Offline AI on macOS without cloud logins
Mac users can run offline AI without installing runtimes or using cloud accounts. PortableMind includes a macOS launcher, models, and presets on a USB.
macOS launcher with no installs or cloud calls.
Works on Intel and Apple silicon.
Covers Gatekeeper approvals and offline proof.
Who this is for / not for
For macOS users who want offline AI with no accounts. Not for those committed to cloud-native macOS apps that require internet access.
- Good fit for travelers and privacy-focused Mac owners.
- Skip if you need real-time cloud collaboration features.
Specs that actually matter
macOS 13+, 8–16 GB RAM, and a USB 3.0/USB-C port. Apple silicon and modern Intel chips both work. GPU not required.
- Keep 4–6 GB free disk space.
- Allow the launcher in Gatekeeper once.
- Balanced preset shines on 16 GB+ machines.
Launch on macOS cleanly
Open the USB, run Start-PortableMind.command, and approve in Privacy & Security. Bookmark localhost. Run in airplane mode to confirm offline behavior.
- If Open Anyway appears, approve once, then rerun.
- Use the fast preset on fanless MacBooks to keep temps down.
- Store prompts in a folder on the USB for portability.
Common pitfalls
Trying to launch directly from Finder without granting execute permission. Letting iCloud Drive sync outputs. Expecting GPU acceleration.
- Use Terminal if double-click is blocked; instructions are in /howto.
- Pause iCloud during sensitive sessions.
- Stay plugged in for longer balanced runs.
PortableMind vs DIY
DIY on macOS means Homebrew, CLI installs, and model downloads. PortableMind skips that—models and UI are already packaged on the USB.
- No brew installs or curl scripts.
- Consistent across Intel and Apple silicon.
Keep it smooth on macOS
Keep a small backup of the USB. Clear caches occasionally. If you rotate between devices, ensure each has the launcher approved so you’re not blocked while traveling.
- Test once in airplane mode on each Mac you use.
- Back up prompt packs to encrypted storage.
- Avoid updating during travel days.
