It was just over a week ago that Apple released macOS 10.14.6, but the company has already squeezed out an Additional Update . Published today, the update resolves a hitherto unknown issue involving hibernation on Macs.
It looks like some Macs haven't been able to wake up after going to sleep. The update does not appear to change much else. Apple's complete notes are as follows:
MacOS Mojave 10.14.6 Additional Update fixes an issue that may prevent certain Macs from waking up properly from sleep.
has seen some posts from users who claim that they have had this problem and hope this update fixes it.
When Apple releases an OS update, it typically updates the security page with information about security changes and fixes it chooses to reveal. But there are no entries for it today – the only entry for security update tracking for today is for iCloud for Windows 10.6.1. But even it "has no published CVE listings."
macOS 10.14.6 released with iOS 12.4 July 22. It added a host of Apple News + features and fixed a number of bugs, including a problem with Boot Camp on Fusion drives, black screens on the Mac mini, graphics issues that occurred after waking some Macs from sleep, and "a problem that can cause a hang during a reboot. "
Based on previous Apple release plans, it is unlikely that we will see several major updates to macOS before the latest annual release, macOS 10.15 Catalina, rolls out later this year. Catalina's flagship feature is the ability to run apps originally developed for the iPad, with only relatively minor adjustments that app developers require in some cases. It will also split iTunes into several apps such as Music, Podcasts and TV.
Catalina is expected to launch on both new and old Macs this fall.
