How To identify and disable system extensions that cause other apps to crash
Authored by: vykor on Feb 27, '12 02:28:01PM

To add to this, a fair number of kernel panics (the "you have to restart" kind of full system crashes) are due to incompatible kernel extensions, or kexts, located in /Library/Extensions and /System/Library/Extensions. Most of the time, repeated kernel panics due to kexts start to happen after an OS update or an app update, but sometimes there are just bugs in the kernel extensions that don't surface until a specific usage scenario occurs. The offending extension usually show up in the panic log.

In general, I'm extremely wary of any application that installs kernel extensions, just because these things will take down the entire system if there is a bug or two. Sometimes they're unavoidable though, usually because they are device drivers for some hardware. But a very rough rule of thumb is: the fewer third-party kernel extensions you have to keep around, the more stable a given system tends to be.

How To identify and disable system extensions that cause other apps to crash
Authored by: pentique on Dec 09, '12 11:25:43AM

Could one super simple resolution to the kext problem just remove the offending extension? No crashes just a constant popup window informing me, after months of a trouble-free mac mini and printer symbiosis, that one of my printer extensions was installed improperly. Apologies in advance for not including the message as written. I updated my printer since the upgrade was a software update but the problem continues. Any suggestions?

Thank you.
