Hi, I recently created and installed new code signing certificates/keys on my main Mac. How to easily copy these certificates/keys to my another Mac with the same Apple ID? Earlier Quinn suggested: "The easiest way to do this is use Xcode’s import/export feature. Launch Xcode, choose Xcode > Settings, select Accounts, select the account in question, then choose Export Apple ID and Code Signing Assets from the action (…) menu." And it worked fine in 2020-2021. However import/export options are no longer available in XCode 16 anymore. Please suggest a simple solution.

Hi, I distribute my app for macOS outside AppStore. I implemented Auto Update function which worked perfectly up to Ventura 13.0. And it was broken since Ventura 13.1+ The old version of my app downloads a ZIP arhive with a new version to temporary folder and unpack it to User's Library > Application Support > My AppFolder. The new unpacked version gets attribute com.apple.quarantine and the old app cannot run it. Before Ventura 13.1 the new unpacked app could be run successfully and it closes the old version and replaces the old APP bundle in Applications. And then a copy of new app in a temporary folder is being deleted. In fact, the new APP could work as an agent to perform the update of my app. Both apps (old and new) are signed and notarized by one team (the same signature).

Hi, How to correctly check notarization for my product for DMG and APP bundle? For APP, if I use this command: spctl -a -v 'MyProduct.app' It shows OK for my Mac where I compiled and signed this APP, even if this APP was NOT notarized. And this command correctly detects missing or failed notarization: spctl -a -vvv -t install 'MyProduct.app' For DMG I used this command: spctl -a -t open --context context:primary-signature MyProduct.dmg -v However I'm not sure that all these commands on 100% validate successful/absent/failed notatization.

Hi, I have a problem with replacing altool to notarytool to notarize my app for distribution outside AppStore. Earlier I used this code (-p passes App's password): xcrun altool --notarize-app --primary-bundle-id "MyProductBundleID" -u "myname@gmail.com" -p "wxxx-xxxx-xxxx-xxxx" --file MyProduct.zip I wrote a new script: xcrun notarytool submit MyProduct.zip --keychain-profile "wxxx-xxxx-xxxx-xxxx" --wait Error with unknown "--keychain-profile".

We simulate Gaussian blur as a Box Blur with complex shader (several passes on two axises) using Metal on Mac. I noticed slight fast pulsation of picture brightness when we reach radius more than 16 pixels in a fragment shader (we read 32+ pixels from a source texture to calculate 1 output pixel). We use float4 calculations. This issue appears only on M1 Mac and only after sleep. The problem dissappears after restarting macOS. And no problem on Intel iMac with AMD graphics. These artefacts appear in macOS Monterey 12.4 and also in macOS 13 Ventura Beta 1 on M1 Mac mini. We don't have any problem with other more simple shaders.

Hi, I have a question regarding expired codesign certificate. Will users able to install my old app from a DMG when a codesign certficate gets expired? I sign the app bundle and then sign the DMG package. After reading this official information: https://developer.apple.com/support/certificates/ I don't understand it clearly. Apple declares that installed app continues to work, but "users can no longer launch installer packages for your Mac applications". Does it mean that app from a DMG also cannot be mounted and copied to Applications by users? Quote: "Developer ID Installer Certificate (Mac applications) If your certificate expires, users can no longer launch installer packages for your Mac applications that were signed with this certificate. Previously installed apps will continue to run however new installations won't be possible until you have re-signed your installer package with a valid Developer ID Installer certificate. If your certificate is revoked, users will no longer be able to install applications that have been signed with this certificate."

Hi, I suggest Apple to more frequently reply to software developers. My previous replies didn't get any reply or help from Apple. Also many questions from other developers were not answered. I guess that so large company can pay more attention to their sofware developers. We really need more help and replies from Apple to create good software apps for macOS and iOS.

There is a big mess and lack of information about adapting macOS apps for the notch in new MacBook Pro 14" and 16". I simply want to keep the notch in a normal window size. And hide the notch when user switches the main window to a fullscreen mode. I thought that I should add NSPrefersDisplaySafeAreaCompatibilityMode key to a Info.plist. But now I don't know HOW my app will look with this key. Does NSPrefersDisplaySafeAreaCompatibilityMode key gives the same visual result as "Scale to fit below built-in camera" in Finder for a certain app? Or not? When I watched a video where it was shown how "Scale to fit below built-in camera" works, I'm now in a panic, because this option reduced the app window proportionally increasing black borders on the left, right and top sides. It's the most terrible solution which could be chosen. My app should look correctly with a normal window size. And I need the solution only for a fullscreen mode, keeping the same screen width and reducing only top area. Not reducing the entire window! UPD. I think that we will recommend our customers to contact with Apple regarding the notch problem on their new Macbook Pro in a fullscreen mode. I don't see any good solution on our side. We'll remove NSPrefersDisplaySafeAreaCompatibilityMode key and keep things "as is".

Hi, I think that a visual quality of hardware video encoder (VideoToolBox H.264) in M1 Macs is not great. I compared a software libx264 encoder (Mac) and NVIDIA Geforce (NVENC) on Windows 10 with the same bitrate or constant quality mode producing almost identical file size. I see many visual artefacts on a video encoded with VideoToolBox H.264 (1080p 60 fps) 3300K or CQ56. It's especially noticeable on video with animated photo slideshows and blur effect. Too many artefacts. NVENC and libx264 produce much better visual results with the same file size. I tested in my app and in Handbrake Beta for M1 which supports VideoToolBox H.264 encoding. Apple engineers can contact me for more details.

When I check notarization on Mac Mini with M1 chip: bash-3.2$ spctl -a -t exec -vvv '/Applications/My.app' It shows many useless warnings in output.

I compiled a dynamic library for macOS (open source) When I checked with otool -L abc.dylib it shows that it links several other libraries from /usr/lib/ Is it OK, or Apple may remove these libraries in future versions of macOS? /usr/lib/libz.1.dylib /usr/lib/libiconv.2.dylib /usr/lib/libSystem.B.dylib /usr/lib/libbz2.1.0.dylib /usr/lib/libobjc.A.dylib

Is it possible to check a code signature of another application bundle on Objective C? Our app has Auto Update function. We need to check the downloaded APP bundle from a ZIP to make sure that it's our application (valid signature and our name in the signature) before run it.

I have a misterous problem with checking DMG notarization. It fails: bash-3.2$ spctl -a -t open --context context:primary-signature -v MyApp.dmg MyApp: rejected source=no usable signature However this DMG installs fine on Big Sur 11.2.2, macOS allows to run this app, and checking of notarization for installed app was passed: bash-3.2$ spctl -a -v '/Applications/MyApp.app' /Applications/MyApp.app: accepted source=Notarized Developer ID I checked other downloaded apps (Intel or Universal). Some DMG files pass DMG notarization (for example, Audacity), and some fails (PerfectTablePlan). Why? For my app (Universal) I use the following code to codesign and notarize: codesign --timestamp --options runtime --force --deep -s "Developer ID Application: MYCOMPANY" "My.app" // Creating DMG with EULA license xcrun altool --notarize-app --primary-bundle-id MyApp -u "my@email.com" -p "abc123" --file MyApp.dmg xcrun stapler staple MyApp.dmg

When I notarize two apps the same time I get wrong DMG image for second app. I use a command for App1 and then for App2: xcrun altool --notarize-app --primary-bundle-id app1id -u my@email.com -p xxxxxxx --file App1.dmg xcrun altool --notarize-app --primary-bundle-id app2id -u my@email.com -p xxxxxxx --file App2.dmg Then I get an email with a successful notarization, I call xcrun stapler staple App1.dmg xcrun stapler staple App2.dmg DMG with App1 is correct. Signed and notarized. But after stapling DMG with App2 is wrong - it includes App2 and App1 (!) and DMG has increased file size! Of course, I've sent for a notarization only a single App2 in a DMG. What I'm doing wrong? This problem doesn't appear if I send App2 for notarization AFTER successful notarization of App1 and stapling DMG image. macOS 11.1 Big Sur, Apple DTK.

Is it possible to find deprecated functions without Xcode in runtime? I have a project which doesn't use Xcode to build the code for macOS. It would be great if I could see logs in Terminal when deprecated function is called.
