With the introduction of macOS High Sierra Apple introduced the new APFS file system. Once the list has been created you can thenĬontact the developers of the apps to see if they provide 64bit updates. Use this app to discover which apps you haveĪre 32bit. Some updates may be free, some may be paid. Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps, If you are considering upgrading to Catalina be warned that it does not support 32bit apps. How much RAM does your mac have installed, Mojave and Catalina benefit from havingĨGBs of RAM minimum, the others are OK on 4GBs minimum. It will probably be able to upgrade to Big Sur when it is released in the near future. Next: Method #3 – The macOS command line, short and sweet.Your mac being a 2015 model can upgrade to any macOS from Sierra, High Sierra, Mojave and Catalina, Moving on, for simple, beginning C++ learning, there is a quick and easy solution. This solution may be a challenge for many beginning C++ students, but it would work very well for very technical students or programmers already familiar with development in Linux and who are transitioning to a Mac. You’ll be able to debug your code, and it can get as complex as you need it to. But you’ll have your work cut out for you learning your VM setup, Linux install and maintenance, IDE of choice install and use. Once you have, say, Linux Fedora installed as a guest VM on your Mac, the sky’s the limit with C++.

Make sure you specify the full developer options during install. Plus, Fedora comes with an install of the very capable Eclipse IDE (more on that below). We recommend Fedora or CentOS because they’re free and come with the required GNU compilers (g++) and debugger (gdb). Once you have your VM system running, you can then download the ISO image of the Linux distribution of your choice and install it as a guest OS.

Fedora as a guest OS, a virtual machine in macOS.
