Scheduling wake up from sleep - how-to? and best time for cron and backup?

Background (or you can skip straight to question below): We use Retrospect to backup a number of machines over a network. We usually log the machines off and let the screens go to sleep however I'd prefer to log them out and then let the whole machine go to sleep and have them wake up for cron maintenance and backup.
One problem is I can't get Retrospect to wake the machines up, even if I have "Wake up for Ethernet network adminstrator access" checked in the Energy Saver Preference Pane, so I've scheduled the machines (under the Energy Saver Preference Pane) to "Start up or wake up" Every Day just before the backup starts (11:30 pm). (Note: the "Weekdays" option doesn't seem to work under 10.4.3).
So here's my question: what's a better time to have them wake up with regard to cron maintenance (considering they're currently set to go to sleep after 1 1/2 hours, which I'd rather make 1/2 an hour), and does it make any difference if I run the backup before, during or after cron maintenance?

Hello again Christiaan,
IMO, do not take this nightly automatic maintenance into account as it should not, and does not, influence your work and habits.
--> Since 10.4.2 the nightly tasks run automatically anyway (delayed), even if your computer was asleep at the default scheduled times. A very good enhancement, that would be perfect if only we could leave our computers ALWAYS on without restarting ever.
Still no automation if shut down at night neither.
Your question:
In Panther the answer is simple: Wake up at 3:10AM and back to sleep at 5:40AM (because the default maintenance times are 3:15am every day (daily task), 4:30am on Saturdays (weekly task), and 5:30am on the first day of each month (monthly task)).
In Tiger, the default times are the same (except the weekly task at 3:15 instead of 4:30), but they get delayed by the amount of time you slept your computer since the last reboot,
so,
--> you can never know when the maintenance will run, unless your computer NEVER sleeps.
Not a problem, because it is designed to run in the background, while your computer works (with Retrospect for example).
Just run this maintenance yourself manually once a month to make sure it's done. Once or twice a month is enough.
Use one of the "cache-cleaning" utilities or paste this command in Terminal:
sudo periodic daily weekly monthly
Post back if you have more questions.
Good luck!

Remote wakes iMac from sleep: how to prevent?

Hi all,
My computer plays music when I go to sleep, and I use the remote that came with my iMac to adjust levels, skip songs, etc. often, and it always wakes my monitor from sleep. Is there any way to prevent this? I'd like the monitor to stay off, it's so bright!
Thanks,
Alec

There are programs like this that dim the overall screen beyond the Mac's usual settings. So the screen may come on when you use the remote, but it will be much dimmer than usual.

I haven't installed any new software. I don't have the Samsung Magic SSD software mentioned in other posts, and the only devices configured to wake the laptop are the mouse and keyboard, neither of which is touched when the laptop wakes up. Any suggestions
on how this can be delayed until I wake up the laptop would make my wife very happy. I do have a scheduled task to wake the laptop to run the AV software while I'm away, but that's hours after it's actually waking up. Thanks!

try to go to Control Panel\All Control Panel Items\Administrative Tools
Disable and set the trigger as never at task scheduler > time sync
You can also try to clean boot

My macbook wakes up from sleep by itself all the time.

When the lid is open and it´s been inactive for some time it wakes up and then goes off by itself according to my settings in power and battery.
Also when I close the lid it doesn´t stop trying it makes noise over and over again.
All my settings are ok I think.
Does anyone have the same problem?

I don't understand how anything plugged into the same power outlet can have any impact on Mac Pro? This is so weird.
Like most Macs of the past 10 years, you don't turn it on with a mechanical switch. You turn it on with an electronic switch. When the machine is "off," it isn't really off. It's waiting for the proper electrical signal to begin the startup sequence. My theory is that if you happen to have something on the electrical circuit that generates a pulse that resembles the power-on signal that the Mac is expecting, it wakes up.
More commonly, it happens when there is a defective keyboard or mouse cable (causing a short circuit that wakes the Mac, as if a key or mouse button had been pressed), but more rarely it comes in through the electrical system.

MBP will not wake up from Sleep

Hi,
I installed Leopard successfully on Friday, and since then, my computer does not wake up from sleep about 50% of the time.
When I open the lid to attempt to wake it up, I hear the normal CD drive clicking sound (not the best way to describe the sound, but I don't know how else haha), but the screen just remains black. I cannot tell however, if it is a) waking up and the screen is remaining black or b) not waking up at all. The only way to remedy this is to hard to a hard shut down with the power button and then to power back on.
Anybody else experience this or know what could be causing this? I never had this problem with Tiger in the 5 months that I had it on my MBP.
Thanks for the help!

Just installed Leopard on my original 15" MacBook Pro 2.16 GHz Intel Core Duo. Last night, I had several applications open (Safari, Transmit, Timbuktu Pro) set up in separate Spaces. I closed the lid to put the machine to sleep. The sleep light was pulsing normally.
This morning, when I opened the MBP, the screen came on ok showing the last Safari page I was on and the Airport Indicator showed that it re-connected to my wifi as normal. However, the cursor was scrambled (the was a vague set of dots but no arrow where the cursor should be). This "scrambled cursor" moved around the screen when I moved my finger on the trackpad but the computer did not respond to any mouse clicks or keyboard input. I tried commandoptionQ to force quit but no luck. Eventually I had to press & hold the power button to force a restart & the computer then started up normally.

Short flickering when the notebook wakes up from sleep mode MacBook Pro Late 2013

Hello everyone!
I have a question concerning the display of my new MacBook Pro with retina display (late 2013).
Sometimes when opening the lid when the notebook wakes up from sleep mode, the display is flickering for like two seconds. Then everything is normal again.
This specially occurs when the lid has been closed for a longer time. It makes no difference if the power adapter is plugged in or not.
Have you experienced a similar flickering with your MacBook Pro?
Thank you in advance!

Hello!
I have the same problem with my late 2012 MacBook Pro Retina. The constant flickering after being awoken from sleep was a minor annoyance for me so I contacted Apple Support.
I shall explain what I have done thus far, and I recommend you follow the same steps as I did to tick off possible causes:
Firstly, I reset my PRAM (http://support.apple.com/kb/ph14222) and SMC (ttp://support.apple.com/kb/ht3964).
The issue still remained so I checked if the flickering occurred in a new user (if it does not then it points to your account having a setting which is causing the flickering - possibly third party). For me the flickering continued so I tested it in Safe Boot (which worked fine!).
I then ran (just to be certain) the Apple Hardware Test (http://support.apple.com/kb/ht1509). All seemed to be OK. So I reinstalled OS X and still the issue remained.
It was then I had an Apple Support person 'screen share' with me and we went through certain folders. My GPU folder had an unusual amount of files so we trashed them and began a restart however this led to a bigger problem; my notebook wouldn't boot (not even in Safe Boot!), so be very weary at this stage, I'm not sure if this was a rare case or we deleted something we shouldn't have. I then had to go into recovery mode to get back to square one.
Back to the initial problem I reinstalled a 'clean' OS X version from recovery mode; this was to determine whether if the data is corrupted on my account or if it's something else; most likely hardware by now even if there was nothing that came up in the hardware test (it won't account for everything). I checked from both a backup of my data and then from a fresh user after reinstalling OS X and still the flickering continued.
It was then a Senior Apple Support person set up an appointment to have my MacBook looked at and possibly repaired (it could be a minor wire causing the problem).
That is the point I am at now, so for my case it seems like a minor hardware problem. If your case is as similar as mine I recommend making an appointment with them to run more sophisticated hardware tests that your own MacBook would not run.
I will comment again when my issue is completely resolved for those who come across this Discussion in the future.
Hope this helps!

MacBook wont wake up from sleep, shuts down randomly, and won't burn. . .

Ever since I upgraded my MacBook to Mac OS X Leopard 10.5.4 from Tiger (and also purchased and installed Office Mac 2008), it will not wake up from sleep. If I close it while it is still awake, (which I normally would without problems before I upgraded) it will not wake up when I open it; the screen just stays black and I have to use the power button to restart it. This also happens when it falls asleep naturally after being on screen saver. It is a really big annoyance and I know that it must be damaging my computer.
Also, now it will randomly shut down if it does not have the power adapter plugged in, which never happened before.
ALSO, my CD burn attempts will fail midway and say "medium write error".
Can my computer not handle all of the new software I put on it or something? I feel as though it's slowly deteriorating, and it's not even 2 years old. Do I need to buy more memory or disk space? I am really clueless as to how to fix these problems. I'm only 16 and really can't afford to spend money on getting it looked at, so PLEASE help

Welcome to Apple Discussions:
You need to give us more info about your computer: RAM, speed, HD size, freespace etc.
Look at the activity monitor and console logs for potential issues.
Normally a computer will run faster and better with Leopard.
You need to take inventory of any Tiger apps that are not Leopard compatible that may be problematic. Also check what items you have in your login pane.
Have you recently run the disk utility and repaired HD and permissions?

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

I think I have the same problem. The whole sequence is:
* Put MacBook Pro to sleep by closing lid.
* After some period of time that varies, I notice sleep LED is no longer pulsing.
* The case is VERY hot.
* When I open the lid, the display stays black.
* No sequence of keys or closing/opening lid wakes display.
* Only way to recover is to power cycle.
* Problem is VERY intermittant -- I do not know how to reproduce it at will. AppleCare service had it for a whole week and couldn't reproduce it, whereas for me it occurs once every 1 or 2 days.
Actions:
* AppleCare service replaced the main logic board in early June, but it didn't help.
* I did a clean erase and install, but it didn't help.
* AppleCare service had the unit for a full week in July and couldn't reproduce the problem, so they returned it and it still had the problem.
I have a Logitech Bluetooth mouse, don't know model other than M-RBB93. I'll UNset "Allow Bluetooth to wake..." and will also turn off the bluetooth mouse before closing lid. I'll post my results.
Meanwhile, please let me know if anyone determines a solution!

How to take a photo after wake up from sleep

There are two questions:
how to create an automator to take a photo by isight in silent mode.
How to run this automator during the machine wake up from sleep.
Thanks a lot.

How do you make iAlertU take a photo and email it to you whenever the computer wakes up? I only know how to use it when you "arm" it as an alarm, which can get annoying to do all the time. I just looked in their preferences and I don't think you can set it to email you a photo whenever it wakes up without being in alarm mode.

Macbook under a year old keeps freezing and often won't wake up from sleep

So in the past week or so my 2012 Macbook has been having a lot of hiccups. I started noticing it wouldn't wake up from sleep and I'd have to just power it down. Then one day I was listening to streaming music and it started skipping and the screen froze and I had to power it down. I updated all my software, ran disk utility and scrapped a bunch of huge files yeterday, but today the screen froze twice and I had to power it down. I bought my machine back in July, I'm really bummed and hoping it's nothing serious this early on. Anyone have further trouble-shooting suggestions?

Ran what from DU?
and scrapped a bunch of huge files yeterday, but today the screen froze twice and I had to power it down. How large is you HD and how much space do you have left?
You have your standard 1 year warranty unless you also purchased AppleCare which gives you an additional 2 years of coverage plus FREE phone support.
Strongly suggest that you take FULL advantage of the above before it runs out. Let Apple deal w/the problems.

TS1367 I am asking this question about my 27 inch iMac Desktop Computer. I normally use my Laptop and very seldom use the desktop but was going to download the new software earlier today. I could not wake it from sleep.

The other evening we had a storm and lightening hit a house a few doors from me. It jolted my chair but that seemed to be all here. I use my laptop most of the time but since there was a software download I went to my 27 inch iMac and could not wake it from sleep. The light on the keyboard is not lit either. I have this connected to a Battery Backup Power so do not know what has happened or what to do. When I push the power button to try to turn it on nothing happens. There is no shound, no video, nothing; however the disk drive that does my time maching backup has a light on it and the other things that are plugged into the battery power pack also have lights on them. The printer is on and says it is ready to print. Since I cannot boot it up I do not know what to do to even try to get it started. I did not know what would happen if I put the first start up disk in the external disk drive and try that or not. The internal drive is broken. I do not have any repair shops or apple stores around me at all less than 150 miles away and I am disabled with 24/7 help and oxygen so can not take it in. Are there any suggestions that anyone can give me. I have not been able to find any way to reset the backup battery pack either. It is a Tripp-Lite. Any help anyone can give will be greatly appreciated. Thanking you in advance for your time and trouble.

OSX 10.7.5 How can I make my computer wake up from sleep?

My computer won't wake up from sleep whether I put it to sleep by a hot corner or by closing the lid. Has anyone a solution, plezase?

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, by a peripheral device, or by corruption of certain system caches.
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 and Wi-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. Test while in safe mode. Same problem? 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.

MacBook screen goes gray and won't wake up from sleep - 10.6.2

We have a MacBook Alum running 10.6.2 with 4gb ram.
We recently upgraded to 10.6.2 from Leopard and this issue started to happen.
It seems that as the MacBook goes to sleep or goes to the screensaver mode, the screen goes gray and won't wake up from sleep or screensaver mode without a hard reboot.
Is Apple aware of this issue? It did not happen with the previous version of Leopard. This issue arrived when we upgraded to Snow Leopard. Other than the sleep issue, SL is rock solid. Kudos to Apple for producing a great OS!

Hi GrooveDaddy,
Have you contacted AppleCare via telephone to make them aware of this issue? It definitely doesn't sound like normal behavior. What sort of troubleshooting have you done so far on the issue? What sort of settings do you have on your screen saver? Password protected? Custom iPhoto slideshow?
What if you manually sleep the machine by closing the lid or engaging it via software (via the Apple menu) does the screen have the issue in both scenarios?

It won't wake up from sleep after I open it. If I close it and then open it, it doesn't wake up for at least 5 minutes.

just upgrade my macbook air to yosemite. now when i physically close the computer and open it back up, it won't wake up from sleep mode. I tried pressing the power button, but it wouldnt turn on. Then once it somehow turned on by itself, I tried a PRAM and SMC reset. Then I tried closing and opening the computer again and I still had the same problem. nothing has worked. when i do get the computer on, i randomly goes into sleep mode again. I've check the settings for display and it says after 45 minutes of nothing it will sleep.

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully (some of it is hidden by disclosure triangles) and don't skip any of the steps, including the ones under the heading "Additional troubleshooting." If you don't understand any of the steps, ask for guidance.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
           ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
          Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
           ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
Step 5
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
