The trial version downloaded fine but when I went to open it it said that it is not compatible with my imac 10.6.8. Any suggestions?
10.6.8 is the minimum requirement for Lightroom 4. Can you provide a screenshot of the error or the exact error message? Which Macintosh computer are you using? What processor is it utilizing? You can find the processor information under About This Mac.
Hi Jeff. I have 10.6.8.
|Processor Name:||Intel Core Duo|

Ah yes this is because you have a single core iMac and Lightroom requires a multi-core processor. You can find more details at http://www.adobe.com/products/photoshop-lightroom/tech-specs.html.
