So, I’ve had KSP on my MacBook for a year and a half now. The computer is kinda old and clunky but up until recently, it has run the game relatively well. However, ever since the 1.8 update, I haven’t been able to load the game; it gets stuck in “Breaking Ground SquadExpansion/Serenity” and it just stays there without loading the game. I’ve tried re-installing KSP and it still doesn’t work. Any help is appreciated.
