Hi, I'm running the last apprentice version on Yosemite 10.10.5 (AMD Radeon HD 6970M). I have attached a screenshot of my problem. When I try to select all the faces (primitives), the selection tool just selects a few. This only happens on:

Houdini 14.0.395 (PRODUCTION BUILD) and 14.0.432 - Houdini Apprentice
Using Polygon Mesh & Mesh (There is not any problem with Polygon) AND ONLY WITH QUADRILATERALS
Note: in some cases it crashes too after selection.

Now… this problem is not present in previous versions.

Any idea?

By the “M” at the end of your 6970M graphics card, I assume this is on a Macbook. A few months ago, we had to remove all mobile AMD GPUs from the list of supported graphics cards under OSX, due in part to this issue. We have submitted a bug to Apple concerning this issue, but don't know when they might be addressing it.

Yep, I have a mac with an AMD card - it's just really frustrating that in spite of SESI's bending over backwards to work around their crappy drive, Apple can't/won't update it.

If you are able to, try dual booting Windows, much better AMD support. I know Dual Booting isn't ideal, but Apple's not left much room here.

Thank you for your replies. It's an iMac, then I think there is not any solution for now. I will be using the apprentice previous version (it's just for learning). By the way, do you know if Houdini supports the nVidia Quadro K3100M?

Hi, I have noticed that Houdini 15 has solved this situation. However, I'm a little worried if I upgrade to El Capitan and get the same error? Should I be worried? Cheers.
