Developing with macOS

#1

Hi, is there any solution to use mangoh devices with MacOS 10.15 or greater? Apple dropped support for other than 64bit drivers over a year ago and since then it has not been possible to develop with mangoh/legato. I have tried to use VM also but no luck in there. Everything works great with earlier macOS-version.

Hi Elmo,
I’m on MacOS 10.15 too. I’m using a Linux VM since 10.15 for the reason you highlighted.
It should work fine with any Linux VM as long as you take care to fix the network interface that sometimes goes up and down for some reason:

Hi, thanks for the answer. My VM seems to not recognize device at all.

this is my ifconfig output:

mangoh@mangoh-vm:~$ ifconfig

Host machine recognizes wp7702 as an usb device but not as a network device.

what is the return of the following?
AT!ENTERCND=“A710”
AT!USBCOMP?
AT!USBCOMP=?

Also please capture the “dmesg” messgae.

This is my dimes log after I plug in the device:

You need to use

sudo ifconfig enp0s11u1i19 up
sudo ifconfig enp0s11u1i19 192.168.2.3

Awesome, thanks!
