I honestly have very little knowledge about computers or tModLoader, and could really use a lot of help. I tried installing tModLoader today and colossally messed up, almost destroying my vanilla game permanently. I was lucky to get it back and still don't know what I did or didn't do right.
I'm on a MacBook Air with Mojave, and downloaded tModLoaderInstaller from the link on these forums. After following the instructions on where to put files, I downloaded Java to use tModLoaderInstaller. I got an error when trying to use Java, the description of which I forget, but basically it said it couldn't access the file. So, I tried to install it manually using the ReadMe. I followed all the instructions up to the point where it told me "You need to give execute permissions to 2 files. Open a terminal in the install directory and run the following 2 commands:
chmod +x tModLoaderServer
chmod +x Terraria"
I have no idea how to open Terminal in the "install directory," since I am not sure where or what that is. After gaining no information on this, even through searching on these forums, Reddit, etc., I gave up and had to delete the tModLoader files to get Terraria working properly. I clearly deleted some of the wrong ones as it wasn't working, and finally I added a couple files back which apparently made Terraria open and run properly again. I have no idea which file or files that I added back made this work again.
Not really sure how anyone here can help, but basically I'd love advice on what to do about the Java error or, alternatively, how to execute the step in the ReadMe that I quoted above. Also, what do I do with the original Terraria file and other related files to make sure that (a) they aren't overwritten, (b) I can tell they're not a part of tModLoader and (c) I don't delete them? Sorry that I'm so dumb, I just really want to play Terraria with mods and can't figure anything out.
