I had upgraded to 16Gb a couple of years ago fitting Crucial Memory (less than a 10th of the price of buying from Apple).
#REINSTALL OSX INSTALL#
My last resort, after 3 days, was to buy a new SSD to install on – this also failed! I then stumbled across a reference on the apple support site that sometimes 3rd party RAM can cause problems during installation, even if the RAM is fine. This tutorial to make the bootable USB was invaluable in the end, but did not resolve the issue.
#REINSTALL OSX UPGRADE#
After trying to upgrade to Mavericks (from Snow Leopard) I could not successfully install anything. Just thought I would add something after fighting with ANY installation of MacOSX on my (mid2011) 27″ IMac. If you run into any issues with it, leave a comment and I’ll help ya get squared away.
Remember, to rehide the normal hidden files just repeat step 1 but change YES to NO.Īnd by Jove, that works! So for all of you that were either too broke to upgrade or just never made it past 10.6.8, this should be your salvation. If you only have 1 USB Port and it’s being used by your mouse (I’ve encountered this a few times in our shop at the office) you can get a USB hub here. So simply restart, hold down the Option key (Alt) when booting with the USB drive in your machine, and you should get the option to boot from the USB drive. Basically, replace the Packages alias you just deleted with the real Packages folder from the original InstallESD volume. #REINSTALL OSX FULL#
Copy the full Packages folder from the root of the mounted InstallESD volume (the same place you got the BaseSystem.dmg file) to the USB volumes System/Installation folder. In there you will see an alias for Packages. Now open up the restored USB volume (default name is OS X Base System) and navigate to System/Installation. Open Disk Utility and restore the source BaseSystem.dmg to the destination of your USB drive. You should now see the normally hidden BaseSystem.dmg file in the mounted volume. Unfortunately, you can’t just grab it and restore it. There you will see the InstallESD.dmg file. Navigate to the Contents/SharedSupport. Right-click it and select ‘Show Package Contents’. #REINSTALL OSX DOWNLOAD#
After download you will have the ‘Install OS X 10.9′ app in your /Applications folder. (At time of writing this is only possible for those with access to the developer previews). Download the installer as normal from the app store. So start by opening Terminal.app and pasting in the following (don’t worry, we’ll undo this change when we are done)… defaults write AppleShowAllFiles YES You are going to need to see some hidden files for this. You will need at least a 8GB Flash Drive (USB 3.0 is obviously a better choice). The Marek Bell blog notes that creating a bootable flash drive of Mavericks is a bit more intricate than Mountain Lion because “it is no longer possible to simply restore the InstallESD.dmg to get a bootable image for USB / Flash drive installation.” But there is a way around this obstacle, which Marek outlines in his thorough walkthrough of creating a bootable OS X Mavericks flash drive. When I happened onto this post from 9to5Mac ( ) So I did some deeper digging because I wanted to get my iMac running 10.6.8 into the DANGER ZONE as soon as possible. ): sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ Mavericks.app (Terminal gave me the -9999 error)Īnd running a Script version of the Terminal option (with the same results. Running this in Terminal (courtesy of Nerd Answer. Error Message saying it had problems erasing the drive. Installing DiskMaker X ( ) – Didn’t work. The methods I tried that were suggested were: The error is this: When trying to use the multiple methods offered for creating a bootable thumb drive version of Mavericks (Requires a thumb drive 8GB or higher), you get this error: Failed to start erase of disk due to error (-9999, 0). 
I’ve seen a bunch of people running into the same errors that I did but no one had a fix. But for people that never got past OS X 10.6.8, we didn’t realize how much of an issue we would run into.

Let’s add Mavericks To A USB Drive, shall we?Īpple decided to break the mold and release OS X Mavericks for free through the App store.
