The status of 32-bit and 64-bit macOS apps

In the Mac world, 32-bit apps have been disappearing more and more as time goes on. This year already we’ve seen significant steps toward 64-bit.

In January 2018 Apple stopped accepting 32-bit app submissions to the Mac App Store.

In February 2018, starting with macOS 10.13.4, Apple added a warning that displays the first time you launch a 32-bit app.

In June 2018 Apple stopped accepting updates to 32-bit apps in the Mac App Store. All new apps and app updates must now be 64-bit.

At WWDC 2018 Apple announced that macOS 10.14 will be the final version that support 32-bit apps. Although they did not announce a release date, based on the timing from the past few years macOS 10.14 will probably be released around the end of September 2018.

Avoiding False-Positive Virus Detection in Windows Apps

Viruses continue to be a big problem on Windows. As a result, anti-virus software can be a bit over-zealous about detecting what it believes to be apps that have viruses embedded within them. We have had reports over the years that apps made with Xojo are sometimes falsely identified as being infected with a virus. This sometimes occurs because the 32-bit Xojo compiler puts executable code in a location where the anti-virus software doesn’t expect to find it. We’ve seen this occur even when users are debugging apps from the IDE. Fortunately in that case, there’s a fairly easy solution.
