I need experienced writers who understand the Mac OS system and familiar with the technical language. Please attach previous writing work with relevant computer articles with the proposal. It is strict to submit the job on time, good quality and without any plagiarism. If time delayed, poor quality(like combining content from other articles, poor logical content et.) and plagiarism happened, the working relationship will be canceled after pointing out immediately. We will provide a wide-range topic of articles consistently. So I hope to build a long-term relationship with professional writers.
