  1. My EM7305 (DW5809e) is working with kext posted here.
  2. I've tried a few other configurations from some of the other natively supported Sierra GSM WWAN cards, but still nothing more than showing up in the System Report > Network > WWAN. Also checked to verify that all of the AT commands work with the DW5811e (Sierra EM7455) which they appear to. Seems to be a Qualcomm MDM9230 chipset, so going to see what other supported cards I can pick profiles from.
  3. Have got one in there but still doesn't populate in the Network PrefPane.
  4. After having to re-install I tried modifying the CellPhoneHelper.kext and managed to get the DW5811e to show up under System Report > Network > WWAN, but it still doesn't seem to appear in the network settings menu. I presume I've probably misconfigured the CellPhoneHelper.kext as I copied the Sierra Wireless AC 595 Modem kext and modified it to pick up the DW5811e but that uses CDMA instead of GSM. I suspect having the "ActivatorPath" set brought the WWAN card online but that the other misconfigured options are the reason Mac OS isn't picking it up correctly. I'm going to try adjusting it and will come back with what happens! Here's the key I've added to the Info.plist inside the CellPhoneHelper.kext: <key>0x413c/0x81b6 Sierra Dell DW5811e</key> <dict> <key>CFBundleIdentifier</key> <string>com.apple.driver.AppleUSBHostMergeProperties</string> <key>IOClass</key> <string>AppleUSBHostMergeProperties</string> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>IOProviderMergeProperties</key> <dict> <key>DeviceModemOverrides</key> <dict> <key>ConnectionPersonality</key> <string>Sierra CDMA Personality</string> <key>ConnectionScript</key> <string>WWAN.ccl</string> <key>DeviceModel</key> <string>CDMA</string> <key>DeviceVendor</key> <string>Sierra Wireless</string> </dict> <key>DevicePPPOverrides</key> <dict> <key>LCPMTU</key> <integer>1450</integer> </dict> <key>EndpointMapping</key> <dict> <key>82</key> <string>wwan</string> <key>84</key> <string>wwanCNTL</string> <key>85</key> <string>wwanGPS</string> </dict> <key>InfoCommands</key> <dict> <key>ATCommands</key> <dict> <key>ESN</key> <string>+gsn</string> <key>Manufacturer</key> <string>+gmi</string> <key>Model</key> <string>+gmm</string> <key>ModemSW</key> <string>!mdmver</string> <key>PRL</key> <string>!prlver</string> </dict> <key>HiddenProperties</key> <dict> <key>ActivatorPath</key> <string>/Library/Application Support/SierraWireless/SierraWWANActivation.app</string> <key>CommandPortBaseName</key> <string>wwan</string> <key>ControlPortBaseName</key> <string>wwanCNTL</string> <key>DataPortBaseName</key> <string>wwan</string> <key>StatusType</key> <string>SierraCDMA</string> </dict> </dict> <key>Initializing</key> <true/> <key>WWAN</key> <true/> </dict> <key>bcdDevice</key> <integer>2</integer> <key>idProduct</key> <integer>33206</integer> <key>idVendor</key> <integer>16700</integer> </dict>
  5. Tl;dr learn from my mistake: Don't mess with iCloud, unless you've really lost your laptop. Yesterday I tried to activate Lock Mode to test it(!) and the OS rebooted back into Mac OS without any issue, unlike my iMac which rebooted into the "This Mac has been locked" screen. So I thought nothing of it. Until today where I was going into the installer to access Terminal and the lock screen popped up, though the PIN I set didn't work and iCloud didn't recognize the laptop as locked. Oops. Things I tried: - Wiping the OS = Still locked. - Removing the battery and reseating the CMOS battery = Still locked. After Googling for a while I found that you need to clear the NVRAM to remove the iCloud lock key. When you reach the Clover menu of your OS X Install USB, add the arguments -s and -v to the boot arguments and select the Install OS X <Version> option on the first menu. When you get to the bash prompt run nvram -c (or a few times if it makes you feel better after making the same mistake) and reboot. Your Mac should no longer be locked! Since I decided to re-install afterwards, I can't guarantee it won't re-lock if you don't re-install and keep using your existing installation, but at least you'll be able to re-use the laptop for OS X again. Learn from my stupidity. Don't play with iCloud.
  6. So, I've managed to get my Latitude E7470 working using the Catalina Clover guide, but I'm struggling to get the DW5811e / EM7455 WWAN card to work. The card shows up under System Report > Hardware > USB as "DW5811e Snapdragon X7 LTE" but nothing appears in the WWAN menu option. I've tried to edit the CellPhoneHelper.kext to add an option with Product ID 0x81B6 / 33206 and Vendor ID 0x413C / 16700 (the details I got from the above report on the USB page) but it doesn't appear to have worked (though didn't break anything either!) Would appreciate it if anyone who's got it to work or has any suggestions could give me some pointers.
