Sub enclosure design tools

What software do you use when building an enclosure for subs? I am on a Mac, if it opens up choices.

I have a copy of Bassbox 6 pro running in a VM that kinda works. After designing the box I transfer the pieces to https://www.cutlistoptimizer.com/ to get a cutlist.

I also tried https://subbox.pro/, works good but has no response curve functionality.

I've been using Term-Pro for years.

That looks pretty nice. Bassbox pro 6 is very buggy and dated.

Using Bassbox Pro myself and it works well.
