Last change on this file since 593 was 342, checked in by rchin, 17 years ago

Leopard compatibility changes:

  • Removed some icon caching code that was causing crashes (not sure we really needed those optimizations anyway -- doesn't appear to affect performance)
  • Added code to automatically try to add certificate to keychain, for new code signing behavior (replaces previous procmod nonesense).
  • Note that the enclosed public certificate is mine, and so it will need to be signed by me. In the case that someone else wants to distribute this binary, please replace Certficiate.cer with your own public certificate, and then make sure o code sign the binary after it is built.
