 | I am currently running the latest version of macOS 11 Big Sur on my Lenovo ThinkPad T440 with a Sierra EM7345 WWAN adapter. I really, really need that WWAN adapter to work (it has a static IP address I can use to host a nice little server) It uses an Intel XMM7160 chipset, and is connected through M.2 which gets turned into USB along the way. It seems to be detected as a USB Ethernet adapter, which is almost correct (surprisingly), but no matter what combination of editing various codeless KEXTs I try, the farthest I've gotten is getting it detected as a WWAN modem stuck in "Initializing..." As far as I know, this adapter uses something called MBIM to talk to the operating system, which seems to be some sort of standard, which even seems supported by macOS, but I couldn't find any more info. In all my searches I've only seen pleas by other people trying to get this work, no one has solved this issue to my knowledge, which is disappointing. Here's what macOS can say about it: I can add that this modem (at least under Windows) is detected as 4 devices in Device Manager, the modem itself, its GNSS sensor, its AT command port, and its Trace port (whatever that means). I can also access the AT command port from within macOS, which doesn't help connecting it to the internet, I've tried that. Please, someone, help me with that wretched beast. Edit for clarity: I'm using the OpenCore bootloader. [link] [comments] |
