Quick answers
What macOS version do I need?
macOS 14 (Sonoma) or later.
Does PurpleWave collect my data?
No. All credentials stay in your macOS Keychain. No analytics or tracking in the app.
Can I cast to multiple devices at once?
You can cast to one device at a time, but you can switch between devices instantly.
What devices are supported?
Chromecast, Google TV, Nest Hub, Nest speakers, and any Cast-compatible device.
Is there an audio-only mode?
Yes. Enable it in Settings to skip video and save bandwidth.
My device is not showing up.
Make sure both your Mac and Cast device are on the same network. Check System Settings > Privacy & Security > Local Network.
Why do I see ads with YouTube Premium?
Some Cast devices (like older Chromecasts) don't have their own Google login. PurpleWave can't pass your Premium credentials to these devices — this is a Google limitation, not a bug. Devices with their own login (Nest Hub, Chromecast with Google TV) will play ad-free.
