Wifi keeps dropping out on MacBook Pro after installing Yosemite

Wifi keeps dropping out on MacBook Pro after installing Yosemite. This is not good. Apparently, a lot of people are having this issue with Yosemite. Any suggestions for my MacBook Pro? It's bad enough that Yosemite looks so boring, but to have a major issue like constantly disconnecting from wifi is deplorable.
I plan to keep Mavericks on my iMac until this issue is resolved.

Can't boot macbook pro after installing yosemite

I installed Yosemite last night. Installation went smoothly, but when the mac reset and try to boot the loading bar on the black screen with the apple symbol, didn't move for hours.
I have been keeping up to date with the other post on here and have tried
- Reseting the PRAM
- Booting in recovery mode and turning off the wifi
- Reinstalling Yosemite from recovery mode
- Booting in safe mode and removing all of my login items
Currently every time I reset, the loading bar on the black apple logo screen stops in one of three spaces.
Does anyone have any other ideas? I have my files backed up so if it comes to it I can reset the mac, but I hope it won't come to that.

You might try to reboot and hold the option key down to see if the screen illuminates. If it does then you can choose from an external disk or your main drive.
OR
About Lion Recovery
Recovery System
OS X Lion or OS X Mountain Lion includes a built in set of utilities in the Recovery System. Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears, indicating that your Mac is starting up. After the Recovery System is finished starting up, you should see a desktop with a OS X menu bar and a "Mac OS X Utilities" application window. Note: If you see a login window or your own desktop and icons, it is possible that you didn't hold Command-R early enough. Restart and try again.
In order to reinstall OS X Lion or OS X Mountain Lion, you will need to be connected to an Ethernet or Wi-Fi network. The Wi-Fi menu item is in the upper-right corner of the screen. Click the icon to display all available Wi-Fi networks. Click your preferred network name and, if needed, enter a username and/or password.

Hey KeyofNorth,
Thanks for the question. The following resource outlines troubleshooting steps if you are seeing a gray screen with a prohibitory symbol:

Macbook pro not booting after installing yosemite

I have just installed Yosemite and it now won't boot up. I just have a circle with a line through it on my screen. No idea how to resolve this! Any suggestions please.

Hi veerta,
If you're having issue with booting, the following article covers most of the general boot issue troubleshooting:
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
http://support.apple.com/kb/ts1417
You may also want to see if OS X is showing as a bootable volume in Startup Manager, as outlined in this article:

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!

Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
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.

My MacBook Pro (Retina, Mid 2012) is too slow after installing Yosemite version 10.10.1. All programs take for ever to load especially Safari and even chrome. I regret upgrading to yosemite, it was all fine with Maverick. Any suggestions ? ThankYou

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.

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.

Macbook Air Late 2010 display flickers after installing Yosemite

Hi !
I'm from Germany.
i have upgraded my Macbook Air, Late 2010 from Mountain Lion to Yosemite last Saturday.
The Installation works fine. At the first Time i have no problems, but:
One Day later i start my Macbook Air normally. Now the left side of the screen is flickering.
There are vertical lines to see. The right side of the integrated screen is ok.
i have resetted the SMC and the Power Management.
Please help, what can i do ?
Greetings
iRoGo

I noticed a similar issue with my MBA 2012 after installing Yosemite. The screen flickers slightly most of the time now. It's more noticeable with dark backgrounds. It almost 'vibrates' and is very annoying. Reminds me of an old monitor with a low refresh rate. I reset the SMC, PRAM, etc. and contacted Apple, who had me go through the same steps. The flickering is still present when booted into Recovery Mode. When I boot into Safe Mode the issue gets dramatically worse and I see screen artifacts like iRoGo describes -- parts of the screen blanking out, whole screen/parts of the screen flickering on and off, lines appearing, etc. It's basically unusable in Safe Mode.
At this point the issue seems to be hardware-related (i.e. issue persists in even in Recovery Mode), but I'm suspicious seeing that it manifested right after installing Yosemite. I will be bringing my MBA to Apple for service later this week...

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I just installed MacOS X Yosemite on my MacBook Air 2011. After installing Yosemite I installed the Photoshop Elements 12.1 upgrade, but now when I open the program and try to use the tools, the program freezes. How do I fix this problem?

If you use a trackpad and don't want to switch to a mouse, you can uninstall and reinstall all day long and will still have problems, but if you really want to try it, you can download PSE 12 here:

Pictures disappeared after installing Yosemite and new Iphoto. Why

Pictures disappeared after installing Yosemite and new Iphoto. Why ?

I also started having problems with iPhoto after installing Yosemite. Some of the Event collections lost the picture and just has a grey square in its place. When I click on the Event, it shows a white dotted lined square for each picture and if I click on the picture, it shows an exclamation mark.
Check, if you also are having a folder "Old Masters" inside the iPhoto Library package, as described by Muhamad Abdulkadir.
Ctrl-click (or right-click) your iPhoto Library in the Pictures folder , then select "Show Package Contents". If you are seeing a folder "Old Masters", copy this folder out of the library. Look inside - are the original image files of the problematic photos inside?
Are any photos in your "Masters"folder?

MacBook Pro Retina Late 2013 UI Lag after installing Yosemite

Hey everyone,
Ok so my Issue here, and I think I'm not the only one but my MacBook pro retina late 2013 (8GB ram, 256gb SSD) has been experiencing numerous issues after installing Yosemite. For example, the UI lag is at times horrible; after opening several apps, and especially after having a pdf or two open in preview everything becomes so sluggish. the animation of switching to mission control is painstakingly slow, and opening new tabs in safari takes 2 or 3 seconds. I've done a clean install of yosemite but nothing seems to help, what should I do; just revert back to mavericks and cross my finger for a future update?
Any help would be much appreciated, thanks so much !

i am in the same situation as you, late 2013 retina MacBook Pro 15 inch upgraded to yosemite and then clean installed yosemite b/c of UI lag after opening several apps at once... I found that yosemite drained my battery life too, on mavericks i was getting 5-8 hrs of battery life, on yosemite i was getting like 2-3 hrs most.
After exhausting every option out there (apple store genius bar help, apple repair, etc), I came to the consensus that my macbook had no hardware problems at all, it's basically a software problem on apple's end. and until they update yosemite with a specific fix for the UI lag and the battery consumption problems, i am not going back to yosmemite.
what i did was clean installed back to mavericks... this solved every one of my problems, NO LAG, NO BATTERY ISSUES, back to buttery smooth performance, of course without the new UI however... but i can live without new design
this experience tells me several things: 1. the new apple under the leadership of cook is slowly but surely sacrificing quality of software for unnecessary updates(sales) 2. mac hardware is still good but who knows for how much longer

Why wont my macbook boot after installing yosemite 10.10.3 ?
