Unlike many here who have their own shop, I'm a contract worker jumping around larger corporate customers configuration & fixing their equipment.

Presently I service three large customers winding down from eight.

My largest is in the process of converting from Mac to HP laptop systems as they require USB-A ports in their systems for security key dongle's and other devices which prohibit the use of USB-A to USB-C conversion dongle's.

I will be starting up a mail-in service for MacBook's & MacBook Pro's beginning in 2018.
