 256GB spec 1700/1300MB/s(R/W), I got 1600/1260MB/s on x16, but only 760/710MB/s on x4...

    heat from NVMe adapter and graphic card both contribute to this. It makes more sense to use graphic card in a MT.

    It looks like a full height card. It won't fit in SFF. FYI, when I have the Yeston RX 550 in 7020 SFF (along with another PCI NVMe adapter), the fan seems to be running at high speed constantly, not sure it's from the system fan or graphic card. On 9020 MT, the fans stay quiet.

    I ordered one from aliexpress on 4/13. It finally came today 5/29. Tried it on a 9020 MT i7 4790 (Catalina) also 7020 SFF i5 4590 (Mojave), with factory PSUs, all work out of the box with no configuration changes. It was recognized as RX 550 / 4GB. 4K thru HDMI on LG 4k monitor seems to be as...

    I second this as I encountered the same issue and solved it by following this - adding apfs.efi into CLOVER/drivers64UEFI/. However I kept ApftDriverLoader there, not sure if that is good or not. Another interesting finding, the USB installer can recognize the MVMe drive (without apfs.efi) if...

    "/var/vm/sleepimage" is a directory. "sudo rm /var/vm/sleepimage" causes errors. Should "sudo rm -r /var/vm/sleepimage" be used with the recursive option instead ?

    << Solved >> Dell Optiplex 7020 - 4K monitors on Intel 4600 Integrated GPU

    I lost 4k after updating to macOS 10.14.6 today. Tried to fix it by "touching" config.plist, that did not work. Updating to the latest Lilu (v1.4.0), Whatevergreen (v1.3.5) fixed the problem.

    I was able to make this work on my LG 24" 4K Model 24UD58. A few notes. * both CFG Lock and DVMT Pre-Allocated were 0x1 before the changes were made. * To increase video memory to 2GB, I have to use method A, manually changing config.plist as I don't find any "PciRoot(...) entries under...
