Unauthorized developer error when installing Sfax Driver on a Mac
If you are getting a “can't be opened because it’s from an unidentified developer” error, it may be necessary to change the Security & Privacy setting to “allow applications downloaded from anywhere”
To change, open the System Preferences. This can be done by either clicking on the System Preferences icon in the Dock or by going to Apple Menu > System Preferences.
Open the Security & Privacy pane by clicking Security & Privacy.
Make sure that the General tab is selected. Click the icon labeled Click the lock to make changes.
If prompted, enter your username and password into the prompt that appears and click Unlock.
Under the section labeled Allow applications downloaded from:, select Anywhere. On the prompt that appears, click Allow From Anywhere.
Exit System Preferences by clicking the red button in the upper left of the window. You should now be able to install applications downloaded from the internet.
Once this is done you will be able to continue in taking the steps to install the Sfax Driver.
