Cmd-Tab Problem

My computer seems to have something wrong with it. It seems that what ever I do with the mouse it triggers the Cmd (Apple)-Tab keyboard shortcut and prohibits me from using the computer since the pop up window with the current working applications remains active and doesn't go away. If I click on one of the working applications in the pop up then it goes away until I click anywhere else and the dreaded pop up , pops up again. Anyone have an idea?

Hello merlinou
Welcome to Apple Discussions
Sounds like one of your mouse buttons or side buttons are set to Application Switcher, go to: *Apple > System Preferences > Keyboard & Mouse > Mouse* and check.
The standard settings are:
Left button --- Primary
Right button -- Secondary
Center button - Dashboard
Side buttons -- Expose
note: I generally run with my side buttons off, because they are touchy and tend to activate accidently.

Wierd Problem with task switching ( cmd+tab)

I rather put an image, because it's rather difficutl to explain:
[img]http://img123.imageshack.us/img123/5439/14060612097cu.th.jpg[/img]
I'm using shapeshifter, no way I change the theme (or use the original one), the problem is still there.
I repaired permissions and all that stuff with Onyx, same thing
any idea?¿
Mini 1.42 80 Gb HD + EZ Mini 250 Gb / 1gb RAM/Bt/Ap/Sd Mac OS X (10.4.6) Apple BT Keyboard & NGS "Snake" BT Mouse + Samsung 913v + M-Audio Mobile Pre

I don't remember when it showed, but in any case, it's been a long time I use shapeshifter, and I don't remember having this problem.
So long, I have disabled shapeshifter, logged into a newly created account, moved non-essential fonts, cleared font cache... the problem remains.
I have made some extra few caps to explain better:
When I press cmd+tab, all open apps show on top
When selecting the first app (starting from the left), you can notice de name of the app is "slightly" shifted to the left.
This "sums" for each app, so at the third o fourth, looks like this:
If you have 7-8 open apps, the last one selected has no more the text inside the grey spot
And this is how it looks (yeaks)
Hope it's explained better....

Screen Sharing and CMD+Tab

Hi,
yes, my problem is solved. CMD+Tab now works within the screen you are sharing!
But, now of course, there's another issue. How to leave the shared screen using the keyboard? Meaning, how can I switch controls back to my own Mac using the keyboard.
Using the mouse works! But as a geek, I often prefer the keyboard.
Regards,
Roger

Before the cmd-tab was sent through to the remote computer I installed a control panel called liteswitch X which allows you to map alt-tab to switch apps. If installed on main computer, you could probably switch away from the screen sharing window with an alt-tab. However, I would really like to switch off the cmd-tab being sent to remote and the fix for ARD 3.3 (defaults write com.apple.RemoteDesktop DoNotSendSystemKeys -bool YES) does NOT work for me.
anyone ?

CMD Tab not switching to apps in different Spaces

This has been a problem in the past and looks like it's still lingering in Mavericks. Yes I do have the Preferences option set btw
I think it seems to be triggered for me when disconnecting my external monitor (connected via Thunderolt aka MiniDisplayPort to DisplayPort cable). So once I'm using the laptop screen only then CMD+Tab doesn't switch to the correct Space. Not sure if it's when I disconnect when my MBP is sleeping or awake, something else I can test I guess..
Anyone else still getting this, and in the same situation re ext screen?
killall Dock makes it work again though.

Unfortunately there doesn't seem to be a way to do that, or at least in my testing I can't make that happen.

Cmd-TAB is not working in 10.9

Hi,
since Mavericks the application switcher is not working correct. When I switch to an other application using cmd-TAB the menue of the other application is shown, but no windows of this application will be shown. In older versions of OS X the app switching via cmd-TAB was no problem.
Is ist possible to bring back the old behavior of the shortcut cmd-TAB?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in 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.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec sh
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that takes administrator privileges.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Dear all, I have a MacBook Pro bought in April 2011. Last April, it got stuck while the wheel was spinning and I had to force it shut. That cost me my hard drive. Now, it's stuck again. I tried esc, cmd tab, moving the trackpad on the apple, but no. HELP!

Dear John,
thank you for your prompt reply. After I sent the email, I left the wheel spinning to see if it would eventually stop. It didn't, but after a while the screen turned blue, so I decided to switch everything off with a forced shut-down. I could not restart with the OS DVDs because I am currently away from home, but fortunately everything was more or less fine after restarting. It then got stuck again, I forced it shut again, restarted again, and now it seem to work but I won't overdo it and will switch off smoothly after writing this (unless it gets stuck again). Last April I have replaced the HD, so it's now just under 6 months old. And, of course, since the crash occurred when I was abroad and had backed up just before I left, I have lost only a few days' work. Still, and I know this will make me hugely unpopular here, with my 5 previous laptops running on MS Windows I never had a problem. Which does not mean I loved the OS, or I would not have switched to Mac.
Anyway, and this is the main reason for this message, thank you very much again for your speedy intervention.

CMD + Tab and dock spotlights not working

I've noticed the CMD+TAB intermittently no longer shows the open applications. It's only showing Finder. I can have any application open and still just the finder. At the same time, the blue spotlights under open applications no longer work. A restart seems to fix it.
Any idea what's going on and what I need to do besides conintually restarting my machine?
Thanks,
Jeff

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. The Guest login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
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 Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Why is the CMD-TAB app switcher still unable to properly focus apps?

On my MacBook Pro running OSX Lion 10.7.5, and on previous versions of OSX, I've noticed a very strange defect in the way the graphical environment switches applications.
To reproduce the problem, I open three apps (it does not seem to matter what apps are opened). At least two of the apps are on the same mission control (previously space) desktop so that they overlap. When I use CMD-TAB to switch between the same two apps on different miss.ctl. desktops, very often, as in, about every other switch, the app I'm switching to is underneath another application's window. It fails to rise to the top of the stack.
It is not regular. That is, sometimes the switched-to window does rise to the top. About half the time, it does not. This makes the app switcher a capricious interruption when I'm programming. I used to use spaces 2D spacial layout to spread out my windows and avoid the buggy behavior, but Apple jettisoned that with Lion.
I don't know if this is a problem with OSX's GUI, the libraries, or with the way developers write applications, but it has been a long standing issue. Has anyone else experienced this? It seems like it should have been fixed by now.
Anyone have any clues or fixes ?

Never mind. Apparently a duplicate of other threads. Possible fix: update the defective OSX Lion to Mountain Lion.

When I open a new program in mountain lion it is not visible in the dock, nor can I select it with cmd-tab.

Any ideas? I'm on a MacBook Air.

I have the same problem as m.proudfoot. Defintiely a bug with the Dock. In addition, when I minimized applications, despite having the preference to minimize windows into the application icon, they would also start minimizing as windows to the right of the dock. I was able to fix it temporarily by restarting the dock. Go to the Terminal Application (in Utilities) and type the following: killall -KILL Dock
That will restart the dock and for me it worked, where all of a sudden three running applications appeared and the CMD + TAB starting working again. Give it a try to see if it helps at least until there is a 10.8.1.
As for what causes it, that I haven't figured out yet, but I have had it occur on 2 different machines, a MacMini and MacBook, both with Mountain Lion. So sure seems like a bug.

CMD+Tab Issues In Mountain Lion (consolidated)

I've seen CMD+Tab Mountain Lion issues myself and some others have posted online, so I'm consolidating them here:
CMD+Tab fails to show all running apps that are running (includes native OS apps such as iPhoto, Mail, etc.)
Pressing CMD+Tab does nothing (no pop-up), although the cursor does appear as if the command is partially being processed. (window prepping?)
CMD+Tabbing OUT of a full-screen application takes you to desktop, but then hides app icon from dock and CMD+Tab menu won't appear again... effectively leaving you stuck outside of the full-screen app (SC2). Only option is to go to activity monitor and kill process.
Interesting Side Note: I also use Alfred (CMD+Spacebar) for a shortcut/index app, and whenever CMD+Tab fails, Alfred also fails and I'm forced to manually used Spotlight to open apps. This suggests something could be tying up the CMD button and preventing it from executing combination key presses... maybe?
FIXES: The only solutions so far involve killing the processes of the perpetrating apps, i.e. finder, dock and any full-screen apps which caused the problem. Even doing so, the problem will manifest itself once again within a few hours.
Cheers!

I haven't tried experimenting with a guest user account as I solely use my admin account, but I'll play around a bit tonight. I only posted as it's manifested itself multiple times on my machine, no matter whether I sleep my computer, power nap it, restart it completely, etc. and it seems as though others have been experiencing similar issues:
https://discussions.apple.com/message/19236413#19236413
https://discussions.apple.com/message/19171533#19171533
https://discussions.apple.com/message/19106906#19106906
https://discussions.apple.com/message/19137798#19137798
It seems as though the problem may lie more with applications running but not displaying as if they're running, i.e. won't appear on dock, or if it's a native app, icon won't have indicator light, and also not available in cmd+tab menu.
Certainly odd behavior.

App switching (cmd-tab) and Expose stop working

This has happened to me several times in the last couple of days: Suddenly the cmd-tab command for switching applications stops working, as well as my active corners for Expose. No matter if I use the laptop's keyboard or an external one. After a restart everything works again. Any ideas?

I'm having the exact same problem. I think it may be somehow tied to the new update of itunes (9.0.1) because when I try to cmd+tab after open itunes it activates tabbing within the itunes fields.

Spaces / Firefox / CMD Tab

Hi @Apple
1) Even if i switch with CMD-Tab to Terminal in Spaces 1 and then back to Firefox, i had to click into Firefox, because it's not active.
2) If i have more terminal windows open and switched back to terminal in antother Spaces Window the last active terminal is now in background and another one has the focus.
3) Whish: Could you please give me the ability to change the effect when i switched between spaces. I whish the cube effect. It's so cool....

I am also experiencing all these problems. 10.5 has some great features which I am really enjoying using, but I have to say I'm a little disappointed in Apple for releasing the system at this stage, it really is below the grade.
Command-tab will often switch me to the other app, but will not change from the current space to the space the app is in, let alone set the correct window focus. This is happening with many Leopard apps too, mail,, safari finder, not just third party.
Can't wait for 10.5.1, let's hope it fixes many of the bugs.

Cmd-tab does not bring up window

When you use command-tab (actually cntl-tab) in Windows, you can scroll through each active program and the active program you stop on displays the window of the active program even if you had minimized it previously. This is not true for the Mac operating systems. You can use cmd-tab, but the program you stop on--even though it is the active program--the window does not show if it has been minimized. You have to click on the icon in the dock.
Is there anyway you can re-launch the last active window of the active program without clicking on its icon in the dock? Is there a shortcut key combination that launches the window of an active program?

To my knowledge, no. I tend to avoid the problem by not minimizing windows. If I want to get to the desktop I use Mission Control's desktop function. I also use multiple desktops and assign programs to them.

Cmd tab graphics are corrupted! but why?

When I use cmd+tab to switch applications, I have been getting the following, for a few days now:
This is from a fresh start with no apps running. It still functions properly and when I release cmd to change app, the colours return to normal for the fade.
Does anyone have any idea what's going on?
Thanks!
Joe

This happened to me last night too.
I was also having problems with my iphoto thumbnails too though. But I'd been having this problem for a while. I rebuilt all my thumbnails, and restarted my computer.
After the restart, the cmd+tab icons got fixed!

Cmd-Tab behavior is inconsistent

Flipping between applications is simple using the Cmd-Tab key combination.
But I find that it's not consistent.
If for example I am using a web browser and want to check mail with the e-mail client, pressing Cmd-Tab (and repeating the Tab press as needed) brings up the e-mail application.
But if, after checking mail, I press Cmd-Tab once, I am not always returned to the web browser.
Sometimes when I press Cmd-Tab, the order of apps displayed across the screen is not the order I've recently visited them. For example, the most recent app I visited might be 3rd or 4th, as displayed.
This has puzzled me for a long time. Why does OS X not consistently take me back to the previously-used application with one press of Cmd-Tab? It frequently does, but not always. The order is random.
This has persisted across both Leopard & Snow Leopard.
Am I alone in this experience? Ideas?
Thanks.

I haven't noticed that.
Can you try it in another user account?
That will help narrow down the problem to your account. I'm not sure where to go from there, but it's a start.
