About a week ago, Apple issued macOS 10.14.6, however, the company has already launched a Supplemental Update. The update, which was released yesterday, addresses an issue preventing certain Macs from waking up from sleep properly.
According to the problem description, it appears that some Macs have failed to wake up after going into sleep mode. However, since yesterday, Apple claims that after installing the Supplemental Update, this issue should be fully solved:
“The macOS Mojave 10.14.6 Supplemental Update fixes an issue that may prevent certain Macs from waking from sleep properly.”
Usually, every time Apple launches an OS update, the company updates its security page with details about security changes and fixes which it chooses to disclose. However, there’s no entry for that yet.
In fact, the only entry on the security update tracker for yesterday was related to iCloud for Windows 10.6.1. but even that “has no published CVE entries.”
macOS 10.14.6 was released together with iOS 12.4 on July 22, 2019. The update included an innovation of the Apple News+ features and fixed some bugs, as well as an issue with Boot Camp on Fusion Drives, black screens on the Mac mini, graphics problems which occurred after waking some Macs from sleep, and “an issue that may cause a hang during a restart.”
Considering the previous Apple release schedules, most probably there won’t be any more major updates to macOS before the release of macOS 10.15 Catalina expected this fall.
