Verifying Java and RAM before first launch

Open the **Settings** tab inside Edit Instance to confirm your Java installation matches the Minecraft version and set Maximum Memory to 4096 MiB (or 6144–8192 MiB for heavy mod lists).

If a newly added mod causes a crash, untick it in the **Mods** list without deleting the JAR file to test cleanly.
