Valgrind for macOS Mojave 10.14.2? Any alternatives?

Ok, so I saw that someone asked this question over 4 months ago. But it has been a decent time since Mojave has been out. Does anyone know how to get it working or possibly any alternatives so that I can check my programs for memory leaks. I am a student, so cost does matter but this is a requirement for several of my classes. I would prefer not to have to use a virtual machine considering they never run well on Macs. Any suggestions would be great. Thanks.

You have few options here.

  1. You can use XCode for development and run the code in Profile mode.

  2. You can start Instruments and attach to process

  3. You can run the code and use leaks to determine the leak size
