Steps

  1. Quit AutoCAD completely, then restart the Mac. Open AutoCAD again and see if the error is gone.
  2. If the error comes back, look for a How do I fix this button or link in the error message and click it. It opens the Autodesk page for error 3004.
  3. From that page, download the latest Autodesk Identity Manager update and install it. Enter your Mac password when asked.
  4. Open AutoCAD again and sign in with your Autodesk account. Then open a drawing to confirm it works.
  5. If part of the drawing window stays gray, drag the window edge or toggle full screen with the green button at the top left of the window.
  6. Still stuck? In the AutoCAD menu, choose sign out, quit, reopen, and sign in again.

Common questions

Did the Mac update break my AutoCAD license?

Usually not. The license is fine. The sign-in component needs an update to work with the new macOS.

Will I lose my drawings?

No. Your drawing files stay on your Mac. Only the sign-in step is failing.
