Multiple Accounts - Minecraft

The fix I found was to look at the permissions of the Application. /Applications/Minecraft.app I noticed that they were Owner: R+W,Admin: RO, Everyone: RO. I initially changed this at the app level by doing a "Get Info" and changing them to all being R+W. This did not fix it. I then navigated to the app file and right-clicked and selected "Show Package Contents". Then selected the "Contents" Folder and right-clicked and selecting "Get Info". At this info page I unlocked(bottom right corner) and changed both admin and everyone to R+W. then I selected the gear (bottom middle) and selected "Apply to enclosed Items...". At the prompt click "OK". then the app opens in the other accounts.

App Level --> change R+W for all

Contents Level --> Change R+W for all and then apply to enclosed items.

I did this and it worked:

• Change the permission level for Minecarft app in your Applications folder to read+write for all users and everyone. Instructions:
  • Right click on file in Finder, then "Get Info" or Command+i on the file
  • Bottom right corner of the pop up window, click on the lock symbol and unlock to allow changes
  • Select read+write for every and all users
• Go to Finder
• Right mouse click on the Minecraft app in your Application folder
• Select "Show Package Content". All the content files and folders will be revealed
• Change the permission level for the following files to Read and Write the same way you did above.
  • Files to change Read Write on:
  • Content>Info.plist
  • Content>MacOS>Launcher
  • Content>MacOS>Minecraft updater.app
  • Content>Resources>favicons.icns

John, as of today, I have the exact same issue as you experienced. Although I did have Minecraft working on multiple user accounts on a MacBook Pro running 10.10.5 *before* updating to the new Mac launcher for Minecraft. After I updated to the new Minecraft launcher this morning, I started having this issue. I agree with your hunch that this is likely a bug in the new Minecraft launcher for Mac. Possible solutions:

1. Use the old Minecraft launcher. Available from Mojang as Minecraft_legacy.dmg. Requires the old Java 6 runtime environment, so this may not be a desirable solution.
2. Follow the advice I found at http://www.cgwerks.com/make-minecraft-work-mac-osx-yosemite-latest-java-8/ and use the Linux launcher, Minecraft.jar, on my Mac. This one requires Java 8. I have the JDK installed, not sure if this would work with just the JRE. This is the solution I'm using currently. On the MacBook Pro, I have two regular accounts for my wife and me, and two managed accounts for the kids. I put Minecraft.jar in /Users/Shared where the managed accounts can open it, and told the kids to use that to start Minecraft.
3. ? Maybe Mojang will fix this...? I found a Mojang-run Minecraft Launcher bug tracker with this same issue. The bug was submitted last week: https://bugs.mojang.com/browse/MCL-4011. I was too lazy to register for the Atlasssian account to pile on to this same bug... I wonder if more of us piling on to this bug would make a difference?

The root application should be installed in the Applications folder. If it's parked somewhere in a users folder that's likely the issue for trying to run under multiple accounts. If it is already in the applications folder it's possible the game is linked to the account you used when the purchase was made, but I don't know for sure. I do think you're going to get better traction on the Minecraft forum for this questions. - as far as OS X is concerned it's as you said "This *should* work." - but this assumes it should work the way you want and not the way the developers intended.

I had the same problem. For me, the problem was addressed when I installed the alternative launcher:

On the minecraft download page, in the section for Minecraft for Mac OS X, there is an

alternative download: Minecraft_legacy.dmg.

I deleted the old Minecraft from Applications, then installed from Minecraft_legacy.dmg.

(If you are using parental controls for appliances on your daughter's account, check those after the install).

After that, minecraft is working under all of our accounts.

I don't know what the underlying problem is, but this got my son playing again.

ESTABA Intentando descargar el Minecraft premium al que hace? UNOS meses habia borrado y Ahora no me deja ... no se Por Que, en solitario Pero me Aparecen los enlaces Como Si estuvieran Escritos, Haber si me explico, no Llevan un ningún lado, como no fueran enlaces. Aqui les pongo lo que me dice

--->

Descarga Minecraft.dmg.https://launcher.mojang.com/download/Minecraft.dmg

Minecraft para Mac OS X (alternativa)

Si está utilizando una versión anterior de Mac OS X y está teniendo problemas con la nueva descarga, puedes probar el viejo descargando Minecraft_legacy.dmg.http://launcher.mojang.com/download/Minecraft_legacy.dmg

I encountered this recently. What I discovered is that the .app is correctly installed in /Applications However the launcher and related data is installed to /Users/<user account used during the install>/Library/Application Support/minecraft Every other user that attempted to launch the .app would fail with the error the OP reported. Simply changing the .app and it's Contents folder to R+W for everyone did not solve my particular issue.

However, uninstalling and reinstalling using the "legacy" installer did. Just make sure to backup your ~/Library/Application Support/minecraft folder first in case you have mods and other data installed there.

This worked perfectly. Thanks so much.

Thanks . I was having the same problem and your fix worked perfectly !
