i have been using Beta software for a while now, but it is the first time I have encounter such problem. The mac i am currently using MacBook Pro early 2020 (intel, 4 thunderbolt ports). this mac comes with a T2 Chip which runs BridgeOS. I have recently received notification form the settings app saying a new macOS version (Sonoma Developer Beta 4) is available. After attempting to update the software, it seems to corrupt the 2 copies of BridgeOS on the T2 Chip and the device will crash when it is connected to a charger under, safe mode, normal mode and recovery mode. I would like to know is anyone else experiencing this and have anyone found a work around yet. At the meantime, i will try to put the T2 chip into DFU mode and restore the image on the chip. Any help would be appreciated! Best Regards, Peter
