Latest java is the issue. Use 8u251 max. Link to said java: https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg

Ah yes, there's indeed some sketchy things in there. Don't use a cracked launcher.

It would also help to have a download link to the modpack so I/we can see if you did the rest correctly.

Instead of posting, you could've bothered to check the file, see if there's anything related to the mojang authserver in there, and then just removed the file/line and checked if it fixed it. But no, you had to necro a year old post offering nothing in terms of information.

You extracted the forge installer. That's wrong, you need to rename the installer itself to modpack.jar. The launcher does the installing for you.

"1.0 (1.8.0_281)" Would probably help if you selected the 8u251 under Launcher Options > Java Settings.

Well, you have these pixies, they look like pink fairies. They spawn on the ground, then fly away. There's no spawn limit. You can see where that's going, right? Its a bit like tropicraft, except it takes 2 minutes, and is so much worse...

Disable the Fish Entities in the Openblocks config. You can get the actual name by doing /cofh killall ingame. Try doing that not on your own world, but on a creative singleplayer, as it kills most other mobs as well. ...Just wait till you manage to get to the Promised Lands...

Remove your "Latest" Java, use this java instead: https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg This thread will either be locked for being in the wrong section, or moved for being in the wrong section.

Go here: " '[minecraft_dir]/saves/mapwriter_sp_worlds/[save dir]/mapwriter.cfg:1 Delete that config file. You will lose the waypoints on your minimap.

Tekkit Classic is impossibly hard to install on the vanilla launcher as it: 1. Requires a forge build that's not available (uses a custom forge 176 based on forge 164). 2. The custom forge has some mods added to it, likely in a specific order to prevent mod conflicts. Tekkit Classic is essentially the worst modpack to try to put on the vanilla launcher. You'll be looking at Hexxit minimum for it to be easier, and I have managed to use the vanilla launcher for Attack of the Bteam, so Tekkit Main or Tekkit Legends should possible too. Regardless, it took some swearing.

Your dropbox file and the one distributed with your modpack do not match. This makes my testing a bit harder.

So you are saying we should just allow every cracked person on the launcher?

Looks like you enabled 3D mode.

Actually check if you are never going above 10% graphics usage by making sure the checking is set to CUDA, instead of 3D.

Login password on a server? What are you playing, cracked?

Read the announcements.

Forge update 1.12.2 - 14.23.5.2851 changed things. You need the Forge Installer renamed as modpack instead of Universal. Download and rename the Installer, DO NOT run/install/extract the installer.

Remove java 8u271/261, install and use 8u251: https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg

Remove java 8u271/261, install and use 8u251: https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg

Ah yes, a cracked launcher. To say it nice: Buy minecraft when microsoft accounts are supported.

Remove java 8u271. Install java 8u251. https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg

Same, but 1.13+ Server Forge logs suck, even more than the 1.12.2 and lower Forge server logs...

For 1.13+, you need to use the Forge Installer, which you download, then rename to modpack.jar. You do NOT extract/install/whatever.

Do people even READ THE ANNOUNCEMENTS?
