ComputerCraft mod not actually installed in Minecraft?

I'm a long-time Minecraft user, but I started over clean yesterday in order to diagnose the problem.

Yesterday: Downloaded and installed Minecraft version 1.8.8.

Downloaded the latest forge installer and ran it to install it.

Started Minecraft and selected the Forge profile. It downloaded all sorts of stuff. The start screen now shows Minecraft 1.8, MCP v9.10, FML v8.0.99.99, Minecraft Forge 11.14.3.1450.

Quit without starting a new game.

Copied the ComputerCraftPluseComputerCraftEdu1.74.jar file into the mods folder.

Restarted Minecraft with the Forge profile, release 1.8-Forge11.14.3.1450.

The splash screen now has the hammer & anvil and other new things when it's booting.

The Mod List shows Minecraft Coder Pack, Forge Mod Loader, and Minecraft Forge.

Started Singleplayer and created a new world using Creative mode.

Pressed E to get to inventory. It shows only the standard graphical menu of Minecraft blocks with 6 tabs across the top (5 + 1) and 6 tabs on the bottom, none of which are the ComputerCraft blocks, and there's no arrow to view additional tabs. I tried searching for a block called 'turtle' but it showed nothing. I don't know if there's a problem with my install or if I'm doing something wrong, but in the transcript below there's this message:

FML has found a non-mod file ComputerCraftPlusComputerCraftEdu1.74.jar in your mods directory.

I suspect that's telling me something important, but I don't know what it is.

The entire game output transcript is here:

ComputerCraft 1.74 is for Minecraft 1.7.10, not 1.8.x. You will need to install the correct Minecraft version in order to play with ComputerCraft.

At the moment, there isn't a version of ComputerCraft for MC 1.8

Some people have pointed out that the next version of CC will likely be for 1.9, since that'll likely be released in the next few months.

Ok, got it. I've downloaded 1.7.10 from here https://mcversions.net/ but I'm not sure what to do with the jar file. I'm on a Mac.

Does it go into my ~/Libraries/App support/minecraft/versions folder? I already tried using 1.7.10 from within Minecraft and I have the 1.7.10 folder &amp; files there already. (But of course, choosing 1.7.10 from within minecraft un-chooses the Forge 1.8 version, so that's a bit confusing.)

A) Installed Minecraft version 1.7.10.
Deleted all 1.8* versions.
Started Minecraft launcher, selected Forge profile.
Click Play, it downloads Minecraft version 1.8.8 and starts the game. This is not version 1.7.10.

B ) Started Minecraft launcher, selected Forge profile.
Disabled wi-fi.
Click Play, it attempts to download version 1.8 and fails, and does not start at all.

Any help would be greatly appreciated.

[Edit: changed "B)/>" to "B )" ]

Go to http://files.minecraftforge.net/ and download the correct (.jar) installer and run it.

It doesn't matter what the launcher says, it matters which version of forge you installed.

When you download the installer from the link H4x0rz posted, make sure to choose one for MC 1.7.10

Great, that worked! Thanks for your help.

It turns out that the www.computercraft.info/download/ web page is rather misleading. What I learned is:

* The web page incorrectly says you must use version 1.7.10 of Minecraft, but that's not true. You may use the latest version.
* The web page incorrectly says you must get the latest (up to date) version of Forge, but that's not true. You must use version 1.7.10.

Download and installing

The current version of ComputerCraft is 1.74. It requires version 1.7.10 of Minecraft, and an up to date version of Minecraft Forge.

Download ComputerCraft 1.74 (for Minecraft 1.7.10)

I'm not sure what you find misleading…

The current version of ComputerCraft does require MC 1.7.10 - it doesn't work in the 'latest' version.

As for Forge - "up to date" doesn't mean "latest"

When you launch Forge for 1.7.10, the version of MineCraft that starts is 1.7.10.

You're not limited to one single installation, see. At this stage you should have both 1.7.10 and 1.8 set up on your system.

Ah, yes. What I think I meant to say is that you may install the latest version of Minecraft to start with.

Thanks for all your help!

> The current version of ComputerCraft does require MC 1.7.10 - it doesn't work in the 'latest' version.

Yeah, I get that now. The thing is, Minecraft 1.7.10 is listed under the "Download and installing" section of the web page, so I assumed that it was something that I had to (get this) download and install. So I wasted some time trying to figure out how to do that.

> As for Forge - "up to date" doesn't mean "latest"

If "up to date" doesn't mean "latest", then what does it mean?

From https://en.wiktionary.org/wiki/up-to-date, "current; recent; the latest"
Or from http://www.merriam-webster.com/dictionary/up-to-date: "including the latest information; based on or using the newest information, methods, etc."

If you were told to go to web page X and get an up to date version of the software found there, which version would you get?

I'm just saying that the ComputerCraft download page could probably be re-worded to save people some trouble.

Well, the page tells you to get an "up-to-date" version of forge for MC 1.7.10. "up-to-date" means the *latest* release for your desired MC version.

Downloading updates (so it's "up-to-date") for an Win XP PC doesn't automatically make it a Win 10 PC, does it?
