I downloaded the update and double clicked on it and a small grey box appeared with f on it and a 2cm scroll bar on the top right corner. The download is called InstallOS.dmg and is 5.01gb and going to take over 2 hours.
Is there a technical issue here and is this InstallOS.dmg for Adobe as I had some issues with a website before and I am concerned this download might not be Adoble. What is the download called.
Your suggestions to fix this appreciated.
That's not a Flash Player installer file. Flash Player installer file is not named InstallOS.dmg and it's around 25-30 MB is size. Certainly not 5.01 GB.
Is it from get.adobe.com
I just tried it again and this time the download is AdobeFlashPlayer...2_ast_install.dmg and is 804kb but the same grey box appears and the scroll bar does not move
AdobeFlashPlayer_32_ast_install.dmg is the online shim installer the downloads and installs Flash Player silently in the background, which is why this file is only 804kB.
Is this the grey box that the scroll bar doesn't move that you're seeing?
If so, I'm not sure why it's hanging.
Can you try the offline (full) installer posted at the bottom of the https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-mac.html page in the 'Still having problems' section?
