Mac OS X 10.6
I created a very simple app, which is only a wrapper of a shell script (so that I can select this script in application selectors, like startup apps). I try to launch it and yesterday it worked, but today I changed the executable script's content and name (with something that perfeclty works in a shell script launched in the Terminal) and it will only display a Finder-iconed dialog saying
Cannot open the application because it is not supported on this kind of Mac.
I restored the previous script (content/name) but I still get the error! Same when re-bundling the app from scratch, or completely changing the bundle identifier…
If I try to open it in the
Terminal using open My.app, I get
The application cannot be opened because it has an incorrect executable format.
But when I executes directly the Contents/MacOS/Script, it allways works (iwth both contents). Also, it is displayed with correct icon and meta-information in the Finder (so I guess the Info.plist is understood).
The app's file tree is:
Contents/
Info.plist
MacOS/
Script (executable bit set, works when launched directly)
PkgInfo
Resources/
AppIcon.icns
Here is the Info.plist content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>CFBundleExecutable</key>
<string>Script</string>
<key>CFBundleIconFile</key>
<string>AppIcon</string>
<key>CFBundleIdentifier</key>
<string>asdf.ScriptApp</string>
<key>CFBundleInfoDictionaryVersion</key>
<string>6.0</string>
<key>CFBundleName</key>
<string>My script</string>
<key>CFBundlePackageType</key>
<string>APPL</string>
<key>CFBundleShortVersionString</key>
<string>1.0</string>
<key>CFBundleSignature</key>
<string>????</string>
<key>CFBundleVersion</key>
<string>1</string>
<key>LSMinimumSystemVersion</key>
<string>10.4</string>
</dict>
</plist>
And the PkgInfo file only contains APPL????. I tested the Script with a simple echo "ok" and echo "ok" >/tmp/test (plus #!/bin/sh header).
So my questions are:
Is there some kind of validity caching for applications ? based on what ? how do I flush it ?
Where does this message come from ? I tried to google it but all I get is a page talking about 32/64 bits Java…
