This process requires a few extra steps. Before you start, make sure to be familiar with B4J-Bridge and MacSigner. MacSigner v2.01+ is required.
1. Download standalone python and remove quarantine flags:
Python 3.11 for arm64 Mac: https://github.com/astral-sh/python...1209-aarch64-apple-darwin-install_only.tar.gz
Unzip it inside the "tempjars" folder. This is the folder where the app is being copied to when running with B4J-Bridge.
Run this command from the terminal (run it from the python folder)
B4X:
xattr -dr com.apple.quarantine .You should now be able to run python:
B4X:
cd bin
./python2. Configure PyBridge to find python:
B4X:
Dim opt As PyOptions = Py.CreateOptions(FindPython) 'In B4XPage_Created
Private Sub FindPython As String
Dim paths As List = B4XCollections.CreateList(Null)
paths.Add(File.Combine(File.DirApp, "../runtime/Contents/Home/bin/python/bin/python")) 'running from inside the app package
paths.Add(File.Combine(File.DirApp, "python/bin/python")) 'running with B4J-Bridge
paths.Add(File.Combine(GetSystemProperty("java.home", ""), "bin/python/bin/python")) 'running by double clicking the app
For Each PythonPath As String In paths
If File.Exists(PythonPath, "") Then
Return PythonPath
End If
Next
Log("Failed to find python")
Return ""
End SubTip: B4J-Bridge names the copied jar AsyncInput1 or 2. Rename it to match your app name and add the jar extension, before you select it with MacSigner.
3. When you are ready to package the app, run MacSigner and after the Linking step, you need to copy the complete python folder into temp/build/bin
Test run.command.
4. Further steps are as usual: package the app (test it), notarize, wait for the process to complete (check the status with the id), once accepted click on the Staple button.
The app package is fully standalone with its own copy of Java and Python runtimes.
