I'm a long-time TechTool user, but I'm running 10.12.6 Sierra with an SSD. Do I really need to upgrade from 9.5 to 9.6, especially since I have no intention of upgrading to High Sierra (10.13.x) until I'm extremely confident all the bugs and glitches have been worked out. Even then, something is gnawing at my gut about reformatting my SSDs to APFS since all my other externals are conventional HDs.
