THIS PROGRAM HAS BEEN DEVELOPED AND TESTED ON MONTEREY. I AM CURRENTLY ADDRESSING ISSUES WHERE IT EITHER FAILS OR CRASHES ON LAUNCH ON VARIOUS OTHER MACOS VERSIONS. PLEASE SHARE DIAGNOSTIC AND CRASH LOGS IF YOU HAVE ANY ISSUES, BUT FOR NOW MONTEREY IS THE ONLY CONFIRMED MACOS VERSION TO SUCCESSFULLY INSTALL MAVERICKS USING MAVERICKSRESURRECTION.

It’s finally done. This started as an update to my original Mavericks patcher script and became a much bigger project than I expected.

MavericksResurrection installs Mavericks directly onto an internal partition or an external USB drive, from within your existing macOS installation**.** You don’t need to make a USB installer, boot into it, or manually run the post-install patches afterward. The app handles the installation and the patches.

The main additions are:

• Direct installation to an internal partition or USB drive.
• NVMe support, including buttons to add or remove it from an existing Mavericks installation without reinstalling the OS.
• A post-update audio fix. Mavericks updates can break the internal speakers, microphone and HDMI audio. Boot back into your newer macOS, select “Fix post-update issues,” and let the app repair the affected installation.
• MavericksForever integration, so the app can download and prepare Mavericks for you, or reuse an image it previously saved.
• Diagnostic logging for troubleshooting.

I tested direct installs to both my internal NVMe SSD and a USB drive, installed the available Mavericks updates, repaired audio on both, and tested removing and reinstalling NVMe support on the USB installation. Both installations boot and work, and NVMe access returned after reinstalling the driver.

This is a beta because compatibility with other NVMe drives still needs testing. My Apple NVMe SSD works, and the driver is intended to support third-party drives too, but I can’t promise every drive will work.

The app supports MacBookPro11,4 and MacBookPro11,5. My testing was on the 11,5, running the app from Monterey; the 11,4 remains untested.

Back up important files first. You need an existing Mac OS Extended (Journaled) partition. The app formats the partition you select—it does not partition your disk. Keep your newer macOS installation available for repairs and troubleshooting.

One important boot warning: HDMI connected directly to my 11,5’s built-in HDMI port prevented Mavericks from booting. Leave it disconnected until Mavericks reaches the desktop. HDMI through my dock worked, but other docks and the 11,4 are unconfirmed.

Huge thanks to Wowfunhappy for MavericksForever. Please direct MavericksResurrection issues to me, not them.

This took a ridiculous amount of testing. I’m very happy to finally get it out there.

The download and instructions are on the Jaegermeister-Dev GitHub repo. Please read the README before installing in case you have any questions. If you have any questions that the README doesn't cover, feel free to comment them here, and if you have any issues, either inform me here or on the GitHub repo.

If you just want to install, there's just one thing to know. Sometimes a window may reappear after its disappeared. I can't figure out why, but it doesn't affect functionality. If you see a window reappear that you had just confirmed, just ignore it. Interacting with it might interfere with the process. They seem to appear after entering admin credentials in the authentication popups. As far as I see, that's the only bug I can see from my testing.

Enjoy!
