Apple on Wednesday pulled its last-generation OS X Lion from both the Mac App Store and brick-and-mortar Apple Stores amid the launch of OS X 10.8 Mountain Lion OS.

As OS X 10.8 Mountain Lion rolled out today following Apple CEO Tim Cook's impromptu launch announcement during Tuesday's third quarter conference call, the company took down all mentiion of the last-generation operating system from its digital storefront while simultaneously removing OS X Lion USB thumb drives from physical stores, reports CNET.

Users attempting to find Lion on the Mac App Store are met with a "product not available" message while those who purchased the last-generation operating system can no longer re-download the software via the previous purchases section.

The publication notes that Apple has traditionally pulled older versions of its Mac OS when a new iteration is released, but in the case of Lion it could cause problems for users who want to upgrade to a newer operating system but have hardware that is incompatible with Mountain Lion. While such owners, limited to certain Mac models made between 2006 and 2008, have had a year to upgrade to Lion, feet-draggers may be out of luck unless they buy the OS through a reseller.

Apple has yet to issue an official statement regarding the matter.
