I have an iMac that runs macOS Mojave Version 10.14.6 with the 3 GHz Intel Core i5 Processor, 8 GB 2667 MHz DDR4 Memory and Radeon Pro 560X 4 GB Graphics. I've really enjoyed the way MediaWiki presents articles and resources on the various Wikimedia Foundation projects. So, I'd like to find out if I can run MediaWiki on my computer, prepare resources in the course of my research and upload them to one or more of the projects I currently contribute to when it's appropriate to put them into the Public Domain. Currently, I contribute primarily to Wikiversity but have run into a political problem that I cannot solve so I'd like to try preparing resources from home. Can you help?
