Acrobat Reader won't install on OS Sierra
I'm trying to install Acrobat Reader on OS Sierra. I have OS Sierra 10.12.4 on an iMac 27 Retina purchase last month. The download process is no problem. However; when I try to install, the progress bar quickly goes to about 65% and stall. It says "Installing Package Scripts". After several minutes the fan on the computer come on full and almost everything hangs. Force quitting the the installation app appears to work but the fans remain on full and the system remains mostly unresponsive. The only way the stop this is to do a hard reboot with the power button.
I've read that it could be caused by not having the root user enabled but the the same thing happens even when the root user is enabled.
