Mac start in Verbose Mode - if the Mac no longer boots properly ...

If you want to start the Apple Mac in verbose mode, you will find the right instructions here. In this boot mode, you can display the individual processes when starting the Apple computer as command lines. This is useful if there are problems starting the computer, the machine does not start up correctly and/or the start-up process is interrupted at a certain point. Of course, the procedure for independent troubleshooting also works on the iMac or MacBook. I also have one for you below Port-Trick listed as an extra ;)

Here you will find the instructions with the keyboard shortcut for Mac boot in Verbose Mode. This shows you all start processes, operations and apps as a text log.

Mac boot in Verbose mode for an encrypted macOS start

The boot, the so-called startup of the Mac, can be disrupted by various circumstances. Newly installed software, damage to the hardware, any hiccups in the system and so on can be the cause. To use the Verbose mode when starting the Apple computer, you proceed as follows:

  1. Turn off Apple Mac (if not already turned off)
  2. Turn on the Apple Mac and press cmd + V
  3. Hold down cmd + V until the command line appears
  4. Release the buttons and follow the text on the screen
  5. If the booting should stall or stop at one point, you can see what is causing the problem

What does verbose actually mean?

Boot mode, which you can force using the command key and the V key, is called "verbose" because this adjective means something like "verbose", "detailed" or "verbose". And that fits very well, because every small operation and process is shown as text information during the start-up process. So if a certain software blocks the normal start of macOS, this can be read directly from the screen. However, if you don't always want to do this using the mode described, but want to output a boot log as a text file, then that works too.

Terminal command: Output the start protocol as a .TXT file

There are a few more tricks to tracking booting. If macOS starts normally and the system can be used without any problems, you can activate a useful function using the terminal, for example. To do this, call up the Terminal (via the Utilities folder, the Launchpad, the Spotlight search or similar) and then enter the following command:

sudo dmesg >> ~ / Desktop / kernlog.txt

Confirm the command with the Enter key and after every system start you will receive a text file on your desk in which the start of the computer is documented in Verbose style. If you are used to reading the text, you may notice errors or a suspicious app. You can then use this as information to correct the errors and to bring the startup of the Mac back to normal.
