Ok. But any ideas on how to fix the problem?

No sorry, I changed it to 128 for a minute to test something. Now it just stops at 3/6 and at textures, with or without the first part. And there is a environment variable set up for Java. I can't even try a different version of forge... the installer won't even open.

PsychoCreator, for people to asses your problem, you're going to need to post a crash log. On Macs, crash logs are stored at: ~/Library/Application Support/minecraft/crash-reports You can open one of those and put it on pastebin and show it to us.

In the Java argument, it only shows one in the client. "-Xmx4G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M" Do you mean remove the "-Xmx4G"? I'll try that.

What do you mean? Should I crank the RAM on that one?

So I'm installing Minecraft with mods on 3 computers so my brothers and I can all play together. One is an iMac, which works fine with the mods and is very fast, next is a Swift 3 laptop and also works well. Then theres a Lenovo laptop that has had some troubles. I'm actually suprised, because the Lenovo laptop has the best CPU and Ram. It has an Intel i7 Core, and 12 Gigs of RAM, while the mac has an intel 4th gen and 8 Gigs. I keep allocating memory to it, even 4 gigs, and it still isn't working! The computer is pretty fast, and loads minecraft without mods completely fine. It always says: The game crashed whilst initializing gameError: java.lang.OutOfMemoryError: Java heap space Crash Log (minecraft): https://pastebin.com/Wmug3KBF If you need anything else tell me, please help. By the way, yes, my Intel HD Drivers are up to date.
