Gatekeeper on macOS helps protect users from downloading and installing malicious software by checking for a Developer ID certificate from apps distributed outside the Mac App Store. Make sure to sign any apps, plug-ins, or installer packages that you distribute to let Gatekeeper know they’re safe to install. And now, you can give users even more confidence in your apps running on macOS Mojave by submitting them to Apple to be notarized.
Prepare for Distribution
A Developer ID certificate lets Gatekeeper verify that you’re a trusted developer when a user opens your app, plug-in, or installer package downloaded from outside the Mac App Store. Software signed with a Developer ID certificate can also take advantage of advanced capabilities such as CloudKit and Apple Push Notifications.
Mar 31, 2020 If you enter python –version, you will get a different version number i.e., the Python 2 version. At this point, we don’t recommend removing Python 2 from macOS since there are still a few kinks that Python 3 and pip have on the Mac platform.
Generate your Developer ID certificate.
You can generate your Developer ID certificate in Xcode or in the Certificates, Identifiers & Profiles section of your developer account. Please note that you must be the Account Holder of your development team in the Apple Developer Program.
Sign and test your app.
Enable the hardened runtime capability and declare entitlements for the functions your app requires in Xcode. Archive your app and test the end-user experience of launching your Developer ID-signed app using a Gatekeeper-enabled Mac.
Xcode
Mac Python App
To build your apps for macOS and submit them to be notarized by Apple, use Xcode 10 or later, available from the Mac App Store.
Get Your Software Notarized
Give users even more confidence in your software by submitting it to Apple to be notarized. The service automatically scans your Developer ID-signed software and performs security checks. When it’s ready to export for distribution, a ticket is attached to your software to let Gatekeeper know it’s been notarized.
For step-by-step details on uploading your Mac software to be notarized, read Notarizing Your App Before Distribution and the Xcode Help Guide.
Submitting with Xcode
Unpublished Software. It’s easy to get unpublished software notarized with the Export process or xcodebuild. Custom build workflows are supported by the xcrun altool command line tool for uploading, and you can use xcrun stapler to attach the ticket to the package.
Published Software. To submit software you’ve already published, upload it using the xcrun altool command line tool. Several file types are supported, including .zip, .pkg, and .dmg, so you can upload the same package you already distribute to users.
Viewing Upload Logs
In addition to checking for malicious software, the notary service catches common code signing problems that can prevent your software from installing properly. If notarization fails for your upload, check the status log for details.
Upcoming Requirements
When users on macOS Mojave 10.14 or later first open a notarized app, installer package, or disk image, they’ll see a more streamlined Gatekeeper dialog and have confidence that it is not known malware.
Mac apps, installer packages, and kernel extensions that are signed with Developer ID must also be notarized by Apple in order to run by default on macOS Catalina.
Update Python Mac Os
I wondered if Apple will make Python readily available for Sierra. I just upgraded but, really wish I had not as I have no means to return to El Capitan for gone are the days when we could all rule our own machines, and enjoy doing scripting progrms for our own entertainment such as Hypercard. Those days were better that today when shareware was exciting, and computing a lot more fun. I tried to find out from Apple about any programs I could enjoy in the privacy of my own machine without being expected to join in a world community and wishing to know all about marketing an app for the phone. I am a simple type who likes to make games and ideas for only me, but without knowing 'C' I am stuffed. I may need to buy another computer to gain El Capitain once again or hang around in the Modern world with sierra 'slug', and continue to find my photo disk takes 3 trys to get it to registar, and wonder if I to will be allowed to learn Python or for that use my computer for anything at all without inviting in the Microsoft world of Bill Gates who we all know always uses a third party for nobodys like me, and like most of the USA want a big chunk of everyones life. The money worshipping misers with their mental problem of hoarding are happy. It seems to me that my compuer is nothing really more than a music station and extention of a camera neither of which I am the slightest bit interested in.
