If by a “24/7 YouTube playlist stream” you mean leaving a Mac mini to play YouTube continuously on a screen, the current base Mac mini with M6 is a proportionate starting point. That recommendation follows Apple’s published specifications, not a hands-on uptime test, and it does not establish that the Mac is suitable for broadcasting a continuous live programme to viewers.
The distinction matters: playing a playlist in a browser is not the same workflow as sending a live video signal to YouTube. Before buying hardware, decide which of those jobs you mean, because the second has requirements this Mac mini specification check cannot resolve.
Playback or live broadcasting?
A playlist can mean a queue of YouTube videos watched on a Mac, a local folder of video files played on a display, or a prerecorded programme continuously broadcast as a YouTube Live event. These sound similar in casual conversation, but they ask different things of a computer. In the first two cases, the Mac is a playback device. In the third, it is part of a live production and transmission workflow.
For ordinary playback, the Mac decodes and displays video. The video may come from YouTube over the network or from storage, and the system needs to keep the player and display active. That says little about whether a computer can encode a programme, maintain a live connection to YouTube, recover from a dropped connection, or continue in a particular streaming application without attention.
If you are planning a devotional playlist for a temple screen, a lofi queue in a shop, or a study playlist on a dedicated display, this article’s hardware recommendation applies as a starting point for playback. If viewers need to see a continuous live broadcast on your channel, treat that as a separate architecture decision. The guide to running a 24/7 YouTube Live stream from an Ubuntu VPS is relevant to that different question, but its existence does not by itself establish that a VPS or a Mac is right for your channel.
The current base Mac mini
Apple’s 2026 technical specifications identify Mac mini configurations with M6 and M5 Pro. The base M6 configuration is listed with 16 GB unified memory and a 256 GB SSD. Apple also lists an HDMI connection, Ethernet, Wi-Fi 7 and a hardware video decode engine. The Mac mini technical specifications and Apple’s M6 and M5 Pro specification page are the primary references to check before buying, since the exact configuration offered in a shop may differ from the base configuration described here.
The M5 Pro starts with more memory and storage in the material reviewed: 24 GB unified memory and a 512 GB SSD. It also has Thunderbolt 5, while M6 has Thunderbolt 4. Apple documents other distinctions, including display support and chip or media capabilities. Those are meaningful if your work needs them, but the published comparisons cited here do not show that they make M5 Pro necessary for straightforward playlist playback.
That is why the base M6 is the proportionate starting point, rather than the more capable M5 Pro. The recommendation is not that every buyer must choose M6, or that it is the cheapest suitable device in every market. No current prices were researched, so compare the purchase cost and the exact configuration available to you rather than treating a model name as a complete specification.
What the published specifications suggest for playback
A hardware video decode engine is the most directly relevant item in Apple’s specification for video playback. It indicates that the system includes dedicated media capability for decoding supported video formats. It is reasonable to infer that basic playlist playback is a light-use task for a current Mac mini with this capability. That is an inference from published hardware, not a measured playback result or a guarantee about a particular file, browser, display or service.
The base 16 GB of unified memory and 256 GB SSD also provide a reasonable starting configuration if you are primarily playing video rather than editing it, keeping large media libraries on the Mac, or running several production applications at once. If your playlist is hosted on YouTube, local SSD capacity may not be the limiting factor because the video is delivered over the network. For locally stored videos, check the total size of the files and leave room for other software and system data. Neither memory nor storage capacity, by itself, says how reliably a machine will operate over a long period.
The built-in HDMI output can connect the Mac to a compatible display, and Ethernet gives you a wired network option. A wired connection is a sensible choice where the Mac and router can be connected conveniently, particularly for a fixed installation, but the research behind this article does not establish that Ethernet is required. Wi-Fi is also listed. Network stability depends on your connection and setup, not just the port or wireless standard printed on the computer’s specification page.
For a single display showing a video queue, the M5 Pro’s higher starting memory and storage do not have a demonstrated playback advantage in the evidence reviewed. You may have a reason to buy it if you also edit videos, drive a more demanding display arrangement, or run other workloads that use its additional capabilities. But buying the higher tier just because “24/7” sounds demanding would confuse elapsed time with workload: a simple task running for longer is not automatically the same as a more intensive task.
Use power and operating conditions carefully
Apple publishes power-consumption figures for specified 2024 Mac mini systems, not for the M6 and not for continuous YouTube playback. Its support table gives 4 W idle and 65 W maximum for a 2024 M4 Mac mini with 16 GB memory and a 256 GB SSD, and 5 W idle and 140 W maximum for a 2024 M4 Pro system with 64 GB memory and an 8 TB SSD. Apple says the figures are measured at the wall and include power-supply and system losses; its “CPU Max” condition describes a compute-intensive application maximising processor usage. See Apple’s Mac mini power consumption and thermal output information for the context.
Those figures are not an estimate of what an M6 will draw while playing a playlist. They should not be multiplied into a promised annual electricity bill: actual playback draw, other connected equipment, how the Mac is used, and your local electricity tariff are not established by these published measurements. If energy cost matters, use a suitable meter on the actual setup and your own tariff, while keeping in mind that a short measurement may not represent every condition.
Apple lists an operating-temperature range of 10°–35° C and idle sound pressure of 5 dBA at the operator position for the current Mac mini specifications. Those are manufacturer specifications, not an endurance claim. Put the computer somewhere with the ventilation and ambient conditions the manufacturer describes, avoid placing it where heat can build up, and check the setup after installation rather than assuming the room remains within a particular range year-round.
ENERGY STAR’s record for a specific M4 Mac mini configuration lists standardised power states including long idle, short idle, sleep and off. These are not active-video playback readings, and they are not a certification claim about M6. Standards-based figures can help compare like with like, but they do not answer how much a real machine consumes while playing your particular playlist.
What these specs do not establish
Specifications describe components and stated operating conditions. They do not tell you that a Mac mini will stay awake indefinitely, that a video service will keep playing without interruption, or that a particular Mac will last a certain length of time. This recommendation is based on published specifications; no hands-on 24/7 workflow test was performed or found for this article.
Nor do the listed decode engine, memory, storage and connections establish a live broadcast workflow. A continuous broadcast adds questions about the application or encoder, the format and settings of the video, how the channel is configured, the available upload connection, what happens when the network drops, and who receives an alert or restores the programme. The evidence reviewed for this article does not settle those requirements or prove that a local Mac is the right design.
Treat “24/7” as an operating intention, not a hardware property. A machine can be left on, but the overall result also depends on power, network, playback software, display settings, updates and human recovery plans. If playback stopping would leave a public display blank overnight, for example, you need a way to notice and respond. That operational need is separate from choosing a chip.
Does your workflow need an encoder?
If the Mac only plays an existing YouTube playlist for a local audience, it is not encoding a new live programme for YouTube. In that narrow case, a video decode capability is relevant and the base M6 is a sensible point to start from. Keep the playback task simple, test the exact playlist and display combination you plan to use, and check how the player behaves after a pause, network interruption or restart.
If the aim is to send prerecorded video as a continuous live event, you need a workflow that produces and transmits a live signal. Software such as OBS can be part of that workflow, but its presence does not settle the settings or whether a Mac mini can meet your requirements. You would need to verify the current YouTube guidance and the instructions for the software you choose. The OBS profile and scene collection setup guide can help with saved configuration, while the YouTube bitrate settings checklist is useful only once you have established that OBS broadcasting is the workflow you intend to use.
Encoding and playback place different demands on a machine. A device that comfortably decodes a video for display is not automatically established as adequate for producing and transmitting a live programme at a chosen resolution and frame rate. Conversely, choosing a higher-tier processor without checking the full workflow does not solve poor upload capacity, an unsupported setup, or the need to recover from a failure.
For the same reason, do not choose a Mac mini model based on an assumption that M5 Pro is “safer” for a live broadcast. The cited material does not include a tested continuous broadcast, a supported YouTube configuration for this exact use, or comparative results. Confirm the relevant software’s current requirements and YouTube’s current live-streaming guidance before purchasing around a broadcast plan.
Choose the workflow before the model
A simple decision table can keep the purchase proportionate. It does not replace testing the exact setup, but it separates what the published hardware specifications can support as an inference from what they cannot answer.
| What you want to do | Starting point to consider | What to verify next |
|---|---|---|
| Play a YouTube playlist on one local display | Base Mac mini with M6 | Display connection, network access, player behaviour and restart procedure |
| Play files stored on the Mac | Base Mac mini with M6, if the library fits the storage plan | File sizes and formats, free storage, display and playback app |
| Edit video as well as play a playlist | Compare M6 and M5 Pro against the editing application and workload | Software requirements, storage needs and display setup |
| Broadcast prerecorded video continuously to YouTube Live | Do not choose a model from this playback comparison alone | Encoder, YouTube workflow, upload connection, recovery and monitoring |
If your use is local playback, the purchase decision can stay modest: start with the base M6, choose enough storage for any local library, connect the display, and prefer Ethernet when a stable wired connection is practical. If you need more storage, account for that explicitly rather than treating extra processor capability as a substitute for disk space.
If your use is live broadcasting, pause the hardware decision until you have mapped how the video is prepared, encoded, sent, monitored and restarted. A Mac may be part of a local workflow, but whether it is the right choice depends on the whole plan. The FFmpeg guide to preparing video for a YouTube loop stream covers another part of that problem: preparing media is not the same as keeping a live broadcast running.
For readers who do not want a personal computer kept on merely to maintain a prerecorded broadcast, StreamNeo can remove that specific computer-at-home burden: you upload a video, provide your YouTube stream key, and the cloud-run broadcast continues with your computer switched off, with monitoring and automatic restart if it drops. It is YouTube-only, and it does not remove the need to check your channel, content and live-stream workflow requirements.

FAQ
Is the base M6 Mac mini enough for a 24/7 YouTube playlist?
For ordinary playlist playback on a computer, it is a proportionate starting point based on Apple’s published decode capability and base configuration. This is an inference, not a hands-on 24/7 test or a promise of uninterrupted playback. Test the exact player, files, display and network you plan to use.
Should I buy the M5 Pro instead?
Not for simple playback on the evidence reviewed here: its higher starting memory and storage do not demonstrate a necessary advantage for that task. It may suit you if you also need its additional capabilities for production or other workloads. Compare the exact configuration and price available to you, because no current prices were researched for this article.
Does this recommendation mean the Mac mini is proven for YouTube Live broadcasting?
No. Playback and broadcasting are distinct jobs, and the cited specifications do not establish a continuous live-stream setup, encoder requirements or uninterrupted operation. Check current YouTube and software documentation against your intended workflow before buying hardware for a broadcast.
Do I need Ethernet?
Apple lists both Ethernet and Wi-Fi 7 on the current Mac mini. Wired Ethernet is a reasonable choice for a fixed setup when available, but the research here does not establish that it is required. Your actual network conditions and the consequences of a connection interruption matter more than the connector alone.
