Why does the mac take 60-90 seconds to wake up

sleep-wake

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?

Best Answer

  • As soon as it wakes up next time, examine the file /var/log/system.log (open a terminal and type less /var/log/system.log; Or open the Console app and find Files/system.log).
  • Scroll to the bottom (the most recent entries) and find the time at which you just woke the machine, scrolling up if necessary. The entries from there to the bottom should give a clue as to what was going on during the wake-up period.

You can also look through previous wake-ups the same way, to look at what was happening during the long delay.
