Memory and Freezing Questions

Hello all. Sorry, some of this is a repost, but I have questions about a 2010 macbook pro that are way above my pay grade:

I have recently been getting an alert, probably once a week, while using safari, stating that I have run out of application memory and that I need to force quit open programs. Usually the only programs I have open are finder and safari. Then, when I close safari and check my activity monitor, the free memory is usually 1.7GB. When I open safari, the free memory may decrease to 1.4GB, but there's still a good portion of it left.

However, when I reopen safari, my homepage is reset to the apple page, and my extensions are reset and tabs open for their configurations. My history is also erased, but everything else appears normal. My bookmarks and topsites are untouched. I'm currently using Safari 5.1.9 on Mac OS X 10.6.8. My extensions are AdBlock, Ghostery, and DoNotTrackMe. I recently disabled DoNotTrackMe, just to see if that helped, and I haven't had the notice about application memory since, but just tried restarting my computer, due to safari not loading facebook, but loading every other page, and received a message saying that I needed to restart my computer by holding down the power button. When I restarted it, I received the following error:

.......and this is why ive been telling everyone to buy anything BUT a MacBook Pro RETINA

too many bugs and design flaws.
Well it's a 13" macbook pro from 2010. Not sure if it has the retina display or not. Do you know if there's anything detrimental going on with it? This is the first time I can remember it having problems like this.

Did you actually READ the initial post? Or did you mis-speak and mean to say that you've been telling everyone NOT to buy anything but a Retina?

In either case, your post is less than helpful. :rolleyes:

OP, how much free space does your HDD have currently?

strange you have lots of hard drive space and get this same issue. I have just 12 gb left on my main boot partition, mostly happens if i do not restart the mac. I wonder why from 12gb the free space starts going down to 100mb without downloading anything just net surfing some youtube. A restart helps fix it. I only restart or shutdown when the free space gets super low:D

in total i have just 50 gb free of my 750gb hdd:cool:

New Development

So, new development. The alert that I needed to restart the computer manually came up again, but this time when I restarted, I was stuck on the gray screen with the apple logo, and the computer wouldn't progress to log in to the desktop. I had to restart two more times in order to get access to the desktop. I was not given an error message when I was finally able to use the computer. Anyone had this happen before?
