The USB idea is very plausible because Apple keeps the USB hub fully powered in S3 (sleep), S4 (hybrid sleep) & S5 (off) so folks can charge their iPods off of the USB bus while the machine is down. Any supply side issue to the power would likely cause the USB bus to be the first to suffer and likely cycle into and out of the USB low power state as a means of self preservation. That would cause the various attached peripherals to respond in kind fooling the system into thinking that input from the peripherals was received. Just a guess though based on what the submitter wrote.
For whatever that's worth, I have a USB LaCie Drive which keep my computer from sleeping :(
At least, as long as I don't
a) eject the drive,
b) turn the drive off (or hot swapping it) or
c) shuting down my computer!
But that's because my drive doesn't automatically go to sleep. Dargn LaCie!
I also struggled with tracking down the cause of a self-waking Mac..for years. I scoured every website and forum I could find, and finally tracked it down to the software used to drive some MacAlly keyboards.
I loved my iMediakey keyboard, but the problem—caused by the MacAlly software—has never been fully addressed or fixed, as far as I know.
I tried tech support, and as careful as I was in explaining what I had done in trying to troubleshoot, including making pointed reference to linkes on their own website, they only sent me copy/pasted info—the exact same directions I told them I had already read and performed. It was clear that they didn't read my emails at all.
I got so pissed off at MacAlly's lack of any kind of personal help I yanked the keyboard, their software, and will NEVER recommend it to anyone.
Which software was causing the problem? I've got a MacAlly keyboard, and wonder if that's my issue, too.
I've had the same trouble with my PowerBook. But it occurs only rarely, maybe a couple times a month. I don't have a USB hub plugged in, just a USB mouse, ethernet, and phone line. I wonder if power flickers in the phone line could do it?
Very sometimes the ethernet can be a cause of it actually, try it without the ethernet plugged in?
If you're using a PowerBook/iBook/MacBook(Pro), the easiest way to stop this happening is to simply unplug your power lead.
Oddly, the USB-device-waking-up-your-Mac 'feature' only occurs when running on mains power.
I use a USB KVM switch for my MBP and another computer and used to get frustrated by the switch waking the Mac for no reason..
Very interesting that Macs supply power to the USB hub even when switched off! I didn't know that, but I could easily make use of it!
I've actually had several instances w/ my MacBook Pro of either not going to sleep, or waking up, or not waking up. I seem to have minimized these by unchecking two items.
1. From Bluetooth preferences uncheck 'Allow Bluetooth devices to wake this computer' -- of course this means your won't be able to wake your computer w/ your bt kbd or bt mouse.
2. From Energy Saver prefs, under options, uncheck 'Wake for Ethernet network administrator access'.
My wife and I have identical 17' MacBok Pros. About twice a month, hers wakes up after its lid is closed and it goes to sleep. When it does this it gets very hot by the next morning and cannot be awoken - we have to crash it by holding in the power button.
I know we have turned off the 'Bluetooth will wake' but it keeps turning itself back on after several days. we'll have to check the 'Wake on LAN' setting.
There is nothing plugged into our MBPs when they are asleep except power and gigabit ethernet.
I have exactly the same problem with my G4. I found that only shutting down the light of the room causes the computer to wake from sleep..
Same problem at my mother's house, in another city, with another G4.
I tried to use different surge protected plugs, with no result :/
I take it you're *not* UK based.. That's what the ground pin is for :-)
That and preventing major electrical shocks.
Actually, you might want to reverse that. Opening the light to make to wake up the computer makes more sense.. ;)
You know, you come to your office, you turn on the lights, your computer wakes up and starts rsync, get mails and stuff.. ;) :)
robindwilliams : I'm in France, and the electric installation is old, ok, but not that old !! We have the ground pin ^____^
Yes. But the next question. What was the cat looking at on the internet or was it just chasing the mouse.
I've got 3 devices that do this:- Lacie USB harddrive (Unless I unmount it first - my generic USB/Firewire enclosures doesn't do this)
- Terratec DVB-T digital TV device (but strangely enough not my equinux TV stick)
Some USB devices, especially hubs and not only cheap ones cause the sleep problems. With my G5 Quad I either disconnect the hub or have to make it sleep two, three, five or more times. Once it gets sleepy enough, it sleeps well though. The solution is to disconnect the hub. But I've got this problem with some hubs, regardless of their price. And I don't get it with some, regardless of the price too. Workaround to this if I don't want to diconnect the hub was to require password to wake from sleep (System Preferences) and whenever the machine gets awake it goes back to sleep by itself in a minute when no password is entered.
I tried this on a Mirrored Drive Doors G4 dual 1.25 GHz running OS 10.5.2, which has had this undesired automatic wake from sleep problem under OS 10.4 and now 10.5. I put it to sleep, then woke it, and didn't enter a password when asked. After about 30 seconds, the screen saver activated, but the Mac stayed powered up. I knew it was too good to be true. If it had really worked, this would have been one of the most elegant solutions for those Macs for which unplugging and replacing hardware just to get it to stay asleep, and all the other fixes (turning off useful options, etc.), aren't a practical solution. Hulagain mac os. Maybe someone has written a utility that will keep putting the Mac to sleep every time it sees that it's woken up, until you really want it to wake up--often, Macs that won't stay asleep, will sleep a lot longer after they've been put back to sleep several times in a row.
Oops--don't save that script using Script Editor's 'Stay Open' option, or else the app will stay running even after you click its 'Cancel' button, but it won't do anything after that until you quit from it and re-launch it. Without the 'Stay Open' option, it will quit if you click its 'Cancel' button, and then you just have to re-launch it to activate it again, which is the desired behavior.
Where can I get one of those talking cats?
Carpathian Night Mac Os X
i too have suspected the usb infrastructure (i've a belkin hub that i don't entirely trust). but what really annoys me is after whatever awakens my imac (core 2 duo), it stays awake, even though it's configured to put itself to sleep after 30 minutes idle.
I once had a problem with my macbook pro where one night it suddenly stopped sleeping. It had been fine for months before that, but after that night it wouldn't sleep for more than a couple of minutes. Finally I figured out that my built in iSight camera had gone bad. As a result, the USB subsystem was constantly trying to identify the half working camera, but could only tell the it was an unknown USB device. I had to send the computer to Apple and get the camera replaced.
Carpathian Night Mac Os Catalina
I have a completely different one. I have a MacBook Pro and a Dell 30' monitor. If I sleep the MBP with the monitor plugged in, it seems to go to sleep but wakes immediately. If I unplug the monitor before sleeping everything works fine. I don't use the monitor's built-in hub since it gets powered down when the monitor is turned off (nice going Dell! :( ). Quite annoying.
I have a Canon 4400F scanner attached to a Belkin USB 2.0 hub (iMac G5 rev C). If I put the computer to sleep while the scanner is plugged-in to the hub, the system wakes up immediately. Only 2 remedies - plug the scanner directly into the iMac (not practical as the USB cable (6ft) is not long enough (I don't want to buy a 10 ft cable), or unplug the scanner from the Hub. I chose the latter, in fact I keep it unplugged until I need to use it. Doing this allows the computer to sleep as intended.
A few people have mentioned turning off the Wake-on-LAN feature, also referred to in the Energy Saver control panel as 'Wake for Ethernet network administrator access.' This feature is unlikely to cause the problem, however. When this is on, the Ethernet interface listens for a specially formatted packet instructing it to wake up. Among other things, this packet must contain your ethernet card's MAC address repeated 16 times consecutively. There is effectively zero chance of a random packet on the network triggering this accidentally, so unless somebody is intentionally waking your computer remotely, this shouldn't cause it.
Having said that, turning that feature on tells your computer to keep the ethernet interface powered while the computer is asleep, so I guess there's a chance that a power fluctuation could temporarily unpower the ethernet interface, which might confuse and wake the computer, though I doubt it.
Wireless keyboards and mice (both USB and Bluetooth) can wake a Mac too. Also, self-refreshing Web pages can do this, like CNN's home page.
this is still plaguing me with two insomniac episodes this week. i filed a bug report at apple (#5815010 iMac randomly awakes from system sleep - won't go back to sleep afterwards 23-Mar-2008 10:24 AM Open). dunno that it'll help, but it can't hurt.
i removed all the usb devices that were plugged into my machine, other than the mouse & keyboard. the wakeup is the same each time: a bluetooth/usb event. i first noticed the wake-up/insomnia problem after i enabled bluetooth for a wireless mighty mouse. that died a cruel & unusual death so i disabled bluetooth again. the problem remains ..
That was the cause of my problem, see:
How can I help a loved one (who is not human) overcome insomnia?
I was watching the system log using console and chased after the BlueTooth thing for quite a while, ('IOBluetoothHCIController::restartShutdownWL this is a wake from sleep') but that turns out to be a red herring, it's an effect, not a cause.
I dragged a copy of VersionCue onto the Desktop and deleted it from /Library/StartupItems (not your user library, the top level library is where it's installed). Oddly enough I realized that I should have removed it's pref pane so I put it back and had to authenticate the move. Poof.. the problem was gone. I was going to uninstall it properly but just moving it around fixed something so for now I've left it.
So it had something to do with VersionCue even though it's still there. It's turned off but it's always been turned off.
On another note for someone else with sleeplessness problems I have an ancient HP 6MP printer connected via a Belkin USB to Parallel adaptor (via a 16 foot active USB cable as well). If the printer is turned off sometimes the computer constantly gets USB wake-ups (USB caused wake event). So I was troubleshooting two problems at the same time.
been a while but the answer is no. i've since upgraded to 10.5 & cs3 (& declined to even install version cue on that install). i still have occasional insomnia bouts with my machine.
Operating system | macOS |

Service name | Dock.app |
Type | Taskbar |
The Dock is a prominent feature of the graphical user interface of macOS. It is used to launch applications and to switch between running applications. The Dock is also a prominent feature of macOS's predecessor NeXTSTEP and OpenStep operating systems. The earliest known implementations of a dock are found in operating systems such as RISC OS and NeXTSTEP. iOS has its own version of the Dock for the iPhone and iPod Touch, as does iPadOS for the iPad.
Apple applied for a US patent for the design of the Dock in 1999 and was granted the patent in October 2008, nearly a decade later.[1] Any application can be dragged and dropped onto the Dock to add it to the dock, and any application can be dragged from the dock to remove it, except for Finder and Trash, which are permanent fixtures as the leftmost and rightmost items (or highest and lowest items if the Dock is vertically oriented), respectively. Bubble burst mac os. Part of the macOS Core Services, Dock.app is located at /System/Library/CoreServices/.
Overview[edit]
In NeXTSTEP and OpenStep, the Dock is an application launcher that holds icons for frequently used programs. The icon for the Workspace Manager and the Recycler are always visible. The Dock indicates if a program is not running by showing an ellipsis below its icon. If the program is running, there isn't an ellipsis on the icon. In macOS, running applications have been variously identified by a small black triangle (Mac OS X 10.0-10.4) a blue-tinted luminous dot (Mac OS X 10.5-10.7), a horizontal light bar (OS X 10.8 and 10.9), and a simple black or white dot (OS X 10.10-present).
In macOS, however, the Dock is used as a repository for any program or file in the operating system. It can hold any number of items and resizes them dynamically to fit while using magnification to better view smaller items. By default, it appears on the bottom edge of the screen, but it can also instead be placed on the left or right edges of the screen if the user wishes. Applications that do not normally keep icons in the Dock will still appear there when running and remain until they are quit. These features are unlike those of the dock in the NeXT operating systems where the capacity of the Dock is dependent on display resolution. This may be an attempt to recover some Shelf functionality since macOS inherits no other such technology from NeXTSTEP. (Minimal Shelf functionality has been implemented in the Finder.)
The changes to the dock bring its functionality also close to that of Apple's Newton OSButton Bar, as found in the MessagePad 2x00 series and the likes. Applications could be dragged in and out of the Extras Drawer, a Finder-like app, onto the bar. Also, when the screen was put into landscape mode, the user could choose to position the Button Bar at the right or left side of the screen, just like the Dock in macOS.
The macOS Dock also has extended menus that control applications without making them visible on screen. On most applications it has simple options such as Quit, Keep In Dock, Remove From Dock, and other options, though some applications use these menus for other purposes, such as iTunes, which uses this menu as a way for a user to control certain playback options. Other Applications include changing the status of an online alias (MSN, AIM/iChat etc.) or automatically saving the changes that have been made in a document (There is no current application with this feature made available for macOS). Forbidden dessert ii: the third dimension (sodeep) mac os. Docklings (in Mac OS X 10.4 or earlier) can also be opened by using the right-mouse button, if the mouse has one, but most of the time either clicking and holding or control-click will bring the menu up.
In Mac OS X Leopard, docklings were replaced by Stacks. Stacks 'stack' files into a small organized folder on the Dock, and they can be opened by left-clicking.Stacks could be shown in three ways: a 'fan', a 'grid', or a 'list', which is similar to docklings. In grid view, the folders in that stack can be opened directly in that stack without the need to open Finder.
In iOS, the dock is used to store applications and, since iOS 4, folders containing applications. Unlike the macOS dock, a maximum of 4 icons can be placed in the dock on the iPhone and the iPod Touch. The maximum for the iPad however is 16 icons (13 apps and 3 recently opened apps). The size of the dock on iOS cannot be changed.
When an application on the Dock is launched by clicking on it, it will jump until the software is finished loading. Additionally, when an application requires attention from a user, it will jump even higher until its icon is clicked and the user attends to its demands.
Design[edit]
The original version of the dock, found in Mac OS X Public Beta to 10.0, presents a flat white translucent interface with the Aqua styled pinstripes. The dock found in Mac OS X 10.1 to 10.4 removes the pinstripes, but otherwise is identical. Mac OS X 10.5 to 10.7 presents the applications on a three-dimensional glassy surface from a perspective instead of the traditional flat one, resembling Sun Microsystems' Project Looking Glass application dock.[2] OS X 10.8 to 10.9 changes the look to resemble frosted glass with rounded corners. OS X 10.10 and later revert to a two-dimensional appearance, similar to Mac OS X 10.4, although more translucent and with a iOS 7 blur effect.
In iPhone OS 1 to 3, the dock used a metal look which looks similar to the front of the Power Mac G5 (2003-2005) and Mac Pro(2006-2012 or 2019-). iPhone OS 3.2 for iPad and iOS 4 to 6 adopted the dock design from Mac OS X 10.5 to 10.7 which was used until iOS 7, which uses a similar dock from Mac OS X Tiger but with iOS 7 styled blur effects.[citation needed] In iOS 11, the dock for the iPad and iPhone X is redesigned to more resemble the macOS dock.[3][4]
Related software[edit]
The classic Mac OS does have a dock-like application called Launcher, which was first introduced with Macintosh Performa models in 1993 and later included as part of System 7.5.1. It performs the same basic function.[5] Also, add-ons such as DragThing added a dock for users of earlier versions.
Microsoft implemented a simplified dock feature in Windows 98 with the Quick Launch toolbar and this feature remained until Windows 7, where it was replaced by the Superbar, which implements functionality similar to the macOS Dock.
Various docks are also used in Linux and BSD. Some examples are Window Maker (which emulates the look and feel of the NeXTstep GUI), Docky, and Avant Window Navigator, KXDocker (amongst others) for KDE and various other gdesklet/adesklets docks, AfterStep's Wharf (a derivation from the NeXTstep UI), iTask NG (a module used with some Enlightenment-based Linux distributions such as gOS) and Blackbox's Slit.
Criticism[edit]
Bruce Tognazzini, a usability consultant who worked for Apple in the 1980s and 1990s before Mac OS X was developed, wrote an article in 2001 listing ten problems he saw with the Dock. This article was updated in 2004, removing two of the original criticisms and adding a new one. One of his concerns was that the Dock uses too much screen space. Another was that icons only show their labels when the pointer hovers over them, so similar-looking folders, files, and windows are difficult to distinguish. Tognazzini also criticized the fact that when icons are dragged out of the Dock, they vanish with no easy way to get them back; he called this behavior 'object annihilation'.[6]
John Siracusa, writing for Ars Technica, also pointed out some issues with the Dock around the releases of Mac OS X Public Beta in 2000. He noted that because the Dock is centered, adding and removing icons changes the location of the other icons.[7] In a review of Mac OS X v10.0 the following year, he also noted that the Dock does far too many tasks than it should for optimum ease-of-use, including launching apps, switching apps, opening files, and holding minimized windows.[8] Siracusa further criticized the Dock after the release of Mac OS X v10.5, noting that it was made less usable for the sake of eye-candy. Siracusa criticized the 3D look and reflections, the faint blue indicator for open applications, and less distinguishable files and folders.[9]
Thom Holwerda, a managing editor OSNews, stated some concerns with the Dock, including the facts that it grows in both directions, holds the Trash icon, and has no persistent labels. Holwerda also criticized the revised Dock appearance in Mac OS X v10.5.[10]
