<p>The only info I'd add, is to find out how to prevent your OS from
sleeping an application and also from powering down what it things
are unused USB ports. I'm not a Mac owner/user, but I hear that
"AppNap" causes *A LOT* of issues.</p>
<p>Also, research and find out how the serial ports are identified
on your particular system, and how to search for those that
*Really* exist. Mac OS's are based on BSD, so there might be
some help there. Find out how to get to a command line terminal
display, and learn the basics of how to search for and do stuff
there. Just as the rest of us with other 'Nix related boxes have
learnt.</p>
<p>(ls /dev/ttyUSB* for example will list the real existing ports on
a debian/ubuntu based Linux system.)</p>

</tt><tt>/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3</tt></font><br>
</p>
<p>That is on my Linux Mint box, but Mac's / BSD's etc will almost
certainly have something similar. <tt><font size="+1">"<code><span

As one website I found indicates... Not having a mac here, I cant
test that.<br>
</p>
<p>Also, as Randy said, steer clear of clone chip-sets. ONLY buy
stuff like that from authorised resellers, not eBay. Disclaimer!
I have had good genuine stuff from eBay, but I've also had a lot
of clone rubbish. (I did have one chip that was physically marked
up with the FTDI logo and part number etc, but when connected to a
computer, it announced itself as a Prolific chip! I felt sorry
for the seller, who was non technical, just acting as a re-seller
themselves. We figured out he had over a thousand fake devices.
He was not happy, but apologised gave me a full refund without
asking, and took the devices back. For that alone I gave him
good feedback.)<br>
</p>
<p>Yes, it'll probably cost more from DigiKey or ??? But you'll
know you have the "Genuine" article, and if it proves otherwise,
you can return it. "Silicon Labs" (SiLabs) devices are good
too. Linux recognises them OK, I have no idea regarding Mac
OS's.<br>
</p>
<p>It has to be said though, that a lot of the current clones are
actually quite functional, unless you want to do something
special, like re-assign the I/O pins, as you are supposed to be
able to do with FTDI parts. (A useful feature, for radio
programming leads.)</p>
<p>Lastly, don't trust pre-made leads from eBay. Again, I'm sure
there are good ones, but again I've also found via others
experiences, that there is a lot of stuff there is wired wrong,
& very wrong at times! (Mind you, some of the radio manuals
are very misleading in this respect too.)<br>
</p>
<p>Best if possible to build your own programming cables. It's not
difficult at all, it just takes a little time to learn about it,
and build and test etc. But, in the long term, you can then
build/adapt a cable "on the fly" when needed.</p>

Hi Tip
First off, don't let your PC buddy's steer you off track. Using a Mac is not an issue. I have 2 iMacs and 1 Mac book, one of the iMacs and the Mac Book is 11 years old and still going strong. I use Chirp on them all the time.
Make sure the USB to serial adapter has a legitimate chip set in it and not some Chinese rip off. Personally I use adapters with the FTDI chip set in them, but Prolific chip set are equally as good.
The only issue I can see you "might" have is the fact that you up-graded to High Sierra, but I'm not sure about that. I have held off up-grading my newer iMac so far.
Check the web site of the 2 chip set manufacturers I mentioned above, to see if their drivers are compatible with High Sierra.
Hope this helps
73 Randy VE3JPU
