OpenCore Legacy Patcher v2.4.1 — Changelog & Download

What's new in OpenCore Legacy Patcher v2.4.1

• Installer source switched to AppleDB. Resolves a regression where the wrong macOS installer (or no installer at all) would appear when you used Create macOS Installer. AppleDB is a community-maintained, authenticated catalog of Apple's official installer assets.

That's the entire v2.4.1 delta. All other behaviour matches v2.4.0 — repeated below for reference.

Inherited from v2.4.0 (May 12, 2025)

• Apple Pay fix on T1 Macs running macOS 15.5. ApplePay-related processes were erroring out — resolved by the v2.4.0 root-patch changes.
• coreautha fix on T1 Macs (macOS 14.4 or later). Prevents authentication daemon crashes on first-generation Touch Bar models.
• USB-1.1 camera support on macOS Sequoia. Restores built-in cameras on Macs whose camera modules sit on a USB-1.1 bus (early Intel models).
• Lower CPU usage on the UI thread. The GUI no longer pegs a core when waiting on background tasks — meaningfully better on slower Macs.
• PatcherSupportPkg bumped to 1.9.5. The shared support binary set used by all root patches.

Upgrading from v2.4.0

Run the new v2.4.1 PKG over the top — it replaces the app cleanly. You do not need to re-build OpenCore or re-apply root patches just to take this point release.

Upgrading from v2.3.x or earlier

After installing v2.4.1, open the patcher and use Build and Install OpenCore to refresh your EFI, then reboot. If you're already on Sequoia, you usually do not need to re-apply post-install root patches — but check the in-app status panel; it will tell you if anything is out of date.

Sequoia is still in active development

As the Dortania team put it in the release notes: macOS Sequoia support on unsupported Macs is community-driven and still evolving. If a particular workflow on your model is unstable on 15.x, staying on Sonoma is a reasonable choice — OCLP fully supports older targets too.
