Creating a Mac Developer Certificate

Many corporate users of the Pexip Infinity Connect desktop client produce a customized and rebranded version of the client application for their own use.

If the Mac OS X version of the application is rebranded, the repackaged application will, by default, be unsigned and will require explicit permissions to run. To allow the application to run by default, it must be signed with an Apple developer certificate.

This guide explains how to create an Apple developer certificate and how to use it to sign a rebranded Infinity Connect desktop client for Mac OS X to allow easier redistribution. See Customizing the Infinity Connect desktop client for more information.

      Your certificate will now be generated and be ready for use.

    14. Download the certificate from the list of production certificates and open it to ensure that it is added to your keychain for future use.

  3. Sign your Infinity Connect desktop client application. Open a terminal and type the following command:

    codesign --deep --force --verify --verbose --sign "Pexip AS" pathtoyour/

    Where you should replace "Pexip AS" with the Name of your certificate as shown on the Mac Certificates download page, and replace pathtoyour/ with the relevant path and application name.
