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.

It also helps in performing basic troubleshooting tasks, even if you have no connection to the internet or access to the Mac App Store. El Capitan is no longer available in the App store for download; these instructions only apply if you've already downloaded it and associated it with your Apple ID. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.

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!

Drive Genius – Is this the Best Mac Repair App?!

Drive Genius is a disk utility application for Macs.

Its main features include:

defragmenting,
running benchtests,
directory repair,
integrity checks,
surface scans,
repartitioning,
cloning,
shredding data, and more.

With all these features, you can see why I ask is it the best Mac repair app overall!

This is actually the same program used to defrag Macs at the Genius Bar in Apple Stores.

Oh yes, Apple uses it.

Drive Genius also comes on a bootable DVD so you can run it even when a Mac will not boot.

Cost: $99.00

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!

You can also check out SuperDuper which has more features but costs $27.95.

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