Hello! I’m really new to Arduino and I have the Elegoo UNO R3 and apparently I need to match the board: Arduino UNO to a port related to some COM.. or with the name arduino in it, it’s not that I’m not getting any ports I’m just unsure on which one I’m meant to use because the option I’m getting isn’t related to what I’m « supposed to use so if someone could please help on which one I’m meant to be using it would be greatly appreciated !!
Looks like you are on a Mac but none of those ports match the UNO board. Which UART chip (near the USB connector) does your Elegoo board have, the 16U2 (square) or the CH340 (two rows of pins)?
You may need to install the driver.
BTW, just in case, have you tried another USB cable?
I think the FTDI driver is most likely and it can be found here:

The CH340 driver is here should you need it:

From the photo your board has the 16u2 chip so you will want the FTDI driver link that I just added to my previous post.
Did this come with one of those starter kits? If so, there should be a document on the CD that came with it.
Yes, it did and thank you so much for your help 
, I’ll try the drive but it did come with the starter kit and I did follow up on it yet the options just don’t show up, I don’t think I was meant to download anything apart from the actual arduino application itself ..
On the root directory of the CD there is a UNO R3 Driver.pdf document which has a section for the Mac. On Windows, the driver installs automatically, but for the Mac, the section provides the link for the driver and also instructions to install it so it does seem that this is a necessary step for the Mac. This document is separate from the Starter Kit guide that discusses the installation of the Arduino IDE. The document looks like it hasn't been updated in a long time so its possible things may have changed since it was written.
if it's a standard 16u2 board, no driver is necessary.
Installing stuff from random places on the internet is not safe.
Which Mac do you have ? Did you try to connect the USB directly to the Mac?
FTDI drivers are for FTDI ICs. The 16U2 is IC from Atmel.
There is only one official Arduino board with a FTDI serial-to-usb converter and that is the classic Nano.
The Elegoo information is so out of date that its likely that a modern Mac
can nowadays auto-detect and install the correct driver.
I provided the link that was given in the board manufacturers (Elegoo) instructions, which actually points to the FTDI download page, so this wasn't just from anywhere. However, I absolutely do agree with your statement. I perhaps need to consider how to approach this in the future.
Yes, this is correct. My understanding also is that the 16U2 is not a UART, but but a microcontroller that emulates (under licence) the functions of an FTDI chip. This is why downloading an FTDI driver didn't seem out of place to me.
However, I also realized after I posted that the instructions provided by Elegoo are so out of date and things may have moved on so that the information is no longer accurate and may even be misleading. If so, then I apologize to the OP for any confusion.
sorry, my comment was in general, not specifically direct to what you shared.
