macOS says I need to install Rosetta, but it isn't true

[marco-brandizi]

I've downloaded DavMail-MacOSX-6.3.0-3627.app.zip and tried to use it on an M4. When I click on DavMail.app, macOS says I need to install Rosetta. However, that isn't true, since the package contains a shell script, which runs a Java app.

In fact, when I run DavMail.app/Contents/MacOS/davmail from the command line, DavMail starts without issues, the same when I run it from the bare .zip davmail-6.3.0-3627.zip.

While it's not a big issue, I'd like to be able to run it from a macOS package format, since this makes adding it to the login items easier. I guess it's about adding a download for Silicon Macs, while the current one is for old Intel devices. Would this be possible? I could also repackage it on my own, using the macOS Automator, yet having a public download would be simpler for anyone who needs it.

Thanks.

But it seems you also need to change the bundle ID in the Info.plist for macOS to recognize the fix on systems which have already triggered the Rosetta message.

Found this possible workaround:

Add in Info.plist:

<key>LSArchitecturePriority</key>
<array>
    <string>arm64</string>
</array>

LOL, that's basically the same link that I posted above. But, again, it will only work for @marco-brandizi if they also change the bundle ID in the Info.plist.

Many thanks, this worked for me:

    <key>LSArchitecturePriority</key>
    <array>
      <string>arm64</string>
    </array>
    <key>CFBundleIdentifier</key>
    <string>DavMail4ARM64</string>

Hope an ARM download will be published.

@esabol my bad: I had the page open to investigate, found the possible workaround and posted it a few hours later without refresh... didn't see you already answered.
