Build folder error

Hello

i have a problem. Everytime i try to upload a code to my arduino mega says it: build folder disappeared or could not be written.

What Can i do?

I run mac os x snow leopard :)

Check that you have write permission to the folders and that there is not a folder higher up that is down as read only. Check and change this with the info box.

Where is the info box?

Hi light the icon by clicking on it.
Choose “Get Info” from the file menu of the finder.

How long have you had a Mac?

I have checked the info box, but it is still not working

Ka---ka,

I saw your post. I have just started with Arduino and have the same problem you had: "Build folder disappeared..." error.

How did you get around this?

Many thanks.

Did you drag the Arduino.app out of the disk image (into, say, /Applications)?
