Scratch my question…
I had changed java Preferences to 32 Bit mode.
Should have changed Arduino to 32 bit mode.

Sorry to bother you…

Arduino ran find 2 weeks ago. I expect that I may have had a Java upgrade (but no sure). Now I get the message
“cannot launch Java application
Uncaught exception in main method:
java.lang.UnsatisfiedLinkError: /Users/
chadpennebaker/Desktop/arduino & iPhone/Arduino
16.app/Contents/Resources/Java/librxtxSerial.jnilib:
no suitable image found. Did find: /Users/
chadpennebalker/Desktop/arduino & iPhone/Arduino
16.app/Contents/Resources/Java/librxtxSerial.jnilib:
no matching architecture in universal wrapper”

I have set Java Preferences to ‘Open in 32 Bit Mode’; however, I still have the same problem.

Just had the same problem with version 15 and the fix worked a treat. Thanks.

Kyle,

thanks for the tip… saved a lot of troubleshooting and guess work

Here is a way to carry out the tip:

find java preferences under Applications/Utilities/Java…

found I had a similar version listing as Kyle

in terminal I descended the arduino directories to find the Info.plist, from the directory containing your arduino folder you can cd as follows:

cd arduino-0012/Arduino 12.app/Contents/

I used the pico editor to edit and save the file Info.plist, changing the following line which is near the end of file (see below)

pico Info.plist

1.4+

1.5*

(note 1.5+ didn’t work, had to be 1.5*)

and it now works

–last about 15 lines of edited Info.plist file, only change was to 2nd line you see here—

JVMVersion
1.5*
MainClass
processing.app.Base
Properties

apple.laf.useScreenMenuBar
true
arduino.app-resources
$APP_PACKAGE/Contents/Resources
