Secure Kernel Extension Loading (SKEL) on Macintosh Mac OS X 10.13+ Prevents Maple from Installing

Starting with Mac OS X 10.13 High Sierra, Macintosh machines will prevent the loading of third-party kernel extensions. This Secure Kernel Extension Loading (SKEL) can prevent Maple from installing, requiring manual verification in order to proceed.

1. First, navigate here:

   Apple icon > "System Preferences" > "Security & Privacy"

2. Click the "closed padlock" beside "Click the lock to make changes."

3. Press "Allow".

4. Press the "open padlock" beside "Click the lock to prevent further changes."

The installation of Maple should now proceed unimpeded.

Notes:

• Pressing "Allow" over a remote or virtual connection won't work.

• The "Allow" option is only available for 30 minutes. If you have gone past this limit, you will need to re-trigger the message by re-starting the installation.
