The crash happens opening the application alone. There is no .blend file being loaded.

Understand we can't do much unless we can reproduce this issue.

According to crash log blender crashed on:

tbb::interface7::internal::task_arena_base::internal_max_concurrency(tbb::interface7::task_arena const*) + 50

tbb was only added recently to blender I think in quad remesher.

Some other things to try.

  1. Try a recent nightly build from here.
  2. Try starting blender with --factory-startup from the console.
  3. You don't say in your report if 2.80 crashes or not?

I can confirm that the 2.82 alpha also crashes in relation to TBB. 2.80 runs as intended.

Works fine on my MBP, both 2.81 and latest master builds from

@Sebastián Barschkis (sebbas) or @William Reynish (billreynish) should be able to test relatively easily as well.

Both the latest master and 2.81 do not give me a startup crash either on macOS.
