How can I wake my iMac up from sleep mode? Can I do it via iPad?
I've set the "Wake on Demand" in the system preference, but don't know the way to wake it up.

It wakes up automatically in response to requests for certain sharing services.

When my IMac awakes from sleep mode, the password login screen freezes and no cursor appears.

Hello! When my IMac awakens from sleep mode, my log in screen is frozen (I can't type anything) and there is no cursor.
I can turn the computer off and on again and then I have an active log in screen, but if I walk away from the computer and it goes into sleep mode and i have the same problem trying to bring it back from sleep mode.
Thoughts?

Hey Kristogirl,
I understand that when waking from sleep mode, your iMac freezes. Try executing these two troubleshooting steps:

Everytime I wake up my computer from Sleep Mode the sound starts to crackle on my X-Fi?

Sometimes I'll be playing a song and a few seconds in it starts to crackle and distort the music. I notice that it only happens after my computer wakes up from sleep mode. Usually restart can fix the problem.
I have an original X-

Okay, I seem to have solved the problem I posted about earlier. I noticed that the language preference in the upper right hand corner of the screen (between the date and time and the Spotlight icon) had somehow gotten switched from American English to French. When I switched it back to American English, my password worked when waking the computer from sleep mode. I have no idea why changing the language preference would affect the way the password works but that seems to have been the case. I'll post again if I experience more problems.

Can I wake my Macbook Pro from Sleep with the Remote app on the iPhone?

I can't access my Macbook Pro remotely, specially after several hours of inactivity,, whenever I try to access content of my library through the remote app or the Apple TV I'm unable to wake my Macbook Pro up.
My Macbook Pro is 2012 model (the last with de CD Drive) and it's running the Maverick OS, my questions are:
* I'm unable to find the "Unable Power Nap while plugged" option on the energy saver tab... is that because the model of my laptop doesn't support that?
* In order to access content from my library remotely, should the "Computer Sleep" option on the energy saver be on "Never" instead of the "1 hour" that I'm currently using... or is there a way to still be able to wake up the laptop with those settings

Do you have a Bonjour Sleep Proxy server on your network?

If you do not have a Bonjour Sleep Proxy server on your local network, then you cannot allow your Mac to go to sleep at all. System Preferences -> Energy Saver -> Computer Sleep -> Never (slide all the way to the right).

Can't wake my MacBook up from sleep after Mountain Lion update

I have a MacBook Pro spring 2011 model. I did purchase the Mountain Lion update in September and this is when my problem started. I do have the put hard drives to sleep when possible turned off. The only change I have made to the Mac is the ram, I upgraded to 8GB but haven't had any issues with it. Any suggestions on what to do? The hard restart or having to shut my Mac down everytime is a pain.

Ibook won't wake up or crashes after waking from sleep mode

I have now had this problem for the last year with my new ibook g4 and I can confirm that the problem is present at OS X version 10.3.0 - 10.3.9 and 10.4.0-10.4.5 . I'd manage to solve it but once in a while it shows up again and i have to solve it all over again. Apple doesn't seem to care although it makes your iBook totally unusable if you can't put it to sleep mode, because of the fact that you can't leave your iBook ON while the lid is closed. Ok as I said I have this problem once in a while but I allways manages to solve it, here are my observations:
Leting the computer go into sleep mode by itself (not by closing the lid) will not result in a crash.
Before a crash the following allways occour:
1) The system gets highly unstable. Programs (mostly safari, mail and itunes) will crash without warning. The mouse reacts very slowly and lags behind. The mouse lag is a shure indication that the system will crash during the next seconds or minuts.
2) While set to automaticly connect to favorite network, the airport won't connect imidiatly, but it will take a few seconds more than usual before it connects.
3) The system sometimes crashes before it can activate the backlight resulting in the situation where people think that the system can't wake up from sleep mode and won't react.
Only forcing the computer to sleep mode can cause this failure (by pressing "sleep mode" or by closing the lid).
What i did to rule out some sources resulting in this error:
1) Something like this problem can happen when having a bad memory socket or bad memory, so I'd ran Apples Hardware test and memtest OSX, but no failure was indicated.
2) Ran the usual repair of disk permissions (like 10^6 times ), without any changes.
3) Tried to reset the PMU (Power managing unit), without any changes.
4) Also tried to make a clean installation with panther 10.3 and tiger 10.4, without changes. Before installing anything (no prgrams or updates) the system still crashes. Even after updating to. 10.3.9 and 10.4.5 the problem is still present
The solution:
Well I found out that the problem has to do with to power options. That would normally mean that reseting the PMU would help, but as I already said this didn't change anything. Apparently the system is not able to wake up the Harddisk from sleep mode, and that's basicly the problem. I don't understand why it doesn't crash when going to sleep mode all by itself, but aparently there's something diffrent by forcing the system to sleep mode. Fourthermore it's not so "happy" to change those settings for the harddisk (I will explain later).
Solution:
1) Basicly just UNCHECK the option "Set harddisk to sleep mode whenever it's possible" inside powermanagment. And set "let the computer go to sleep after" to "Never" , do this for Battery and AC Power settings.
2) And put CPU usage to "Automatic", do this for Battery and AC Power settings
3) Restart the ibook. When it plays it's startup sound reset PVRAM by holding the following keys down before the backlight turns ON: OptionCommand+PR , when you hear the startup sound again release the buttons and start OSX normally.
Now as I said this problems comes once in a while and that has to do with the fact that repairing my disk permissions can change/reset the above changes. Even if it isn't beeing displayed graphicly repairing the disk permission have reseted those changes, resulting in the fact that the system is crashing again.
So to solve this do the following for Battery and AC power settings:
1) CHECK/MARK the "Set harddisk to sleep mode whenever it's possible" inside powermanagment and put CPU usage option the low or high. And set "let the computer go to sleep after" to "Never"
2) Restart the ibook.
3) UNCHECK the option "Set harddisk to sleep mode whenever it's possible" inside powermanagment". Put CPU usage option back to "Automatic". And set "let the computer go to sleep after" to "Never"
4) Restart the ibook again. When it plays it's startup sound reset PVRAM by holding the following keys down before the backlight turns ON: OptionCommand+PR , when you hear the startup sound again release the buttons and start OSX normally.
So now it doesn't crash again.
I've read all the threads of people having this problem and apparently it has been present since OSX 10.0.0 and when calling apple support they tell you to reset PMU and repair the usual disk permissions, which of cause doesn' work. And there are aparently a lot of really angree costumers, because this problem makes the computer COMPLETLY unusable, but apple has done nothing to help those people because of the the fact there there has been released ZERO patches or changes in OSX to resolve this issue. I can't say that there is something wrong with the iBooks as the several hardware test's indicate no malfunctioning but there is some bug in Mac OSX wich specificly makes the system incable to tell some ibook's how to wake the harddisk from sleep mode.
To the fine folks working on this forum: No I will not send this to apple, they already know about this, and have done nothing (just think of the millions of crash reports they recieve from those hundreds of crashes everybody is geting from this problem). That is why I put this on the forum so that people can actually solve this problem by themselves. If you think it's worth sending to apple, so that this problem can finally be fixed after 4-5 years you are more than welcome to send it directly to somebody who will actually do something about this. And i really hope that giving people the opportunity to make ther computer work, doesn't violated the usual rule "that we are not allowed to write anything that is agains apples interests", wich often results in a removal of threads and ANY chance in SOLVING critical errors.

sdad sdsdds:
Your observations and solution are right on the money!!
I just was working on an iBook that my father is giving to my sister. I must have started the problem by changing the sleep setting for battery to let HD sleep. After that the fun began! Instability, restart after restart, running Disk Warrior, fixing permissions over and over, etc. I finally zeroed out the HD and installed 10.4. Nothing worked until I read your post.
Thanks a lot. I understand how you feel about posting here, but please be aware that you are helping many people who would be completely without a clue otherwise. Thanks again for your efforts.
Now I can ship my sister her iBook!

Is there a way that iTunes can act as a Radio Alarm Clock? I have found the radio station I enjoy listening to in the iTunes Radio List. Is there anyway iTunes (and my Mac) can be set to come-on and start playing that Radio Station from Sleep mode at spec

Is there a way that iTunes can act as a Radio Alarm Clock?
I have found the radio station I enjoy listening to in the iTunes Radio List. Is there anyway iTunes (and my Mac) can be set to come-on from Sleep mode and start playing that Radio Station at specific times of the day?
Any App or plug-in that does that?
Many thanks
Kevin

Turning your Mac into a clock radio.
1. In iTunes create a playlist that contains just the radio station you want to wake up to.
2. Export the playlist (as .m3u works well). Get Info on your playlist file and look at the Open With entry to make sure it points to iTunes, VLC or some other app that will stream your station.
3. In iCal create an event entry at the time you want to wake up.
4. Right (or Control) click on your wakeup event and select Get Info.
5. For "alarm" select Open File.
6. Now under Open File there will be a place to add the file to open. It will probably be some default entry (like iCal). Click on it will allow you to select "other." Then use the file dialog to select your playlist file.
Your Mac will wake you up at the appointed time. You don't need to keep iCal running. If you want to put you Mac to sleep for the night then there is one more thing you need to do. Open System Preferences to Energy Saver and click on the Schedule button. Check Start up or wake and set the wake up time to slightly before your iCal alarm time.

Mac Pro will not wake up from sleep mode

Hi,
In my Energy Saver I have my system set to go to sleep after 15 minutes of not being used. Unfortuantely, when I try to wake the system up from sleep mode, it freezes on the screen saver and I have to hard restart the computer to get it to turn on again. I see that this is an issue with MacBook Pros, but I'm not seeing much in the Mac Pro Towers. I did see a thread about Parallels VM causing causing OSX to not wake up from hibernation mode, but I am not always running my VM Ware when the system decides to not wake up. Any help/advice is appreciated.
Thank you,
Julia

.... and you fail to mention the model SSD and firmware version... or how you installed or cloned the system
most people also move most of their user folder to another hard drive.
sounds like a more normal Mail + OS issue if just that.
hard restarts = directory corruption so don't reboot w/o first either Recovery Mode, then follow up with Safe Boot.
And maybe you have 3rd party hardware or software that is not compatible with 10.8.2 needs to be considered as well.

Macbook Pro (2012) won't wake up from sleep mode

Hi,
When I purchased the Macbook it came with Mountain Lion. It worked fine. Then I updated to Maverick and lots of problems happened. The most annoying one is the wake up thing. I was glad to update to Yosemite thinking that it would resolve my problems. Nope. It still wake up very slowly from sleep mode, sometimes not at all -- I have to shut it down.
I don't know what to do.
(BTW, I tried every trick suggested on the Apple support page: SMC, PRAM...)
Help !
Thank you

HT2954 How can I access my imac mail from a different computer other than Apple?

How can i access my imac email from a differnt computer other than
apple?

If you are using IMAP mail connection (IMAP keeps the mail on the server), then you just configure the other computer's mail client to access the same account.
If you are using a POP mail connection, then the mail is generally downloaded to your Mac and deleted from the server. That is a much more difficult problem to solve. NOTE: Google's gmail does have a POP option that does NOT delete the mail on the server, so it is accessible via the gmail web page.
A lot depends on what you are using for your mail service and whether you are using IMAP or POP protocols.

I can't wake my iMac from sleep

I upgraded my mid 2007 24" imac to Mavericks. After the upgrade after 10 min my screen goes black (sleep). I can't wake the system up. After a few mins it shuts off. Since then I tried several things to figure out was it mavericks or just timing of an issue. Since then I added a new hard drive, then added Mountain lion back on and replaced the memory from 4 gig to new 4 gig. I still get the same issue. After 5 - 10 min the imac goes to sleep mode and I can't awaken it. If I pull the plug out and plug back in I have about 5 - 10 min again before it goes black. It is out of apple warranty so any help I would appreciate. I would like to fix it and I can do it myself if I knew what it was. Power Supply?, Video Card? Logic Board? Any ideas or checks I can do? I am technical and I can disassemble and reasemble myself. Is there any *ram that could have gotten updated or corrupt while upgrading the first time to Mavericks???

Can't use mouse/keyboard/trackpad when waking iMac from sleep mode

Basically as the title says. When I wake my iMac from sleep mode I am unable to use my keyboard/trackpad/mouse during the login window. Once the screen goes black by itself, after a minute or so I can then log in properly.
Yes the keyboard/mouse/trackpad are all connected when it wakes from sleep as I can use any of them to wake it from sleep, I just can't move them or type with them in the login window.

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 on some models, 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 models. 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.

How do I stop my imac OSX from automatically opening itunes 10 when a new device is attached via USB.

How do I stop my imac OSX from automatically opening itunes 10 when a new device is attached via USB? The devices do not pop up in itunes under a sync category, so I can't turn them off one by one, nor would I want to.
I apologize if this has been answered, but I couldn't find the solution for this problem.

Thanks for the reply but it didn't solve the problem unfortunately and I didn't think it would as I only downloaded Firefox for the first time a few days ago even though I have had this problem for over six months using IE.
Anything else that you think is worth a shot?

IMac occasionally fails to wake from sleep mode

This is a transient problem. Happens every 2-3 days that computer fails to wake up from sleep mode. Space bar doesn't do anything and I finally have to unplug it and reboot. I have a late 2008 iMac and am running Lion. It has started doing this after I installed Lion but doesn't seem to be related.

It's tough to troubleshoot intermittent problems. You can try by restarting in Safe Mode, this will clear some caches. It's possible one or more is corrupt.

My imac freezes , need to restart everytime i wake it from sleep mode. just started happening 2 weeks ago.

For about 2 weeks whenever I return to my imac and tap the mouse to wake it from sleep mode my screen is frozen. I have tried to wait for it to unfreeze but it doesnt wake. I cannot get any results from using the mouse or the keyboard. I always have to hard reset the computer to be able to use computer again. My mac is a year old. Anyone have any thoughts as to why tis is happening? Thanks

If you have more than one user account, these instructions must be carried out as an 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.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.
