Potential instant 20-50% computer speedup - open terminal - type "arch" Discovered today that my computer had been running most things ~30% slower for years. In 2020 @Apple switched Macs from Intel chips to their own ARM chips (M1, M2, M3, M4). To make sure old Intel apps didn't break overnight, they built Rosetta — a translation layer that converts Intel instructions to ARM on the fly. It works so well you don't even know it's there. That's the problem. When I migrated from my old Intel Mac, Migration Assistant silently copied over Intel @MacHomebrew. From that point on, every single package I installed — Node, Python, my terminal, 200+ developer tools — was the Intel version. Rosetta translated everything seamlessly. No warnings. No errors. Just 30% slower across the board, and I had no idea. I only caught it this weekend because I was doing a fresh install of @openclaw to test a secret project I'm building. The new update of Openclaw uses node-llama-cpp, which flat out refuses to run under Rosetta. That one failure exposed years of hidden performance loss. This might be happening to you. To check 1. Open http:/Terminal.app (the default macOS terminal, not a third-party one) 2. Type "arch" and hit enter 3. If it says arm64 — you're good, everything is running native 4. If it says i386 — your Mac is running everything through Rosetta and you're leaving 20-50% performance on the table You can also check specific apps: right-click any app → Get Info → if "Open using Rosetta" is checked (or greyed out), it's running translated. To Fix 1. Open http:/Terminal.app (not a third-party terminal — it might also be running under Rosetta) 2. Install ARM Homebrew: /bin/bash -c "$(curl -fsSL raw.githubusercontent.com/Home...…)" 3. Reinstall your packages using /opt/homebrew/bin/brew Go check right now. ⚡️ Godspeed.
