Question
Mac OS X Flash installer freezes at 90%.
The Mac is on version 10.11.4 of OS X. I'm using Safari. I can download new version 21.0.0.213, double-click, get prompted for password and install starts, but progress bar gets stuck at 90%, then after a while quits with failure. I've already tried downloading the offline installer from the Mac troubleshooting guide and the issue persists.
