Here’s a recipe for setting up Minecraft server on OS X. Since I don’t fully trust the server not to have some security hole, I want it to run as user nobody so it doesn’t have a lot of permissions. And I also want it to restart automatically when I reboot the computer. Finally I show how to backup the worlds you create. Lil beethoven sparks rar.
There’s three parts to this hint.
1) creating the launchDaemon that starts the minecraft server.
2) how to turn it on and off
3) maintaining backups
2) how to turn it on and off
3) maintaining backups
The first step is to download the minecraft server jar file from the Mojang website. Currently that site is https://minecraft.net/download but that might change in the future. And currently the jar filename is: minecraft_server.1.6.2.jar, but that will change too.
1) Creating a place for it. When you run the jar the first time it’s going to create a lot of files and subdirectories the in the current working directory (CWD) so we want to create a nice place to do this. It doesn’t matter where this it, but the permissions on the folder do matter. I put mine in /opt
Now if your user name is bob then move the minecraft jar into place:
and make sure the top level folder and executable are owned by root. This will assure that no one can change the jar file without root access. Since the system is going to invoke this file automatically you don’t want it changing with simple user level permissions.
Minecraft is going to run as user nobody, and it will need permission to modify the state folder contents.
2) Creating the launch daemon:
Hey guys, I am unable to upgrade my Mac OS. Currently it's version 10.8.5. Is there a way to make skype work for my macbook. Hacks welcome:).
I have a Palm Zire (m150) that I use all the time. I have upgraded my computer use from Mac OS 10.4.11 to OS 10.8. My Zire uses OS v 4.1. Is there an upgrade or software available that will allow me t read more. Feb 16, 2019 For what it’s worth, accessing the “About This Mac” screen from the Apple menu goes way back to old school Mac OS releases as well, so if you dig up an Apple Macintosh SE/30 from an attic you can find the system software version on those old Macs the same way too. If you’re running High Sierra (10.13), Sierra (10.12), or El Capitan (10.11), upgrade to macOS Catalina from the App Store. If you’re running Lion (10.7) or Mountain Lion (10.8), you will need to upgrade to El Capitan (10.11) first. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.
As root, create the file
The file name is not important, but it’s tradition to name the Daemon for website that it came from. You need to create this as root or otherwise assure it’s owned by root:wheel and can be read. It’s not an executable.
The above is plist speak to tell it that it should change into the working directory where we want it to store its data, then launch the java jar with a memory size of 1G. You can adjust the values for your system if that turns out to be too much. It also tells it to run the job as the username nobody. And it will start the server when the Daemon is loaded, which happens either at boot time or if you explicitly tell the daemon to load.
The key thing here is that the paths to the “state” folder and the executable are hardcoded. You must change these paths if you set this up in a different place.

If it’s not installed OSX will usually ask you if you want to install java and then automagically do this for you.
as root, (sudo -s -) run the following: launchctl load /Library/LaunchDaemons/net.minecraft.plist
test to see if it worked: Asap ferg trap lord zip sharebeast.
does the output include something like this:
If so then the server jar is running and is running as nobody.
If not then you made a mistake. To help diagnose this try running the command right from the command line. note, at this point you are running the server as root. This is reasonably safe, assuming you trust mojang, to do for a moment just to eliminate the permission issues. If you are nervous, disconnect your ethernet cable for a moment.
You may see some java exceptions printed in the process, but if the program stays running then it’s working. Once it stops printing stuff out, type ctrl-c to kill it. List the current directory (state) and you will see a whole bunch of files and folders have been created. So now you know the program and the paths are right. You’ll need to find the error you made. Most likely a permissions issue.
2) controlling it. to load the server by hand:
Foxyproxy standard for firefox. it will start when you load it the first time.
to stop the server temporarily
Here I used the name not the path. The name is one given in the plist file not the actual file name. Normally you want to make these the same for sanity sake. This command stops the server but it doesn’t remove the autostart Daemon—next boot it will start again.
to restart it after stopping:
to unload the daemon (so it won’t autostart at boot)

3) backing up the state. from time to time you may want to back up the state of your minecraft world and the server configuration (banned-IP, whitelist, config…)
To do that:
this command will create a snapshot backup of the state of your system. This will look like a copy off the state directory tree and files. But it’s not a copy. It’s a hardlinked image. It doesn’t actually occupy any (significant) disk space unless your world is changed. The command names the new snapshot for the date and time down to the hour.
You can restore an older image to being the current state by deleting the current state folder and moving the state folder from the image folder to the minecraft working directory.

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.
If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.
This example shows macOS Catalina version 10.15 build 19A583.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
