# Current Monterey Issues
# MacBookPro11,3 booting issue without Kepler acceleration
Due to the display being routed through the NVIDIA Kepler card and macOS being rendered on the Intel iGPU, users have been experiencing issues booting without post-install patches applied (see here for more info (opens new window).) Currently the only workaround is to install the patches in safe mode, by holding down Shift+Enter
when you select macOS in the OCLP boot picker.
# Previously Broken Hardware

- Associated Github Issue:
macOS 12.0 Beta 4 issue on 2012 to early 2013 machines (Resolved in 0.2.5 and newer)
Currently in macOS 12.0 Beta 4, many Ivy Bridge Macs have experienced Bluetooth issues relating to their BCM20702 chipset. Currently the exact issue is unknown however is assumed to be a bug on Apple's end. Recommend downgrading to macOS 12.0 Beta 3 till resolved:
