Booting Next Loader

Next Loader as the Default Boot Manager

1. When the system reboots, after a power-on or restart, first you will hear the normal chime.

2. About 3 seconds later, Next Loader is given control. If testing on a USB drive with an activity light, you will see the light flash briefly at this point.

3. About 10 seconds after that, if you have a GPU with Mac EFI, you should see the initial Next Loader boot screen. If you see nothing (a black screen), see the note below.

4. Now Next Loader will scan your system and display disk icons for all the bootable drives it finds.

5. Select an icon using the arrow keys on your keyboard, then press the return/enter key, and you should boot into the selected operating system.

Next Loader Side-By-Side with the Startup Manager

1. When the system reboots, after a power-on or restart, press and hold the option/alt key before you hear the chime.

2. The Startup Manager will appear on the screen, Now there should appear an option called "UEFI Boot Manager", which will run Next Loader.

3. If you have a GPU with Mac EFI, you should see the initial Next Loader boot screen. If you see nothing (a black screen), see the note below.

4. Now Next Loader will scan your system and display disk icons for all the bootable drives it finds.

5. Select an icon using the arrow keys on your keyboard, then press the return/enter key, and you should boot into the selected operating system.

NOTE: If you are using a Mac Pro and you do NOT have a GPU with Mac EFI, you will only see a black screen during step 3.

However, you can verify Next Loader is running about 10 seconds after the chime by pressing the Caps Lock key on your keyboard — the little LED inside the key should turn on and off. At this point Next Loader is trying to draw the boot screen, but your GPU can’t display it.

If you only have ONE drive installed (like an SSD with High Sierra), you can simply hit the return key TWICE (once for the “hit any key” screen and once to select the default boot drive), and about 15-30 seconds later the screen should wake up and show you the macOS desktop or login screen.
