I had the same issues and this parameter in the Houdin.env fix the problem ---- for my point of view should be also nice to Understand Why we have to insert this command: what is the real root cause.
Thanks.

Houdini rarely officially supports Apple graphics cards that currently come with laptops and desktops. I learned this with purchasing a Mac Pro. If I were to do it over again, I wouldn't purchase Apple products for serious 3d work. Apple's phones and laptops are pretty reliable but I have had to replace almost everything for defects in my recent Mac Pro. At least it was under warranty.

I'm using osx with a lot of software including Houdini, Maya and C4d. ZERO ISSUEs

I've not so huge experience in 3D world but after playing for a long while whit C4D and Houdini I can say that if you open a huge C4D scene with a lot of objects, Xpresso rules, tags, and so on let me say that it is easier an equivalent complex scene in Houdini where following the path between the nodes you can understand better and faster. So, for me, Houdini is not more complex than other 3D applications. Somewhere I read that Houdini is just a fast and powerful tool that handles a huge matrix number (its spreadsheet) by applying mathematics rules. As well as all other 3D software. Fortunately, in Houdini this is visible/accessible and you can see it and use it also as a debugger or control.
I don't have issues using Vex (after spending years in C programming, vex is like a toy for me) but absolutely for me is crazy using Vop or any other tentative to replace programming with some horrible block logic.
The interface needs a refresh, for me, but because you can customize this is my last issue.
I'm trying to understand Solaris but let me say that it is not easy.
