macOS 15 Rumored to Support Same Macs as macOS Sonoma, With One Possible Exception

[MacRumors]

Just hours before Apple announces macOS 15 during its WWDC keynote today, a proven leaker has revealed alleged compatibility details for the software update.

In a post on X, the leaker said macOS 15 will be compatible with all Apple silicon Macs with the M1 chip and newer, and all Intel-based Macs equipped with Apple's T2 security chip. If this information is accurate, macOS 15 would be compatible with all Macs that support macOS Sonoma, with one possible exception: the 2019 iMac.

macOS Sonoma is compatible with the 2019 iMac, which does not have a T2 chip, so it is unclear if that model will support macOS 15 or be dropped.

Here is the rumored compatibility list for macOS 15:

• MacBook Pro: 2018 and later
• MacBook Air: 2018 and later
• Mac mini: 2018 and later
• iMac: 2019 and later*
• iMac Pro: 2017
• Mac Studio: 2022 and later
• Mac Pro: 2019 and later

* iMac would be 2020 and later if a T2 chip is required.

Even if macOS 15 supports many Intel-based Macs, new on-device AI capabilities will likely be limited to Apple silicon Macs, which have a Neural Engine.

The leaker who revealed this information has a private account on X, so we have elected not to share its name or link to it, but they have shared accurate compatibility information and build numbers for Apple's software updates in the past.

What name will Apple use for macOS 15? That remains a mystery.

I guess we'll be finding out soon…

It's a hard life out here for us iMac fans. 😢

 

[Darren.h]

WOW! this is awesome. Now I can run out and buy a 2019 Mac Pro. Always wanted one. Too expensive new.

Mac Studio is a throw away Mac if it breaks. Not the Intel Mac Pro 2019.

Intel Lovers rejoice!

 

[cicalinarrot]

Those iMac buyers should have checked if their new computer had the Planned Obsolescence Chip 3000 before buying.

 

[Moukee]

So the 2017 iMac Pro has a T2 chip but the newer 2019 iMac doesn't?

 

[Moka Akashiya]

Strange, I expected that they would continue to actively remove support for Intel Macs. Perhaps they reconsidered this decision and decided not to rush. However, I’m sure they will still surprise us with the number of features that will be limited only to Apple Silicon.

 

[boak]

My guess is this will be the last macOS version for Intel Macs.

 

[Homy]

”That remains a mystery” is the longest name I’ve ever heard for macOS.

 

[brofkand]

Odd the iMac 2019 wouldn't have had a T2 chip. Why didn't they include it, when every other Mac model by then had it?

 

[MrGimper]

Be good if the 2019 16" intel gets support, as I plan to use that as my 2014 iMac replacement now I have my M3 Max 16"

 

[gank41]

Really happy my Intel Mac mini will still see updates this year!

 

[tomtad]

It’s called Redwood btw

Thank me later

 

[arkitect]

My little champ of a Mac Mini 2018 thanks you!

 

[Mr. Rod]

Shouldn't these posts be marked as potential spoilers? At this point we may have 80% of WWDC already revealed lol

 

[greenbreadmmm]

My guess is this will be the last macOS version for Intel Macs.

No way

Hmmm. That'll be interesting.

I mean, I always grab a pic of some horrible traffic in whatever California place to use as a desktop pic, because every new release of Mac OS these days is more awful than the last.

Live question for me, as I have that iMac too. It's the oldest one I still have and I hardly use it, was thinking of sticking Linux on it soon anyway so it can start its second life in earnest, but this would clinch it.

The other thing I was thinking of doing was giving it to my Dad, to replace his 2010 (!) iMac 27". I've tried to get him onto something newer before, but now in the year it looks like he's finally taking the bait, the bait's going off... He'd probably be happy with not being bothered about software updates but it gives me the heebiejeebies.

(IIRC old versions of macos get two more years of software updates, and possibly the odd extra one if it's for a really bad exploit. Is that right?)

 

[thebart]

We're going to have live leaks!! There'll be leaks of what people are going to say while Tim introduces them!!

 

[mabaker]

So the 2017 iMac Pro has a T2 chip but the newer 2019 iMac doesn't?

Apparently:

Glad it does, though. Love mine - best iMac ever released and so quiet.

 

[boak]

No way

I guess we will find out in a year

You might check out - Open Core Legacy Patcher from Dortania. I have upgraded several older Mac’s back to 2009 with a much later macOS.

I read somewhere that macOS 15 will be named “macOS Golden Gate”.

 

[Asbow]

Looks like it’s time to buy my old iMac Pro from my friend who bought it off me.

 

[Ian Howlett]

I’ll be pretty angry if my five year old iMac 2019 is already no longer supported. I deliberately bought a high spec model so it would last a long time. Planned obsolescence to this level is unacceptable.
