My situation is only the display sleeps the system is not sleeping the app is running it is a http server and i can access the pages served by the mac os app. but when the app tries to take screenshot when the display sleeps it is not working. this is my scenario.

Just to answer my own question now it is possible to do this with macOS 26 with custom vmnet network.

Apple asked me to use cgevent like this guard let cgEvent = CGEvent(mouseEventSource: nil, mouseType: .rightMouseDown, mouseCursorPosition: cgPoint, mouseButton: .right) else { return } // Create the synthetic NSEvent from the CGEvent. guard let event = NSEvent(cgEvent: cgEvent) else { return } virtualMachineView.rightMouseDown(with: event)

Apple provided solution to this problme via feedback assistant and it worked like a charm.

D’oh, I meant VZLinuxBootLoader. Sorry about the confusion. I am not using kernel boot image which needs VZLinuxBootLoader. i use VZFIBootloader() for running gui based linux vms like ubuntu and boot from iso and install the linux.

Here is the bug number FB22727902

It is not about knowing linux. It is about booting from iso. When no linux is installed vm boots from iso. It would be nice if There is a possibility of booting from the same ISO even after the installation to the hard disk. Boot priority selection would be a nice addition to the virtulization framework.

Any update on this whether mac os 27 will have this feature?

Thank you for the reference i tired it and it worked like a charm.

Hi, Thank you for the reply. I was able to solve the problem. The problme is not becuase of deduplicated_symbols. I had some data race conditions modifying published vars from different threads rather than on main thread. Now it is fixed.

[quote='884854022, DTS Engineer, /thread/822658?answerId=884854022#884854022'] The bad news is that this is a known limitation of vmnet (FB7731708). [/quote] I think i need to wait for the fix. however i released my app with this limitation. Hoping that it will be fixed soon. How can i track the bug myself. because i cant access the feedback you have mentioned

Here is the FB No. FB22589442

I wasn’t able to find an equivalent bug for DHCP reservations, so I recommend that your file your own about that. I think i wont file the bug since it is not a bug and it is by design it is clearly documented here https://developer.apple.com/documentation/vmnet/vmnet_network_configuration_add_dhcp_reservation(_:_:_:)?language=objc

utm app uses this method https://github.com/utmapp/UTM/blob/30c8202c630c5af2e3c3403df1bb95c962459bc6/Services/UTMASIFImage.m#L18 is it allowed in sandboxed environment?

now it fails in 26.5 beta 2 with operation not permitted error. I am not sure why apple keep introducing new bugs for this feature. we cant rely on this method at all. need a better stable way for creating asif disk programmatically. apple keeps breaking things . what will happen to live applications on appstore. i am very disappointed Update: Downlaoded xcode 26.5 and it seems to be fixed the problem. sorry about the above post
