Hey guys, did anyone successfully flashed the TB firmware chip on this MOBO? I read several times on this thread that it is not recommended, but I did not get why. I did it many times before on a GA Z490 vision D board with very good results and I would like to recreate same nice build with this...

Dear CaseySJ, I don’t see the OC 0.6.5 EFI folder with the updated Alpha Intel WiFi drivers. Could you upload it again please? Thank you

I think the same, my LuxMark Scores even improved with the update!

Geekbench 4 CPU score increased from 36k to 41k (i9-9900K @ 5GHz, iMac19,1 SMBios)

BruceX test with ProRes422 is slightly faster under 10.14.4 than 10.14.5 (11-12s vs 13s)

The same under Mojave 10.14.4: Gigabyte Designare Z390 i9-9900K @ 5 GHz 64gb G.Skill Ripjaws V DDR4-3200MHz CL16 Sapphire Radeon Nitro+ Vega64 8GB Samsung 970 Pro 512GB (M.2 PCIex 4x) Mojave 10.14.4 Final Cut Pro X 10.4.5 iMac19,1 SMBios Prores 422 - 11-12 seconds H.264 - 14-15 seconds

Gigabyte Designare Z390 i9-9900K @ 5 GHz 64gb G.Skill Ripjaws V DDR4-3200MHz CL16 Sapphire Radeon Nitro+ Vega64 8GB Samsung 970 Pro 512GB (M.2 PCIex 4x) Mojave 10.14.5 Final Cut Pro X 10.4.5 iMac19,1 SMBios Prores 422 - 13 seconds H.264 - 14 seconds

Geekbench 4 OpenCL Score dropped from 200k to 144k on my Sapphire Nitro+ Vega 64 Anyone with similar issues? Someone can test BruceX on the new release for performance drop? BTW, same purple stripes here

My Serial also ends with JV3Q and my hack is detected like iMac 27" in iCloud

DexterOX, I think that you mean the SMBios serials generated by CloverConfigurator? This is mackie100 who is developing it. https://mackie100projects.altervista.org/download-clover-configurator/ Clover just injects the serial which you gives to it...

Thank you for looking up the URT devices! Could you please search the ioreg for the other adresses: @15 @15,1 @15,3 @19 @19,1 @19,2 @1E,2 @1E,3 @12,6 And open up the URT devices to see what is inside? Some other devices attached to them?

Oh.. ok, that would be so great !

DexterOX, how does the IMEI device look like? (device-id, etc) Are the URT0/URT1/URT2 devices present in the DSDT? Are in your iMac 19,1 DSDT following adresses present and assigned to which devices? 0x00150000 0x00150001 0x00150003 0x00190000 0x00190001 0x00190002 0x001E0000 0x001E0001...

I understand, but the DSDT and the SSDTs looks the same for all the iMacs 19,1 with the same processor/configuration so no sensitive/personal information will be shared. The serial numbers are inside the SMBios

Could you share the ACPI and IOReg dump a real iMac 19,1 please? I would like to optimise the DSDT of my hack and I hardly need this dump for this! Thank you

Hi RehabMan and thanks for your work so far! Please clear me up, on a 8 Series mobos under Sierra it was enough to edit the DSDT to exclude the unused HS+SS ports to have the total number of 15 ports and rename the device to XHC. This way no kexts or patches were needed. Could you clear me up...

yes, as far that I know, this is quite normal as the OS works internally more with the BoardID as with the product name. Are there already some dumps of iMac 19,1 SMBios around? My question is more of the kind if the new 10.14.4 update already supports new iMacs? That means, if you can create...

Is the iMac19,2/3 SMBios included or recognized with the new update? (10.14.4) or do we have to wait for the next updates in order to use it?

Intel HD6000+/HD5000/HD4600+/HD4000/HD3000 Framebuffer Edits Hi Toleda how can I change the memory size of HD4600 framebuffer to have 4K output on Display Port? My mobo is capable of 4K via DP and I am running Mavericks. I found this post, but it seems to be only for 10.10+ as i do not...

Me neither, I dont like Yosemite and I am staying with mavericks until some better os will come... And like you I want to be able to use recent hardware under Mavericks. The problem you get is, I suppose , that the Nvidia kext you managed to install is built against some graphics headers...
