Boardspace from MacOS
Preferred: Boardspace.net uses a launcher app, which can be installed from the official Macintosh App Store, found here the app bundles it's own java runtime
and
runs in a sandbox. Just install, and run from the macintosh
launcher icon. You can find it in /Applications/ if you want to
make your own
desktop link to it. Once installed and launched, you'll need to log in to play online.
That's the simple way. Otherwise, you'll need to start by installing Java. If you do not have java yet, visit Java.com, download and install it.
This page
has other information about getting java installed and configured on
your computer.
The
actual boardspace application is a set of java ".jar" files which are
downloaded once and cached locally. There are three variant
launchers
that take care of the details, and also keep your local copy up to date
with the current version. Whever method you choose,
you'll have to cope with windows efforts to prevent you being tricked in to downloading malware.
For the record: boardspace isn't malware, doesn't damage your PC, and won't annoy you with advertising.
Method #1: Download this MacOS disk image 
. Open the disk image, and drag the boardspace app anywhere. Your desktop is a good place.
When you try to open the app, you'll probably see a window similar to this.
.
Click on the ?, or The first time you click to run the executable, use CONTROL-CLICK
and select "Open". You will probably see a scary pop-up similar
to this, which outlines the rest of the process to approve running the
app.
the final step is to launch the security control panel, and allow third party apps to run
Method #2: Use
to
launch
the boardspace.net client. Your browser may resist java web start, or may offer
to
save a file instead. You can click to launch a ".jnlp" file that
was downloaded. The first time you launch java web start,
you will see a security pop-up warning about running untrusted applications. Click on the ? in the warning window for
instructions how to give permission.
Also
note that Java Web Start has been deprecated by Oracle is in the
process of disappearing. There's an open source alternative
https://openwebstart.com/ . Download and install Open web start, and Java Web Start will still work.
Method #3: Jar files are directly executable; it's all really the same under the hood, but you don't get a pretty icon by default.
You can download the launcher jar file, place it anywhere, and click to launch it. You can also copy this exact jar file to a
Macintosh
or a Linux PC and launch it there, or launch it from a command
line similar to "java -jar boardspace.jar".
Whichever of these hoops you choose to jump through, when you run the launcher application you should see a window
similar
to this, and you're on your way. Eventually you will want to
create an account (it's free) but the first time you can
check the "guest" box and log in as an anonymous guest.
It's also possible to play offline, all players sharing the screen.
