If the problem is minor you can start in Safe mode that will correct some minor issues. You can open the terminal and use the fsck -fy to check repair the disk.
If the MBP boots in the Recovery mode using cmd-r then follow that process to restore your OS installation, or use the Disk Utility to check/repair the disk. If problems reoccurs get another USB stick with minimum of 8 Gig capacity (not partitioned). 30%.100%.Ĭopying installer files to disk…(this part can take 30 minutes) sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia -volume /Volumes/Mavericks -applicationpath /Applications/Install\ OS\ X\ Mavericks.app -no interaction.Įrasing Disk: 0%. This can be done from the Erase tab within the app make sure the USB drive does not have multiple partitions (that can happen, so turn to the Partition tab to verify and correct this). I used this proces to make a bootable USB:įormat it, using Disk Utility, as a Mac OS Extended (Journaled) drive, named Mavericks. To create a bootable USB you will need a Mavericks Installer package from Apple Store the 5.5 Gig file saved to MBA- but not run.
We are dealing with 2 different problems.
