Free Up Space on Your MacBook: Removing macOS Beta Partitions

Running low on disk space after installing a macOS beta? Reclaiming that space is easier than you think. Removing the partition not only frees up storage but can also improve your Mac's performance. This guide provides two methods to remove a hard drive partition on your Mac.

Method 1: Using Disk Utility

This straightforward method uses macOS's built-in Disk Utility.

Access Disk Utility: Open Spotlight search (Command Space), type "Disk Utility," and select it.
Select the Target Disk: In Disk Utility's sidebar, choose the disk containing the partition you want to remove.
Delete the Partition: Click the "Partition" tab. Select the partition in the pie chart and click the minus (-) button below.
Apply Changes: Click "Apply" and confirm the partition changes in the pop-up window.

Method 2: Using Terminal (For More Thorough Removal)

For a more complete removal, use the Terminal application. While it may seem daunting, following these steps is straightforward:

Open Terminal: Access Terminal through Spotlight search ("Terminal") or by navigating to Applications > Utilities > Terminal.
List Partitions: Type diskutil list and press Enter. This displays your disk partitions. Carefully note the identifier (e.g., /dev/disk2s1) of the partition you wish to remove.
Erase the Partition: Execute the command diskutil eraseVolume jhfs drive /dev/[identifier] (replace [identifier] with the actual identifier from step 2).
Monitor Progress: Observe the progress bar. Once complete, a "Finished erase on…" message confirms successful removal.
Final Cleanup (Optional): For complete removal, repeat steps 3 and 4 from Method 1 in Disk Utility to remove any remaining partition entries.

Beyond Partition Removal:

After removing the partition, consider using a tool like MacKeeper's Smart Uninstaller to remove other redundant files and optimize your Mac's performance. This ensures a clean and efficient system.
