Apple's AppleSeed program allows a select group of customers to test out Apple software before it's even released to Apple's registered developers. These select customers received an email from Apple on Wednesday, informing them that the company is preparing for 'hardware specific software updates'.

9to5Mac reports that the email reads: "We are preparing for possible hardware specific software updates on OS X Mountain Lion. These contain hardware-specific bug fixes or even special features! In order to make sure you can participate in these exclusive seeds, we need your most up-to-date machine configuration information. The easiest and most efficient way to do this is with Feedback Assistant."

Apple could be referring to Macs with Retina displays when it talks about 'special features'. It has been reported that Apple will be launching new Macs with high-resolution displays at its WWDC in June.

Last week, we reported that Apple has seemingly been preparing its operating systems for high resolution Macs, after Retina ready icons were spotted in a recent OS X update.
