My Mac Pro has recently started to wake from sleep on its own. This usually happens in the middle of the night, after I've gone to bed. I wake up in the morning and the computer is on.
Not sure how/why this is happening. Any ideas?
Mac Pro 2.8 (Early '08), Mac OS X (10.5.2), 10 GB RAM, 74GB 10k Raptor, 2x 750GB RAID, 23" ACD
Launch the Terminal 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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
syslog -k Sender kernel -k Message Req Wake
Post any lines of output that appear below what you entered — the text, please, not a screenshot.
Important: The name of your computer will appear in the output. If that information is private (for example, if the computer name contains your own name), edit it out by search-and-replace in a text editor before posting.

Thanks. Here's what came back:

In the Energy Saver preference pane, disable Wake for network access and delete any scheduled wake events.
Great. I didn't have any scheduled wake events, but "Wake for network access" was enabled. I disabled it, so we'll see if that works.
Thanks for your help.
Linc,
Your solution worked.
However, now I'm having a different problem.
I decided to schedule a regular, nightly back-up to an internal drive in my Mac Pro. I created a schedule in Energy Saver to wake the computer at 12am each night, and then put it back to sleep at 1am after the backup is complete.
It worked fine the first night; but since then, when I wake up in the morning the computer is on (it wasn't put back to sleep).
I ran the command you suggested in your original reply, and this is what came back:

Jul 23 00:00:02 Chriss-Mac-Pro-4 kernel[0] <Debug>: Wake reason: RTC (Alarm)
Do you know what EHCI is, and why it's waking my computer?
I did a little more research, and it seems EHCI is a high-speed USB bus?
What's strange, though, is that this EHCI waking only started after I scheduled the wake/sleep event. It wasn't happening before.
▹ System Preferences ▹ Bluetooth ▹ Advanced ▹ Allow Bluetooth devices to wake this computer: uncheck.
Thank you. Unfortunately, that option was already unchecked.
Disconnect all USB devices before going to bed. Test.
Okay, I disconnected all USB devices before going to bed. The computer was still awake when I woke up. Here's the log:

It looks like on the 24th and the 25th there are no entries for why it woke up. Or does "last message repeated 2 times" mean that on the 24th and 25th the wake reason was the RTC (Alarm)?
I guess the RTC (Alarm) is waking due to the schedule I set. But for some reason it's not going back to sleep as it should.
Does it sleep when idle, if you set a timeout of, say, 5 minutes?
No, it doesn't. I just set it to sleep in 3 minutes. Went to make a cup of tea, came back, still awake.
Test after each of the following steps that you haven’t already tried:
Step 1
▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 2
▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 3
▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor 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.
☞ If you’re running OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar of the Activity Monitor window, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
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.
Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.
Linc,
I realize this post was from last summer, but I'm now reading it and finding this helpful. I've run through all kinds of tests, and it turns out my computer has this same issues with EHCI. I don't know what to do, and your last suggestion to do a safe mode login did not do the trick (I put my Mac Pro to sleep and within 10 seconds it wakes up, and I also hear it cycling through--as if "waking up" even when I am working on the computer). So I am going to try to reinstall the software.
But I wanted to ask you, because you seem to know a lot, do you think I will need to reinstall all of my software (Word, SPSS, quicken) after I reinstall the system software. That would be such a hassle I might call in tech support before trying it (I have applecare for my MBAir but not my Mac Pro, so would need to pay, which I'm okay with but hoped to avoid).
So if you could tell me if I'll have to reinstall all of my personal software as well that would help. By the way, here is the output I get in my Terminal suggesting the EHCI is my problem:
