Other errors
1. First time? Please wait: on the first launch, the game files download first, so Minecraft can take a few minutes to appear. Keep the Aleph Kids app open while it loads.
2. Quit everything and start again: if the screen stays black for more than 1–2 minutes, fully quit Minecraft and the Aleph Kids app (on a Mac, press ⌘+Q). Close other programs too, then open only the Aleph Kids app and tap Start class. Files that were half downloaded continue from where they stopped.
3. Deleted the official Minecraft on a Mac? Reinstall the official Minecraft (Java Edition) from minecraft.net, run it once until the game's main screen, then quit it. Then start the class again in the Aleph Kids app. You only need to do this once.
4. Still black? Contact support. Tell us when the class was, and the class code if you have it, so we can check faster.
