You can use this command to get list of all port used and process using the port and type of network protocol codenetstat -tunlp /codeThis command will list of all listening ports If you want only a specific port.Use this codenetstat -tunlp. You’ll be shown the application name that is using your port number. Checking which port is being used by a application: This is exactly the reverse of the above steps. Open the command prompt - start » run » cmd or start » All Programs » Accessories » Command Prompt. Type tasklist findstr 'applicationname'. Replace the applicationname with the application that you want to check (for example, apache). Jul 31, 2013 Somehow I’ve only noticed now that netstat on Mac OS X cannot show the program name. Actually on Mac OS X, the -p parameter of netstat doesn’t mean program or process but protocol. Also there is no -t parameter but it can be done using -ptcp. $ netstat -an -ptcp grep LISTEN tcp4 0 0 127.0.0.1.10000. Jun 02, 2011 So, if I wanted to find out what was running on port 80: sudo lsof-i: 80 # checks port 80 COMMAND PID USER FD TYPE DEVICE SIZE / OFF NODE NAME ruby 64888 wg 6 u IPv4 0x6ddd270 0 t0 TCP.:gdsdb (LISTEN) This command shows a list of open files. The -i option checks for internet addresses with the colon symbol representing a port (instead of an actual IP address).
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.
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 adaptor 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 adaptor to connect it.
These Mac models have Thunderbolt 3 ports:
- MacBook Pro introduced in 2016 or later
- MacBook Air introduced in 2018or 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 adaptor 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 adaptor 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 until 2015
- MacBook Air introduced in 2011 until 2017
- Mac mini introduced in 2011 until 2014
- iMac introduced in 2011 until 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.
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 until 2010
- MacBook Air introduced in late 2008 until 2010
- Mac mini introduced in 2009 and 2010
- iMac introduced in 2009 and 2010
- Mac Pro introduced in 2009 until 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.
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.
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 adaptor. 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 adaptors and cables for Mac notebook computers.

Network administrators can use this information to make sure that Mac computers and other Apple devices can connect to services such as the App Store and Apple's software-update servers.
Ports used by Apple products
This is a quick-reference guide showing common examples, not a comprehensive list of ports. This guide is updated periodically with information available at the time of publication.
Some software might use different ports and services, so it can be helpful to use port-watching software when deciding how to set up firewalls or similar access-control schemes.
Some services might use more than one of these ports. For example, a VPN service can use up to four different ports. When you find a product in this list, search (Command-F) in your browser for that name, then repeat your search (Command-G) to locate all occurrences of that product.
Some firewalls allow selective configuration of UDP or TCP ports with the same number, so it's important to know the type of port you're configuring. For example, NFS can use TCP 2049, UDP 2049, or both. If your firewall doesn't allow you to specify the type of port, configuring one type of port probably configures the other.

The application firewall in macOS is not a port-based firewall. It controls access by app, instead of by port.
