What Happens If You Don’t Block Updates on T2 iBridgeOS?
When you update your MacBook T2 to macOS Sequoia 15.2, the update automatically disables the iCloud bypass functionality in iBridgeOS 9.2. As a result, all bypass tools will stop working, and the iCloud lock will remain active on your device. Blocking updates is crucial if you want to continue using the iCloud bypass.
To ensure your device remains secure while maintaining the functionality of iBridgeOS, here are a few proven methods to block macOS updates on your T2 device.

sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CriticalUpdateInstall -bool falseThis method will block updates on your MacBook T2 running iBridgeOS, offering you greater control over system updates.
Method 3: Block Updates Using Third-Party Tools (AldazOTA or CodeBreakerT2_OTA)
If you prefer a more user-friendly method, third-party tools like AldazOTA or CodeBreakerT2_OTA can simplify the process of blocking updates with just a few commands.
Steps to Use Third-Party Tools:
