More about the Shellshock bug
Oct 1st, 2014 by jyamada

First off, the bad news: Mac OS X 10.6 and earlier operating systems are no longer supported and will not receive a fix from Apple.

The good news is that Apple has released official patches for [10.7 Lion](http://support.apple.com/kb/DL1767), [10.8 Mountain Lion](http://support.apple.com/kb/DL1768), and [10.9 Mavericks](http://support.apple.com/kb/DL1769). And an enterprising group of open source folks have released instructions for patching older systems like [10.4 Tiger on PowerPC and 10.6 Snow Leopard on Intel](http://tenfourfox.blogspot.com/2014/09/bashing-bash-one-more-time-updated.html).

The even better news is that you were probably not vulnerable in the first place.

Here’s more detail. A bug was discovered wherein the bash command line environment that is used in Mac OS X and other UNIX like operating systems could be tricked into running a line of maliciously crafted code. In general, an attacker would need to have physical access to your Mac in order to run the Terminal program.

There was a distinct danger for those people running servers connected to the internet because servers would open up the command line to provide extra services to internet users. These services are not turned on by default in Mac OS X. A user would have to have turned on Remote Management in the Sharing menu of their system preferences in order to have exposed themselves to the internet at large.

In summary: You were probably not at risk from this bug, and now there is a patch to fix the bug.

How bad are counterfeit chargers?
May 22nd, 2014 by jyamada
A photograph of two very similar looking chargers, with one being a genuine Apple charger and one being counterfeit.

Can you spot the differences between these two chargers? The genuine Apple charger is on the left, while the counterfeit on the right states that it was ‘Designed by California’

It’s pretty widely known that you can buy cheap counterfeit chargers for your iPhone and iPad on places like eBay and Amazon. Anyone buying such an ‘unbelievably good deal’ probably knows that they are taking a risk, but up until now it has been hard to say just how much of a risk one was taking.

Blogger Ken Shirrif goes in great technical detail to illustrate the differences between 12 different chargers from cheap counterfeits up to name brands like Apple, Samsung, and Motorola. Also compared are high quality 3rd parties like Monoprice.

Ken Shirrif’s blog about chargers

The lowdown: Avoid cheap counterfeits as they can be wildly dangerous. This issue came to prominence when a woman in China was killed by electrocution while talking on her phone that was plugged in and charging on an alleged counterfeit adapter.

Update your Mac OS X for malware removal
May 14th, 2012 by sriggins

Now that Apple has released an update to OS X Leopard (10.5) for the Flashback Malware, I highly suggest that you update your 10.5, 10.6, or 10.7 to the latest versions.

This malware is not terrible, but it is best to have it removed from your system if you have it.

Lion Tips

Here are a few tips for your brand new OS

 

 

Getting ready for Lion
Jul 19th, 2011 by sriggins

Mac OS X Lion (10.7) is going to be released soon.  Are you ready?  If not, I suggest you wait for 10.7.1 to be released.  Let others find the bugs and issues.  In the meantime, make a list of your printers and other peripherals, then research their Lion compatibility before upgrading.

Another great resource to help prepare you for Lion is Macworld’s Article on Getting Ready for Lion.  Be sure to check it out before considering upgrading to Lion.

Whatever you do, create a full clone backup of your hard drive before installing Lion.  This will allow you to revert to a known working system should something go awry.

Apple has posted a Mac Defender security patch
May 31st, 2011 by sriggins

Check software update and install it now.  This update will remove Mac Defender and keep it from being installed on your system.

Apple posts Mac Defender support document
May 28th, 2011 by sriggins

In case you have missed it, there is some malware for the Mac running around called Mac Defender.

If you use Safari, please go to your Safari preferences, General section, and uncheck “open safe files.”

If you think you have the Mac Defender malware on your Mac, or are curious about what it is, please see this document:

Thanks to Rory Bowman at AppleVan for alerting the group to this weeks ago.
