I just upgraded my late 2013 Mac Pro to El Capitan today (10.11.2). It seemed to install fine, but I cannot get it to launch--it just sits there with the spinning beachball of death. All I can do is Force Quit & then it wants to send an error report to Apple.
I uninstalled Toast 14, reinstalled it & rebooted but still no success. Is there an issue with Toast 14 running under the latest version/update of the Mac OS? Is there a fix in the works?
