Sonos speakers join their own wireless network and keep playing music sent straight to them, so the source device can be turned off or leave the house entirely. A Mac-based setup routes every stream through the Mac itself: if it sleeps or switches off, the audio stops. That one structural difference decides which option actually suits you.
This is not really a contest between two products. It is a question of what you already own, where you listen, and whether you need speakers that carry on regardless of what your Mac is doing. Below is the honest version of both routes: what Sonos actually buys you, when a Mac already covers it for free, and how the Mac-based setup works if that is the one you decide you need.
What actually makes Sonos different from a Mac-based setup?
Sonos speakers do not receive audio the way a normal Bluetooth or wired speaker does. Each one joins Sonos's own network, either over your Wi-Fi or a dedicated mesh the speakers form between themselves, and music is streamed or cast directly to them. Once that stream is playing, the phone or Mac that started it can be switched off, put to sleep, or carried out of the house, and the speakers keep going. The source device only has to be involved to start or change the music, not to keep it playing.
A Mac-based setup works the opposite way round. Whether you use macOS's built-in Multi-Output Device or an app that manages it for you, every speaker in the group is receiving audio the Mac is actively sending out in real time. There is no independent network, no local storage on the speaker, and no handoff. The Mac is the source for as long as anything is playing, full stop. Put it to sleep, close the lid, or switch it off, and the audio stops immediately across every speaker in the group.
When is a Mac-based setup the smarter choice?
If you already own the speakers or devices you want to combine, and you mostly listen while sitting at the Mac or somewhere it stays awake anyway, a Mac-based setup is very hard to beat on price. macOS can already send one audio stream to several outputs at once through Audio MIDI Setup, a free tool built into every Mac, so there is no hardware to buy at all. You are using speakers you already have, driven by a Mac that is already on.
This suits a desk setup, a small studio, or a room where the Mac genuinely stays powered on for most of the day far better than it suits a whole house. The moment the Mac goes to sleep to save power, which most Macs do automatically after a period of inactivity, the audio stops. That trade-off is fine if you are sitting right there when it happens. It is a real problem if you were expecting music to carry on playing in a room three doors away.

Download for MacWhen is Sonos actually worth the money?
Sonos earns its price when you need rooms to work independently of any one device. A speaker in the kitchen and a speaker in the living room can each be controlled from a different family member's phone, playing different music, without either phone needing to stay on or stay home. That kind of independent, per-room control is not something a Mac-based setup can offer, because everything still runs through one machine.
It is also the right call if you want music to keep playing overnight, while you are out, or in a room the Mac never sits in. Buying dedicated speakers for every room is a real cost, usually several hundred pounds once you cover more than two rooms, but you are paying for speakers that do not care whether any particular computer or phone is switched on.
How do you combine speakers on a Mac in practice?
The built-in route is Audio MIDI Setup, found in Applications > Utilities. Click the plus button in the bottom-left corner, choose Create Multi-Output Device, then tick every speaker or display you want to include. macOS will now send the same audio to all of them whenever that device is selected as the output.
The trade-off is the interface, not the audio. A Multi-Output Device built this way loses a working volume slider: because the group is not a real device with its own volume, macOS has nothing to send a volume instruction to, so the on-screen slider and your keyboard's volume keys grey out. You end up back in Audio MIDI Setup, adjusting each speaker's own level by hand every time you want it louder or quieter.
Chorus builds on the same Multi-Output Device support already in macOS, so it is still routing through the Mac in exactly the way described above; it does not create an independent network for your speakers. What it changes is the day-to-day handling: Outputs and Groups let you combine devices from a menu bar icon rather than Audio MIDI Setup, one volume control moves every device's own level together while keeping any balance you set between them, and Keyboard Shortcuts and Auto-Switch let you jump between groups without opening a settings panel. It is $4.99 once, with every feature free to try for 30 days, no account or card details needed, and one licence covers up to three Macs. None of that changes the underlying dependency on the Mac being awake.
So which one do you actually need?
This is not really Mac versus Sonos. It is a question of whether you already have what you need. If the speakers exist, the Mac is nearby and awake for most of the day, and you are not trying to run independent music in five rooms at once, a Mac-based setup covers it for the price of an app, or for free if you are happy adjusting each speaker by hand. If you need rooms that keep playing without the Mac involved at all, or several people controlling different speakers from their own phones, that is the moment dedicated hardware like Sonos earns its cost.

Frequently asked questions
Does a Mac-based multi-room setup work the same way as Sonos?
No. Sonos speakers join their own wireless network and receive music directly, so they keep playing even if the source device is switched off or leaves the house. A Mac-based setup routes every stream through the Mac itself, so if the Mac sleeps or is switched off, playback stops.
Does Chorus work like Sonos?
No. Chorus groups your Mac's own outputs so they play as one, with a single volume and shortcut, but the audio still runs through the Mac. It does not give speakers their own independent network the way Sonos does, so if the Mac sleeps or is off, playback through Chorus stops just like any other Mac-based audio.
When is Sonos worth buying instead of using a Mac-based setup?
When you need speakers to keep playing independently of any single device, when different family members want to control different rooms from their own phones, or when the source device is not reliably switched on, such as a phone that leaves the house. Sonos speakers do not depend on any one device staying awake.
How do I combine several speakers into one output on a Mac?
Open Audio MIDI Setup, click the plus button in the bottom-left corner, choose Create Multi-Output Device, then tick each speaker you want in the group. macOS will play the same audio to all of them at once, though the group's volume control is limited.
Is a Mac-based multi-room setup cheaper than Sonos?
Usually, yes, if you already own the speakers or devices involved. A Multi-Output Device is a free macOS feature, so the only cost is a Mac staying near power and awake while you listen. Sonos means buying dedicated hardware for every room.
