You should be able to run the ATLauncher .jar on 10.6 to play 1.12.2 in online mode. What issues are you running into?

damn it didn't post my reply. so i was using the app but then as you mentioned the jar file i still run into troubles. it says that it cannot open it so i opened the console and i got this. idk if i'm doing it wrong i just double click the jar file because i have no idea how to run the jar file in other ways.

EDIT: it did post my reply sorry abt that, for some reason it wasn't showing my previous reply lol

for some reason it's not posting my replies, i tried to check the java version and it shows up like this, not sure what does it means, but still tried launching the .jar atlauncher but no luck, the log says the same thing in the terminal, i'll try to search any possible fix

I'm also having this same issue on SL, if I somehow work it out (and remember to post it) I will post it here
edit: got it working, not sure exactly how, but I reran the installer (I forgot that there is that command at the end of the installer that needed to work, I was googling how to set a java as the default, which was wrong or something) I did also reboot after the install as well but that's all I have, ATLauncher though is being annoying though as it insists that it isn't alone in its folder despite me putting it in its own folder, meaning all data (login, instances, settings, etc) get erased every time I launch it (also I had to do it from the terminal too)

I do and it can play 1.21. I’ll get to releasing it once I finish the new build system.
 
MultiMC works, tested (OS X 10.9.5) on a MacBookPro11,3 with 16 GB RAM.
Tends to get anywhere from 80 to 100 without OptiFine (on default settings, except VSync is off)
with OptiFine it gets around 200 fps consistantly (on default settings, except VSync is off)
:D

How did you manage to log in? Did you use another computer, and transfer it over?
 
Yes, I did. I had to transfer the accounts.json file from a Windows Vista laptop, which was already logged in to MultiMC. If you transfer correctly, it should work. I *did* have some trouble using the same accounts.json on a Mac Mini running OS X 10.8 (launch OS) so OS X 10.8 and before *may* not be able to connect to Microsoft servers correctly.
