How can I connect an arduino uno to my 2010 mac pro running macos mojave? I can't seem to make it show up on the arduino app. Thank you!
Is it an official arduino or faithful clone, or is it a clone with a different serial adapter?
Look at the black chip near the USB port - it will say either mega16u2, cp2102, or CH340G.
Official / faithful clones use 16u2 (unfortunately, this chip also has a tendency to fail when you even think about abusing the power rails). Other clones use CP2102 or CH340G. Note that clones that don't use 16u2 will show a generic port name; I think ones with 16u2 show the name of the board in parenthesis (they do on windows at least) - this is not an issue.
I'll refrain from giving further advice - I only know windows/linux. I can't even keep which name corresponds to what version of mac os.
It is kuman on one side and miroad on the other so im not sure which one is the brand. The chip is mega12u2. Thanks for the reply!

We don't care about the brand - there are scores of random brands of clone arduinos on the market, and new brands come and old ones go all the time. The markings on the chip itself are what matters.
And - you misread the tiny grey-on-black text - it's a mega16u2 (there's no 12u2); so the official drivers ought to be working.
Make sure the USB cable is completely plugged in to both the Uno and the PC.
You may have a damaged/defective or charge-only USB cable. Try a different cable.
Sometimes USB 3 ports can cause problems. Try a USB 2.0 port or a USB 2.0 hub plugged into a USB 3 port.
There does seem to be some bad luck going with Mojave and drivers, especially the CH340 but I seen some things that make me think it might extend to the ATmega16U2 as well. Hopefully it will be one of the above easy fixes though. I don't have any experience with Mac.
