IDL has the following system requirements:
- Operating systems:
- Disk space: Approximately 4 GB for installation
- Memory (RAM): Minimum of 8 GB
- Number of processing cores: Minimum of 2, recommended 4 or more
An X-Windows manager is required for macOS. IDL was tested using XQuartz 2.8.5
A Rosetta 2 emulator is required for Mac M1.
Most image display and processing capabilities in IDL have been designed to work with minimal amounts of system RAM. Having a lot of RAM can help to avoid occasional memory allocation problems, especially with large datasets. Tests have shown that 8 GB of RAM is adequate for most tasks run using the latest versions of IDL. However, if you anticipate working with very large datasets, or if you are building custom applications with ENVI+IDL code, then you may consider adding more RAM to your system.
