M5Paper on macos Big Sur
-
I have followed the instructions. As I can see the driver is installed :
❯ ls -ld /Library/Extensions/Si*
drwxr-xr-x 3 root wheel 96 3 Nov 2016 /Library/Extensions/SiLabsUSBDriver.kextThe application is in the applications folder as well :
Factory test on the device looks good
I have also tried uninstalling the driver. Reinstalling and rebooting.
Any other suggestions ?

I suppose the drive isn't loading, so I tried to load it on the cli :sudo kextload /Library/Extensions/SiLabsUSBDriver.kext

Ok, I have found that there is currently an issue in OSX in that the driver is randomly not being loaded for the adapters.
As typical Apple have broke something. -

It consistently fails to load, not randomly. At least that's the case for me.
What's your source?@m5stack Can you confirm is this was tested on Big Sur 11.4 ?
Unless someone can confirm they have has it working on that specific version it's more than likely the driver was not built for this OS.There are over 550 kernel extensions on my mac and they all work perfectly. It seems the interface Apple exposes for loading extensions works for everyone else.

@m5stack
For general information Silicon Labs has a newer version of the driver which I can load.
But that does not work either :(https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

Was working on 10.14 but 10.15 fails.
-
I'm on 11.14 Big Sur
10.14 would be Mojave released in 2018
@m5stack
At this point I can only assume recent macos is not supported and I'll and get my hands on a windows computer :-( -
@nigel Im on Catalina (just upgraded from Mojave) and now have the issues :(

hello I got the exact same issue with my mac book pro, I will add some more details, I am using the default apple mac https://www.apple.com/shop/product/MUF82AM/A/usb-c-digital-av-multiport-adapter and then the Burner app, it does display the same option ttyusbmodem something. It would be great to find a workaround to be able to updgrade the firmware and start innovating ;)

I found an issue with the driver and had to select the kext file and now the driver works and usb serial is now working again!

Hi @ajb2k3 what do you mean by selecting the ktext file, something like
sudo kextload SiLabsUSBDriver.kext
me it does not change anything, I am on OS Catalina

Select? wow autocorrect!
Nope, It should read delete.
OSX has another driver that is conflicting with the slabs driver. -
I will try to do so deleting it
-
@ajb2k3, what .kext did you delete? I can see that there is a conflicting driver but I can't figure out which one.
