Hi John,
The software features between the Mac and Linux version are identifical but there some differences, like on the Mac version, there are alot more Quicktime codecs supported as on the Linux platform it is very limited so if you have ProRes Quicktime clips, they will need to be converted to DPX first. If you plan to get the Resolve Control Surface grading panel as part of your upgrade, you’ll get the Resolve Mac version which you can use that as an assistant station to do these conversions. You can also use it to conform your project, injest video, render session…etc but you’ll need a shared storage for efficiencies and a database server so that both the Resolve Mac and Linux can share the projects.
The other key differences is in the GPU processing as the Resolve Mac is limited to 3GPUs whereas on the Linux platform you can scale all the way to 16GPUs, depending on the kind of work you are doing.
