How to speed up Retina MacBook Pro wake from sleep
Last week while Mark Gurman and I were complaining about those little imperfections that mar the otherwise fantastic Retina MacBook Pro experience, Chad Coleman passed along a tip from Erv Walter on how to make the Retina MacBook Pro wake from sleep faster. This is for those times when you lift the lid, see the password entry field, but can't actually enter a password for what feels like 10 seconds or so. I mentioned it on MacBreak Weekly on Tuesday, and so many people found it helpful I figured I'd mention it here as well. From Ewal.net:
What is actually happening is that these new MacBook Pro’s (and recent MacBook Air’s) have a new powersaving mode which Apple calls standby. Standby mode kicks in after the laptop has been in normal sleep mode for about an hour. When that happens, the contents of RAM are written to the hard drive and the RAM is powered down to further extend battery life. In theory, the laptop will last up to 30 days in standby mode. The trade off is that, when waking up, it takes a long time to reload 16 GB of RAM from the hard drive (even with SSD).
It's a battery saving feature that, if you're plugged in, feels like a bug. If you're not on the road and you want speed over savings, Walter shows a terminal command that lets you change the standby delay. I've been using it all week and it's been great. I'll be traveling this week, however, so I'll be reverting to default. That's the nice thing about it -- you can set it to what makes the most sense for your current work flow.
