Using the new Check Computer Suites, you can set up a variety of test suites for your needs. Use the built-in Full, Intermediate or Quick suites or make your own suite of tests to perfectly suit your needs. The Full Suite does what it sounds like, running every test and checking every drive. The Intermediate Suite leaves out the Surface Scan test to help save time, while the Quick Suite tests your Mac excluding your disks, for a quick look at the health of your Mac's hardware. Customize any of these or create your own suite from scratch to test your Mac exactly as you would like.

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. 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.

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. Customize the size of your eDrive, up to 128 GB.

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.

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. Here are a list of recommended drives that work well as Protogo devices.

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.

Techtool Pro's memory testing suite is the most comprehensive among general hardware utilities. Techtool Pro, takes advantage advancements used by ATOMIC, our dedicated Memory Tester, and integrates them into testing your memory. Now, memory is 'cleaned' before testing, reclaimed from macOS, maximizing the amount of RAM that can be tested.

Techtool Pro has been able to test your Mac's battery for quite a while. But, 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.

Techtool Pro 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.

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.

Drive Testing and Repair

Techtool Pro will test, rebuild, and repair damaged directories on corrupted Mac OS Extended hard drives, and optimize the data directories when they are repaired. Techtool Pro can also repair Apple's new APFS file system, standard Mac OS Extended volumes, as well as MS-DOS (FAT32) and ExFAT formatted volumes.

When rebuilding Mac OS Extended volumes, Volume Rebuild will display a comparison chart before directory data is replaced. Use Volume Rebuild to keep your drives operating at their peak performance.

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.

eDrive

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.

If needed, the eDrive's size can be expanded to fit your needs.

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.**

Data Recovery

Techtool Pro helps you recover your data from corrupted drives or volumes that don't mount on the desktop to save the data to another location.† Use the Trash History feature to track the location of deleted files and increase the chance of their recovery in the case of an accidental deletion.

Processor Benchmarking

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.

Network and Connectivity Testing

Techtool can test your Bluetooth, Wifi, Ethernet and any other network network interface. Troubleshoot problems staying connected to wifi, or problems connecting to Bluetooth peripherals such as speakers, keyboards, and more.

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.

Protection Preferences

Techtool Pro includes the option to install the Techtool Protection system preference, where you configure automatic functions that operate in the background. In particular, you can configure Protection to track deleted files, monitor the free space on your hard drives, save backups of critical directory data to help with recovery in the event of drive corruption, and to monitor the SMART routines of your hard drives. Checks include scanning for i/o errors, power on self-test alerts, battery problems and RAID errors. If problems are found, Protection delivers onscreen and email alerts.

Techtool Pro is feature-packed with benefits that all Mac users need for comprehensive diagnostics, repair, and maintenance. To ensure your Mac stays optimized and trouble-free, make sure you use Techtool Pro regularly and keep your Mac running at peak performance.
