While entering the serial port name into the code in arduino IDE, enter the whole port address i.e: /dev/cu.usbmodem. or /dev/cu.UG-. where the. is the port number. And for the port number in case of mac just open terminal and type. Ls /dev/. and then search for the port that u have set in arduino IDE.
Information about these and other types of Mac ports is in the specifications for your Mac: Choose Apple menu > About This Mac, click Support, then click Specifications. Or check your Mac user guide.
Serial port emulators are available for many operating systems including MacOS, Linux, NetBSD and other Unix-like operating systems, and various mobile and desktop versions of Microsoft Windows. Bluetooth implements virtual serial ports over the Serial Port Profile. This is the standard way of receiving data from Bluetooth-equipped. Serial Tools for OS X, includes a Terminal Emulator, a Protocol Analyzer, and a serial port monitor to watch for connections and removals of serial ports. Serial Tools is completely free, and available from the Mac App Store. Serial Port Monitor is a professional software application that allows reading and recording serial data going through your computer’s serial ports. The program is a big help for those who develop and debug software and hardware solutions that use COM ports for serial data transfer. In Arduino, when I try and select a port to connect the ESP32 the port isn't listed. The cable works with an Arduino Uno and a Western Digital USB drive so definitely has the capability to deliver power and data. If I go to About This Mac System Report Extensions I can see the driver listed but it says not loaded: SiLabsUSBDriver: Version.
Thunderbolt 3
Use Thunderbolt 3 with displays and other devices that connect using either a Thunderbolt 3 cable or USB-C cable. You can also connect a USB-C power adapter and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adapter to connect it.
These Mac models have Thunderbolt 3 ports:
- MacBook Pro introduced in 2016 or later
- MacBook Air introduced in 2018 or later
- iMac introduced in 2017 or later
- iMac Pro (all models)
- Mac mini introduced in 2018
- Mac Pro introduced in 2019
If your Mac notebook or desktop computer has more than one port like this, each port supports ThunderBolt 3 and USB-C.
USB-C
Use USB-C with displays and other devices that connect using a USB-C cable. You can also connect a USB-C power adapter and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adapter to connect it.
MacBook models introduced in 2015 or later have a single USB-C port. This port doesn't support Thunderbolt devices.
If your Mac has only one port like this, it's a MacBook that supports USB-C but not Thunderbolt.
Thunderbolt
Use Thunderbolt or Thunderbolt 2 with displays and other devices that connect using a Thunderbolt cable.
These Mac models have Thunderbolt or Thunderbolt 2 ports:
- MacBook Pro introduced in 2011 through 2015
- MacBook Air introduced in 2011 through 2017
- Mac mini introduced in 2011 through 2014
- iMac introduced in 2011 through 2015
- Mac Pro introduced in 2013
Thunderbolt and Thunderbolt 2 are not the same as Mini DisplayPort . They have the same shape, but use different symbols on the cable and port. However, this port does support Mini DisplayPort for video output, so you can use a Mini DisplayPort cable to connect a Mini DisplayPort display.
Mac Os Serial Port
Mini DisplayPort
Use Mini DisplayPort with displays that connect using a Mini DisplayPort cable.
These Mac models have Mini DisplayPort:
- MacBook Pro introduced in late 2008 through 2010
- MacBook Air introduced in late 2008 through 2010
- Mac mini introduced in 2009 and 2010
- iMac introduced in 2009 and 2010
- Mac Pro introduced in 2009 through 2012
Mini DisplayPort is not the same as Thunderbolt or Thunderbolt 2 . They have the same shape, but use different symbols on the cable and port.
USB-A
Use USB-A with devices that connect using a USB cable. USB ports are sometimes known by the USB specification of the port, such as USB 2 or USB 3.
Mac Os Serial Terminal
Left to right: power, two Thunderbolt, USB-A, and Audio-Out.
HDMI
Use HDMI with displays and TVs that connect using an HDMI cable.
Ethernet
Use Ethernet with networks and devices that connect using an Ethernet (RJ45) cable.
Macos Serial Port App
FireWire
Use FireWire with devices that connect using a FireWire 400 or FireWire 800 cable.
SD card
Use the SD card slot with SD, SDHC, SDXC, MMC, and UHS-II media cards, such as those used by digital cameras.
Audio
Use Audio-Out — or — with headphones, speakers, and other audio-output devices that connect using an audio cable that has a 3.5 mm (1/8 inch) audio jack.
Use Audio-In with a microphone or other audio-input device that connects using an audio cable that has a 3.5 mm (1/8 inch) audio jack.
Power
Use the power port , if available, to connect your computer to AC power using a MagSafe cable or adapter. This port isn't available on newer Mac notebook computers, which use Thunderbolt 3 or USB-C for power and charging. Learn more about power adapters and cables for Mac notebook computers.

Virtual Serial Port For Mac
I bought a USB Serial port that had MAC drivers. Check before you buy it that it has drivers. Not all USB Serial have MAC support. I assume that you have installed the correct drivers from here.
First, open Terminal (Applications/Utilities/Terminal). Next, type
ls /dev/tty.*
Serial Port For Macbook Pro
to get a list of your serial lines. Pick the one that you want to open. For example, my list looks like this:
gf:dev gf$ ls -al tty.*
crw-rw-rw- 1 root wheel 18, 4 Jan 25 07:32 tty.Bluetooth-Modem
crw-rw-rw- 1 root wheel 18, 8 Jan 25 07:32 tty.Bluetooth-PDA-Sync
crw-rw-rw- 1 root wheel 18, 10 Jan 25 09:20 tty.PL2303-0000103D
crw-rw-rw- 1 root wheel 18, 0 Jan 25 07:32 tty.SerialPort-1
gf:dev gf$
And I know /dev/tty.PL2303-0000103D is the USB-to-serial adaptor becuase it’s connected, if you unplug it the tty.PL2303-0000103D stops being listed.
Knowing the serial port, you can just type screen portname datarate to show the serial data on the screen. In my case, it was:
screen /dev/tty.PL2303-0000103D 9600
To quit the screen app, type control-A, then control-.
Postscript
I don’t think that this is very complete, but it worked for me and might help you to get your USB serial working. Please let me know if there anything I can add to complete this piece.
Update 2008/12/28: A reader has pointed out this article is based on a similar article at†http://www.tigoe.net/pcomp/resources/archives/avr/000749.shtml. I must have copied some of the text and then mistakenly believed it was my own. Apologies for this mistake.
