Code sample

Code

A simple hello world that does an "import ssl" is sufficient to reproduce along with a "flet build macos" and try to run app.
Should keep in mind here I am talking about the final build macos app, and not just running flet in pycharm or vscode, as that of course would work....

To reproduce

A simple hello world with "import ssl" or import aiohttp or httpx which will call import ssl for you under the hood.
flet build macos
and run the app in build/macos folder.

Expected behavior

The app should run fine, end users should not be expected to install python or openssl in order to run app. On windows builds the .dll files are included in same directory as the app itself, on macos the .dylib could be included. At this point I am thinking VMs should be created that are fresh for MacOS/windows with no python or anything development related installed and see if a simple flet program with 'hello world" and import ssl are working.

Operating System

macOS

Operating system details

Mac Mini M4

Flet version

Latest devel

Regression

No, it isn't

Suggestions

After app is built you could do something like

mkdir build/macos/<appname>/Contents/Frameworks/Python.framework/Versions/3.12/lib
cp -f /path/to/libssl.3.dylib build/macos/<appname>/Contents/Frameworks/Python.framework/Versions/3.12/lib/
cp -f /path/to/libcrypto.3.dylib build/macos/<appname>/Contents/Frameworks/Python.framework/Versions/3.12/lib/

or maybe _ssl.cpython-312-darwin.so could be built statically to include those 2 .dylib files somehow...

Additional details

There are more dylib files that may be needed for other things as well:

Have you signed and notarized the bundle?

[FeodorFitsner]

I'm going to perform a full test of macOS packaging. Two things I suspect: 1) the app needs some entitlements: https://forums.developer.apple.com/forums/thread/716918 (also, flet build creates non-sandboxed app) and 2) it could be a problem with signing 3rd-party python packages (like pydantic) unpacked during the first run.

[dsx1986]

Have you signed and notarized the bundle?

Yes, I signed through xcode build/archive using mac distribution certificate and profile, and it passed app store connect upload. The error happened when I test in through TestFlight

[FeodorFitsner]

Good, will be investigating the issue. Packaging has #1 priority for us.

[FeodorFitsner]

@syleishere SSL issue has been fixed. macOS package now includes libcrypto.dylib and libssl.dylib. import ssl in Python worked for me. Re-build the app. I'm closing this issue as fixed.

@dsx1986 For "library load disallowed by system policy" error I've opened another issue: #4543

How do we get latest fix? Did you release new version?

[FeodorFitsner]

I've updated iOS distro here: https://github.com/flet-dev/python-build/releases/tag/v3.12
It gets downloaded every time you flet build. Delete build directory in your project and re-build the app.

[syleishere]

All good.
