I have put together a list of what are, in my opinion, the ten best Mac disk repair software and other excellent Mac tools for troubleshooting, diagnosing, and repairing a Mac. Many of them are free or offer a free trial. As Macs continue to gain market share, there is an increased likelihood that you will have to support them if you are a tech. And even if you aren’t a tech, it’s good to know which tools are the best to use when it comes time to repair your own.

• Remo HD Video Repair Utility is a great way to repair corrupt or damaged MOV files. Using a read mechanism, the software extracts contents of the file, fixes issues and creates a new healthy MOV file. So, the original file is not harmed during the repair process. Now let’s look at some of the interesting features of the software.
• Run the video repair tool by double-clicking the application ‘gs.app’ (Mac) or ‘gs.exe’ (PC). Click on ‘Choose movie’ and choose a non-broken sample (playable) movie of your camera. Using a non-broken sample movie you can verify if the program fully supports your type of camera.

Introduction to our Top 10 Mac Repair Software

Did you know there are several Mac disk repair options that each function differently and one may suit your needs better than another? I detail several for you below so you can decide.

More than just a list of disk repair software, I provide many Mac software solutions for you and your clients! Even better, some are free!

Want to clone a Mac drive? Want to monitor a Mac’s hardware sensors? Want heroic system recovery for mere mortals?! Oh, there are some great software here! Read on.

TechTool Protogo

TechTool Protogo is a Mac repair program suite which contains three of Micromat’s best Mac repair tools; TechTool Pro 8, TechTool Pro Classic, and DiskStudio.

Protogo creates a bootable Mac repair toolbox with these tools as well as any of your own tools on a portable hard drive or flash drive.

You can then boot from this drive, bypassing the OS, and run diagnostics on a computer to determine problems.

Protogo also allows you to repair and recover data from problematic hard drives as well as defragment, optimize, and securely delete data.

Cost: $129.99

Memtest OS X

Memtest OS X is a memory testing program for Mac OS X. It is a command line utility so it can be ran in OS X or in Single-User Mode if your Mac will not boot.

It is great for testing intermittent system problems when you are having trouble determining if it is a memory problem.

If you prefer memtest with a GUI front-end, then be sure to check out Rember.

Rember will run in OS X but will not work in Single-User Mode so Memtest OS X is the better option.

Cost: $1.39

Mac Disk Repair – DiskWarrior 5

Disk Repair for Macs – DiskWarrior utilizes a unique disk repair method for Macs

DiskWarrior is arguably one of the best hard drive repair programs for the Mac.

It works differently than other data repair programs.

Instead of trying to rebuild the damaged data itself, DiskWarrior builds replacement data based off of the original data.

It then verifies the new data structure based on the original to make sure it is error free.

You can also use DiskWarrior as a preventative maintenance utility for hard disks.

When run, it rebuilds your directory eliminating any damage that you may not be aware of. It also optimizes the directory for better performance.

Cost: $99.95 but look for a trial.

If it is more serious and your Mac’s hard drive has crashed, I have provided an extensive data recovery guide with a list of Hard Drive Recovery Tools in my article How to Recover Data from a Crashed Hard Drive.

First Free Disk Repair-Mac – OnyX

Onyx is a maintenance, optimization, and personalization utility for Mac OS X.

It allows you to run hard drive diagnostics, run system maintenance tasks, delete caches, and configure tons of OS X hidden features.

Even if you aren’t using it as a repair utility, it is a great application to help keep your Mac running in top shape.

Cost: Free!

Mac Data Rescue

Data Rescue is a data recovery program that focuses purely on recovering data from corrupt drives instead of hard drive repair.

It scans the corrupt drive analyzing all of its contents and allows you to choose which data you would like to recover.

It even scans for deleted files. Data Rescue II restores the data to a separate drive leaving the original data intact.

It comes with an emergency boot CD that you can use to recover data when the computer will not boot and it also works on drives that won’t mount.

Cost: $99.00

AppCleaner

AppCleaner may not be classified as a repair tool but it can be used as one.

When you are having trouble with an application in OS X, you can simply remove it by dragging it to the Trash.

However, this still leaves behind the applications preferences, caches, and other files that could still cause the same problem after you reinstall it.

AppCleaner will remove all of these files making sure that the app is completely gone before you attempt a reinstall.

Interesting interface!

Cost: Free!

Mac Backup – Carbon Copy Cloner

Carbon Copy Cloner is a simple yet very effective backup utility for the Mac. Like most other backup utilities, it can be scheduled to backup your Mac on a regular basis.

The best part, however, is its ability to completely clone a hard drive with it still being bootable.

This tool comes in very handy when you are replacing hard drives, setting up multiple Macs, or recovering from a system crash.

Carbon Copy Cloner is donation-ware so you can download it for free without any restrictions.

Maybe you will be so pleased you will buy them a coffee anyway!

However, if you just need a simple backup and cloning utility, Carbon Copy Cloner does a great job.

Apple Mac Disk Repair – AppleJack

AppleJack is a troubleshooting utility for Mac OS X. It runs under Single-User Mode so it can be used even when OS X will not boot.

AppleJack will repair disks, repair permissions, cleanup cache files, validate preference files, and remove swap files.

You can select these tasks individually or have AppleJack run all of them and even reboot when finished.

Unfortunately, at the time of writing this article, AppleJack is not yet compatible with Leopard but a new version is in the works. Be sure to check their page frequently for an update because this is an invaluable tool.

When I updated this article for 2020, I checked on SourceForge and there were over 600 downloads last week!

Digital file corruption on Mac signifies unintended changes of bits (0s & 1s) that a file is composed of thereby damaging its integrity. The alteration of bits can occur in the header or the main content of a video or picture file. In case one or more bits changes in the header data, the file may not open or throw an error message. If some bits modify in the main content, the file may have imperfection after opening or may even turn garbled.

The below infographic summaries the common reasons for a file corruption on macOS.

5 Reasons for Digital File Corruption

1. Power failure during the data writing/transferring process

Fix: Plug the power cable to your MacBook when its battery level is low. While transferring data, always copy the file from the source and paste it to the destination to prevent file corruption.

2. Defect or bug in the application that opens the file

Fix: Keep you macOS Mojave up to date. Update all the native and 3^rd party applications that are installed on your macOS. Updates fix the bug or defect present in any apps that can corrupt your audio, video or photos.

3. A malware infection can corrupt digital files

Fix: Scan your Mac by using anti-malware software. Scanning will help you determine potential threats and remove a malware that your storage drive may be infected with.

4. Bad sectors on the storage drive

Fix: Run Disk Utility’s First Aid to fix minor logical issues with the storage drive.

5. Corruption during file conversion/processing

Fix: Create a redundant copy of the file and use the duplicate file while converting from one form to another or processing it. Working with the duplicate saves the original file from corruption.

How to Repair Corrupt Digital Files on Mac?

Method 1: Use a Mac Hex Editor

Open a copy of the corrupt file and a perfect file of the same kind in a Mac Hex Editor, such as iHex or Hex Fiend. Compare the header data of both the files. In case, you could detect the hex character changes in the corrupt file, edit the hex data and save it. The rectified file may normally open if the corruption is minor and detectable. The process needs to be repeated for all the corrupt files, which is tedious.

Method 2: Use a Premium Repair Software for Mac

Repair your corrupt digital data such as photos or videos by using a premium repair tool. Instead of employing different software, use the versatile D-I-Y tool Stellar Data Recovery Premium for Mac that offers two repair functionality—Repair Photo and Repair Video.
