Arduino not communicating with Mac (El Capitan)

My arduino uno R3 stopped working so I tried some troubleshooting and found out I didn't had to reinstall my bootloader. It wasnt working so I removed my ATmega328 chip and put a new one in. The bootloader installed on that one (using my Elegoo uno clone). Since I installed the bootloader, the rechipped Arduino has been unable to communicate with my computer and doesn't show up on the system information usb ports page, terminal, or anything. My Elegoo clone does show up however and I've downloading both FTDI drivers and CH34 drivers and still nothing. Chord works fine and I'm just at a loss for what to try next. Any suggestions would be greatly appreciated.

Thanks :slight_smile:

The pictures are of the terminal window running the 'system_profiler SPUSBDataType' command. The one with "communication device" is with the Elegee clone plugged in and the one without is with the Arduino plugged in

No need to spam the forum.
Your other post about the same topic is still there.

My bad I'm still getting familiar with how to ask for help on here

You mention drivers for the CH340 and FTDI chips but you never say which USB to serial chip your R3 board has installed. Is it genuine Arduino? If so, neither driver is correct.

Rather than flailing about with drivers that are not required, how about we determine the correct driver to install? Heck, you will usually make matters worse by trying to install FTDI drivers - because your version of OSX already had them installed.

So, please, a link to your clone if it isn't a genuine Uno R3.
