When trying to install forge on my mac, I found that all versions from 1.13 to the latest (1.15.2), I can easily download and install and they work as they should. For 1.12.2 and older however, when I try to open the installer it opens then closes and gives me an error message saying:" The Java JAR file “forge-1.12.2-14.23.5.2768-installer.jar” could not be launched. " I've looked it up and tried manny times to no avail If anyone could tell me what I'm doing wrong that would be great thanks.
