I just d/l'ed OnyX 3.6.8 directly from this page at Titanium Software, its developer, and the .dmg opened instantly, with no installer involved...merely drag & drop the app in the .dmg window to the apps folder in the same window.

I think it's important to point out that developer websites are the uncontested first choice source for d/l's at FTM.
