Does anyone know how large the USB drive has to be for a clean install? I always used 8GB so far, but somewhere I read it's 16GB for El Capitan...
I don't remember how big it was, but el cap beta fit easily on my 8gb stick

how to make USB drive to clean install? i think it uses Terminal last time i did it but i don't remember.

Thanks

I stole this from Macworld:

Option 1: Use createinstallmedia
Starting with Mavericks, hidden inside the OS X installer is a Unix program called createinstallmedia, provided by Apple specifically for creating a bootable installer drive. If you’re comfortable using Terminal, createinstallmedia is a relatively simple tool to use.

As mentioned above, the createinstallmedia tool works only in Lion, Mountain Lion, Mavericks, or Yosemite—you can’t create an installer drive this way while booted into Snow Leopard. If you need to create a Yosemite beta install drive while booted into Snow Leopard, you should use the Disk Utility instructions, below.

Using the createinstallmedia command in Terminal
Here are the required steps:
  1. 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 Yosemite.app, 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.
  2. Select the text of this Terminal command and copy it:
    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction
  3. Launch Terminal (in /Applications/Utilities).
  4. 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.
  5. Type your admin-level account password when prompted, and then press Return.
  6. 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. (see the screenshot above), which could take as long as 20 or 30 minutes, depending on how fast your Mac can copy data to your destination drive.
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.

Hi Aneef wow that 3g/4g deal is good thats less than half what I pay for twice the amount of data in the UK. Reasonable speeds too. I findp the Huawei B315 (UK) the best but different countries have different model numbers I get 1800 spectrum on 4g EE UK this modem made a _big difference_ to speed.
I'm using Huawei E8372 wingle for my Mobile broadband and it is pretty good too. Here too the spectrum is 1800 MHz for 4G. The Network operator advertises the speeds up to 150 Mbps but you seldom get speeds up to 50-60 Mbps as there are a number of constraints; but still for me it's great.

Yes I rely totally on 4g at home as I live in the country & cant get landline broadband. We get a very respectable 45 DL and a ping of about 40ms (£27.50 for 50GB). The modem is good because it helps creates a network which I connect to TC & Airport express daisy chained with cat 6 for a 'roaming' wi-fi network around the house, it works well, very luck really 1.75 miles from mini cell, good line of sight. Also EE use Huawei hardware on their 4g cell towers.
