I agree with the Top Sites need to give you the option to not use Top Sites. For one, Google Chrome is a garbage browser for Macs. I don't know why anyone likes it, because it's buggy as hell compared to Safari. I've tried other Browsers but I get graphics errors such as not being able to scroll in certain Flash based Chatrooms unless I use Safari. Xat Chats does not work right for me on Google Chrome and works perfect on Safari. Mac OSX is built for Safari Browser, so I don't understand why anyone would use any of the other glitchy browsers.
Also, the reason I want to get rid of Top Sites, is because I browse porn and if I want someone to try out my Mac computer, I want them to be able to not see my TopSites at big dings bang tight holes and you get the point not to get too graphic.
I'm running Mac OS Mavericks on Macbook 13" May 09 model, and also they need to do away with that ugly wave background. I know you can change the wallpaper, I'm not an idiot, but I do think that is one of the ugliest Wallpapers I've ever seen Apple use. Couldn't they have chosen a much prettier Wave instead of that fugly color?
Wi-fi drops connectivity now. Ugh.
Try changing the channel on your Wi-fi router settings, that helped fix the problem for me in Mavericks preview 1. But I don't even think that was a Mavericks issue, since my brothers computer was messing up to with the Wireless. You might be running into something different. Post your specs and maybe someone can help you out, and also it might help to post it on the official Apple Website.
My update is stuck at the "Completing Installation" screen with "Less than a minute remaining". Been stuck here for close to 15 minutes.
That has happened with almost every Mac update I've had. It sometimes will count negatives, but all in all it finds out whatever is going on and it finally installs. I'm on a older Mac tho, which I don't know if that is the cause of the problem or if its gpu or something related.
