COM port problem on mac

Development Tools Uploading

Hello everyone,

Trying to use Arduino uno R3 on my macOS 14.0 (23A344).
Also i am using Dell DA300 adapter to connect USB.

But, after choosing Arduino AVR Board, there is no COM port to choose, only /dev/cu.BLTH.
Tried to download and instal several drivers(CH341SER_MAC, PL2303HXD_G, FTDIUSBSerialDextInstaller_1_5_0), restarting and nothing happens.

Any advice will be appreciated, thank you.

If you look in the system report (Apple/About this mac/More Info/General/System Rport/USB) do you see differences with the arduino detached and attached?

If it’s a legit UNO R3 no driver is necessary

If it isn't recognizing it in the systems report, it might have some sort of hardware problem. Does this arduino work on other machines? (With the same cable.)
