There are many ways that you can create a bootable Mavericks USB Drive but this seems to me the far easiest way to do so. In this article I will assume that you already have a reasonable grasp of the OSX system and cut out the lengthy text:
1. Download Mavericks
Mavericks can be downloaded directly from Apple here (make sure you leave the file in the default download location)
2. Prepare a USB Flash Drive (Must be 8Gb or larger)
- Download Messenger For Macbook Pro 10.9.5 Pro; Download Mac OS X Mavericks 10.9.5 free latest version offline setup for MacBook. Mac OS X Mavericks 10.9.5 is a powerful operating system with a variety of enhancements and a variety of new features that delivers more stability and ultimate level of performance.
- MacBook Pro, iOS 7.0.3 Posted on Oct 26, 2013 1:46 AM. Both my OS 10.7.5 and OS 10.6.8 macs won't download Mavericks, or in one case, seems to be downloading but.
- Plug the USB Drive in to your Mac and open “Disk Utility” (found under applications / utilities in finder)
- Select the USB Drive
- Select the Erase tab
- Ensure that the format is Mac OS Extended (Journaled)
IMPORTANT – Leave the name as “Untitled”. If you change this the next step won’t work
3. Create the Bootable Mavericks USB Drive
Open up Terminal (found in applications)
Here is a Sierra download link. List of Apple computers compatible with macOS Sierra. MacBook (Late 2009 or newer) MacBook Pro (Mid 2010 or newer) MacBook Air (Late 2010 or newer) Mac mini (Mid 2010 or newer) iMac (Late 2009 or newer) Mac Pro (Mid 2010 or newer) OS X 10.11 El Capitan. Last OS X version. Release date: September 30, 2015.
Type this in:
sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X Mavericks.app –nointeraction
Wait for the process to complete. Done.
4. Boot from the Mavericks USB Drive
Restart your computer and hold down “Option”. You can now select the USB Drive you just created.

Apple has released OS X 10.9 Mavericks, and somewhat surprisingly it is a free upgrade for all existing OS X users. If you’re using a Mac laptop or desktop from the last five years or so, you should be able to download OS X Mavericks for free just by visiting the Mac App Store. Some exclusions and caveats do apply, though, so read on for more information.
Downloading and installing OS X 10.9 Mavericks for free
Before you upgrade to OS X 10.9 for free, the most important question is whether your Mac hardware is compatible. In general, if you’re already running OS X 10.6 Snow Leopard, you should be able to install Mavericks. Here’s a complete list of Mac laptops and desktops compatible with OS X 10.9 Mavericks:
Mac Os X Mavericks Installer Download
- MacBook Pro (mid/late 2007 and newer)
- MacBook Air (late 2008 and newer)
- iMac (mid 2007 and newer)
- MacBook (late 2008 aluminium, or early 2009 and newer)
- Mac Mini (early 2009 and newer)
- Mac Pro (early 2008 and newer)
- Xserve (early 2009)
Before you begin the upgrade process, you should save and close any open programs. If you’re upgrading some older Mac hardware, you might also find it useful to clear up your hard drive first, by uninstalling unused apps, transferring large files to external storage, and using a clean-up tool such as CCleaner.
If you have Snow Leopard, Lion, or Mountain Lion installed (10.6, 10.7, 10.8), upgrading to 10.9 Mavericks is as simple as heading to the Mac App Store, clicking the huge OS X Mavericks banner, and clicking “Install.” It will download the update (which is around 5GB), and then ask whether you want to begin the installation process. Once you begin the installation, that’s it: It’s a one-step installer without any “next” buttons.
For me, on a fairly bogged-down 2011 MacBook Pro, the free upgrade to OS X Mavericks took around 90 minutes. On a newer and fresher systems, it should be a lot faster.
After installing OS X Mavericks…
Once the installation process is complete, a notification will pop up offering to teach you about Mavericks’ new features. You should probably click it, especially if you’re coming from Snow Leopard or Lion as quite a lot has changed. The most exciting new features in Mavericks are probably the iCloud Keychain, Notifications tweaks, and some cool low-level tech that should improve battery life and performance (Timer Coalescing, App Nap, and Memory Compression). If you’ve always wished for iBooks, Maps, and Calendar to make the leap from iOS to your Mac, you’re in luck, too.
