Windows- bootcamp won't start after installing OSX Yosemite - Ameriguayo

Like so many others, I installed OSX Yosemite this morning and now Boot Camp no longer works.
After I updated to Yosemite I restarted my computer, held down alt, and was presented nothing but a Macintosh HD. I followed “Loner T’s” instructions. Here's my info...

Your case may be simpler to resolve. You do not have the MBR entry for Windows.
Do you a NTFS header "R.NTFS" when you run the following command in Terminal?
sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

Can't Install OSX Yosemite on iMac Mid-2009 Stuck - No Recovery Partition PLEASE HELP

I had an old iMac Mid-2009 2GB on OSX Lion, which had been kept away in the garage for a while. Pulled it out, ran Lion fine. It was going to be set up as a new computer, so I downloaded OSX Yosemite, planning to wipe and re-install after installation. Took a lot longer than I expected. After a while, the apple logo progress bar froze. I googled it and many people said just to wait it out, it could take up to 12 hours. 1 week later, still there. Fairly confident that nothing was going on on the hard drive. I reset the PRAM, didn't help. So I tried another fix I found which involved booting into the recovery partition. Guess what, no recovery partition . So finally I went to the trouble of creating an install usb. Booted fine, so I went into Disk Utility to erase my hard drive and re-install. But guess what, I couldn't! Can somebody please help! Or is this iMac stuffed?

Finally figured out the solution. My internal HDD appears to be not working after that faulty Yosemite installation. Just got a fast external HDD, plugged it into the iMac. Booted from the USB, went into Disk Utility and formatted it as Mac OS Extended (Journaled) in GUID. Installed and got up an running fine. Finally fixed this after 3 weeks! Hopefully this will help anyone that has the same problem.

My safari won't open since I installed OSX Yosemite

My Safari hasn't opened and functioned properly since I installed OS X Yosemite 10.10.1 on my Mac Book Pro. Processor 2.66 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3. Is it possible to reinstall Safari?

There is no need to download anything to solve this problem.
You may have installed the "Genieo" or "InstallMac" ad-injection malware. Follow the instructions on this Apple Support page to remove it.
Back up all data before making any changes.
Besides the files listed in the linked support article, you may also need to remove this file in the same way:
~/Library/LaunchAgents/com.genieo.completer.ltvbit.plist
If there are other items with a name that includes "Genieo" or "genieo" alongside any of those you find, remove them as well.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, then you may have one of the other kinds of adware covered by the support article. Follow the rest of the instructions in the article.
Make sure you don't repeat the mistake that led you to install the malware. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates
if it's not already checked.

Can't re install OSX Yosemite

Hi,
I have multiple problems on a 13" macbook Pro. (late 2009) which has no backup..
1. Computer shuts down after about 1 third of booting.
2. Unable to boot in safe mode.
3. Unable to re install Yosemite because disk is locked.
Would anyone have any idea on how to unlock the disk so I could re-install Yosemite without having to wipe the disk first ?
Thank you for your help guys !

Disk can be locked for many reasons. In your case, the most possible case is that you have a software (or Hardware) corruption on your Hard Drive. Boot your Macbook Pro to Recovery mode: OS X: About OS X Recovery - Apple Support
From OS X Utility Window select Disk Utility, and when this tool is fully loaded, select your OS partition (by default called Macintosh HD) and Verify Disk first and if necessary Repair Disk if possible:
Using Disk Utility to verify or repair disks - Apple Support
Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
If Disk Utility cannot repair your disk, then you will need to Erase your drive and reinstall OS X (this will also wipe all of your data): OS X Yosemite: Erase and reinstall OS X
If you do not have a backup of your files then you have a few options that you could try to attempt to rescue your data but this will require additional devices and your patience...
You could try Target Disk Modet: OS X Mountain Lion: Transfer files between two computers using target disk mode
If you don't have an access to other Mac, but you do have an access to empty USB External Hard Drive, then by booting your Mac to Recovery Mode, you can install OS X on External Hard Drive (use external Hard Drive partition as a destination disk for OS X) and that will give you an option to access files on corrupted drive to copy them before erasing your Internal Drive and Installing OS X again.

I have a licensing Problem reinstaling Acrobat 9 now under new installed OSX Yosemite.

Troubleshooting incl. deleting directories etc. doesn't help. Any idea?
The repair tool doesn't seem to work (Adobe - Adobe Licensing Repair Tool), the launcher comes up with the error message, it's not longer supporting Power PC
I have a late 2011 MB Pro with a new Install of OX Yosemite

Here is the compatibility statement for Acrobat Pro on a MAC:
Adobe Acrobat 9 Pro (English, French, German) on Mac OS
PowerPC G4, G5, or Intel processors
Mac OS X v. 10.4.11 or 10.5
256 MB of RAM (512 MB recommended)
1.42 GB of available hard-disk space
1,024 x 768 screen resolution
DVD drive
I am not sure how to interpret the OS for a MAC, but it is what is stated. I don't think that Adobe certifies AA 9 for Yosemite, but that does not mean it will not work.

Installing OSX Yosemite is taking too long

I am upgrading my operating system from Maverick to Yosemite. The download took a long time and now the installation is taking longer. It's been stuck on "About a minute remaining" for 2 hours now. how long should it take? How can i abort the installation?

If you have files in /usr/local, then these files are copied over one at a time into the new /usr directory. This process can take many hours. See https://news.ycombinator.com/item?id=8467350 for details. Here is what I did:
Use cmd-q to abort the install.
Reboot into recovery mode (hold cmd-r until apple startup is seen)
Open terminal window (it is one of the menu selections)
Move /usr/local into your home directory. Something like: mv /Volumes/MacOSX/usr/local /Volumes/MacOSX/Users/myhome/
Reboot. It will automatically redo the upgrade.
After the upgrade, move /usr/local back with something like: ditto -V ~/local /usr/local

Windows- bootcamp won't start after installing OSX Yosemite

Hi Loner T,
Like many people with the yosemite update, my boot camp no longer works.
I cannot find the drive when I'm booting up.
Startup Disk under system preferences only shows the Mac system and does not show any other option.
I've been trying to go through what you've posted to help other people but I've never even worked with terminal application before and everything is very confusing.

Hope you can help me, Thank You.

The NTFS header is intact and the GPT and MBR match.
1. What happens if you power cycle and hold the Alt key?
2. Do you have any third-party NTFS software (Tuxera, Paragon, MacDrive, NTFS-3g, NTFSFree...)?

Since upgrading to OSX Yosemite cannot open word files downloaded from email.

I have recently installed OSX Yosemite on my late 2010 macbook air. Since upgrading I have been unable to open files in Word that I have downloaded from my email. Old word files seem to work fine. My university has given faculty access to "Office 365" and that is what I use for my email. However whenever I try and download a word file from my email the computer opens word for a second - I can see the first page of the document - and then immediately closes. This happens regardless of whether or not I open the file from my computer in my desktop or in my downloads folder, or just download another copy from my email. The word file works fine on another windows computer, it's only on this mac that Office 2011 crashes every time I try and open this new file. Please advise?

A web site for the community I live in. I can get into the site but when I try to open a PDF file all I get is a grey screen. I can open PDF files from mail, and other sites.

Please test after taking each of the following steps. Back up all data before you begin.
Step 1
Quit the Contacts or Address Book application if it's running.
Triple-click anywhere in the line of text below on this page to select it:
~/Library/Caches/com.apple.AddressBookSourceSync
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.
Repeat with this line:
~/Library/Containers/com.apple.AddressBook
*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 (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
If you use iCloud, uncheck the box marked Contacts in the iCloud preference pane. Press return to confirm, or click Keep on Mac in the dialog that opens.
If you synchronize contacts with any other network service, disable that synchronization in the Internet Accounts preference pane.
Step 3
From the list of groups on the left side of the Contacts window, select All On My Mac. If that group doesn't exist or is empty, skip this step. Otherwise, from the menu bar, select
          File ▹ Export... ▹ Contacts Archive...
Save the exported archive to the Desktop.
Step 4
Quit Contacts. Reveal the following item in the Finder as you did in Step 1:
~/Library/Application Support/AddressBook
If you know when the problem started, and you can restore that folder from an earlier backup without losing any contacts, do so and test. Otherwise, move the folder to the Desktop, leaving the window open for now.
Step 5
Launch Contacts. Your contacts and groups will be gone. If you took Step 3, then double-click the file you created in that step and confirm that you want to import from it. Your contacts and groups will reappear.
Step 6
If you took Step 2, reverse it. Test. If the issue is resolved, delete the AddressBook folder and the archive file on the Desktop and close the open folder window.
Otherwise, quit Contacts again and put the AddressBook folder back where it was, overwriting the newer one that will have been created in its place.
Step 7
Go back to Step 3, but this time choose Export vCard... from the Export menu. Continue as in Steps 4-6. All contacts should be preserved, but you may lose some metadata such as group membership.

Airdrop on osx yosemite

I have an iPad air and iPhone 5s. I also have a macbook pro 13 early 2011. Now with the previous OSX and IOS versions airdrop just works with both IOS devices. I found out that you can airdrop a file to a mac as long as you have IOS8 and OSX mavericks installed on your iOS device and computer. I installed OSX Yosemite earlier today. I tried airdropping a photo on my mac. They won't see each other. Bluetooth is enabled on my mac and iPad. I also tried using my iPhone it's still the same thing. Is there a way to fix this problem?

Hi misterclutch,
Thank you for using Apple Support Communities.
To AirDrop files between an iOS device and a Mac running Yosemite, the Mac needs to be a 2012 model or newer.
In order to transfer files between a Mac and and an iPhone, iPad or iPod touch, your iOS device needs iOS 7 or later installed and your Mac needs to be a 2012 or later model.
Mac Basics: AirDrop lets you send files from your Mac to nearby Macs and iOS devices
Take care,
Alex H.

OSX Yosemite breaks Bootcamp

I would like to install osx Yosemite on my Macbook retina 15", but some people say it breaks the Bootcamp. Unfortunately i sometimes need to use Windows (8) for work (to use 3D softwares that doesn't accept mac) and my bootcamp. Can i install Yosemite without risking to lose my bootcamp or windows partition?? thanks

Hi Loner,
Unfortunately, should have read this before upgrading the yosemite while having the bootcamp.
I have noticed you have successfully advised some users on recovering the windows files and data.
I have followed your notes:

Does that mean that all is lost??
Could you please elucidate me whether it is possible to recover the data I had in the bootcamp partition and what should be the next steps?
Many thanks,

Bluetooth problem with OSX Yosemite: Magic Mouse and Keyboard

Hello everyone,
I've a problem on my MacBook Pro with Retina Display 13" (late 2013).
I've always used it plugged with an external monitor (I love double screen), magic mouse and bluetooth keyboard. On Mavericks everything was perfect with this setup.
Yesterday I installed OSX Yosemite and I've found a boring problem: my Magic Mouse and my Bluetooth Keyboard have a 0.5 second of latency, lag. This happen when the Macbook is not plugged with battery charger. When he is on charge, the problem don't exist.
I noticed this bug also on the public beta of this summer and submit the feedback.
I hoped that they fixed this before release but the bug is still here.
How can i solve this boring problem?

I also reported this issue again and again during each beta release.
This makes the MacBook basically unusable in battery power for doing any kind of design and coding work.
I don't have any bluetooth addons or third party utilities. I also tried clearing PRAMs, and reinstalling Yosemite, to no avail.
Here are some threads about the issue, which, I'm noticing, is common.
http://forums.macrumors.com/showthread.php?t=1802931
http://forums.macrumors.com/showthread.php?t=1802838
Note that while the issue is kind of tolerable using the mouse, it's tragic with the keyboard.
Does this prevent you from using OS X Yosemite?
The issue makes it very difficult for me to use OS X Yosemite
For the report, here are the issues I submitted about this using the feedback assistant:
#116709, #128648, #129129

Boot Camp won't start after OSX Yosemite upgrade

Like so many others, I installed OSX Yosemite this morning and now Boot Camp no longer works.
After I updated to Yosemite I restarted my computer, held down alt, and was presented nothing but a Macintosh HD. I followed “Loner T’s” instructions…

I’m in serious trouble if I cannot repair this issue. PLEASE HELP.

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.
The Etrecheck report clearly shows that SylvieRose has a Macbook Pro, not a Macbook Air and that there are only 2 GB RAM installed. The Etrecheck report can be very informative if one takes the time to examine it.
Ciao.
