Adobe Photoshop Lightroom 5.7 and Mac OS X – will no longer open

After upgrading Lightroom 5.6 to 5.7, it refused to open with the error:
  Library not loaded: @executable_path/../Frameworks/asneu.framework/versions/a/asneu
  This problem stems from the fact that the system drive is a case sensitive file system; in a similar vein, we were recently unable to install Adobe CC on a similar system as it is also incompatible with a case sensitive file system. We fixed our Lightroom issue by changing the path from:  
/Applications/Adobe Photoshop Lightroom 5.app/Contents/Frameworks/asneu.framework/Versions/A
  to:  
/Applications/Adobe Photoshop Lightroom 5.app/Contents/Frameworks/asneu.framework/versions/a
  The above assumes a normal install to the /Applications directory. If you are game to try the change yourself, you make the change via Terminal:  
cd /Applications/Adobe\ Photoshop\ Lightroom\ 5.app/Contents/Frameworks/asneu.framework sudo mv Versions versions cd versions sudo mv A a
  Now try and start Lightroom and you should be successful.

Lightroom 4: “Sort” option/dropdown box missing from Library view

  This one isn’t related to computer parts for a change but is something that happens to me regularly – I’ll import a handful of photos and want to sort them by capture time, but the “sort” box is missing from the Library view in Lightroom 4.0. You can bring it back by pressing T.   I don’t know how it is I keep on accidentally hitting T but it seems I must do so regularly judging by how often this happens…
