I'm guessing it's a hardware problem, because I keep hearing about people keeping 50+ tabs open on their Windows computers, but it seems like 10 is enough to crash Safari. When I open it again, it loads right away and loads up the tabs up to the lat 30 seconds or so before the crash, as well as logging me out and erasing all fields. I've since adjusted my browsing habits by keeping a folder on the desktop full of TextEdit files, so when I am in the middle of filling a long field, I can periodically copy and paste it into the TextEdit file. Then, when Safari crashes I don't lose what I was writing. I also started using 1Password as a fix for being signed out of all my tabs, so then all login fields are filled instantly. But people that see me work have started commenting and FaceBook friends are all thinking that I have a spotty internet connection. The machine is in perfect working order otherwise, except for a few issues with some apps that refuse to open unless I restart the machine. And also the trackpad. It keeps jumping around erratically, and for some reason when I look in a list of files in Finder, it keeps jumping to the top, so my fix for that has been to keep jolting my fingers up and down while browsing a list, to stop it from bouncing up by itself. Also when just typing, the mouse will move by itself, I suspect palm rejection isn't working. Other odd mouse behaviour too. I don't really know what to do about it. I've bad a string of bad luck with Apple products, I had a screen defect on my Air, camera defect on my iPad 2, my magic magnet cover for iPad 3 had some weird defect where it scratched off some of the coating on the iPad, I had a MacBook with a cracked keyboard case because of a defect in the design. But because there is no Apple Store in my city, and none of the authorised repair guys even want to know you, I never got them fixed and the included warranty period on all of them expired before I got around to figuring out how to claim on them. Now there is an Apple Store coming to my city in a few weeks, so is this something I need to bring it in for? Are these common problems for the rMBP, or is it just me? I feel conflicted because this computer is absolutely beautiful, even if the GPU is underpowered considering the screen resolution, it's still easily the computer I have ever owned. There is no going back to anything less beautiful than this now. It's just far less functional than my old Air or MacBook was, with the crashing and trackpad problems. Even my old PPC Macs were more stable. I'm not a rich person at all, so I get kind of cheesed off when there's problems with all the Apple stuff I buy, but I just keep buying it.
