Sorry for bothering again. I would like to obtain some clarification regarding the problems I am having when my screensaver tries to load images that reside on an external disk.
I have read the dev docs on sandboxing ( https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html ‒ thanks a lot for pointing me to those), and I read everything about Security-Scoped Bookmarks (thanks for that pointer, too). First of all, I am wondering whether trying to use security-scoped bookmarks might really help, because the entitlements of legacyScreenSaver do not include com.apple.security.files.bookmarks.* Here is the complete list of legacyScreenSaver's entitlements: <dict> <key>com.apple.private.xpc.launchd.per-user-lookup</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.cs.disable-library-validation</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.network.server</key> <true/> <key>com.apple.security.temporary-exception.files.absolute-path.read-only</key> <array> <string>/</string> </array> <key>com.apple.security.temporary-exception.mach-lookup.global-name</key> <array> <string>com.apple.CARenderServer</string> <string>com.apple.CoreDisplay.master</string> <string>com.apple.nsurlstorage-cache</string> <string>com.apple.ViewBridgeAuxiliary</string> </array> <key>com.apple.security.temporary-exception.sbpl</key> <array> <string>(allow mach-lookup mach-register)</string> </array> <key>com.apple.security.temporary-exception.yasb</key> <true/> </dict> (Obtained using codesign -dvvv --entitlements :- /System/Library/Frameworks/ScreenSaver.framework/PlugIns/legacyScreenSaver.appex/Contents/MacOS/legacyScreenSaver ) So, at least according to the doc, there is no point in trying to use Security-Scoped Bookmarks. What is your experience? Best regards, Gabriel PS: My screensaver can access files in ~/Pictures just fine. Also, it can access files on an external disk, if the directory is provided during the same run via NSOpenPanel. But not in a later run , when it tries to access those same files (on external disk) with user interaction. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
