Today, I wanted to install Photoshop on my Mac, but the installer refused because I have my Mac HD formatted in “MacOS Extended (Journaled, Case-sensitive)” format.
How can I easily fix this ?
Photoshop (both Photoshop Elements and Photoshop CS) can not be installed on a Mac that has a “MacOS Extended (Journaled, Case-sensitive)” formatted internal HD. It just can’t. There is only one route to fixing this that will help here : you need to reformat your HD.
So here’s the quickest way to reformatting and restoring your Mac’s internal HD without loosing data :
– make a Time Machine backup of your HD
– plug an OSX 10.7 installer (USB-stick or DVDrom) into your Mac
Note : if you don’t have an OSX-installer, here are directions on making one :
– make sure you have a new DVD-writable or a completely empty 4GB USB-stick
– download Lion Disk Maker and follow the instructions that come with it :
– restart while pressing the ALT-button
– choose the OSX EFI volume to boot from
– open Disk Utility
– click on the Erase tab
– select your internal HD, and “MacOS Extended (Journaled)”
[ and NOT “MacOS Extended (Case-sensitive, Journaled)” !!! ]
– click Erase (a new name for the HD is not important)
– when the erase (reformat) is finished, exit Disk Utility and go to “restore from Time Machine backup”
– make sure your Mac is connected to the Time Machine disk by a cable connection (either Ethernet/UTP, USB or FireWire)
– select the volume called Data and continue
– select the subvolume that has your previous HD’s name
– click Restore and wait
(restoring can take up to one hour)
– afterwards restart your Mac normally
– do a quick check to see if things work properly
– put in the Adobe Photoshop Elements installer DVDrom and follow the installer instructions
– done !
