### Ivy Bridge and Haswell Notes
Currently in Big Sur 11.0.1 and 11.1, there are partial firmware brickings happening during the install stage. The exact issue depends on the CPU model generation:
* **Ivy Bridge**:
* Simply power cycling the machine will resolve this issue
* Laptops will need to unplug the battery for a bit
* To avoid this issue outright, simply shutdown the machine after Big Sur has installed macOS instread of having the installer auto reboot
* **Haswell**:
* Power cycling *may* work however some iMac14,x users have reported needing a firmware reflash
* Patcher currently has removed support for these machines till macOS 11.2's release to avoid any unnessary headaches for users
