Fixed: macOS Hardware Acceleration Bug on M2 Ultra Mac Pro

Solutions

Since its release, the M2 Ultra Mac Pro has been praised for its power and efficiency. However, many users who upgraded to macOS Ventura have reported system-wide hardware acceleration issues, causing performance drops and software instability. Despite multiple reports, Apple has yet to officially acknowledge or address the problem.

Solution 1: Update macOS

Go to System Settings > General > Software Update and check for updates.
Install the latest version of macOS, as Apple may release patches to address hardware acceleration issues.

Solution 2 : Reset NVRAM and SMC

Reset NVRAM: Shut down your Mac, then restart while holding Option + Command + P + R for about 20 seconds.
Reset SMC: Depending on your Mac model, follow Apple’s official guide to reset the System Management Controller (SMC).

Solution 3 : Test in Safe Mode

Restart your Mac while holding the Shift key.
Safe Mode disables third-party extensions and performs system diagnostics. If the issue disappears, a third-party app may be causing conflicts.

Solution 4 : Disable Hardware Acceleration in Apps

Some applications (like Chrome, Final Cut Pro, and Adobe Premiere Pro) allow users to disable hardware acceleration in their settings.
