Apple on Friday released a macOS Mojave Supplemental Update with fixes for bugs introduced by a prior security update, as well as a re-release of Safari 14 for the operating system.
Earlier in the week, Apple pulled the buggy macOS Mojave Security Update 2020-005 and Safari 14 for macOS Mojave after they were discovered to have caused problems for users who downloaded them. Issues included system sluggishness, slow boot times, high fan speeds, and memory problems.
The macOS Mojave 10.14.6 update released Friday should fix those issues for users who installed the Security Update 2020-005. Apple also re-released the Safari 14.0 update to macOS Mojave users, also presumably with bug fixes related to issues reported on the last release.
As Apple notes, it also introduces the security features that the buggy prior did.
The macOS Mojave Supplemental Update is available to download from the System Preferences menu.
