I don't have current information about Claude Code's updates or specific claims about Mac minis being "killed" by a computer control feature. My knowledge was last updated in April 2024, so I can't verify recent announcements or discussions.

However, I can offer some context:

If there are concerns about Mac minis specifically, possible reasons people might cite could include:
- **Hardware limitations** - Mac minis might struggle with the resource demands of continuous computer control features
- **Thermal issues** - Running control features constantly could cause overheating
- **Performance degradation** - The feature might be more resource-intensive than expected on lower-end hardware

That said, your experience with Mac Studio seems positive, which suggests the feature itself works well on higher-capacity hardware.

For accurate, current information about this issue, I'd recommend:
- Checking recent tech news sites or Reddit discussions
- Looking at Anthropic's official announcements
- Reviewing Mac mini user forums for actual performance reports

Could you share more details about what specifically people are claiming, or point me toward the discussion you're referencing?
