Sep 19, 2016 The problem you are not able to install Adoble Flash PLayer on macOS Sierra is because of SIP (System Integrity Protection) which is preventing the app to write on the directory /var/folders/. To solve this you have to enter Recovery Mode of Mac. Following Google's footsteps, Apple has announced it will block Adobe Flash Player plugin in its new Safari browser that will be shipped alongside macOS Sierra. /2010-mac-for-sale.html.
Follow up on my prior note explaining a useful remedy to the Flash Player issue. Following the aforementioned procedure the subsequent files were added in ‘MacIntosh HD/Collection/Internet/PepperFlashPlayer'. ln the PepperFlashPlayer foIder are usually express.json (the script for PFP) ánd PepperFlashPlayer.plugin. Thé afterwards contains the port line ‘ HDP-MacBook-Pró-1201:PepperFlashPlayer.plugin hportnoy$'. I'meters operating on El Capitan (v 10.11.6). Hope this assists out the experts in finding a better solution. Anthony Laforge (Google) 8/9/2016, 21:17 น.
