Upgrade to Yosemite cause weird dual screen mirror on login only

I just upgraded (and also tried a fresh install to an external drive with the same results) to Yosemite from Mavericks. When I start the MPB I get the apple and the thermometer (white fill in bar) every time I reboot after a complete shutdown. Then, the login screen is mirrored on the external monitor and LCD in a non wide screen resolution (looks like 1024x768). After I log in it looks ok but this doesn't happen with Mavericks. I just got this MBP Jan 2014. Any help would be greatly appreciated. I also tried cmd-opt-p-r.

A friend just told me the apple/thermometer is normal for Yosemite so ignore that part.

Not having the Screen Share icon sounds like they were a the Participant level of permissions in the room, and needed to be promoted up to Presenter or Host to be able to share their screen.
Here is a screen shot, with the Participant on the left and a Host/Presenter on the right:

Yosemite causing slow screen refresh using TOS

Problem description:
I use my iMac for trading with a java script app called ‘ThinkOrSwim’. It was working fine with Mavericks then I upgraded to Yosemite. Problems continue even when upgrading my RAM from 4GB to 16GB. Overtime the Screen refreshes get really slow after using the ‘TOS’ Platform for 2-3 hours. Have to do a SMC Reset to be able to use the ‘TOS’ platform once it becomes too unbearable to work with it.

I just want to add that to further this improvement, I also disabled stat menus, and anything on the menu bar that caused the screen to refresh. I disabled transparency, the genie effect, and forced quit the window server on the activity monitor, and disabled the dashboard and the system preference "displays have separate spaces" - which required a re-login.
I also left the auto-switching on the nergey preferences to the GPU to always use the 330m, rather than the intel hd card.
Basically, I disabled anything that made any extra load on the GPU.

After I upgraded to yosemite my screen flickers with windows, very strange.

So, after I upgraded to Yosemite, in spurts, there are flickers of windows at random positions around the screen.
It doesn't seem to depend on what applications are running. However I'm usually running Safari, so perhaps it depends on Safari.
Let me describe what the picture below is:
I took an iPhone video of my computer screen, used VLC and slowed down the video to (really really) slow, and then took a screen snap shot during the flicker.
So, if you look at the weirdness, it is a ghost of the entire screen, but, obviously, not in the right place. These fickers can be frequent, like, "bididididi (pause) bidididid (pause)," or in frequent like, "bip (wait a very long time) bip (wait a very long time, perhaps hours)."
This never ever happened with Mountain lion.
About my mac says:
Is anyone else experiencing this problem?

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Black boot screen and startup manager on mid 2014 rMBP after upgrading to Yosemite

After upgrading to Yosemite I'm experiencing black booting process. Moreover, I noticed that the startup manager, which we access by holding the option key, has the black background too. I didn't like the Yosemite, so I downgraded back to Mavericks, but I still have the startup manager with the black background and the initial screen during the startup sound is black too, and after that the grey screen with the Apple logo comes up, which is typical for Mavericks. I want my startup manager to have the grey background as before. And also, before there was the grey screen during the startup sound, not the black one. How to revert all this to the previous state? I'm experiencing all this on my rMBP, 13-inch, mid-2014.
I want to revert because after downgrading back to Mavericks my rMBP started freezing terribly, especially on youtube, ebay and app store. And it's not just the web browsing, it's freezing when navigating in finder too. I know there are many experienced users here, so I hope that somebody can help me with this. Before upgrading to Yosemite my machine was running flawlessly.

After upgrading to Yosemite, I am unable to share screen with Macbook Pro

After upgrading to Yosemite 10.10 on a 2008 MacBook Pro I am unable to "Share Screen" using my authorized user account. It worked fine before I upgraded to Yosemite.
I can access "Share Screen" by "requesting permission", but of course this doesn't work unless I am sitting right by the MacBook Pro to give myself permission, which defeats my original purpose for using "Share Screen".
I attempted to add another authorized "Share Screen" user account, but was unable to access the list of add "Groups and Users" on the host MacBook Pro from the "Share Screen" dialog box. The dialog box pops up, when I press "+" to add another user, but the list of users fails to appear. I assume the list of authorized users for screen share has somehow become corrupt.
All other ways to access "sharing user" accounts appear to be working properly. I can add and remove other "sharing users" without problems. For example, I can add a new authorized "file share" user and share files without problems.
I ran Disk Utility in Recovery Mode and normal mode and corrected all errors, and user permissions on both machines. I also ran "resetpassword" from Terminal in Recovery Mode and "reset" user permissions. I am not an experienced Terminal or Recovery Mode user though.
I also tried turning the Firewall off, to no avail.
I am attempting to access "Screen Share" on the MacBook Pro via a Macbook Air 13" manufactured mid 2013 also with Yosemite 10.10, however, I also attempted with an older MacBook Air which experiences the same problem.

Thanks for the idea but it did not work, I do not know why it is asking me for a password which I never needed before for a guest to use the computer? I have tried everything and I do not know which password it wants? I do not see any option for a password for the guest account, to create one or delete one or modify it? Maybe this bug\problem will be addressed in a future update?

I think you are sailing in uncharted waters with those kind of modifications.
I am only guessing, but if you have not already done so, do a PRAM reset and then trash your FCP preferences.

My understanding is the Mac is doing a ram/hardware test during the grey screen, if the card you added had additional memory, then it is very likely the test will take longer - but I am no hardware expert.

Upgraded to Yosemite and can no longer remote into my work iMac through screen sharing- it is turned on in settings?

My screen sharing functionality did not show up in the dock with an updated icon. It had a question mark- shows my connections but nothing works, I did make sure screen sharing is on and also connected to VPN. Once I tried to launch screen sharing nothing happens. Such an elegant solution in Mavericks not does not work. Ugh. Help!

This is the post that got me set up- I too am running an older version at work vs. Yosemite. As soon as I followed is advice everything worked.

I believe the location of the "Screen Sharing" app has changed, which explains why if you had it in the dock it has been replaced by a ?
Don't forget you can launch screen sharing (once your VPN connection is up) by typing in the Safari destination slot vnc://remotemachinename:portnumber (omit the :port number if you are using the default VNC port, 5900). This should launch Screen Sharing and put its icon in the dock. You can drag the Screen Sharing icon to the left of your dock and it will hopefully remain there after you exit Screen Sharing, or you can right-click on the icon when it's running and select Options->Show in Finder to find out its new location and drag its icon to the permanent entries in your dock.
Hope this helps; worked for me.

Black screen flashing constantly recent upgrade to Yosemite

I upgraded to Yosemite yesterday on my brand new macbook pro with retina display and this morning i had some issues with my fonts so as i was looking in the library folder to try and find the font problem all of a sudden my screen went black and then started flashing every second to the normal screen and back to black. Now i can't even log in with out it constantly flashing black - can anyone help as i've no idea what i've done to it or how to resolve the issue because i can't get onto it!

I managed to solve mine by rebooting my mac in recovery mode (hold down cmd + R when you turn on) then reformatting and re-installing OX S Yosemite. Unfortunately it means loosing all your stuff but it's stopped the problem for me! Hope this helps.

Since upgrading to Yosemite my old email address is showing in the middle of my screen and I can't remove it.

Since upgrading to Yosemite on my iMac I have my old email showing in a small grey box in the middle of my screen. I don't know how to remove it.

The address has now gone - all I needed was another restart. But it did take two attempts. Thanks for your interest. Have also found that the iMac is slower at the moment. Goodness only knows what else I will find when I restart other progs.

Since upgrading to Yosemite, when I try to compose a new message, the window is wider than the screen and I can't adjust the width.

Ever since I upgraded to Yosemite on my MacBook Air, I cannot get the mail window to adjust to a size that fits my screen. It is wider than the screen size and although I can adjust the height, the adjustment arrows will not adjust the width. I am not having the same problem with my mac mini since I upgraded that computer. This is a pain because I spend most of my time on my air sending out e-mails to clients

Greetings kbug61,
It appears you are experiencing issues with window sizes and displays. Have you attempted to adjust your resolution at any point? That may be why the windows aren't managed properly. The following article may help you find a solution:
OS X Yosemite: Adjust your display’s resolution
Your display’s resolution determines the size of text and objects on your screen. By default, the resolution on your display is set to show the sharpest text and the most detailed images. While it’s best to use the default resolution, you can manually set the resolution to make text and objects appear larger on your screen, or adjust it to make text and objects appear smaller so you have more space on your screen.
Depending on how you adjust the resolution, some apps may not fit entirely on the screen. Using a scaled resolution may affect performance.
Set the resolution for your primary display
Choose Apple menu > System Preferences, click Displays, then click Display.
Select Scaled, then select one of the scaled resolution options.
Set the resolution for a connected display
If you have more than one display, additional resolution options are available.
After the display is connected, choose Apple menu > System Preferences, click Displays, then click Display.
Press the Option key while you click Scaled to see additional resolutions for the second display. Then select a scaled resolution option for the second display.
If you changed your display’s resolution and now there’s no picture
Connect multiple displays to your Mac
Set options for accessibility
Thank you for contributing to Apple Support Communities.
Best,

Upgrade to Yosemite 10.10.1 caused my Canon Pixma ip8500 printer to stop working. Canon no longer supporting this printer. Any solutions?

Upgrade to Yosemite 10.10.1 caused my Canon Pixma ip8500 printer to stop working. Canon no longer supporting this printer. Any solutions?

Hi
try this
resolve my printer problem.
with Yosemite, Apple have upgraded CUPS to 2.0, and CUPS work different. So you need to change one think in configuration.
open terminal, and write the following commands:
sudo sh -c 'echo "Sandboxing Relaxed" >> /etc/cups/cups-files.conf'
you asked for the password for superuser
sudo launchctl stop org.cups.cupsd
after this check in print queue if the printer is ready and not in pause mode.
The printer now should work, if the printer only print in B&W you need to change the configuration in CUPS web interface.
try http://localhost:631/ ; if you receive a error telling the web interface is disabled, type in terminal services the following
cupsctl WebInterface=yes
after this try again http://localhost:631/
after this choose in the web page "Adding Printers and Classes", bellow the CUPS for Administrators title.
in the new page, choose manage printers; after this choose your printer.
in the page of printer choose from the second combobox the option "set default options";
in the option page, change the color mode from monochrome to color, and save hitting the button "set default option", you be asked for a user and password with admin privileges.
After this your print is ok.
