Snow Leopard 10.6.8 automatic sleep issues

Hey,
I have a 27" Apple iMac with an i5 processor and 8GB of RAM running Snow Leopard 10.6.8. I have had it for about a year and a half and for the first 15 months or so it was perfect. However in the last few months I have been having problems with automatic sleep.
When the computer was working correctly if I had set the display to sleep at 5 minutes and the computer to sleep at 15 minutes in energy saver, then if the Mac was idle it would sleep at these times. If however I was say printing a lot of pages or downloading a large file or ripping a DVD, then the computer would not sleep even if the 15 minutes had elapsed but once it had completed its task and 15 minutes had passed, it would sleep. This was great if I was leaving home or going to work as I could rely on my Mac to finish its task and then sleep and so not waste electricity.
So when the problems started, first my Mac would never sleep automatically and this was for a while fixable by simply clicking "restore defaults" in the energy saver settings. Then no matter what it would never sleep unless I set it to sleep manually and now after trying a solution from Apple care (restoring disc permissions in disc utility), the Mac sleeps once the prescribed time has elapsed no matter what I am doing be it listening to iTunes, downloading a file and so on.
In other user accounts this problem also abounds and so doesn't appear to be related to third party software. On the recommendation of an Apple care guy I reinstalled Snow Leopard from disc (the lesser install that does not erase the hard-drive and takes about 45 minutes) and after this the sleep function was working properly. However as soon as I updated the Mac to bring it up to date after the re-install, the problem started again. This gives me the impression that some update from a few months ago is causing this issue.
According to the Apple guy, there is no known solution for this and he tried to sell me a load of nonsense about using third party freeware like caffeine and please sleep to solve the problem. However these solutions are useless unless you are around to ultimately put your Mac to sleep manually and/or turn on/off the third-party software.
This may not seem like a big issue, but when I have my Mac perform many tasks while I am not present, if it stays on indefinitely afterwards, then it is really wasting a lot of electricity.
Has anyone else had this or a similar issue and found a solution? I know I could upgrade to Lion and try that, but if that doesn't work then I will have wasted €24, plus I was hoping to wait until as many of the kinks had been worked out of Lion via patches before updating.
Has anyone had any experience with trying to get Apple to replace a computer that is still under Apple Care warranty over a year after purchase as if it continues, my Mac has lost a LOT of its functionality for what I need it to do and I am no longer happy with it.
Thanks.

Your post is pretty lengthy and I have to admit I didn't read it all. Please try restarting in Safe Mode, if that doesn't work please do both a SMC and PRAM reset. These may take 2-3 attempts.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Since Snow Leopard, Mac Pro will not sleep with Apple wireless keyboard

I have an odd problem, now on 2 Mac Pro (Nehalem) with 10.6.1:
Since Snow Leopard, the system will not sleep as long as a) the user is logged on (any users/profile) and b) the Apple aluminum wireless keyboard is 'attached'.
If I log off first, sleep works fine. If I turn the keyboard off first, it's fine. But if hitting 'sleep' when logged on, the screen turns dark, sleep process begins, but the system comes right back (with a note 'keyboard disconnected'.
It's as if the keyboard disconnects after sleep, but the system still monitors it, and wakes up.
Note: Wake for bluetooth devices IS NOT ENABLED!
Here is the console log (relevant info):
10/18/09 4:57:33 PM kernel System Sleep
10/18/09 4:57:48 PM kernel Wake reason = UHC1

Does anyone have any idea? While on, the keyboard never disconnects - i.e. I don't have any other issues with BT or the keyboard (this is the 2nd I tried).
Also, my apologies for double-posting this earlier in a different forum; cheers!
Thanks,
Dan

Hi,
and thanks for posting that.
That's too bad. I am probably going to log off if needed, rather than going wired, but I can't believe that this might be more prevalent than just me and there is no 'fix'...
Anyone ?!
Thanks as always,
Dan

Snow Leopard users: Turn off automatic date and time in System Preferences immediately

http://arstechnica.com/apple/2014/12/apple-automatically-patches-macs-to-fix-sev ere-ntp-security-flaw/
When exploited, the NTP flaw can cause buffer overflows that allow remote attackers to execute code on your system.
What this means is that, if you allow date and time to be set automatically by outside servers, you risk having your computer taken over.
This is a critical issue, it's being exploited as we speak, and Apple has not provided the update to Snow Leopard users, only to 10.8/Mountain Lion and above. I strongly doubt Apple will ever get around to issuing an update for Snow Leopard, or they would have already. Chances of that happening are close to zero

To me 10.6.8 is still the best OS X Apple ever released and I patched my system just like the shellshock back in September. It's really easy if you have some basic shell skills and XCODE installed,
Here is what I did, it may save you some time:
open the terminal app
1) Download the source code, apply the patch (I got the source code links from the ntp site)
cd ~
mkdir ntpd-fix
cd ntpd-fix
curl http://www.eecis.udel.edu/~ntp/ntp_spool/ntp4/ntp-4.2/ntp-4.2.8.tar.gz | tar zxf -
2) Patch and compile the ntp source code
cd ntp-4.2.8/ntpd
curl http://bugs.ntp.org/attachment.cgi?id=1165 | patch -p1
cd ..
./configure && make
3) Open the system preferences - Date & Time - uncheck Set date and time automatically (to stop the process)
4) Rename the old object and then replace/copy them with the new objects
cd /usr/bin
sudo mv sntp sntp.old
sudo mv ntpq ntpq.old
sudo mv ntp-keygen ntp-keygen.old
cd /usr/sbin
sudo mv ntpdc ntpdc.old
sudo mv ntpdate ntpdate.old
sudo mv ntpd ntpd.old
cd ~/ntpd-fix/ntp-4.2.8
sudo cp sntp/sntp /usr/bin
sudo cp util/ntp-keygen /usr/bin
sudo cp ntpq/ntpq /usr/bin
sudo cp ntpdc/ntpdc /usr/sbin
sudo cp ntpdate/ntpdate /usr/sbin
sudo cp ntpd/ntpd /usr/sbin
sudo chown root:wheel /usr/bin/sntp
sudo chown root:wheel /usr/bin/ntp-keygen
sudo chown root:wheel /usr/bin/ntpq
sudo chown root:wheel /usr/sbin/ntpdc
sudo chown root:wheel /usr/sbin/ntpdate
sudo chown root:wheel /usr/sbin/ntpd
5) Open the system preferences - Date & Time - uncheck Set date and time automatically (to start the process)
6) Done.
-- update time manually
sudo ntpdate -u time.apple.com
-- check ntpd version (should now be: ntpd [email protected])
sudo ntpd --version

Imac with snow leopard does not go to sleep after installing magic? trakpad

i have a 9,1 imac and still have snow leopard(10.6.8) and installed magic Trackpad two weeks ago since then the computer does not go to sleep. I have changed energy saver settings but no effect. Only programs running are gogle new and gmail. Does any one has come across this problem, any solutions?
Thanks

I had the download file open all the time and closing that has solved (looks like) the problem. However, this was not an issue while I use the regular mouse.

Snow Leopard 10.6.2 - Time Synch Issue

Hi,
I have an older MBP that was just rebuilt with Snow Leopard. Everything is working fine but a weird issue I ran into which is the system time. The date and time is set in System Preferences for CST and using an NTP server. The displayed time is correct. Here is what I ran into and my attempts at troubleshooting.
Details:
1.Entourage displays message 6 hours ahead
2.Tried Outlook through Citrix on the MBP and the message times are off by 6hrs as well
3.Tried Outlook through Citrix with a different AD acct. Problem still exists.
4.Tried Outlook through Citrix on another system and the message times are correct
5.Tried logging in as admin on the MBP and tried Outlook thru Citrix. Problem still exists.
6.Played with Date/Time settings in System Preferences by changing zones and going back to CST
7.In Terminal, the time displayed after running DATE is off by 6hrs and shows it using UTC
8.I modified the NTP.conf file to use tick.usno.navy.mil and still see the time off running DATE in Terminal
9. Manually set the time. No success.
Any suggestions would be greatly appreciated.
Thanks,
Paolo

Not sure what your trouble is, but you might try these ntp command to get more info about time. I am guessing that ntp is fine, but that Outlook and Entourage are looking somewhere strange for the timezone information. I am using the ntp pool to get time...
In /etc/ntp.conf:
server time.apple.com

server 0.north-america.pool.ntp.org minpoll 12 maxpoll 17

IMac Automatic Sleep Issues

Hello,
A few months ago I purchased a iMac 20" 2.66Ghz factory default model. The machine has been performing beautifully. Although I've been encountering one major issue. The iMac will manually go into sleep mode, but it will not automatically do so.
So I have tried various different methods to get this guy running properly. So far, I have tried clean reinstalling Leopard (from the restore CD's) twice, resetting the vram, the SMU, I tried different Leopard updates - including 10.5.4, 10.5.5, and 10.5.6. I do not have any third-party accessories plugged into the unit. I disabled Bluetooth since I do not use it, but Airport Extreme is always in use.
The ram, hard drive, and all factory installed hardware is showing up and working properly.
I'm stuck on what I should do. So far, the only solution has been to use a application called "PleaseSleep," which essentially forces the machine to go into sleep mode based on the designated time set in the energy saver preference panel.
I have read many other threads related to this issue here. But I am unable to find a clear solution.
Thanks!

How do you have your Sleep options set in the System Preferences/EnergySaver/Sleep panel?
"the only solution has been to use a application called "PleaseSleep," which essentially forces the machine to go into sleep mode based on the designated time set in the energy saver preference panel." Third party apps that control anything in your System Preferences panel can cause more headaches they they are worth.
If you haven't tried running the Apple Hardware Test, it might be a good thing do. Process of elimination: http://support.apple.com/kb/HT1509
"The ram, hard drive, and all factory installed hardware is showing up and working properly."
Have you actually booted from your restore disk and checked the hard disk for errors? If not..
Follow these instructions to verify the hard disk for errors:
Open Disk Utility, in the Utilities folder in the Applications folder.
Select your disk, and click First Aid.
Click Verify Disk.
If the disk needs repairs, do one of the following:
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Repair Disk. When Disk Utility is finished, from the Menu Bar select Utilities/Startup Disk. Select MacintoshHD 10.5 in the window and click: Restart
If you don’t have a Mac OS X Install disc, restart your computer while holding down the Shift key. As your computer starts up, it performs a disk check similar to the one Disk Utility performs.

13" Macbook (black), Snow Leopard, Boot Camp, Windows 7 display issue

OK I don't know where to post this. I couldn't find an appropriate forum under Boot Camp (nothing for display). Apologies if this is the wrong forum.
I am attempting to run Windows 7 using Boot Camp. Here is the behavior:
Booting Windows 7 without any monitor plugged in works fine.
Booting with an external monitor plugged in, I get the display on the external monitor. Now when I unplug the external monitor, the LCD display backlight is off and is completely dim. I had to reboot it in order for the LCD display to work again.
This is not a macbook display issue. But it has to do something with the way Windows 7, BootCamp are compatible with a macbook. Anyone seen this or know what the fix is?
Thanks

I can not get my Win 7 (32) os to see my Mac 10.6 partition. Is there something I need to set or turn on to get this to work?
As for your problem, perhaps Windows is not seeing the FireWire bus?

Reinstalling Snow Leopard after Mountain Lion! Firmware issue!!

Greetings!
I have a Mid 2011 iMac - which I wish too sell so I can get the new iMac when they are released.
Originaly my iMac came with SL, which I have the factory reinstall dvd.
Over time, I have upgraded the OS from SL to Lion, then ML. Which I purchessed via the App Store under my iTunes account.
Now I wish to sell my iMac, I have tried doing a format and install of SL using my original SL disc. But when I try to install, I get the bleeping sound.
I can format and installed ML via wifi download, but naturaly that requires my appleID, so thats no go for selling my iMac to someone.
One thory is that I did an offical apple firmware update on my iMac, I can't remember which one, Bluetooth, Firewire, wifi, I don't really remember. But I think that is stopping me from installing SL again.
Any help would be great.

Thanks for the reply, I will try that tonight.
I'm working on this thory I found on google....
'Booting a new MacBook Pro (Late 2011) from a retail 10.6.3 disc resulted in a black screen and a repeating 3 beep pattern. This is due to missing Sandy Bridge drivers. Apple will ship a 10.6.6 (iMac) or 10.6.7 (MacBook Pro) installer disc'
My OS was the 10.6.3 that came with my iMac. I phoned Apple, they wanted me to pay £18 for 10.6.6
Hmmmmmm!

Snow Leopard Crazy Problems, And Poor Perfomance Issues?

I got my first G5 a few years ago and it was totally rock solid, and never missed a step, until I traded it in on a Mac Pro to get SL and be able have better performance and the ability to upgrade later on in Final Cuts Studio 3. I have never ever experience such a horror of crap until I installed SL last night. This is the biggest disappointment I have ever seen from Apple!!! Period!,
1. I cloned a backup to a Free Agent USB Drive, thank god
2. When I got SL installed by just upgrading 5.8, I got ton on problems like
a message saying that I need to restart , so I did, and did , and again,
30 of so more times until, I tried repairing permissions etc, never worked.
3. I finally erased the drive and tried to reinstall a fresh install, got SL to
work finally but now I am getting a error message "Your Mac OS X startup Disk
has no more space available for Application Memory? the interface is slow
like a window machine! My system drive is 6 gigs, and I have 6 gigs of memory
4. Now I am cloning to a spare drive from the Free Agent backup and thinking
about not even using the drive with SL on it.
Sorry about the whining guys, but this fustrating!, your imput is very much
helpful, and I thank you all for being here!
Tim C.

When you took your G5 backup... I hope you did not use it to (home directory) to then upgrade to SL.
Reason is that there is a lot of older code and the upgrade from PPC to the Intel was never a clean one. There where a number of posts that addressed this specifically. There is a manual way to move the files from your home directory but the rest, you are better off with a re-install.
I did the migration from the G5 to the MacPro and it was problematic. Did a few searches and found that this was the problem. Migrated based on the recomendations given on these boards and got all my stuff working just fine and the update to SL also worked just fine... Its all in the process I guess.

Latest Security Update for Snow Leopard

After installing the latest Security Update for Snow Leopard, my MacPro is having sleep issues, it will not wake up, the drive seems to be spinning w/o awakening.. I have to manually shut down and reboot. Then all is fine.
How do I fix this????
MacPro 10/6/8
2 x 3 GHz Quad-Core Intel Zeon
12 GB RAM

Don, I did check with the update and I must have installed it because there is nothing available. This problem started yesterday, 2/11/12 and is continuing today.
I am checking to see if the update is the issue, or if my computer has a different issue. The only problem seems to be the disk spinning at wake up from sleep. I can shut down and reboot. Thankfully.

MacBook Pro won't wake from sleep after installing Snow Leopard

If my MacBook Pro is running while closed with an external display and I unplug it from the display it goes to sleep - as indicated by the white light and the front pulsing. If I then open the MacBook the display remains blank and it is completely unresponsive to any keys or track pad input.
The only thing it responds to at that point is holding the power button down until it powers down and then restarting - loosing all work in progress at that point.
Before installing Snow Leopard the Mac would wake reliably when opened from this state.

Good advice Mike! When in doubt check the ScreenSaver settings.
Definitely seems that it has a problem with that pic... In my case, selecting any images instead of the default setting (no screensaver) seems to have cured my non waking issue on my early Macbook Pro in Snow Leopard.
My original problem was that no amount of trackpad input woke it, but the space bar did. The space bar seemed to wake it up with the previous Screen Saver setting. Now trackpad wakes it up (even from total sleep as well as screen saver), too. Might be nice to know about if this is an intended 'feature' as a security trick. Otherwise I consider this a bug.
My vote is that it's a bug.

Leopard won't wake after sleep

When I go to my computer in the morning it will not wake.
It hangs at a blue screen....this never happened with Tiger!
I have to do a restart by powering down holding the power button.
Any possible fix?
thanks

CS4 and Snow Leopard causing menu problems?

I'm a long long time Dreamweaver 8 Windows user. Since Dreamweaver 8 has been crashy on the Mac, I've stuck there for a long time.
I downloaded CS4 trial and upgraded to Snow Leopard at about the same time.
The main problem is that pulldown menus seem to be very buggy. I've got to click them a bunch of times and the computer seems to hang till I've somehow managed to click it. What's up with that? It's ONLY in Dreamweaver. (I don't use other CS4 products so I would know otherwise).
Also every time I go to refresh, or upload or download, it seems that the "Cannot do the operation because DW is communicating with the server already" message comes up. The second try it seems to work fine... What's up with that?
Also, why has Dreamweaver not yet added a pulldown which allows coders to jump quickly to functions? If there's one reserved word that is EVERYWHERE, it's functions. How come every other IDE has this? It's 2009 for goodness sake!!!
I'm probably NOT going to spend the money at this point... My hopes for improvement for DW's core functionality after all these years have not been met.
If you want to see a freaking awesome program that has much of the crucial information figured out beautifully, see scootersoftware's beyondcompare3. PC only, but what an amazing piece of work (the threading is incredible...)
Oh, and code hints and tag completion seems to have disappeared...

Suffice it to say, Snow Leopard (Mac OSX 10.6) has issues with many apps & utilities.
http://www.informationweek.com/news/hardware/mac/showArticle.jhtml?articleID=219500778
http://news.cnet.com/8301-19882_3-10322624-250.html
"Snow Leopard also automatically installs Java SE 6, meaning programs that require previous versions of Java may not run properly."
I don't use Mac, but I take this to mean that rolling back your Java may improve things. Not sure, but it might be worth a shot (albeit in the dark).
Good luck,

Snow leopard Active directory account taking a long time to verify password

Hi,
My mac is configured to use an active directory account (windows small biz server 2008), i configured a mobile account when i was still under leopard and it was working fine. Since i upgraded to snow leopard i started experience the following issues:
When i am out of the office (not connected on the domain), logging in to my mac take about 5min after i type the password, same thing when the mac awakes from sleep, i type my password and it says verifying password and this takes about 5 minutes to complete! Another issue i am experiencing is that whenever i put my mac to sleep, when it wakes up most of the running applications crash and i have to restart them. i was hoping 10.6.2 would fix that but it didn't.
Sorry for the long post. Thank you in advance for your support!

I guess we will have to wait for someone to give us a clue, or for apple to release 10.6.3 .
