How to install driver CH340/340g CH341 for USB-TTL Arduino IDE on macOS 10.12 Sierra 16A313a

Excuse me sr . Why you erased ftdi files not only .kext and .com?

how about catalina?

rm: com.wch.*: No such file or directory
iMac-de-Lovehouse:receipts lovehouse


iMac-de-Lovehouse:Extensions lovehouse$ Is i grep usbserial.kext
-bash: Is: command not found


what happened?

Worked for a couple of hours, then some USB driver file went missing according to Arduino IDE.

What if i don't have the old driver? it is my first time to download this, will I just click the zip file then restart my laptop? will it work fine?

can this work for mac0S 10.12.6?

BE EXTREMELY CAREFUL before you fuck with your kext. I followed these instructions and could not reboot my mac - i had to completely restore my mac from backup THANKS for nothing Vitalii Tereshchuk!!!

how to fix :"the drive successfuly pre-install in advance" :((

perfect thanks

Does this stop Sierra from Crashing when CH340 is plugged in?
Cheers Benjamin

Hello Vitalii,

I have tried your recipe and it doesn't work for me. I have 10.12.3. and after removing and installing driver I still don't have /dev/cu.wchusbserial* :(

when I run it shows following message.
$ dmesg
...

Do you have any idea what could be wrong?

Do you have to remove the drivers if you haven't installed any drivers? Like if the laptop is brand new MacBook with touch bar?

Hi. After having done those steps now the mac does not leave, and it restarts again and again. Could you help me?

Problem solved! thanks for your help

Драйвер для того чтобы мак не перезагружался после подключения ардуино?

Perfect!! You solved my problems, thanks!!

Спасибо!

Thanks for your video. I am using Sierra 10.12.1. Driver installs correctly but when attaching terminal and device i see strange symbols like the speed or flow control is incorrect. Do you have solution ?
