MacExpo will take place at London's Business Design Centre, in Islington from November 22-24.
The event is independently run for UK Macintosh users, and follows last year's event at the same venue, which received a positive reaction from the public and industry alike.
The list of confirmed exhibitors already includes Macromedia, Epson, Hermstedt, Iomega and OKI Systems.
Desktop publishing giant Quark has also pledged to appear at the event, prompting speculation that the company may demonstrate QuarkXPress 5.0 at the show. XPress 5.0 has been in beta testing for several weeks.
The organisers have already opened the books for online pre-registration. Potential exhibitors should be aware that the Web site has no link to book stalls.
