Portal's portals are filled with some matter when running the game on my G96. Running on my MCP79 is fine.
Trace available at:
Verified to render correctly on i965 haswell. Would be nice if someone else with a G96 or older card can verify it also renders wrong. Otherwise it's an issue on the macbook gpu setup.

saturate shader test
On each of your NV96 and NVAC, please run the attached test through shader_runner. Also remove the "+ arg2" from the result computation and run it again. I suspect that only NV96 + arg2 removed will fail.
[The results that *actually* test clamping are 16, 20, 28, and 36.]
Looks like I was right in my guess. Since NVAC tends to have the same things as NVA0, I'm assuming that FMUL.SAT becomes a thing on G200+. Fix pushed:

nv50/ir: only enable mul saturate on G200+
Commit 44673512a84 enabled support for saturating fmul. However
experimentally this does not seem to work on the older chips. Restrict
the feature to G200 (NVA0) and later.
