Dock and command tab function

my dock mysteriously has disappeared and will not show up on the bottom of my screen. my command tab function to move between applications does not work either. i just installed the latest update for mac os but it hasn't fixed the problem. any advice?

Start by running the two basic checks provided by Disk Utility's "First Aid" tab to make sure the file system & system permissions are OK. (You can ignore SUID warnings in the permissions check.)
If that doesn't turn up anything, try creating a new user account for testing purposes. If the problem goes away in the new account on its first login, it implies some user preference file is corrupted or an incompatible or corrupted login item is present in your normal account.
If that turns up nothing, try Mac OS X: starting up in Safe Mode, then log into your normal account. If the problem disappears it implies something mentioned here is or was the culprit. (Some problems are fixed by a safe boot, others require more work.)
If any of these steps reveals a problem, don't go to the next one until it is resolved. If you need more help determining what to do about any revealed problem, please post a description of it & list any steps you have already taken that had no effect. If you can resolve the problem, please post a description of what you did as well. (Others will benefit from your experience, good or bad.)

Open applications not appearing in dock or command-tab.

I am using 10.9.5 on a Macbook Air and I've noticed recently that open applications don't display icons in the dock. Command-Tab also doesn't show the icons of all open applications either. This seems to be recently occurring. It's quite frustrating switching between applications when command-tab doesn't show the open application icons nor are the icons of open apps displayed in the dock. Any ideas are appreciated.
Thank You

Open the Terminal in the Utilities folder. At the prompt paste the following:
killall Dock
Press RETURN. See if that helps.

Filemaker Pro 6 Command Tab function in OS X

Hi ~
I'm operating on two computers. I have OS 9 on one and OS X on the other. I have Filemaker Pro 6 operating on both units.
On the OS 9 computer, I can use the command tab function to go back and forth between files in the program. On the OS X machine, command tab switches programs (between Filemaker, Safari, iTunes, or whatever else I have running).
Do you know how I can use the command tab function in OS X and stay within my Filemaker program?
Thanks!
Mac OS X (10.3.9)

Trying the L7700 Series software didn't help me. I tried several things and eventually got it working again by doing the following (it would stall out after printing a couple inches of the 1st page of a print job). I'm not sure if all of the steps were necessary, but I believe so. 1) I "Restored" the driver for the K550 from my Time Maching backup, by opening the window in User--->Library--->Printers (search for that Printers folder if Library is hidden in your User folder), going back a few months to find a driver that hopefully would work.(I could have also found a driver from my Mac OS 10.6 hard disk partition) 2) I added the K550 printer (connected via USB) in System Preferences---->Print & Scan, by clicking on the + button at the bottom of the list of current printers (I have a big list). It should show up in the list of connected or networked printers. 3) Select HP OfficeJet Pro K550 4) Select "Print Using: Select Printer Software 5) Look for and select the name of the HP Officejet Pro K550 dirver in the list of printer drivers (name can be typed in the Filter search field). Click Ok, which brings you back to the "Add Printer" window. Then click Add.
Notes: 1) I also restarted once after I restored the driver from my Time Machine backup. 2) I had first deleted the Officejet Pro K550 printer from my list of printers when this problem first cropped up, thinking I would just reinstall it as I would have done before Lion, with the problem hopefully fixed. I then (re-Adding the K550 before trying the above step) let Lion attempt several times to download the driver from Apple's web site, but it couldn't find the 6 year old printer's driver, which is why I had to resort to this.

How to make a backup of your stuff? and Command+tab question

First of all, is there an alternative to using a different Command+tab button? OR the F3 button to switch between windows? A lot of times I have more than ONE safari window open and I want to Command tab but Command+tab won't show the OTHER safari sites open. I use the F3 button also but is there another way to ALT+tab to DIFFERENT safari/firefox windows like on the Windows OS?
I was just wondering if IN TIME, Mac's will start running slower (like PC's) as you put more programs in. I know from experience, even by just staying on trusted sites, in about 2+ years your windows vista/7 will be a little slower. How do I reformat a Mac (factory reset) and besides backing everything up on a DVD, is there a way to backup my files?
Sorry for these nub questions, I only had this for like a month xD

Welcome to the Mac world!
Mac OS let's you fully customize the keystrokes which you can quickly move between the windows you want. You will find these settings under System Preferences and Expose & Spaces under the personal area.
When you are in here, you can assign a different keys, or secondary key, to active the show all windows (what you are currently using as F3). Under the All Windows selection, you will see the default set to F3. Here you can change it if you would like, say assigning the right or left shift key to open the show all windows feature. In the box to the right which should be empty, you can even assign extra mouse keys (assuming you use an external mouse) to do the exact same thing, which I find makes your work-flow much easier. Play around with the mouse settings to get what you like (I use my mouse to show all windows when I press the scroll wheel). Hopefully this will be a sufficient solution to your needs. Have a look here for more keyboard shortcuts: http://support.apple.com/kb/HT1343
Regarding your second question, you will find that Mac's do not fall failure to the typical 'OS rot' that you see when using Windows in just a short year or two. The same goes for keeping your computer on for long periods. Where Windows will be noticeably sluggish after even a day or two of continuous use, Mac's can have an uptime of weeks without a drop in performance (a buddy of mine usually only restarts once a month unless the power flashes). You will likely only need to re-install the OS if something happens to the computer and it no longer functions properly. In this case, I recommend using Apple's build in Time Machine application (http://support.apple.com/kb/HT1427) however you will require an external hard drive. Time Machine takes a backup of your computer whenever you ask it and if you have to re-install the OS, it will restore everything to it's previous state.
Hope this helps!

Screen sharing and "command tab"

Hi,
is there a way to "command tab" within a Screen sharing screen.
When I use "command tab", it's doing this on the host, and not on the remote machine...
Or is there another way to jump from application to application?
Cheers,
Roger

Screen Sharing Key Mappings: Expose and Command-Tab?

I am using Screen Sharing successfully and loving it - except that command keys work on my local machine instead of the remote machine. How do I get the Expose keys, like F9 and F10, and/or the Command-Tab keys to work on the remote machine?
Help?

I never received an answer to this. I'm marking it as 'answered' only to close it out.

Type input and command key functions don't work

I have regularly been experiencing problems with the type cursor not moving and not inputing type while using the keyboard. Also while this occurs command key shortcuts and the force quit dialog box won't appear on the screen after pressing the command, option and escape keys. The only temporary solution I have at the moment is choosing restart from the Apple menu.
Any suggestions or help with this would be appreciated!
iMac Intel Mac OS X (10.4.4)

You might try repair and maintenance, which Dr. Smoke goes into detail here:
http://www.thexlab.com/faqs/faqs.html
I've had keyboard problems that I fixed by running repairs.
You could also have a bad keyboard. If it's a non-Apple keyboard make sure you have the most up to date software for it. If you happen to have a spare keyboard plug that in and see if it happens with a different one.

Dock not working; command-tab switch between programs not working

The Dock does not work. I have restarted (although the computer will not restart under "Restart", getting stuck at the last part, and needs to be restarted manually). When I change Dock preferences it reverts back to default settings. If I am lucky, the dock will appear and then disappear (poof) without having functioned.
The command tab function for switching between programs stopped working also.
The individual programs work, but I have to go to recent items to switch programs.
Further, I have two Previews open (with different documents in each) even though I have only one Preview program.
A whole lot of bizarre things that may be connected? I would appreciate any help.

You could try removing the .plist file again, but this time, try also removing the com.apple.dock.db file. Then log out and log in again.
Also, it seems as if many people are having similar problems. See [this thread|http://discussions.apple.com/thread.jspa?messageID=9126119].
So, does the problem persist with another user account?
If it were my machine, the next thing I'd try is downloading the combo updater from Apple's website and reinstalling it. 10.5.6 is available [here|http://support.apple.com/downloads/MacOS_X_10-5-6_ComboUpdate].

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.

Command - Tab shortcut not working

My command - tab shortcut stops working after a random period of time and I have to restart my MacBook to get it working again. Any idea what could be causing this keyboard shortcut to fail? I tried killing and re-running the Dock but that does not fix it. A refuse to reboot my Mac everytime it happens (this is not Windows...) Any ideas on what might be causing the problem?

Actually I just researched this further and found a solution here:
http://discussions.apple.com/thread.jspa?threadID=1830738&tstart=0
+Open the activity monitor and look for something like the "ScreenSaverEngine" - the process should be marked as "not responding" (written in red)+
+End this process and Command+Tab and other shortcuts will work again!+

Command + Tab is not working

Starting today, the Command + Tab function is not working (this usually allows you to switch to another application with ease). I have tried changing the settings under "System Preferences," "Keyboard and Mouse," "Keyboard Shortcuts," however I have had no luck in doing so. When I click command + tab, all it does is switch from one text box to another on the same page, for example, it would switch from wherever I am on the page to the "Google" search box in the top right corner. If anybody could please help that would be great. Thank you so much.

Hi Kelbertou, and a warm welcome to the forums!
If you're using Safari check Safari>Preferences>Advanced to see if you have Press Tab to Highlight each Item on a Web Page checked.
Have you tried the other Command key+TAB?
If that doesn't help, I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.

Command + Tab - Some Apps Not Showing

I am noticing that certain applications are not shown when I use the (command + tab) function including Safari and others. This seems to have just happened all of a sudden and not sure why I did to cause this. I'm using OS Lion on a new MacMini. Any suggestions?

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 disabled

Hey i installed Yosemite and Command-Tab ( to cycle forward and backward through your open applications) is disabled. How can i enable it?
regards

Is it disabled in all user accounts, or just the one?
If you boot into Safe Mode, is it disabled there, too?

I have what looks like a second dock and a second command-tab window?

In my house we've got two macs using the wi-fi, a Mac Pro late 2013 running Yosemite and a Mac Mini also running Yosemite. What's strange is sometimes I get what looks like a second dock with only one icon, Chrome (my default browser). The Chrome icon has a little circle with a monitor above it. When I command-tab, that same icon is in a second command-tab box, and it's there even when Chrome is closed. I can't figure out how to make these things go away. Here are pictures to show what I'm talking about:
and the tab-box:
Thanks!

Are you using continuity/hand-off?
I am not using it myself but I have seen son presentations where the "second" dock represents an application running on your iPhone where your current task can resumed by using that feature
