12.0.2
04 March 2020

Hard drive and system repair-and-maintenance tool.

Overview

TechTool Pro has long been one of the foremost utilities for keeping your Mac running smoothly and efficiently. With the release of version 12, it has become more proficient than ever.

Main features:
  • TechTool Protection - TechTool Pro 12 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 - 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 - 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 - 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 - 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 - 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 10, 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 - 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 - 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.

An A1 app as far as functionality, always has been. I've been trusting and using it for years. If you're happy to pay for it then I for one would recommend it. *However* I'm giving it just 3 stars because the of the upgrade pricing policy. It's always bugged me, but I've lived with it because it's so good, and I'm so invested in it. But the last few full version upgrades have come out like diarrhoea at $A50 each time. I'm blowed if I'm going to keep that up. So I won't be upgrading to v12 impressive though it sounds. And I'll be thinking very hard about switching. So off to do the research.

Has everything I could ask for. Total System and disk care. The upgrade price is not cheap...then again it is not a subscription and software development in the age of SSDs and Catalina is not easy.

Where the hell is uprade for DiskWarrior, by far the best drive maintenance and repair too, which leaves al the others in the dust? Seems the next MaOS will be released before the lazy ass developer gets around to finally releasing a Catalina-compatible version of this great utility..assuming they ever will.

My understanding is that Alsoft don't see any point in pushing out a new version until Apple bother to finish publishing documentation about APFS. Without it, Alsoft can only support repair of HFS+ volumes. IOW: PESTER APPLE! It's their fault. (I personally am sick of Apple's profound BS of recent years). - - Meanwhile, only Micromat has dared to support APFS volume repair, and that took awhile due to the same Apple imposed limitations. - - One happy thought I can pass along is that after having been using APFS for the past full year, I have never found it needed repair. That's from using both Disk Utility via the repair volume AND TechTool Pro 11. APFS is significantly more bulletproof than HFS+, seeing as it is essentially ZFS.

My experience is different. I have had no end of problems with APFS, quite likely due to Snapshot handling.

Derekcurrie, when you say that only Micromat dares to support APFS volume repair, does that mean TechTool Pro’s Volume Rebuild works on Catalina? I too miss DiskWarrior’s volume rebuild, but I also own TTP but haven’t upgraded because I was waiting for their APFS support. Is it finally a fully functioning utility again?

I bought an upgrade to TTP 12 today. Once bought, it showed me a dialogue box from which I downloaded the full version. If you have an account on their site then you can also download it by logging in to your account. However, giving it one star just because you couldn't download it is not fair! Hope this helps.

This app rocks! I use an SSD and Catalina, though they say the current edition does not "Totally support Catalina" I use it constantly and it is my #1 standby Drive utility. Vastly better than DriveGenius 5 or the new 6. In Mohave 5 and 6 will report falsely of disk damage and neither of those support Catalina and seem to have no immediate plans to do so. TechTool support treats you like a human and never makes you feel like an idiot or that you are bothering them. Yes file optimization works...you simply have to create am bootable partition use it and TechTool is fully operational. The app even tells you so if you try to do anything with the Startup drive. The Bootable portion is created quickly with no effort on your part. You simply designate where you want the Bootable partition created and the rest is automatic.

Some comments: -- (1) If you're using APFS volumes, they don't officially support file or volume optimization. On SSD drives, optimization is pointless anyway. (2) It's great to hear TechTool Pro 12 has no problems making Drive startup drives. They were a chronic problem in v11. (3) I hope the false 'partition damaged' warnings are gone in v12. I got sick of them in v11. (4) DriveGenius 6 does not exist in public. DriveGenius 5 does not support APFS or macOS 10.15.

Unless they have changed their upgrade policy, this makes no sense to purchase now as there will be an upgrade next month to take advantage of MacOS Catalina and it will have a charge for it.

Just a word of caution for potential new purchasers of TechTool Pro. While TechTool Pro can do volume rebuilds on APFS formatted volumes and disks, as of version 11.0.4, both File Optimization and Volume Optimization still do NOT work on APFS volumes and disks. While Apple has long claimed that file optimization has become meaningless in light of modern huge hard drives and fast machines, some Mac users still like to optimize anyway. If you are one of such people, and if you do use APFS, then please be aware of this point before making a purchase.

It turns out there is major flaw in APFS. When used on spinning hard drives, it causes huge fragmentation EVERY TIME IT WRITES to the drive. So deframentation/optimization is most needed.

Partial Review:

v11.0.3 still has some minor bugs. The most annoying is when your Preferences chosen are RESET to the DEFAULT without your permission.

In my case, I do NOT want Directory Backup OR Volume Usage OR Trash History left on. Upon Restart it is common for all three of these settings to be checked ON again. I’ll have to dig further to understand why this happens. But my best guess is that these settings are (wrongly) stored in User Cache rather than in a PLIST permissions file. If/when I dump my User Cache appears to be when this bug enacts itself.

Also, there have been reports of problems creating eDrives (a temporary bootable partition for repairing native Mac boot partitions). I still have to check if the bugs have been removed in 11.0.3.

Overall, despite the minor bugs, TTP 11 is impressive. It remains (sadly) the ONLY disk repair utility that can (mostly) repair APFS volumes.
• DiskWarrrior still cannot, with no sign of progress.
• Drive Genius still cannot, with no sign of progress.

WHY the interminable lack of full support for APFS in any Mac utility??? The blame goes to Apple. Inexplicably, Apple is being lazy, not finished APFS documentation to developers. This annoyingly fits with Apple's recent Mac malaise, now extending to over three years since APFS was announced and its first beta provided. Developers are uniformly fed up with this specific lack of support from Apple.

IOW: Don't blame Micromat or the other repair utility providers. Thank Micromat for striving forward with actual APFS repair support, despite Apple.
