I needed a MS Office licence for my Mac. When I first saw the prices on SoftwareKeep, I had doubt if those were authentic MS software. After reading the reviews, I felt comfortable enough to give it a try. I purchased a MS Office 2019 Home and Student for Mac. They upgraded me to Home and Business for Mac with no additional charge. I received the licence key in the email that came with a clear step by step installation instruction. Due to my limited computer knowledge, I needed additional help while installing. Their chat room technical support staff were very patient and super helpful. The licence is authentic. It shows up in my MS account. All applications are working perfectly. A big thank you to SoftwareKeep!
