That depends if the mods are for forge or not, if they are, then yes you need forge. The mod overview/description should say if it's a forge mod or not.

You should not bump a thread after only an hour, that's not polite forums etiquette. Anyhow, if you read your log, it tells you what the problem is.

Optifine for 1.14.2 is not compatible with forge at this time. Check the Optifine Changelog for information on forge compatibility. As far as your capes mod, hard to tell without logfiles. If you google "macos minecraft logs folder" you could probably find instructions on how to find the logs folder to post for us. I do not use a mac, so cannot help you with that part.

How did you fix it? Just curious, and it might also help someone else searching through the forums in the future.

Well, that blur mod won't work with forge, it's for fabric. So is the brightness mod. The changelog for the version of optifine you are using (changelogs are linked on the downloads page) says it is not compatible with forge.

What mods are you using? And where did you get them? Unfortunately the crashlog does not show any of that information.

Optifine is pretty specific about the versions of forge it is compatible with, checking optifine's changelog will usually tell what forge build it works with.

If it were me, I'd try removing the movingworld mod, and see if that stops the crashing. Also make sure you are downloading your mods from curseforge, or directly from the developers, and not from shady websites like 9 minecraft and such.

Just as a side note, after java, it should be -jar, not just - before the jarfile name. That's why it said: So it should have looked like this:

Don't download from 9minecraft, they distribute mods without permission, and there is the potential for there to be malware added to the mod jars, as well as potentially out of date mods. I would delete any mods downloaded from 9minecraft and redownload them from curseforge. https://stopmodreposts.org/

Make sure the mods you are downloading are actually for forge, and not fabric (or another modloader). From my limited browsing/searching of curseforge, not a whole lot of forge mods are updated for 1.14.2 yet, and seems as if there are more for fabric (currently).

https://minecraft.curseforge.com/mc-mods Keep in mind that most of the forge mods are currently 1.12.2, as there is no RB for higher versions yet, and I imagine mod authors are waiting for things to settle down before investing in the new versions. Be careful where you download mods from as well, I would only download from curseforge or a developers actual website/github.

In your screenshot I see a cascading worldgen message from additionalstructures. Also see ic2 and forestry mentioned in the crashlog. I'd start by removing 1 or more of them, and seeing if it still has issues keeping up, if you haven't already.

Are you sure the command prompt is in the folder where the jar file exists? "dir" (without the quotes) will show a listing of the files there. If it is there/still cannot access it, then I'm not sure, possibly some sort of permissions error or file corruption.

I think the problem is the version of Optifine you are using is for forge 2729, and you are using forge 2838. From what I understand, when using optifine you must make sure you are using the version that is compatible with the version of forge you are using (check the optifine changelogs, it tells what version of forge it is compatible with)

Open a command prompt at the folder where your jar files are located, and try running java -jar <name of jar file>, i.e. java -jar forge_installer.jar You should be able to see what it's trying to tell you this way without the window closing on you.

It tells you what is wrong right at the top of the log, I know they can be long and scary looking, but just read it line by line carefully, and sometimes the answer is that simple.

I would guess something is broken with applied fluidics, try removing it and see if if you still have a problem. If so, post new logs.

Versions as old as 1.7.10 are no longer supported on here due to age, you will need to update to a more recent version if you want support. A moderator will likely lock this thread once it has been seen.

Very weird, it's clearly showing in the log that that mod is present, and it's part of the error in the crash. You downloaded the mods from a legit location, like curseforge, and not a shady site like the one that starts with 9, right? Not really sure what else it could be, unless maybe your game directories are mixed up or something.

If you remove the structurize mod, does it load? Looks like the errors could be coming from there.

Did you try running it without sudo? I don't know if you need, or would really even want, to run that as root, as 1) security, and 2) the files will be setup for use by the root user, not your user user. This is a guess, as I currently am not running a linux workstation so can't verify any of it.

Have you tried with Oracle java or OpenJDK, instead of the OpenJ9? If so post logs from that as well.
