A longstanding issue is that DropDMG&rsquo;s <a href=\"https:\/\/c-command.com\/dropdmg\/help\/command-line-tool\">command-line tool<\/a> uses AppleScript to communicate with the main app, but if you&rsquo;re running <code>dropdmg<\/code> from a shell script (e.g. an Xcode build script), macOS doesn&rsquo;t know to prompt you to <a href=\"https:\/\/c-command.com\/dropdmg\/help\/granting-automation-acc\">grant Automation access<\/a>. (There is no way to grant such access manually because the checkbox doesn&rsquo;t show up in System Settings until after the prompt.) A workaround has been to run an AppleScript from Xcode (or whatever the controlling app is) that does something innocuous like ask DropDMG to <code>get version<\/code>. That will trigger the Automation access prompt. This no longer seems to work with macOS 15, so we now recommend using the <code>beep<\/code> command instead.<\/p><\/li>\n\n<li><p>The most common reason that a <a href=\"https:\/\/c-command.com\/dropdmg\/help\/signing\">code signing<\/a> certificate would not be shown in DropDMG is if your private key is missing from the keychain. I don&rsquo;t know why these seem to get lost or not migrate properly. Private keys cannot be redownloaded from Apple, so you either need to generate a new one or export it from the keychain on your old Mac.<\/p><\/li>\n\n<li><p>With SpamSieve, it seems like <em>most<\/em> of the erroneous Gatekeeper errors saying that the app was damaged (thus necessitating the <a href=\"https:\/\/c-command.com\/download-fixer\/\">Download Fixer<\/a> tool) were triggered by a hardened runtime entitlement (<code>com.apple.security.cs.disable-library-validation<\/code>), which neither app actually needs these days. I removed the entitlement from SpamSieve a few versions ago, and it&rsquo;s now gone from DropDMG, too, so hopefully these errors will be much less frequent now.<\/p><\/li>\n\n<li><p>I recently learned about the <a href=\"https:\/\/github.com\/boredzo\/impluse-hfs\">impluse engine<\/a> open-source project, which can convert old HFS volumes (which macOS no longer supports) to HFS+.<\/p><\/li>\n\n<li><p>The Mac App Store version of DropDMG is currently stuck in App Review, after being rejected because &ldquo;Your app updates itself outside of the Mac App Store&rdquo; (which is not the case).<\/p><\/li>\n\n<\/ul>\n\n<p>Previously:<\/p>\n<ul>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2024\/09\/26\/dropdmg-3-6-8\/\">DropDMG 3.6.8<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>DropDMG 3.6.9 is a maintenance update to my app for creating and working with Mac disk image files.
