There’s a discussion in this GitHub issue about it. Some people use a virtual Windows or Linux machine. There’s also a link to a driver. But they mainly talk about macOS Big Sur. So I’m not sure it works with High Sierra.

Orderderd a replacement for my SIM800 1.4 with CP2104 and got a new one with CH9… 102F which fails to upload with the following error Message in PlatformIO on macOS 11.3.1 (OSX)
```
Serial port /dev/cu.usbmodem52780006671
Connecting....
Chip is ESP32-D0WD (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: 3c:71:bf:xx:xx:xx
Uploading stub...
A fatal error occurred: Failed to write to target RAM (result was 01070000)
*** [upload] Error 2_
```
The only difference I could spot between my old and the two new boards is the CH9102F Chip.
Any ideas, how to solve this issue?
