I was not aware of any of those problems. And I played the Mac version. When I had an Xbox, I spent a lot of time looking at textures up close cause the quality was amazing to me. Once I played it on the Mac I instantly noticed how much cleaner and sharper everything was.
It was released during the PowerPC era, and the internet says it works on Intel Mac through Rosetta emulation. That might result in the graphical issues you mentioned. Having to run through Rosetta means Microsoft (or Macport) never issued a patch for native Intel compatibility.
I was wrong about it being Mac exclusive. I though the Windows PC version was a straight port from Xbox, but it’s the same “enhanced” version of the game that Macs got.

Apple had a handshake deal with Bungie, until Microsoft bought Bungie and made the Mac exclusive an Xbox exclusive.
It came full circle when Halo CE SE was released as a Mac exclusive on Mac & PC. And it is arguably the best version of the original game on any platform (higher resolution textures without a complete remake, exclusive multiplayer weapons, etc.).

she pinned an elite into a wall with a Banshee and fired on them for a solid minute
In the original Halo on Xbox, I found out that if you keep meleeing a dead elite, the blood splatter keeps getting reapplied to the ground around it, and the existing splatter never despawns. Do this for a minute and you can bring the frame rate of the game down to a single-digit-number.
To the game’s credit, it doesn’t crash or stop responding, it just keeps skipping frames to make up for the excessive graphics processor use. And if you turn away from the blood, the frame rate returns to normal. But your “paint job” remains in memory as long as you are on that level. As soon as you look at it again, the frame rate drops again.

Reminds me how you can effectively nullify all the secret agents in Evil Genius by building dozens of huts outside with locked doors that lead to dead end hallways rigged with pop-up dummies.
The fact that there’s a locked door entices them to waste time cracking it open. Once inside, they get jumped by a dummy and shoot it then become confused because it’s not real. Eventually they get so confused they leave the hut. They the AI’s pathfinding sees the same damn door which has locked itself again. Wash, rinse repeat.
Sometimes they get mad and start shooting the traps until they explode, which injures them and convinces them to just go home. Once they leave, rebuild the damaged hut and wait for the next secret agent.
Did golden light pour out of the box when you opened it?
