Lightwright is NOT Compatible With Vectorworks Project Sharing
Lightwright 5 and 6 work great with Vectorworks 2016 and later, except for Vectorworks’ new Project Sharing feature. It is unlikely that Data Exchange will ever work with Project Sharing.
"MAY AFFECT THE PERFORMANCE OF YOUR MAC"
You may get a warning when Lightwright launches that it “may affect the performance of your Mac” and “The developer of this app needs to update it to improve its compatibility.”
You get this warning because Lightwright is a 32bit app and Apple is trying to get everyone to 64bit. Lightwright will be transitioning to 64 bit this summer.
You do not need to do anything at this time.
DATA EXCHANGE ERRATIC
If you find Data Exchange disconnecting randomly or causing Lightwright to freeze up while reading/writing the .xml file, try going to System Preferences and turning off the option that moves your Desktop and Documents folder to iCloud. This option is ON by default and causes problems in the same way that putting the .xml file on Droipbox does.
Lightwright 5 is NOT compatible with macOS Sierra or newer
I knew this would happen eventually, but not exactly when. Lightwright 5's time on the Mac just ran out. LW5 is built with tools that were current in 2009, but cannot be used to build modern Sierra-or-later compatible apps. I can't move it to the current tools without breaking mountains of code, which is one very big reason why LW6 had to be released before Apple released Sierra.

A public beta of the next Lightwright maintenance release is available for anyone to try.
Lightwright 6 on macOS High Sierra & Mojave
Lightwright 6 and Vectorworks 2018 SP2 or Later
There were bugs in Vectorworks 2018 SP1 and earlier (including VW 2017 and 2016) that blocked users from entering data in all 3 of the Vectorworks Universe, U Address, and Dimmer fields. This kept Lightwright 6 from properly syncing those fields with Lightwright 6's related fields.
VW2018 SP2 fixes this problem by enabling free entry of data in all three fields. For more information, please read the Addresses and Lightwright 6 topic in this web site's Support menu.
Lightwright 6 minimum system requirements are changing
Due to changes in macOS, beginning with Lightwright 6.0.30, the minimum system requirement for the Macintosh will be mac OS 10.10 "Yosemite". Versions 6.0.21 and earlier will continue to run on mac OS 10.7 or newer. The Windows version's system requirements are not likely to change.

This is a CRITICAL UPDATE that fixes bugs in saving institutional registration info, Eos groups connection, focus charts printing, and other important areas.
A complete list of bugs fixed is available in the Release Notes.pdf in Lightwight 6.0.21's Help menu.
Lightwright 6.0.21 CURRENT RELEASE
Lightwright 6 is NOT compatible with macOS Catalina
macOS 10.15, a.k.a. Catalina, will not run any 32-bit apps, including all current and older versions of Lightwright. A 64-bit release of Lightwright 6 (version 6.0.30) that will run on Catalina is almost ready for beta testing for both macOS and Windows, but there is no firm release date yet, except to say "hopefully by the end of October or early November".
So if you are a Mac user, DO NOT UPGRADE TO CATALINA until Lightwright 6.0.30 is available.
Lightwright 6 and Vectorworks 2020
The way Vectorworks 2020 handles DMX Addresses is new, there are now separate fields for Absolute Address, Universe, and DMX Address. Like the corresponding Lightwright address fields, they are linked to each other so changing any one of them automatically changes the others.
Unfortunately, Lightwright won't be able to take advantage of these new fields until its 64-bit release, and even then there is a bug in Vectorworks 2020 that prevents it from accurately sending any of these address fields to Lightwright except when you do a "Complete Export on Exit". That bug will be fixed in VW2020 SP2, scheduled for release in November.
