Hey guys I just came here to post as I am a bit worried, My MBA (Late 2010) was getting sluggish, tabs were taking longer to open and pages documents longer to save. Then the computer completely went black and unresponsive with 10 mins battery left and when I plugged it in and turned it back on the clock had been reset to 01/01/2001 and it had forgotten my WIFI password. I am now worried about a couple of things. Why did it crash? Did its battery die? Why when it said it still had some charge left? Has the SMC gone wrong or something? Also it was slowing down and getting worse for the past couple of hours, far before the complete crash happened. Any idea what's up or how to resolve it? Also do you know what else I can expect to be missing or which settings might now be screwed other than the clock and wifi password so I can fix them? Many thanks, Joseph Edit: Battery health has now dropped an additional 6% since crash. What's up? More importantly, I just verified my permissions and there are about 30-50 problems and every time I repair it says they're fixed but then I check again and they're all still there. One entry also says: "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired. I'm even more worried now!
