Plugin won't load in Premiere
Sandboxing, extensions reload, connection. The fix tree for the most common install failure.
The MOVON panel installs as a UXP extension and talks to MOVON's servers to run the match. When the panel does not show up in Premiere, one of three things is in the way: macOS sandboxing, a Premiere extensions reload, or the connection to MOVON.
Confirm the panel is supposed to be there
In Premiere, open Window → Extensions. If "MOVON Match" is listed but greyed out, the install completed and Premiere is not loading it. If it is missing entirely, the install did not register the extension. Different fixes, both below.
1. macOS sandbox blocked the install
The most common cause on a fresh install.
- Open System Settings → Privacy & Security.
- Scroll to Security. If a "MOVON Match was blocked" line is there, click Open Anyway.
- Quit Premiere, then run the installer again.
If the installer was downloaded with a browser other than Safari, the quarantine flag can stick. The installer says so clearly. The fix is the same.
2. Premiere did not reload the extensions list
Extensions register at Premiere launch. If MOVON installed while Premiere was open, Premiere will not see it until the next launch.
- Quit Premiere completely (Cmd+Q, not just closing the window).
- Open Premiere again.
- Check Window → Extensions.
If the panel is now listed but still not opening, go to step 3.
3. The panel cannot reach MOVON
The match runs on MOVON's servers, so the panel needs an internet connection and a signed-in account. If the connection is down, the panel loads but reports a connection error on Match.
- Check the connection dot in the panel. Grey or red means it cannot reach MOVON.
- Confirm the Mac is online and the panel is signed in.
- A firewall, VPN, or strict proxy can block the outbound connection. Allow MOVON, or pause the VPN and retry.
The panel loads even with no connection, so a panel that opens but cannot Match is almost always a connection or sign-in problem.
Reset Premiere's extension cache
Still refusing to load? Premiere's preferences may hold a stale cache.
- Quit Premiere.
- Hold Option + Shift while opening Premiere. Confirm the reset dialog.
- Check Window → Extensions again.
This resets other Premiere preferences too, so it is the last resort.
