Below excerpt is from the interview of the Man who broke  into MacBook within 2 minutes in Pwn2Own contest. 

Alan: How much of your work today is focused on securing Macs vs. PC vs. Linux? Who is your typical customer?

Charlie: At work, I mostly look at application-level security. Most of this is really independent of operating system. For example, source code reviews or reverse engineering binaries doesn’t depend much on the operating system. I’ve spent a lot of my research time on Macs because I like them and they also happen to be pretty easy to break!

Most of ISE’s customers are small to medium size companies that care a lot about security and want to make sure their applications are secure.  The companies that only want a check box usually go somewhere else because we are pretty good at what we do and consequently charge more than many other consulting firms.

I generally get crash messages in Apple Mac built in applications despite being such a so called great OS lol . And what i send as a message to Apple is below . May be you should also try similar..

Computer scientist Brian Mastenbrook has discovered a fairly serious bug in Safari’s RSS feed handling that can allow a maliciously-crafted web page to access personal information without any knowledge or intervention of the user. The information can include—but isn’t necessarily limited to—e-mails, passwords, and information stored in browser cookies.

This vulnerability affects any Mac OS X user that has Safari set as the default feed reader in Safari’s RSS preferences. You can be affected by it even if you don’t read RSS feeds or regularly use another browser such as Firefox. As for Windows users, the vulnerability only affects those who use Safari to browse the web.

Solution/Workaround for this problem is very simple.

Relatively popular Mobile community site Sms.ac doesn’t support Safari . May be its because its in Beta but they must have considered Safari browser at least in Beta phase. Proof below. This is Windows and IE World

I primarily use Firefox at my Windows machine but in Mac i use Safari ( why? ) . But there are multiple things i dont like about Safari than Firefox. One of them is how Safari shows popup confirmations to remember passwords . Safari doesn’t let you go past the password page till you decide yes , not now or never in its confirmation popup. I dislike this. I love the way Firefox handles this. In older version of Firefox such popup were there but in latest ones its removed with a pretty good banner at top which appears till some time after you passed the password page. Safari behavior is specially annoying when you ask Safari to remember the password and it happens to be the wrong password. ( so may things so many passwords you know ). The way Google Chrome handles is the advanced one among all the browsers i have seen. Its very intelligent. 

Safari and Internet Explorer match in this case because latest version of both Browsers use similar popups where your input is a must to go to the next page.. Safari and IE friends . Seems unconvincing huh..
