Mac Mini M4 Ima Kau M5 Pro Matsu Isogi Project Guide (2026). 3つの落とし穴 / 意思決定マトリクス / 5手順.
01 3つの落とし穴
1. Peak scores, wrong job mix. Preview, encode, local models and CI stress RAM and disk differently.
2. Waiting for delivery as a plan. Certificates and OS trains slip. Validate on a rented node first.
3. Shared boxes for release. Signing and regression need isolation. Dedicated Apple Silicon is easier to audit.
02 意思決定マトリクス
| 観点 | 即購入 | 待つ | リモートレンタル | 行動 |
|---|---|---|---|---|
| Ship date risk | Only if in stock | High | Same-day | Rent first |
| RAM / disk fit | Must guess once | Unknown | Swap 16/24GB | Benchmark |
| Signing isolation | Local control | Unknown | Dedicated | No shared release |
| Peak-only load | Expensive if idle | Waste | Burst by day | Count build hours |
| Remote access | DIY ports | None | SSH/VNC ready | See help |
03 5手順
- Write the job mix and concurrency.
- Set pass/fail thresholds (compile, preview, disk headroom).
- Rent a dedicated node and log in via SSH/VNC.
- Run the same repo and Xcode train; do not change the environment mid-test.
- Decide with the matrix: buy if green, keep renting for peaks.
04 引用できる数値
- Track cold compile, recoverable memory pressure, and >20% free disk.
- Do not ship from a shared machine.
- Remote nodes: same-day, resizable, SSH/VNC.
