What's the model of your wifi card ?

@dadabla glad it's working for you! What is the exact model of your wifi/bt card ?

Generate your own serial with GenSMBIOS and enjoy your laptop For Intel wifi/bt you need to put appropriate kexts for Ventura. I don't have such wifi/bt card. Dell 7490 OC 0.8.6.zip

+1 Everything's working super smooth on my Dell 7490. Thank you!

0.7.8

Where it stuck exactly ?

@Hack.intosh AvoidRuntimeDefrag=False -lilubetaall updated whatevergreen.kext

My laptop freezed couple of times already but I am not sure if the problem is related to the fact that I am loading the OS from external drive through USB 3.0 port or something else. Still fighting with the mini PC to get pass the "AppleStoreKeysTest" stuck.

I installed it on my 8th gen intel Dell 7490 and it actually runs pretty smooth. Applied suggested settings in OC + updated watevergreen kext. Next few days I will test more and share the results. Also tried to install it on my ProDesk but it stuck on nvme check. I didn't have time to debug deeper.

Just a quick update for those of you who wants to install older MacOS version like Mojave, Catalina and BigSur. Today I tested all three versions and they work great. With my EFI posted above I was not able to see any SATA drives in OC so here's how I fixed it. I put the patched CtlnaAHCIPort.kext in kext folder and config.plist - CtlnaAHCIPort.kext Change the following settings in config.plist as per OC install guide - OC can't see macos partitions ScanPolicy set to 0 EnableJumpstart: YES HideVerbose: NO MinDate: -1 MinVersion: -1

Correct! I'm using DP to HDMI cable and it works perfectly with audio both left and right DP. On my EliteDesk I have 3xDP.

Sure! First I started with EFI from my HP EliteDesk 800 G5 DM as it is very similar to HP ProDesk 400 G5 DM. Both 9th gen Intel i5 with intel UHD 630 iGPU (Thanks @Hervé for the correction). Of course there are couple of differences like the chipset B360 vs Q370, second nVME option for EliteDesk , integrated LAN etc. I tried different system definitions and ended up with Macmini8,1 (previously used iMac19,1 and 20,1 - caused unresponsive usb's with the current mapping). Originally ProDesk was equiped with Micron 2200 NVME SSD and keep in mind that it will not work in MacOS (in case anybody missed the anti-buyer's guide) so I used one of my Kingston A2000 500GB NVME SSD. Just want to mention that this is one of the best options for laptops, micro and mini systems with bad airflow because it has great operating temperatures. I've used 0.5mm thermal pad so the ssd never reach more than 55'C under load! Heading to EFI changes first I had to change the Ethernet LAN kext for ProDesk - RealtekRTL8111.kext. Since my EliteDesk is 100% working both DP with audio I just decided to copy the whole Device Properties section and voila - worked on my ProDesk like a charm! I had to disable SIP so I can use TP-Link T3U Wireless usb adapter. OpenCore is updated to version 0.8.0. These small systems are great for casual everyday tasks. Depends on the CPU and amount of RAM results could be very impressive. Writing from it now under MacOS Monterey 12.4. Didn't tried earlier versions with current EFI. Cinebench R23 results: Single Core - 963 / Multi Core - 4680. Max temperatures ~83'C , Idel temperatures ~43'C. Thermal paste - Thermal Grizzly Krayonaut. Enjoy!

Thank you @Hervé ! I managed to fix it. Started from scratch and fixed everything. Now it's 100% working - sleep, power management, all usb ports, both DP with audio etc. You can mark it as solved

Hi everybody! Last few days I have in my hands this little beauty - HP ProDesk 400 G5 Mini equiped with i5 9500T , HD 630 , 8GB DDR4 and 500 GB NVME. I managed to install the latest Monterey 12.4 and it seems to work pretty well. Still I have two unsolved problems. 1. Only one DP is working (hot plug) and the other one doesn't respond after OC starts to loading the OS. Is it possible to make it work both DPs so I can use a dual screen setup ? 2. Front left USB is not working. I tried to remap with Hackintool but it doesn't appear at all. This is a minor problem as I only need 3 USB's but if it's possible to make it work will be cool. I will deeply appreciate a little help from the masters here @Baio77 @Jake Lo @Hervé @Bronxteck Here's my current EFI and ioreg EFI.zip HP ProDesk 400 G5.ioreg

I suggest you start from scratch including BIOS settings and write down exactly what you do otherwise nobody will be able to help.

@gemino Check your cloud storage. Uploaded EFI to try with the Broadcom card

@gemino Done! Hope it works for you. Cheers

Give this a try with Intel WiFi - https://drive.google.com/file/d/1mlQj0mnvfp6VyaT8QtC1z5p6AllGpDC0/view?usp=sharing

Glad you made it! Don't forget to generate your own serial number. Good luck!

@juico Thanks! I can assist in testing stuff under Mojave. Still have my test nvme drive so I can provide help.

I would love to go back to Mojave as I can use some 32bit apps and games. Unfortunately with my current EFI I cannot manage to make system working stable enough and frankly not sure where to start.

I tried Mojave and Catalina on my 7490 and the buttons didn't work for me. It's working only Big Sur or newer. Maybe @juico , @blankmac can help to solve this OS compatibility problem.

Pinch zoom works only horizontal on my 7490. Still a huge progress since last few months thanks to the people in the forum @juico , @Lorys89 , @Jake Lo , @Hervé and many others.
