Before anyone can help players in the Minecraft Discord channel or Minecraft Forums, please make sure that the following has been performed so that we can eliminate these as possibilities. The player would be surprised how many problems these simple suggestions fix.

Note that no community channel is able to help players with account issues. For those, see the help website.

  • Make sure the machine meets the specifications provided by Mojang here.
  • Make sure the player is running the latest version of Java 8. On GNU/Linux, OpenJDK works as well but is not supported by Mojang. Headless (GUI-less) versions obviously can not run the game.
  • If you are experiencing weird behavior and are using the most recent Java, try reinstalling Minecraft (see below)
  • Some graphical issues may be related to old or outdated graphical drivers, make sure these are up to date from the manufacturer website. Windows update/device manager don't always install the correct ones.
  • If you are playing on a laptop/notebook/tablet or any other mobile device, make sure to be in high-performance mode rather than energy saving mode.
  • Make sure that your OS, in general, is up to date.
    • Windows: Windows Update
    • macOS: Software Update
    • Debian-based GNU/Linux distributions (such as Ubuntu or Linux Mint): in a terminal: sudo apt update && sudo apt upgrade
    • RedHat-based GNU/Linux distributions: yum update
    • Arch-based Linux systems: pacman -Syu

If the player still have issues after this point, and none of the basic answers below can solve the problem, then make sure the following have been done:

  • If the game is crashing, copy and paste the crash log into Ubuntu Paste and copy the link into the channel with a description of your problem.
  • Please be patient, the people the help in this channel are volunteering their expertise. Also, all help in the channel is considered "best effort"

Common fixes[edit]

Reinstalling Minecraft[edit]

One of the common ways to fix an ailing Minecraft installation of various bugs is to simply re-install it. Removing the launcher itself (the file you downloaded) however will not remove Minecraft. The steps below should work for most people.
Important step: Be sure to do a forced update if you still have issues.

Windows[edit]

  1. Navigate to your Application Data Folder: %AppData%
  2. Double Click the .minecraft folder
  3. Copy out the saves folder to a different location
  4. Go back one directory (to where you can see .minecraft)
  5. Drag the .minecraft folder into the trash
  6. Start the Minecraft.exe file to re-download Minecraft
  7. Close Minecraft when you reach the title screen
  8. Copy the saves folder back into the new .minecraft folder. You can safely overwrite any data that's currently in this folder

GNU/Linux[edit]

  1. Open a terminal
  2. Copy and Paste the following, one at a time, into the terminal to delete the current minecraft installation and retain the current saved worlds.
  3. (Do not remove files to the /tmp directory, things can get randomly cleared. It is generally bad practice to do so)
$ mv -v ~/.minecraft/saves ~/saves.old/

Be careful, do not continue if your terminal gives you an error. The next command deletes your minecraft folder so if the prior command did not work all your hard work would be lost! Do NOT Run this under sudo or the root user

$ rm -rf ~/.minecraft/*
$ mv ~/saves.old/saves ~/.minecraft/saves
$ rm -rf ~/saves.old
  1. Start Minecraft like you normally would. Your saves should be intact and the Minecraft client will re-download itself for you.

Alternatively, open up your Home folder and press Ctrl+H. This shows all hidden files and folders. Navigate down to .minecraft. From here, you can work in essentially the same way as outlined in the instructions for Windows above.

MacOS[edit]

  1. Open a Finder window
  2. Click the Go Menu item and Click Go to Folder
  3. Type ~/Library/Application Support/minecraft into the text field and click Go
  4. Drag the saves folder to your desktop
  5. Drag everything else in the minecraft folder to the trash
  6. Drag the saves folder back into the minecraft folder
  7. Close the Finder window and launch the Minecraft App just like you would normally.

Latest Version[edit]

If you are having issues after a reinstall, or are having other client issues, you can try using forced update.

  1. Open the Minecraft launcher
  2. Click on the arrow (directly beside the version)
  3. Click on "Latest Version!"
  4. Click on "Play"
  5. Soon, the client will re-download the game files

Reinstalling/Updating Java[edit]

  • If Minecraft is not working due to an issue with Java, your Java install may be corrupt and/or out of date. To remedy a corrupt install, begin by uninstalling Java. After the uninstall is complete, you can then try reinstalling.
  • For Windows users, it is sometimes (rarely) necessary to use an uninstaller program, such as Revo Uninstaller (free) to remove Java. Revo will search in-depth for all things Java, and remove the files.
  • To re-download/update Java, visit Java's download page here. Download the correct version (of Java 8) for your machine, based on what operating system you have.
  • Make sure you be careful with all instructions! (Anyone can edit this page)

Updating video drivers ("Bad video card drivers!"... et alia)[edit]

  • If Minecraft has poor performance, has graphics that are distorted, or is simply not working, it's possible that you need a driver or an updated driver installed.
  • Some graphics cards only accept drivers from the manufacturer of the computer (i.e. Dell, HP, Toshiba). Visit the support site of the company that affects you, if that ends up being the case for you.
  • Windows Update is not a good method for updating video drivers. If a generic driver is installed, you should remove it before installing a new driver. Create a system restore point, or perform a driver rollback if you experience issues after installing a new driver.

It has been suggested that this page be merged with Tutorials/Saved data Dropbox guide. [discuss]

The following steps will link your .minecraft/saves folder with a Dropbox account. The way in which you do this depends on your OS. Please note that dropbox provides 2GB of free storage, after which you will have to pay a monthly subscription fee to expand your storage. Google Drive gives you 15GB of free storage.

The following steps assume that you have set Dropbox up to use the default folder and that you have not changed the .minecraft folder. Make sure that Minecraft and the Minecraft Launcher are closed before proceeding.

GNU/Linux[edit]
  1. Open a terminal window.
  2. Paste the following into your terminal:
mv ~/.minecraft/saves ~/Dropbox/Minecraft; ln -s $HOME/Dropbox/Minecraft $HOME/.minecraft/saves
  1. Close the terminal
macOS[edit]

This takes advantage of some of the UNIX underpinnings of the OS.

  1. Open a terminal window.
  2. Paste the following into your terminal:
mv ~/Library/"Application Support"/minecraft/saves ~/Dropbox/Minecraft;ln -s $HOME/Dropbox/Minecraft $HOME/Library/"Application Support"/minecraft/saves
  1. Close the terminal.
Windows Vista, 7 and 8[edit]

This uses symbolic links so you will need to get under the hood a little bit.

  1. Open File Explorer, and navigate to %AppData%\.minecraft
  2. Open a second File Explorer window with the My Dropbox folder open
  3. Move the saves folder in the .minecraft window to the My Dropbox window
  4. Rename the saves folder to Minecraft
  5. Close both Fie Explorer windows
  6. Go to Start → Run and type CMD and hit enter. (You may need to run the command prompt as an administrator.)
  7. Type the following: (Be sure to double-check the path to your Dropbox folder.)
mklink /d %AppData%\.minecraft\saves %HomePath%\Documents\Dropbox\Minecraft
  1. Close the Command Prompt window.
Windows 2000 and XP[edit]

The contents of this section are not supported by Mojang Studios or the Minecraft Wiki.

This uses symbolic links so you will need to get under the hood a little bit.

  1. Download Junction from Microsoft's site and install it.
  2. Open a new File Explorer window
  3. Go to %AppData%\.minecraft
  4. Open a second File Explorer window with the Dropbox folder open
  5. Move the saves Folder in the .minecraft window to the Dropbox window
  6. Rename the saves Folder to Minecraft

  8. Open the Start Menu, type cmd and hit enter.
  9. Type the following:
junction -d %AppData%\.minecraft\saves "%HomePath%\My Documents\Dropbox\Minecraft"
  1. Close the Command Prompt window.

Manual Syncing[edit]

If you want to simply manually back them up for later use, you can either copy out the whole saves folder or just the world folder that you want to backup. If you want to move the order to the worlds in the saved menu, just change the number at the end of the world folder name to adjust the order as you would like.
