For one ordinary YouTube playlist, the available specifications do not show that you need an M4 Mac mini: Apple lists video decode capability and support for common video formats on both the standard M2 and M4 models. The M4 adds AV1 decoding, but that is a format capability, not evidence that a playlist will play more continuously.
If you are choosing a Mac mini mainly for unattended playback, compare the complete configurations, actual purchase prices and other work you expect the computer to do. Neither chip specification nor a power-table figure can promise that a browser, network connection and YouTube session will keep running without interruption.
Is the M2 enough for one playlist?
For the hardware part of a single playlist playback workload, the standard M2 Mac mini has the documented ingredients for common video formats. Apple's technical specification lists a video decode engine alongside hardware-accelerated H.264, HEVC and ProRes support. The M4 lists those capabilities too, with AV1 decoding additionally named. These are format and media-engine facts, not a claim that either machine has been tested for days-long YouTube playback.
That distinction matters because “can decode the video” and “will keep a playlist playing unattended” are different questions. A video can be within the computer's decoding capabilities while playback still stops because the browser session changes state, the connection drops, an autoplay condition is not met, or the computer sleeps. The sources cited here do not establish the details of current YouTube autoplay behaviour or macOS settings for unattended playback, so this article does not prescribe a guaranteed configuration.
For a buyer whose only intended task is one playlist, there is no sourced basis here for paying more solely because the M4 is newer. The sensible conclusion is narrower: M2 has documented common-format support, and the cited specifications do not establish an M4 continuity advantage. If you also plan to edit video, run demanding applications, or keep the Mac for broader work, those other needs may change the purchase decision.
A Mac mini is also not the only way to run a 24/7 YouTube channel. If you need a computer to encode or play a playlist locally, macOS operation, power, networking and restart recovery are part of your own setup. If instead your source is a prepared video file and you do not want a computer at home left on, StreamNeo removes that specific burden by letting you upload the file and run the YouTube broadcast with your computer switched off; it is YouTube-only, and it does not make YouTube playback or channel compliance questions disappear.
What Apple documents for M2 and M4
Apple's model pages are useful for checking capabilities, but read them as technical specifications rather than as a head-to-head streaming test. The standard configurations share several relevant entries. Both list a video decode engine, hardware-accelerated H.264, HEVC and ProRes support, Wi-Fi 6E and Gigabit Ethernet. M4's page also lists AV1 decoding. The processor-core counts differ, but they cannot be converted into a claim about uninterrupted playlist operation.
| Documented item | Mac mini (2023), standard M2 | Mac mini (2024), standard M4 | What it means for this decision |
|---|---|---|---|
| CPU and GPU | 8-core CPU, 10-core GPU | 10-core CPU, 10-core GPU | A specification difference, not a YouTube playback benchmark |
| Video decode and formats | Video decode engine; hardware-accelerated H.264, HEVC and ProRes | Video decode engine; hardware-accelerated H.264, HEVC and ProRes; AV1 decode | Both list common formats; M4 adds AV1 in Apple's description |
| Network options | Wi-Fi 6E and Gigabit Ethernet | Wi-Fi 6E and Gigabit Ethernet | A wired option exists on both; local network conditions still matter |
| Continuous power rating | 150W maximum continuous power rating | 155W maximum continuous power rating | Product electrical ratings, not typical playlist consumption |
The descriptions above refer to Apple's standard M2 and M4 Mac mini specification pages, not every possible configuration or later product revision. You can consult Apple's Mac mini (2023) technical specifications and Mac mini (2024) technical specifications when checking a listing or comparing ports and requirements. Confirm that the product you are considering is the model described on the relevant page.
A shared line in a specification does not settle the whole workload. For example, both models offer Gigabit Ethernet, but that does not tell you whether the router, broadband connection, cable or YouTube session in your location will remain stable. Likewise, a listed decode format does not tell you which format YouTube will deliver in your specific browser session. The model page tells you what Apple documents for the computer; it does not predict the path from your playlist to viewers.
If your playlist is a sequence of music or worship videos, the file and sequence can also matter more than a processor-generation label. For playlist construction issues, the practical checks in troubleshooting playlist gaps in an FFmpeg stream address a different failure point from choosing a Mac's media engine. That distinction is useful: a machine upgrade cannot repair a gap that is already present in the source sequence.
What decode specifications do and do not tell you
A decode engine is hardware support for processing video formats. Hardware-accelerated format support can be relevant when an application is decoding compatible media, but it is not a complete description of what happens in every browser, player or streaming workflow. Apple's specification does not say that YouTube will choose AV1 for your playlist, that a browser will use a particular decode path, or that the computer will avoid pauses.
The M4's AV1 entry is therefore a genuine difference, but keep its significance bounded. It may matter if your other work involves compatible AV1 material and the applications you use take advantage of the documented capability. It does not, on its own, establish a visible improvement for a particular YouTube playlist. The research available for this comparison did not include a controlled test of the two computers playing the same playlist, with matched software, network and settings. There is no responsible way to turn the format entry into a continuity promise.
The same caution applies to CPU and GPU core counts. The standard M2 is listed with an 8-core CPU and 10-core GPU, while the standard M4 is listed with a 10-core CPU and 10-core GPU. That describes the listed chips. It does not show the CPU load for a chosen browser, the number of video elements in an elaborate setup, or whether a given stream encoder can keep up with a particular source. A playlist playing in a browser is not automatically equivalent to capturing, encoding and sending a live signal from production software.
It helps to name the job precisely before you buy. Are you opening YouTube and leaving a playlist on screen, or are you using the Mac as an encoder that sends a live feed to YouTube? Are you looping a pre-rendered file, or switching among several sources? These are different workloads. For a video-file loop sent through a production workflow, see the FFmpeg approach to looping a worship video without re-encoding; it concerns a specific method, not a general guarantee about a Mac mini.
Think about the playlist and playback workload
A playlist can mean different things. One reader may mean a YouTube playlist opened in a browser. Another may mean a local folder of prepared tracks or videos that software sequences and streams. A third may be describing a static video loop that is sent to YouTube Live. Before comparing computers, write down which one you mean and which application is responsible for each step. Otherwise a hardware comparison can answer the wrong question.
For a browser playlist, the Mac is only one part of the chain. You need to assess whether the playlist behaves as expected in the account and browser you intend to leave running, whether the browser remains available, and whether the machine and network stay in the required state. Current platform controls and settings can change; the sources in this comparison do not verify the exact YouTube autoplay conditions or macOS sleep configuration for your case. Check the current official guidance and test the actual browser session rather than relying on a general assurance.
For a locally assembled playlist or a live encoder workflow, the media files, ordering and transitions also need attention. A faster or newer processor will not necessarily fix a malformed list, an abrupt transition or a file that software cannot read. If the order itself is important, the guide to keeping an FFmpeg playlist in the intended order is more relevant to that failure than a chip comparison. Separate the source-preparation problem from the playback-device problem.
Network choice deserves its own check. Both specifications list Wi-Fi 6E and Gigabit Ethernet, so the M4 does not add a listed wired connection advantage over the standard M2. If the Mac will sit near the router, testing a wired connection may help you distinguish wireless instability from other causes. It still cannot guarantee continuity: the connection beyond the home network, service interruptions, browser behaviour and YouTube's own handling remain outside the processor specification.
Also consider whether you need to see the playlist locally. If you are simply broadcasting one already prepared video file around the clock, a computer left on for that task may be more than you need. If you need live controls, local editing, other applications or a visible display, a Mac mini can serve a broader purpose. The point is not that one workflow is universally better; it is that the right purchase follows from what you need to operate, not from assuming a newer decode line solves every interruption.
Compare the actual configuration, not just the chip
Model names conceal important purchase details. Check memory, storage, ports, condition, warranty and the seller's exact product description. Apple's standard specifications identify the processor and capabilities, but they do not tell you the price you will actually pay in your market or whether a particular sale is good value. Prices change by region and retailer, so compare current listings directly rather than relying on an old figure.
Storage matters if the Mac will hold local media, logs or other work; memory and processor capacity matter more if you will run several applications alongside playback. If the machine's only role is a browser with one playlist, extra capability may go unused. If you will also edit video or use the computer for work during the day, those tasks are legitimate reasons to assess the newer system independently of the streaming claim.
Power figures are often tempting shorthand for the cost of leaving a computer on. Apple's power-consumption page reports the M2 at 7W idle and 50W CPU maximum for a configuration with 24GB unified memory and 2TB SSD. For a configuration with 16GB unified memory and 256GB SSD, it reports the M4 at 4W idle and 65W maximum. These entries identify different configurations; the M2 label says “CPU Max” while the M4 table says “Max”. They are not measurements of YouTube playback and should not be treated as a like-for-like test or as a forecast of your electricity use.
Apple also gives maximum continuous power ratings of 150W for standard M2 and 155W for standard M4 on their respective technical pages. Those are product electrical ratings, not typical streaming consumption. The more useful comparison for your budget is a real-world measurement of the configuration you own or intend to buy, measured during the task you actually plan to run. Do not infer that the M4 will cost less to operate from the idle figures alone, or that either table entry predicts your bill.
Apple's power consumption and thermal output table is the source for those specific figures and configuration labels. Check it alongside the two model pages, and note the configuration printed next to each value before comparing. If your choice depends on electricity use, measure at the wall during the intended workload over a representative period and use your own tariff; the published figures do not supply that answer.
Test the setup before buying for continuity
If you already own an M2, start with a test rather than an upgrade. Use the exact playlist, browser, account, display arrangement and network you plan to use. Keep a simple record of when playback stops and what was happening: did the playlist advance, did the browser show a prompt, was the network unavailable, or was the Mac asleep? A specific observed failure gives you something to fix; “it needs a newer chip” is only a guess until linked to an actual constraint.
A useful test should cover the failure modes you care about, not only the first few minutes after pressing Play. Verify the intended sequence, check whether playback advances, and revisit the setup after the computer has been left unattended. Test your recovery plan too: if the browser or network needs attention, who notices, and how will the channel resume? This is not a formal benchmark and should not be reported as proof that the computer will always run. It is a practical way to discover whether your particular arrangement is suitable before spending money.
Do not assume the display sleep setting, system sleep setting and browser playback behaviour are one control. They are separate parts of the setup, and the current exact controls should be checked in Apple's and YouTube's official guidance for the software versions you use. This comparison does not verify current setting names or autoplay restrictions, so it would be misleading to offer a fixed sequence of clicks as though it applies to every macOS and account configuration.
If a test shows buffering, compare wired networking with Wi-Fi and inspect the actual connection before blaming the processor. If it shows the playlist stopping after an item, check the playlist and playback behaviour. If the Mac sleeps, investigate the relevant current macOS settings. If a production tool fails to advance files, inspect that tool's queue or playlist. Changing one factor at a time makes diagnosis clearer than buying an M4 and hoping the symptom disappears.
A local computer is useful when you need hands-on control, other Mac tasks, or a workflow built around software running on that machine. If your main requirement is simply to keep an uploaded file broadcasting while your own computer is off, that is a different operating choice. Compare it on the basis of file format, channel workflow, monitoring needs and recovery expectations; neither route removes the need to check YouTube's current rules and the suitability of your content.

FAQ
Is a Mac mini M2 enough to play one YouTube playlist?
Apple documents a video decode engine and support for common formats on the standard M2 Mac mini. The cited specifications do not establish an M4 advantage for playlist continuity, but they also do not guarantee that a browser session will remain playing unattended. Test your actual playlist and setup before relying on it.
Does the M4's AV1 decoding make a YouTube playlist smoother?
The M4 specification lists AV1 decoding and the M2 specification does not. That establishes a format capability, not which format YouTube will serve in your session or how smoothly a particular playlist will play. No controlled comparison in the available sources demonstrates a continuity or smoothness benefit.
Which Mac mini uses less power during continuous YouTube playback?
The Apple power table gives figures for different M2 and M4 configurations, and those figures are not YouTube playback measurements. It would be misleading to use them as a like-for-like result or predict your electricity cost from them. Measure the configuration and workload you plan to use if operating cost is central to the decision.
Should I upgrade from M2 to M4 just to keep a channel running?
The documented specifications alone do not support that upgrade decision. First identify whether the problem is playback state, playlist order, network reliability, sleep behaviour or a separate encoding workload, then test the relevant part of your setup. Consider the M4 for other work you need it to do, rather than treating AV1 support as proof of uninterrupted playback.
