I don't have current information about Claude Code updates or recent controversies regarding Mac mini compatibility, as my knowledge was last updated in April 2024 and I can't browse the internet for current events.

However, I can clarify a few things:

1. **I'm Claude, made by Anthropic** - not "Claude Code." There may be confusion about product names or features.

2. **If this is about a computer control feature**, any widespread compatibility issues would likely stem from:
- Resource demands (M-series Macs have different performance tiers)
- Driver or OS compatibility problems
- Conflicts with Mac mini's specific architecture

3. **Your Mac Studio situation** - If you prefer using a more powerful machine to avoid keeping your MacBook running constantly, that's a valid approach for reducing power consumption.

To get accurate information about the specific update you're asking about, I'd recommend:
- Checking official Anthropic announcements
- Looking at Mac mini user forums or subreddits
- Reviewing the feature's system requirements

Could you provide more details about what specific feature or update you're referring to? That would help me give you more useful context.
