Key Features

With hands on this secure and user-friendly software, you can fix a range of HFS disk errors and create a bootable USB to start-up inaccessible Mac. Let’s have a quick walkthrough of the salient features of this Mac Volume Repair Tool:

Repair Mac Disk Errors icon

Repair Mac Disk Errors

This Repair utility is capable enough to correct a range of Mac disk errors (such as 'Invalid index key', ‘Invalid key length',) that makes the opening, saving, or deleting files on macOS problematic. It even lets you repair minor disk errors without repairing the directory.

Repair Volume Directory icon

Repair Volume Directory

If your directory is not updated on a regular basis or is damaged, this software repairs the entire volume directory and replaces the damaged directory with the newly created one (repaired volume directory). You can seemingly mount a severely corrupt Mac volume and can make all your apparently lost data accessible.

Repair External Hard Drive Mac icon

Repair External Hard Drive Mac

This Mac disk repair software repairs corrupt directory structure of HFS formatted external hard drives. You just need to connect your external drive to Mac to start repairing cryptic disk errors such as Invalid B-tree node or Invalid Node Structure. You can also repair corrupt external solid-state drives using this utility.

Creates Bootable USB icon

Creates Bootable USB

This tool helps you repair corrupt start-up disk by allowing you to create a bootable USB. With the USB, you can boot your troubled Mac and further repair its startup disk. If the Mac is in the unbootable state, you can still use it. You just have to create a bootable USB on another Mac with similar configuration and then boot your Mac using this USB to repair the corrupt volume directory.

Repair Mac Disk Permissions icon

Repair Mac Disk Permissions

The software also includes Disk Permissions feature. Using it, you can Verify & Repair disk permissions on all bootable volumes in your system that includes any macOS. It allows you to quickly identify as well as address issues with both Apple-originated files and folders stored on your Mac’s boot volume.

Easy-to-Use and Interactive Interface icon

Directory corruption is typically manifested by various error messages. A few are given below:

Other signs include issues while opening, saving, or deleting file on the volume. In other cases, your Mac will refuse to boot up.

I am thankful to Stellar for this wonderful software, saves my very crucial files and folders from Hard Drive Volume loss.

The interface is really simple, fast & convenient. Never feel bored or too technical anytime while working with the software. Thumps up!



Almost saved a dying HD by repairing it to extent where I can access all my data and backup to another media. Simply Great.



Please keep-up the good work continue!

I am very happy after purchasing it. I was able to recover my file from volume that was crashed badly.

I had restored all my files using Stellar volume optimizer. $49 was my best investment i have ever spent on software.



Thank you, thank you!! I just to let you know that your software is superb! It fixed all my issues and was a big relief.



It got back an HFS partition back to life. I can't express my excitement seeing the drive up and running as usual. Thanks



My Mac had a troubled HDD. I tried my best:

*Repairing Mac in safe mode but didn’t make it.
*Booting into Recovery Mode but every time it restarts itself.

Went to a computer repair store and they said to replace the hard drive. I kept HD replacement as my last option. But before a replacement could happen I created bootable USB and repaired the startup disk drive with Volume Repair. The software took almost a day to scan, rebuild my corrupt disk but it successfully repaired the media. I have my Mac running again, and I feel the drive could live for some time. Happy I tried your application.



I gave up all my hope in repairing corrupt Solid State external hard drive 256 GB but Stellar Volume Optimizer brought it back 2 life. It literally saved me from losing files and the storage disk.



Bought an enclosure for my failed WD External 1 TB hard drive but still it failed to mount. Tried FSCK but didn't worked and almost all techniques failed until I ran Volume Repair. When are you adding macOS Sierra support?

I work with plenty of Mac OS Journaled hard drives. Though rarely but disk corruption occurs on my hard drives. I tried every single software that claims to repair Mac drive. Among all of them, I found Stellar Volume Repair the best for a couple of reasons (1) It covers up more than 30 cryptic disk errors (2) the software isn't overly priced, unlike other repair tools.

Stellar Volume Repair is an absolute answer to all those utilities that not just ask a high price for Mac hard disk repair but also don’t seem to perform as promised. I indeed recommend using this software as a perfect Disk Utility alternative. Moreover, you save around $50 with this application.



A great piece of application that worked on OS X Journaled hard drives. Another best part of this utility is its affordable price. Other software does the same task in almost double price tag. There is no point spending almost $100 in other product when Volume Optimizer can repair Mac in half the price

Stellar Volume Repair saved my Macintosh HD from going into a vegetative state. This software has an impressive built in technology that can repair the corruption on a Mac formatted disk. It saved my bacon on two occasions.



This product is a genius. It got rid of Invalid B tree node disk error on my Western Digital 1 TB hard drive. The UI is simple and documentation is appropriate. Since my drive was an external I didn’t require to create a bootable USB however I do keep a boot disk handy so that my startup disk is taken care of, when required.
