Selecting a hidden file from the MacOS File Chooser dialog

I’ve wondered a couple of times how you can navigate to a hidden folder and/or select a hidden file when an app requires you to pick a file using MacOS’s file chooser, because by default neither are visible in the chooser.

A quick search found this post and the easy but not so obvious answer is to use either:

Shift + Command + . to show/hide hidden files/folders
Shift + Command + G to get the ‘Go to Folder’ dialog where you can type in the folder name if you already know where you’re trying to browse

Burning ISOs to disk on MacOS El Cap and later

Prior to El Cap, the Disk Utility on MacOS had an icon to burn an ISO to disk when you mounted the iso. For whatever reason this was removed in El Cap and after, but the ability to burn isos has always bee provided from the Finder.

Right-click an iso file in the Finder and you’ll see a burn option. More info in this article here.

My favorite Ham Radio apps on MacOS

I have a new MacBook Pro so have been setting up my most commonly used Ham Radio apps from scratch. Having tried various apps for digital modes and logging on the Mac, this time round I’m just installing the ones that I use most or found I preferred.

Here’s my run down of apps:

WSJT-X (https://physics.princeton.edu/pulsar/k1jt/wsjtx.html) for running JT65, JT9 and FT8 digital modes
FLDIGI (http://www.w1hkj.com/) – for all other digital modes, PSK, RTTY etc
For logging from FLDIGI to RUMLog – this script (https://www.machamradio.com/blog/2015/02/27/fldigi-to-rumlogng-applescript-setup/) which can be run as a macro from FLDIGI
JT-Bridge (http://jt-bridge.eller.nu/) – captures log entries from WSJT-X and transfers to RUMLog
RumLogNG (http://www.dl2rum.de/rumsoft/RUMLog.html) – log book app
For contesting: RUMPed and CocoaModem http://www.w7ay.net/site/Applications/cocoaModem/

Installing AWS CLI on MacOS 10.13

The AWS instructions to install the AWS CLI using Python and pip work on MacOS 10.13 (High Sierra) up to the point of adding the Python install location to your path – I found that on 10.13, following the steps didn’t result in the aws command being found.

At the step to addto your path:

running ‘which python’ showed:

$ which python
/usr/bin/python

but, ls -la did not show that this was a symbolic link in my install per the docs, so this location is also not the same location where the pip installed aws command is.

This post has an answer that suggests the issue is because AWS CLI instructions tell you to do:

pip3 install awscli --upgrade --user

but the –user option specifies a user location. To find where the pip install is installing to, do:

python3 -m site --user-base

This told me:

/Users/kev/Library/Python/3.6

So taking a looking in the bin dir in this location, this is where the aws cli ended up. Adding this path to my PATH in my ~/.bash_profile and now aws command works as expected.
