hello

i need download macintash for this imac please help me

Your question is so vague as to be unanswerable. You need to do two things and post the result:

1. Click the Apple icon at very top left of the screen, and choose 'About This Mac'. Below 'OSX' report the version it quotes.

2. Go to Applications/Utilities and open 'System Information'. Quote the 'Identifier' in the second line - it's something like 'iMac7,1'.
