In a note to clients — as reported by “AppleInsider” ( — KGI Securities analyst Ming-Chi Kuo — thinks the new iMacs will quadruple Apple’s desktop sales.

The analyst predicts that Mac desktop shipments will be down to 264,000 for the company’s fourth fiscal quarter of 2012. That’s a 79% dip from the year-ago period.

Kuo has reduced his forecast of Mac desktop shipments by over 63 %, mainly due to the new iMac’s later-than-expected arrival, notes “AppleInsider.” Despite this, he thinks iMac shipments will pick up during the holiday season, growing 434% quarter-on-quarter mostly thanks to expected strong demand for the revamped iMac that Apple announced yesterday. The 21.5-inch model hits the stores in November; the 27-incher in December.
