<waves at Casey> I just ran into the same issue. My java control panel shows java 8, but that error message seems to indicate that it is trying to execute with a much earlier version of java. I'm not an OSX expert, but from what I can find with google it seems to be something esoteric about how the app is packaged that is making it use the wrong java vm. Might well also have to do with having upgraded from an earlier OSX.
There's probably a better way, but a workaround I found was to explicitly run the application from a terminal window with the JAVA_HOME set to the correct version of java. In my case, the java control panel says the correct java path is "/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/" and the AltOS app is installed in /Applications/AltosUI.app, so after some poking around: export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/ java -cp /Applications/AltosUI.app/Contents/Resources/Java/ -Xms512M -Xmx512M -Dosgi.clean=true -jar /Applications/AltosUI.app/Contents/Resources/Java/altosui.jar It still gives me some startup errors, I don't know if I would trust it to configure a flight computer and I haven't tried connecting to a TeleDongle or TeleBT, but it is at least functional enough to view and export a previously downloaded .eeprom file, which was what I was after. You can probably guess which .eeprom file I was interested in. Erik On Mon, Sep 3, 2018 at 6:49 PM Charles L Hakes <[email protected]> wrote: > That is what I was seeing.
