Since upgrading to yosemite my MacBook Pro want detect my external display

Since upgrading to yosemite my macbook pro won't detect my external display ?

Here's an Apple Discussions thread that might help. It suggests using Disk Utility to repair permissions to fix the following issue, which I just found on my system:
User differs on “private/var/db/displaypolicyd”; should be 0; user is 244.
Group differs on “private/var/db/displaypolicyd”; should be 0; group is 244.
If Repair Permissions doesn't do the trick (because it doesn't stick across sleep and restarts), helpful user "lplacencia" has provided some Terminal commands to patch up the files as needed. With any luck a 10.10.1 update will address this soon!
I haven't had a chance to test this fix yet, but I will do so later tonight. Meanwhile I can report that booting up in Safe Mode didn't make any difference for me. My system includes MacPorts (which includes some running services) so I might need to eliminate that factor, if Disk Utility doesn't help.
A total clean install would have to be my next step. (And I might try that anyway just to see if it's a problem in Yosemite generally.) It's not possible to download the Yosemite full installer from Apple through a public website, but you can save the installer and use it to re-install without having to download it again.

Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight etc. It was fine before the upgrade and I have all the system preference set to "never turn off"

Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight (cd's / recording etc. It was fine before the upgrade and I have all the system preference set to "never turn off" - Help !!!

Good advice from Linc Davis that should sort out your query i think...
However you dont want to set your MBP to never go to sleep...
Adjust reasonable sleep settings...
And the download an APP called caffiene...
When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
Simply click the cup... To toggle never sleep/sleep

Since upgrading to Yosemite my Macbook Pro makes me log on twice after shutting down or sleep

I upgraded to Yosemite a while ago. Since then I must enter my system password two times when I return from the shut down status or sleep status. What is causing this?

Do you have FileVault turned on? Based on what I've seen in the forum, that is causing the double login.

How do I get my Macbook Pro to detect an external display?

Hi there.
I just bought a new MacBook Pro today.
Everything about it is wonderful, except: When I plug an external display into the Thunderbolt port using a Minidisplay port to VGA adapter, it doesn't send a signal to the external monitor. The screen on my Macbook will go blue for a second, and then the windows freeze. The mouse will be movable for a bit (up to a minute), but nothing is clickable. Strangely, it seems as though it's functioning as if there were a second monitor (I can move the mouse off-screen as though it's going over to another display). But then the spinning rainbow wheel starts and never stops. If I unplug the Minidisplay port to VGA adapter, the Macbook will snap back into professional mode and everything works again.
If I try to boot the computer up with the Minidisplay port to VGA adapter already pluged in, it simply won't boot up (I get a gray screen with an apple and nothing more).
I tried using gfxCardStatus set to "discreet only" and I still have this problem. I tried to run a firmware update, but my comp seems to be entirely up-to-date already (just set it up today).
The monitor and adapter seem to be working fine, and function as an external display when pluged into the Mini-DVI port on my 2009 Macbook running Snow Leopard.
I guess my question is, what's causing this? Is this an adapter problem? Like, do I need a special adapter to use with a Thunderbolt port as opposed to the one I'm using which works when pluged into a Mini-DVI port?

The only thing that I can suggest is trying a different adapter - such as this one from Monoprice.
I don't know if that's the root of your problem, though. Does the external monitor have DVI? You could get a Thunderbolt to DVI adapter from Monoprice - here - and give that a shot.

The only observations are that the backup drive is deemed too small and the quite long list of diagnostic reports dated between Jan 18, 2015 (which I believe is the day I upgraded to Yosemite) & today the latest Yosemite update was installed on Jan 28, 2015
Any further assistance will be appreciated

After upgrading to Yosemite, my MacBook Pro now requires me to enter a password whenever I start up my computer. I want to eliminate this step and to go back to the ability to reboot and begin using without a login. How do I accomplish this?

Hightlight Login Option. This will bring up the window showing Automatic login.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time. Its completely random and i already checked all apps in use and its not from them.

Sounds like Notifications app.
Maybe some other app. In SystemPreferences->Users&Groups->LoginItems tab: remove all entries with the minus sign underneath. This will not uninstall anything, you have to start those apps by hand now. Restart.
Still there?
Yes: Restart again while holding the shift key, this will start the mac in SafeMode: only the necessary items are loaded to run.
Still there?
Yes: Make an etrecheck list and post it here.
No: Restart, put the items in the LoginItems back, one by one, restart after each entry, and you will find the "culprit"
Please report accordingly. I will be back in 24 hours.

Since upgrading to Lion, my MacBook Pro is super slow connecting to Wi-Fi. Not so with Daughter's Snow Leopard or Wife's Dell. Any ideas?

Since upgrading to Lion, my MacBook Pro is super slow connecting to Wi-Fi (seems to search forever). This is not the case with my Daughter's MacBook (still on Snow Leopard) or my Wife's Dell (Windows 7). Any ideas?

Since upgrading to Maverick my macbook pro randomly shuts down all the time, no idea why...

Since I upgraded to Maverick, my Macbook Pro shuts down quite often without warning. No idea why.

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.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks 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.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

I recently upgraded to Yosemite on MacBook Pro - unable to open iPhoto and Photo Booth

I recently upgraded to OS X Yosemite 10.10.2 on my MacBook Pro (bought in 2011). Since the Yosemite upgrade, I have been unable to open both iPhoto and Photo Booth at all. I have lots of photos and need to access them. Both icons of iPhoto and Photo Booth have a circle with a bar across them, in my dock.
When I click on iPhoto I get the message " In order to open “iPhoto”, you need to update to the latest version. The version of iPhoto installed on this Mac is not compatible with OS X Yosemite. Download the latest version for free from the Mac App Store". I have tried upgrading iPhoto on the App store but get an error message "The item you've requested is not currently available in the U.S. store" .
Since I cannot even view my photos, I cannot store them elsewhere. Please, can someone help me resolve this problem!!!
For Photo Booth, when I click on it, it says "You can’t use this version of the application “Photo Booth” with this version of OS X. You have Photo Booth 3.0.3" - gives me no option to upgrade at all.
Would appreciate help for both iPhoto and Photo Booth issues described above, with iPhoto being the most pressing concern. Thank You.

The new app is called Photos. It's icon was added to the Dock. Both, Photos and iPhoto, are located in your Applications folder.
If you need to upgrade iPhoto, follow these instructions prepared by Barney-15E: https://discussions.apple.com/docs/DOC-8431

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
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. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
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. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. 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.
6. 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. Don't log in as root.
7. 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 the browser window, 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:

☞ 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. 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 the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
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 requires administrator privileges.
11. The test may take 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 what happened. No harm will be done.
12. 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.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try 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.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. 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.

Do Not Upgrade to Yosemite w/ Macbook Pro: Severe Monitor Glitch

Jesus,
I have an early 2011 15" Macbook Pro that has been running very smooth with Mavericks OS X.
After upgrading to Yosemite my monitor has had sever issues and requires frequent restarts after the system crashes.
In hopes of a fixing this with an update, I updated to OS X Yosemite 10.10.1, but this still occurs.
This problem is especially apparent when viewing NetFlix, browsing the web with multiple tabs and using Google Maps.
The laptop's screen displays this strange glitch pattern as shown in the photo below:
When this laptop model debuted, I had this identical issue and after returning two laptops, I finally received one that worked -- at the time I believe it was running Snow Leopard.
This is a very serious issue to deal with especially while editing video. When it crashes I lose everything that I was working on.
Notes: I have enabled and disabled "Automatic Graphics Switching" in hopes of fixing this... with no luck.
I have done a SMC reset with no luck.
After resetting the PRAM, this issue still exists.
I'm looking at reverting back to Mavericks 10.9 because this glitch never occurred.
When editing, I'll plug in an AOC USB Monitor and the issue still exists.
Any ideas on a fix?

This is nothing to do with Yosemite, you have a hardware fault.
Take your Mac to an Apple Store, you're most likely going to need a new logic board.

Can't use ch340g serial port driver since upgrading to Yosemite on MacBook air

I use my MacBook air with the Arduino 1.0.6 IDE. Since upgrading ( free upgrade) to Yosemite. I can no longer acess the ch340g serial port. (does not show up in arduino ide). I tried re-installing the driver. I get no errors and am told the install was successful. This was working very nicely before the upgrade. I now have three boards I cannot use. I am at a loss as to what I should do. I suppose I could go back to Maverick but then I would have to go buy the operating system. This seems wrong to me. I was offered an upgrade that then leaves me up the creek without a paddle. Any help given would be highly appreciated.

I have the same problem, a non stable CM341 serial to tty driver on Yosemity on a MacbookPro Retina.
I followed the advice of Rsattaur, I executed the command: sudo nvram boot-args="kext-dev-mode=1" and now I have big problems with my USB-ports.
The result is a screen-of-death after connecting anything to my USB-ports!!!!

Upgrade to Yosemite on MacBook Pro with Bootcamp

I have a mid-2009 MacBook Pro 15" (2.53 GHz Intel Core 2 Duo; 8 GB memory) that now runs on Mavericks. I have a local Time Machine backup on a 1 TB Time Capsule. My machine runs Windows 7 in a Boot Camp partition. Given that description, is there anything special I need to do before I upgrade to Yosemite? I'm especially concerned about the Windows 7 partition. My instincts tell me the upgrade won't affect the Boot Camp partition, but I thought I should ask before I court disaster.

Since upgrading to Lion my MacBook Pro freezes randomly

Since I upgraded my MacBook Pro (shipped last October) to Lion, it randomly freezes.
It lasts roughly 4-5 minutes where I cannot do anything. The only running apps are Google Chrome, Skype and Twitter. All are a their latest version.
Anyone having the same issue ? Any hint ?

Try these
Reset SMC

PRAM/NVRAM
http://support.apple.com/kb/HT1379
Hardware Test
http://support.apple.com/kb/HT1509
Then backup your files to a external drive and disconnect.
Reboot holding command + r keys and enter the Recovery Partition and see if you can reinstall 10.7 over the installed version.
You might have some third party program incompatibility issue if this doesn't resolve it.
