To use ArcGIS Pro on a Mac, a contemporary Mac ( MacBook Pro, iMac, or Mac Pro) with a quad-core Intel processor, 256 GB storage, and 8 GB RAM or more is required. Earlier versions of Parallels are not recommended with ArcGIS Pro. Running ArcGIS Pro 2.3 and later on a Windows virtual machine (VM) on MacOS requires Parallels version 15 or later.
