MacOS Arm systems and gatekeeper - How to run unsigned software?

[Friedrich Beckmann]

Hi,

is anybody out there with an Apple M1/M2/M3/M4 ARM based system who can figure 
out how to run the unsigned pspp application build for arm64? The 
pspp-2.0.1-g99436b-2-arm64.dmg is here:

I do not have an apple developer id - so I cannot sign the app. I have an Intel 
based Macbook Pro (Retina 13 inch / Early 2015) running MacOS 12.7.6 and 
therefore I cannot test the changed gatekeeper „features“ to stop people from 
running non Apple approved software. There are various hints you can find via 
google like:

but I cannot test them. A nice step-by-step instruction would be nice.
