Question
Installation fails on Mac
I had the same issue with the December update to FlashPlayer. It does not install and the workaround is to install and earlier version and disable security protection. Consequently, unless I really need FlashPlayer, it is always disabled.
Device: Mac Pro early 2009
OS: OS x 10.11.6
Safari: Version 11.0.3
When problem reported in December, Adobe staff thanked me for the bug report but evidently they have either not tried or not succeeded in fixing the bug.
