majora Posted February 20, 2023 Share Posted February 20, 2023 Hello, my question is about this wifi card DW1520 ½Min PCIe 14e4-4353 BCM43224. I used this card successfully on macos big sur with the help of MBA5,2/Brcm4360 patch from this topic. But when I try to implement the same in macos monterey I get kernel panic. Is there any solution for this card and monterey? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 20, 2023 Administrators Share Posted February 20, 2023 You'd have to explain in details the various steps you followed to try and recover support for your DW1520 card in Monterey but, as stated here several years ago, Big Sur dropped support for Broadcom BCM43224 chipset so follow the suggested/recommended procedure to try and regain support for your card.

majora Posted February 22, 2023 Author Share Posted February 22, 2023 I used this card in big sur with IO80211Catalina.kext and the patch "AirPortBrcm4360 kext for unsupported Mac models" in this forum, where everything is perfectly explained. In big sur everything is fine and the card works. But when I do the same in monterey it gets kernel panic. If I remove the IO80211Catalina.kext monterey starts normally. Apparently in monterey the patched kext doesn't work and I'm trying to find out why. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 22, 2023 Administrators Share Posted February 22, 2023 So, what you actually do is binary patch the AirPortBrcm4360 PlugIn of that IO802Catalina kext, right? What patch do you apply? For what target SMBIOS model? Link to comment Share on other sites More sharing options...
majora Posted February 22, 2023 Author Share Posted February 22, 2023 Yes, exactly. I used SMBIOS for MacBookPro12,1 with these patch: Find: 4D61632D32453646414239363536364645353843 Replace: 4d61632d45343343314332354434383830414436 But then I tried without patch with the original IO80211Catalina.kext, smbios MacBookAir5,2 and boot-args "-no_compat_check". In both cases I got a kernel panic. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 22, 2023 Administrators Share Posted February 22, 2023 Then I guess the old patched kext has had its time... Try OCLP as alternative. Link to comment Share on other sites More sharing options...
majora Posted February 23, 2023 Author Share Posted February 23, 2023 I tried using OCLP but it doesn't see my wifi card and says there is nothing to patch. Many thanks for trying to help and much respect to you for sharing your knowledge! Only in this forum I found how to patch IO80211Catalina.kext and everything works fine in big sur.

Administrators Hervé Posted February 23, 2023 Administrators Share Posted February 23, 2023 According to kronokernel, patch for BCM43224 still works in Monterey (or, at least, it did in the summer of 2021 and Monterey beta days): https://forums.macrumors.com/threads/macos-12-monterey-on-unsupported-macs-thread.2299557/post-30034783 https://forums.macrumors.com/threads/macos-12-monterey-on-unsupported-macs-thread.2299557/post-30038647 I've not looked at what the OCLP solution does in that respect but, assuming it breaks the seal and somehow copies the necessary kext in /L/E or /S/L/E for caching, then the on-the-fly patch (in the bootloader's config file) would work. You'd have to target MacBookAir5,2 or MacBook7,1 for OCLP to install the necessary kext and patch macOS accordingly. Link to comment Share on other sites More sharing options...
majora Posted February 24, 2023 Author Share Posted February 24, 2023 Yes, I tried with smbios MacBookAir5,2 and the OCLP gives a message that there is nothing to patch. Maybe OCLP doesn't work with hackintosh. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 24, 2023 Administrators Share Posted February 24, 2023 It's not meant for Hackintosh but for real Mac computers; hence why you have to use it with outmost care... Link to comment Share on other sites More sharing options...
