have a lenovo ideapad 330 15ikb (specs below). I'm currently running Olarila's Mojave 10.14.6. I'm not an expert by any means and dont know what DSDT is and how any of that works. I found a tutorial online and followed and that's about it. I wanna upgrade from mojave to catalina or perhaps big sur if the betas are stable but I'm not able to find a single guide to help me.
