I can not update my mac to 10.9


Hard to say without knowing exactly what Mac you have and what specs, but most likely reason would be your system doesn't meet the requirements (From Apple support site) - To install Mavericks, you need one of these Macs:
  • iMac (Mid-2007 or later)
  • MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
  • MacBook Pro (13-inch, Mid-2009 or later),
  • MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
  • MacBook Air (Late 2008 or later)
  • Mac mini (Early 2009 or later)
  • Mac Pro (Early 2008 or later)
  • Xserve (Early 2009)
Your Mac also needs:
  • OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
  • 2 GB or more of memory
  • 8 GB or more of available space

I am running OS X 10.4.11 and would like to upgrade my operating system?


Please provide more information.
To what would you like to upgrade it?

Since OSX Mavericks was just announced, I'm going to assume that's what you're wanting to upgrade to.

Not all Macs can run Mavericks.

Mavericks Capable Macs

Mavericks, like its predecessor Mountain Lion, requires one of the following Macs with at least 2 GB of RAM and 8 GB of available hard drive space:
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Air (Late 2008 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)

If your Mac isn't one of the ones listed above, you won't be able to upgrade.

If you have an iMac, MacBook, MacBook Pro, or Mac mini model that was originally released in Early/Mid 2006, the latest version of Mac OS X your system supports is Snow Leopard.

I removed the back up drive from my iMac with out reading directions; just unplugged it! Now I replaced the line into the USB and it is not working and not shoiwng up on the computer. What do I...


Before you unplug an external hard drive, you need to unmount it first. If you don't, you can cause all kinds of problems.The term "unmount" basically means to prepare a drive to be unplugged from the Mac. In addition to external hard drives, "thumb drives" a/k/a "jump drives" as well as some cameras need to be unmounted before they are unplugged.When you unmount a drive, Mac OS X checks to see if you have any open files that are stored on that drive. If you do, the drive cannot be unmounted. This is a safety feature because if drive is removed with open files on it, the application that is using those files can become confused and you can lose or corrupt your data.
If you unplug a hard drive that has not been unmounted, Mac OS X will pop up a box with a red Stop icon and a message that you shouldn't have done that. Nice info, but a little late at that point.
I'm not saying that you will lose data every time you unplug a mounted drive, but the danger is there. I recently worked with someone who had his iPhoto Library on an external drive and he never unmounted the drive before unplugging it. It wasn't a problem for a long time but one time he opened iPhoto and all of the photos were missing.
Unmounting a drive is easy. There is an Eject icon to the right of the drive name in the DEVICES section of a Finder window. Just click that icon.
If you have multiple partitions to unmount, you can hold down the Option key when you click the Eject icon to unmount them all at once.
I thought about it and did some looking and I couldn't find anywhere in Mac OS X that states the need to unmount before unplugging, other than the big Stop icon you get after the fact. I don't think it is something you are likely to think of on your own, either. But now you know.

I would suspect that either the USB cable or port is the problem. Change the USB port (On the Mac or on the WD MyBook (I don't know if it has more than one USB port) that the cable is connected to and see if that improves the situation, if it still happens change the USB cable. Hope this helps.
