Authorization: Max 4.6 (or older)


You can authorize with Challenge/Response or iLok. If you do not own all three products, just skip instructions specific to the product you do not own.

Challenge/Response Authorization

  1. If you haven’t already installed Max/MSP/Jitter, please do so before proceeding.
  2. Launch Max/MSP. You’ll see a dialog box asking you to Authorize Max/MSP.
    2a. Jitter Owners
    – Mac: If Max/MSP is already authorized, then hold down the “Control-Command” keys while starting up the application (not from the dock). Note: If you are still running Jitter 1.5, then throw away the “J-offer-15-osx” (located in the Preferences folder of the Library folder inside your home directory) before starting up the application.
    – Windows: If Max/MSP is already authorized, start MaxMSPJitter while holding down “Shift-Control-C”.
  3. Click the Authorize button.
  4. UNcheck “use my iLok smart key” and click next.
  5. You’ll then see a dialog box with a string of short words called a Challenge.
  6. Copy the Challenge.
  7. Paste it into the Challenge/Response Authorization Form, fill out the rest of the form, and submit it.
  8. After processing your authorization, we will e-mail you a new string of short words called a Response.
  9. Launch Max/MSP again, click Authorize, and enter the Response in the dialog box below the Challenge string. Your software will then be permanently authorized on your hard disk.

Important Notes

  • If your computer becomes deauthorized, the same Response may reauthorize it, even if the Challenge has changed. Please keep a record of your Response.
  • If you have any problems with your authorization, please contact technical support.
  • We will respond to two Challenge/Response requests. If you need additional authorizations, please include an explanation in the Comments field on the Challenge/Response Authorization Form.
  • If you only need to authorize a computer temporarily, please use the Comments field to tell us the date you would like it to expire.

iLok Authorization

  1. Review the iLok FAQ.
  2. Go to the iLok Authorization Form.
  3. Enter the required iLok information.
  4. As soon as your iLok account has been verified, an asset will be deposited, and you will be notified.

Important Notes

  • If you do not own an iLok and would like more information, please visit the iLok website.
