In addition to a backup, TechTool Pro includes TechTool Protection, which keeps an eye on your trash, allowing you to undelete that file you didn’t mean to delete. The best way to prevent data loss is to be prepared. Customize the size of your eDrive, up to 128 GB. You can even add other programs if you like. Instead of fumbling for your install DVD, or relying on the Recovery HD’s limited functionality, the eDrive gives you quick access to TechTool Pro along with several handy Apple utilities. The eDrive is what you’ll use to test, rebuild or defragment your main hard drive, but it is really helpful if your main startup disk goes missing. If your startup disk stops working, and you need another startup disk, TechTool Pro’s eDrive steps in to help. In addition to native Mac drive formats, Mac OS Extended and APFS, Techtool Pro supports testing and repair of MS-DOS (FAT32) and ExFAT formatted volumes. Most drive problems, however, result from data being in the wrong place, and can be repaired using TechTool Pro’s Volume Rebuild tool. Sadly, if something is physically wrong with the drive, it will need to be backed up and replaced, but the sooner this type of damage is detected, the fewer files - like cherished memories and important personal documents - will be lost. So, it's important to be able to test drives for problems and then repair them.
Because data changes so frequently, it can sometimes get scrambled. Your Mac's hard drive, even if it is a Solid State Drive, is more likely to experience problems than any other component on your Mac. 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. Techtool Pro will then send test results to any iOS device logged in to the same iCloud account. Simply download the new Techtool Remote iOS app (free on the App Store), and open it. Techtool Pro 12 is compatible with all current Macintosh models and system versions. With the release of version 12, it has become more proficient than ever. TechTool Pro has long been one of the foremost utilities for keeping your Mac running smoothly and efficiently.
