"TechTool used to be fine 10y ago"
Cannot see any advantage over DiskUtility & functioning Backup (Time Machine).
- does not solve problems.
- does not work with Apple RAID card
- flashy but user-unfriendly interface
- poor explanations of problems found and measures taken
Overall, TechTool Pro is a program with colorful illustrations and symbols. It is however completely unclear what it does to keep your mac moving. I am waiting for someone to provide evidence (images before and after of analysis) that it does something useful.
