I'm confused on my purchase of the PC java version. When I purchased it, it indicated that it also included a Windows 10 version of this. For one, my son and I share profiles on MacOS. Each time we switch profiles, the game will not stay signed in under my profile. Eventually, either for him or for me we will be prompted to sign in and the password will not work. It's the same computer here, same install - should be same license from terms I read. Why does this occur and how do we properly ensure we can logon under the same game profile regardless of if he or I should log on at console.
Second thought. It seems that a Windows 10 version was also provided. This is only myself and my son playing, more so he than I. Has anyone tried having a single multiplayer session (like LAN party) let's say with you (the PC version) as the host and a Windows 10 client joining you? Is this possible for my son and I to build in a single world on my PC without the Realms thing (I have plenty of servers too) or if I too play as a PC client and he as a Windows 10 client?
I'd like to understand the license issue and why it keeps losing my game info between switching profiles (even when the game was not running), why I must essentially reset it in order to logon again normally and if or why it would not be possible to use the Java version and the Windows 10 version both using the same game profile but multiplayer together?
I don't know anything about MacOS so hopefully someone else will be able to help you with that.
As for the Java Edition and Windows 10 Edition... No, they cannot play together. They are two different versions of the game and are not compatible with each other. Java Edition can only play with other Java Edition players and servers.
Windows 10 edition is another story. It is part of the "Better Together Update" and will play with other devices that use the same Bedrock Engine. Any version of the game that uses the Bedrock Engine is now called "Minecraft", while the original Java version is now called "Minecraft: Java Edition".
So, the versions that can play together are:
Later this year the Nintendo Switch will also be updated to the Bedrock Engine and get included in this list.
