What steps will reproduce the problem?
1. Download Arduino.
2. Run Arduino from within the disk image.
3. Try to upload a sketch.

What is the expected output? What do you see instead?
The expected output is that the sketch should get uploaded to the board.  Instead, you get "Build 
folder disappeared or could not be written".  

There are a few possible solutions.  One is to simply provide a better error message.  Another is to 
improve the .dmg so that there's a shortcut to the applications folder and an arrow in a background 
image.  A third is to change the upload process to not use a sub-directory of the sketch folder/ for

Moved compilation during upload to the same temporary folder used during verify / compile.

I happen to often access the applet folder, looking for .elf and .hex files.
Now i can't easily access them, because the temp folder has a strange path on my osx machine.

Other people feel similar, have a look at this thread:

The attached patch is a suggestion on a  very simple fix: Make the temp folder accessible in the Sketch Menu:
* Compilation is still done in temp folder, so no regression regarding the .dmg issue
* Easy Access to the temp / compilation folder, where we can copy the .hex or .elf files from.
* No negative Effects for Beginners
Please consider this Patch for next Release of Arduino.

Best Regards,
