just received lightroom yesterday and tried to insert and install on my mac running os10.10...the disk is comparable with windows and mac...it spins around for a bit and then spits out disk...any help?
Open the disk using Finder and see if you can start the installer. Or, you could download the trial version and activate it with the serial number included in your package.
Adobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 5.7
