Since the 10.8.3 update, my late 2011 hires antiglare 15" Macbook Pro fans have been running constantly. Now I've gotten somewhat used to this since Apple started this Java war with 10.8.1 disabling Java. My fans go like crazy randomly as Java loses its marbles and my Crashplan backup stops working. This was different. This time the fans come on 2 minutes after boot and stay on. In the console, I saw 4,000 entries an hour. Almost all of them had something to do with ReportCrash. In Activity Monitor, ReportCrash had 96 to 600% cpu. I decided to search google and MR to find a solution. I tried deleting caches, checking disk permissions, all to no avail. With Apple support on the phone, I reset SMC, cleared PRAM and verified Macintosh HD. All to no avail. The system was running so poorly, I couldn't even launch the remote support app. Finally we decided to do internet recovery. What a joke. It said it would finish in 12 hours. I don't have that kind of time. I whipped out a usb stick with 10.8 on it and booted from that and I gave the Apple support agent (and www.apple.com/feedback) a huge earful about internet recovery that takes 12 hours. OSX is now officially worse than windows in the recovery department. I remember wasting 90 minutes dealing with Windows but never 12 hours waiting for an over the internet install. BTW, this isn't only Apple's fault. It's Comcast too. Testmy.net says I get 24 MB down but Comcast does all kind of throttling and other silliness that left me with a 12 hour estimate for completion of recovery. Shame on Apple for putting my Mac recovery at the mercy of clueless idiots like Comcast. Anyway now that I'm back to 10.8, my fans are off and Crashplan is working again. I have to file my taxes in a few days so I don't plan to tinker with this crap any more until after April 15th. Until then (and possibly a LOT longer, I'm a 10.8 user).
