The technical specifications for Adobe InDesign CC 2015 required a robust system to function at its best. On Windows, it called for an Intel Pentium 4 or AMD Athlon 64 processor, while Mac users needed a multicore Intel processor. The software thrived on at least 8GB of RAM and required a high-resolution display to manage its dense toolsets and panels. Despite being several years old, many production environments still maintain workstations with this version due to its renowned stability and its ability to open legacy files without the reflow issues sometimes seen in much newer versions.
