What it is:

ArcGIS Pro is ESRI’s newest, 64-bit, addition to the ArcGIS collection of desktop software.  ArcGIS Pro offers a contemporary design with greater 3D visualization and enhanced integration with ArcGIS Online. Those new to GIS desktop software will likely want to start their GIS learning with ArcGIS Pro. Current ArcGIS desktop users (ArcMap users) should think about transitioning to ArcGIS Pro as time and needs dictate. At this time ESRI plans to continue parallel development of both ArcGIS Pro and ArcMap for the next few years. Getting started information about ArcGIS Pro is available at http://www.esri.com/software/arcgis-pro

Things to know:

• ArcGIS Pro requires robust computer capacity.  For system recommendations and to check your computer’s ability to run ArcGIS Pro see  http://pro.arcgis.com/en/pro-app/get-started/arcgis-pro-system-requirements.htm
• Note that Microsoft .NET 4.6.1 or later must be installed prior to installing ArcGIS Pro 2.
• Note that Windows 8 is not supported by ArcGIS Pro 2.
• Both ArcGIS Pro and the ArcGIS Desktop (ArcMap) can be installed on the same computer.
• Projects created in ArcMap (.mxd) can be imported into ArcGIS Pro but not vice versa.
• The current authorization process for ArcGIS Pro is via an ArcGIS Online for Johns Hopkins account.

Running ArcGIS Pro on a Mac:

Both ArcMap and ArcGIS Pro are programs designed to be run on the Windows Desktop operating system (OS). If you have a mac, you must first use Bootcamp to partition your drive, install Windows Desktop OS and then install ArcGIS Pro on this Windows desktop partition. 

The minimum hardware requirements for running ArcGIS Pro on a Mac are slightly higher than for running ArcGIS Pro strictly on a native Windows computer. Refer to Esri's documentation here for more details. 

Important message for Mac users:

Prior to ArcGIS Pro 2.3, it was possible to run ArcGIS Pro on a Windows virtual machine (VM) on MacOS using two common deployments: Parallels or VMware Fusion. However, at ArcGIS Pro 2.3, the minimum version requirements for OpenGL and DirectX increased beyond what is supported by the underlying MacOS.

If you are maintaining one of these deployments using an earlier version of ArcGIS Pro, it will continue to work as long as you do not install ArcGIS Pro 2.3 or later. In this case, you should reject notifications that may appear when newer versions of ArcGIS Pro become available.

If you are installing ArcGIS Pro for the first time on your mac, click here to download version 2.2. You may follow the instructions below, but skip Step 2 and use version 2.2 instead. 

Instructions:

STEP 1 Enable Authorization

1. If you haven't already, log into the ArcGIS Online platform for Johns Hopkins using your JHED ID and password. This will create an ArcGIS Online account for you, and authorize you to use ArcGIS Pro.
   Note: Once authorized, you'll see ArcGIS Pro listed as one of the "Licenses Products" in your ArcGIS Online Profile.

STEP 2 Download

Download the desired version of ArcGIS Pro. 

If you are installing on a Mac, see the note above concerning Mac users.
