The questions people actually ask

Neither. The Mac at home registers with our meeting point over HTTPS and waits there; you just type its 9-digit ID on the other machine. No VPS to rent, no networking software to install, no ports to forward. If you already run your own VPN it keeps working — that sits a layer below and the app never needs to know.

Only when the two machines cannot see each other directly. On the same network the app connects straight across and not a byte leaves your building. Over distance the packets do pass through the meeting point — but it cannot read them: session keys come from the 6-digit code plus an ECDH secret the server holds no part of, so to it everything is random bytes.

Mac@Xa is commercial software and needs a licence. Pricing is being finalised and will be published with the release. Write to us if you would like to hear when it goes on sale.

Screen Sharing speaks VNC: it sends rectangles and waits a full network round trip per frame, which you feel immediately over distance. Mac@Xa compresses H.264 on the chip and streams continuously, so the same link carries a smooth picture. Screen Sharing also won't get you through the router at home — Mac@Xa handles that part too.

Yes — that is exactly why it was built this way. Sessions travel over port 443 and look like an ordinary HTTPS connection to any firewall, so there is nothing to request from IT and no VPN to stand up. Hotel Wi-Fi and mobile data behave the same way.

No. The Mac at home generates its own 6-digit code for remote control, which you can rotate at any time. It is completely separate from your macOS login password.

Around 8 Mbps for a sharp 1920-pixel-wide picture, and the app lowers the bit rate as the link degrades. For something lighter, stream a single app window instead of the whole desktop — plenty of work only needs that.

The iPhone and iPad app has been submitted to the App Store and is waiting on Apple's review — once it clears, you install it from the App Store like anything else. Until then, anyone comfortable with Xcode can build it from source; the Guide walks through it step by step.

Take your money back within 30 days, no reason needed — one line to info@macxa.app with your order number is enough. Where the law grants a 14-day right to cancel digital goods, that right stands untouched; our 30-day promise is wider, not a replacement.

No, and that is deliberate. The Mac at home serves exactly one visitor at a time, so you always know who your screen is open to.
