TechTool Pro has long been one of the foremost utilities for keeping your Mac running smoothly and efficiently. With the release of version 10, it has become more proficient than ever. Techtool Pro 10 is compatible with all current Macintosh models and system versions. 

TechTool Pro 10 Features: 

Better disk repair 
We'll bet that many of you have flash drives, memory cards, even hard disks that aren't formatted for Mac. Techtool Pro 10 now supports testing and repair of MS-DOS (FAT32) and ExFAT formatted volumes. This means that you can now test and repair those memory cards from your camera, or that thumb drive your friend gave you with all those important files. Avoid losing your precious pictures - find out if those cards and drives have problems before you run into data loss. On top of that, testing the start up volume is now available for both Mac OS Extended and APFS without starting up from the eDrive. 

Results on the go 
Techtool Pro now supports iCloud Drive. Simply download the new Techtool Remote iOS app (free on the App Store), and open it. Techtool Pro will then send test results to any iOS device logged in to the same iCloud account. So if you have a long test (or tests) running that you want to know the results of, but you need to hit the road, you can now get notified of your results anywhere you have an internet connection.
