ProSelect 64-bit and OSX 32-bit Warning

Updated Nov 13,2018

With a late update to OSX 10.13 (High Sierra) and now with OSX 10.14 (Mojave), Apple now provides a warning that some applications may not be "fully optimized" for OSX in the future. Since the current 2018r1 and prior releases of ProSelect are 32-bit applications, they will cause this warning to be displayed. Don't be alarmed!

When MacOS High Sierra (the current OSX release) was announced at WWDC in June 2017, Apple said that it would be the last version of macOS to run 32-bit apps "without compromise". They have not changed this position as can be seen in the current explanation of their recent warning. In the article, Apple also says that "final transition dates have not yet been established."

From past experience with Apple, we take this to mean that any new operating system features will not be supported in the 32-bit APIs going forward and any new or existing bugs in those APIs may not be fixed.

This means that all your 32-bit applications will not suddenly stop working if you choose to install Mac OSX 10.14. While we have not done extensive testing of ProSelect 2018r1 on Mojave, we know that a number of our users have upgraded to Mojave and have not reported any problems so far (see section below).

ProSelect 2019r1 (64-bit for OSX) is coming!

While ProSelect is currently a 32-bit application, some of its Helper apps are already 64-bit. ProSelect also already accesses memory beyond the 4MB (the current directly accessible limitation for 32-bit applications) for its performance memory caches.

We have been testing a 64-bit version of ProSelect on OSX since July and it works great. We plan to release a public beta of ProSelect 2019r1 as a 64-bit application in November with final release planned for the end of this year. The Windows version of ProSelect 2019r1 will be released as a 32bit bit app for now.

Life on the bleeding edge

As technology continues to change and evolve, software applications will continue to evolve as well. However, we always recommend to our customers: if you rely on certain software in your business, don't be the first to download each new major operating system release when your current system is working reliably. In fact, there may be no need to change at all unless the new release includes compelling new features that you will immediately benefit from or you need to upgrade your hardware.

Either way, it's a good idea to wait at least for the first minor update has come out (eg OSX 10.14.1) before upgrading so other users can find any issues and Apple and Microsoft can get them resolved.

If you have any other questions about ProSelect 64-bit, please feel free to contact us through our Support Ticket system.
