Flash Disk For Mac
A bootable Mac OS X thumb drive comes in handy when you need to troubleshoot OS issues for yourself, your family, or your friends. Its also extremely useful for keeping your basic setup consistent across multiple computers, if you find yourself switching hardware regularly; and Ive had fun in the past setting up a bootable USB keychain loaded with all the apps and files I need to turn any Mac-compatible computer into a viable media center quickly and easily.
With Mac OS X Lion and a new piece of free software, its easier than ever to create a USB keychain that you can boot from. All you need is a few minutes, a copy of Lion, and a USB flash drive with at least 4GB of storage (though more is preferable).

As we all know, USB flash drives are widely used for storing and transferring data from an iMac, MacBook or Mac Mini, though newer MacBook Pro and Air uses no USB 3.0 port. 'I have a 32 GB USB which has suddenly come up with a message stating the USB flash drive is not readable by this computer (Apple MacBook Pro).
Format drive for Mac: In Disk Utility, go to Partition Volume Scheme 1 Partition. Create volume name, choose Options GUID Apply. In Lion SharedSupport folder, copy and drag.dmg file to Disk Utility Source. Drag volume to Destination Erase Destination Restore. To boot: Insert flash drive in Mac and restart. Hold Option key while. Preparation Flash Drives For Mac Computers
Instead of using the system installer disc that came with your Mac, create a system installer flash drive, like the one that comes with the MacBook Air. It's smaller than an optical disc, more. If you want to use your USB stick with an Apple Mac, you will need to restart or power-on the Mac with the USB stick inserted while the Option/alt () key is pressed. This will launch Apples Startup Manager which shows bootable devices connected to the machine. Flash Disk For Mac Os
The first step in getting Lion onto your USB drive is to obtain a copy of the OS itself. Unfortunately, the file you download from the Mac App Store to your computer deletes itself after you update to Lion, so youll probably need to re-download the OS update.
This is a simple but slightly time-consuming process. Go into the App Store application and open the Purchases tab at the top of the screen. From there, you should see OS X Lion as one of your previous purchases.
Click the Download button next to Lion, note the directory that it downloads to and wait for the download to finish. During testing it took me about 50 minutes to re-download the 4GB or so of content that comprises Lion.
Once the OS has finished downloading (and youve verified that Lion has landed safely in your Applications folder), youre ready to transfer it to your trusty USB flash drive.
If you already own a copy of OS X Lion, you should be able to download a fresh copy at any time from the Purchases tab of the Mac App Store.
To streamline the process, download the free Lion DiscMaker app. Downloading a third-party app just to handle this process is a bit of a bother, but Lion Discmaker enormously simplifies the process of installing Lion on a USB keychain.
Now, before you start formatting your drive, back up anything currently on your flash drive that youd like to keepbecause this process will completely erase the contents of the USB drive and rewrite it with a copy of Lion. You have been warned! Creating Your Bootable Drive
Lion DiscMaker makes this part of the process a snap. Start the Lion DiscMaker app with your USB flash drive plugged in and with the Lion install file sitting inside your application folder. The app will give you the option of creating a bootable drive out of either a DVD or a USB keychain.
Select the USB keychain option. (If you happen to own a Mac with a disc drive, consider creating a DVD backup of Lion. I prefer keeping Lion on a USB keychain so that I can add files to the USB drive to customize the installation; but if youre just looking for a bootable copy to troubleshoot your hardware, feel free to go with the DVD option and save yourself a little cash.)
Lion DiscMaker makes it easy to create a bootable thumb drive.
Once youve indicated that you want use a bootable drive, the app will ask whether youd like to use a USB thumb drive or some other kind of disk. Select the USB thumb drive option again; and when prompted, choose the disk that youd like to install Lion to. Select your flash drive and you should be ready to rock.
If youre using a thumb drive that has only 4GB of free space, Lion DiscMaker will remind you that you wont get a complete of OS X Lion package because there wont be room for the additional speech voices package. This should be no great loss. Select Okay and then, to confirm that youre aware the volume will be erased, click the Erase then create the disk button.
The copy procedure will take a few minutes and will open a few windows in your finder automatically, but Lion Discmaker should automate the whole process. All you have to do is wait for your Mac to cease displaying its Copy in progress, please wait message, which will indicate that DiscMaker has finished installing Lion onto your flash drive. Once thats done, youll have a bootable USB flash drive that fits in your pocket and can handle system recovery, OS installation, and even basic Web browsing in a pinch.
If you have any space left over on your flash drive, you can add a few of your favorite applications and files, to customize a new installation. Regrettably, these files wont be accessible when you boot directly from the USB flash drive; but once the installation is finished, they can help you save considerable time while setting up a new computer.
Of course the bootable drive that this method creates is no substitute for a fully customized Mac OS X Lion-based computer, but considering how fast and easy the drive is to set upand how much time it could save you the next time you need to reinstall or troubleshoot your Mac OS Xtheres no good reason not to make your own bootable copy of Lion to carry in your pocket. Good luck! Search recipes for this entry:
