I purchased a Mac computer from DN Printer solutions and it worked flawlessly until I did an update from Apple. Apparently there was an issue with the update that was no fault of DN Printers however I reached out to see if they could help and they went above and beyond to help me correct the update issue. They went out of their way to ensure that the issue was resolved. They immediately shipped out a flash drive with the operating system loaded on it and problem solved! You can certainly buy with confidence from these guys…they make sure you’re happy even after the sale. They’ve earned a customer for life! - Gregory G.
