Here's how to activate it, move it and find your key again. Updated 2026-11-03 ## Short answer - **Activate:** open the app, paste your license key and choose **Activate**. You need an internet connection for this. - **Two installations:** each license covers two active installations at once. Free one with **Deactivate This Installation** in the app, or from your account. - **Your key:** sign in to [your account](https://polar.sh/nina-labs-ai-llc/portal) with the email address you used at checkout to see your key, downloads and installations. ## What you get Buying on this website gets you a license for Open Sound Connect, a one-time purchase rather than a subscription. The license: - covers **up to two active installations** at the same time, for example your MacBook and a desktop Mac; - is activated in the app with your **license key**; - comes with the app download, both available in your account after checkout. The [Mac App Store](https://opensoundconnect.app/download) version, coming soon, is separate: Apple handles the purchase and updates, and it doesn't use a license key or count installations. ## Activate your installation 1. Download the app from your account, move it to Applications and open it. 2. Open your purchase in your account and copy the key from **Open Sound Connect License**. 3. Paste it into the app's **License key** field and choose **Activate**. The app shows your installation as **Mac** followed by a short random code, so you can tell your installations apart. It never uses your Mac's name or serial number. ## Two installations, and moving to a new Mac An installation is one copy of the app for one macOS user account on one Mac. Opening the same copy again, or replacing it with a newer version, keeps its activation. To move to another Mac when both installations are in use: 1. On the Mac you're leaving, open **Settings → License** (or **Open Sound Connect → Manage License…**) and choose **Deactivate This Installation**. 2. On the new Mac, activate with the same key. No access to the old Mac? Sign in to your account and deactivate that installation there. Deleting the app alone doesn't free its slot: the activation stays counted until you deactivate it. ## Offline use and checks Activation needs an internet connection. After that, the app checks the license when it opens, when you return to it and every 15 minutes while it runs. If your Mac is offline, the app keeps working for **up to seven days** after its last successful check, then asks to reconnect. If a license is deactivated from your account, the copy that used it stops controlling headphones at its next check and asks for a key again. ## What the check sends The license check sends your license key, the activation's ID and the random installation ID to our licensing provider. It sends nothing about your headphones, your settings or what you listen to. The [privacy policy](https://opensoundconnect.app/privacy) has the details, and your key is stored in your Mac's local Keychain. ## Get help with a purchase Most purchase questions (finding your key, downloading the app again, seeing your installations) are answered in [your account](https://polar.sh/nina-labs-ai-llc/portal): sign in with the email address you used at checkout. For anything else, the [support page](https://opensoundconnect.app/support) has the ways to reach us. ## Common questions ### I lost my license key. Where do I find it? Sign in to [your account](https://polar.sh/nina-labs-ai-llc/portal) with the email address you used at checkout. Your key is in your purchase, under **Open Sound Connect License**. ### Can I use one license on two Macs? Yes. Each license allows two active installations at the same time. To use a third Mac, deactivate one of the other two first. ### Does reinstalling the app use up an activation? No, as long as it's the same Mac and macOS user account: the activation is kept in your Keychain and the app reuses it. Deactivate first if you're giving the Mac away. ### Do I need a license for the Mac App Store version? No. The Mac App Store version is bought and installed through Apple, under Apple's terms, and doesn't use a license key. ## Where to next - [Get Open Sound Connect for Mac](https://opensoundconnect.app/download): Get Open Sound Connect for macOS 15 or later, Apple silicon or Intel: a $9.99 license for two Macs, the download, install steps and requirements. - [Support and Getting Started](https://opensoundconnect.app/support): Get started with Open Sound Connect, fix Bluetooth and connection problems, learn the keyboard shortcuts and find answers about your Sony headphones. - [Privacy policy](https://opensoundconnect.app/privacy): What Open Sound Connect stores locally, how website purchases and license activations are handled, and how the App Store version differs. --- Open Sound Connect is independent software.
