Glasgow-born Mr McKinnon, 43, who has Asperger's syndrome, is accused of breaking into US military computers.
Hackers have traditionally targeted government and military computers, but in recent years have expanded their efforts into the commercial sector.

Mr McKinnon, from north London - who hacked into the military computers in 2002 - has been fighting extradition since 2006.
Last October, British Home Secretary Theresa May rejected a U.S. request to extradite Gary McKinnon, a British computer hacker who has admitted accessing American military computers.
If convicted, Mr McKinnon, who admits hacking US military computers but says he was looking for evidence of UFOs, could face up to 60 years in jail.
That's because fewer attacks have been designed to infiltrate Mac computers, and adding more Macs to the military's computer mix makes it tougher to destabilize a group of military computers with a single attack, Wallington says.
Its immediate objective should be to validate and bring to bear automated techniques for addressing in the most cost-effective and least time-consuming manner possible the most daunting challenge: Making the Nation's civilian (government and private sector) and military mainframe computers Year 2000-compliant.

Its mission was redefined several times, and it was finally seen as a way to test the use of computers in military combat information systems.
In one case, McKinnon allegedly crashed computers belonging to the Military District of Washington.
The military drove the development of the earliest computers such as the ENIAC, seeking faster, more accurate ways to perform mathematical and scientific calculations.
Wallington, a division chief in the Army's office of enterprise information systems, says the military is quietly working to integrate Macintosh computers into its systems to make them harder to hack.
As a conductor of light beams, a given volume of the fibers can carry many times as many impulses as a similar volume of copper wire, and may eventually obsolete the latter in telephone communications--as well as in computers, aircraft and for many military purposes.
C4ISR is military jargon for command, control, communications, computers, intelligence, surveillance, and reconnaissance.
Military procurement has long been driven by cost and availability of additional software--two measures where Macintosh computers have typically come up short against Windows-based PCs.
