If if ain’t broken, don’t fix it. I’m going to have that tattooed on my body somewhere. There are countless examples of how screwing around with properly functioning devices on boats can cause problems but I think the best illustration is with computers. I learned a long time ago not to update software or operating systems unless I have a really good reason for doing so. Sometimes, however, you just don’t have a choice.

Sadly, this blog post is being typed on my old on-its-last-legs laptop instead of our new MacBook Pro because the new one came installed with an updated operating system which is not compatible with our Alfa Wi-Fi amplifier (AWUS036H). What to do? What to do?

Answer to yesterday’s questions:

SART: Search and Rescue Transponder. This is a device operating on radar frequencies that is designed to produce a distinctive pattern on an approaching vessel’s radar. A SART transmits a series of 12 pulses at very short intervals which, on a radar screen, will appear as 12 small contacts starting at the position of the SART and stretching outwards towards the edge of the screen, 0.6 miles apart.

Today’s question: What is Buys Ballot’s Law?


  1. Ah yes, Buys Ballot… I like this one… When standing facing the wind, the center of high pressure will be to the left and slightly forward and the center of low pressure will be to the right and slightly behind. This will be the opposite in the southern hemisphere.

  2. Ouch…that looks nasty! What did you do to that! Blow torch it?

    Mike, Why not install the old OS compatible with your wifi amp (assuming its using Snow Leopard) on an external firewire harddrive and you can boot from there as a ‘work around’. I can bring snow leopard install with me on a spare disk if you dont have it.

    I work on macs a lot……



  3. Yeah, unfortunately it says on Amazon, “For MAC OS 10.6.7 and later version, we suggest AWUS036NHR, AWUS036NH, AWUS036NEH, AWUS051NH.” Bummer.

  4. Create a virtual machine that uses the old OS on the new Mac, then install and run the software on the VM? Or just get a new Wi-Fi amplifier 🙂

  5. Yes, like D says, you could also set up a virtual machine and install the old OS in that.

    Something like parallels or vmware fusion.

    This way might be cheapest way depending on your access to resources….. No need for a external drive….but does need plenty of RAM to run sweet….like about 4GB.

  6. There aren’t updated drivers for the Wi-Fi amplifier? Does it even use drivers?

    I don’t know what I am talking about so I am just going to slink off now.

  7. Mike, I’m making you an honorary Texan for this display of marksmanship. My only advice is, next time, use a larger caliber gun!

    That comp looks like it was shot !!! i have learned also not to do up dates as a $700 ipod stuffed up after updates & apple wont admit they had issues but there are forums saying people had the same issue Mike Good luck with the new ipad

  9. Isn’t that how politics is handled…? the Law of Buying Ballots?!?!
