When your computer is running a little bit slowly, how can you tell if getting more memory will help you? Here is a simple way to check whether all the RAM you have in your mac is being used. It works for any macintosh running OS X – G4, G5 or intel macs.

F-Secure has apologised about a bug in its consumer-focused Mac security software that left surfers fighting against their own browsers as clean files were wrongly classified as malign.

A team of security researchers from the French pen-testing firm VUPEN successfully exploited a zero-day flaw in Apple’s Safari browser to win this year’s Pwn2Own hacker challenge.

For as much as Mac OS X has a reputation for being safer than Windows, security researchers won’t hesitate to point out that the opposite is, in fact, true. Indeed, the primary reason why the Mac has been relatively immune from security threats often found on Windows is because the Mac’s relatively paltry market share makes it an unattractive target for malicious hackers.

As my colleague Rich Baldry pointed out earlier, Apple officially launched the Mac App Store today with their release of OS X 10.6.6. The App Store provides undeniable benefits to users who wish to easily find new programs and reduce the number of companies they share their credit card details with.

"Apple this morning announced that the Mac App Store is now open for business, as previously announced, with more than 1,000 free and paid apps."

"It’s a very Merry Christmas for Mac developers. Rasmus Andersson has open sourced Kod, the “programmers’ editor for OS X.”"

"Last week I presented my research about “Adding ASLR to jailbroken iPhones” at the Power of Community 2010 (POC2010) security conference in Seoul. During my talk I explained how one can use a modified ‘rebase’ utility to rebase the dynamic linker dyld on the iPhone. Rebasing dyld is important because it contains enough code gadgets that can be used to kickstart arbitrary shellcode on jailbroken iPhones. A tool called Antid0te will be released until the end of this year that allows normal users to add ASLR to their iPhones."
