Apple Silicon Upgrade Available Now

Apple provided a translation/emulation layer called Rosetta 2 to allow Intel-based Mac applications (x86_64) to run on Apple Silicon Macs (M1, M2, M3, M4, etc.).  As a result, there was no need to build an Apple Silicon based deployment of NM Collector Software.

​

What Rosetta 2 does

​

Rosetta 2 dynamically translates Intel machine code into ARM64 code that Apple Silicon processors can execute.  This allowed most existing Intel Mac applications to continue working during Apple’s transition away from Intel CPUs beginning in 2020.

​

What has changed?

​

The message in the image above recently began showing up for users of Apple Silicon Macs running the Intel version.  It means the Rosetta translator will no longer be available in future Mac operating systems: Apple has said Rosetta will be largely removed in macOS 28, expected in fall 2027.  Thus the need to build an Apple Silicon version of NM Collector Software.

​

When will it be available?

​

It is available now.  Download Apple Silicon (M1 and later) on the Downloads page.

​

Which version do I need?

​

Choose Apple menu > About This Mac.  If it shows “Chip: Apple M…”, your Mac has Apple Silicon: download Apple Silicon (M1 and later).  If it shows “Processor: Intel”, download Intel Mac.

​

The Intel version is for Intel Macs.  On an Apple Silicon Mac it only runs through Rosetta, which is why the message above appears.

​

Switching from the Intel version

​

Install the Apple Silicon version in place of the Intel one, the same way you installed it before; the Mac installation instructions cover the steps.  Switching does not change your collections, items or pictures: they are kept in your Mac’s user Library folder, not inside the application, so the new version opens the same data.
