2026-05-23 Google Antigravity on a leased Mac mini M4 (HK / JP / KR / SG / US)

Google Antigravity is an agent-first development platform—IDE, Agent Manager, browser agent, and Antigravity CLI—that Google positioned at I/O 2026 as the successor path for terminal workflows previously served by Gemini CLI. Teams already renting Mac mini M4 builders in Hong Kong, Tokyo, Seoul, Singapore, and the US can run Antigravity beside Xcode 16 and agents such as Codex CLI and Claude Code, but only if you respect Apple Silicon-only installers, RAM ceilings, and SSH headless limits.

What Google Antigravity is in 2026

Antigravity 2.0 (May 2026) bundles the Antigravity IDE (VS Code–familiar editor with asynchronous agents), Agent Manager (dispatch and monitor multiple agents with artifacts and verification tests), Antigravity CLI (terminal agent sharing the desktop harness), and a browser agent (Chrome-dependent verification loops—not available headless over pure SSH).

Google states Antigravity CLI replaces Gemini CLI for individual and Pro/Ultra users, with a June 18, 2026 cutoff for Gemini CLI requests on consumer plans. Enterprise Gemini CLI support continues on a separate timeline per Google's enterprise docs. Install surfaces: Antigravity download (DMG for macOS) and curl -fsSL https://antigravity.google/cli/install.sh | bash for CLI on macOS/Linux.

Why run Antigravity on a leased M4 Mac

Apple's Mac mini specifications list Apple Silicon only for current generations—aligned with Google's macOS requirement (Monterey 12+, x86 not supported on recent Antigravity builds).

If capital expense is uncertain, start with the Mac mini M4 rent vs buy TCO framework before pinning five parallel agents on one host.

Antigravity IDE vs CLI on SSH builders

Compare terminal agents in our Codex CLI vs Claude Code M4 benchmark when choosing secondary tools—Antigravity is Google's stack; Codex/Claude remain strong for model-specific strengths.

Install matrix on Apple Silicon M4

IDE (DMG)

1. Download macOS Apple Silicon build from antigravity.google/download
2. Install to /Applications; first launch completes Google sign-in
3. Enable Secure Mode and terminal allow/deny lists before unattended agents

CLI (SSH-friendly)

curl -fsSL https://antigravity.google/cli/install.sh | bash

Verify the same PATH in launchd jobs and interactive SSH (pattern from OpenClaw onboard on headless leases).

Minimum practical RAM: Google cites 8 GB; 16 GB M4 is realistic for 2–3 concurrent agents plus light xcodebuild; 24 GB if you run five parallel agents and simulators.

Headless SSH and CI coexistence

Pure SSH sessions can run Antigravity CLI but cannot drive browser agent or IDE Agent Manager without a graphical session. For GUI bursts, use SSH vs VNC for Xcode on cloud Mac—schedule VNC only for verification windows, not 24/7.

• Separate state: ~/.antigravity vs ~/.codex vs ~/.claude vs ~/Library/Developer/Xcode/DerivedData
• Cap concurrent agents when xcodebuild lanes are hot
• Wire self-hosted GitHub Actions runners to invoke CLI in non-interactive mode with explicit working directories

When parallel xcodebuild lanes are hot, cap concurrent Antigravity agents.

Gemini CLI → Antigravity CLI migration

1. Export scripts using gemini CLI; map to antigravity entrypoints per Google migration notes
2. Re-pin MCP servers and allowlists
3. Re-test sandbox: macOS sandbox reduces destructive file ops but is not a substitute for lease path allowlists
4. Update CI secrets for Google account rotation independent of MacXCode SSH keys

Decision matrix: when Antigravity wins on leased M4

Eight-step rollout on leased Apple Silicon

1. Inventory workloads: IDE-only vs CLI-only vs CI-only
2. Provision one M4 lease in the API region closest to developers
3. Install CLI via curl installer; pin version in runbook
4. Configure Secure Mode, command allowlists, separate HOME for automation user
5. Dry-run a repo task; compare output to prior Gemini CLI baseline
6. Integrate self-hosted runner labels; never share API tokens across tenants
7. Schedule migration before June 18, 2026 for consumer Gemini CLI dependencies
8. Review monthly: agent count vs RAM, NVMe growth under ~/.antigravity, Xcode DerivedData janitor

FAQ

Why MacXCode for Antigravity + Xcode fleets

Leasing gives you regional Apple Silicon, reinstall hygiene, and static egress for Google API sessions without buying hardware per engineer. MacXCode Mac mini M4 nodes in HK / JP / KR / SG / US keep Antigravity state colocated with the same hosts running iOS CI.

Bottom line: treat Antigravity CLI as the SSH-first surface on leased M4, migrate before June 18, 2026, and isolate agent state from Xcode CI—lease regional builders instead of stacking five agents on a sleeping laptop.
