Altstore: Mail plugin doesn't support macOS 11.0 Beta
The Mail app which comes with latest macOS 11.0 Beta (20A4299v) doesn't support AltPlugin.mainbundle. This makes the app unusable.
Steps to reproduce the behavior:
1.Install the Mail plugin on AltServer app.
2.Open(restart if already open) Mail app & go to the Preferences
3.Click "Manage Plug-ins..."
4.Check "AltPlugin.mailbundle"
5.Click "Apply and Restart Mail"
- Observe
- OS: macOS 11.0 Beta (20A4299v)
- Version: Big Sur

afaik this should be an easy fix, if you know where the mail plugin is installed ( I don't) you can probably edit the package contents and change the mail version to 13

Add this to "/Library/Mail/Bundles/AltPlugin.mailbundle/Contents/info.plist" after the last </array> tag and before the last </dict> tag:
(Sorry for the download, was the best way to keep the formatting)
Re-enable the plugin in Mail and restart Mail and you should be good to go until we get an official update.

@ygzok May I ask why the issue has been closed if the patch hasn't been merged into the sourcecode yet? I mean, even if I can apply it manually, this still needs to be fixed… Or do you use an off-site todo/issue system?
