After years of being a loyal customer, I have decided to stop purchasing TechTool Pro due to aggressive pricing. Even with a discount coupon, TTP is not value for money anymore. I used to pay around $25.00 for an upgrade using a discount coupon. If I want to purchase it now, I have to pay twice as much. I used to run TechTool Pro Volume Rebuild tool to make the disk directory more efficient and sometimes repair a corrupted volume. However, it has been four years that I haven’t needed to use the Volume Rebuild Tool; the reason for this is that Apple has improved its macOS to the point where you hardly need to use a repair tool. Last year, I only launched TechTool Pro three or four times to check the health of my Mac, and it didn’t report any problems even after getting a couple of freezes and crashes. Thanks to Apple for continually bringing improvements to its macOS.
