fixed : a (relatively) quick fix for Photoshop not wanting to install on Case-sensitive formatted HD

Question :

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 ?

Answer :

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 !

    • @sunbit :
      Thanks for the alternative solution !
      That might be a good solution for some also.

      Note :
      Personally I would still recommend the reformatting-solution I’ve mentioned in my post, since I have a slight doubt about the stability of the alternative you’re suggesting…

  1. 1. Purchase and install iPartition ($70, but worth it if it’s your only solution)
    2. In iPartition, do a Create Boot Disk
    3. Insert your installer disk to make a boot disk from it
    4. Insert blank DVD-R to create boot disk through iPartition
    5. Restart computer, with boot disk inserted and holding “C” key on keyboard until progress spinner thing shows at start-up
    6. iPartition should automatically load. Choose “Make Case Insensitive” from one of the drop-down menus
    7. Let it complete this process…
    8. Quit iPartition and allow computer to restart, now from your “Case Insensitive” hard drive
    9. Install Photoshop as normal
    10. Drink beer. Celebrate.

      That might be a good solution for people that don’t mind about the fact that iPartition is rather expensive software…

      Note :
      Personally I would still recommend the reformatting-solution I’ve mentioned in my post, since by using (and buying) iPartition you are getting a quick fix, but not a ‘future-proof’ solution :
      buying iPartition will initially cost you €41 at this moment (or $45, which is cheaper than the $70 you’re mentioning – you probably purchased some time ago…),
      but by the time you will need it again (by the time you upgrade Photoshop and/or OSX) it’s almost certain that you will need to upgrade iPartition again to be able to use it (any new upgraded version of OSX usually means incompatibility with previous versions of all partitioning, defragmentation, virtualization and comparable software…)
      and an iPartition upgrade will cost you again €20…
      and that practice will repeat itself until you ‘just’ reformat your entire primary drive…
      …so if you already have iPartition since you regularly need to use it, it’s good to know you can also use it in this case,
      but I would not recommend it to just fix this problem, for that it’s just a way-too-expensive ‘one trick pony’…

      Enjoy !
