got-your-back VS Launcher

Got your back is the right tool https://github.com/GAM-team/got-your-back/wiki

alternatively, give them access to the user account and have them use Got Your Back ( https://github.com/GAM-team/got-your-back )

This tool from the creator of GAM will allow you to purge a mailbox: https://github.com/GAM-team/got-your-back

THe information it gives is inaccurate and it can sometime just stop. never had a good experience with it. for a couple accounts I'd go for GYB - https://github.com/GAM-team/got-your-back

GYB - gmail backup tool (I use the linux version, but it does have a version for mac).

if you don't want to spend you can also get only emails with "got your back". https://github.com/GAM-team/got-your-back

Either Google Takeout for everything, or GYB (got-your-back) https://github.com/GAM-team/got-your-back for email. You can try GAMADV-XTD3, but it can be super complex and I’m not sure if a standard account can use it or if you have to be super admin.

If you cannot - https://github.com/MultiMC/Launcher/wiki/Unsupported-Intel-GPUs

MultiMC

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.
