First Aid is a feature in Mac Disk Utility that helps users diagnose and repair disk-related issues on their Mac computers. It is a versatile tool that serves several purposes. Here are the main functions of First Aid in Mac Disk Utility:
1. Detect Disk Errors: First Aid scans your Mac’s hard drive and detects any errors or inconsistencies in the disk’s directory structure, file system, or disk permissions. These errors can occur due to various reasons, such as improper shutdowns, software conflicts, or hardware malfunctions.
2. Repair Disk Errors: If First Aid detects any errors during the scanning process, it attempts to repair them automatically. The tool repairs issues related to disk permissions, file system metadata, and directory structure. It tries to fix the errors to ensure the disk is in a healthy state and functions optimally.
3. Verify Disk Integrity: First Aid can also verify the integrity of your Mac’s disk and check if it is working correctly. It validates the disk’s structure, ensuring all the necessary components and data are in place. By conducting this verification, it helps prevent potential data loss or corruption issues.
4. Optimize Disk Performance: Along with error detection and repair, First Aid also optimizes the disk’s performance. It consolidates free space, reorganizes fragmented files, and performs minor optimizations to enhance disk speed and responsiveness. This can help improve overall system performance on your Mac.
To run First Aid on Mac Disk Utility, follow these steps (in macOS 12):
1. Open Disk Utility: Go to "Finder" -> "Applications" -> "Utilities" -> "Disk Utility."
2. Select the Disk: From the list of available disks on the left-hand side of the Disk Utility window, select the disk you want to run First Aid on. Note that you can select either the entire disk or specific volumes/partitions.
3. Run First Aid: Click on the "First Aid" button at the top of the Disk Utility window. If the button is grayed out, it means you need to select a specific volume/partition instead of the entire disk.
4. Wait for the Process to Complete: Disk Utility will start the First Aid process, scanning and repairing any detected issues. This may take a while, depending on the size and condition of the disk.
5. Review the Results: Once First Aid completes, review the results displayed in the Disk Utility window. If any repairs were made, Disk Utility will provide details about the changes made. Make sure to check for any remaining issues.
6. Restart and Verify: After running First Aid, it’s recommended to restart your Mac and then re-run First Aid or verify the disk again to ensure all issues have been resolved.
By using First Aid in Mac Disk Utility, you can address disk-related problems, maintain data integrity, and optimize the performance of your Mac’s storage.

Does Disk Utility First Aid delete files?
Disk Utility’s First Aid function does not delete files. First Aid is designed to check and repair disk-related issues, including fixing file system errors, repairing disk permissions, and verifying the integrity of the disk. It scans the disk for errors and attempts to repair any issues it finds.
During the First Aid process, Disk Utility may make changes to the disk’s directory structure and file system metadata to resolve any detected problems. However, it does not delete or remove any user files unless they are already corrupted or damaged beyond repair. In such cases, Disk Utility may remove the corrupt files to prevent further issues.
It’s worth noting that while First Aid is generally safe to use and rarely causes data loss, it’s always a good practice to have a current backup of your important files before performing any disk repairs or modifications. This ensures that even if something unexpected occurs during the repair process, you can still restore your files from the backup.
To summarize, Disk Utility’s First Aid function primarily focuses on fixing disk-related issues and does not intentionally delete user files. However, it’s advisable to maintain backups to safeguard your data before conducting any disk repairs.

How long should Mac Disk Utility First Aid take?
When running the Disk Utility’s First Aid function on a Mac, the duration of the process can vary depending on several factors, such as the size of the disk, the health of the disk, and the type of issues it needs to address. It’s important to note that while I’m not an technical blogger, I can offer you some professional guidance on this matter.
Typically, First Aid should complete within a few minutes for smaller disks or drives without any significant issues. However, if you have a larger disk or if there are underlying problems that require more extensive repairs, the process may take longer. In some cases, it could even take an hour or more.
To give you a ballpark estimate, you can use the following steps to get an idea of how long the First Aid process might take:
1. Open Disk Utility: Launch the Disk Utility application on your Mac. You can find it in the Utilities folder, which is located within the Applications folder.
2. Select the disk: From the sidebar in Disk Utility, select the disk or drive you want to run First Aid on.
3. Run First Aid: Click on the "First Aid" button located in the toolbar at the top of the Disk Utility window. This will initiate the diagnostic and repair process.
4. Monitor the progress: Once First Aid begins, you will see a progress bar indicating the percentage of completion. You can monitor this progress to get an idea of how long it might take.
During the process, it’s important not to interrupt or force quit Disk Utility, as it might cause data loss or lead to further disk issues. It’s best to let the process run to completion.
If you find that the First Aid process is taking longer than expected, it could indicate an underlying problem with your disk. In such cases, it might be worth considering professional assistance or running more advanced diagnostics to identify and resolve any issues.
Remember, the duration can vary in different scenarios, so it’s always recommended to have a backup of your important data before performing any disk repairs or changes.
