However, don't get too excited, as the new Macs are most likely to feature minor internal upgrades.

According to French site Mac Generation, Apple is planning to refresh the computers in much the same way it did its MacBook Air notebooks earlier this year.

In April, without any fanfare, Apple updated the internal components of its lightweight notebooks, upping processing power and battery life and shaving $100 off their price tags too.

And now it looks as if the company intends to do exactly the same thing with its desktop range. So better processors and potentially more RAM and, crucially, a slight price drop.

Therefore expect the 21.5-inch and 27-inch desktops to get a 100Mhz processing upgrade and support for Thunderbolt 2 connectors but if you were hoping for an all-in-one with a Retina display, you're probably going to have to wait a bit longer.

Mac Generation was the first site to get the drop on Apple's plans to update its MacBook Air computers and trim their price tags and so its claims regarding the iMac are worth taking seriously.
