What is DFU Mode?
DFU mode is a rudimentary state for iOS and iPadOS devices, as well as Macs, where the device’s firmware can be updated or restored without the need for the operating system to be loaded. It’s a powerful tool for resolving software issues, but it’s also important to understand the risks. Entering DFU mode can erase all data on your Mac, so make sure you have a backup before proceeding.
Why Use DFU Mode?
DFU mode is a last resort for fixing stubborn Mac problems. Here are some common scenarios where you might need to use it:
- Stuck on a black screen: If your MacBook Pro is stuck on a black screen, DFU mode can help you restart the system and potentially recover lost data.
