Numerous sellers found in the AppleInsider Mac Price Guide are currently out of stock of the Mac mini. Specifically, for the 2.3-gigahertz model, stock-outs are seen at Amazon, MacConnection, and J&R, while the 2.5-gigahertz option is unavailable at Amazon, MacMall, MacConnection and J&R.
Supply of the Mac mini Server with a 2-gigahertz Core i7 process is also running dry, as Amazon advertised as of Monday that it only has a few units left in stock, while MacMall and MacConnection are currently sold out.
In addition, Macerkopf.de noted on Monday that supply of the Mac mini has also begun to run dry in Germany. Apple typically winds down its inventory ahead of a new product launch, and limited supply at third-party resellers is often one of the first signs that a hardware refresh is forthcoming.
However, supply fluctuations are not always a sign that a hardware refresh is imminent. For example, Apple's iMac has seen its availability remain constrained off and on since July, but the all-in-one desktop has not yet been updated.
An updated Mac mini was not listed by analyst Ming-Chi Kuo among the eight new products Apple is rumored to launch this fall. However, he did indicate that Apple is planning to debut a new 13-inch MacBook Pro with Retina display, as well as redesigned 21.5- and 27-inch iMacs.
Apple last updated the Mac mini in July of 2011, adding support for the high-speed Thunderbolt port while ditching the built-in optical disc drive that had been found on previous models. The current Mac mini lineup starts at $599 and features Intel's previous-generation Sandy Bridge processors.
