frequent crashing - macbook air w/ Yosemite
Hi,
I have a macbook air, mid 2012 with yosemite (10.10.4). It starting crashing frequently recently. Sometimes with the power cord plugged in and battery fully charged, sometimes without plug. Sometimes it happens when I unplug the computer, other times, I'll be typing and it will just happen.
I upgraded to Yosemite a few weeks ago but this problem only started this week. I swapped out my battery a couple months ago. Fan sometimes is running but it's not feeling too hot (at least not now, when it just happened).
Any ideas how I can troubleshoot?
Thanks!
MacBook Air, OS X Yosemite (10.10.4)
