Security Status

TechTool Pro for Mac has long been one of the foremost utilities for keeping your Mac running smoothly and efficiently. With the release of version 9, it has become more proficient than ever. Techtool Pro provides tools for maintaining and troubleshooting your Mac, including drive repair, RAM testing, and data protection.

Features and Highlights

TechTool Protection - Reengineered to better protect your Mac
TechTool Pro for macOS includes the option of installing a system preference pane to keep watch over your Mac. New features include check for I/O errors, Power On Self-Test errors, Mac notebook internal battery condition, and RAID status (if applicable). It also includes the same improvements to the SMART check in the app. All of that, wrapped in an entirely new interface.

Check Computer - Now you're in control
Check Computer is a handy way to tell the tool to run the entire suite of tests to give you the best possible snapshot of your Mac's health. Sometimes, though, it's nice to be able to leave tests out, or to skip certain drives. Using the new configuration panel, you have total control of the Check Computer suite. Power to the people.

Partition Map - new drive test
The app has long been known for testing your Mac's file system. It is important also to test the data structures that contain the Mac's file system: the Partition Map. The new Partition Map test checks the partition map of a given drive for errors. Partition map errors can cause entire volumes to go missing, or prevent a Mac from booting. If errors are found, they can be repaired using the Partition Repair tool.

Partition Repair - new drive repair tool
Along with Volume Rebuild, which repairs Mac file systems, the Partition Repair tool repairs the remaining portions of the drive which keeps track of the volumes on your hard drive. This includes hidden partitions which keep track of your Mac's startup process. The Partition Repair tool does just what it says, repairing the partition maps or drives where needed.

SMART Check - Now even smarter
Hard drives include a technology called SMART (Self Monitoring, Analysis and Reporting Technology) which can inform a computer about the health of its hard drives. In most utilities, just the overall results - passed or failed - are reported to the user. In the failed state, often there is little or no time to back up data before the drive fails entirely. Previous versions of the app reported the overall status of each attribute, but some attributes don't contribute to the failure of a drive. Now, the SMART Check has gotten smarter. The app now knows which attributes contribute to drive failure, and will report a failing result before the drive fails completely. Giving you time to rescue your data.

Memory Test - Now better than ever before
The program took a revolutionary step in testing memory, making the app's memory testing suite the most comprehensive test available for the Mac. "In TechTool Pro , we've taken some of the additional advancements used by ATOMIC, our dedicated Memory Tester, and integrated them into Tech Tool Pro." Now, memory is 'cleaned' before testing, reclaimed from macOS, maximizing the amount of RAM that can be tested.

Processor Benchmark
Get an objective measurement of your Mac's processor performance. The Processor Benchmark too uses industry-standard measurement algorithms to test processor performance. Using this tool, you can get metrics that can be used to compare processor speeds apples-to-apples. Avoids the confusion of comparison using Megahertz.

Bluetooth - New test
"Most Macs depend on Bluetooth to connect to the tools we use to interact with our computers: the keyboard and mouse. Bluetooth problems can result in dropped connections with those devices, which can be very frustrating. Verify the proper operation of your Mac's Bluetooth hardware. Make sure that not only your input devices, but also your audio and fitness devices can connect to your Mac by checking the Bluetooth hardware on your Mac."

Network Interfaces - New test
Most Macs spend the majority of their lives connected to the internet. If the ethernet or wifi adapters in your Mac aren't working, the valuable connection to the internet can fail. The new Network Interfaces test can test any connected network interface for errors. It not only tests ethernet and wifi, but also any other supported internet connection, ethernet over USB, VPN connections, even a FireWire network conneciton. Ensure the reilability of your internet and intranet connections by testing your Mac's network interfaces.

Note: Requires 64-bit processor.

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.

Test your iPhone or iPad battery:
- Recent reports have shown that battery condition can affect the performance of your iPhone and iPad. If your iOS device is connected to your Mac, Techtool Pro can now test your device's battery, and give you a host of other important battery data as well. Find out if your iPhone or iPad is running at its full potential.

More control at your fingertips:
- eDrive and Surface Scan now give you more flexibility. Need your eDrive to be a big larger for additional applications or files? The eDrive tool now gives you the option of selecting a larger size partition. Want to scan a particular portion of your drive for bad blocks? Surface Scan can now start at any location on your disk.
