Additional mitigations for speculative execution vulnerabilities in Intel CPUs
"- Apple has released security updates in macOS Mojave 10.14.5 to protect against speculative execution vulnerabilities in Intel CPUs...
- macOS Mojave 10.14.5 includes security updates for Safari, and the option to enable full mitigation...(see article below)
- Security Update 2019-003 High Sierra and Security Update 2019-003 Sierra include the option to enable full mitigation."
(The article also lists "Unsupported Mac models" (2009-2010 MacBook, MacBook Air, MacBook Pro, iMac, Mac mini, Mac Pro) that may be able to install security updates, but are "unable to support the fixes and mitigations due to a lack of microcode updates from Intel".)
"Testing conducted by Apple in May 2019 showed as much as a 40 percent reduction in performance with tests that include multithreaded workloads and public benchmarks. Performance tests are conducted using specific Mac computers. Actual results will vary based on model, configuration, usage, and other factors."
As before, some have had problems installing the Security Update. A tip was to try installing from a safe mode boot. (Hopefully there won't be a need for another (revised) update like they did with Security Update 2019-002.)
(Again Apple released macOS and iOS/tvOS/watchOS updates simultaneously so servers may be swamped initially.)
FYI on Nvidia Web Driver Updates:
(There's been no Mojave Nvidia web driver updates yet, but a reminder to 10.13.6/10.12.6 users of Nvidia's web graphics drivers.)
New OS updates or later build numbers after Security Updates typically break currently installed Nvidia web graphics drivers. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default OS X drivers.)
