macOS 64-Bit Apps

Posted 9th August 2019

The next version of macOS (10.15), due later this year, will completely drop support for apps built in 32-bit mode. For a while now (since 10.13.4) macOS has been issuing warnings when running 32-bit apps as a reminder, and you may have seen these if you use my software. So it’s time for some updates!

Two apps, Ephemeral and psxdmh are already 64-bit. But three others aren’t:

Over the coming weeks I’ll be releasing updates to these apps to convert them to be 64-bit. I’ve started work on converting all of them and it’s been progressing well (far less painful than I had imagined).

Stay tuned for updates very soon!
