My mac had a black screen saying Error 14 while making software updates from App Store
App Store notified me about software updates, so I did. At first it said "installing" just as usual but later it turned to a black screen like below:
Although it had restarted normally now, I'm worried if there's any security problem associated with my mac since my credit card information was stolen yesterday...
Thanks!
