A Mac mini can send a radio-style programme to YouTube Live using an encoder such as OBS Studio, with a still image or simple visual alongside the audio. The right settings depend on the Mac model, macOS version, audio source and internet connection, so test the actual setup rather than assuming the computer will handle every scene or bitrate.
Before building the broadcast, check that the channel can go live, decide how YouTube will receive audio, and confirm that your music rights cover both the live stream and any replay. Plan separately for monitoring and recording: an always-on broadcast still needs someone or something to notice when sound, picture or connection stops behaving as intended.
Decide what your radio stream will show
A YouTube radio stream is an audio programme delivered as a live video feed. The picture might be a station logo, a track title card, a devotional image, a modest waveform visualiser or a scene that changes between segments. The simplest scene is often the easiest to keep legible and troubleshoot during a long broadcast.
Choose the visual according to the programme, not to fill the screen with motion. If listeners mainly want bhajans, a clear station identity and current programme label may be more useful than a complex animated background. For a local news or community station, a title card can explain what is playing and when the next update is due. Check that the text remains readable on a phone, where many viewers will find the stream.
Decide whether the broadcast is a finite scheduled programme or meant to run continuously. A scheduled show has a clear start and end and can be announced ahead of time. An always-on station has additional operational questions: how to handle interruptions, who checks the output, how to rotate sessions before YouTube's archive boundary, and whether a local recording is needed.
A still image paired with a playlist is not the same as a complete station workflow. You need an audio source that OBS can capture, a scene that reaches YouTube, and a way to confirm that both are still working. If your project is a loop of promotional video rather than audio-led radio, the hotel promotion loop guide covers a related always-on presentation problem.
Check the channel before setup day
YouTube requires a verified channel with no live-streaming restriction in the previous 90 days before you can stream. If live streaming has not been enabled before, activation can take up to 24 hours. Check access well ahead of the programme rather than discovering the delay at the intended start time. See YouTube's live-streaming enablement guidance for the current requirements.
Open YouTube Studio and look for the live-streaming controls. If the channel is managed by more than one person, confirm who has permission to create the event and who will hold the stream key. The key grants access to send a feed to the event, so treat it like a password: do not show it in a public screen recording, a shared troubleshooting screenshot or a scene that viewers can see.
Think through the account and event ownership too. A radio channel may be operated by a temple, shop, school or community group, while the person configuring OBS uses an individual account. Agree who can access Studio, who can end or schedule the broadcast, and where essential notes are kept. Do not put credentials in a public document just to make a handover easier.
If you want viewers to have a watch page in advance, schedule the stream in Studio and share that page through your usual channels. If the programme is a test, make its purpose clear and avoid assuming an unlisted setting is a substitute for checking every privacy and access choice. YouTube's event controls and interface can change, so follow the current instructions on its official help pages.
Choose and configure an encoder
OBS Studio is a practical software encoder for a Mac. The OBS Project download page lists macOS 13 and newer and provides separate installers for Intel and Apple Silicon Macs; select the installer that matches the computer. Confirm the Mac's processor and installed macOS before downloading, since “Mac mini” alone does not identify either. Check the OBS download page for current compatibility information.
OBS is free software published by the OBS Project. Its system-requirements guidance cautions that a compatible computer is not guaranteed to handle every combination of encoder, resolution, frame rate and scene complexity. A Mac mini model that works for a simple audio-and-image scene may not behave the same way with several animated sources, filters or higher-resolution video. Use OBS's Auto-Configuration Wizard as a starting point, then test your own programme and monitor the result.
Install OBS from the official source and follow its current Mac installation instructions. Once it opens, create a scene for the radio programme. Add the still image or other visual, then add the audio input or capture method that matches how the programme is produced. Watch the audio mixer meters while the source is playing. Movement in the meters is a useful first check, but it does not prove that the audience hears the right source or that YouTube is receiving it.
Audio routing varies. If playback comes from a browser or music application, you may need a method to route that application’s sound into OBS; if it comes from a connected mixer or other audio equipment, the input path will differ. The correct route depends on the exact Mac, software and source. Do not install a virtual audio driver based on a generic recipe until you know which signal you need to capture and have tested whether it is present in the OBS mixer.
In OBS, configure the stream connection using the event details from YouTube Studio. YouTube's encoder guidance recommends RTMPS, constant bitrate (CBR), a two-second keyframe interval, and supported codecs and audio settings. It lists H.264, H.265/HEVC and AV1 for RTMP or RTMPS video, and AAC or MP3 for RTMP(S) audio. The available choices in OBS can depend on the encoder and the Mac, so use settings compatible with the actual setup rather than treating every listed format as interchangeable.
Resolution and bitrate are a trade-off between picture detail and the sustained upload your connection can provide. A radio programme with a still image has little reason to chase a high video bitrate simply because the encoder offers it. Start with an appropriate modest video setting, follow YouTube's published ranges for the resolution and frame rate you choose, and test during the time of day and network conditions that matter to the station. YouTube recommends testing upload bitrate; a speed-test result is a snapshot, not a guarantee that a connection will sustain a broadcast overnight.
RTMPS is the ordinary choice for a straightforward radio stream. YouTube documents HLS as a specialised alternative for certain codecs or HDR workflows, with higher latency; it is not a reason to add complexity to a simple audio-led channel without a specific need. You can also compare this software setup with the OBS settings guide for a continuous devotional stream, while remembering that the other computer and scene may differ from yours.
Create the stream in YouTube Studio
In Studio's Live Control Room, create or schedule an encoder livestream. Give it a title, description and visibility that match the programme, then set any audience and event details that apply to your channel. Copy the stream URL and stream key into OBS's streaming settings. The URL is the destination for the encoder; the key identifies the stream. Keep both out of public view, especially the key.
A scheduled event is useful when you want to share a watch page ahead of time. For an unscheduled test, choose settings that prevent an unintended public broadcast. Confirm the event details before connecting the encoder: changing the wrong event or sending a programme to the wrong visibility can create confusion even when OBS itself is configured correctly.
Start the encoder output and wait for the Live Control Room preview to receive it. The preview is the checkpoint that tells you YouTube is seeing a feed; it is not enough to see that OBS says it is streaming. Check the picture, listen to the preview where available, and look for Studio's stream-health information before choosing to go live. YouTube's encoder setup instructions describe scheduling, entering connection details and waiting for the preview.
Once the event is live, open the public watch page on a separate device or browser session if possible. That helps catch a mismatch between the encoder preview and what viewers can actually access. It also gives you a practical check on volume, image layout and the event title without relying only on the operator's view inside OBS.
Test and monitor the broadcast
Run a rehearsal with the same audio source, scene, settings and network path you plan to use. Include normal programme material, not only a short silent test: music can reveal clipping, gaps, abrupt track changes or a source that stops when the computer locks or an application changes state. Check that the image is composed correctly and that the stream reaches YouTube's preview before announcing the event.
During the test, compare the OBS mixer with the Live Control Room preview and the public watch page. Confirm that the intended audio is audible, the picture is not blank or cropped, and the event can be opened on a phone or another device. Watch YouTube's stream-health messages and OBS output status. If the connection struggles, reduce the demand on it and repeat the test instead of assuming a single successful start proves overnight stability.
For an always-on channel, decide who will check the broadcast and what they will check. A useful routine includes listening for sound, looking at the picture, checking that the encoder remains connected, and confirming that the local recording—if you use one—is actually growing. YouTube's own live-streaming tips recommend testing with conditions similar to the planned stream and checking the preview and stream health.
A local recording can provide a copy if the live event has a problem, but it also uses storage and needs its own checks. Confirm the destination has space, the recording is being written, and the file can be played before relying on it. Recording a stream does not repair an interruption for viewers, and saving a copy does not guarantee YouTube will retain the live archive.
Plan for interruptions without claiming that any machine or connection will never drop. Keep the event details and recovery steps somewhere the operator can reach them, and know how to restart the encoder or reconnect the event if needed. If several people share responsibility, rehearse the handover so they know which Studio event is active and how to avoid exposing or replacing the stream key by mistake.
For home broadband in India, the upload path can vary by provider, time and network conditions. A wired connection may be useful if the Mac and router support it, but it is not a universal requirement or a guaranteed fix; check the specific equipment and compare performance in your setup. The home broadband guide for 24/7 YouTube streams explains the connection trade-offs without making a promise about an individual line.
Clear music rights for live and replay
Music permission is part of the station plan, not a check to leave until after launch. Confirm that you have the necessary rights for each track to be broadcast live on YouTube and, if you intend to keep the replay, to remain available in an archived video. Permission to play a song in a shop or on a personal device does not by itself establish permission to retransmit it online.
Read the terms attached to the source of each track. Check whether permission covers live streaming, replay or archive, territories, attribution, edits and continuous or repeated use. Keep the licence, receipt or written permission with the playlist notes so the operator can identify what applies to each item. If a track's conditions are unclear, leave it out until you have confirmed them with the rights holder or the licensing provider.
YouTube warns that a livestream can be terminated after a copyright strike, and that completed archived streams can receive Content ID claims. A claim or strike can affect the programme and its availability, so rights clearance does not become unnecessary merely because a stream is labelled “radio” or uses a static picture. Check the current YouTube copyright guidance for live streams and seek appropriate advice if the rights situation is uncertain.
YouTube Creator Music is not a blanket station licence. Its documentation describes availability for creators in the US YouTube Partner Program, with expansion to non-US YPP creators pending, and licensing is handled track by track. Even where a track is available to you, inspect its individual terms and verify that they cover your intended continuous live use and replay. Do not infer a permission from the presence of a track in a tool.
If you are producing devotional or guided audio as well as music, treat recordings, arrangements and underlying compositions as separate things to check. A performance you commissioned may involve rights held by the performer, composer, label or another party. The audio format guide for looping guided meditations can help with the production side, but file format does not establish music permission.
Plan around YouTube's archive limits
YouTube says streams shorter than 12 hours can be automatically archived, while streams that exceed 12 hours may not be captured at all. That makes a single uninterrupted all-day session a poor archival assumption. If keeping a replay matters, plan session lengths below the documented boundary and verify the current YouTube guidance before relying on an archive.
A 24/7 station therefore has two different jobs: keeping a live programme available and preserving recordings people can watch later. You can design scheduled sessions that hand off between broadcasts, but the breaks and event pages should be tested so they make sense to viewers. Alternatively, decide that live continuity matters more than a complete YouTube replay, and keep an independent local recording if you need a copy. Neither approach removes the need to check rights for the archived material.
If you record locally, make sure the recording path is independent enough to be useful when YouTube's archive is absent. Check storage space, file growth and playback, and decide who will manage or delete recordings when they are no longer needed. A recording that silently stopped or filled the disk is not a dependable backup, so include it in the monitoring routine rather than treating it as set-and-forget.
Document the session rotation and handover. Note which event is active, when the next one starts, who checks audio and picture, and where the local file is saved. Try the schedule and archive process with a non-critical test programme first. YouTube's archive behaviour and Studio controls can change, so consult its current guidance on live-stream archives before settling on a routine.
Put the workflow into operation
A sensible order is to verify the channel, install the correct OBS build, make one simple scene, establish the audio route, create a Studio event, and test the full path from source to watch page. Only after that should you decide whether to add a visualiser, multiple scenes or automation. Each extra element adds another place to check when a listener reports silence or a frozen image.
For the first planned broadcast, keep a human available to listen and watch. Capture notes about the chosen settings, the Mac and macOS details, the audio source, the connection, and what the Studio preview showed. That record turns troubleshooting into a comparison with a known working session rather than guesswork, without implying that the same result will hold after every software or network change.
If the specific pain is leaving your own computer running throughout the day and night, StreamNeo addresses that by turning an uploaded video into a YouTube live stream that can continue with your computer switched off. It is YouTube-only, so it suits a prepared file rather than an OBS radio workflow whose audio or visuals need to change live; decide which kind of programme you actually need before choosing how to operate it.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Can I run a YouTube radio stream from any Mac mini?
The name alone is not enough to say. OBS's requirements and performance depend on the processor, macOS, encoder choice, scene and other work the Mac is doing, so check the current OBS compatibility details and test your own setup before planning a long session.
Do I need a visualiser for a radio stream?
No. YouTube receives a video feed, but that can be a still image with a station name or programme information. A visualiser is an optional presentation choice, and it is worth adding only if it remains readable and behaves reliably in your tests.
Can I leave one stream running for a full day?
You may choose to run a continuous broadcast, but YouTube says a stream exceeding 12 hours may not be captured as an archive. Plan session rotation and a local recording if replay matters, then test the breaks and recording process rather than assuming the platform will preserve the full programme.
Will YouTube let me play any music if the stream is non-commercial?
Do not assume that. Confirm that the rights cover online live transmission and any replay, and check YouTube's current copyright guidance; a non-commercial purpose does not by itself establish permission.
