In 2006 it all started in Zaandam, The Netherlands when Bas Tel started a business in Apple hardware, service and a personal touch were our USP's. 

In 2008 we moved to Wormerveer, The Netherlands. At this location it became a more serious business. 

In 2012 we started our Dutch webshop onlinemacwinkel.nl, RAM and SSD upgrades were and still are our specialty.

In 2013 we moved back to Zaandam to a bigger office at the Penningweg 82, this is still our current location.

In 2017 a second webshop focused on the German market started, 4mac.de

In 2019 4mac.com started to serve the whole European market.
