update 10.13.2 turned my Macbook Air 2012 11" into brick

Hi there,

I had exactly the same issue, but found a way around it, subscribe to Apple Beta Program, download and install macOS High Sierra update 10.13.3 beta, here is how:

Subscribe to Apple Beta:

Apple Beta Software Program

AppleConnect Sign In

enroll your Mac

Download Feedback Assistant:

Do a full backup with Time Machine:

How to use Time Machine to back up or restore your Mac - Apple Support

Once done then go to App Store and update the above mentioned update!

Let me know if it was helpful and more importantly, in a later stage if you have resolved this issue, as it seems that there are a high volume of issue with the 10.13.2 update, and it would be important to inform other users of a way to resolve it!

Good luck!

Consider not to install it on old Macbooks

Too late, I already installed it and it's running fine on all my MacBooks, including models older than yours.

What is your definition of a brick? Does your computer do anything? Was your computer running alright prior to the update or were you trying to fix an issue by updating? Installing the update does not turn a computer into a brick, something went wrong with the update or something else on your computer. Can the computer boot? Can it boot in safe mode?

I recommend not installing a beta version of the operating system until you first determine what is wrong with your computer.
