Bluebeam Revu is not available for Mac but there are plenty of alternatives that runs on macOS with similar functionality. The best Mac alternative is Adobe Acrobat DC. It's not free, so if you're looking for a free alternative, you could try Master PDF Editor or KDAN PDF. If that doesn't suit you, our users have ranked more than 50 alternatives to Bluebeam Revu and 15 are available for Mac so hopefully you can find a suitable replacement. Other interesting Mac alternatives to Bluebeam Revu are Qoppa PDF Studio, Foxit PDF Editor, PDF Expert and Wondershare PDFelement.
Layout is like adobe but has all the bluebeam functions, unfortunately the free version will leave a watermark on the doc if you try to save any edited version. $50 for a single license is too steep maybe $5-12 not $50
