Lightroom 2.x runs on 64-bit mode

screencap_20090102_1In case you don’t know (cause I dont), Adobe Lightroom 2.0 runs on 64 bit mode natively in OS X. I was fiddling with my apps folder and was curious about what i saw (see left photo) . So i checked out and confirmed it is running on 64-bit mode

See Adobe’s feature highlights below

Top new features

  • Local adjustment brush
  • Enhanced organizational tools
  • Volume management
  • Extensible architecture
  • Revolutionary DSLR profiling
  • Multiple monitor support
  • Flexible print package functionality
  • Streamlined Photoshop CS3 integration
  • Enhanced output sharpening
  • 64-bit support for Windows® and Mac OS

And so if your LR is not permforming optimally try ticking that check box “open in 32 bit mode” (see photo above) this might solve your speed issues.
