Some Mac owners today faced error messages or applications that balked when launched in a repeat of the November 2015 expired-digital-certificate issue.
Three months ago, a lapsed Apple-issued certificate triggered a fiasco that prevented Mac users from running software they’d purchased from the Mac App Store.
“Some of my Mac apps won’t open today. I know why, and I know a re-install fixes it … but … sigh. Mac App Store: It Just Works* (*sometimes),” tweeted Russell Ivanovic, a mobile app developer at Shifty Jelly.
