Minecraft launcher on Mac OS Sierra gets stuck on downloading any type of minecraft versions. I've tried redownloading the Mac OS completely and no luck. Also fresh start on all Minecraft files and it also doesn't work. This has happend before on older launchers for people on Mac os Sierra and older versions of mac OS but those have been resolved and Minecraft worked fine until the recent Minecraft launcher updates. I've had success using a third party launcher MultiMC and being able to launch any version of Minecraft just fine even including mods. Thanks for any tips
