Microseconds was established in 1992 in association with the reseller Logical Solutions as a means of facilitating the disposal of previously leased equipment from government departments, small business and educational facilities. Microseconds offers a wide range of upgrades and repairs to Apple computers. We've been exclusively specialising in Apple computers for home, office and small business since 1999 under the watchful and thoughtful guidance of founder and human extraordinaire, Hugh McMullan.

Hugh has now left the building – in an Elvis kind of way but not as final! – and Nick has taken on the reins to ensure you continue to receive the care and attention you need for your Macs.

Our workshop is located in NORTH RYDE, near Lane Cove Road and the Macquarie Shopping Centre, with easy access to parking. See map on Contact page

The staff have knowledge about Macs, past and present, and will help you select the best option for your requirements and budget.

Every computer received from leasing companies is thoroughly tested and refurbished. Microseconds offers a 3-month back-to-base warranty on all its computer sales and repairs, and provides exceptional ongoing service and upgrades. We may also buy your old Mac computers or trade them in against existing stock.

In this site you will find all our current stock, special offers, and a range of parts used to repair older Apple computers. Give us a call or drop in to view our range of used Apple Mac computers.
