|
+MacOS cloud renting has started to proliferate with the new Apple Silicon M1 chip and it turned out to be a pretty decent way to test graphical applications on MacOS without buying apple's pricey hardware or resorting to hackish ports and vms of questionable legality.
|
|
|
|
|
+
|
|
|
|
|
+I am reporting here the procedure to quickly get a MacOS M1 cloud service up and running for testing jmonkey applications without too much hassle.
|
|
|
|
|
+
|
|
|
|
|
+This guide focus on Apple Silicon M1 instances, but can be replicated on x86_64
|
|
|
|
|
+
|
|
|
|
|
+### 1. Finding the right cloud provider
|
|
|
|
|
+Firstly you are going to need to find a place where you can rent your cloud server.
|
|
|
|
|
+We are going to need ssh, root and vnc access.
|
|
|
|
|
+I've been using https://www.scaleway.com/en/hello-m1/ with success. It is located in Paris, so people outside europe might want to find a local provider that has lower latency.
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+### 2. Install NoMachine Client
|
|
|
|
|
+These instances usually come with VNC enabled by default. However I've found VNC performances to be pretty bad, especially for realtime applications, so we are going to replace it with a much better alternative called [NoMachine](https://nomachine.com) that has nearly-local performances (tested on a 100Mb connection) and sound support.
|
|
|
|
|
+
|
|
|
|
|
+So for start you are going to need to install the client (that we will use later) in your local machine, you can use one of the following links:
|
|
|
|
|
+- [NoMachine (community edition)](https://www.nomachine.com/download) : Client+Server single app
|
|
|
|
|
+- [NoMachine Enterprise Client](https://www.nomachine.com/product&p=NoMachine%20Enterprise%20Client): Client only
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+### 3. Spawn an instance and get access credentials
|
|
|
|
|
+
|
|
|
|
|
+Now we can start with the server: spawn a new instance on the provider you've found before and then collect the following access infos:
|
|
|
|
|
+- instance ip
|
|
|
|
|
+- username
|
|
|
|
|
+- password
|
|
|
|
|
+
|
|
|
|
|
+If you rented from Scaleway, you can get all those infos from the instance dashboard that should look something like this
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+Note: VNCPassword is also the user account password and the ssh user **m1** is also the user account name
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+### 4. Ssh into the newly created instance
|
|
|
|
|
+If you are on linux chances are that you have already an ssh client installed, so you can just call
|
|
|
|
|
+`ssh [email protected]`
|
|
|
|
|
+from the command line.
|
|
|
|
|
+On windows you can use something like PuTTY, if you have never done that before you can follow this guide: https://tomjorge.me/how-do-i-connect-to-my-scaleway-cloud-instance-via-windows/ (it's the same for other providers).

|
|
+
|
|
|
|
|
+### 5. Install the required software on the server instance
|
|
|
|
|
+To have a working jme dev environment we are going to need the following software:
|
|
|
|
|
+- **Homebrew Package Manager** : It will make software installation easier
|
|
|
|
|
+- **Java11**: Java <= 8 has issues on mac
|
|
|
|
|
+- **Visual Studio Code with java extensions**: lightweight editor (this is my editor of choice, but you can use your favorite one)
|
|
|
|
|
+- **NoMachine**: Remote access server
|
|
|
|
|
+
|
|
|
|
|
+The following script does all that for you.
|
|
|
|
|
+- *Note*: you will be asked to input the password you got in point 3
|
|
|
|
|
+- *Note2*: There is an issue with audio driver installation in MacOS 12 and NoMachine 7.7.4, the script applies a workaround, if your instance doesn't have the affected software you can disable the workaround by commenting the `IS_MACOS12="1"` line.
|
|
|
|
|
+- *Note3*: if your instance is x86_64: comment the Apple Silicon JAVA_URL and uncomment the x86_64 url

|
|
|
|
|

|
|
|
+if [ "$IS_MACOS12" = "1" ];
|
|
|
|
|
+then
|
|
|
|
|
+ sudo rm -rf /Library/Extensions/nxaudio.kext /Library/Audio/Plug-Ins/HAL/NMAudio.driver /Library/Audio/Plug-Ins/HAL/NMAudioMic.driver
|
|
|
|
|
+ sudo mkdir -p /Library/Audio/Plug-Ins/HAL/
|
|
|
|
|
+
|
|
|
|
|
+ sudo cp -a /Applications/NoMachine.app/Contents/Frameworks/bin/drivers/NMAudio.driver /Library/Audio/Plug-Ins/HAL/NMAudio.driver
|
|
|
|
|
+ sudo cp -a /Applications/NoMachine.app/Contents/Frameworks/bin/drivers/NMAudioMic.driver /Library/Audio/Plug-Ins/HAL/NMAudioMic.driver
|
|
|
|

|
|
|

|

|
|
|
|
|
+ sudo launchctl stop com.apple.audio.coreaudiod
|
|
|
|
|
+ sudo launchctl start com.apple.audio.coreaudiod
|
|
|
|
|
+fi
|

|
|
|
|
|
+
|
|
|
|
|
+# Restart everything
|
|
|
|
|
+sudo reboot
|
|
|
|
|
+```
|
|
|
|
|
+
|
|
|
|
|
+### 6. Grant the permissions
|
|
|
|
|
+Now we need to grant the required permissions to NoMachine Server (nxnode).
|
|
|
|
|
+This is the most annoying part, since it cannot be done from the command line but it has to be done manually from the UI with VNC.
|
|
|
|
|
+
|
|
|
|
|
+So, log into your instance with VNC. If you are familiar with VNC, you'll know what to do, if not, this is the relevant tutorial [ How to connect to a Mac mini M1 | Scaleway](https://www.scaleway.com/en/docs/compute/apple-silicon/how-to/connect-to-mac-mini-m1/) .
|
|
|
|
|
+For convenience here a list of VNC clients:
|
|
|
|
|
+- [TightVNC](https://www.tightvnc.com/): Windows/Linux
|
|
|
|
|
+- [KRDC](https://apps.kde.org/krdc/): Linux+kde (this is the client i've been using while writing this guide)
|
|
|
|
|
+- [Remmina](https://remmina.org/): Linux
|
|
|
|
|
+- [RealVNC](https://www.realvnc.com) : Windows/Linux
|
|
|
|
|
+
|
|
|
|
|
+Once you are logged into MacOS, you need to go in Menu -> System preferences
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+From there you need to go in **Security & Privacy** -> **Privacy**
|
|
|
|
|
+Click the lock icon and input the password.
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+Now you need to enable the following permissions:
|
|
|
|
|
+
|
|
|
|
|
+- Accessibility
|
|
|
|
|
+- Full Disk Access
|
|
|
|
|
+- Microphone
|
|
|
|
|
+- Screen Recording
|
|
|
|
|
+
|
|
|
|
|
+*Note: Some permissions might not be recorded immediately, you might need to attempt to connect with NoMachine client once before they appear in Security&Privacy.*
|
|
|
|
|
+
|
|
|
|
|
+See images below:
|
|
|
|
|

|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+
|
|
|
|
|
+### 7. Done
|
|
|
|
|
+Now you are good to go, you can close VNC, connect directly with NoMachine and start your development and testing.
|
|
|
|
|
+If you use Visual Studio Code as editor, you will need to open it and install the [java extension pack](https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack).
