Ihope this makes it easier for other people to do. I had the hardest time wrestling with the new Minecraft launcher to get multiple versions of Forge up and running. Not that it was difficult, just that I didn't know how, and I couldn't find any good videos that just got to the point and did it. Why does it take a 20 minute video to talk about how to get multiple Forge instances in Minecraft launcher??
This is a really good tutorial (I agree tutorials of the multiple modloader installs, such as using 2 Forge versions from 1.12.2 and under or 1.13 and higher or some such as covering, 1 Forge, 1 Fabric, 1 Rift, 1 Liteloader or so even need to take 20 minutes, I've not seen many that do what your saying for 20 minutes, but if there is any out there are they just doing so for padding it out as there obviously isn't much to say for that long even as a mod spotlighter and trying to cover everything and waste as less time as possible I've never had that happen for tutorials).
Either way I don't think there is many tutorials covering what your doing using 1.13+ and 1.12.2 Forge when installing them into the Vanilla Launcher and how different they are, at least I haven't seen any yet, just how to install 1 Forge version.
For this server, and this server only (make changes to servers as desired), the java_binary will 100% replace whatever the default Java is. You should now be able to run multiple versions of java, i.e., have numerous versions in parallel downloaded at once, and use them at-will.
I have Java 16 running on MineOS and Java 8 and 11 as alterative versions, so this will allow me to down grade my java for lets says bungee which requires Java 11 to run right, and I have a server which need Java 8.
I am using Ubuntu Server to host multiple Minecraft servers. For the latest versions of Minecraft, I need the latest version of Java; however, I would like to run a modded server as well and some of the mods are incompatible with the newest version of Java. How can I run the modded server using Java version 15 while running the other servers using the newest version? I am fairly new to Ubuntu Server so any help would be much appreciated.
I'm trying to setup Minecraft for my daughters on their own OS X accounts of our new computer. At this point I'm using normal un-restricted accounts while I troubleshoot. Whatever account I "install" minecraft on it will work. But if I switch users and launch it then I get the error "Minecraft updater - Unable to start Minecraft, if you are running from a dmg, please drag to Applications and try again."
I am not running the DMG. I've installed it via drag and drop to the apps folder and then deleted the dmg etc. So it works on the users account that I install it but that error pops up on any other accounts that I try to open minecraft with later.
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.
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.
Ok, first off I installed it in the admin account originally and on my latest try. As far as "root". It's in the root applications folder but the "application support" folder for minecraft is in my admin user profile and not the root from what I can tell. When I get home maybe I'll try to move that folder and see if it helps. Though I'm not sure if that will confuse the app since it's likely looking in that specific location it was installed.
No, it's not. It was actually purchased on a different computer at my parents. It installed and worked on this computer ok but just for whatever account it's installed to directly. I can overwrite the install from another users profile on the system and then it works from that profile only.
The developers intend for this to work as far as I can tell. It just doesn't. I believe there must be a bug in their software or something. That link even proves this by mentioning how to set things up with multiple users and block each other from using each-others worlds etc.:)
I'm 70% sure it didn't auto generate those files for the new user accounts on our brand new system though. So that could be the problem. Maybe I can duplicate those files from the user account that works and paste them for one of the new users. Worth a shot...
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:
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 ningn lado, como no fueran enlaces. Aqui les pongo lo que me dice
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//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.
Are you familiar with bytebycode by Alex Xu ? You probably do, because it's the most popular Substack newsletter in the world, discussing topics and trends in large-scale system design by the creators of the bestselling System Design Interview book series. Personally, I'm a big fan, not even just because of the knowledge that is presented there (as it covers, however, mostly quite 'laboratory' architectural cases), but because of the format. The whole thing is very accessible and strongly visual, and as a result, even on topics I am fairly familiar with I like to take a look at what they have described. That's why when they published the text Evolution of Java Usage at Netflix I decided that this was the perfect opportunity to share ByteByteGo with you.
There have always been a lot of myths floating around about Netflix itself, as arguably in a formative period for many of us it was from their solutions such as RxJava, Nebula and Hystrix that we learned (including from mistakes) how to approach Microservices architecture, I myself remember my fascination with them somewhere around 2016. However, back in May 2022, Paul Bakker was explaining on Twitter that in fact RxJava was already, as I described in JVM Weekly #4 (but that time flies). Last year at the Spring One and Infoq conferences Paul talked about the evolution of not only the Netflix approach to Java, but also the architecture - you can see the presentation itself here:
Reverting to the publication of ByteByteGo, this one clearly builds on Paul's presentation, discussing the evolution of Netflix's approach to Java and demonstrating how the company's architecture has dynamically changed to meet growing technological and operational demands. Netflix continues to rely firmly on Java, but over the years, the Java stack at Netflix has undergone significant changes, moving away from a monolithic architecture towards a more decentralised and flexible microservices architecture. The article describes the shift from using Groovy scripting as part of the backend to frontend (BFF) pattern - I further remember the days when Netflix promoted its own Falcor solution - to the introduction of GraphQL Federation, a response to the need for more efficient query and data management. This change allowed for a significant reduction in API redundancy and redundant data retrieval, which is crucial when supporting a variety of customer end devices (and Netflix has a plethora of these end devices to handle).
Also, the article touches on the evolution of the Java version at Netflix, moving from Java 8 to newer versions like Java 17 and 21, which has contributed to better CPU utilisation and reduced operating costs - well worth it overall. The company has also standardised around Spring Boot, while leveraging the benefits of a broad open-source community. Overall if you like to make technology decisions based on what BigTechs show at conferences (not recommended) - the whole thing is really interesting. Even if you don't use the lessons in the text with common sense, the whole thing will show how such an evolution takes place in a large organisation.
