LD44 - Overburnt Mac OS
Officially, the operating system that was available on that Mac at the time that you bought it is the oldest version of macOS that can run on that Mac. It's likely that an older OS won't include. I'm having a lot of trouble compiling the otherwise excellent Contiki OS on my macbook pro (with mac os x 10.6). Contiki actually uses a lot of GNU-specific features and options of GCC, AR, LD, and so on.
LightBurn talks directly to your laser, without the use of additional software.
We currently support most Ruida, Trocen, TopWisdom, and GCode based controllers. Supported GCode controllers,include Grbl, Smoothieware, Grbl-LPC, and Marlin. Supported Ruida controllers include the RDC6442G/S, RDC6445G, RDC6332G, RDLC-320A, and R5-DSP. Supported Trocen controllers include the AWC708C, AWC608, and TL-3120. More controllers will be added soon, so if you don't see yours listed, send us a message - maybe we're already working on it!
Ld44 Over Burnt Mac Os X
If your controller is GCode, Ruida, Trocen, or TopWisdom based, even if it's not listed it might be supported already - Download the free trial and try it for yourself. If it doesn't work, sometimes it only takes a day or two to make the required changes to support a new board in these existing families.
Please note that LightBurn does not support the stock M2-Nano board in the popular K40 laser. This board does not offer control of power through software - we recommend upgrading the board to take full advantage of LightBurn.
Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience.
Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS.
If you get an alert about a 32-bit app
You will see one of these alerts when attempting to open a 32-bit app:
[app name] needs to be updated.
The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.

[app name] is not optimized for your Mac and needs to be updated.
This app will not work with future versions of macOS and needs to be updated to improve compatibility. Contact the developer for more information.
When installing macOS, you may see a list of recently used apps that are 32-bit. You can review this list before deciding to continue installation. You may also see a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.
For all 32-bit apps, please contact the developer of the app to learn whether an updated version of their software is available or planned.
