Disk Utility is a Mac storage manager that allows users to manage partitions, erase or repair the startup disk, add new hard drives, and troubleshoot issues like a USB flash drive not showing up on Mac.
To boot Mac into Disk Utility/Recovery Mode, you can either press and hold the power button on your Mac until the login window appears, then click the gear icon in the top right corner and select Restart from the dropdown menu, or press and hold the Command (⌘) + R keys as soon as your Mac starts up. This will open the Disk Utility/Recovery Mode window, where you can access various tools to manage and maintain your Mac's storage.
When you encounter disk issues, it's lucky that your Mac can still start normally, but sometimes you may be sadly found it's not possible to boot up your Mac. In such cases, we have two methods to boot Mac into Disk Utility, which can help you troubleshoot and resolve the issues.
When your Mac can start up normally, open Disk Utility using Spotlight or the Finder to access it.
Step 1. Open the Finder on Mac.
Step 2. Go to the Applications menu, and click "Utilities".
Step 3. Scroll down, and you will find the Disk Utility.
If your Mac is stuck on the Apple logo or fails to boot, trying to start it up with specific keys may help resolve the issue. The startup keys differ between Apple silicon Macs and Intel-based Macs, so it's essential to know which ones to use. By booting your Mac into Disk Utility using the correct startup keys, you may be able to troubleshoot and fix the problem.
For Apple Silicon Mac:
Step 1. To enter Recovery Mode on your Mac, make sure it is shut down, then hold the power button until the Recovery Mode screen appears on the screen.
Step 2. To access the Disk Utility on your Mac, you can click on the "Disk Utility" option from the Utilities folder in the Applications folder. This will open the Disk Utility window, where you can select the drive you want to erase and start the process of formatting your Mac's startup disk. Once you've selected the drive, you can follow the on-screen instructions to complete the erase and format process.
For Intel-based Mac:
Step 1. To enter Recovery Mode, shut down your Mac, then hold down the Command and R keys simultaneously. Release them when you see the Apple logo and the spinning globe, indicating that your Mac has entered Recovery Mode.
Step 2. To access Disk Utility on your Mac, click on it, and your computer will successfully enter the Disk Utility.
If your Mac won't boot into Recovery Mode or won't boot at all, try booting in safe mode by holding the Shift key while turning it on. If that works, try booting normally again. If that doesn't work, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU) by turning off your Mac, unplugging the power cord, pressing the power button for 20 seconds, and plugging the power cord back in.
