benz_738 Posted November 20, 2023 Share Posted November 20, 2023 (edited) Hi, I'd like to share my Opencore configuration. In my opinion it can be considered as 100% working, but let me know if you find any problems. This setup will use the internal GPU, the only part that may still give you problems is the secondary monitor. macOS Version: Ventura 13.6.1 Model: iMac 18,1CPU: i7-7700 (displayed as i5) RAM: 2x DDR3 Kingston HyperX Fury 8GB GPU: internal - Intel HD Graphics 630 Storage: M.2 SSD (Western digital) Audio: Internal - Realtek ALC892 - rear and front panel connections working Ethernet: Intel I219-V - Working (IntelMausi.kext) WiFi and Bluetooth: original Apple Airport card (chipset: BCM94360CS2): you can find many of them on ebay An Apple airport PCI express internal adapter must be used to install the Airport card. This will enable both connections natively. USB Mapping: kext included, all ports configured Resources must be copied from the second archive into your EFI/OC folder (it's ready to copy). It will show up the OpenCore GUI on boot. Important 1. This configuration doesn't need you to power cycle the monitor on login! 2. Waking up from sleep worked only once 3. Check the resolution of the OpenCore boot menu, it's probably different in your system 4. You must follow these instructions to generate your hardware serial identifiers (remember to select iMac18,1 as model name!) 5. I've used the same setup with an external GPU (Radeon RX480), you can try with this config, but remember to change the model name to 18,2 or 18,3 - some info here Opencore configurator is highly recommended: download Dont' forget to let me know if this configuration helped you, it required a lot of time to tune everything 🙂 Good luck!

benz_738 Posted December 7, 2023 Author Share Posted December 7, 2023 I've noticed that this configuration is lacking the USBMap.kext file. I'll re-generate and upload the file as there's an high chance that the sleep function doesn't work for that reason. Link to comment Share on other sites More sharing options...
Slice Posted December 29, 2023 Share Posted December 29, 2023 First. shown i5 instead of i7 means your mistake in config.plist: CpuType. Second, I think this is just misprint. You wrote DDR3 while it should be DDR4. Link to comment Share on other sites More sharing options...
