macOS has a hypervisor framework built into it today. The version of Parallels Desktop currently available in the Mac App Store uses it, and a modified version of that app is probably what was demoed today.
The Parallels Desktop version sold outside the app store, and VMware Fusion, both use their own hypervisors which are not dependent on the one included in macOS. In spite of the common name, the Mac App Store version of Parallels Desktop is really an entirely different application than the one Parallels sells outside the App Store.
This was in my earlier reply to the person I was answering.
Thank you. The most annoying thing about Parallels in the App Store (Desktop Lite) is when it went from free to paid when Corel bought Parallels. I stuck with 1.3.3.
 
That's what I'm wondering as well. The way Craig described it, that's the way it sounded.
I am speculating that the Rosetta 2 interface is also exposed via hypervisor framework hooks to allow those that support the HV FW to work without change. That might just be Parallels in HV FW mode. Virtual Box uses its own hooks directly into the chip virtualization instructions.
 
My iMac 2012 is no longer supported😭

I guess I'll have to get the new iMac, oh hang on...😂

Finally getting rid of that unhelpful extra decimal. They can better follow the version numbers of iOS.

Such as: 11.3.2
Instead of 10.15.3 Supplemental 2

It was ridiculously long and confusing.

Yeah, it was useful when you could virtualize Linux or macOS free and then that just vanished silently with the update so I abandoned it then and will just stay with Fusion. What comes next will be interesting. Since I have to support a whole bunch of Windows Intel computers for work, I'm not sure an ARM Mac remains a viable product for me as a work tool.
 
Give them credit for failing badly? ARM and Windows has been a marriage made in hell.
I’m not sure you can claim it a failure since it’s simply another option for hardware manufactures.

Also my post had nothing to do with successful or failure but simply pointing out to the post I replied to when the said “windows would follow suit”, is that windows already has it. There’s nothing to follow.
 
One of the things I see coming and have said it many times is that macOS system updates will be treated just like iOS and iPadOS, meaning once you upgrade and Apple stops signing it there's no way of going back. I see this happening to all the ARM based Macs in the future. Hope I'm wrong.

I'm willing to give macOS 11 a fair shot. Hopefully optimizations and stability can be ported over from the mobile OS'es

I'm a little scared of that.

I feel like Desktop/Workstation applications have a longer lifespan than mobile Apps.

I work in the automotive industry where it is standard to expect a supplier to be able to to re-create the development environments (including all desktop applications) for at least 8 years after launch of the product. People put a lot of effort into archiving Windows and Linux images to comply.

It also means that any particular version of a desktop application needs be taken out of the drawer if necessary and fired up, even a decade after the project started and even if it's not supported by modern operating systems. This potentially means even graphical UI apps that are no longer supported on current operating systems, which is fine, if you are still able to install older OSes.

If it's impossible to make sure that you can install macOS it means automatic non-compliance and a red flag for entire industries.

Even Windows fan boy Paul Thurrott says Windows on ARM is an unusable disaster in terms of performance. Microsoft has done NOTHING like what Apple is setting out to achieve here anyway. Windows doesn't already have it - you are clutching at straws.

Downloading now too.. maybe the file names are still 10.16 (says it also here) but the os 11.0. Could also be that version number changes in a later beta. They always have a newer beta running on then on WWDC, then there is available for download at first. I believe iPadOs 13 dev beta, was still called iOS 13 for a few beta's
 
Hmmm. Spackling the holes and a fresh coat of paint is what I say about Big Sur. Mail, Messages (true, real-time, multi-device sync) and Preview leave a lot to be desired.

Is your download superslow too??

I couldnt watch the mac part of the keynote, do intel users get OS virtualization or just the ARM ones?
 
What my mid 2012 MBP is not supported? It runs Catalina. Looks like a small patch will enable it like how I run El Capitan on my MacPro 1,1.
 
I'm sitting here at only 2 GB/9.5 GB downloaded and macOS is reporting that it will take an additional 6 hours to download the new macOS....gotta love WWDC days!!

Problem is, the entire advert was for what they had changed in the OS to how it looked. Where was the meat? the performance increased, dealing with problems and blights behind it. Most people who care about an MacOS release really want 'meat' rather than this advertising nonsense.

TBH, the gaming demo that they showed off wasn't all that impressive. Tomb Raider looked baaaaaaaaad....the shadows were low res, the details were suboptimal. I guess they were running the game at 1080p and low settings to get a decent framerate?

If you thought gaming on Mac was bad, games running on Rosetta 2 to emulate x86 architecture is going to be even worse.
