Yesterday I wanted to upgrade my Mac to the newest macOS, macOS Sierra. After the update, my Mac restarted, however, the computer booted to a black screen. The dark screen had an active white cursor. This article explains how I fixed this problem.
I was investigating this issue and I realized that many users were having this problem. Some of our readers stated that they experienced this issue with their Macs unexpectedly. Some users have also stated that they found their Mac like this in the morning after waking the computer from sleep or standby mode. How to download google sketchup free for mac.
So it seems that even though my Mac went into a black screen after an upgrade that fails to successfully update; however it also looks like the Mac computers may stop working unexpectedly and display only a black screen.
I have a MacBook Pro 15' (mid 2014, running Sierra). Recently, it has started black screening and shutting off shortly after, after a few minutes' use—let's say 3 to 10 minutes. The screen will go black but the LCD backlight will remain on for about 5 seconds, then the laptop will completely shut.

Normally, if you want to close all of the open apps on your Mac, you'd have to either quit them all one by one or restart, shut down, or log out while making sure to deselect “Reopen windows when logging back in.' The latter option is great, but it doesn't always work in Mac OS X, and what if you don't want to restart, shut down, or log out? Civilization 4 mac os download.
