Mac waking up again while sleeping
My Mac keeps waking up while sleeping. I thought Yosemite 10.10.4 had cured this problem, but it has come back again. Any ideas?
PowerMac, Mac OS X (10.7.5)

Step 5
Back up all data.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/var/vm
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.
A folder named "vm" should open. Inside it, there may be a file named "sleepimage". Move that file, and only that one, to the Trash, but don't empty yet. You'll be prompted for your password. Close the folder window.
Restart the computer and empty the Trash.
