Ughh, almost two years from my last post. Seems topic is dead, but I write it anyway.
Today was released CCleaner for Mac v1.15 and there is one thing which is pay attention for me: "Fixed issue preventing CCleaner from running on macOS Snow Leopard (OS X 10.6)"
I still use 10.6.8 on my work and this string in changelog give me a hope. I install 1.15... but no luck. Just not running.
Like in previous message I roll back to 1.12 which work fine for me.
I understand that 10.6.8 is absolutely outdated but I use it for some reasons on my work.
