When it comes to rebuilding and recovering a hard drive that's not working right, Alsoft's DiskWarrior is peerless in the Mac realm. I don't know a single Mac IT professional worth their salt who doesn't swear by DiskWarrior, because it just works.
DiskWarrior excels at rebuilding the directory structure of your Mac's hard drive, and it does so by building a replacement directory instead of trying to patch the existing one. It's a data scavenger, and it's really excellent at its job. Sometimes I've even had success getting data off of physically failing hard drives using DiskWarrior.

Techtool Pro 7
Micromat's Techtool Pro 7 isn't just about recovering files off your hard drive, though it can do that. It can also do a thorough test on your Mac's memory modules to see if there are any RAM hardware failures (they do happen), along with things like Techtool Protection, which can more easily recover files that have been thrown in the trash, and eDrive, which lets you create an extra startup partition on your Mac's hard drive (handy for diagnostic maintenance work). Volume cloning, file and disk optimization (defragmenting), network monitoring and more.
It took until the 7.0.2 update before Techtool Pro 7 started support Macs with Fusion drives installed, but now that it does I feel a bit more comfortable about recommending it as a good option for Mac mavens looking for Mac diagnosis and drive repair software.

Data Rescue 3
Prosoft's Data Rescue 3 is another disk recovery tool. I've had good luck with it recovering deleted files from my Mac's internal hard drive and external volumes. It doesn't write to the hard drive; it requires an external drive to restore files to. The FileIQ feature is particularly handy if there's an obscure file type you want to recover. Provide Data Rescue 3 with an intact sample of the data you're looking to recover, and it'll sniff it out like a bloodhound.
I've had particular luck in the past with Data Rescue 3 getting back deleted or damaged files from camera cards, especially.

OnyX
Because OS X is a Unix-based operating system, you can do a lot more under the hood when you're accessing the operating system from a command line using the Terminal program. But unless you know what you're doing it's really easy to get frustrated. That's where Titanium Software's OnyX comes into play. This free utility gives you access to a huge variety of system maintenance, performance optimization and customization features by adding a graphical user interface to commands that you'd otherwise need to know Unix to be able to do anything with.
OnyX comes in handy when it comes to the deletion of Internet cache files that can screw things up, like DNS and browser caches, or individual system cache files, OnyX is a godsend. You can automate the rebuilding of your Mail mailboxes, Spotlight index and more. You have control over a wide variety of parameters for QuickTime, Safari, iTunes, your login window and more. Just be warned that with great power comes great responsibility: You can really screw things up if you don't know what you're doing. So be careful.

AppCleaner
This simple (and free) utility isn't exactly a repair utility but I'll include it anyway, because it comes in handy when it comes time to uninstall an application. Sure, the Mac makes it a lot easier to get rid of unwanted software than Windows, but don't be deceived — even if you've dragged a Mac application icon into the Trash, that doesn't delete the Mac app's entire footprint. Often times the app will leave behind configuration files, cache folders and other remnants that occupy disk space.
AppCleaner does a serviceable job of locating all the files associated with the app, and provides an index so you know just how much space they're taking up. Once you've got them all accounted for, click the Delete button and banish them forever. Sony arw software download for mac.

Disk Utility User Guide
Mac Os X Download
Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
Mac Os X Disk Repair software, free download
If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional checks, and then checks each volume. If you run First Aid on a volume, Disk Utility verifies all the contents of that volume only.
- In the Disk Utility app on your Mac, choose View > Show All Devices. Memu app download for mac.Note: If you’re checking your startup disk or startup volume, restart your computer in macOS Recovery, select Disk Utility in the macOS Utilities window, then click Continue. If you check your startup volume (Macintosh HD), make sure you also check your data volume (Macintosh HD - Data).
- In the sidebar, select a disk or volume, then click the First Aid button .If Disk Utility tells you the disk is about to fail, back up your data and replace the disk—you can’t repair it. Otherwise, continue to the next step.
- Click Run, then click Continue.If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. You can click Show Details to see more information about the repairs. Otherwise, you may need to do one of the following.
- If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.
- If you can replace a file or re-create it, delete it.
- If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.
- If Disk Utility can’t repair your disk, or you receive a report that the First Aid process failed, try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall macOS, then restore your backed-up data.
If your Mac has a Fusion Drive and you see a flashing question mark or alert, see the troubleshooting section of the Apple Support article About Fusion Drive, a storage option for some Mac computers.
