How can I update MiKTeX executables on Mac/Linux?

New MiKTeX binaries for Mac and Linux will be made available from time to time (say, 6 times a year).

Mac

If a new disk image (.dmg) is available, you can use it to reinstall the executables. Your MiKTeX configuration will not be affected.

Linux

You get new MiKTeX executables via your package management system. Either automatically, or manually:

sudo apt-get update
sudo apt-get upgrade miktex
