MacOS Sequoia 15.7.5 killed Continuity on my Hackintosh

Here are the updated PR files you requested (current config.plist and fresh IOReg) after applying your previous checklist. Both validate correctly with ocvalidate.

I have also extracted a DMAR.aml under Windows using SSDTTime with VT-d enabled in BIOS, but I have not modified or added it to OpenCore yet. I will wait for your instructions on how exactly to patch and use it.

Still a couple of issues. Make the following changes:

- Enable ExtendBTFeatureFlags and Remove ProvideCurrentCpuInfo
- Kexts loading order is not correct.
- You were asked to remove the Kernel patches as you're already using a supported SMBIOS.
- agdpmod=pikera shouldn't be required for your hardware.
- RestrictEvent patching is not done correctly.
- Drivers loading order is not correct. Mandatory drivers should load first.
- Follow the VT-d implementation guide. Just a quick tip - Your DMAR table has two memory reserved region. Patch it and you should be good to go!

I have a question about my DMAR table. In the hex/decoded view I see two reserved memory regions:
– Base 0x00000000B182C000 – End 0x00000000B184BFFF – PCI Path 14,00
– Base 0x00000000B3800000 – End 0x00000000B7FFFFFF – PCI Path 02,00
You mentioned that my DMAR table has just one memory reserved region to patch. Which one exactly should I remove and which one should I keep?
Also, when I try to compile the edited DMAR.dsl with iasl 20251212 on two different Macs, iasl hangs and never finishes. Could you please compile the corrected DMAR.dsl into SSDT-DMAR.aml for AppleVTD for me?

Delete line 70-101 in the original DMAR table and then compile. Should get compiled. You still have to drop the OEM DMAR table and then inject the patched one.
