Copy-paste and sound not working from Windows Remote Desktop to a Mac? Check four switches

#macos #windows #productivity #tutorial

Remote Desktop from Windows to a Mac works, but paste does nothing and the Mac is silent.

You copy a line of text in mstsc.exe, paste it on the other side, and nothing arrives. Or a video plays on the Mac and the Windows PC hears nothing.

The usual cause: clipboard and sound each have two switches, one on each side, and both are read only when the session starts. Here is where they are and the order we check them in.

What crosses the connection (and what doesn't)

We build the Mac side of this setup (disclosure at the end), so these are the limits of our app, RDPyon 1.0.3, checked in November 2026:

  • Clipboard: text, images and files, both directions, over the normal RDP clipboard channel.
  • Sound: one way only. The Mac's audio plays on the Windows PC. Using the Windows microphone on the Mac is not supported yet.
  • Sound needs macOS 13 or later on the Mac.
  • After changing a setting on either side, disconnect and connect again before you test.

Windows side: two boxes in mstsc

  1. Open Remote Desktop Connection and press Show Options.
  2. Go to the Local Resources tab.
  3. Under Remote audio, press Settings and choose Play on this computer.
  4. Under Local devices and resources, tick Clipboard.
  5. Back on the General tab, press Save so the choices stick, then connect.

If a session was already open when you changed these, close it and open it again. mstsc does not apply them to a running session.

Mac side: two menu items

RDPyon menu on a Mac, Preferences submenu open: Clipboard Sync (text) is ticked, Forward Mac Audio is not
This Mac has the clipboard on and audio forwarding off, which is exactly the "no sound" case.

In the menu bar app, open Preferences and look for a tick next to:

  • Clipboard Sync (text): despite the label, images and files use the same switch. Off means nothing crosses.
  • Forward Mac Audio: greyed out on macOS 12 and older.

Both are on by default, but check the tick rather than assume.

If paste still does nothing

  1. mstsc → Local Resources → Clipboard ticked? Reconnect.
  2. Mac → Clipboard Sync ticked? Reconnect (it is applied when a session starts).
  3. Copy again on the Mac and open the menu. It shows the last clipboard transfer, so you can tell whether the Mac handed the data over at all. If it says the transfer failed, copy once more.

If there is no sound

  1. Windows first: Remote audio = Play on this computer, and the Windows volume and output device are on. The volume you hear is the Windows PC's, so turning up the Mac does nothing.
  2. Mac: Forward Mac Audio ticked, macOS 13 or later. Reconnect, then actually play something. Silence while the Mac is idle is expected.

Disclosure

We make RDPyon, a small Mac app that lets the built-in Windows mstsc connect to a Mac over RDP, with no account or relay server of its own. It's a paid app: as of November 2026 a one-time $19 purchase, with a 14-day free trial. The steps above for mstsc are the same whatever the Mac side is; the Mac menu items are ours.

If you hit a clipboard or sound case this list doesn't cover, tell us what you copied and which macOS version. That is how the list grew.
