Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

There are some programs that require a case-sensitive filesystem, and others that require case-insensitive. Even though Apple warns against using case sensitive file systems, in some situations it is useful.

What programs have trouble with Case Sensitive (HFSX) systems?

What are the work-arounds?

In general, the problem is that the developers have a file in their app called FOO, but try to access the file by the name foo. In an HFS+ system that is case preserving but case insensitive, searching for foo will find FOO. That is not the case in HFSX. The general solution is therefore to

  1. Find the misnamed file or folder
  2. Make a copy, a link, or rename so the expected name is found

No ability to add answers, but this site lists some software and provides explanations how to debug and get them working again: jms1.net/osx-case-sensitive-fs.shtml –  user588 Jul 29 '12 at 23:48

The meta discussion has no objections lodged to re-opening this, so I'm going to over-rule the closure and ask that people join us on meta if I missed an opinion / reason to close it. Discussion is here and here –  bmike Oct 14 '12 at 16:39

According to this question, Photoshop CS5 won't work on HFSX.

Convert a partition from case-sensitive to case-insensitive

Apparently, CS6 doesn't work, either. apple.stackexchange.com/questions/61665/… –  CajunLuke Aug 22 '12 at 20:54

Thing (beta, 1.6b24) does not work with HSFX. The solution is to rename or link the Versions folder to versions

cd Things beta.app/Contents/Frameworks/CulturedRuntime.framework
ln -s Versions versions

MeshLab version 1.3.2 does not work on HSFX systems. The CFBundleExecutable in Info.plist specifies MeshLab, but the binary in the Contents/MacOS folder is meshlab. The solution is to edit Info.plist (change MeshLab to meshlab) or:

cd meshlab.app/Contents/MacOS
ln -s meshlab MeshLab

A bug report has been filed here: https://sourceforge.net/p/meshlab/bugs/323/

The CrashPlan backup software (v 3.6.3) has a known case sensitive issue.

Solution is:

  1. Open Terminal
  2. Stop the CrashPlan service by entering this command:

    sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist

  3. Open the CrashPlan plist file by entering this command:

    sudo nano /Library/LaunchDaemons/com.crashplan.engine.plist

  4. Enter your password for the computer when prompted

  5. Locate the following string:

    <string>/Applications/CrashPlan.app/Contents/MacOs/CrashPlanService</string>

  6. Update it to (note capital s on MacOS):

    <string>/Applications/CrashPlan.app/Contents/MacOS/CrashPlanService</string>

  7. Press Control+X to exit

  8. Press Y to confirm the changes
  9. When you see the prompt File Name to Write, press Enter to save to the existing location
  10. Start the CrashPlan service by typing:

    sudo launchctl load /Library/LaunchDaemons/com.crashplan.engine.plist
