![]() Termination Reason: Namespace LIBSYSTEM, Code 2 Application Triggered Fault You can find the details below.Īnonymous UUID: 8BD1AA41-B687-73EB-AD85-5F89ED23CE95 However, when checking for logs, we found that bluetoothd was constantly crashing. In this case, the firmware was also failing to load. The WiFi operation was normal and the USB mapping was implemented. In this case, the Bluetooth does have the address and the State On but fails to initialize firmware. In this case, the Bluetooth does not have its address (NULL) and the State was Off. Upon our investigation, we noticed three scenarios which are described below. We used a few different builds with different specifications. However, a few Broadcom Cards such as Fenvi T919 are an exception and regardless of the macOS version, the BT works with zero issues. The issue exists on natively supported cards (Broadcom, including AirPort Cards) and also community supported cards such as Intel. Apple has changed parts of the Bluetooth stack from kernel space to user space and due to this, the issue exists. Since macOS Monterey, Apple has changed a lot in terms of the implementation of various peripherals, including Bluetooth. When doing a firm investigation, we came to know that Big Sur's Bluetooth implementation is different than Monterey and above, and therefore on a newer macOS version, it fails to find firmware for the chipset and due to this BT firmware isn't loaded at startup and therefore does not work. Upon doing some quick research over the internet, we came to know that many users are having such issues and mostly with Broadcom where the BT isn't working, but the WiFi is. Now, it was time to investigate the OS part, under macOS. Considering the card firmware was corrupt, we tried to update the firmware but found that the firmware is loading and is working up to the mark. However, one unusual thing we noticed was under Windows, the WiFi was available, but no Bluetooth. ![]() We went further and found that M.2 WiFi Slot and the BIOS were perfect. From this, we concluded that there is no issue with the card but could be the M.2 WiFi Slot or the BIOS. ![]() Luckily, we had the exact same build, but a different one with macOS Big Sur, so we swapped the cards, and still a no-go. As a part of the diagnosis, we changed the card with a new one we had lying and it made no difference. We were using Broadcom BCM94360NG from Fenvi on this build. This simply meant that the Bluetooth is either not connected properly or the system is unable to communicate. This means no On/Off function, the BT address was NULL and the State was Off. Interestingly, after upgrading to macOS Monterey, we found that BT was available in System Preferences but it was not working. Recently, we upgraded a build to macOS Monterey 12.6, which was previously deployed with macOS Big Sur 11.6.5. By following this guide, you'll be able to enable Bluetooth on macOS Monterey and Later using Clover or OpenCore Bootloader.
