MAHDIANO Posted April 19, 2020 Share Posted April 19, 2020 After hours and hours spent to properly setup a nearly-fully functional MacOS over Dell Latitude 7490 with partially working Intel WiFi (still kext under development, very unstable). First, thanks to full detailed guide by Hervé. My Latitude 7490 has: BIOS v1.13.1 Intel Core i5-8350U Intel UHD620 Graphics and Full HD non-touch display 16GB RAM M.2 2280 NVMe TOSHIBA 256GB Intel Dual Band Wireless-AC 8265 802.11a/b/g/n/ac + Bluetooth 4.2 It runs macOS Catalina 10.15, Clover 5112, disabled DSDT.aml (caused endless reboot loops "Memory panics") Everything works as per the guide except: Wifi Bluetooth (Intel Dual-band Wireless AC- 8265 module) Installed IntelBluetoothFirmware kexts, added to attachments I didn't perform deep research about Intel Wifi / Bluetooth drivers not supported by macOS which is very disappointing. In this post I am going to explain how I get WiFi enabled (partially) in addition to certain questions open for community. Preloaded kexts Those 3rd party kexts loaded after booting process, excluded some installed apps. DSDT.aml What is for and removing it will cause any interruptions? I notice some Fn are not working like brightness levels, search, lock, is there any updated/working DSDT for Catalina? PCI Serial Adapter (22) Wondering which PCI-Serial 22 modem is this? Any of provided kexts or hardware cause this? Apple Intel Wifi Unconfirmed group of developers released a website with repo for Intel Wifi drivers. Attached an earlier release (that actually worked partially with me). As the kext repo is under development and highly unstable, it's loaded manually after booting, not added to EFI/kexts/Other nor loaded in L/E (proven crash of OS). To Run AppleIntelWifi kext 1. Navigate to extracted kext from Terminal. 2. Run the following commands: sudo mv ./*.kext /tmp sudo chown -R root:wheel /tmp/*.kext sudo kextload /tmp/*.kext Now it's loaded. What it can do 1. Turn On/Off Wifi adapter 2. Scan for Wifi networks (2.4 and 5GHz bands) 3. Add manual networks 4. Manually configure Wifi settings 5. Show saved networks (from other Apple profiles) What cannot do 1. Cannot connect WPA/WPA2 APs, it always think that network settings fallback to WEP which is unsecure then it would never accept connection Untested 1. Setting WEP connection on WiFi router/AP and test Trackpad Buttons Any clue how to run at least a button from Alps Trackpad or remap a keyboard button to work instead? I have.to use external mouse every time I need to click a button. AppleIntelWiFi 0411.kext.zip IntelBluetooth.zip Link to comment Share on other sites More sharing options...
