you have to know that in some unknow future this application will not work anymore (probably by next years new macOS version, the one after High Sierra).
I have a friend who still use Snow Leopard because some of his softare needs an upgrade (at diamond price / priceless upgrade) and he cannot afford it, but he needs (for his own use) it
PS: I understand your money concern, but the shared price is not the price for building Console applications only. Check the xojo web site for prices.
This is not correct. I have it set to “Anywhere” (in Sierra, must use “sudo spctl --master-disable” to show “Anywhere” option) but the REAL Studio would still not open.
Welcome to the world of code signing, if it was signed way back in 2010, the certificate used then would no longer be valid now, and on top of that the certificate that the certificate would have required has also expired.
Apple not only created a mechanism for ensuring that an app came from who it claims to be from, they also created a solution that can cause older apps to become useless. I’ve lost a bunch of little utilities because of an expiring Apple certificate (that are no longer maintained).
