The last quarter appears to be a very busy time for the Cupertino tech-titan, with earlier reports suggesting a larger 12.5-inch iPad Pro coming out in November. Now, the much-rumored iMac with 4K Retina display is also expected to start shipping during the same month.

According to a report by 9to5Mac, information from “reliable sources” indicate that Apple plans to launch the iMac 2015 along with the OS X El Capitan by end of October.

The 21.5-inch iMac is probably arriving with a 4K Retina screen and could be running the beta version of the upcoming – OS X El Capitan. Last fall witnessed the 27-inch iMac being blessed with a 5K display, and it only seems fitting that its smaller variant should receive the makeover of sorts.

The new iMac may sport a screen resolution of 4,096 x 2,304 which is a major enhancement from the current 1920 x 1080, and may come embedded with an upgraded AMD Radeon R9 processor, as noted by Tech Radar.

The iPad Pro may just also be announced at the grand event on Wednesday and the new tablets may go up for pre-order on October and begin shipping in November. The new iPad is rumored to be the largest offering till date in the tablet category with a 21.9-inch display from Apple.

If the launch information is to be believed, then the 21.5-inch iMac with 4k Retina display resolution should start shipping in the beginning of November. All the upgrades are bound to add to the cost, more so with the addition of the high-end display.

While there has been no word on the price of the new iMac, the current 21.5-inch models are retailing for up to $1499. Fans could expect to be shelling out a tad bit more to get their hands on the upcoming Apple PCs.

Come September 9 and all the doubts about all the products including the new iPhone, iPad and now the smaller iMac would clear up.
