What is Verbose Mode on Mac
Verbose Mode is a booting mode on Macintosh computers that replaces the graphical startup screen with a series of command lines. Those specified command lines display what Mac is doing and what drivers and software it is loading upon startup or in programming.
Verbose Mode can help you recognize various Mac problems you may be experiencing with macOS like Mac white screen problem, or third-party applications. To quickly find what your exact problem is, you need to read those technical texts word by word and understand their meaning.
Usually, the messages that appear on the screen along with the words "error", "failed", or "terminated" locates where the problem is. And please be noted that, unlike Mac Recovery Mode, Verbose Mode only helps you verify the problem, it is incapable of troubleshooting your issue.
Furthermore, since the command lines displayed are complicated technical texts, only advanced users who are familiar with Unix or computer geeks can understand them. Common users may find it so hard to figure out.
How do you enable Mac Verbose Mode
To start up your Mac in Verbose Mode, follow these simple steps:
- If your Mac is on, turn it off first.
- Press the Power button to start your Mac.
- As soon as your Mac starts to boot, press and hold the Command + V key combinations.
When a series of command lines show up on the screen, it indicates you've successfully entered Verbose Mode. Your Mac will automatically exit Verbose Mode when its startup process completes and the macOS login screen or desktop shall appear.
Note: If you had set a Mac firmware password before, then you need to input the firmware password before loading Mac Verbose Mode.
