I’m getting this error:

(mxj add dir) unable to init mxj classloader. ERROR: -50

and can’t use any mxj objects.

It started happening with Max 6.0.0, and is still happening after an upgrade to 6.0.8

Any advice? Below is my whole Max window.

Thanks!

John

The uncommented lines are:

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

Thanks!

John

OS X updates have a tendency to remove it.

Terminal tells me:

Then perhaps try renaming your Max6 folder, installing a fresh one – does it work now?
