Improved Data Recovery

While regularly backing up your files is the best solution to safeguarding your data, sometimes things go wrong between backups. And when they do, it’s good to know you have additional options in getting your files back. Techtool Pro 9.5 has an entirely new data recovery system to help you do just that. And with the new Techtool Protection installed, your chances of recovering data are even better. Even if you unintentionally trashed files by mistake.



Cache Rebuild

Is your Mac taking longer to boot these days? Applications misbehaving? Difficulty connecting to websites and remote servers? Font menus not displaying properly? Techtool Pro 9.5 now includes a Cache Tool that can correct these problems and many more with a few clicks of your mouse.



System Maintenance

The OS that runs your Mac has many built-in system maintenance tools that run quietly under the hood. Now you can take control of these tools and utilize them whenever you see fit with our new System Maintenance tool. See when each utility was last run, or manually operate them if needed for troubleshooting and to help improve your Mac's performance.




General Improvements & Updated Compatibility

Making the world’s most complete Macintosh utility is not an easy task. Our engineers must continually update much of Techtool Pro’s code to keep up with new Macintosh models, updated operating systems, changes in the file system and new drives and hardware that are continually introduced. Having the latest version of the program assures that you can tackle almost any troubleshooting problem regardless of how new the hardware or software happens to be.

Mac Drive Testing and Repair

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. Because data changes so frequently, it can sometimes get scrambled. So, it's important to be able to test drives for problems and then repair them. 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. Most drive problems, however, result from data being in the wrong place, and can be repaired using TechTool Pro’s Volume Rebuild tool.

eDrive: Emergency Startup Disk

Emergency Startup Disk

If your startup disk stops working, and you need another startup disk, TechTool Pro’s eDrive steps in to help. 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. 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. You can even add other programs if you like.

Protect Important Data

The best way to prevent data loss is to be prepared. 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. You can also back up your directory structures, the ‘map’ of where your data lives, so that if you need to recover data from a corrupt drive, TechTool Pro’s Data Recovery tool will know exactly where to look. Better yet, use TechTool Pro’s Volume Cloning tool to create an additional backup.

Take It With You

The portability of TechTool Protogo is included with every copy of TechTool Pro. TechTool Protogo allows you to create a bootable diagnostic device that contains TechTool Pro and all of its most powerful tools as well as any of your own utilities you may wish to install. You can then use this device to boot, check, maintain, and repair Macintosh computers as needed. Simply launch Protogo, choose Protogo from the Mode menu, and use it to set up a diagnostic disk.


Complete Hardware Testing

TechTool Pro includes the most comprehensive hardware testing in the industry. On some machines there are more than 100 electrical and temperature sensors that TechTool Pro will check. If any of those sensors report values outside of their acceptable operating range, the new Sensors test will let you know. TechTool Pro also tests your Mac's cooling system, and can test laptop batteries as well, so you can catch small problems before they become big ones. In addition, test networking ports, WiFi and more using the Network and Bluetooth tests.


Advanced Memory Testing

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.








Diagnostics and Repair

Start with Check Computer to perform a complete diagnostic check of your Mac and hard drives. A single click of your mouse runs a SMART Check of your hard drive to detect impending drive failure, a RAM test, analysis of disk directories and more. If problems are found, advice is provided on how to proceed to repair the problem. Use Check Computer regularly as a part of your preventive maintenance program. Customize testing using built-in preferences.

Volume Rebuild

TechTool Pro will test, rebuild, and repair damaged directories on corrupted hard drives, and optimize the data directories when they are repaired. Volume Rebuild will display a comparison chart before directory data is replaced. Use Volume Rebuild to keep your drives operating at their peak performance.

SMART check

Smarter SMART Check

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.

Partition Map

TechTool Pro will test and repair hard drive partition maps. The Partition Map test will verify the health of the partition map and the Partition Repair tool will repair any errors found in the partition map.

Memory Test

RAM problems are quite prevalent and can cause a variety of crashes, program errors and even data loss. We've seen many cases where a user will be chasing down a disk or extension problem when their issue was simply a faulty and inexpensively replaced memory module. As part of the RAM test, we've also added an SPD report that shows you an enormous amount of technical and other interesting information about your computer's memory.

Using TechTool Pro, you can easily create an eDrive, an extra startup partition based on the active system volume, which can be used as an emergency startup partition or to perform regular maintenance on your Mac. The eDrive is based on your specific Macs system and includes TechTool Pro's tools for Mac repair. Using the eDrive, there's no need to reformat or to boot from a DVD or secondary hard drive.

Volume Cloning

Volume Cloning creates exact duplicates of your volumes for trouble-free archiving to backup your data and applications. Cloning volumes can also be helpful if you are upgrading from a smaller size hard drive to a larger drive. You have the options of creating a duplicate of an entire disk, file syncing by adding only the changed files to a clone, or cloning to numerous disc image formats. If you have an available drive, you can even use the tool to optimize disks that are especially fragmented.

Volume and File Optimization

TechTool Pro performs both file and volume optimization. File optimization defragments individual files on the hard drive. Volume optimization consolidates the free space on a hard drive. For full optimization, perform Volume Optimization after File Optimization. The resulting optimization simplifies the file storage layout and may enhance the overall performance of your drive.

Network Monitoring and Connectivity

TechTool Pro will monitor the configuration of your local area network (LAN) by revealing the active services and ports on each selected machine or Bonjour supported device on your LAN. This information is important for strengthening security on a specific machine, Bonjour supported device or your overall LAN, and is also helpful in tracking what devices have been in use in the past that are no longer available since the last time monitoring was performed.
