Help Setup with mac

Post by sevenhillsreefer »

I keep getting "Uncaught exception in main method: java.lang.UnsupportedClassVersionError: Bad version number in .class file" any help would be greatly appreciated. Followed the instructions and deleted everything and tried it again with the same problem. Thanks in advance.

I followed the directions straight out of the manual. Downloaded the RA installer. dragged the wifi and anduino to applications. installed ftdiusbserialdriver and reset. Powered up the controller connected the usb my computer and to the RA controller all the way to the right with the two pins exposed to the left like shown in the manual. Im at a loss let me know if anything comes to mind. Thanks in advance, Brian

I get the error message when I try to open anduino. The error message pops up and then just gives me the option to quit. Is there any way to check to make sure the USB software is working? maybe it is not working due to not seeing the RA. Thanks in advance, Brian

That's PPC, right? Prior to Lion?
I haven't tested it on that version to be honest.
Can you download the original release from Arduino?

If it works, we will work around the differences.

PPC= PowerPC processor.
Mac used to have their own processor before they shifted to using Intel processor.
I think you need at least Lion, which I think is 10.6

I ordered snow leopard (10.6) Hopefully it will work after the upgrade. will keep you guys posted. I tried turning the Java on with same error. I am assuming the 10.6 will solve the problems hopefully.

I can confirm that snow leopard works. I have a mac mini running 10.6.8 and I just went through the installation exactly like you said it it worked just fine for me. Downloaded the installer, installed arduino and wifi utility, installed the ftdi drivers, restarted computer, launched arduino and it works. I even tried having it plugged into my controller while launching arduino and it still works.

I have tested it on Lion, haven't installed it on Mountain Lion yet.
