Console output

Silicon Macs have inverted blue/red colors, for now you can only bypass this by going fullscreen
Earlier versions of Windows (like XP) may work, so long as the Java they run on can handle TLSv1.3 for official Microsoft/Mojang links. There's no guarantee that the launcher will work in full. Earliest Java updates to support TLSv1.3 are 8u181, 7u191 and 6u201
