This is annoying. Decided to get on the PB track so started with PB1 and had worked my way up to 3 with no issues. I went to install PB4 and I'm getting a kernel panic at boot. I can see the issue is with an old kext I didn't even know I still had loaded but I'm stuck in trying to fix it. Single user mode also panics so I'm only left with Recovery mode available. I deleted the offending kexts from System/Library/Extensions and deleted the kext cache in /System/Library/Caches but I'm still getting the panic. Any ideas?
