TechTool Pro 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 Protection - Reengineered to better protect your Mac - TechTool Pro 9 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 TechTool Pro. All of that, wrapped in an entirely new interface.
• Check Computer - Now you're in control - Check Computer is a handy way to tell TechTool Pro 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 - TechTool Pro 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 usin 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 TechTool Pro 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. TechTool Pro 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 - TechTool Pro 7 took a revolutionary step in testing memory, making TechTool Pro's memory testing suite the most comprehensive test available for the Mac. In TechTool Pro 9, we've taken some of the additional advancements used by ATOMIC, our dedicated Memory Tester, and integrated them into TechTool 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.

What's New:

Тew In TechTool Pro 9.6
High Sierra and initial APFS compatibility
Apple is redefining how Macs use their disks. APFS, or Apple File System, is their new path forward. If you have upgraded, or plan to upgrade, to macOS High Sierra and have a solid state drive, your disk is going to get 'upgraded' to APFS. Be ready for APFS and macOS High Sierra with TechTool Pro 9.6 - it is the first third party Mac utility to offer APFS compatibility. And it has been fully tested to support High Sierra (macOS 10.13) as well. One extra upside to APFS drives: you don't need to start up from an eDrive to test them.

Trust us when we say that there is a lot going on with this new file system, so this is just *initial* support. Techtool Pro can now test and repair these disks, even eDrives on them, but we're still hard at work exploring the depths of this file system. Some more advanced features will be coming down the road.

NVMe Support
What's an NVMe, you ask? NVMe, like the SATA connection it replaces, is the phone line between your Mac and your disk. It's how your Mac can ask your drive if it thinks it's healthy. Micromat is the first company to translate this new connection, providing SMART health data from the drives in the latest Macs*. Not even Apple is providing this info yet.

*If your Mac is a MacBook from 2015 or later, a MacBook Pro from 2016 or later, or an iMac from 2016 or later and has a solid state drive, then it uses NVMe.

Internet Speed
While many Mac utility 'apps' only perform a small subset of tasks, TechTool Pro strives to be your full suite of tests and tools. To that end, you can now test your internet connection speed without opening a web browser. Simply choose the Internet Speed tool to see the speed and signal quality of your internet connection.
