What I am saying is there is still the possibility the iMac would get updated just as a silent update.

They've done that before, updated Macs right after the keynote, without actually mentioning those Macs in the keynote. Plus, the 6-core MacBook Pros were silent updates.
I initially dismissed your post and another similar post, but given the 9th Gen CPUs are going on sale tomorrow, next Tuesday and a silent update is actually feasible. I would think Apple would want to tout the iMacs increased power, better screen, etc,, but since there has been zero recon on the iMac, you may be right. Perhaps the 30th is the most logical, but a silent update could be in the cards.

It's too late in the cycle to release anything even later than October 30 so Apple would have to silently release anything they deem unworthy of fitting into a packed presentation on the 30th on Tuesday 23rd - I think it would be counter productive to even tease a 2019 Mac Pro but there's enough reason for Apple not to do a song and dance with the iMacs and Mac Mini, especially if they remain externally the same.

So if Apple are doing anything of the sort they'll potentially major on the remaining Macbook releases - sure to be the biggest single selling Macs in the holiday season.

Even a release delayed till the Friday of that week to squeeze into the Holiday quarter for results purposes would make it November 2, the day after the results call. I don't believe any new Mac has been released in November - Mac Pro and iMac Pros had the feeling of being released to meet a promise (of being out in December of the relevant year).

Perhaps Apple wanted to do some extra press on whatever form factor the MBA replacement takes up - even if it just looks like the 2017 nTB MBP.

Look on the bright side. Maybe they have a newsworthy machine coming up?

As previously mentioned, I'm expecting a 13" Macbook (to replace the Macbook Air) and perhaps Apple will pull a proverbial rabbit out of the hat with a (one last thing) 15" Macbook - both machines to emphasise battery life over sheer horsepower while doing away with the Touch bar.

all I meant to say is that we can expect a big iMac update, and it's surprising there's still doubt over it.

I'm not so sure how "big". Could be just a minor speed bump. Or, could be the ole coming early next year bla bla..Hope for at least the 6 core option. I don't think a major case/display redesign quite yet. I hope I'm wrong.

could the chopped up apple maybe refer to a modular mac of some sort?
That’s the vibe I’m getting. I wonder if they will incorporate the iPad Pro into the Mac ecosystem via USB-c. The ability to use the iPad as an input device on a Mac opens up a lot of possibilities.

Kuo stated significant display performance upgrade so i'd bank on that easily given he knows more than we do. Display upgrade could mean many things(HDR, 120 Hz, new form factor..etc)

I tend to think Apple might split the difference and make a 14” MacBook. So we end up with:
12” MacBook Core Y-5w
13” MacBook Pro Core U-28w
14” MacBook Core U-15w
15” MacBook Pro H-45w

To me, 13” or 14” is a quarter toss. I offer it up as it provides more separation between the 12” MacBook and a 13” MacBook and lessens confusion for users between a 13” MacBook and 13” MacBook Pro.

In my opinion, a 13" Macbook could be very easy to engineer as it could be based on the non touch bar Macbook Pro but with cheaper innards. They could create one with 4 USB-C ports with ease.

Similarly, a 15" Macbook has to be easy to engineer too based on the same principle. Apple may even have had non Touch Bar designs in waiting.

The rumours of 14" (and 16") SKUs have gone away for now (still reckon that it could happen but with the Pro models).

In pure marketing terms a 14" model might overshadow the 'smaller' 13" models. Plus we're either thinking bigger bezels (like the MBA!) or bigger screen with more pixels which is runs counter to a lower powered machine unless it's non-retina (which isn't going to happen).

I sincerely doubt Apple will reuse the nTB chassis for the MacBook. Apple wants to tout a slimmer chassis patterned after the 12” MacBook, along with terraced batteries, et al. I would expect no more than two USB-C ports (Gen 2) and an audio jack, 802.11ac/BT 5.0, 16GB max LPDDR3 DRAM, 1TB NVMe max. A 14” display at 2560x1600 would be 215DPI versus 232DPI, which is marginally less, but still acceptable. Besides, I believe Apple defaults the 13” MacBook Pro to 1440x900, but leaving the 14” @2x would be easier on the iGPU, especially for a UHD620.

The 13” MBP cannot be overshadowed by a 14” MB, because it will not have the same capabilities expansion-wise. It will also be as small as Apple can make it, as it is using the 12” MacBook as its design template/inspiration.

You've forgotten the removal of font smoothing in Mojave which reduces the impact on iGPU at the expense of looking poor on non retina displays. This move has convinced me that 2018 Macs will either come with retina display or be capable of driving one with acceptable performance. And Apple have rebadged the same design before, especially where the name Macbook and Macbook Pro has been concerned.

A shift to 14" would be a major engineering feat and something I'd say is better reserved for the Pro models and not the 'economy' models, even if we are talking about probably the biggest selling single Mac SKU year on year.

The 13" Macbook Pro is 2560x1600 retina which is a high quality analogue of 1280x800. It's fairly easy to believe that the non touch bar 13" Macbook Pro morphs into the replacement for the MBA. It has to drop $200 but if Apple went for the i5-8265U and lost the Thunderbolt controllers they could get close to the $999 or $1099 band because things like the screens are being bought in cheaply through economy of scale with the Touchbar Macbook Pro.

The old MBA was 1440x900 which is actually the analogue resolution of the 15" Macbook Pro (native resolution 2880x1800). I'd take an interest in a 15" Macbook depending on the specs.

Not really. Since 2012 any given iMac price tier has had a 16-month average/20-month median update interval. The 371 day average posted by MacRumors is just an illusion caused by the clock resetting whenever -any- iMac of any tier had an update or price cut. If Apple sticks with synchronized refreshes across all tiers as in 2015 and 2017 then a 2018 update would actually be early by Apple's recent trend. Combine that trend with the unusual lack of credible rumors (just 1?) and I wouldn't be surprised if this event is for the iPad/Air/Mini only.

I'm really hoping I'm wrong and we get a 2018 iMac update before I finish grad school and loose my educational discount, but I don't think we could call an iMac update 'Late' until the 2017s hit 20 months old in Feb 2019. Apple won't even set a record for lateness unless they pass 25 months in July 2019.

Apple did not have to engineer a completely new display for the iPhone XR, but they did it anyways and at a lower resolution than users expected, but they did. Why? Because they knew the investment would be worth the reward.

This new MacBook will come with a Retina Display, that I have no doubt. What I am saying is that at 14” a resolution of 2560x1600 would be the most likely and might be set to “Best for Display” of 1280x800@2x (true Retina), and not to a “scaled” resolution as the 12” MacBook and the MacBook Pros are now. A 14” display in a MacBook style tapered case would not be a major feat at all, its essentially a 14” MacBook or a 14” MacBook Air.

While I can get on board with Apple using the 13” MacBook Pro display, I do not see them using the nTB chassis not giving it more than two USB-C ports or a single TB3 port. I can also see it using the T1 chip to give users access to Touch ID.

Problem is, that's a lower density - if Apple change the density of a display they change it upwards (as with the Xs). They also change the size too more often than not.

When I was discussing the logic behind the Mac range going 12", 14", and 16" some years ago I would have then suggested relative analogue resolutions of 1280x800 (2560x1600), 1440x900 (2880x1800), and then 1920x1080 (3840x2160). This entailed the 14" and 16" machines going a bigger, heavier case for power, GPU, and battery life. Instead, of course, Apple went down the 'stealth fighter' line - ever thinner - plus the bizarre advent of the Touch Bar - and the introduction of the much maligned butterfly keyboard.

The current 13" nTB MBP challenges the MBA's title as the thinnest and lightest Mac laptop - they are virtually the same weight, and yet the nTB MBP is smaller in nearly every dimension.

Cost reducing the MBA replacement would surely knock out any prospect of a TouchID or T2 CPU, I've already suggested doing away with Thunderbolt and using a cheaper CPU - the i5-8265U would be capable of driving the retina display with Mojave's removal of font smoothing.

Apple won't even set a record for lateness unless they pass 25 months in July 2019.

There's been a couple of examples of iMac delays, the most recent delay I put down to the lack of suitable Intel CPUs. Yes there have been times when the 21" got a refresh and the 27" didn't or vice versa. I'm not going to fully research that at the moment.

Famously the Broadwell CPUs were messed up by Intel and left Apple having to wait for Skylake. I've written about that elsewhere so I won't go on about it. There's basically no other reason for Apple not to adopt an annual October refresh for the iMac otherwise.

The 2017 super refresh was in part due to missing the October 2016 refresh in which only laptops were unveiled and we're over a year later with 6 core CPUs out. It's insane for Apple to miss out on 6-core machines and recent articles about demand dropping off may be a factor.

Here's a copy of my research to save you the trouble. Now that you mention it Apple hasn't ever skipped a CPU generation aside from the Broadwell/Skylake split release. Huh.

CPU . . . . . 3rd . . . .4th . . . . . . . . . 5th/6th . .7th
GPU . . . . . GT 6xx. . .GT 7xx/R9 M2xx. . . . R9 M3xx . .RX 5xx
$1099 21.5" . 03-2013 -> 06-2014 ------------> 10-2015 -> 06-2017 {15, 16, 20}
$1299 21.5" . 10-2012 -> 09-2013 ------------> 10-2015 -> 06-2017 {11, 25, 20}
$1499 21.5" . 10-2012 -> 09-2013 ------------> 10-2015 -> 06-2017 {11, 25, 20}
$1799 27" . . 10-2012 -> 09-2013 ------------> 10-2015 -> 06-2017 {11, 25, 20}
$1999 27" . . 10-2012 -> 09-2013 -> 05-2015 -> 10-2015 -> 06-2017 {11, 20, 5, 20}
$2299 27" . . 10-2012 -> 09-2013 -> 05-2015*-> 10-2015 -> 06-2017 {11, 20, 5, 20}
$2499 special . . . . . .10-2014 -> 05-2015* {7}
*Late 2014 5K price cut.


Average update interval: 16.1 months.
Median update interval: 20 months.

The numbers do look better if one instead starts at 2011 or earlier, but back then there were only 4-standard configs plus an educational model.

Anyway, I can think of two logical reasons we didn't see 6-core RX 500X iMacs along side the MBPs.
(a) Apple was waiting on 9th-gen CPUs for the 5K lineup and chose to delay the 4K update to keep releases in sync.
(b) AMD messed up this year and Apple is committed to waiting on RX 6xx GPUs coming 2019.
Assuming either is equally likely I'm guessing 50% chance of new iMacs on the 30th.

...although if you want to be super optimistic and believe pigs can fly there is also:
(c) Apple has a special anniversary iMac with an Nvidea RTX 2070 which is why Nvidea hasn't released Mojave drivers yet.

(Edited to clarify I don't think (c) is a logical reason and was included as an attempt to offset my prior pessimism)

You have some good points and then you had to throw in C and it went completely south. I would not be surprised if SJ wrote in his will that Apple cannot do business with NVIDIA ever again.

ITs for iPhone Xr...get over it.
Now, its seems in the cargo that is going with products for hands on, a large product was under the curtain with the shape of an imac...so a redesign imac can be shown...OR since the logo for the next event is "There's more in the making" could be the next Apple Display...so we will get imac redesign or sneak peek for the apple display, i hope for both TBH

According to Geekbench the 2017 i7 iMac has the fastest single thread speed in mac history. Single thread speed is what makes a typical workstation snappy to use. This iMac's multithread speed is around 10% or so less than the 6 core 2018 i9 MBP. If you have a heavy multithread workload, you have various iMac Pro options for that. Otherwise you'll probably better off with the faster single thread speed. I doubt very much anyone is going to produce a mac compatible 6 core desktop processor that beats the 4 core 7700K's single thread speed in the near future.

Also, Apple would probably have to implement improved thermals in the regular iMac, similar to the iMac Pro, to accommodate a 6 core processor.

If you're waiting to buy the regular iMac because you don't like the chin/bezels that's understandable but it's anyone's guess when that may happen. They didn't change it for the iMac Pro. However waiting for a better processor is unwarranted IMHO.

For the record I bought the 2017 i7 iMac when it was released and have enjoyed it ever since.

Since then Intel released the 8600k, 8700k, 8086k, 9600k, 9700k, 9900k all with slightly better single and much better multicore performance (https://browser.geekbench.com/processor-benchmarks -> missing 9th gen because they were released today). The 7700k is still a good processor but it's no excuse for not updating the iMac.

If your 7700k does everything you need great, there's no need to upgrade but for someone buying a new iMac in 2018/2019, it better not come with the same hardware for the same price.

Also, with mainstream processors having more and more cores, more applications will try to make use of those ressources and it's probably a matter of time before 6 or 8 core becomes more useful even for regular users.

I doubt very much anyone is going to produce a mac compatible 6 core desktop processor that beats the 4 core 7700K's single thread speed in the near future.

However waiting for a better processor is unwarranted IMHO.

This is just incorrect. Intel has several i7’s and i9’s which have better single thread performance than the 7700K. The 2018 MBP does not have desktop-class processors. They are not the same as the 8700K and 9700K for example, and a new iMac would certainly have the unlocked K versions unlike the MBP. Plus, more programs today utilize multipule threads, so there are a lot of people who will benefit from a core increase.

If Apple does do an iMac update, they would never keep the 7700K. The 8th gen (and 9th gen) cpus are better for almost every task, and Apple would look very dated if they stuck with 2-year-old CPU’s in a 2018/2019 product.

@Gimnet1

You're right, on face value, but not if you take into account the power and thermal constraints of the iMac, the same goes for most macs. Faced with increased competition and their inability to get more IPC from similar process nodes, Intel has resorted to increased power consumption to get better performance. I'm not sure these processors will provide the increased performance you expect if used by Apple. Time will tell and I actually hope you're proved right.

I'm not so sure how "big". Could be just a minor speed bump. Or, could be the ole coming early next year bla bla..Hope for at least the 6 core option. I don't think a major case/display redesign quite yet. I hope I'm wrong.

I think that predicting the iMac update is rather easy, given the roadmap of Apple's partners. It will most likely use the new 8-core Coffee Lake Intel CPUs (gen 9) and the new AMD Polaris 30 chips (which conveniently get released in November for everybody else)...
