Please, safe yourself and don't post this kind of comments. Works for me, works for other people. If you have a problem be patient and wait for respond from somebody.


OS X will not install on Macintosh HD drive as there is a problem with partition or system on this partition. Read this artile and follow instrucitons from it: http://support.apple.com/kb/TS1417.


And small advise - before you do anything create yourself a backup of your data. Just in case and before is to late.

I'd like to add my voice to those who cannot get Mavericks to work. I have a 20" early 2008 iMac with 4GB RAM and 60 GB free space on my Macintosh HD. The download from the Apple Store went well and I have an "Install OS X Mavericks" file (5.31 GB) in my Applications folder. Mavericks seemed to install but, when it finished, the Desktop was grey with no icon and none of my programs would run. The install was over a functioning OS 10.8.5 and Macintosh HD passed verification with Disk Utility and I repaired permissions before the install. Fortunately, I cloned my Macintosh HD with SuperDuper prior to installing Mavericks so no data was lost. I did the installation twice with the same result each time then I gave up and reverted back to OS 10.8.5. What is going on? Mavericks needs some serious repairs. I've never has an OS upgrade do this.
