IMac takes a while to fall asleep.

when I'm ready to walk away from my iMac I either use a hot cornet to start the screen saver and password protect it (screen lock) or I go apple (menu) sleep (password protecting it as well).
I have noticed that recently it takes longer and longer for it to fall asleep.
when I click apple sleep the screen goes black but the screen light is on (I figure it's not gonna fall asleep in < 2 secconds, I don't either) and the fans keep going... and I figure 3 secconds is reasonable.
but it's been taking 10+ secconds.
also wake up time is slow too.
should I try clear my cash? tempfiles? or get a defrag program?
thanks in advance.

I think lots of people will help you get rid of any annoying cash you have!

Seriously, do you have anything that might be running in the background that the system is waiting for or gracefully suspending? Maybe a few external drives that need their buffers cleared first? Things that were not an issue the first times you used the system but may have been introduced. I don't think your Cache is the problem though.

20 seconds to fall asleep

Sorry to post yet another MBP sleep question.
Mine takes approximately 20 seconds to go to sleep each time.
I've tried all of the suggestions. Stopped apps, bluetooth, menu extras, etc.
I've also "pmset -a hibernatemode 0 lidwake 0" and I've renamed /var/vm/sleepimage, just to ensure it's not going into safe sleep mode. Cretainly does feel like safe sleep, although the waking is normal.
I discovered all of this because when I closed my lid it wasn't sleeping, and then when I opened the lid, it would sleep...
Anyway, I would like to get it to sleep in a few seconds instead of 20.

Are you saying that it takes about 20 seconds to fall asleep when you close it or click "sleep" from the Apple menu, or do you mean it falls asleep after 20 seconds of inactivity? I assume you mean the former. I'm pretty sure it takes a little while to fall asleep because the RAM is being paged out to the hard drive, which takes a little while. Supposedly, this is why people can swap batteries while their MBPs are asleep without having to restart them.
If that's what is going on, I don't think there's anything you can do to speed the process up. I guess you could remove some RAM so that there was less to write to the HD (probably the only time less RAM makes your Mac faser).

My iMac G5 randomly falls asleep during use.

A few weeks ago I was using my iMac and suddenly lost control of the cursor, cursor became invisible and computer went to "sleep" (ie; screen went black, "woke up" a few seconds later after moving the mouse). This problem has persisted in all sorts of conditions and uses. Usually the intial episode is followed by another shortly after. The problem happens a lot while streaming video on the internet. However, the computer also falls asleep when using photoshop.
The problem began when the hardrive was nearly full (15 GB left on drive). I cleared out many of the larger files (lossless music files) to gain 87 GB or so. Problem persists. I mostly use this computer for typical web stuff (email, facebook, videos on youtube and the like) and graphic design (Illustrator and Photoshop). Hard drive had never been defragged. I usually restart the computer when problem gets really bad.
I've searched various forums for a solution. Many argue about defragging, some mention OS reinstall, no real clear consensus seems to exist about why the problem occurs or what to do about it. Any ideas?
Specs: Mac OS X, 10.4.11, 2.1 GHz G5, 1 GB DDR2 SDRAM

Your problem sounds more like a heat problem. Try resetting the SMU:
   1. Shut down the computer.
   2. Unplug the computer's power cord.
   3. Press and hold the power button for 5 seconds.
   4. Release the power button.
   5. Attach the computers power cable.
   6. Press the power button to turn on the computer.
If that doesn't clear things up defragging won't do anything much, the best would be to try an
Archive and Install http://support.apple.com/kb/HT1710
which will give you s shiny new OS, but keep your prefs and settings. Make sure you select that option when reinstalling.

Computer falls asleep while streaming content to ATV

WOAH! Now with iTunes 7.6.1, while watching streamed TV show from my firewire-attached HD to my iMac, the computer is allowed to fall asleep! Bad. Very bad. This has never happened before now. While watching ATV, 'content not found' message pops up the second the iMac goes to sleep. Anybody else getting this?

Click your Apple logo in the upper tool bar of your computer>Select system preferences>under hardware select energy saver>select NEVER under put the computer to sleep when inactive
Its a temporary fix I suppose

My iMac falls asleep too often

I have mutliple users on this iMac and while I'll try to listen to itunes, if I haven't been active on the computer for roughly 5 minutes, the iMac falls asleep.
Is it something in my settings?

If iTunes is still playing, then only the Display has gone to sleep which is OK because it will help to save energy and make the display last longer.
If iTunes stopped playing then go to: Apple > System Preferences > Energy Saver and set Computer Sleep: to Never.
Then adjust Display Sleep: to whatever time you want.
Personally, I sleep my displays to save on energy if I am not using them.

Mac falls asleep while ordering Photobook

I use an iMac G4 with the latest OS and iPhoto.
When ordering photobooks, I experience my mac falling asleep (i.e. 'lighthouse mode'). My internet connection is wireless, and I know the Mac sometimes looses the connection with my airport; but finds it back my itself. iPhoto can handle this; it just stalls sending, and continues automatically.
The mac itself however falls asleep after 1h no activitiy; but iPhoto running and having network activity doesn't mean 'now activity'.
I can overcome the problem by switching of sleeping in energysaving options; but it's anoying.
I also experience it sometimes with programs like Realplayer.
Does anyone know how mac defines 'activity'; and how I can overcome this issue?

Martijn567:
Welcome to the Apple Discussions. I don't know how Apple defines "activity" but I know that you have to turn of the sleep option when you're encoding and/or burning iDVD projects to disk image or directly to disk. So it seems to be a system wide issue for operations that rely primarily only on CPU work. It's just the nature of the beast.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.

Takes a while to play sound via audio interface on iMac

I purchased iMac along with Focusrite Scarlett 6i6 USB audio interface and started having following problems from the beginning.
When I play video/music on itunes, logic or whatever apps that plays sound, it takes a while(about 20 sec) to play sounds. Sometimes it does not play sounds at all until I turn the volume halfway up on Focusrite Scarlett 6i6. It happens all the time when I play sound for the first time after turning the computer on. It happens when I start using the computer after a while. Sometimes it turns off the sound even when the music/video is being played. I had problem with latest Scarlett driver and still happens after switching to class compliant mode. It seems like it takes time for the computer to wake 6i6 via USB, but I am not sure. Please help!
computer Specifications:
- late 2013 iMac / flash 1TB / GTX 780M / 32GB RAM
- mavericks 10.9.2
- Just Scarlett 6i6 connected directly via USB
- no other devices connected, just apple bluetooth keyboard, magic mouse and touchpad
Softwares:
- Logic pro x latest version, Kontakt 5.3.0
- sample rate 44
Product Info:
- was using latest 6i6 driver but recently switched to class compatible mode

Well I have done the disk cleanup and it still didnt fix it. I just got this player yesterday too I have about 3.5 gigs on it. I didnt get my usb 2.0 system yet, but im just really worried about these long load times for the songs on the player. Im gona try loading some mp3s and see how those go.
edit... I just loaded up some MP3s and they start in about 3-4 seconds. A lot faster then my WMAs from yahoo, but still I was expecting mp3s to play instantly pretty much.Message Edited by Johnwashere on 05-2-2005 2:26 AM

I like to watch tvcatchup or sky go or I player on my iPad while falling asleep, the problem is that the iPad then stays on all night. I would like to find an app that allows me to set a timer for the iPad to switch itself off automatically.

Does such an app exist? Can anyone help me? Thanks

You can try the Sleep Timer.

My IMAC screen went to sleep and I have it set to enter a password upon waking it up. However, my bluetooth keyboard died while it was asleep and I replaced the batteries and tried to enter my password and it is not picking up my keyboard. What can I do?

My IMAC screen went to sleep and I have it set to enter a password upon waking it up. However, my bluetooth keyboard died while it was asleep and I replaced the batteries and tried to enter my password and it is not picking up my keyboard. What can I do? I will not let me enter my password to get in and trouble shoot the keyboard. Please Help!!

I pushed in the button on the top right corner. It turns a green light on and then it goes off. I held it in until it started blinking. It blinks for a bit and then the green light turns off. I am still not able to type my password. What should I do now?

There was a power outage while I was asleep and my Imac was on. Now it is comatose, no sign of life no matter what I do. Help anyone?

There was a power outage while I was asleep and my Imac was on. Now it is comatose, no sign of life no matter what I do. I pressed the power on button for over a minute and nothing happened. I unplugged the cable and changed the wall socket too but nothing happens. I hope My hard disc is not damaged and the data is not lost. How do I determine this with no technical knowledge?

Imac g5 crashes while asleep; can't boot from cd/dvd

My imac g5 crashes while asleep. Both the display and hard drive are set to sleep.
In trying to fix this problem with Apple tech support, I've discovered I can't boot from the cd/dvd. When I hold down the letter c while restarting, the disk ejects. I've tried three different disks: the install dvd, a Norton Systemworks bootable cd, and the bootable cd from AppleCare. All are ejected.
Have I got some hardware problem(s)?

Since we couldn't fix this over the phone, it's now at the Apple Store being fixed. They've replaced the power supply and, after I called again and made sure they tested it by having it sleep for a couple of hours (they couldn't wake it up after that), they're replacing the logic board.
I've been disappointed by the amount of hardware that's had to be replaced on this computer. I also had to replace the mid-plane assembly about six months after buying it in Sept. 2004.

How do I stop my external HD from falling asleep??? So, so Frustrating!!!!

Hey Apple users
OK, I have a Seagate 500GB external HD formated with MAC OS Extended. This puppy is great, very dependable, only ONE issue...
After not using it for a few minutes, it falls asleep, and when it needs to be used, it takes an annoying 6 seconds to start up. Working with audio and having live samples that are stored on this HD, not having them playback for a few minutes (ext. HD then falls asleep), then playing back the entire project with these files needing immediate use, the software CRASHES because it can't access the data fast.
I have no room on my PowerBook HD for much at all. This also causes problems in iTunes, wanting to play a song after not touching iTunes for a few minutes (when not playing), iTunes freezes for some seconds until it can access the songs on the external HD.
SO SO ANNOYING, the internal HD takes like .01 seconds to access data. And this HD takes like a painful 6 seconds Ugh,
How can I keep my external HD awake ALL THE TIME, unless my entire Mac is asleep??
Thanks!

Actually, this app. I mentioned above... HDriveAwake... is not a good idea,
it has many flaws, but it's decent software, just needs some improvements, main issue: consumes an incredible amount of RAM and Processing PWR while working.... (on my mac.. consumed 60+ %) & this is a bad thing if you use an EXTERNAL HD for stuff like audio/photo/video editing... I'm just going to get a Mac Pro G5 with like 4TB, I need it.... my bank account doesn't, but i do...

Why does it take 30 seconds to fall in sleep modus?

why does it take 30 seconds to fall in sleep modus?
Some time ago it took just a few seconds.

I have the same problem. It always takes about 30 seconds for my Mac Pro to fall asleep and it's driving me crazy.
I've got a Mac Pro early 2009 4.1. I've reinstalled the OS twice, disabled all startup items, uninstalled the Logitech Control Center, and unplugged all USBs. Only running keyboard and apple Mighty Mouse on bluetooth.
I've also disabled hibernate mode, and removed the sleep image from the boot disk.
On a pmset log, every thirty seconds the "com.apple.diskmanagementd" program creates a "PreventIdleUserSleep", then thirty seconds later it creates a "ReleasedIdleUserSleep". This repeats itself continuously while it's sleeping.
I've tried killing the process in Activity Monitor and it just starts up again 30 seconds or so later.
What could be causing this, and how can I stop it?
