Apple is expected to launch a 13in MacBook Pro with Retina display in September, alongside a new iMac lineup.

That’s according to KGI analyst Ming-Chi Kuo, who predicts that the new Retina MacBook Pro will join the recently launched 15in MacBook Pro with Retina Display at some stage in September this year, he revealed in a note sent on Monday.

Kuo warns, however, that demand for the smaller Retina-resolution MacBook Pro could outweigh supply, because the display’s components are limited.

“We think consumers who initially planned to purchase the 13in MacBook Pro and Air will turn to the 13in Retina MacBook Pro instead because it has an attractive panel, its price is similar to the MacBook Pro and it has better balance between power consumption and form factor,” wrote Kuo. “However, as supply is limited due to panel and assembly yield rate issues, shipment of the 13in Retina MacBook Pro won’t be able to satisfy demand.”

“We think consumers’ budgets will transfer to new iOS products after Apple launches them, which suggests that overall MacBook shipments will not grow meaningfully on the 13in Retina MacBook Pro,” Kuo concluded.

Kuo also believes that an Ivy Bridge iMac lineup has been delayed following screen lamination issues. “The chances of the new iMac debuting in September are slim. But, judging by the current supply chain situation, it could be rolled out by end-September,” he said. “[Supply chain] shipments for Mac desktop models will be low due to inventory adjustment in July, and will see the most dramatic month on month rise in August as shipments for the new iMac begin.”

Earlier this month, we reported that the iMac is said to be in short supply, suggesting that a refresh may be imminent. But developers have suggested that the next iMac might not have the Retina display that many are expecting. The September arrival date for the new iMac is in keeping with previous reports that the desktop Macs will arrive before the iPhone 5, which is expected to launch this autumn alongside iOS 6.

In the same note, Kuo also predicted that Apple will launch the iPad mini, an internally updated 10in iPad, the iPhone 5 and new iPods in September.
