macOS 26 installation freezes on Intel-based MacBook Pro

Tried last night to install Tahoe on the Intel Based 16" MacBook Pro and by the looks of it device is bricked.


Installation just freezes. After I can see the message stating something like "19 minutes left" laptop reboots few times and during one of the reboots it produces the sound similar to one that it makes when laptop gets connected to the power supply and that's the end of it. Fans are running like mad, laptop does not respond to keyboard or touchpad. Screen eventually gets dark.


I tried to restart it and it boots but when I log in it does exactly the same thing during login, i.e. that sound and gets non-responsive.


Tried to all kinds of woodoo, such as resetting SMC and NVRAM without luck.


Also, tried to load it in the safe mode but it still fails to load but instead of freezing with the beep laptop screen gets black.


Tried to apply first aid to the disk and tried re-installation few times but getting the same result.


Any ideas if it is possible to get out of this mess?
