0.5.2

This release of OpenCore Legacy Patcher 0.5.2 is primarily a bug fix release. Main fixes implemented include:

• Alleviates mediaanalysisd kernel panics on prolonged sleep
• Alleviates AMD Polaris display output support
• Work-around Apple's Developer Portal block on OCLP

And other miscellaneous fixes and improvements listed in the full changelog.

---

Other machines such as 2008-2012 Mac Pros and non-Metal Graphics Card machines are still in active development. We'd appreciate your patience as we work through these issues. Stay on macOS Monterey until the Patcher has been updated to support your model.

• Installing macOS Ventura on older models will likely result in lack of Graphics Acceleration, broken USB 1.1, Keyboard, TrackPad and Bluetooth and other issues. Zero support is offered for those systems at this time.

For machines with legacy Metal Graphics Cards, we'd recommend checking out macOS Ventura and OpenCore Legacy Patcher Support #1008 for overall support with these cards.

Reminder: Ventura support in 0.5.2 is in Beta, stay on Monterey for proper support

With Apple's release on macOS Monterey 12.6, we wanted to release some fixes associated with this OS. Main one is WebKit support with Safari 16.0 on Ivy Bridge iGPUs and non-Metal GPUs.

• If you've installed/updated to 12.6, Safari 16.0 will be an additional update separate from the OS (12.6 comes with Safari 15.6.1 by default). If you find Google text elements not rendering correctly, re-run the root volume patcher. See images below for symptoms

Otherwise we hope everyone enjoys the new release!

Missing WebKit Patch	WebKit Patch installed

• WebGL note: If you notice Google Maps in Safari is broken on Ivy Bridge and Haswell, know that this is an Apple bug resolved in Safari Tech Preview 16.1
  • Alternatively, disable "WebGL via Metal" in Safari's Developer Settings if you're on Safari 16.0

Affected Models (stock):

• MacBookPro9,1
• MacBookPro10,1
• MacBookPro11,3
• iMac13,x (units with dGPUs)
• iMac14,x (units with dGPUs)

Affected Models (user upgraded):

• iMac11,x (units with upgraded Kepler GPUs)
• iMac12,x (units with upgraded Kepler GPUs)
• MacPro3,1 (units with upgraded Kepler GPUs)
• MacPro4,1 (units with upgraded Kepler GPUs)

0.4.7

This release is a simple bug fix, see 0.4.6's release notes for previous changes and noteworthy updates:

---

With the initial developer beta of macOS Ventura, we've seen many drastic changes to the patcher process that creates many challenges for us. Thus we've decided to do this release which prioritizes Monterey support, before trying to tackle larger issues.

This release will not have any support for Ventura, and we don't expect to have public support for some time. See macOS Ventura and OpenCore Legacy Patcher Support for more info.

0.4.6

With the initial developer beta of macOS Ventura, we've seen many drastic changes to the patcher process that creates many challenges for us. Thus we've decided to do a release of 0.4.6 which prioritizes Monterey support, before trying to tackle larger issues.

This release will not have any support for Ventura, and we don't expect to have public support for some time. See macOS Ventura and OpenCore Legacy Patcher Support for more info.

Regarding note worthy features of this release:

• Resolve Bluetooth 2.1 support in macOS 12.4
• Greatly speed up GUI load times
• Resolve Zlib kernel panics on 12.4 with pre-Sandy Bridge CPUs
• Early support for Nvidia Web Drivers in non-Metal mode

Finally, this will be the final release where TUI binaries are uploaded on release. We have no plans to kill the TUI outright, but no effort will be made to maintain it. Developers can still compile TUIs from source, regular end users should transition to the GUI.

Otherwise, we hope everyone enjoys the new release!
