Mac OS X

Along with macOS High Sierra 10.13.3, Apple this morning released two new security updates that are designed to address the Meltdown and Spectre vulnerabilities on machines that continue to run macOS Sierra and OS X El Capitan.

As outlined in Apple's security support document, Security Update 2018-001 available for macOS Sierra 10.12.6 and OS X El Capitan 10.11.6 offers several mitigations for both Meltdown and Spectre, along with fixes for other security issues, and the updates should be installed immediately.

Together with last week's update, this means the last three major revisions of macOS are now protected from the processor bugs.

Update increased my boot time by 4 seconds

Initially it more than doubled my boot time and I thought here we go back to the bad old days of 30+ second boots, but an nvram reset has it booting a mere 4 seconds slower than preupdate. Even so, if linux can manage 7 seconds why do I have to wait 16 on my iMac?
