Important Note for macOS® Users

The latest version of macOS, 10.15 Catalina, removes support for 32-bit applications. This means that current versions of MPLAB X IDE (up to version 5.40) will not run on this operating system without a patch. All current versions of MPLAB XC compilers are now compatible with this latest version of macOS.

Download macOS Patch

All MPLAB tools are based on 64-bit applications beginning with the following versions:

  • MPLAB X IDE v5.40
  • MPLAB XC8 v2.20
  • MPLAB XC16 v1.50
  • MPLAB XC32 v2.40
