Mac OS Prevents TreeAge Pro from Running

Recent changes to Apple's Mac Operating System (OSX) have made it more difficult to install TreeAge Pro. We apologize for the inconvenience.

Apple recently restricted the options in System Preferences > Security & Privacy > General to allow installation of software only from the App Store and from identified developers. We had been an identified developer for several years, but Apple has made signing our installers impossible.

This issue may occur in a few ways - from most likely to least likely below.

Use the option to run TreeAge Pro anyway.

  1. Open System Preferences.
  2. Click on Security & Privacy.
  3. Select the General tab.
  4. If you see a message to allow TreeAge Pro to run anyway, click the appropriate button.

Change the option to allow installation of any software with the following instructions.

  1. Open System Preferences.
  2. Click on Security & Privacy.
  3. Select the General tab.
  4. Select the "Allow apps downloaded from" option "Anywhere".

You should then be able to install and run TreeAge Pro on your Mac.

I don't see the "Anywhere" option above.

If you do not see the "Anywhere" option within System Preferences > Security & Privacy > General, please follow these instructions to reactivate the option.

  1. Open Finder.
  2. Navigate to Applications > Utilities.
  3. Double-click on the application Terminal. You will see a console open where commands can be entered. The prompt will look something like this...
  4. Type in the following command.
    sudo spctl --master-disable
  5. Press Enter to submit the command.
  6. Enter your administrator password when prompted.
  7. Return to the prior instructions above.
