Can't create/write to file .../-Tmp-/#sql137_2_0.MYI' (E:13)

[bismarck_vp]

Hi a changed the permissions to the folder ''/var/folders/lY/lYQllsNcG14Uigiyw-sCoE+++TI/-Tmp-/' and everybody could write/read, but when I restart my mac, the error means: "#1 - Can't create/write to file '/var/folders/lY/lYQllsNcG14Uigiyw-sCoE+++TI/-Tmp-/#sql137_2_0.MYI' (Errcode: 13)", I need some help, because XAMPP (specially .../phpmyadmin/ and "Section Manager" of .../administrator/) doesn't work well and I need it.

I'm sorry, I don't speak english.
