Horizontal bar showing desktop bottom of screen

I clicked or tapped something on my doc, now a 1 inch horizontal bar runs along bottom of screen showing desktop

I have no clue what that means! Lol.... Sorry. I did remove "dock from view", I have restarted the computer. I forgot how to take a screen snapshot, but again, just a horizontal bar along bottom, showing desktop. Dock, if visible sits on top of it, if I go to "full screen" bottom showing desktop disappears.
Again, when I tapped with two fingers, or right clicked or tapped with one finger....cannot replicate it, it just appeared pushing whatever window I have open up an inch and showing my desktop.

A permanent horizontal line has appeared on my screen and will not go away. How do I get rid of it?

A permanent horizontal line has appeared on my screen and I cannot seem to get rid of it. Any suggestions?

You have the technicians at an Apple store genius bar examine your MBA and determine the cause and possible remedy. Make an appointment.
Ciao.
It is probably a GPU or display issue.

Try the standard fixes:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod
If you still have the problem that indicates that you have a hardware porblem and an appointment at the Genius Bar of an Apple store.

How to change the order of users in appearance of login screen?

Hello!
Because we often switch to a user,
which is listed last in login screen,
we want move them to the second place.
How to change the order of users in appearance of login screen?
Thank you for a tip
Erhy

The order users show up on the login screen is the way they are ordered under the
C:/Users directory. This is usually alphabetical, AFAIK there is no other way to change the order other than to change the username to something that starts with a letter that will be higher alphabetically.

That number is for an apple server in the UK that is used for iMessage activation. A hidden SMS is snet to that number when you turn iMessage on and is used to verify your phone number. I suggest you turn iMessage off. In settings/phone turn on dial assist. Check with your carrier to see if you can send an international SMS as you end that possibility to activate iMessage. Rest your phone (Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).) then turn iMessage back on.

When I launch a video from Finder the video is not visible, it's like it's playing on an extended desktop but I can't see the other screen - what is going on?

Hi Dan - I'm not sure I know what you mean by 'kick in Expose', can you please explain?
It's a weird one as it doesn't happen all the time. Could it have anything to do with running Apple TV and the MacBook 'thinking' there is another display (extended desktop) and playing the video there?

IPod Touch Graphics Weirdness - Status Bar mirrored at bottom of screen!!!

Okay, this is VERY weird and I have no idea what's going on - This morning when I woke up, I grabbed my trusty iPod Touch (4th Gen, 32GB with iOS 5) to check my calendar and noticed that the Status Bar (if I'm calling it the right thing - the white bar at the very top of the screen that shows the time, battery charge, WiFi signal,etc) was not only at the top - but also at the BOTTOM of the screen too!
The mirrored Status Bar has the correct time and battery life as the top and the time updates just as it should. I can also see the lock icon when I first turn it on. However, to the extreme left the bottom bar is sort of "washed out" and is so white that I can't make out the word "iPod" that shows on the top bar. In fact, it's also sort of translucent as I can see the dock, icon name and part of my wallpaper behind/thru it! I also just realized something else weird - if I pull down the Notifications panel, I can see the notification panel sort of "scrolling" thru the bottom Status Bar!!! I hope I'm explaining this well enough - but it's like..I dunno, like the ideo memory for the top of the screen is being mirrored over the bottom of the screen too - I can see what should be there as well, it;s like it's overlayed or something. The Notification panel is especially weird since it totally obsured the top status bar as it's being pulled down - and this is exactly what the bottom status bar area shows me - what's in the section in the top bar is prescisely what is showing in the bottom bar section!!!!
It stays displayed along the bottom no matter what app I'm in, even a full screen video, game, lock screen, etc; nor does it disappear when rotating to landscape mode - it still stays in the exact same place (tho in landscape it's now on the right side as it were). I have soft reset, synched, etc but it wil not go away. As I said, I deleted all recently installed packages, but I didn't install anything the night before (remember I just found it this way this morning) - i.e. I wasn't doing anything weird or experimental or anything remotely like that with my beloved little iPod (never JailBroken it or any of that stuff - am happy as it is and never been tempted to do anything like that to it). I also have never used any of the AV Out cables or whatever they are called that allow you to mirror an iPod screen on a TV or monitor or whatever - never used anything but the sync cable (now at my sisters), my Belkin charge auto charge cable, and that's it (I'm mentioning all this since I see other people asking this sort of thing for other problems when I was trying to find anyone else experiencing/ed this issue).
I have not tried a factory restore yet, and wanted to post here before I go that route to see if this is maybe something Apple has seen before and can offer a quick and easy fix. Otherwise I'm guessing a hard/factory reset is the only way to go - I'm a bit worried about this since (of course) my sync cable is no longer here - gave it to my sister the last time she was in town and have just been using my charge cable (no sync capabilities, just power) since I don't really need it with iOS5's wonderful WiFi Sync. I do use iCloud - but if I hard reset/factory reset, will iCloud restore the synching info so I can sync all my apps and music & videos back via iTunes from my Laptop, or will I need to buy another sync cable? IF factory reset is the only way, please let me know (anyone that knows!) what I'm in for in regards to restoring from iCloud if anyone here is experienced with that. I know my non-iTunes music and videos are not backed up in the Cloud, but as long as it restores the ability to sync wirelessly with iTunes on my Laptop that's fine. Asuming, of course, that a factory reset will even fix this Status Bar oddity - I'm really afraid it means my little iPod's internal board is going fry-happy or something awful like that. :-(
I tried taking some screen snapshots (home + power off) to post, however the camera roll just displays a standard beautiful looking screen, no double bar - not sure what that indicates. However after some fiddling and emailng to myself, I do have a couple pics posted below. I apologize for the lack of quality - I took them - and don't laugh - with my Android Phone (yes, I have every intention of upgrading to an iPhone 4S as soon as I can - having a bit of enforced financial conservatism going on at the present unfortunately - which is one of the main reasons I'm so worried my beloved iPod Touch 4 is having issues as it's either very close to warranty expriration and can't afford another right now, and really don't want to have to rely on my Android Phone for everything I do on my iPod Touch - there truly is no comparison!).
If anyone has any ideas or has seen something similar please let me know! I did search the Apple forums prior to posting this, and even googled the web but could find nothing like this ever happening to anyone else. I absolutely love my iPod Touch and would be uterly lost without it, so I'm hoping with all my might that this isn't some sign of a bad board or something in my beloved little beautiful iPod Touch!
Thanks in advance for any assistance, suggestions, etc!!!

I understand the various methods - I was just worried because I've never restored via iCloud - from the limited experience I've had thus far, I'm impressed! But of course if Apple does it, it's going to be the best experience possible! :-)
And as you may have guessed from my now having iCloud restore experience, it is due to me going ahead and trying a reset to factory settings/wiping it clean. And unfortunately - the bottom bar is STILL THERE! <much argghhing! and %^$#@*&^%$'ing loudly>
I did try wiping it a couple of times, but no joy. At this point, I'm guessing this means there's something majorly wrong with the graphics subsystem and/or main board? It's not a screen issue as it's working fine - in fact it's working double-time displaying two things at once - dimensional transcendentalists take note! <grin>
So unless anyone else has some fantastically bright ideas, I'm guessing this means I need to call Apple next? I'm guessing one of these pages has the appropriate contact info - I'm just not at all looking forward to being without my favorite gadget in the history of gadgetdom (and as you can tell from my username, I've been a fan of Apple Gadgets for quite awhile now!).
Anyone know if Apple offers any advanced replacement options? Or if there's anyway to tell if my Touch is stil under warranty? I can't remember the exact purchase date but probably coming up very soon - have they been out a year? Sorry if thee questions are silly, as I said, I'm a newbie to Apple Support - first Apple product I've ever owned that broke!
Thanks for any info for anyone coming in late to the fun, and/or for any tips on who/what to call and ask about.
Wish me luck! :-0

"Other-" appearing on login screen

Hi
I've got a MacBook Pro mid 2012 running OS X 10.8.5. I was running some commands about the root user on Terminal and suddenly I changed the password of the root user using these commands:
sudo su
Password:*******
passwd
& now I see another thing on the login screen named "Other..." which is the root user(Admin) . And its password is the password that I changed using Terminal.(It is the login part for the root user)
I want to get rid of that, is it possible?
I just wanted to remove it using system preferences but it doesn't appear on that part(Users & groups)!
I think it would be possible to delete it using the Terminal.

Disable Root User if enabled.

Login Icon and shutdown icon not appearing on login screen

I don't know if it is just coincidence but I have had two instances where the login icon and the shutdown icon are not appearing on the login screen and the login screen is not "live" after I had installed an HP officejet 8600 printer on my W700ds to run through the network and another computer last night. The first time it happened last night I wasn't sure what to do so I held the power button until shutdown and when it rebooted and the RAID1 had to verify. This morning when it happened again I was a little fresher and put it into hibernation - Fn-F12 - and when I woke it it acted normally. I have just had a new mainboard installed on 1/15/2013 and a new processor installed on 1/22/2013 to cure other problems and have used it at least one full day after rebuilding without a problem before this started.

Hi, Geophyte1
I did some research and found this document from Microsoft that might shed some light on your issue. According to Microsoft, this error is normally the result of graphics issues, but can also stem from RAM issues. There are two methods posted by Naman R, a moderator, that may be able to help you.
Best of luck. Let me know how it goes,
Adam

Network users not appearing on login screen

Hi all. I have just started setting up Lion Server for my household however have a slight issue with allowing network users to logon to devices. If I allow usernames and passwords to be typed in manually then network users can login, however if I want to have them show up as users on the login screen it doesn't work.
Is there a way for network users to be visible on the login screen at all times please? There are only two network users in my house.
Thanks,
Jordan

See my reply here https://discussions.apple.com/message/16280642 where I previously described how to do this.You will need Workgroup Manager installed for Lion if you have not already downloaded and installed this. You can get it here http://support.apple.com/kb/DL1419

On the iMac user account login screen, what does the checkmark mean?

On my iMac, I have 3 user accounts. Sometimes I have noticed that next to 1 of the 3 account names that I will sometimes see a small white check mark in a red circle. What does this mean?

I just received the same login for the first time in a while. I had left my MacBook Pro asleep for several days and then turned it back on and the wakeup/login screen presented a similar red circle with a white check mark inside. Did you find an answer? I created a new post today to see if anyone has had anything similar, not sure if it's firevault or not confirming id...

It sounds like you are interested in "My Photo Stream" with iCloud which syncs your pictures between devices. Please see if this is what you need.

You may need to try this More than Once...
Some users have reported as many as 8 or 9 attempts were necessary before success.
Be sure to Follow ALL the Steps...
But... if the Device has been Modified... this will Not necessarily work.
