Forge 1.12.2 crashing on Mac, strange error, could I get help with this?

Start new topic

Posted October 15, 20186 yr

So I was starting up Forge 1.12.2 on my Macbook Pro with 6gb of RAM dedicated to Minecraft. But it crashes for no reason. I heard Optifine was a main issue, so I removed it, but my game still crashes. Here is the crash text that I took from my game output:

You have a misbehaving coremod.

Can't tell much else without a full log and it would be tricky even with one

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/: 100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler

Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
Make a launcher profile targeting this version of Forge.
Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

Video:

Spoiler

or alternately,

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

Open a command prompt (CMD, Powershell, Terminal, etc).
Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
Run the following commands:
1. git init
2. git remote add origin [Your Repository's URL]
  - In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
3. git fetch
4. git checkout --track origin/master
5. git stage *
6. git commit -m "[Your commit message]"
7. git push
Navigate to GitHub and you should now see most of the files.
- note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
Now you can share your GitHub link with those who you are asking for help.

What coremod do you think it is? Are there any coremods that have histories of misbehaving?

October 15, 20186 yr

Any coremod that's doing things wrong could cause this.

II would need your full log to determine anything further, check the Log section of my signature for more information on submitting the correct log.

You should really create your own post instead of digging up a post from a year and a half ago.

That being said, 1.12 is no longer supported due to age. To receive support, you will need to update to a modern (1.14.4/1.15.2) version. See the LTS link at the top of every page for more information on supported versions.

There's nothing stopping you from doing so, however if you have problems you won't be able to ask for help here. For old versions you could try the official minecraft forums, I know they have a modded section over there, I just don't know what it's like, as I don't go there.

There are tons of good mods for current versions, it might be time to let go of old outdated mods that have been abandoned and don't get updated to current versions!

made a modpack but i get this error every time i try to launch minecraft

[main/ERROR]:Failed reading REFMAP JSON from : java.lang.NullPointerException Cannot invoke "org.spongepowered.asm.mixin.refmap.ReferenceMapper.setResourceName(String)" because "mapper" is null

this is the error message i keep getting when trying to launch minecraft from the launcher with my mods but i just can't figure out what this error message means. i'm new to making mod packs but i have tried making 3 separate mod packs with different mods but i still run into this issue and i am starting to think there might be a conflict between 2 different mods but again i have no idea since this is the only error message i get. any idea's?

The game crashed: rendering overlay Error: com.electronwill.nightconfig.core.io.WritingException: An I/O error occured

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

How Do I Commission A Mod

There typically isnt a place to commission mods. Mods are made by hobbyist programmers in their spair time. You could try some general minecraft modding discords, but I dont have any to recommend.

jarJar not working

minecraftLibrary is required for dev time for it to load.
jarJar should be enough for runtime.
be sure you're running the latest forge. And make sure you post your debug log.
