Command-tab issue
I'm not sure if it's a feature, but sometimes I press Command+Tab and only the icons for apps in that space show. If I let go and try it again, I get the whole list of apps open system-wide.
I've done some searching but can't find any answers. I sthis a feature?
guitar4542 - My question wasn't how to get the app switcher up, thanks.
Carolyn - I can't see anything in there for switching with command-tab at all. The basic feature I know, but this whole switching between apps that are only in that space is something that seems to be new, since Leopard has Spaces and previous releases of OS X didn't.

Mac OS X 10.5 Finder issues - Application switching via Command-Tab
I have been having problems recently, when I would switch apps using command-tab, some applications don't show up. I haven't noticed this before, while using the integrated graphics card, but have noticed it since using the discreet card, related?
I'm on a dual 2.7 G5 and I'm having this same issue - so I don't think it's the graphics card... not sure. Anyone have solutions? Or the same issue?

Safari problem: when I switch back into safari from another application, the menu bar comes up but no tabs or windows. What's going on? Just started yesterday. I have found a workaround: when I Command Tab back to safari, I hit command T to open a new tab and Command W to close it, and my other tabs are visible.
I have tried shutting down, closing tabs, with no success. What's going on and how can I fix it?
Thanks,
Cindi B
PS: I'm not sure of the actual OS level, but I have not allowed it to upgrade to Maverick yet; concerned about it because of a few things I've read...A Safari extension or third party plugin may be causing the menu bar issue.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
As for which OS X is installed.
Click the Apple () menu top left in your screen. From the drop down menu click About This Mac.
The version is noted there.
v10.6 Snow Leopard v10.7 Lion v10.8 Mountain Lion
It's your choice whether or not to upgrade to Mavericks. If you decide to do this, make sure your Mac meets the requirements noted here. -
Command tab - app windows not at the forefront
I used to be able to speed through my apps, but now for some reason when I switch to another application, I have to click on the window in order to make it active (i.e. if I copy something from safari and command+tab to word to paste it, I can't just immediately follow it with the paste key combo). I don't know when this started up, but I think it may have been with the latest mountain lion update. Anyone else having this issue? Is there some setting I don't have setup right?

Command Tab not pulling up open windows from Dock
Sorry if this is covered elsewhere, though I have looked:
Using Command-Tab to invoke Application Switch is very helpful. However I have an issue with iCal and with AddressBook sometimes. If they have an open window, minimised to the dock, it does not jump up on switching. Other apps do; just switching with command-tab to that app pulls up the most recent window. With iCal/AddressBook, it switches to the app; but the window remains in the dock and needs a click before it jumps up. Which kind of negates the app-switch in the first place, if you need to follow through with a mouse-click as well.
A similar question was asked here:
http://discussions.apple.com/thread.jspa?messageID=1424140
Thanks for your help.
PowerMac G4 2x1G MDD; PB G4 1G Mac OS X (10.4.3)Alastair,
I believe that behavior can be attributed to any application with one minimized window. I get around that limitation by using the Hide feature. For example, just use the Address Book>Hide Address Book (⌘+H) command instead of Minimize (⌘+M). Using Apple + Tab will then open the Address Book application window as you would expect.
You can use the Keyboard to access a minimized window, but it is not convenient. (Control + F3) will give you access to the Dock. Then use the arrow keys to navigate to the Dock icon of your choice and hit enter. That action will open the application or window of your choice. Esc will cancel the keyboard action.

Spaces confusing safari windows (on multiple spaces using command-tab)
Wondering if this is happening to anyone else.
I love spaces but something is messed when using safari windows on multiple spaces. Say I have two safari windows open on two different spaces, after command-tabbing to another app when I try to command-tab back to safari it doesn't always go to my last safari window. That is to say that sometimes it goes to the other safari window, and sometimes it doesn't. It's super unpredictable.
Give it a try, open two safari windows on two different spaces and the command tab to another app and then command tab back to safari - and repeat... you'll find that it will just randomly go to the other window, and then back etc.
Can't think of anything more annoying in spaces... that's got to be a bug.
Anyways, let me know if it's happening to you.
Jay.same issue. i have multiple safari windows with multiple tabs on multiple spaces. let's say one space is a rails space; so it has some terminals, safaris, firefoxes, all perhaps with 2 or more tabs. command-tab does not necessarily go back to the window of the app i was just in. whether it's safari or firefox or whatever. this is horribly un-intuitive. come on apple. that's like your thing, right?

Command, Tab option not showing all open applications
Hi,
Just upgraded to Mountain Lion and now when using the combination of Command+TAB not all open applications are displayed.
This seems like a bug or am I missing somethingI want to add to list as having same issue... Even core Apple programs not showing up (Safari, iPhoto) in Command Tab. But Mail, iCal do show up in Command + Tab. Also noticed that only some applications "minimize window into the application icon", while others get minimized to bottom right of Dock. Additionally no "Show indicator lights for open application" appears for those missing programs. I attempted to select-unselect both of those in the Preferences -> Dock options and restart a few times, with no success.
The same programs missing from Command + Tab are also missing a graphic icon in Dashboard view (only Application Name appears).
Issue is new to OS X Mountion Lion, I did not have that problem before. -
Tab key all of a sudden is Command-Tab in client windows...
All of a sudden, whenever I use the Tab key when connected to any client, it acts as Command - Tab. For example, when I attempt to tab to another field in some form and press Tab, it brings up the open applications thing and scrolls through them. If I then press any other key, it acts as Command - "(whatever key I just typed)". If I press a k key, it acts as command - k. This only happens after pressing the tab key.
So basically, after pressing the tab key, all subsequent key presses act as if the command key is also being held down.
I have to disconnect and re-connect to that client to get it to stop doing that.
I do not see anything in the prefs to help with this. I did see one other forum topic about this but there was no fix posted. Sticky keys show nothing strange is going on with my keyboard. This is definetly an ARD issue. All local tab and command keys work as expected.
Thank you very much for any info regarding this.I found the issue... I use TypeItForMe, and part of the instructions for typeitforme is to turn on "Enable access for assistive devices" in Universal Access preferences. When this is turned on, in ARD when connected to a users machine and controlling it, if the Tab key is pressed all subsequent key presses act as if the Command key is also pressed.
I have turned off "Enable access for assistive devices" and now ARD behaves normally. However, I am unable to use TypeItForMe the way it's supposed to work.
So, not sure if it's a bug or normal behavior, but sure wish it wouldn't do that... -
Command tab - window doesn't switch
I use Command+tab to switch between windows. But many a times the window doesn't switch to, rather I get the options at the toolbar.
This is exactly the problem reported here: https://discussions.apple.com/thread/3458920?start=0&tstart=0
How can I resolve this issue?Just found out that FoxTab 1.4.2b is causing this problem. Solution? Disable it.

Apple (command) + tab crashes Safari
Recently, while tabbing through forms in Safari, pressing the key combination 'command' ⌘+ 'tab' to go backward in a form has caused Safari to crash.
It actually just gets the spinning beach ball of death and become completely unresponsive. I have to force quit Safari and relaunch.
Any ideas on this? Anyone else seen this problem?
Basically, it's the same issue as this from 2004. Hmm.
"http://www.donnunn.com/spiel/2004/02/safari12crash.html."
G5 20" iMac
OS 10.4.8
Safari 2.0.4 w/ Saft 8.3.11 and AcidSearch 0.62But the tab problem persists, even if i user other accounts.
In which case it might either be an application problem, or a shared plug-in issue. Look in 'HD/Library/Internet Plug-ins/' for possible culprits and if everything seems to be in order there, try reinstalling Safari from your Tiger DVD.

Pressing Command+Tab no longer 'switches' among open apps
i press the Command+ Tab keys and I can see all open apps. but when I switch among these open apps....nothing happens. In other words, the window of the app I select does not show. I used to be able to 'switch' among them. Why no longer works?
Thanks for your suggestion.
I'm a fairly seasoned Mac user (going back to Mac Plus in 1987) and have tried my usual 'bag of tricks' to resolve this issue. However, nothing works including comments from CNET on deleting some prefs. What did work is my starting up from a week old clone of my internal hard drive stored on an external disk. The external worked flawlessly using the app switcher. So, something happened in the past week. It could be the newest update to iTunes or a Mac 'security' update. I just don't know. What I'm going to do is sit on the fence like a bird and watch the community. Others are having this issue and eventually Apple will figure out what is going on and resolve it with yet another update.
Or....worst case scenario, since the problem is not that serious, I'll wait a month or two for Lion and solve it with an install of a totally new system. -
Command-tab can't call finder anymore
Hi,
I really have a weired problem with finder since yesterday:
I try to choose the Finder using Command-tab. The result is that I see the finder menus on top of the screen, but none of the windows appear, which is really annoying. I usually recover the finder windows by pressing F9 and then click on them, but this is an additional step which slows down work.
Does anybody know how to solve this?
GernotA good place to start is to make sure your computer is in generally good condition by verifying your drive and repairing permissions.
[Resolve startup issues and perform disk maintenance with Disk Utility and fsck|http://docs.info.apple.com/article.html?artnum=106214]

[Disk Utility's Repair Disk Permissions|http://docs.info.apple.com/article.html?artnum=25751]
From BDaqua:
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes."
If that doesn't clear things up try removing your Finder preferences file so a new one is created. Look for com.apple.finder.plist in your user folder > Library > Preferences (not the main level Library, the one in your user directory/folder). Move this file onto the desktop or someplace other than in that folder. Restart your computer. If that works, fine, but you may have to reset some Finder preferences. If it doesn't you can move it back into the folder (an new one will have been created but you can replace it) in order to restore previous settings. -

Command Tab Bug with Screen share
I often screen share to PC while working, After about an hour, the command tab function will fail. Closing the screen share will solve the issue, but its annoying that it fails in the first place. Any ideas on how to solve this little bug?
can't get the exact behaviour, but my Finder sometimes requires two presses of Apple N before a new window will appear. Also, sometimes even after launching the Terminal, focus is not given to Terminal, instead it remains with the Finder. Clicking on the Terminal window doesn't switch to Terminal, as expected. There is no way to get the focus to be the app in the foreground. I have to control click it in the dock and quit. note that it hasn't crashed (no force quit option), it simply refuses to focus.

MacBook Pro UI freeze on command-tab
I originally posted this elsewhere, but the thread was PowerBook specific. I'll retry here.
Occasionally - very rarely, maybe once a month, at worst twice in the same day - my MacBook Pro GUI freezes when I switch applications with command-tab.
Symptoms:
* the switch icons view remains visible
* the cursor moves
* no key combination will work (including cmd-alt-esc)
* the laptop remains accessible through ssh, and no particular process seems suspicious (no high load)
Facts:
* I think this usually happens under heavy load (Java compilation, multiple browser windows, etc.), so it could be a heat issue. Then again, this has happened even when a fan-cooled base was in use.
* It happens only when I hit cmd-tab
* This same laptop was earlier used by a colleague; he never had the problem. This would indicate a software issue. The pieces of software I run that are different from his are most likely Quicksilver, Skype, and Firefox, and possibly some Dashboard widgets. I haven't been able to eliminate any of these.
* Typical pattern of use: the laptop is almost always on; it sleeps only when I travel. I typically restart the laptop only after an update that requires it.
Equipment:
* Here's the basic hardware overview:
Machine Name: MacBook Pro 15"
Machine Model: MacBookPro1,1
Processor Name: Intel Core Duo
Processor Speed: 2.16 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP11.0055.B08
SMC Version: 1.2f10
Serial Number: SystemSerialNumb
Sudden Motion Sensor:
State: Enabled
(Note: this same phenomenon occurred on my previous PowerBook 15")
* For good measure, I'll list the processes running now (and typically). (Ouch, this is going to be long. I wish this forum supported attachments.)

So, the question...
...has anyone else ever encountered this, and is there a fix?
MacBook Pro Mac OS X (10.4.9)Hi ebudan, to me it looks like you've run out of RAM and had a lot of stuff swapped out by the OS (I'm guessing this based on your Firefox process having bloated to 250MB, your Safari to 300MB, and your Eclipse to somewhere over 200MB). Cmd-Tabbing in such a situation would then begin swapping pages back in from disk, which ties up all your disk IO; hence, the system becomes unresponsive answering disk IO requests but no process appears to be using up CPU time.
If you waited long enough, the system may become responsive enough for you to close an application or two, at which point you'd probably begin to see things return to normal.
One solution may be to add more RAM, although I suspect if you closed your browsers and re-opened them now and again (or simply opened fewer windows/tabs) you'd avoid this problem too.
Maybe you are looking for
