Apple has updated the price and processing power of its top-end Macbook Pro with Retina display devices.
Effective immediately the 128GB 13in Macbook Pro with Retina display will cost £1,249 while the 256GB 13in Macbook Air will cost £1,199. The amendment reduces the two device's upfront cost by as much as £200.
Apple also upgraded the processors in its 15in Macbook Pro with Retina display and notebook range.
The 15in Macbook Pro will now feature a faster 2.4GHz quad-core processor, while the top of the range 15in Macbook houses a 2.7GHz quad-core processor and boasts 16GB of memory.
Apple also announced a new 13in Macbook Pro with an improved 2.6GHz processor and 256GB will be available costing £1,449.
The price cuts and mid-lifecycle upgrades come during a turbulent period in the PC market and for Apple as its share price slumps as investors fear its market dominance is being undermined by competitor devices.
The release of Microsoft Windows 8 has seen competing PC makers to take an interest in touch computing.
That has led to speculation that Apple may be planning to add similar capabilities to its next line of Macbooks.
But many market watchers have noted that touch capabilities have done little to halt the decline in PC sales, as buyers switch to tablets.
On Tuesday Apple chief executive Tim Cook said the Windows PC market represented a huge opportunity for the firm to steal market share from its rivals.
