MacBook won‘t turn on after Monterey install

MacBook pro 2019 after monterey update the computer won’t turn on at all.


tried the usual suspects (pram, pressing command-option-r etc.) but nothing. Computer is also perfectly powered but nothing, no chime, no harddrive sound just a dead computer after the monterey update.


seems like a computer without power but it is fully powered



MacBook Pro 15″, macOS 10.13

Problem: you need a second computer with the same or an higher operating system version.


As I didn’t have a second machine with Monterey already running, I went to the Apple Store and they revived the T2 chip. Problem solved and I hope this will also help others who faced bricked computers after the Monterey install.

Hi,


I also have this problem after clicking update on my MacBook Air (13-inch, Early 2014). The machine is bricked and won't boot.


I have an intel Mac Mini that has been updated successfully to Monterey (phew!).


My question is now: Can I use the following cable to connect my two Macs in order to use Apple Connector 2 to revive the firmware on my MacBook Air: https://www.apple.com/shop/product/HN892ZM/A/mophie-usb-a-cable-with-usb-c-connector-1-m


Thanks :-)

We're discussing this on apple's official platform and so far no official statement from Apple. (The one which Rene shared is unofficial according to apple support since it didn't come directly from Apple.)


I don't think apple given its reputation of being the torch bearer for new consumer tech. and charging a premium price for its product should treat their customers like this. It's a simple fact that thier update has bricked our laptops and they're liable to fix it.

I have MacBook Pro 2019 13 inch. After Monterey it started to reboot automatically every 137 sec (literally second to second) otherwise everything works fine. I removed the monterey and it bricked. After restoring T2 it still reboots every 137 sec and doesn’t let me to finish installation of MacOS. No Apple Genius Bar around, only authorized service providers that ask me to pay money for even taking a look at my Mac. I ain’t gonna pay a single penny.
