  1. A few of us with old C2D/C2Q platforms (mostly desktop) experienced CMOS reset since updating to 10.15.4. During troubleshooting, the issue was pinpointed to 10.15.4's new boot.efi file (located in /S/L/CoreServices) which, as many of us noticed, was displaying some new info when booting in verbose mode. Initially, replacing 10.15.4's boot.efi file with that of an earlier Catalina release or even an earlier macOS version was found to get rid of the problem without adverse affect on booting Catalina 10.15.4. However, this only worked for Hackintosh systems running Clover, not for systems running OpenCore. 10.15.3_boot.efi.zip File ownership needs to be re-adjusted to root:wheel upon replacement: sudo chown 0:0 /S*/L*/CoreServices/boot.efi Update: 15 April 2020 - - - - - - - - - - - - - - - Following further troubleshooting with vit9696, telepati and a few others, vit9696 worked out a temporary workaround for OpenCore in the form of a 5-bytes NVRAM variable wake-failure set to 00 00 00 00 00. All details and explanations are available here. For Clover users, this workaround alternative to replacing boot.efi can implemented as follows in Terminal: sudo nvram wake-failure=%00%00%00%00%00 Of course, this needs NVRAM to be working properly on the target Hack. For Hacks with no natively-supported NVRAM, it is required to install EMUVariableUEFI.efi Clover module + RC scripts on the Catalina boot volume. Once the variable is set and the system rebooted to take it into account, no more CMOS reset on rebooting from 10.15.4.

  2. USB port issue. Unable to check your EFI file, not downloadable. I have a bootpack somewhere for E6440 with the kext USBPort.kext Ahh, here it is

  3. 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.

  4. Have got one in there but still doesn't populate in the Network PrefPane.

  5. 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>

  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.
