Hello liel ben simon:
Could it be due to your internet connection? Can you get to any web sites on Safari or your favorite browser? I have a feeling it is something simple.

Very strange. I am aware apple might have had isues with their server yesterday as a friend fo mien was only getting about 128 kilibits down from their store. Keep trying.

I also have an audio and vidual guide in the yosemite bundle I have at [this link](] where I have the tex file included witht he bundle, the reason beeing I could not go over all 3 methods due to time and space.

Hope that helps.

What message are you getting in regard to itunes? It's not very clear.

Also to the person who got the 404 I think I might have mistyped. Thanks fingers. Lol!

I know someone had trouble yesterday with some other of our services but all seem to be working today..

Try this and see what you get.

For the person using itunes you don't need it when doing a clean install, just download the app file and make a clean boot disk. I'll actually paste a portion of the text file in another message.

Option 1: Use createinstallmedia

Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (The Terminal command used here assumes the drive is named Untitled.) Also, make sure the Yosemite installer, called Install OS X, is in its default location in your main Applications folder (/Applications). This means that if you moved it before installing Yosemite, you need to move it back before making your installer disk.

  1. Select the text of this Terminal command and copy it: sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction

  2. Launch Terminal (in /Applications/Utilities). Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.

  3. Type your admin-level account password when prompted, and then press Return.

  4. The Terminal window displays the progress of the process, in a very Terminal sort of way, by displaying a textual representation of a progress bar: Erasing Disk: 0%... 10 percent...20 percent... and so on. The program then tells you it’s copying the installer files, making the disk bootable, and copying boot files. Wait until you see the text Copy Complete. Done. (

You now have a bootable Yosemite install drive. If you like, you can rename the drive from its default name of Install OS X Yosemite, though I think it’s kind of a catchy name.

Has anyone had any joy with a clean install improving bumps in the OS?

I can't believe there have been no comments or responses to this in three months. I may have to make one of these myself to try it. Better back up my machine first though, eh?
