Yosemite won't install on i-Mac running Mavericks OS

I have repeatedly attempted to install Yosemite on my i-MAC (late 2013 model) but always get the following message 'This copy of the install OS X Yosemite application can't be verified it may have been corrupted or tampered with during downloading' shortly after starting installation procedure.  I have doubled checked to make sue the day/time is set properly on the computer as this has been cited as the reason for similar message when updating OS to newer release(s).
I am going to assume this is attributable to the exceptionally long download times due to high traffic in the face of the Yosemite OS announcement.

Hello rialebR,
Thanks for using Apple Support Communities.
From your post it looks like perhaps the installer file did not download properly.  I'd like you to please delete the current installer from your launchpad, and then download the installer again from the Mac App Store.
Enter Launchpad. 
Click and hold on an icon until you see all icons jiggle.
Click the "x" button in the upper-left of the Mac App Store app icon you want to delete.
Note: If you do not see an "x" button, either the app is not from the Mac App Store or you are logged in as a standard user. 
Click "Delete" in the confirmation dialog to delete the app.

  • Can I run OS 10.6.x in Paralleles installed on a Mac running OS 10.7.2?

    Can I run OS 10.6.x in Paralleles installed on a Mac running OS 10.7.2?
    This question is related to my need to continuing using Quicken 2005, which is not supported by OS 10 7.2.  If I could load Mac OS 10.6.8 into Parallels and run Quicken 2006 in an emulated version of Mac OS, I could then run 10.7.2 and move onto iCloud.  I've looked at a couple of altehrnaftves to Quicken 2005 but none are as comprehensive as Quicken.

    Hi John,
    That is an interesting question, to which I don't know the answer. You might try it on a separate drive or partition and see how it works. I run Snow and Lion but on separate partitions on my internal HDD. If you try it please let us know how it works.

  • Mac running Mavericks Crashes Firefox Daily. EXC_BAD_ACCESS / KERN_PROTECTION_FAILURE Please help.

    Hi,
    I have a Mac running Mavericks and Firefox keeps crashing most daily for the past three months and I get a "Firefox has crashed submit report" popup.
    It is usually if I am playing a youtube video or a movie (more then one) at a time. Or if one video is loading and I try to play or load another. I notice if I "que" or pre-load a long video (more then 15 minutes), then try to play a new one it will crash.
    I have tried the following solutions none of which have worked:
    A) Uninstalling and reinstalling firefox
    B) Reset Firefox (Help, troubleshooting information, reset firefox)
    C) Turn off hardware acceleration (Firefox, preferences, un-check hardware acceleration)
    D) Turn off "enable hardware acceleration in "youtube" (it now asks me each time if I would allow it to play)
    E) Plugin Check and Updates are all up to date (http://www.mozilla.org/en-US/plugincheck/) I only have:
    SharePoint Browser Plug-in (research)
    Default Browser Helper (research)
    These plugins are up to date: (as of March 7th 2014)
    Shockwave for Director 12.0.6 (Up to Date)
    Shockwave Flash 12.0.0.70 (Up to Date)
    QuickTime Plug-in 7.7.3 (Up to Date)
    Sometimes I get this as the "signature": libsystem_platform.dylib@0x4280
    Again I have tried the above solutions but they have not worked. Any help or advice will be appreciated.
    Thank you
    Shawn

    Hi Guigs2, Thank You for the reply. Was getting worried no one was going to help me. I am not sure how to attach the crash report. I have copied and pasted it here:

  • I have a MAC running Maverick. MP3 sounds will not play in Safari or FireFox, but will play if you download the file locally to the Desktop. How to resolve this?

    I have a MAC running Maverick. MP3 sounds will not play in Safari or FireFox, but will play if you download the file locally to the Desktop. How to resolve this?

    You probably have an internet plugin installed that is preventing the MP3s from playing. I just checked a site with an MP3, and it played, rather than downloaded.
    The internet plugin folders are at:
    /Library/Internet Plug-ins and
    ~/Library/Internet Plug-ins
    (~/Library is hidden by default. Let me know if you don't know how to access it.)
    My internet plugins were all in /Library; there were none in ~/Library.
    Try moving these folders to the desktop (don't delete them), restarting, and then seeing if the MP3s play.
    They it will be trial and error to see which plugin is responsible.

  • Canon MF4890 Drivers Won't Install On Mac Running Mavericks

    I just purchased an MF4890.  I use a Macbook Pro running Mavericks.  The disk that came with the printer doesn't support Mavericks and when I download the drivers from the Canon website, they won't install.  If I keep the driver image on my Mac desktop, the printer will print for a time -- but then it no longer sees the printer.  This isn't normal.  I should be able to eject the disk image (as in every other application), and the app/drivers should be installed on my mac.  When I as much as created a folder on my desktop and moved the disk images into the folder (print/fax/scan), the mac no longer sees the printer (wireless).
    Help!  Does this printer support Mavericks?

    Hi BonnieBoop.
    The imageCLASS MF4890dw does support printing on the OS X Mavericks operating system.  You should be able to open on the Mac_MF_Ver1010_00.dmg file and run the installer package.  The icon looks like an open brown box.  Next just follow the steps to install the driver.
    If you are not able to see this information or if the setup does not allow you to save the information, we recommend that you contact us at 1-800-OK-CANON (1-800-652-2666) and a live technical support representative will be glad to assist you.
    Have a good day.

  • Problem installing Silverlight on Mac running Yosemite 10.10.2

    I've been using a streaming service successfully last year and re-signed up today.  When I tried to pick a video I was presented with a window indicating I needed to install silverlight and it provided a link.  To make a long story short I've tried
    installing silverlight (using the stream service's link which was the Microsoft download page) and using it with Firefox and Safari and get to response from the streaming site.  Checking Activity Monitor  all that appears installed is Silverlight
    preferences.  When I click on 'Microsoft Silverlight.app all it shows is a 52 bit alias. Each subsequent install I first removed EVERY file related to silverlight.  I'm stumped.  Thanks.

    Hi,
    Please make sure you are running a Silverlight-compatible operating system, browser:

  • Yosemite won't install due to a "S.M.A.R.T. drive problem that can't be repaired."

    After downloading Yosemite successfully, it won't install due to a "S.M.A.R.T. drive problem that can't be repaired."  It says to back up as much as possible and replace the drive.  Everything works flawlessly with Mavericks.  What gives??

    If you are getting a S.M.A.R.T. error then you should be more worried about losing everything on your drive then about upgrading your Mac OS.  Regardless of if you are running Mac OS, Linux, or Windows, you should never just disregard such a drive error.  S.M.A.R.T. is designed to give you a warning that your drive is statistically having far more errors than normal and should be backed up immediately and typically replaced.
    In your case, it's likely a coincidence that your drive is failing at the time you are attempting to upgrade to Yosemite.  You should stop what you are doing, backup your drive (if you don't already have the backups that you should prior to any OS upgrade), and replace the hard drive prior to moving forward.
    To make it clear, your hard drive is likely going to fail soon and you may lose everything on it at any moment.  This failure has nothing to do with Yosemite or any Mac OS.  All hard drives fail at some point.  Hopefully this S.M.A.R.T. notice has given you the opportunity to solve a major problem before it gets worse.

  • Airdrop on Macs running Mavericks, Yosemite with iOS 8 iDevices

    Found this information in discussion with Apple Advisors (and wasted a lot of time doing so) only to find a clear disconnect between KB articles.The current basic article clearly states that any Mac newer than 2012 can use AirDrop:
    In order to transfer files between a Mac and and an iPhone, iPad or iPod touch
    your iOS device needs to include a lightning connector
    your iOS device needs iOS 7 or later installed
    your Mac needs to be a 2012 or later model with OS X Yosemite installed
    Your Mac and iOS device both need bluetooth and Wi-Fi turned on. You do not have to be connected to a specific Wi-Fi network.
    Perhaps that should be (amended to) read, "... current production model Mac needs to be..." Simply saying that the MacPro line ended. Or simply delete the article in favor of the correct one? In either case though, it seems a bad idea that a computer which can run the latest OS cannot use all of the features of the latest OS, including the features that are described as being available a wide range of models of Mac machines in current production. (insert Sad Apple face here).
    More definitively this article should receive wider distribution than it has... :
    AirDrop
    AirDrop between Mac computers and iOS devices is supported by the following Mac models:
    MacBook Air (2012 or newer)
    MacBook Pro (2012 or newer)
    iMac (2012 or newer)
    Mac mini (2012 or newer)
    Mac Pro (Late 2013)
    Possible workarounds include using iCloud Drive, Photo Stream sharing.

    I got my answer:
    "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. To transfer files between two Mac computers, you need one of the Mac models listed below and OS X Lion or later."

  • Docs to go won't install on my mac

    Hi,
    I've recently bought a palm TX, and have been experiencing trouble  with the included software apps for my mac.
    I've installed palm desktop, and some of the other apps such as adobe reader, but for some reason docs to go won't install.
    i can load the disk image off the CD, click on the VISE installer icon, accept the terms of use, but it get's stuck when the progress bar appears.  the last thing it says before "not responding" is...
    items to install 240
    "searching  [computer name]"
    or something along those lines
    I've tried repairing disk permissions, i'm logged in on the admin account, reinstalled palm desktop and there are no other apps running.
    I'm using OSX 10.4.11 (tiger), a palm TX, and the palm desktop version is 4.2.2
    I've also tried downloading 4.2.1 rev D but same result.
    please help!
    Post relates to: Palm TX

    Thanks for your reply,
    The version included on the CD is Docs to go ver 7.  According to the datavis website, it's mac compatible, and it certainly looks like a mac compatible installation procedure.
     I've found getting technical help from datavis pretty much impossible, as i need a registration no. to e-mail for support, and as I can't even install the program, I've got no registration no.
    Is there anyone else out there with a TX using docs to go on their mac???

  • Yosemite won't install. Tells me to repair my hard drive, but repair disk button is greyed out!

    Ive been trying to install Yosemite for hours. It gets to the installation phase, where it says it will take 22 minutes. Nothing happens until finally there is a message that says: file system verify or repair failed and to quit the installer to restart. I've tried that a few times, but I get to the same point. I also tried to go to utilities where I tried to repair disk, but it's not available so I'm told to do verify disk first and from there I'm told to repair disk, but the button is greyed out and I have no more options and a computer that is stuck in limbo!

    Disconnect all peripherals from your computer. Boot from your install disc (Tiger?) & run _*Repair Disk*_ from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
    Select your language.
    Once on the desktop, select Utility in the menu bar.
    Select *Disk Utility.*
    Select the disk or volume in the list of disks and volumes, and then click *First Aid.*
    Click _*Repair Disk.*_
    Restart your computer when done.
    Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.

  • Mavericks won't install on newest mac mini fusion drive

    I have a mac mini, latest version.  I have a fusion drive.
    Mavericks won't install on that drive.  I get this message:
    This disk doesn't use the GUID Partition Table scheme. Use Disk Utility to change the partition scheme. Select the Disk, choose the
    partition tab, select the volume Scheme and then click Options.
    Well, I did that, up to "choose the partition tab."  Then it says "you may only split this partition into two. To do this, click +."
    I did that, and there were two partitions.  the only option left is to select apply, which I didn't.
    The "options" were still greyed out.
    So now what?
    Thanks for any input.

    Lion creates a recovery area with a minimal version of OS X and it may be unable to do so due to use over the years, and possibly other resizing operations (Boot Camp).  It could just need more space, if you only have less than 8gb free.  Lion shuffles and merges the two systems when it upgrades.  You can burn the image downloaded from App Store by finding the dmg file inside the "Install Mac OS X Lion.app" bundle, dragging it into disk utility, then burning from there.
    Otherwise, you can appropriate a MBR/BIOS formatted 4GB thumbdrive, 8GB of either EFI or MBR/BIOS thumbdrive, flash storage device, or external hard drive, and format it, using the restore operation through disk utility to copy the contents of the installer disk to the media.  Exposed via the alt key before the Apple logo, should show the bootable media, where you can format over the former installation.
    As always, backup your files when upgrading.  I recommend if your installion is over a year old to wipe and upgrade if you can't make otherwise the media bootable, using your 10.6 recovery dvd.
    If you cannot find an external medium to backup your files before the upgrade, if you need to format via disk utility (Through 10.6 media), you can consider Dropbox as an option (2GB free account).
    It's not uncommon for the partition to simply refuse operations, including upgrades and resizing.
