	"plain_text": "Set up a computer running VNC software for Remote Desktop\r\nArchived: 2026-04-05 15:42:22 UTC\r\nVNC access is determined by the VNC software. To access a computer running VNC, you only need to know the\r\nIP address or fully qualified domain name and the password designated in the VNC software. The VNC password\r\ndoesn’t necessarily correspond to any other password on the system.\r\nSet up a non-macOS client running VNC software\r\nYou can set up a non-macOS client to be viewed with Remote Desktop.\r\n1. Install the VNC Server software and assign a VNC password on the client computer.\r\n2. Make sure the client’s firewall has the VNC port open (TCP 5900).\r\nFor more detailed instructions on steps 1–2, see the documentation that came with the client operating\r\nsystem, VNC software, and firewall software.\r\n3. Make sure “Encrypt all network data” isn’t selected in the Security pane of Remote Desktop preferences.\r\nIf you encrypt network data, you won’t be able to control the VNC client, because Remote Desktop can’t\r\nopen the necessary SSH tunnel to that computer. When you try to control a computer running VNC\r\nsoftware, you see a warning that the keystrokes aren’t encrypted.\r\n4. Add the computer to the All Computers list in Remote Desktop using the client’s IP address.\r\n5. Enter the client computer’s VNC password in the Remote Desktop authentication dialog.\r\nConfigure a client to be controlled by non-Apple VNC software\r\nYou can configure a Remote Desktop client to be controlled with non–Apple VNC software. Allowing non–Apple\r\nVNC software access to a Remote Desktop client is less secure than using Remote Desktop to control the client.\r\nThe VNC protocol implemented in non–Apple VNC software may not encrypt keystrokes sent over the network,\r\nso sensitive information can be intercepted. Also, the non–Apple VNC software expects the password to be stored\r\nin a cryptographically unsecured form and location. Granting VNC access to control a screen is the most powerful\r\nfeature in Remote Desktop, and provides nearly unrestricted access.\r\nWARNING: Don’t select a VNC password that’s the same as the password of any local user on the client\r\ncomputer or of the Remote Desktop administrator.\r\n1. On the client computer, choose Apple menu \u003e System Preferences, click Sharing, then select Remote\r\nManagement in the list at the left.\r\n2. Click Computer Settings, then select “VNC viewers may control screen with password.”\r\nhttps://support.apple.com/guide/remote-desktop/set-up-a-computer-running-vnc-software-apdbed09830/mac\r\nPage 1 of 2\n\n3. Enter a VNC password, then click OK.\r\nChange the VNC port on an existing computer\r\nAfter you add a computer running VNC software to a computer list (or when you’re first adding it), you can set a\r\ncustom port for VNC communication, and you can designate a display to control.\r\n1. In Remote Desktop , select a computer list in the sidebar of the main window, select a computer\r\nrunning VNC software, then choose File \u003e Get Info.\r\n2. Click Edit, edit the Screen Sharing Port field, then click Done.\r\nDesignate a custom VNC port when adding a computer\r\nYou can pick a custom VNC port on which to view clients. Custom VNC ports are used for Network Address\r\nTranslation (NAT) implementations, firewall settings, or viewing multiple displays.\r\n1. In Remote Desktop , choose File \u003e Add by Address, then enter the following:\r\nThe IP address or fully qualified domain name of the client computer\r\nThe user name and password\r\n2. If the client computer uses NAT, click the Advanced Options triangle.\r\n3. Enter the public ports that are mapped to the client in the Remote Management Port field and the Screen\r\nSharing Port field, then click Add.\r\nSource: https://support.apple.com/guide/remote-desktop/set-up-a-computer-running-vnc-software-apdbed09830/mac\r\nhttps://support.apple.com/guide/remote-desktop/set-up-a-computer-running-vnc-software-apdbed09830/mac\r\nPage 2 of 2",
