Thanks, Merci Hervé! your update on the BCM4350 guide was very helpful. As I can confirm the dw1820a chips that have the label CN-08PKF4-xxxxxxx should be avoided. Right now, I found an old dw1560 and replaced the CN-08PKF4 dw1820a card, world is good! So long journey, but for any future google searchers, go with dw1820a with # CN-0VW3T3 as Hervé suggested specifically. Looks like all Brcm/dw1560 chips are in China/Hongkong as far as eBay goes Good day.

Installed dw1820a as I saw below from Herve and wanted to try it out on e7450. https://osxlatitude.com/forums/topic/11322-dw1820a-broadcom-bcm4350-chipset-under-high-sierramojave/ The way this was as done is by "removing AirPortBrcmNIC plugin kext from IO80211Family kext, patching AirPortBrcm4360 plugin kext with the id of the DW1820A" . It recognizes the chip and for 5-10mins it works but then freezes the whole system. I did not feel like I needed AirportBrcmFixup kext, so ignored installing it. Rest of the system is working, I don't really need BT.. Internet works with Ethernet cable, usb hotspot etc. But when I turn on the wifi with dw1820a, works at full blazing speed (5ghz channel) and after some time it freezes. Attached are the system debug files (EFI, IOreg dump, and LE folder) Appreciate if I can't get any pointers to resolve this .... TIA btw, the sys report on wifi dumps this ('switched off the wifi) ========== Software Versions: CoreWLAN: 13.0 (1370.8) CoreWLANKit: 13.0 (1370.8) Menu Extra: 13.0 (1376.3) System Information: 12.0 (1300.2) IO80211 Family: 12.0 (1200.12.2) Diagnostics: 1.0 (805) AirPort Utility: 6.3.9 (639.9) Interfaces: en2: Card Type: AirPort Extreme (0x14E4, 0x23) Firmware Version: Broadcom BCM43xx 1.0 (7.21.190.33 AirPortDriverBrcm4360-1325.2) MAC Address: 30:52:cb:82:43:47 Locale: FCC Country Code: US Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165 Wake On Wireless: Supported AirDrop: Supported AirDrop Channel: 0 Status: Off debug-1820a.zip

Jack, Big Thank you!!! Looks like the older version of the Clover was the culprit. Thanks again! You are the expert :)) Thank you.

Appreciate if I can get any pointers, please From Mojave 10.14.2, I updated to 10.14.4 but now having boot issues Specifically I get [igpu] Unable to load frame buffer kextd stall AppleACICPU This m/c is e7250 w ssd , attached is the EFI CLOVER. Many thanks in advance EFI7250.zip

Many thanks, but I figured out that duplicate kexts in /L/E are the culprits. I took a backup and removed most of the kexts except the two in your EFI (copy to /L/E). Now it is super fast boot within 20 secs Good day.

Just replaced the config.plist, ACPI and kexts folders in the existing EFI from your EFI_7440Mojave.zip Works like a charm. Thanks again Jack. If I may ask one last followup, boot up seems longer (may be there are some timeouts for which boot sequence is waiting, not sure), any way to troubleshoot the longer boot sequence? I can definitely live with 2 min boot time, though Good day.

Thanks and I will get started and keep you posted. Good day.

Thanks so much Jack! Attached is the CLOVER folder under EFI PS: I am a total newbie on this I stay tuned. CLOVER.zip

Appreciate if any SME can point me in the right direction: Have an e7440 ; has everything running Mojave and Clover Screen is bright with no brightness control in the "display" of system preferences No audio detected Here is what I see on system info === Intel HD Graphics 4600: Chipset Model: Intel HD Graphics 4600 Type: GPU Bus: Built-In VRAM (Total): 4 MB VRAM (Dynamic, Max): Vendor: Intel Device ID: 0x0a16 Revision ID: 0x000b Kernel Extension Info: No Kext Loaded Displays: Display: Resolution: 1366 x 768 (WSGA - Wide eXtended Graphics Array) UI Looks like: 1366 x 768 Framebuffer Depth: 24-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes Automatically Adjust Brightness: No ==== Every thing else is working. Many thanks in advance.
