Mevarick energy saver

Dear all,
I recently had my IT people do a clean install 10.9.4 on a new SSD drive in my MacPro 3.1. After realizing that it goes into sleep at night, I wanted to change the power management settings in "Energy Saver", however, all be hold, it is not in System Preferences. The com.apple.PowerManagement.plist file is there and I changed the setting using sudo pmset -a sleep 0 and pmset -a disksleep 0. I will see tonight if it goes to sleep. But anybody have any idea where did my Energy Saver tab go. Any help would be greatly appreciated.
Best,

Good point, I did not check that, but now that I did, no it is not there. Spotlight search also does not find it. Is it possible not install it in the fist place. My company has green energy requirements so they force all hardware to go to sleep. I wonder if they disabled it somehow. When I asked them about it they were not aware of such a practice, disabling Energy Saver, that is. Very strange to me.

UPS Energy Saver on MacBook Pro for External Drives

A search here has shown this topic come up before -- such as at https://discussions.apple.com/message/1886738#1886738 and https://discussions.apple.com/message/8162836#8162836 -- but I can't find a resolution, so I'm bringing it up again.
I have multiple FW drives connected to my MacBook Pro. The MBP is connected to an APC Back-UPS RS 1200. OSX does not make the UPS Energy Saver autoshutdown preferences available on the MBP, the reasoning being that a laptop shouldn't need UPS autoshutdown because it has its own battery which is likely to run for far longer than the UPS would.
That's all well and good for the MBP itself, but it doesn't account for the multiple FW drives which are attached to it for backups and other purposes. In the event of a power outage, without UPS autoshutdown, the UPS will run down, and the drives will abruptly power off, exposing them to potential data loss and damage.
It's also not a solution to suggest that I manually power things down once there's a power outage, because the power can go out while I'm away for more than the few minutes of UPS battery back up time. The only real solution is to have UPS autoshutdown available on all portable machines. Unless and until Apple offers a (surely very simple) OS update to make that happen, I'm still interested in a solution.
APC's own software for autoshutdown stopped being updated long ago, so there is no version compatible with Snow Leopard.
The only potential solution I've found so far is http://www.apcupsd.org/ -- but its documentation is overwhelming and it appears that it may need other supporting software, a fair amount of Terminal usage, etc., all making it not very user-friendly for the very simple usage I'd want to make of it.
Does anyone know of any other solutions, software that can run on a MBP to add UPS autoshutdown functionality?
Re: Apcups, is anyone using it successfully on a MBP? If so, does anyone know if the version listed here -- http://mac.softpedia.com/get/System-Utilities/Apcupsd.shtml -- is a simple application that I can easily install and configure like regular Mac apps? If yes, then I'll likely be very happy with no need for the following question. If no, can anyone provide simple instructions to set up Apcupsd to do what I want?

"You are not doing anything on the computer so no files should be writing to the drives."
Big assumption there. With today's notebooks so capable of acting as desktop substitutes, they are often left running unattended to complete demanding tasks overnight or while the user does other things.
To be able to suspend such activities and gracefully power down an external drive or drives in the event of a power outage, the Mac would have to have instructions from each third-party application or process that is running about how to interrupt its activity safely and without jeopardizing the integrity of whatever hard disk directories are in use. Then it would need to unmount the drive(s) and, if they were bus-powered drives, turn off the power to each of them at the port to which it was connected. I bet it would be possible for all app developers to write such instructions into their apps' code, but where's the incentive for them to do so? This isn't a feature that most users would gladly pay extra for, I suspect, and the cost of adding it to apps that don't have it now and testing it for reliability and proper function under all conceivable circumstances would not be trivial.
If the drive(s) were AC-powered, the computer wouldn't be able to power them down itself -- the UPS would have to do that, or simply leave them on and power them until its battery was depleted or the AC was restored. It wouldn't matter which happened as far as the drives and their contents were concerned, because once the computer stopped using them, powering them off would be safe at any time.

UPS and Energy Saver

Energy Saver keeps forgetting that I have a UPS (APC) connected. I have to unplug the USB and plug it back in for Power Adapter and UPS to return to the Energy Saver dialog.

below a certain percentage refers to the remaining percentage of battery life.
For example: If you set it to shutdown at 30%, then it will shutdown when the battery level drops below 30%.

Energy Saver on MacBook

I missing in Snow Leopard the pop-up menu with settings for Better Battery Life, Normal, Better Performance, or Custom.
And I can't find this options in Energy Saver System Preferences pane.
Why not? I need it!

I have no option to enable more drop down option for the battery menu bar icon. The bug may have to do with specific notebook models. I have the original MacBook Core Duo white.

My battery icon has disappeared from my menu bar at the top of the screen and the energy saver preferences simply says 'Could not load Energy Saver preference pane'

My battery icon randomly disappeared a few months ago from my menu bar and i have been unable to make it come back. After researching solutions online it soon became clear that all of the suggestions needed me to go into the energy saver preferences in the setting however the icon for the energy saver preferences is no longer there and whenever i click in the blank space where it used to be, it simply says 'Could not load Energy Saver preference pane'. As a result of this i never know how much battery i have left and so i just have to wait for the machine to die each time
The mac in question is a 13 inch 2012 macbook air that is running on OS Mavericks at the moment.
Any ideas on how to get the icon back?
- I recently discovered by accident that before i actually log into my account on my mac, when i am still on the page that contains the options of guest user etc. at that point the battery icon is displayed in the top right hand corner? Why is it that the icon exists there but not once i have logged it? Thankyou for any advice.

Hard drives sleep - not energy saver settings

I have two(2) different Quad 2.7 Pro Mac computers, both with 2 500GB Seagate drives mirror raided internally and Sonnet Fusion D500 SATA enclosures with 5 500GB seagates RAID striped.
They all fall asleep after inactivity, and it take several seconds for the drives to spin back up. The energy saver is set to never. I even tried turing it on, restarting, turing it off, reseting, but it did not help.
I've removed the internal RAID and the external still sleeps, and vice versa.
My only thought is it it the seagate drives. They are refurbished baracuda 7200.9 drives.
Any ideas?

hello,
i'm experiencing the same issue. i have 4 internal raptors in RAID0 and 4 external WD drives in a PM enclosure and have found that they too sleep as you mentioned.
i checked the energy saver and the box is unchecked to "put drives to sleep when possible" also...
i installed Leopard the other day when i got the new enclosure and external equipment - clean install - so i don't know if it would do the same in Tiger...
any suggestions, or is this normal for exterior storage - regardless if it is SATA or not?

Mac Sleep Timer (through 'Energy Saver' in System Preferences) won't work

Hello,
I have a MacBook (13-inch, Mid 2009) running Mac OS X Snow Leopard 10.6.3,
and it has been installed with the latest software updates possible.
(The latest update is the 'Security Update 2010-003')
Previously I was using Mac OS X Leopard 10.5 on my MacBook,
and I can vaguely remember the timed computer sleep through Energy Saver would work.
That is, when the counter's time matches the amount of time I specified (e.g. 10 minutes), the computer enters sleep mode and displays a pulsing power light.
After upgrading to Snow Leopard I can barely remember the scheduled computer sleep will work as I don't really notice how it sleeps / I will shut down my MacBook before I go to bed.
==========
However, last night I was really tired and slept in front of my MacBook unconsciously.
When I woke up, I found that my MacBook didn't display a pulsing power light but a continuously-growing power light.
I tapped the trackpad and the display turned on, so I knew that my MacBook didn't go to sleep a whole night.
*What that means is that the Sleep Timer (through 'Energy Saver' in System Preferences) won't work.*
But the timed display sleep DOES work.
==========
After spending a whole day Googling,
I found that there are plenty of people suffering the same problem as me, although their Macs and OSs vary.
I also found an official support page from Apple concerning the related issue:
Mac OS X: Why your Mac might not sleep or stay in sleep mode
http://support.apple.com/kb/HT1776
I tried the following methods but still can't resolve the problem:
_- boot my MacBook in safe mode_
_- use the 'Disk Utility' to repair Disk Permissions through booting my MacBook from the Mac OS X Snow Leopard Installation DVD_
_- reset NVRAM (Intel-based) (as PRAM is used by PowerPC-based Macs)_
_- reset SMC (System Management Controller)_
NONE of the above-mentioned methods can resolve the problem.
Althought I am sure that the Spotlight isn't indexing the hard drive, and I just start my computer and do nothing and wait for the scheduled computer sleep, the scheduled computer sleep just won't work.
In the other Mac forum, I saw someone suggest installing an application called PleaseSleep:
http://www.dragonone.com/products/macosx/pleasesleep/
It works.
But I really want to find out what caused this problem as this is a function shipped with Mac which is expected to work normally.
What's more, Apple is claiming to be a green Apple, right?

Looking forward to your replies! Thanks in advance!

Found this discussion by googling "com.apple.systempreferencescouldn't find any matches"...
One month ago I bought a brand new Macbook Pro 13", and after a couple of weeks I realized it wasn't sleeping on its own when it should, per the system preferences. (I did sleep when I chose "Sleep" in the menus or closed it... It just wouldn't sleep on its own, while open.) What was extra frustrating was that it was intermittent... It would sleep on its own maybe 1/3 of the time, but other times it would NEVER go to sleep. I deleted PowerManagement.plist, reset the SMC, etc... No luck.
I took it to the "geniuses" at the Apple Store, and the guy took all of five minutes trying to diagnose the problem. When my MBP wouldn't sleep on its own, he promptly replaced it with a new one. That was nice, but I actually would have preferred that he diagnosed and fixed it. (I think the store was so swamped with people coming in for service that day that they were doing anything they could to close cases and get customers out of there ASAP.)
Now, sitting here with my 48-hour-old MBP, I still have the problem. The other one was so new that I had barely put anything on it yet. The only applications I had put on it were MS Office for Mac 2011, Firefox, Chrome, and Adobe Flash Player. I've put Office and Flash Player on this one, but not yet Firefox or Chrome. That's it. No other customization or fancy business.
I looked into the Console just now, and I see the "Couldn'tfind any matches" entry popping up again and again. The last three seemed to pop upright around the time when my MBP should have gone to sleep on its own, but not down to the second, so it's hard to definitively point at that and say it's it for sure.
They need to fix this!!

New iMac 24" Grey - Energy Saver Issue

10.4.10
2.4Ghz Intel Core 2 Duo
1GB 667 Mhz DD2 SDRAM
Boot Rom 1M71.007A.B00
Model Ident: iMac7,1
*The Energy Saver is having issues*
Put the Computer to sleep when it is inactive for - set to Never
Put the display to sleep when it is inactive for - set to Never
Unchecked - Put the hard disk(s) to sleep when possible
The reason I have the above set the way I have it is cause I'm running some performance tests... however, every 2-3 minutes the Screen is turned off, the Hard drive is turned off and the computer is put to sleep. It's doing exactly the opposite of what I want it to do. Which then in turns puts a massive hit on the performance results every time the computer goes to sleep.... even though it's told not to go to sleep, I'll even click the lock to lock it down but that doesn't matter, it still goes to sleep 2-3 minutes later.... AND it doesn't matter if the mouse moves to keep it active.
Is there a Fix for this?
I ran the software update and it doesn't do much. But in the end it still does the same thing.
I've reinstalled the OS several times but that doesn't fix the issue.
Again to reiterate,
Energy Saver window in the System Preferences
Sleep Tab
both sliders set to Never and Hard Drive is set to NOT go to sleep (as it's unchecked)
I have other iMacs some older some the same, all work as told, except this one.

Yep, that seems to agree with your Energy Saver preference settings. It would be surprising only if they did not match . It appears that the GUI and pmset are working with the same preference file (as they should).
*sleep = 0* <----------> Put the Computer to sleep when it is inactive for - set to Never
*displaysleep = 0* <----> Put the display to sleep when it is inactive for - set to Never
*disksleep = 0* <-------> Unchecked - Put the hard disk(s) to sleep when possible
OTOH, I would have expected see one additional line: "*halfdim =* \[0 or 1\]" -- controlled by:
*Energy Saver > Options > "Automaticaly reduce the brightness ...yada, yada"*
I'm also running 10.4.10 (but on a white C2D). When I set my preferences to match yours, pmset -g always lists "halfdim = 0" or "halfdim = 1", as expected. Kinda strange that yours doesn't list it.
I presume you've followed den.thed's good advice on resetting the SMC, so the only things I can think of would be:
\- Make sure Screen Saver is set to 'Never' ... but I'm guessin' you already did that
\- Delete the Energy Saver preferences and scheduled events files (make copies first!), then immediately shutdown and reset the SMC ...yet again!
Here's where the Energy Saver preference and schedule files live (from "man pmset"):
+All changes made through pmset are saved in a persistent preferences file (per-system, not per-user ) at+
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
+Scheduled power on/off events are stored separately in+
/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
+pmset modifies the same file that System Preferences Energy Saver modifies.+
I wonder if the EFI ROM is old, and needs updated.
I don't think there have been any EFI updates for the 2.4 GHz iMacs -- but I'm sure someone here could confirm/correct that.
...who knows what evil lurks in the mind of pmset?

Please Help: Cannot open Energy Saver on iBook

When I click on the Energy Saver preference pane on my iBook (dual USB) G3 (running OS 10.3.9, with a 20 GB hard drive with 13 GB of space left), I get the message "Preferences Error, Could not load Energy Saver." This just suddenly started happening a couple of days ago.
I have searched this forum as well as Google and have found no information about this problem. After I opened Disk Utility while booted from my external hard drive, I ran First Aid and Repair Permissions on the iBook. No change in the problem with Energy Saver.
Here are the additional steps I've taken:
1. As a test, I created a new user account and logged in under that account. Still got the same message when trying to open Energy Saver.
2. I attached my iBook to my iMac G5 via firewire cable and booted my iBook into target disk mode. Then I ran Disk Warrior and TechTool Pro on the iBook. Both programs gave the iBook a clean bill of health.
3. Via the Find command, I searched my hard drive for any files with "energy" in the title. No hits.
4. I went to my ~/Library/Preferences Folder and found the com.apple.systempreferences.plist file. Removed that file, restarted the iBook. Still could not access Energy Saver.
5. I put the System Preferences application into a folder called Sys Prefs Old. Dragged the System Preferences application from my iMac into the Applications folder on my iBook. Opened this new System Preferences application. Clicked on Energy Saver pane. Still got the message "Could not load energy saver."
6. Inserted OS X 10.3 install disc into iBook. Used Pacifist to re-install just the System Preferences application. The application was an older version than the one that had been giving me problems. Opened this application and clicked on Energy Saver pane. Still got the message "Could not load energy saver."
I'm at my wit's end. I can no longer change any of my energy settings on my iBook. If anyone can make a suggestion, I would certainly appreciate it. If your suggestion has to do with using Terminal, please talk me through it in baby talk because I've never used Terminal.

It may help to look in your log files to find out why your applications are quitting.
The simplest way to look at log files is to use Console.
Open the Console application from /Applications/Utilities. It will default to showing the "console.log" and possibly the "system.log". Use the File menu if necessary to get both these logs open, and use the Broom to Clear both windows.
Now try to open the Energy Saver preference pane and see what appears in either of these windows. Copy and paste it here.
You may see a message saying "Crash report written to <pathname of crash.log>". Click on the "Logs" icon at the top left in the tool bar. Then, depending on the <pathname of crash.log> in your message, look under either ~/Library/Logs or /Library/Logs by clicking the disclosure triangle, then click the disclosure triangle for "CrashReporter".
Find the crash log corresponding to your message and select it. It will open at the end of the log. Look back for the last line of asterisks in the log, then post everything after that to the end of the log.

My AppleTv keeps dimming as if it is in energy saver mode. My DVD player and TV do not do this. How do I disable the energy saver feature on AppleTv? BTW this is my second AppleTV device so it does not appear to be a product defect.

My AppleTV keeps dimming as if it is in energy saving mode. My TV and DVD/Netflix player do not do this. How do I disable the energy saver feature in AppleTV? BTW: This is my second AppleTV device so it does not appear to be a product defect.

I keep seeing versions of this same question, and it's always the same answer: it's the TV. Well, it happens to me as well. But it only happens when viewing programming via Apple TV. My cable is totally fine: no dimming. Only with Apple TV. So what's the answer?

How do I save changes to "Energy Saver" that stay in effect after rebooting.

I have changed the sleep settings for the hard disk and display for my iMac but after I shut down and the start up again, the settings are back to the default settings. How can I save these changes and avoid having to do this change every time I boot up?
Tim

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Set the Energy Saver preferences the way you want them.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Check the settings while in safe mode. Have they been reverted? If so, set them again. After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Automatically change energy saver

Is there anyway that I can have energy saver automatically change the setting to "Highest" when I start up Halo? I noticed a huge performance leap when I changed to highest in the middle of playing halo and was wondering if there were an easier way to change the settings.

Sort of, yes. For 99% of the users and applications, it works pretty good. However for demanding applications and games (like Photoshop or in this case, Halo) Apple recommends that you use the "Highest" setting to get optimal performance:
From the developer docs :
http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G5/iMacG5May05/iMacG5.pdf
Note: For best performance when using professional applications with high demand on the system
(such as Final Cut Pro or Logic), you may want to set the processor/bus speed option to highest.
Games are really hit or miss, regarding performance. A lot of modern games offload much of the heavy lifting to the GPU. In many cases, the load on the CPU is not constant so the Automatic setting throttles everything back. However there is a "lag" time in between, so it's not an instant change back and forth from Automatic to Highest. So in order to get the most even, constant performance, Highest is recommended.

Will Not Sleep In Energy Saver Mode

My iMac G5 20" 1.8Ghz will not sleep when I set it to sleep in the energy saver panel. This just started for no specific reason a few months ago. It will sleep fine when selected from the Apple menu. I have been through the discussions and no one seems to have a good fix for this. I have repaired permissions, reset the PRAM and SMU, and tried all the different configurations in energy saver. I called AppleCare and they seemed not to know anything about this issue. They recommened an archive and reinstall of the operating system. I feel this is kind of drastic for this and I have not yet tried it unless I can see that other people have done it and it works. My computer is in the repair program for the power supply problem and it has an updated power supply since the original actually smoked and Apple replaced it. I was wondering if anyone out there has had this same sleep issue and got it resolved?

Well I finally decided to try and delete an application that I suspected could be a problem not allowing my computer to sleep automatically. That application is LAST FM a music service from the UK which is actually quite good. I suspected it was a problem since it would always launch when I opened iTunes and asked if I wanted to share my iTunes library with the LAST FM group which I did not. I selected I did not want to share in the LAST FM preferences but it still opened anyway when I launched iTunes. I deleted the program and repaired disk permissions and *It Worked*, my computer will now go to sleep with the settings I selected in energy saver. I know there are other people out there with this problem I would first look at this application and others that are probably running in the backround causing your computer not to sleep automatically. I am a firm believer in trying to work up from the easiest solution before taking the drastic approach, such as a system reinstall, or a logic board replacement. I did take Nikki's suggestion seriously. My power supply had been replaced in the repair program and my logic board did not meet the criteria for replacement since it was not exibiting the symptoms that required its replacement such as video and power problems.

How to set "Energy Saver"- Setting for Power Adapter or Battery?

Under the System preference, how do I need to set the Energy Saver? There are options of Power Adapter or Battery for the Setting for. What is difference?

Here's how I have my energy saver settings set, first, click 'show details':
Power adaptor (when plugged into a power outlet):
Under Sleep: Put the computer to sleep: never (I close the display when I want to put it to sleep)
Put display to sleep: 5 minutes
Put the hard disk to sleep whenever possible is checked.
Under options, reduce brightness before sleep and show battery status on menu bar are checked.
Processor Performance: Automatic
Battery (when disconnected from a power outlet)
Under Sleep: Put the computer to sleep: never (I close the display when I want to put it to sleep)
Put display to sleep: 3 minutes
Put the hard disk to sleep whenever possible is checked.
Under options, reduce brightness of this display when using this power source, reduce the brightness before sleep, and show battery status on menu bar are checked.
Processor Performance: Reduced

FileVault 2 vs. Energy Saver – System Hang

I have an SSD primary drive and a secondary drive mounted in the CD bay of my MacBook Pro. Both drives are encrypted with FileVault 2. If I use the Energy Saver setting to "Put hard disks to sleep when possible", very often when I wake my computer from sleep, it hangs trying to access the secondary drive (where I have my iTunes and iPhoto libraries), and I am forced to reboot.
This seems like a pretty egregious bug in FileVault. It seems it must discard the key for the secondary drive when it sleeps? And does not prompt me to re-unlock the drive before it tries to acccess it. This seems to lock up my entire system.
It seems the only solution is to keep the drive spinning? Not so good for preserving battery life!

It's not a bug. Your hardware configuration is unsupported.
