Downloading files not possible

Hi there,

I just got a the new iMac 24" and unfortunately I am not able to download any file. I tried the safe mode and also the "Apply to enclosed items" trick, but none of these worked. Even changing the download location to many different folders did not solve the problem...

The message I receive is "Safari could not download the file “XYZ” because the disk doesn’t have enough free space. Try deleting documents or downloading to another disk."

And yes, I have enough storage ;)

I would be more than grateful if anyone had an idea on how to solve this issue.

Thanks!
