[Mesa-users] Encountering Errors Building MESA 24.08.01 in Mac OSX (Intel) ver. 15.5 (Sequoia).

Sun Jun 8 08:03:24 UTC 2025

Hi Sam,

Thanks for reaching out!

First, please grab the official release version from zenodo:
https://zenodo.org/records/13353788

The next thing to try would be to make sure we use the MESA sdk version of
gfortran.

The issue is your PATH has other things loading with higher priority than
MESA sdk. (since there are some items in your path prior to
/Applications/mesasdk/bin:)

You can either move the line

```
source $MESASDK_ROOT/bin/mesasdk_init.sh
```

in your .bashrc / .zshrc file down to the bottom, or you can just copy and
paste it into the command line. That will update the path.

Then in the MESA directory do a
./clean
./install

and see if that changes anything

Best,
Philip
