my parents are seperated and i have two computers. I would like to be able to play my modded minecraft pack at both houses.
Use MultiMC and install Minecraft on an external SSD for example, then you can take your modded Minecraft to both places and play, on the same world with the same mods. You can also install MultiMC on that external drive. I think that is currently your best option. USB 3 interfaces have become fast enough to handle this.
