Howdy,

 

So I ran these scripts on my Mac 10.10.5
For some reason, it get a clean install, but the drivers do not show up. 

With the first script:

ls /dev/cu*

/dev/cu.Bluetooth-Incoming-Port /dev/cu.SLAB_USBtoUART

/dev/cu.Bluetooth-Modem

 

Second:

ls –n 50 /var/log/system.log

ls: 50: No such file or directory

ls: –n: No such file or directory

/var/log/system.log

 

And third:

kextutil -n /Library/Extensions/SiLabsUSBDriver.kext

/Library/Extensions/SiLabsUSBDriver.kext appears to be loadable (including linkage for on-disk libraries).

 

When I run a software report and go to USB, no such driver appeart for UART Bridge. Any suggestions? 

Hi D3D, I have the same problem, could you fix it???? Some one knows how to fix it?

In High Sierra I had to follow this guide: 

https://developer.apple.com/library/content/technotes/tn2459/_index.html#//apple_ref/doc/uid/DTS40017658

Then I needed to:

sudo kextutil -tn /Library/Extensions/SiLabsUSBDriver.kext

My Mac OS High Sierra 10.13.1

During the installation of SiLabs VCP Driver (SiLabsUSBDriverDisk.dmg) things appeared normal and successful. However, the device doesn't work (not seen by application, not shown in Mac USB device list). Please help, and appreciate any hint for next step to diagnose this problem. Here's what I 've done so far:

The kextutil command shown below:

sudo kextutil -tn /Library/Extensions/SiLabsUSBDriver.kext

/Library/Extensions/SiLabsUSBDriver.kext appears to be loadable (including linkage for on-disk libraries).

The list of cu device only show this:

ls -al /dev/cu*

crw-rw-rw-  1 root  wheel   21,   1 Nov 17 16:08 /dev/cu.Bluetooth-Incoming-Port

MacOS extention policy shows existence of SiLabs driver:

sqlite3 /var/db/SystemPolicyConfiguration/KextPolicy

SQLite version 3.19.3 2017-06-27 16:48:08

Enter ".help" for usage hints.

sqlite> SELECT * FROM kext_policy;

One of my end users is having the same issue, High Sierra, no VCP present.

Is there any solution to this? 

Facing same problem. After updating to macOS High Sierra 10.13.3 none of my SiLabs supported devices do work/connect.

Same problem.  Running High Sierra 10.13.3.  None of my SiLabs devices are recognized when connected to my Mac using the High Sierra OS.  The devices do work on the Mac when running Windows 10 via Parallels.

Facing same problem. After updating to macOS High Sierra 10.13.3 none of my SiLabs supported devices do work/connect. Is there any progress solving this issue or any known workaround ?

i tried all the stuff but doesn’t work. It works on a windows VM though! so it looks like a osx driver problem to me. Also interested in a fix or workaround!

I am happy to inform you that after changing the USB cable i am now able to connect my device via the SiLabs driver on macOS 10.13.3. I had used two Micro-USB cables from two different power packs both did not work. After using the third Micro-USB cable from a Smartphone it worked like a charm.
