NeuroSync — setup guide

NeuroSync is the native macOS instrument for your NeuroFocus around-ear EEG. It’s a real CoreBluetooth client: it connects to the headset, decodes the raw sample stream, and computes your focus on-device — the Pope β/(α+θ) engagement index, scored 0–100 against your own baseline. Focus, calm, and jaw-clench, live on your desktop.

01You need

• A Mac with Apple silicon running macOS 26.1 or later.
• For live signal: a NeuroFocus around-ear EEG headset, charged and nearby. (Focus Block works without one.)

02Install

• Download neurosync.dmg (above), open it, and drag NeuroSync to Applications.
• It’s signed with an Apple Developer ID and notarized by Apple, so it opens straight from Applications — no Gatekeeper “unidentified developer” override needed.
• On first launch, macOS asks for Bluetooth permission (to reach the headset) — allow it.

03Connect the headset

• Power on the headset and click Connect. NeuroSync pairs over Bluetooth and starts decoding the stream.
• Wear it for the 20-second calibration — the app measures your own baseline, then scores you against it. Until calibration finishes there is no number to show, and the app says so.

04Read your focus

• Focus, calm, and clench update live while you work; the menu bar carries the current focus.
• No headset yet? Start a Focus Block — a timer for a deep-work push — and review it in the DAY view afterward.
• When a session ends, it’s saved to your Mac. The DAY view rolls up your segments so you can see when you were actually in flow.

05Privacy

Local-first: your neural data is written to a folder on your Mac and never leaves it unless you turn on cloud sync, which is off by default. Beyond the EEG stream over Bluetooth, the app reads only your frontmost app’s identifier and read-only calendar titles — used on-device to label a session’s context, never uploaded on their own.
