An M6 iMac update does not confirm a 27-inch iMac comeback. Near-term reporting describes a 24-inch refresh; reports of experiments with larger displays are a separate possibility without a confirmed size or release date.
If you need more workspace, compare today’s separate-monitor options instead of planning around a promised 27-inch launch. If 24 inches already suits you, watch for confirmed M6 configurations and relevant tests. Reporting distinctions were reviewed on 12 October 2026; the current Australian setup prices below were checked on 10 October.
Could Apple bring back the bigger all-in-one?
The most interesting clue is that Apple has reportedly kept experimenting with larger displays and more powerful processors for the iMac. In its 8 March report, 9to5Mac attributed that information to Bloomberg’s Mark Gurman. It described a possible higher-end direction beyond the update planned for this year.
That makes the idea worth watching for people who loved a large screen and a computer in one unit. A roomier all-in-one could keep a photo, its reference and editing controls visible together, while retaining the tidy setup that draws buyers to an iMac. Those are potential benefits, rather than features tested on a new model.
The report did not pin down 27 inches or a launch date for that larger machine. A 27-inch iMac is therefore a useful way to describe the reader’s wish, rather than a size established by the reporting. What gives the wish substance is the reported work on larger displays and stronger chips.
M6 iMac release date: why late October matters
Gurman’s 8 October Bloomberg report says Apple plans a second October launch on or around Tuesday 27 October, including an iMac with M6. That is a more specific window than the late-October-or-early-November schedule discussed by 9to5Mac on 30 September.
The model described in earlier reporting is a refreshed 24-inch all-in-one. MacRumors’ 23 August coverage points to M6 and new colours, with the overall design largely retained. Read together, the reports give buyers a near-term chip update to watch and a separate, longer-term possibility of a larger design.
Pause a non-urgent purchase until the reported window passes. Then compare the actual Australian configurations, pricing and first application tests against any M4 offer you are considering.
Treat the reported iMac release date as a launch window to watch. Australian ordering and delivery dates are separate details to check when the product appears locally. If your current computer has failed and work cannot wait, compare the available options against that immediate need.
Would 27 inches mean fewer windows to hide?
Imagine editing a portrait with its reference beside it, or writing with research open next to the draft. The useful upgrade is being able to see those things at a comfortable size without repeatedly covering one with another. A larger display can help make that arrangement practical.
The current iMac has a marketed 24-inch, 4.5K display; Studio Display is a separate 27-inch, 5K monitor. Size, resolution and scaling influence what fits and how large text appears. The diagonal alone does not predict usable workspace.
Before buying, try two of your everyday windows side by side on a display you can inspect. Keep text at a size you would happily read for an afternoon. If the only way to fit everything is to make it uncomfortably small, the setup has missed the point.
Also measure the desk. Apple lists the current Studio Display with its tilt-adjustable stand as 62.3cm wide and 16.8cm deep. Leave space for your keyboard and a comfortable viewing position. These are dimensions of today’s monitor, not a prediction of a future all-in-one.
Will M6 make the difference you feel?
Apple has already introduced M6, initially in Mac mini. Its August announcement describes a 12-core CPU and 12-core GPU, with changes aimed at creative work and on-device AI. That gives the coming desktop a concrete chip platform to build on.
For the M6 iMac, the useful questions are closer to your working day: will a batch of photo edits finish sooner, will a demanding project respond more smoothly, and which memory configuration suits your apps? The final machine and application tests will give those questions a better answer than a chip name alone.
If your present Mac is quick enough but windows feel cramped, processing speed may leave the main frustration untouched. If the screen suits you and repeated rendering or compiling holds you up, a faster chip could be the change you notice most.
Write down one task that makes you wait and one screen arrangement you wish you could keep visible. That simple shortlist makes a launch easier to judge. You can look for evidence about your task instead of treating every specification as equally important.
What does a 27-inch desk cost in Australia?
Here are three current Apple options to give the waiting decision a real budget. These are Australian prices checked on 10 October, not a forecast of the M6 iMac price. The monitor below uses standard glass and a tilt-adjustable stand.
| Current setup | Apple AU price | What it gives you |
|---|---|---|
| 24-inch M4 iMac, 8-core CPU/GPU, 16GB/256GB | From A$2,399 | Integrated 4.5K desktop; keyboard and mouse included |
| M6 Mac mini, 16GB/256GB + 27-inch Studio Display | A$4,048 combined | Separate computer and 5K monitor; add input devices if needed |
| 27-inch Studio Display + your compatible Mac | From A$2,599 for the display | Keep the computer; change the workspace |
The two-piece total is A$1,449 for the base Mac mini plus A$2,599 for Studio Display. It buys a different screen and computer combination from the entry iMac. It is not a comparison between equally specified all-in-ones, and it excludes any keyboard or pointing device you still need.
If you already own a suitable Apple silicon Mac, the display-only route changes the calculation. Check the exact model and operating system first: Apple lists supported Apple silicon Macs running macOS Tahoe 26.3.1 or later for the current Studio Display. Do not assume an older Intel iMac qualifies.
A separate setup lets you keep the monitor when replacing the computer later. Decide whether that flexibility or an integrated design matters more at your desk.
M6 iMac: what announcement would make you buy?
If a 24-inch desktop already suits your screen needs, watch the M6 iMac announcement for the configuration and price that improve your actual workload. New colours could add appeal, but the daily benefit should come from the work you do.
If your priority is a 27-inch iMac, decide whether you specifically want the integrated design or simply a larger workspace. The former gives you a reason to follow longer-term reports; the latter gives you current options to inspect and price.
Wait for the change your desk actually needs.
Set the end of October as your next decision point. If the announcement solves your main frustration at a sensible local price, investigate it. If it focuses on a faster 24-inch machine while you want more screen space, you can price a separate display setup without turning the next rumour into another indefinite wait.

FAQ
Q. Will the M6 iMac bring back 27 inches?
The near-term reporting describes a 24-inch refresh. Separately, 9to5Mac’s March coverage describes experiments with larger displays and stronger processors, without an exact size or date. That supports following a larger all-in-one, rather than planning a purchase around a promised 27-inch launch.
Q. Is the iMac release date also an Australian delivery date?
No. Bloomberg’s report points to a launch around 27 October. Check the Australian ordering and delivery details separately when the product is listed; use the reported window as your next comparison point.
Q. Should an M4 owner upgrade straight away?
First identify what would improve your day. If the current computer handles your work comfortably, wait for application tests before replacing it. If screen space is the issue, inspect a larger display arrangement and check compatibility before paying for a new computer.
