The end of the world must be near — Artie and I in almost. complete agreement. 😀. I haven't used — or needed — anything other than Disk Utility in years. Due to old habits I have kept TechTool Pro current but since the file and disk optimization routines don't make sense with SSD drives and can actually be hazardous to their longevity, I will think long an hard before upgrading it again, even though it has several unique hardware diagnostic tools.

If we knew what it was we were doing, it wouldn't be called research, would it?
