32 bit or 64 bit

edited December 2017 in Knox

Just checking in case Apple will require 64 bit apps with whatever release comes after High Sierra. I hate to lose this guy.

    Knox contains both 64-bit and 32-bit segments. You can inspect this yourself by typing this into Terminal.app:
    file /Applications/Knox.app/Contents/MacOS/Knox

    Apple has already said that as of January the Mac App Store will only allow 64-bit applications to be submitted, and that the macOS update slated for release in the fall will not support 32-bit applications.


  • So, I guess that my friend Knox will no longer work with the fall release?

  • Rudy, this is what I got from terminal,

  • Rudy, so the long and short of all this is???

    x86_64 means that it has 64-bit support, barring some other OS-level change in that release, it should work fine.


  • THANK YOU, THANK YOU. We shall wait and see. :-) Send me a bill. heheheh
