Not that i know what it is but would like to fix it anyway!
My Console shows this...but to my knowledge my MBA 10.8.4 is working fine ?

* WARNING: -[NSImage compositeToPoint:fromRect:operation:] is deprecated in MacOSX 10.8 and later.
Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead.
Honestly, I had to Google the word deprecated first to know what it means.
Deprecation is a status applied to a computer software feature, characteristic, or practice indicating it should be avoided, typically because of being superseded.
OK, so how do I fix that problem.
