Safari 10.0 update stalled on iMac running El Capitan. Been here about 45 minutes. What now?
Downloaded Safari 10.0 update on iMac 2012 with 1 Tb HDD & 16Gb Ram. System rebooted & started to do the install & stalled about 2/3 of the way thru (based on the progress bar). Been sitting there for about 45 minutes. What can I do to get it moving or get out of it?
iMac (21.5-inch, Late 2012), OS X El Capitan (10.11.6), 1Tb HDD + 16 Gb Ram
