Since downloading Yosemite, I have had performance, battery, and overheating issues. Help?

Hello,
I've been quite unfortunate with my laptop (Macbook Pro Early 2011) ever since downloading the Yosemite OS. It has been plagued with extremely slow speeds when running basically anything, the fan runs constantly, and the battery drains at a rate of 1% every minute it seems. I can typically only get an hour or 2 out of my MBP without having to run and find an outlet.
The performance is extremely slow when opening apps, but not so bad once they are open and running. However, switching apps (e.g. from Chrome to iTunes) causes a long lag and leaves me unproductive. Some apps don't even open. It takes about 5 minutes to open one app, and about 15 minutes on average to use my computer once again after restarting.
I've looked at various other discussions where people had problems, but each situation seemed unique with no solution working for everyone. I used Etrecheck to analyze my computer, but not knowing a lot about computers, I didn't find a solution. Below you will find the data. Any insight or solutions would help so much! I hate always having to be plugged in and burning my legs when my laptop is on my lap.
EtreCheck version: 2.0.11 (98)

Since downloading Rosemite I have had long delays in starting up my iMac ?

I downloaded Yosemite on my iMac on 20.10.14 and have been experiencing long delays in starting up each day ?

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ 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 Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the BOOT_TIME log message that corresponds to the last boot time when you had the problem. Now clear the search box to reveal all messages. Select the ones logged after the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes   after the boot time, not before. Please include the BOOT_TIME message at the beginning of the log extract—not at the end.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A GPU restart report has a name that begins with "Kernel" and ends in ".gpuRestart". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Since installing Yosemite I have had difficulty in starting my iMac. Either its a blank screen or I get the rainbow wheel.

Two days ago I installed Yosemite. On start up I now get either a blank screen and have to power down by holding the start button or I get the rainbow wheel which takes ages to clear.

I notice that the home page redirects to a secure (HTTPS) address. I wonder whether there is a setting blocking this? What if you go directly to a secure page -- will it load?
https://www.itvsn.com.au/include/sweb.dll/product?product=155602&category=92010&site_id=ITVSN
Your add-ons list shows AVG, ZoneAlarm, and McAfee products. Could one of them be blocking this site? See whether you can add exceptions or just disable them temporarily and test whether that helps.

After downloading Yosemite I have lost my contacts

after downloading Yosemite I have lost my contacts and the folder they were in on my dock. How can I recover them?

Patty1277,
Look no further help is here! I can definitely understand your concern. Keeping your contacts safes is definitely important.
Were the contacts deleted from the phone as well? How were they deleted? Did you have backup assistant or the Verizon Cloud on the phone? Were you backing up the contacts using your Gmail account?

Since downloading Yosemite 10.10.2, emails are not automatically downloaded.I have to either click on Get Mail or click in and out of mail inbox.

Since downloading Yosemite 10.10.2, emails are not automatically downloading. I have to either click on Get Mail or click in and out om mailbox.
It's very frustrating as it does not happen on my iPad or Iphone.

Howdy welcon,
It sounds like your Mail application is not checking for mail automatically anymore after updating to 10.10.2. It seems to me that the setting for this may have reset, or changed at some point thereafter so I would check the preferences for the Mail application:
General preferences - Mail Help
Check for new messages
When Mail gets new messages from the mail server. By default, the option is set to Automatically (Mail varies how often it gets messages, based on whether your Mac is plugged into an electrical outlet).
An IMAP account may get messages more frequently if the mail server supports the IDLE command; make sure the option to use it is selected in the account’s Advanced pane in Mail preferences.
If you set the option to Manually, click the Get Mail button in the Mail toolbar to check for messages. (Whenever you click an IMAP or Exchange mailbox, it syncs with the server, and shows new messages.)
Thank you for using Apple Support Communities.
All the very best,
Sterling

Since downloading Yosemite Flash Player not working. Have downloaded Flash Player for Mac, but still not working. Is there a fix for this? Thanks.

Since downloading Yosemite Flash Player not working. Have downloaded Flash Player for Mac, but still not working. Is there a fix for this? Thanks.

1. System Preferences > Flash Player > Advanced > Delete All
     Press the "Delete All" button.
     Install Adobe Flash Player.
    http://get.adobe.com/flashplayer/
   Download it first.
   The next step is important.
   Click Safari in the menubar and select “Quit Safari”.
   If it doesn’t quit, Force Quit it.
   Press command + option + esc keys together at the same time. Wait.
   When Force Quit window appears, select the application if not already.
   Press Force Quit button at the bottom of the window. Wait.
   Application will quit.
    Follow the prompts and install it.
    Restart computer. Relaunch Safari.
2. Allow Plug-ins
    Safari > Preferences > Security
    Internet Plug-ins > "Allow plug-ins"
    Enable it.

Since downloading Yosemite, Safari will close itself out at times and I loose all the pages I had open. How can I stop this from happening?

Since downloading Yosemite, Safari will close itself out, when I reopen it all of my pages are gone. How do I stop this from happening?

But if iit won't stay open, then it's quitting unexpectedly which is the same as a crash.
There has to be a reason for that which a crash report should reveal.
Check ~/Library > Logs > Diagnostic Reports

Ever since downloading Yosemite I see constant coloured beachball

Ever since downloading Yosemite, my Macbook Pro shows the coloured beachball all the time. Why?

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:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ 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.

I am unable to scan on my Epson Artisan 730 since downloading yosemite

Since downloading Yosemite on my Mac Book Pro I am unable to scan on my Epson Artisan 730 printer. The printing function still works.

Did you add the printer using the AirPrint driver? If so, add it again using the Epson driver (by selecting the Epson driver in the "Use" menu in AddPrinter). If you don't have the Epson drivers installed, you can download them here:

Hope this helps.

Why won't iPhoto update since downloading Yosemite?

Hi,
I downloaded Yosemite recently (maybe a week ago), and when I tried to open iPhoto from the apps folder, the icon had a circle with a slash through it. I clicked on it, the message popped up that I needed to update. This then took me to the Apps store, where I saw that all my iWorks apps needed updating. Once I clicked Update all, I received the message...
I don't understand what that means. All of the apps were on the my Macbook when I bought it and they've had no issues updating up until now. The last version of my iPhoto is 9.2.3, if that means anything.
Thanks for all help.

With Yosemite you need to update to iPhoto 9.6.
The error message means, that iPhoto is not associated with your AppleID and so you cannot update it. Check, if iPhoto is showing on the "Purchased" tab of the AppStore. If there is an "Accept" button, press it.
Accepting associates your Apple ID with the preinstalled iPhoto. It should move iPhoto from the "Accept" portion of the App Store to the "Purchased" tab. After that, you should be able to update iPhoto from the Updates tab of the AppStore.
If you do you not see the update there, try to buy iPhoto. iPhoto may show for free, so you do not have to pay again.
Backup your iPhoto library, if you do not have a current backup.
Uninstall iPhoto by deleting it from the Applications folder, otherwise you cannot buy it again. But do not empty the Trash, so you can put iPhoto back, if need be.
Launch the App Store, click the "Store" menu, and sign in with your current AppleID.
Open the main page "Featured" of the App Store and search for iPhoto.
If iPhoto is listed as "Free", click the "Free" button to buy it with your current AppleID.
If it is not showing as free, there is no help but contacting the App Store Support to sort out the AppleID. Use this link: http://www.apple.com/support/mac/app-store/contact/
After you update iPhoto, your iPhoto Library will need upgrading. Make a backup of your iPhoto Library, before you open iPhoto the first time after updating.

Since downloading Yosemite Safari will not open or takes forever to open 3-5 minutes. Help would be greatly appreciated

I have a problem with Yosemite working with Safari, Chrome, and Firefox, although I use Safari more than the other two it is the worst with this problem.
They all take forever to open since downloading Yosemiite. Safari does not open at all sometimes. help would be appreciated

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall OS X: Select Reinstall OS X 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.

Iphoto will not update since downloading Yosemite

iPhoto will not update since downloading Yosemite--any help?

Cancel the updates. Delete the apps. Redownload them from the Purchases tab in the App Store.

Since installing Yosemite, I have no sound.

Since Installing Yosemite, I have No sound. There is no sound if I use headphones either.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Since downloading Maverick I have a long hang time, computer crashes, can't use word and I can't access finder, why?

Since downloading Maverick I have a long hang time, computer crashes, can't use word and I can't access finder, why? Also, iTunes is horrible. While I'm listening to my music iTunes will just stop playing the song for at least 5 minutes and I can't force quit why does it do that? This is the first time I have ever felt like my iMac is just as bad as a PC and I wonder if Steve Jobs would have let the program be relase to the public with all the problems involved. No wonder Maverick was free. IT ***** BIG TIME!

Hello, vanvu.
Thank you for visiting Apple Support Communities.
Since you are experiencing this issue with both a wired and wireless connection only on your home network and not at other locations, this issue would related to your router. I would first recommend power cycling the router and testing the connection again. If the issue persists, try updating your routers settings per the article below.
