Apple seems to have an angle on creating new rumours, with a widely reported 'glitch' on its UK website last night sending out a wave of expectation that its top-of-the-line Mac Pro computers may be due an imminent upgrade.

Eagle-eyed Mac users spotted the UK Apple Store go offline last night. The store then reappeared and – it's claimed – briefly offered tantalising details of an as-yet-unnanounced new Mac Pro model.

If the claims are true, Apple is preparing to introduce 8-core Xeon processors as an option across its range of Mac workstations.

"Now quad-core or 8-core processing power. Configure yours today," said the store. However, the message was swiftly removed.

Intel yesterday launched a new range of quad-core Xeon processors (as used in the Mac Pro). The new chips use between 35 per cent and 60 per cent less power than its existing sever products.
