UPDATE 6 (29/5 23:24 UTC): Login issues should be resolved now.

UPDATE 5 (28/5 10:02 UTC): Mojang is investigating issues with joining multiplayer games.

UPDATE 4 (24/5 23:03 UTC): We're seeing increased reports of players not being able to log in or join multiplayer servers ("Failed to refresh login" / "Failed to login:Invalid Session (try restarting your launcher)"). We've passed this onto Mojang and hopefully they'll investigate.

UPDATE 3 (24/5 09:18 UTC): Services should now be back to normal. If you are still having issues logging in, please see this article on what you can do.

UPDATE 2 (23/5 15:10 UTC): Unfortunately login issues seem to be back - Mojang is currently investigating. You might also not be able to change passwords/emails.

UPDATE: Issues with inviting people to realms should be resolved. If it's still not working for you, please reply with the following information:

1. Your Minecraft username
2. The Minecraft username of the person you're trying to invite
3. Your Realm name

=====

There's been some problems at Mojang's login servers today, which means you may not be able to log into Minecraft at the moment.

Mojang is currently investigating. There is NO ETA when services will be back to normal.

(Earlier on, some users were getting "Invalid IP" errors when trying to log into Minecraft. We're not sure if this is related to the current issues at hand, but Mojang has told us this has been fixed.)

This post will be updated in sync with /r/Minecraft's FAQ Thread. Please do not ask for support in this post; either open a new post or use #minecrafthelp IRC Chat for that.

Known issues:

Issue: Can't connect, download or restore Realms

Mojang is looking into it. For now, email Mojang with your Minecraft username and Realm name to get it fixed.

Bug: When opening a pre-1.13 world in release 1.13, Minecraft's telling me I'm in a snapshot.

This bug has been fixed. MC-133942.

Issue: Minecraft crashing when entering main menu.

Try disabling Discord game overlay, or uninstall Discord. Then check out the My game doesn't respond or crashes upon launching! / My game is performing very poorly. section for more advice.

Issue: Old launchers can't play 1.13 anymore.

This is by design. Please use the latest launcher from minecraft.net/download.

Issue: Random Java crashes when running Minecraft client / server.

Make sure you're using Java 8 update 51 or greater. For the client, you should use the bundled version of Java; see the I'm getting an "Unable to locate the Java runtime" error when trying to run Minecraft. How do I fix this? section to find out how.

For servers, you should uninstall all earlier versions of Java, then reinstall the latest version of Java 8 from here.

Issue: Bad performance when playing 1.13.

Mojang is aware. MC-132135

Check out the My game doesn't respond or crashes upon launching! / My game is performing very poorly. section to see if it's definitely 1.13 or it's just you.

Issue: Minecraft crashing when trying to join a realm.

This has been fixed.

Issue: Pre-1.13 worlds would sometimes fail to convert properly

There have been reports of worlds failing to convert properly. Mojang has been notified of the issue.

Issue: Minecraft crashes when run on older Apple computers running MacOS 10.10 (Yosemite) or lower.

Please check whether your system meets the minimum requirements here. You can check what GPU you have by going to Apple Icon (on the top left) -> About This Mac -> System Report -> Graphics/Displays.

If your GPU does not meet the minimum requirements for Minecraft, you have two options:

• Upgrade to the latest macOS version available for your model
• Stay on 1.12
• Buy a new computer

If your GPU meets the minimum requirements for Minecraft, please PM me with your Model Identifier (Apple Icon (on the top left) -> About This Mac -> System Report) and a crash log, if you have one.

What is The Update Aquatic?

The Update Aquatic the latest update to Minecraft, and the first to be released across multiple Editions (Java, Windows 10, Xbox One, Switch, PS4) almost at the same time. There are new mobs, new items, new blocks, new structures, new biomes, new game mechanics, and lots of water. See here for a taster from Mojang. The complete 1.13 changelog is on the Minecraft website, as well as the Minecraft Wiki.

Other Editions have already seen releases for some of the Update Aquatic content, with more to follow. The aspiration is to eventually release it on all extant Editions of Minecraft.

So what is the biggest change?

As outlined by Mojang, the original plan was to have two separate releases, 1.13 "Technically Updated" and 1.14 "The Update Aquatic". The technical update was required to make it possible to add the new blocks and develop the game's mechanics for The Update Aquatic. For reasons these two were merged into a single version 1.13 combining them both.

• The world save format has changed; worlds older than 1.13 cannot be opened with versions from 1.13 or later without permanently and irreversibly upgrading them to the new format, making it impossible to open them in earlier versions

This update is all about Ocean content. The new Biomes, underwater plants, Fish mobs and Dolphins, structures, will all generate only in new chunks.

How stable is the update?

As with all releases, some showstopper bugs may pop up after the game's release. If you need your game to be stable, it is recommended that you don't upgrade straight away. Instead, wait for a week or two and see if any players report game-breaking bugs, and give time for Mojang to fix them. See How can I stay on 1.12? for more information.

Alternatively, you can backup your worlds by making a copy of your saves folder before upgrading to 1.13, in case anything goes wrong.

What happens when I update my world? Will new ocean content generate in my old world?

Back up your saves. When you first open the world save in 1.13, it will be converted to the new save format and it will over-write the original save.

New content will only appear in newly generated chunks (mainly in Ocean/River Biomes), and will not alter existing chunks (with some exceptions: see below).

How can I delete/reset chunks in my world so they will regenerate in 1.13?

There are several techniques, some more involved than others. Back up your saves first. All of these methods require you to edit the world save before using 1.13.

This is a detailed article on how to use MCEdit and a custom plugin to reset Ocean and River Biome chunks




You can use MCEdit to manually reset chunks, consult the usual MCEdit resources




You can delete chunks using NBTExplorer:




You can fly without a seatbelt, and directly delete files from the save folder by identifying them using Dinnerbone's Co-ordinate Tools (not recommended)

I don't like the new chunks. Can I downgrade my world from 1.13 to 1.12?

As always, downgrading is not, was never and will never be officially supported. Please do not run 1.13 worlds in older versions of Minecraft.

My 1.12 resource pack broke! How do I upgrade them to 1.13?

Because of major texture pack changes in 1.13, a lot of block values have been updated. To fix this, you will need to wait for the resource pack owner to update their resource packs to 1.13.

If you are a resource pack owner, try this tool from Hypixel. Alternatively, see this page on what's changed to what.

My Map Items don't look the same! Has something changed in how they are rendered?

Map Items are rendered differently in 1.13, many blocks that used not to display now display (and some do not display because they are too small).

When will the PS4 and other Legacy Console Editions get this update?

On May 3rd 2018, Mojang officially announced that most Legacy Console editions will be getting the Update Aquatic, but with the exception of PS4 they will receive no further feature updates after this release. All other Legacy Console Editions will cease development.

We don't have a release date yet for PS4. It will likely follow a while after the other Editions.

Work on Update Aquatic for Console Editions is progressing, but it won't be released until after all parts of the update have been released on the Bedrock version.
We don't have a date for when that will be, but we will let you know when it goes in to test.

Where is the Super Duper Graphics Pack DLC?

There's no connection between the Update Aquatic and the Super Duper Graphics Pack. There's no release date yet.

What has happened to the Customized World option? Why can't I migrate my Customized world?

Worlds originally generated using the "Customized World" options can't be opened in 1.13. You can edit the world save level.dat using NBTExplorer to remove the custom settings (change generatorName variable to default, and generatorVersion variable to 1). If loaded in 1.13 you will have the option to use the Optimize World feature to make a world created with the customized option playable in 1.13, but it will use the standard generation.

Why have my commands stopped working? What is the new command syntax?

Many commands have changed syntax, and may have new or changed arguments. Here's an early draft of some of the changes, the Official Wiki page has details of the changes made to commands.

Downloading and Running The Game

What are the minimum system requirements for Minecraft 1.13?

There are no hardware requirement changes for 1.13. If your computer meets the requirement for Minecraft now, it will be able to play 1.13.

However, as 1.13 brings updates to the underlying graphics library, older devices that do not meet the minimum requirements may no longer be able to play Minecraft. These devices are usually over 5 years old and are not built for modern games. In this case, you'll need a new GPU (if you're on a desktop) or a new computer (if you're on a laptop).

You can find the current requirements here.

What's the minimum Java version required for 1.13?

Due to bugs in earlier versions of Java 8, Mojang recommends using the bundled version of Java (1.8.0_51) to ensure maximum compatibility. See this FAQ for instructions to use the bundled version of Java.

Java 9 and later versions are not officially supported at the moment. OpenJDK is also not officially supported - please use Oracle Java to play Minecraft.

My game doesn't respond or crashes upon launching! / My game is performing very poorly.

Try the following:

1. Optimize your world
2. Ensure you don't have any incompatible software installed
3. Ensure you are using the bundled version of Java. Check the I'm getting an "Unable to locate the Java runtime" error when trying to run Minecraft. How do I fix this? section for instructions.
4. Ensure you have the latest graphics drivers
5. Ensure you don't have any other background processes open.
6. Try an ADWCleaner scan. ADWCleaner is an utility to clean a PC which is infested with malware. Download it by clicking here. Run a Scan, Clean anything it finds, restart the computer, and try Minecraft again.

How can I update my graphics drivers?

If you need help with updating graphics drivers, this page will guide you through the process. It also tells you how you can get technical support if you are unsure how to update your graphic drivers.

I'm getting an "Unable to locate the Java runtime" error when trying to run Minecraft. How do I fix this?

If you are getting "Unable to locate the Java runtime" errors when launching the game, head to Launch Options -> turn on Advanced Settings -> click on the profile you intend to use (usually Latest release). The Java executable options should be set to Off (grey). If not, turn it off, Save and restart the launcher.

Why can't I download the new server .jar?

The server .jar download site has changed, but the Launcher hasn't yet been updated. You can download the 1.13 server .jar here.

Why can't I download the new update?

Please see this article for ideas. Additionally, check the incompatible software list below to ensure you don't have any incompatible software installed.

What software might interfere with installing / updating or running Minecraft?

This page, maintained by #minecrafthelp, has tons of information on what software may be interfering with Minecraft.

One particular offender is ByteFence. If you are seeing an error message like this, it's most likely caused by ByteFence. It should be uninstalled from your system.

Error details: Attempting to move successful download to 

C:/Users\User\AppData\Roaming\.minecraft\assets\objects\somethingsomethingsomething

The process cannot access the file because it is being used by another process

Additionally, on some systems or configurations Discord can cause problems. Make sure to disable the Discord in-game overlay. If you use Discord and are experiencing issues and disabling the overlay makes no change, completely close Discord while running Minecraft.

Why does Minecraft "crash" when I switch versions? How do I create a separate folder for new profiles in the Launcher?

If you are getting problems when switching between versions, it usually means that a shared config file is not compatible between versions. To get around that, create each version with a private profile in the Launcher.

How can I stay on 1.12?

You can do that by creating a new launcher profile. Head to Launch Options, click on Add new, give your configuration a name (e.g. 1.12), from the Versiondropdown select release 1.12.2 (do NOT select "Latest Release" as this will upgrade you to 1.13), then click Save.

To launch 1.12, click on the News tab, and the Play button will now have a dropdown button for you to select your profile. Select your new profile, then click "PLAY".

What is the Optimize World option?

Minecraft 1.13 introduced a new world file format. By default, this happens as players visit already-generated chunks; the game will update the world to the newest format on-the-fly. However, the Optimize World option forces the game to upgrade the world in one go, increasing performance in-game.

The game will normally prompt you to backup and optimize your world when loading a pre-1.13 world. However if you want to do this yourself, on the world selection screen you can select the world and hit the Edit button. From there you should select the Backup World option, then the Optimize world option.

When you optimize a world, the game client will create a backup for you and then go through the optimization process. This process will take different amounts of time based on world size and the computer itself.

For servers, you can pass in the --forceUpgrade argument when launching the server to force it to optimize the world (e.g. minecraft_server.jar --forceUpgrade). It is highly recommended that you manually make a copy/backup of your servers world folder before starting that server up in 1.13 if you have not done so already.

I'm still having trouble running Minecraft. What can I do?

You should open a new thread in this forum. You could also try asking the volunteers in the #minecrafthelp IRC channel for help and advice. Please be patient, they are likely to be very busy.

Realms

When will Minecraft Realms update to 1.13? How can I delay updating Realms until I'm ready?

The Realms server version will not update until the owner of the Realm updates and visits the server. At that point the world save will convert. There should still be a 1.12 profile in the owner's Launcher, so they can switch to that and download the Realm save first if required.

I'm receiving a message telling me to get parental consent before I can play Realms? What should I do?

Because of recent changes in EU data protection laws, all minors must obtain parental consent before they can access Realms. See this FAQ for more information

Hi guys! We have been receiving reports of users on old Macs being unable to run Minecraft 1.13, therefore we're investigating if a bump in requirements is needed.

If you have an old Mac (anything released before 2014), we would like to like to know:

1. Can you run Minecraft 1.13 on your Mac? (i.e. no crashing upon launch)
2. Your current macOS Version (Apple Logo on the top left -> About This Mac)
3. Your Model Identifier (Apple Logo on the top left -> About This Mac -> System Report)
4. Your GPU Chipset Model (Apple Logo on the top left -> About This Mac -> System Report -> Graphics/Displays)
5. The latest version of macOS available to you, if you haven't upgraded to the latest version yet (Apple Logo on the top left -> About This Mac -> Software Update)
6. If you aren't able to run Minecraft: Does upgrading your Mac to the latest macOS version fix it?

Thanks for all your help!

Hello Minecrafters! As you probably know (by the amount of spam important privacy policy updates in your email inbox), GDPR (General Data Protection Regulations), a new set of EU data protection laws, recently came into effect on 25th May, 2018. Mojang has been working hard to stay compliant, therefore they've had to make a few tweaks in the system over the past week.

You can read Mojang's official FAQ here, but here's a few more:

1. What does this mean for me?

For most people, nothing. However, if you are considered underage in your country and purchased Minecraft before 25th May 2018, you will no longer be able to play in realms unless you update your account.

2. Wait, what?

If you are considered underage in your country and purchased Minecraft before 25th May 2018, you may see this screen when trying to play on a realm. This means your parents need to provide consent to Mojang.

If this screen does not show up, it means that your account does not need further action.

2a. What is the underage cutoff for my country?

If you are an EU citizen, this would usually be your country's age of consent, typically between 13 and 16 - check this page to find out.

If you are an US citizen, the cutoff is 13, to comply with COPPA.

For other countries, the cutoff is 16.

3. I see the screen you mentioned. What can I do about this?

Very simple: Get your parent to provide consent by clicking this link. (the page looks like this)

Your parents can provide consent either by paying a $0.10, non-refundable fee with a credit card, or by signing a consent form.

The verification process is exactly the same as the one currently used to verify accounts affected by US's COPPA laws. You can read about the existing process here.

4. Is this common practice? Does Mojang make money off this?

This method of obtaining parental consent is popular amongst companies, and is the most widely used one. As processing this transaction cost Mojang more than $0.1, Mojang does not make any profit from this.

Alternatively, you can also sign a consent form and return this to Mojang, free of charge (minus printing and postage, if applicable). The form can be obtained by contacting Mojang Support. You can either post the consent form, or scan/photograph it and email it to Mojang.

5. My child has a Minecraft.net account (They use their username to log in). Can I provide consent for this account?

No. You must first migrate your account to Mojang Account, then you can provide consent. (You should definitely migrate. Check out this help article on reasons why.)

6. I already provided parental consent for my child for COPPA. Do I need to do this again?

No. Parental consent only needs to be given once.

If you are being asked to provide consent again, please contact Mojang Support.

7. I'm thinking of buying Minecraft for another child. Do I need to go through this verification process?

If you provide parental consent when purchasing Minecraft, you won't need to go through this process again, and the $0.10 fee won't apply to you.

If you are being asked to provide consent again, please contact Mojang Support.

8. I remember a thing called Snooper that sent my PC's specs to Mojang. Is this still turned on?

Snooper is still here. You can always opt out in Settings -> Snooper Settings in the game.

Additionally, Minecraft Hopper is still collecting crashes, but these reports, like Snooper reports, do not contain personal information.

9. Ocelot?

Meow.

Happy Minecrafting!

Your CPU was released 7 years ago. This should be a pretty good indicator of how powerful it is.

1. Downgrading

As always, downgrading is not, was never and will never be officially supported! Please do not run 1.10 worlds in 1.9, 1.9 worlds in 1.8, etc.

2. Intel Integrated GPU and random crashing (MC-32606)
Some people with Intel integrated GPUs may see the game crashing from memory access violations. The crash log looks like this:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00007ffb84b1172c, pid=7928, tid=9892
#
# JRE version: Java(TM) SE Runtime Environment (8.0_25-b18) (build 1.8.0_25-b18)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.25-b02 mixed mode windows-amd64 compressed oops)
# Problematic frame:
# C  [ig8icd64.dll+0x60172c]
#
# Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
#
# If you would like to submit a bug report, please visit:
#   http://bugreport.sun.com/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
#

This is because of a memory leak caused by Intel's drivers (i.e. faulty drivers). This mainly affects 7th to 9th Generation Intel HD Graphics (ig7xxxxx.dll, ig8xxxxx.dll, ig9xxxxx.dll), which ships with 3rd Generation to 6th Generation Intel Core Processors. In layman's terms, if your Intel CPU is Ivy Bridge (Model number ix-3xxx), Haswell (4xxx), Broadwell (5xxx) or Skylake (6xxx), you may be affected.

To work around this issue, make sure you have the latest drivers installed and set VBO and VSync to On in Video Settings (Options -> Video Settings -> Use VSync/Use VBO -> On). Additionally, try allocating more RAM to Minecraft.

3. OpenGL Requirements

The OpenGL requirement for 1.9/1.10 stays at OpenGL 1.3 (from internal sources).

4. Graphics Glitching For No Reason After Upgrading

Minecraft 1.9 makes use of even more advanced OpenGL features than before. If your graphics suddenly started giltching since upgrading to 1.9, chances are that your graphics drivers are out of date.

Make sure you have the latest drivers installed and set VBO and VSync to On and set Mipmap to 0 in Video Settings (Options -> Video Settings -> Use VSync/Use VBO -> On) If you are on a laptop with switchable graphics, you may also want to check that your computer is indeed using the dedicated graphics card.

Nvidia Optimus Instructions

AMD Switchable Graphics Instructions

(Bug report pertaining AMD GPUs here)

5. Getting random block lag?

If you are suddenly getting block lag in 1.9, try lowering your render distance in Video Settings (Options -> Video Settings) to something below 16 chunks. Also, try allocating more RAM to Minecraft.

Common Issues We Are Aware Of

Here are some common issues we are aware of that is not listed above. We at #MinecraftHelp are constantly investigating the cause.
