How is it possible to bring up the new startup options on a mac mini or mac pro that is in a distant, locked and cooled data center/IT room, and I only have remote KVM access to it but I am not there physically to press and hold the power button? I want to be able to select which device to boot from when I reboot the machine on the fly from a keyboard or some other way remotely (like MDM? iLO?), so I can select which boot device to boot from. Is it expected to stand next to the mac with this change for bringing up startup options? I am really hoping I can still use keyboard or ability to send a command to select boot device remotely.

Hello, In the Explore the new system architecture of Apple Silicon Macs session, in the recommended sessions to watch, you have WWDC14's Direct Access to Video Encoding and Decoding, but I could not find it anywhere on Apple's website. If you google for it, you can find a direct link to the slides on the CDN, and an unofficial transcript, but no video. There's very little information available about VideoToolbox so if you could bring back that video it would be very useful. Thanks

Intel Macs used GPT for partitioning storage devices. What partitioning scheme are Apple Silicon computers using? Or are they still going to use GPT/

On Intel Macs, it has always been possible to boot other operating systems, including Windows with Bootcamp and Linux. Assuming a proper ARM port of Linux to Apple A-Series SOCs is made, will it be possible to boot Linux directly on the new Apple Silicon Macs?

Internet recovery was referenced as an “Intel based processors recovery mode”. Will It be still available on Apple Silicon?

In the session it is said that Apple Silicon has a unified login experience with and without FileVault, made possible by fully booting macOS without requiring the user to unlock the system. Does it mean that at login screen after restart the system will connect the Bluetooth Low Energy mice and keyboards? (Currently FileVault On prevents BLE mice and keyboards to be connected before the user logs in after a restart.)

The video for this session mentioned that csrutil is able to control settings related to Secure Boot on Apple Silicon Macs. Will csrutil on Apple Silicon Macs allow for Secure Boot to be disabled, opening the ability to boot arbitrary unsigned operating systems?

Where can I find more information about Mac Sharing Mode?

On the ARM architecture Wikipedia page - https://en.wikipedia.org/wiki/ARM_architecture#Cores it is stated that Apple's M1 chip is on ARM version 8.6, so I was wondering if it is fully supporting all the ARM version 8.5 features, such as the ARMv8.5 Memory Tagging Extensions (MTE)? If so, would it, like pointer authentication, require any special configuration to enable this feature, or is it supposed to work out of the box?

In the session it was mentioned that the new unified login has an accelerated UI because the OS is fully loaded even if FileVault is enabled. Does this mean that the WindowServer process is also running and 3rd-party code like pre-login agents (launchd agents) can run at that stage (with the disk still encrypted)?

In new Apple Silicon macs can i install the Linux OS in separate partition , is there any change in that procedure as compared to intel-based mac ?
