Apple previously released security updates to defend against Spectre—a series of speculative execution vulnerabilities affecting devices with ARM-based and Intel CPUs. Intel has disclosed additional Spectre vulnerabilities, called Microarchitectural Data Sampling (MDS), that apply to desktop and notebook computers with Intel CPUs, including all modern Mac computers.

macOS Mojave 10.14.5 includes security updates for Safari, and the option to enable full mitigation, as described below.

About security fixes in macOS Mojave

macOS Mojave 10.14.5 fixes this issue for Safari with no measurable performance impact.¹ This update prevents exploitation of these vulnerabilities via JavaScript or as a result of navigating to a malicious website in Safari.

Customers can also protect their Mac by updating security settings in macOS to download apps only from the App Store. This setting helps prevent the installation of apps that could potentially exploit these vulnerabilities. All apps from the App Store are signed by Apple to ensure that they haven’t been tampered with or altered. Learn how to view and change app security settings on your Mac.

Although there are no known exploits affecting customers at the time of this writing, customers with computers at heightened risk or who run untrusted software on their Mac can optionally enable full mitigation to prevent harmful apps from exploiting these vulnerabilities. Full mitigation requires using the Terminal app to enable an additional CPU instruction and disable hyper-threading processing technology. This capability is available for macOS Mojave, High Sierra, and Sierra in the latest security updates and may reduce performance by up to 40 percent², with the most impact on intensive computing tasks that are highly multithreaded. Learn how to enable full mitigation.

Unsupported Mac models

These Mac models may receive security updates in macOS Mojave, High Sierra or Sierra, but are unable to support the fixes and mitigations due to a lack of microcode updates from Intel.

¹ Safari performance: Testing conducted by Apple in May 2019 showed that these updates resulted in no measurable reduction in Safari performance using common Web browsing benchmarks such as Speedometer, JetStream, and MotionMark.

² macOS performance: Testing conducted by Apple in May 2019 showed as much as a 40% 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.

• Using APFS is REQUIRED in Mojave in order to receive system updates via the normal Software Update method. If you choose to continue using macOS Extended (Journaled) as your filesystem type, you will NOT receive System Updates via System Preferences. If you are not using APFS, you can follow the 10.14.1 installation steps below.


• After applying ANY system update via Software Update, re-applying post-install patches using your Mojave Patcher installer volume will most likely be necessary. If you install a software update and the system fails to boot afterwards, this is what needs to be done.

10.14.6 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.2 or later after installing.

10.14.5 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.1 or later after installing.

10.14.4 adds new changes that ARE NOT patchable by the post-install tool of Mojave Patcher v1.2.3 and older! Before updating to 10.14.4, you you will need to use the latest Mojave Patcher version to create a new installer volume, using the 10.14.4 installer app. Then, update to 10.14.4, either by installing via Software Update, or by just using the installer volume you've created to install.

If you are currently running 10.14.1 or 10.14.2, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.3 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, you'll need to proceed with the 10.14.1 update method described below.

If you are currently running 10.14.1, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.2 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, or are using a non-AFPS volume, you'll need to proceed with the 10.14.1 update method described below.

Mojave Not Supported Mac

• Download the latest version of Mojave Patcher
• Download the installer using the Tools menu of Mojave Patcher
• Create a patched USB installer
• Boot from that, and install 10.14.1 onto the volume containing an older release.
• Once done, apply the post-install patches, and you should now be on 10.14.1.
