⌘ + Space(Command key + Spacebar). A search box appears in the middle of the screen. - Type
Terminaland pressEnter.

-
Press
⌘ + Vto paste. -

Step 3 — Answer the prompts
The installer is chatty — it explains what it’s doing at each step. You’ll see coloured text like:🔍 Checking Homebrew...— it’s checking if you have a package manager called Homebrew. If not, it asks permission to install it.📦 Checking Node.js...— same for Node.js.🤖 Installing FideliOS CLI...— the main install.🚀 Starting FideliOS setup…— the final wizard.
y then Enter to say yes. Or press Enter alone to accept the default (which is almost always what you want).
If it asks for your password, type it in and press Enter. It won’t show dots or asterisks — the cursor just stays still. That’s normal. Finish typing and press Enter.
Step 4 — Open FideliOS in your browser
When the installer finishes you’ll see:Common concerns
”I don’t want random scripts running on my Mac”
Fair. You can read the script before running it:q to exit. When you’re comfortable, run the install command.
”Terminal asked for Xcode Command Line Tools”
This is Apple’s tooling that Homebrew needs. Click Install in the pop-up dialog and wait a few minutes. The install resumes automatically.”Can I close Terminal afterward?”
Yes — after setup completes. To keep FideliOS running automatically after closing Terminal, also run:http://127.0.0.1:3100 as long as your Mac is on.
