I am attempting to get basic mxj working on my computer running, and I am hitting the following issues.

I attempt to create an object [mxj net.local]

This prints the following to the max window:

/Applications/Max5/Cycling '74/java/lib/jitter.jar

/Applications/Max5/Cycling '74/java/lib/jode-1.1.2-pre-embedded.jar

/Applications/Max5/Cycling '74/java/lib/max.jar

/Applications/Max5/Cycling '74/java/classes/

In console.log, the following errors show up:

[0x0-0x351351].com.cycling74.MaxMSP[5877]    Java for ppc cannot run in this configuration.

[0x0-0x351351].com.cycling74.MaxMSP[5877]    Please consult documentation.

I am on snow leopard 10.4.6 with the developer tools installed, and I have followed the directions here: 

http://chxor.chxo.com/post/183013153/installing-java-1-5-on-snow-leopard

 to install java version 1.5. I have also deleted the max prefs folder. I am running version 5.1.4 of max.

This prints the following to the max window:

let's run a small test. Open you terminal(/Utilities/terminal.app) and type the next command:

using the java preferences to switch between them with the same result in each case. I also tried using both the 64 bit and 32 bit, with no different result.

I just installed snow leopard and i have the same problem : "Unable to create JVM" in max window.

By typing "java -version" in the terminal i get :

please note no one replied, and as the problem was on a clients machine, I wasn't able to resolve it myself

I have Snow Leopard 10.6.3, Max 5.1.5, and no problems with Java.

Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025)

Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)

But in the mxj quickie compiler window, the path to the compiler points to 1.5.0. So I'm assuming that my Max/MSP uses java 1.5.

In Cycling'74/java/max.java.config.txt you can specify which java version should be used by Max/MSP if you have multiple versions installed. Add this line to force java 1.6 (note that I haven't set this option on my system, but it fixed java problems on some Windows installs before):

And in the same file, there are some jvm options that are uncommented on my system. I don't know what they do (memory limits maybe), but it might be worth comparing:

@jonbro: Judging from the error mentioning 'ppc', it seems that you have a PPC version of java on your system (probably other versions too) and Max/MSP is trying to use that one.

java -version gives:
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)

; specify some jvm options ;
max.jvm.option -Xincgc
max.jvm.option -Xms64m
max.jvm.option -Xmx256m

Thanks for your message. In fact, just after reinstalling max latest version, it works. I don't know what was that, maybe I suspect some Ruby.jar that i'm not using and didn't put back in java max folder.

Me i put "max.jvm.option -Xmx1024m" instead of 256Mo to have more memory for java. it works fine with 1024Mo.

About jvm options :
Me i put "max.jvm.option -Xmx1024m" instead of 256Mo to have more memory for java. it works fine with 1024Mo.


"Java for ppc cannot run in this configuration."

Snow Leopard is 10.6 and doesn't run on PPC.
