To stream a radio station to YouTube Live from a Mac mini, send the station’s audio and a suitable visual through an encoder such as OBS, then connect that encoder to an eligible YouTube channel. The exact steps depend on your macOS version, audio source, Mac mini generation and network, so verify the details on your own equipment before relying on a long broadcast.
Treat the job as six separate checks: channel access, source audio, encoder scene, YouTube destination, rights and ongoing monitoring. A radio signal reaching listeners over the air does not by itself establish permission to transmit the same music on YouTube.
Check that the channel can go live
Before installing or configuring anything, sign in to the YouTube account that will host the stream and check its live-streaming eligibility in YouTube Studio. YouTube’s live streaming requirements say a channel must be verified and must not have live-streaming restrictions in the preceding 90 days. First-time activation can take up to 24 hours, according to YouTube, so do not leave this check until the hour you plan to launch.
If you manage a station on behalf of a business, confirm that the account you use has the right channel permissions. The person who can upload a video may not necessarily be the person who can configure or start a live broadcast. If access changed recently, this guide to checking a YouTube stream key after channel permission changes may help separate an account issue from an encoder issue.
Decide whether this is a one-off programme or a continuous radio simulcast. For a scheduled programme, you can prepare the live event in advance and check the preview before selecting Go live. For an always-on station, plan how a human will notice a failure, what should happen after a power or network interruption, and who can safely restart the broadcast. An encoder configuration is not a substitute for an operational plan.
Identify the Mac mini and macOS setup
Write down the Mac mini’s model or generation, installed macOS version, available storage and the network connection you intend to use. This is not paperwork for its own sake: software options and audio-device behaviour can vary with the system and peripherals. Do not assume that advice for a different Mac mini, macOS release or connection applies unchanged.
Check the current OBS Studio download and system requirements for your exact macOS version before installing it. OBS is an encoder that can combine audio and visual sources and send a live feed to YouTube. If the current OBS release does not support your system, do not install an unofficial build or expect another version to behave the same way; check the project’s official guidance and choose a supported workflow.
Consider the Mac mini’s role in the station. If it will run the radio player and OBS on the same computer, confirm that the player can remain open and that OBS can receive its audio on that version of macOS. If sound comes from a mixer or another device, confirm that the Mac can see and select that input. A device appearing in system settings does not prove that the signal is at the expected level or that OBS is receiving it.
Keep the system focused during a test. Close applications you do not need, prevent avoidable sleep interruptions using the controls available in your macOS version, and check that updates or restart prompts will not interrupt the planned session. These are precautions, not guarantees of uninterrupted operation. For a static radio visual, begin with a modest scene and test what the Mac and connection can sustain rather than choosing a demanding animated layout by default.
Choose the radio audio source
First locate the signal you actually want YouTube to hear. It may be an internet radio feed playing in an application, a mixer’s output, or an audio device carrying the station programme. The encoder must capture that source, not merely show a moving meter from a microphone or another application.
If the station feed plays in a Mac application, check whether your chosen capture method can receive that application’s output on your macOS version. OBS’s audio sources guide describes audio input and output capture sources, but available behaviour and permissions depend on the operating system. Test the real player, not a substitute tone. If macOS asks for audio-capture permission, review the system prompt and privacy settings rather than bypassing them.
If the source is an external mixer, identify its actual output connector and signal type before buying an interface or cable. The Mac mini’s available inputs, the mixer’s outputs and the interface’s inputs must match; the article title does not specify those details. OBS can select an audio device as a source, but it cannot fix an incompatible connector or a badly set mixer output. A USB audio interface may be useful when the equipment requires one, but it is not automatically needed when the audio already plays in software.
Compare the paths before settling on one:
| Audio path | What OBS needs to capture | Main check before broadcast |
|---|---|---|
| Radio feed in a Mac application | That application’s audio, if supported by the system and capture method | Confirm the right application is selected and no duplicate output is added |
| External mixer or audio device | The selected input device or interface | Match the mixer output to the interface input and check levels |
| Separate radio receiver or player | A physical audio output connected to a suitable input | Verify cabling, channel selection and the signal arriving at the Mac |
The comparison is about routing, not sound quality. Whichever path you use, listen at the encoder’s output and watch its audio meters while the station is playing. If the meters are silent, investigate source selection and permissions. If they react twice to the same programme, look for duplicate capture paths or feedback between devices. Make a short local test recording if available so you can review levels and listening quality without relying on a live audience to report a problem.
For a recurring station, keep the signal path easy to explain: source, any mixer or interface, capture source in the encoder, then YouTube. Label the device and cable if several look alike. If the station changes from software playback to a physical mixer, retest the entire chain rather than assuming that the old scene remains valid.
Build an encoder scene with a visual
A radio stream still needs a video signal for YouTube Live. In OBS, create a scene and add the station artwork, a programme image or another visual you have permission to use. A static image can be enough for a straightforward simulcast; animated graphics are optional and add another element to test. Make the station name and any schedule information legible at the size viewers will see, and avoid artwork that suggests a programme is live when it is not.
Add the audio source identified in the previous section. Speak or play a representative part of the station feed, then check that the audio meters respond and the preview displays the intended visual. Listen through headphones connected to the Mac or another monitoring route that does not feed its own audio back into the stream. Watch for clipping, silence, unexpected notifications or another application’s sound.
Set video and audio parameters based on the scene and what the equipment and connection can reliably send. YouTube’s encoder settings guidance lists supported formats and recommendations; settings are not a promise that a particular Mac mini or internet connection can sustain them. For stereo audio, YouTube recommends 44.1 kHz and 128 Kbps. Its guidance also recommends a two-second keyframe interval and says not to exceed four seconds. Check the current official page before using these values, as platform recommendations can change.
A static radio image does not need a high frame rate simply because the encoder offers one. Choose a resolution and bitrate that suit the visual detail, the Mac’s observed behaviour and available upload capacity. YouTube’s H.264 table lists 1080p30 at 5 Mbps minimum and 14 Mbps recommended, and 720p30 at 3 Mbps minimum and 8 Mbps recommended. Those are YouTube recommendations, not a guarantee that your Mac or connection can maintain the stream. A simpler 720p scene may be more sensible than a higher setting if your upload or encoding test is marginal.
Save a copy of the scene configuration and note the source names and settings you tested. Do not put account credentials, a stream key or private contact details into an image source that could appear on air. If you are preparing a loop of recorded programming rather than a live radio feed, this guide to looping a long meditation video in OBS addresses a different source workflow; a radio application or mixer still needs its own audio routing.
Connect to the YouTube broadcast
In YouTube Studio, create or open the live broadcast in Live Control Room. YouTube provides a stream URL and stream key for the encoder; enter these in OBS’s streaming settings, using the server URL provided by YouTube. YouTube recommends RTMPS, its encrypted form of RTMP, when the encoder offers that option. Use the current address shown in Live Control Room rather than copying a value from an old setup or another channel.
Treat the stream key like a password. It authorises an encoder to send video to your channel, so do not put it in a public scene, screenshot, shared document or chat. If you believe it has been exposed, use YouTube’s reset process and update the encoder with the replacement. Keep any written setup note somewhere private and restrict access to people who actually need to operate the broadcast.
Start the encoder and wait for YouTube’s preview to receive the picture and sound. For a scheduled stream, confirm the preview and event details in Live Control Room before selecting Go live. Do not assume that pressing Start Streaming in OBS alone makes the broadcast public; the steps depend on the event setup. Check the title, visibility, schedule and audience settings while you are there.
If OBS does not connect, separate the checks: confirm the right channel and stream key, inspect the server URL, check whether YouTube is receiving a preview, and then examine the Mac’s network path. If the stream key appears correct but YouTube rejects it, this troubleshooting guide for a key that stops working after permission changes covers one possible cause. For a connection problem specific to an Indian ISP, use the relevant Airtel broadband RTMP checks rather than changing multiple encoder settings at random.
Clear music rights and test the stream
A station’s existing terrestrial or online permissions do not automatically settle whether the same repertoire may be simulcast on YouTube. Rights depend on territory, repertoire, contracts and the intended online use. Before streaming, check with the relevant rights holders or a qualified adviser that the permissions cover this specific transmission and any archive or replay you intend to leave available. YouTube’s live stream settings guidance also tells creators to respect audio and video rights and follow Community Guidelines. This is a prompt to check the rules, not a determination that a particular station is cleared.
Include every element in the review: music, jingles, recorded advertisements, presenter voice, artwork and any clips inserted into the programme. A station may have rights for one distribution route but not another. Keep a record of the permissions you relied on and the territories or formats they cover, and ask the rights holder if the scope is unclear. Do not treat the fact that a track is already broadcast elsewhere, or that a stream is non-commercial, as proof of permission for YouTube.
Test the complete route before the intended launch: play representative station content, capture it in OBS, inspect YouTube’s preview, and monitor what a viewer would hear and see. YouTube recommends testing with representative audio and movement, checking the preview and stream health, and monitoring the broadcast. A brief test can reveal a silent source, an incorrect image, a level that is too low, doubled audio or a visible desktop notification.
Check upload capacity rather than relying on a download speed result. YouTube recommends leaving 20% bandwidth headroom for the stream. A speed test is only a snapshot; if other people or devices share the connection, their use can affect what is available. Test at a time and with a scene similar to the planned broadcast, and avoid setting the encoder at the edge of the measured upload capacity.
For the first real session, have someone watch the YouTube playback from a separate device and report what arrives, not just what OBS shows locally. Check that the audio stays in sync with the visual, that the intended station feed is audible, and that the picture is stable. If the stream is meant to be continuous, run an extended private or otherwise appropriately limited test where possible, while recognising that one successful test cannot establish how every future overnight session will behave.
Monitor operation and understand archive limits
Once live, monitor both the encoder and YouTube’s stream health. A green-looking preview at launch is useful but does not tell you what will happen after an ISP interruption, macOS update, audio-device disconnection or power loss. Decide who will check the stream, how often, and how they will reach the Mac or YouTube account if something needs attention. A low-power machine or managed cloud workflow may suit some operators better, but the right choice depends on whether you need to preserve a live input, a local mixer, or just transmit a prepared file.
Keep the Mac and audio source in the state you tested. Avoid unplugging an interface, changing the default audio device or routing system sound while the encoder is running. If a failure occurs, note the time and what changed before restarting; a repeatable diagnosis is more useful than making several setting changes at once. Have a fallback plan, such as who can end the event and what listeners should see if the station feed itself stops.
YouTube may archive a live stream after it ends, but archive behaviour and availability depend on stream and account circumstances. Check YouTube’s current stream settings and archive help and decide what you want to retain before going live. Do not assume an archive will be complete, remain available indefinitely or be suitable as a replacement for your own recording. If you need a master copy, arrange a separate recording workflow and confirm that your rights permit retaining and publishing it.
If the actual need is to keep a prerecorded file broadcasting around the clock, rather than keep a Mac mini, radio player and live signal path running, a hosted file-to-live workflow may remove the task of leaving your computer switched on. StreamNeo turns an uploaded video into a YouTube live stream, which addresses that specific computer-left-running burden; it is not a replacement for capturing a live radio signal or resolving music rights. For a wider comparison of approaches, see options for running an always-on YouTube channel.
A final checklist should fit on one page: channel access verified, source and scene tested, rights checked, stream details stored privately, upload tested, monitoring responsibility assigned, and archive expectations decided. Revisit the official YouTube and OBS documentation before a major change to macOS, source hardware or channel setup. The workflow is dependable only to the extent that its particular parts, permissions and people are ready.

FAQ
Can I stream a radio station to YouTube Live from a Mac mini?
Yes, if the channel is eligible, the Mac and its software can capture the intended audio, and the encoder sends a video-and-audio feed to YouTube. The exact capture method depends on your macOS version and whether the station source is an application, mixer or separate device. Test your own setup before relying on it.
Do I need an audio interface?
Not necessarily. If the radio feed already plays in an application and your chosen capture method can receive it, you may not need extra hardware. A mixer or other physical output may require an interface whose inputs match that equipment; check the connectors and signal path before buying anything.
Does a radio station’s existing licence cover YouTube?
Not automatically. Permission depends on the relevant rights, territory, repertoire and online use, so confirm the scope with the rights holders or a qualified adviser before broadcasting. YouTube’s guidance is not a ruling on your station’s particular permissions.
Will YouTube keep an archive of the stream?
Do not rely on an archive without checking the current YouTube guidance and your event settings. If you need a durable master recording, plan a separate recording and confirm that retaining or publishing it is within your rights.
