Here is a link to Modloader for MCb173. It needs adding directly into the minecraft.jar file, however if you use a launcher like MultiMC, which you can find here: https://multimc.org/ then there is an option to 'add to minecraft jar file' which does the same thing.

I used to have this issue lots, and it was due to my internet being too restrictive. The Minecraft Launcher was refusing to open, and I fixed it by messing with the restrictions until it worked. Hopefully this helps :) if all else fails of course, try just reinstalling it! I’m sure that all your config files don’t get affected by reinstalling it, but just in case make a backup. And if all ELSE ELSE fails, you could switch to a completely different launcher, like MultiMC! Good luck!

If you are willing to try out the launcher - MultiMC which you can find here (there is a Mac option available) : https://multimc.org/ then I have put together an MCb173 pack that has been made for MultiMC. You just use the 'import from zip' option.

Download MultiMC from their official site https://multimc.org/

Others than that, if you insist, you can take a look at the launcher which u/reginakinhi provided or find others on the internet (GitHub for example). Since PrismLauncher is written in C++, and if you are not familiar with it, you should see other launcher as well. Or else https://github.com/MultiMC/Launcher is an alternate.

The best way to experience beta 173 is to play beta 173, and perhaps add some mods to it a little later. One of the better launchers to use for old versions and for playing modded is to use the MultiMC launcher which you can find here: https://multimc.org/

This will only assist if you are using MultiMC as your Minecraft launcher as it is a MultiMC instance which you can use the 'import from zip' option. MultiMC can be found here: https://multimc.org/ It includes IC2 1337 with several add-on mods which have also been back-ported to work with it, such as the Thermometer, Advanced machines, etc. You can disable the add-ons you do not wish included. There is also buildcraft and redpower added as well.

I googled "fabric crashes with falling block" and found this GitHub Issue in the Sodium Repo. Solution: install Indium, because continuity relies on it to bridge over to sodium.

It`s Indium. https://github.com/CaffeineMC/sodium-fabric/issues/1324

if https://github.com/CaffeineMC/sodium-fabric/issues/1006 is what you are talking about, it is an upstream issue for any forge port of the sodium mod

Wow, a reasonable criticism! According to this issue, transparency sorting hasn’t been implemented, and so the behavior is inconsistent. Surprised to see a pull request linked that had fixed it, but was never merged and is now incompatible. Definitely affects users who have farms and stained glass builds though!

The problem with the multithreaded version of Optifine is that OpenGL doesn't officially support multithreading (at least not with older versions of OpenGL; Sodium (for modern versions) uses a "multidraw" function to get up to 10x the FPS but also uses OpenGL 4+, and even then it has issues on many drivers. Note that using such modern features would require a "core profile", precluding the use of all legacy fixed-function methods so the entire renderer would have to be rewritten).
