I tried to do that but a lot of the tests are doing increment/decrement multiple times and then check the value. That would require us to put tons of setTimeout in the tests and make them less readable.

Another concern is that this is only Mac but some tests are for all platforms so it's not reasonable to make them wait.

I think the core is not changed just the timing might be affected on macOS, so maybe keeping the sync version is not a bad idea?
