Recently (in the past month or 2) my Mac (2012 Macbook Pro 13 inch) will take at least a minute to 90 seconds to wake up from being asleep. It usually happens when it is asleep overnight and. When it's asleep for about 20 minutes to an hour, it only takes a few seconds to wake up (like I expect it to).
When I first bought my Mac about 7 months ago, it would wake up really quickly, which makes me think that I changed a setting somewhere.
What setting should I change to relieve this problem?
