-Depending on your security settings, you might need to use the Startup
-Security Utility before using the Boot Disk (see below).
-
-=== https://support.apple.com/en-us/HT208198[Startup Security Utility]
-
-With newer hardware, you should be running with the Apple T2 Security Chip (found via  → About This
-Mac → Overview → System Report → Controller). In order to boot your machine using the Boot Disk,
-you’ll need to _temporarily_ disable the default security settings as follows:
-
-* Turn on or restart your Mac, then press and hold `COMMAND + R` immediately after seeing the Apple
-  logo.
-* Select Utilities → Startup Security Utility from the main menu.
-* Click _Turn Off Firmware Password_.
-* Select _Secure Boot: No Security_.
-* Select _External Boot: Allow booting from external media_.
-* Quit the utility and restart the machine.
-
-You’ll now be able to boot your system with the Boot Disk (see above).
-
-After the new operating system has been installed via the Boot Disk, _ensure you return to the
-Startup Security Utility and re-enable the following settings_:
-
-* Click _Turn On Firmware Password_.
-* Select _Secure Boot: Full Security_.
-* Select _External Boot: Disallow booting from external or removable media_.

 == Troubleshooting
 
+* When using link:https://pi-hole.net[Pi-hole], you might need to temporarily disable prior to
+  upgrading as you might experience various errors with Apple not being able to detect an internet
+  connection which prevents the installer from working.
+* When using the boot disk and the installer fails in some catestrophic manner, reboot the machine
+  into recovery mode -- `POWER` (Silicon) or `COMMAND + R` (Intel) buttons -- to download and
+  install the last operating system used. Alternatively, you can also use `COMMAND + OPTION + R`
+  (Intel) to attemp to download the latest operating system.
 * When using the boot disk, you might experience a situation where you see a black screen with a
   white circle and diagonal line running through it. This means macOS lost or can’t find the boot
   disk for some reason. To correct this, shut down and boot up the system again while holding down
-  the `OPTION+COMMAND+R+P` keys simultaneously. You might want to wait for the system boot sound to
-  happen a few times before releasing the keys. This will clear the system NVRAM/PRAM. At this point
-  you can shut down and restart the system following the boot disk instructions (the boot disk will
-  be recognized now).
-* Sometimes, when installing XCode development tools (i.e. the `t` option), not all of the macOS
-  headers will be installed. This can cause issues with compiling and building native packages. For
-  example: `fatal error: 'stdio.h' file not found`. This can happen due to an intermittent bug with
-  the XCode installer. To fix this, you’ll need to install this package:
-  `/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg`. Depending on
-  your system, the version might differ, so look for a `*.pkg` in the
-  `/Library/Developer/CommandLineTools/Packages` folder.
