Are you getting Kernel Panics in 10.10.3?
I had a kernel Panic this morning while I was using Mac 10.10.3. It has been years since I had a kernel panic. I was using the newest Firefox and looking at my webhost interface and it crashed. I have since gone back and tried to replicate the crash and it didn’t happen a second time.
Kernel Extensions in backtrace:
BSD process name corresponding to current thread: distnoted
A google search for distnoted shows that this is a notification service that people had problems with back in 2011. Apparently it also caused kernel panics for them. One person said that kernel panics generally show a hardware problem which is reasonable since my laptop is older. Another person pointed out this is due to software issues that cause the computer to lose ram while it is operating.
At this point it seems more likely to be a hardware issue to me. I will make an appointment with a genius and report back my findings.
In my mac history I can only count on one hand the number of kernel panics I have seen. Blue screen of death is unfortunately common on a Windows machine. Most kernel panics have been due to bad ram or failing hard drive or logic board. There was a period of time where kernel panics were caused by software, but that was years ago during the painful change pre 10.8. Since 10.8 the Mac OS has been remarkably stable as a whole. Of course there are always issues, but you rarely see this behavior.
