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:
Diagnostic Tools For Mac Computer
- defragmenting,
- running benchtests,
- directory repair,
- integrity checks,
- surface scans,
- repartitioning,

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.
Cost: Free! (donation-ware)
Apple Mac Disk Repair – AppleJack
Best Mac Diagnostic Software
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!
Cost: Free! (open-source)
Hardware Monitor
Hardware Monitor is a utility that allows you to view data from the hardware sensors in a Mac.
It currently has support for temperature readings, battery data, voltage, current, fan speed, power and load, ambient light, as well as user-defined artificial sensors.
It’s a great utility to use when simply trying to find out if your hardware is malfunctioning.
Cost: € 7.00 (can also be purchased with U.S. Dollars)

System cleanup in one click
Make your Mac fast and secure with CleanMyMac X.
We associate a Mac with quality, capacity, speed, and reliability. But it might happen so that your Mac underperforms and unpredictable issues occur. Before taking it to the nearest Apple service, you can try to identify the problem by yourself. That will save your time and money, and prevent serious system crashes. Identifying whether the issue is a hardware or software one will determine the possible actions and next steps.
When we deal with the hardware problem, the first thing to try is to perform Apple Diagnostics (or Apple Hardware Test). It will help you reveal the process that causes the problem and lowers Mac productivity.
Apple Diagnostics is an easy-to-understand tool that provides detailed results and suggestions with the next steps. Whether you are a techie or not, you'll get everything easily.
What is Apple Diagnostics?
Apple Diagnostics is a built-in test that helps detect what hardware components are causing the problem, and find system failures. The test checks RAM, power controller, logic board, battery, and other wireless modules.
That was the hard part. And the easy part is that you can run Apple Diagnostics in just a few steps. The whole process will take about 2-5 minutes — but ultimately saves hours of your time.
A great feature of Apple test is that after hardware checking, it displays an error code, offers you clear solutions, and the assistance of Apple Support. You can write out the error codes (known as reference codes), and either do the research on/ your own or contact Apple.
When referring to Mac hardware test, you might also hear about Apple Hardware Test (AHT). This is an older brother of Apple Diagnostics (AD), and they have some minor differences. Mainly, the results of AHT aren't conclusive and descriptive. AHT is used in Macs released in 2012 or earlier, while AD is a more advanced analog that works with newer Macs.
Essentially, a Mac hardware test is the great tool to help you understand the problem. And if it doesn't have a fix for it — there are more advanced tools that you can use to troubleshoot Mac issues. More about that in a moment.
How to run Mac diagnostics
Running a hardware test on Mac may seem like a complicated process, but believe us — that's not:
- Disconnect all the peripheral devices (printer, cables, external DVD drive) except the keyboard, mouse, display, and speakers. Make sure your Mac is connected to mains power and the internet.
- Select Apple Menu > Restart
- Press and hold the D key until you see a list of different languages on the screen
- Select a language. Apple Diagnostics starts automatically.
- Wait for about 2-5 minutes until the checking is completed. If any problems are found, you'll see the options of solutions and an error code.
After that, you can either repeat the test, get more information, restart or shut down the Mac. That's it - an easy 5-step process, as promised.
Apple recommends to print out the instructions to keep them close at hand and make sure you don't miss any step. Or, you can take a photo. Right, that's what people do in 2020.
What are the common Apple Diagnostics results
After performing a Mac hardware test, you'll get the list of found issues with detailed descriptions and related reference codes. Each code stands for a particular error and helps you quickly figure out the next steps. Usually, an error description will suggest possible solutions. However, to fix a specific problem, Apple Diagnostics might recommend you to contact Apple or take your Mac to an Apple Authorised Service Provider or AppleRetailStore.
There could be the case the system testing doesn't find any issues.
In this case, you have a few options. Please note that they are mutually exclusive, which means you should choose the best option for you:
- Repeat the process by hitting Run the test again
- To get more information on support and service options, click on Get started:
- The macOS X recovery will start
- Send your serial number and reference codes to Apple by clicking Agree to send
- Follow the on-screen instructions.
- Restart your Mac
- Hit the Shut Down button.
Because well, sometimes a small mistake might hamper it all. Maybe the first time you tried to run Apple Diagnostics, your power adapter wasn't plugged in. Connect it and try again — this will help fix the problem.
What if you can't run diagnostics
You can face the problem when Apple Diagnostics simply doesn't work. Don't worry, it's solvable. There might be a couple of reasons why this happens:
- Some external devices are plugged in. Double-check you've disconnected everything except the keyboard, mouse, display, and speakers.
- A part of the diagnostics system can be damaged. You can solve the problem by restarting the Mac while holding down Option+D. This will start an internet-based hardware test.
- Firmware password might be the problem. Make sure you turn it off while performing hardware testing.
What if diagnostics found no issues
In case Apple Diagnostics identifies no hardware issues — but your Mac is still misbehaving — maybe, software is the problem.
Often, Macs are slowing down, freezing, or behaving strangely due to full storage, malware, leftovers from uninstalled apps, large and old files. The good news is you don't have to guess, or install many applications to fix each problem separately. An all-in-one tool called CleanMyMac X has all the required functions to test your Mac from a to z. It cleans up, protects, and speeds up your Mac.
Just one click to optimize your Mac — CleanMyMac X makes it fly like a rocket.
Here's how CleanMyMac X optimization works:
- Go to the Maintenance tab
- Specify what should be done. For example, if you want to speed up your Mac by freeing up some space, check the box next to Free Up Ram”. You can select all the tasks at a time, or choose the particular ones.
- Press Run.
Yay, you launched a rocket!
The most common problem that impairs system performance is the junk files that clutter your Mac. You might not even know about them. Luckily, CleanMyMac X has a solution for this, too. Resolve various errors with a great feature called System Junk:
Diagnostic Tool For Macbook Pro
- Hit Scan
- Once you see the results, press Review Details
You'll see the list of all items that should be cleaned or fixed. You can review the results and deselect those items you're not ready to let go. CleanMyMac X will omit them while cleaning up your Mac. Once you're ready, hit Clean.
Wow, your Mac feels much better now.

Conduct an advanced system testing and optimization that will secure and speed up your Mac with an app like MacPilot.This powerful utility unlocks over 1200 hidden features that go beyond standard Mac settings.

Conclusion
