This issue is Mac only. Windows is fine.

Steps:
1. Clone DOTS monorepo
2. Open Projects/HybridURPSamples
3. On ProjectView, select HybridURPSamplesBuildSettings
4. Set platform to macOS, click Apply, click Build and Run
5. Build failed with a lot of errors:

The instruction `Unity.Burst.Intrinsics.X86.Sse2.cmpeq_epi32(Unity.Burst.Intrinsics.v128 a, Unity.Burst.Intrinsics.v128 b)` requires CPU feature `SSE2` but the current block only supports `None` and the target CPU for this method is `ARM_AARCH64_ADVSIMD_AndLower`. Consider enclosing the usage of this instruction with an if test for the appropriate `IsXXXSupported` property.

The instruction `Unity.Burst.Intrinsics.X86.Sse.set1_ps(float a)` requires CPU feature `SSE` but the current block only supports `None` and the target CPU for this method is `ARM_AARCH64_ADVSIMD_AndLower`. Consider enclosing the usage of this instruction with an if test for the appropriate `IsXXXSupported` property.
