Hi guys! My MacBook (Late 2008, aluminium) won't go to sleep immediately. I've been having this issue since I've updated from Lion to Mavericks a few weeks ago. Before the update the MB went to sleep within 2-3 sec. Now it takes between 20-30 seconds and it really annoys me I had a similar issue around half a year ago. Back then it was Google Chrome which prevented my Mac from falling asleep immediately. Apparently Google fixed that issue.

Any suggestions will be appreciated.
