    • If you need IL2CPP, add this to your scripts: 
      #if UNITY_EDITOR && UNITY_2026_2_OR_NEWER
[Unity.Burst.BurstCompile(DisableOnAppleSilicon = true)]
#endif

  4. Test Play Mode:

    • Enter Play Mode
    • Should work without Burst-related crashes

Note: This is a temporary workaround. Burst support for Apple Silicon improves with each beta update.

Verification: Play Mode should work with Burst disabled.

Solution 4: Fix Memory and Graphics Settings

Apple Silicon Macs have unified memory architecture that requires different settings.

Memory Optimization:

  1. Increase Unity Memory Limit:

    • Open Edit > Preferences (macOS: Unity > Preferences)
    • Go to "General" tab
    • Increase "Memory Limit" if available
    • Or set to "Unlimited" for testing

  2. Close Other Applications:

    • Quit unnecessary apps
    • Free up RAM before testing Play Mode
    • Apple Silicon shares memory between CPU and GPU

Graphics Settings:

  1. Open Project Settings:

    • Edit > Project Settings > Graphics

  2. Adjust Graphics API:

    • Ensure Metal is selected (default on macOS)
    • Don't use OpenGL or Vulkan on Apple Silicon

  3. Lower Graphics Quality (For Testing):

    • Edit > Project Settings > Quality
    • Set to "Very Low" or "Low" temporarily
    • Test if Play Mode works with lower settings

Verification: Play Mode should work with optimized memory and graphics settings.

Solution 5: Clear Library and Temp Folders

Corrupted cache files can cause Play Mode crashes on Apple Silicon.

Steps:
