Free app checks for the Flashback trojan infecting 600,000 Macs

Copied from 9to5 Mac…

Over the past few weeks, security experts have warned Mac users of a new virus making its rounds called the “Flashback” trojan. Flashback is allegedly on over 600,000 Macs, which is roughly 1-percent of the 45 million out there. Flashback exploits a pair of vulnerabilities in older versions of Java. Apple may have patched it, but it is still out there and running on many machines.

How do you know if you are infected? F-Secure has a few Terminal commands to check your machine. For the many who are not adept at keeping their Java updates fresh, terminal commands are going to be even more foreign. Luckily, ArsTechnica points us to a free Flashback checker available on github. The app runs the same checks as you would in Terminal, but automates it for you.

We ran the test ourselves and were clean, but one of our readers found that he had the virus last week. It is definitely worth checking out. If your Mac does have Flashback, F-secure offers a great guide on how to remove it.

This is a great tip to improve photos on your iPhone. I have been trying to get better composition of photos with the iphone (even for everyday shots) and I tended to get an approximation of what they’re talking about here. But this really crystalizes the concept to the iPhone form factor. Saves alot of practice shots!

(Photography geeks – feel free to pity my weak photog skills…I’m comfortable with that…)

Home office must have: HP LaserJet Pro P1606dn Printer

Media_httpimagesamazo_ggpaa

This printer is flat out awesome. Bought it as an upgrade. Google Cloudprint compatible. Airprint compatible (a top reason for getting it in my home office). Super fast. Huge paper capacity. Duplex printing out-of-the-box.

I actually got it on a Black Friday special for $99 – ridiculously good at that price. Some vitals on it:

Print Speed: Black (normal, letter): Up to 26 ppm; Black (normal, A4): Up to

25 ppm

Print Resolution: Up to 600 x 600 dpi

Standard Connectivity: Hi-Speed USB 2.0 port, 10/100 Ethernet networking

Monthly Volume (Duty Cycle): Up to 8,000 pages

Duplex Print Options: Automatic (standard)

I connected it to the Ethernet port of an Airport Express and Voila! It appeared as a service to all my Macs. This printer rocks. Highly recommend if you need a good B/W laser for the home office (and I’ve had a couple for the last decade).

Useful Mac for Business tip: Using a 27-inch iMac (Late 2009 or Mid 2010) as an external display

To use an iMac (27-inch, Mid 2010) or iMac (27-inch, Late 2009) in Target Display mode with another computer as the source:

  1. Make sure both computers are turned on and awake.  
  2. Connect a male-to-male Mini DisplayPort cable to the Mini DisplayPort on each computer. The 27-inch iMac will enter Target Display mode and display content from the source computer.
    Note: If you are connecting two 27-inch iMacs, connect a Mini DisplayPort cable to each computer and press Command F2 on the 27-inch iMac keyboard that you will use as an external display. 
  3. To leave Target Display mode, press Command F2 on the keyboard of the 27-inch iMac that is in Target Display mode. To return to Target Display mode, press Command F2 again.

Points to keep in mind:

  • Applications running on the 27-inch iMac computer remain open and running while it is in Target Display mode.
  • Use the keyboard of the 27-inch iMac to adjust display brightness and sound volume and to control media playback of applications running on the 27-inch iMac in Target Display mode. Other keyboard and mouse input is disabled on the 27-inch iMac while it is in Target Display mode.
  • The 27-inch iMac works like any other external display while it is in Target Display mode, except that you cannot access its built-in iSight or USB and FireWire ports. To change display settings, open System Preferences on the external source computer and choose Display from the View menu.
  • Mac OS X on the 27-inch iMac ignores some sleep requests while it is in Target Display mode, but forced sleep, restart, and shutdown commands will still work. If the external source goes into idle display sleep, the 27-inch iMac in Target Display mode will go dark until activity resumes on the external source.
  • If you shut down, sleep, or detach the external source while In Target Display mode, the 27-inch iMac will leave Target Display mode.
  • The Mini DisplayPort in the 27-inch iMac can receive only DisplayPort compliant video and audio signals. Converters not made by Apple may provide options to convert other electrical, video, and audio protocols to Mini DisplayPort compliant signals.
  • Some older Apple keyboards and keyboards not made by Apple may not allow the Command F2 key combination to toggle display modes. You should use an aluminum wired or wireless Apple keyboard to toggle Target Display mode on and off.

Especially useful if you have to review documents and papers in your home office.
