Regression Test Fails on Postgres v12

I am trying to install AGE on my system running macOS 12.6.3 with PostgreSQL REL_12_STABLE. I am using the AGE_PG12.1.0_ALPHA branch for the installation. After running the install command, I've done the regression tests using installcheck, which tells me that 2 tests have failed and that that there is an error. I understand that the error is not a big deal as it is just due to the return value of string comparisons on macOS being different, but am not sure about the failed tests. Are they significant and is there a way to fix them?

Here are the series of Terminal lines:

They are not very significant. You can ignore them for now as the official tutorial ignored when running the regression test in mac.

Hopefully in new release this will be fixed.
