NSImageInterpolationNone no longer works in Big Sur
As the developer of Seashore, using [[NSGraphicsContext currentContext] setImageInterpolation:NSImageInterpolationNone]; no longer works as expected in Big Sur on a Retina display. The exact build works fine in Catalina. Small images seem to be first scaled using Medium or High interpolation to 2x, then scaled use 'None' to the desired size - causing blurriness. This the code to display and scale the image: [[NSGraphicsContext currentContext] setImageInterpolation:NSImageInterpolationNone]; [image drawInRect:alignedRect fromRect:copy operation:NSCompositeSourceOver fraction:1.0 respectFlipped:TRUE hints:NULL]; Any ideas for a fix?

Big sur taking more than an hour to install
I have mac pro that was working on High Seirra OS, today I started installing Big Sur on it, the installation process was smooth until I reached this loading circle, this took much time the way that the total installation time is more than an hour and didn't finish until now, it keeps loading. Should I wait for more time or this means there is an issue? And if there is an issue how can I fix it?

Kindle Crash Big Sur Beta 10
Hi all. I recently upgraded to Big Sur Beta 10. Since then, my Kindle Reading App crashes. It opens but as soon as I open a book it crash and brings up a crash report. I deregistered, removed and reinstalled it but it behaves the same. It will download a book but as soon as it tries to open it, it will crash. Is this behaviour know under beta 10? Is there any work around? Thank you.

Hypervisor framework problems in Big Sur
I have 3 problems in this post. hv_vm_create() fails I recently got the BigSur beta (I'm on the latest) to try out some hypervisor app I've been working on, however hv_vm_create() - https://developer.apple.com/documentation/hypervisor/1441424-hv_vm_create fails. 2. Killed: 9 when signing with Hypervisor entitlements I figured Big Sur might be enforcing entitlements, so I signed it with the same entitlements from xyhve - https://github.com/machyve/xhyve/blob/master/src/xhyve-entitlements.plist (and updated it as per the documentation - https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_vm_hypervisor) but this time I was getting. Killed: 9 Do I have to request permission to use those entitlements? That's the conclusion I'm coming to because HypervisorKit just doesn't work; and nothing happens on macOS for no reason. 3. HypervisorKit in beta? This is what confuses me the most. Why are HypervisorKit functions that have existed since 10.10 in beta? And why does the d

Crazy behavior from open in Big Sur
In Big Sur, I noticed that the open command no longer distinguishes different copies of an application. For example, if I have /Applications/AppV1.app and /AppicationsAppV2.app, and AppV1.app is running, then open /Applications/AppV2.app is simply bring AppV1.app rather than opening AppV2.ap. I have to use the -n flag to open the second version. This seemed like a regression to me (I filed FB8806330 about it), but perhaps intentional, or at least justifiable. But now I've discovered a much worse symptom. If App.app and Bpp.app is another application by my company, then open /Applications/Bpp.app brings App.app to the foreground rather than opening Bpp.app. All the applications have distinct bundle identifiers. Indeed open -b com.Company.Bpp will also bring App.app to the foreground. This is just a crazy bug, right? Any ideas what it might be keying off? It can certainly tell the difference between our apps and, say, Safari. So I'm not sure why it can't tell our applications apart. And if any

SMB-Multichannel is incomplete or broken
I know this is a bit late in the Sonoma beta-program, but I wanted to ask here, since I got directed here by Apple support, even though it appears I got Sonoma-14.0 release a day before the non-beta users. And/or I want leave a marker for others with the same needs. I have a 2019 Mac Pro with a dual-port 100GbE ATTO card in it. I run Adobe Premiere, DaVinci Resolve and Autodesk Flame. I would like to do editing and color correcting 4K and 8K frame-based video. 8K video is 4.5GB/sec per DPX stream. (not Gigabit). I connect to a SMB server which is all flash, and runs SMB-Multichannel. This same NIC in a windows box can run 9GB/sec. but in the MacPro, it gets about 3GB/sec. if you run netstat, smbutil, or nettop (the builtin MacOS utility) it shows only ONE TCP socket talking to my server on port 445. This is the reason it goes no faster than 3GB/sec. Windows shows 8 or 16, whatever I set it to number of RSS channels, and goes full speed of the NIC. When is MacOS SMB-Multi-channel goi

Unable to Install Big Sur Beta 2
I have Big Sure Dev Beta 1 installed on an external USB-C SSD drive. Mac is a brand new 2018 Mac mini (most recent Intel model). Beta 1 works fine (well, for the purpose of beta testing anyway Big Sur Dev Beta #2 is out now. Software Update GUI Pane and CLI both see the new update, but I'm unable to downed/install it. Here is the error I see from running 'softwareupdate -d -a' from Terminal: 'Failed to download & prepare update: Error Domain=SUMacControllerError Code=7722 [SUMacControllerErrorPreflightPrerequisiteCheckFailed=7722] Failed to perform PreflightPrerequisite operation: com.apple.MobileSoftwareUpdate.preflight.error(Preflight):MSUPreflightErrorTargetIsNotSnapshotBooted(6) | The volume can not be used because it is not snapshot booted.'

vmnet Framework broken in Big Sur beta 6?
I am working on an emulator for some legacy hardware. I recently changed the emulator to use the vmnet framework for network access rather than the old Berkley packet filter (/dev/bpf) device. It works just fine in macOS Catalina. In Big Sur beta 6, the vmnet_start_interface completion handler is never invoked unless the call to start the interface failed. I've submitted FB8648370 to report this. Here's some sample code that demonstrates the problem. Compile it with -framework vmnet and run it with privileges via sudo. On Big Sur, it will timeout after 1 minute. vmnet.c - https://developer.apple.com/forums/content/attachment/f4a79dd9-f801-4171-b1d0-d62fdad38df0
