When trying to open the Makertech Cura, It is not opening. It is showing corrupt.
I've confirmed this on two separate Macbooks. BTW, this shows that I tried to open from the dmg. I also tried after copying from dmg to the app folder. the only difference was that is said move to trash.
is anyone having any luck opening the cure download?

@Makertech 3D ,
Please just provide the proper Start G-Code and End G-Code so we can insert that into our favorite slicer. Along with other speed and jerk settings.
You will not be able to keep up with all the updates using your custom version of Cura. They are already on v5 and you don't even have v4.13 out.
Many of us may prefer PrusaSlicer or Slic3r.
This worked for me on Catalina.
Follow all indicated steps to install and patch Cura up to the moment where you open it and get the error message the package is damaged.
Dismiss that error.
Open a terminal window and execute:
sudo xattr -rds com.apple.quarantine /Applications/Ultimaker\ Cura.app
You can now open Cura.
Enjoy!

A mac solution will be available soon. Currently we recommend that you use ultimaker Cura or Slic3r and manually enter in parameters for the Proforge 2S build volume.
I can confirm Andrew Leroy's finding's the workaround doesn't work.
Sadly when installing it replaced a previously functional (at least it had been working on Mojave)
Do you guys own a mac? Have you tried to download it yourself? It doesn't work.
That work around has worked with other apps on Catalina, but it's not working for yours. Please look into the issue.
We'll be looking get the software working natively on Catalina for the next release however in the meantime there's an article here which explains a possible work around:

I've installed the regular Ultimaker Cura and added a custom printer with the same details as in the Makertech Cura (as I'm on MacOS Catalina and that is the only laptop I have available anywhere near my printer. ) I'm not hopeful of getting an updated Makertech Cura at any point and (other than the background image of the Proforge behind the print area) I haven't yet found any meaningful difference why anyone can't just use the Ultimaker Cura.
These are the default printer settings,
I've modified the startup and end G-Code, which is up on GitHub at https://github.com/agarthetiger/proforge-2s-g-code
Unfortunately I can't see a way to export the printer settings in the same way you can for the profiles and materials, otherwise I'd post that here. It doesn't take too long to add the printer into Ultimaker Cura.
doesn't seem to work on my Catalina install anymore, any suggestions, or is there going to be a new release anytime soon?
that worked... running my first full benchy boat now. now just tweaking the belt and roller tension. but other than the fans, its amazingly quiet.
This is a known issue, it needs updating on the build manual too, but it's showing this error because of the mac firewall, here's an article showing how to get around it.
