BTW, so far no issues with Laravel 7. I did notice it worked on 1 computer and not another. This was just an issue with updating the PHP. Had some difficulties downloading spark but that was solved easily by doing a git clone. Other than that, there are a lot of issues with Catalina. My issues were solved by updating my paths for Composer, Laravel, and Spark.
The biggest thing so far with Laravel 7 was the auth scaffolding. Easily solved by looking at the Laravel 7 documentation.
