Related to discussion starting from [this comment](https://github.com/pandas-dev/pandas/issues/38921#issuecomment-1586318796) on #38921. The test fails on with the Mac M2 chip, so this PR removes the exclusion of Mac from the xfail marker. Mac was previously excluded because the test passes on M1.
All checks passed. Now just waiting on review. Please let me know if any changes need to be made. This test is not passing on my M1 Macbook Pro. I think we should skip it for all arm chip Mac for now.  > This test is not passing on my M1 Macbook Pro. I think we should skip it for all arm chip Mac for now.
