This morning, I started the upgrade to 11.3.1. After downloading the update, my computer alerted me it would restart in 60 seconds. But when I switched to System Preferences to select the Restart Now link, VoiceOver navigation seemed to be disabled. I could switch to other appsand use them normally, but System Preferences seemed to be frozen and would not let me navigate to the Restart Now button. I had no choice but to wait out the 60 seconds and let the system restart automatically.
Anyone else see this?
