Steps to install Mac 10.9 beta, (Mavericks)

Steps to install Mac 10.9 beta Mavericks

Step 1:
                Check for your Mac device, so that your device supports Mavericks.
                The Mac OS X v10.9 Mavericks supports the following Apple Macs devices:
·         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), (15-inch, Mid/Late 2007 or later), (17-inch, 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)
(if your computer uses an Ivy Bridge processor, be sure to use iBoot for Ivy Bridge)
Step 2:
                 Download the Mac 10.9 Beta (Developer preview  1) from this link
Step 3:
                Make a bootable disk, steps as follows,
o    Attach the USB drive to the Mac and launch Disk Utility
o    Choose the USB drive from the left side menu, click the “Partition” tab, select “1 Partition” from the drop down menu, and then click the “Options” button to select “GUID” as the partition type, click “OK” then click “Apply”
o    Launch Terminal to show hidden files and relaunch the Finder using this defaults command string:
defaults write AppleShowAllFiles TRUE;\killall Finder;\say Files Revealed
o    Go to the /Applications/ folder to locate the “Install OS X 10.9 Developer” file
o    Right-click and choose “Show Package Contents”, then open “Contents” and open “SharedSupport”

o    Double-click to mount “InstallESD.dmg”
o    Open the mounted ‘OS X Install ESD’ image, and right-click “BaseSystem.dmg” choosing “Open” to mount the image (BaseSystem.dmg is invisible by default, thus why invisible files must be made visible in the earlier step)

o    Go back to Disk Utility, then select “BaseSystem.dmg” from the sidebar and then click the “Restore” tab
o    With “Source” set to “BaseSystem.dmg”, set “Destination” to the USB drive by dragging the USB drive into the box, then click “Restore” to begin – confirm that contents of the drive will be erased

o    When finished, go to Finder and navigate within the newly created USB drive to System > Installation > and delete the file (alias) located here named “Packages” – keep this window open

o    Go back to the ‘OS X Install ESD’ mounted drive, and drag & drop the “Packages” folder into the /System/Installation/ directory you just deleted the Packages alias from, let this large folder copy

o    Once that Packages folder is finished copying to the drive, the USB drive is now ready to be booted from which it can install OS X Mavericks from.

Step 4:
                Yess!!! Boot from bootable disk. Steps needed?
                Here are they……
o   With the USB drive attached, reboot the Mac and hold down the Option key
o   Select the orange drive, labelled “OS X Base System 1″ from the boot menu
o   Proceed with the installation as usual

o   Enjoy OS X Mavericks!

You can also dual boot it along with OS X (10.8 r 10.7 r whatever you have installed!!)

Setting up a dual-boot environment for OS X Mavericks and OS X 10.8 (or even 10.7 and 10.6 if you’re still running an older version of Mac OS X) is easy and allows for a fresh installation of Mavericks to test and develop with. Because the original OS X installation remains untouched, it’s also the safest way to give Mavericks a trial run, which is perfect for running the Developer Previews or if you’re just not sure you’re ready to run OS X 10.9 full time yet.
You don’t need another hard drive to be able to do this, instead you utilize unused space on the existing drive to create a new partition that runs the alternate OS. This process can be completed from a Mavericks boot drive if desired, and using such an USB installer tends to prevent any potential errors with Disk Utility (more on common errors you may encounter at the very bottom of this article), but it is not necessary.

Be sure to back up the Mac before modifying the partition table, the easiest way to do that is by starting Time Machine immediately rather than waiting for the scheduled backup to take place. Let that complete before beginning.
o   Partitioning & Installing OS X Mavericks for a Dual Boot Mac
o   Launch Disk Utility, from /Applications/Utilities/
o   Select the hard drive from the left side menu, then choose the “Partition” tab
o   Click the [+] plus button to add a new partition, size it to at least 12GB and name it something logical, like “Mavericks”, then click “Apply”

o   Quit out of Disk Utility when finished.
o   At the installation menu, choose the “Mavericks” partition you created as the destination drive, then choose Install (you may need to click “Show All Disks” for the partition to show up)
o   OS X Mavericks will install and, when finished, will boot directly into 10.9.
To switch booting between OS X versions, restart the Mac and hold down the Option key, then choose whichever partition you wish to start up from. You’ll notice the initial boot menu does not display the OS X version, which is why it’s important to name the partitions something fairly explanatory, like “Mavericks”. You can also change the bootdisk by going to “Startup Disk” within System Preferences and selecting the OS X partition to use, the preference panel option will display the OS X versions for each partition.
