On my MacBook 1.1 with 1G of RAM and a 7200 RPM HDD using SafeSleepOnce • it only takes a few seconds to power off • roughly ten seconds to restore desktop from cold boot! • this is great because I can leave apps, docs etc open and still shut down and they'll be exactly as I left them when I turn the computer on again

This is an AppleScript. As such, it has its limitations and oddities. I have it running on macOS 10.12.6 Sierra. But it requires your Admin PW every time you use it, which gets annoying. Also, it's prone to going into Sit&Spin mode after you use it, requiring a Force Quit. For free, its OK, but quirky.

Press power button lightly to wake form sleep? ? Surely you're kidding. Press a bit too hard and you'll re-start. Yikes. Plus I got a message that USB devices have been disconnected because they're consuming too much power. Only happened since installing SafeSleepOnce. I;m on OS 10.10.5. Might be okay for some folks - certainly not for me.

I confirm, after a daily use for about one month I bet, that I'm a more than happy user of hibernate mode (and SafeSleepOnce ;-). I've discovered that hibernate mode is also very convenient as you can detach the power cord from the wall it will start just the same, combining in some way shut-down and sleep mode.

Working perfectly! And the ability to disable confirmation dialog in the prefs makes it a one click action (or a programmed shortcut). I launch it now instead of my usual shortcut for Shut-Down, so I still can access normal sleep and true shut-down when needed (via Apple menu or else). On my desktop computer it has 2 benefits: - never accidentally wakes up again - consumming less power than normal sleep (I'm ecologically concerned ;-) The longest wake-up time is not a problem for me. The allegations of people having problems are probably due to misconceptions or lack of patience! - First of all: the Hibernate mode is closer to Shut-Down mode than to Sleep! You won't wake your Mac up touching keyboard or mouse, you have to push the start button as in normal startup! - then your normal screen appears as blurred with a kind of progress bar, but this one seems blocked until it wakes up completely, so if you don't wait long enough, you may think it's crashed but it's not! - I believe that this and other utilities doing the same job are only GUIs for a normal Terminal command so it cannot crash or damage a sane computer For anyone interested, the Terminal commands are: - to check sleep mode : pmset -g | grep hibernatemode - to change it : sudo pmset -a hibernatemode x (where x=0, 1 or 2 ; normal sleep=0, hibernate=1) And a very important thing: check your available disk space before using!!! (in my case, the sleepimage file uses 4Gb, so I suppose it could be an issue if you don't have enough free space)

As mentioned there http://osxdaily.com/2010/10/11/sleepimage-mac/ The sleepimage file is generally the exact same size as the amount of physical RAM your Mac has. If your Mac has 2GB of RAM, the sleepimage file will also be 2GB because there are 2GB of data that need to be stored when your Mac is put to sleep. You can check the size of your sleepimage file by typing the following command into the Terminal: ls -lh /private/var/vm/sleepimage

Just for your information, in newer versions of OS X "hibernatemode" should be "0", "3" or "25" according to `man pmset`.

Computer never woke up.. it started to but remained stuck/frozen in the process, not sure why I tried this app. curiosity I guess. Had to "long-press-crash-it".. Maybe it works for some. In the trash for me.

Sorry that it didn't work for you. While Apple is shipping the safe sleep functionality, it's not officially supported. SafeSleepOnce is just a wrapper for the built-in functionality, a tool called "pmset". If your Mac freezes, it's either a hardware or software problem which is, unfortunately, out of my control. I know of a couple of cases where Macs were suddenly able to safe sleep after deleting the power settings, reinstalling OS X or even just updating OS X to a newer version.

@ Wildfox: How is this malware ? I have not actually tried it yet but I cannot find any other reviews of it on the internet. Can you please explain how this is malware? you gave it a 1/2 star review... why?

SafeSleepOnce is not malware and I've been inviting people for years to have a look at the source code. What I have trouble understanding is why you gave it 2.5 stars when you haven't actually tried it.

Works great and I can have it in my Dock for quick access. I was using the similar widget for the dashboard, but this is more convenient and it doesn't require an administrator password at all, which is awesome. Thanks for this handy utility!
