I have a strange problem, some apps that I download do not launch. There are 2 scenarios

  1. The application starts but keeps bouncing, once I click the bouncing icon in the tray it disappears. The process also closes in activity monitor

  2. The application fails to start, how ever many times I launch it, it refuses. The process does not even show up in activity monitor

What I have done so far to resolve:

  • Repaired permissions
  • Clear all cache/temp using CleanMyMac
  • Used DiskWarrior via OS and not during boot

Something interesting in the system log in Console.app? –  Daniel Beck May 24 '12 at 6:52
Try to remove the com.apple.quarantine extended attribute from the applications in Terminal. Maybe there's a problem with the dialog usually asking for permission to run downloaded software. –  Daniel Beck May 24 '12 at 6:53
I got this in the log: ([0x0-0x9f19f1].com.fiplab.facetabpro[12505]): posix_spawn("/Applications/MenuTab Pro for Facebook.app/Contents/MacOS/MenuTab Pro for Facebook", ...): Permission denied May 24 00:05:03 kps-MacBook-Pro com.apple.launchd.peruser.501[141] ([0x0-0x9f19f1].com.fiplab.facetabpro[12505]): Exited with code: 1 –  KPS May 24 '12 at 7:05
these are the permissions: drwxr-xr-x 3 kps staff 102 Dec 31 15:00 MenuTab Pro for Facebook.app –  KPS May 24 '12 at 7:08
Please post ls -le@ output. –  Daniel Beck May 24 '12 at 7:10

The actual executable, /Applications/MenuTab Pro for Facebook.app/Contents/MacOS/MenuTab Pro for Facebook doesn't have the execute permission. Resolve by running:

sudo chmod +x '/Applications/MenuTab Pro for Facebook.app/Contents/MacOS/MenuTab Pro for Facebook'

Additionally, parts of the application have the com.apple.quarantine extended attribute set, as determined by ls -l@. Remove as described in this other topic. This shouldn't be an issue, but you never know. It sometimes prevents applications from being started from the command line.

Usually when that happens could be one of this two reasons:

  • The application doesn't support Intel Mac (only power pc)

  • The application doesn't support Lion

Have you checked if the applications you are trying to run are for Intel Mac and Lion?

A Google search reveals the app is in the Mac App Store... –  Daniel Beck May 24 '12 at 7:38
So the app is supported on Lion and this is not the only app that I am having issues with, it just so happens it was available for me to post info about. –  KPS May 24 '12 at 20:42
When I cd into the .app this is the attributes: Lalys-MacBook-Pro:contents laly$ ls -le@ total 16 drwxr-xr-x 5 laly staff 170 Dec 31 15:00 Frameworks -rw-r--r--@ 1 laly staff 1840 Dec 31 15:00 Info.plist com.apple.quarantine 15 drwxr-xr-x 3 laly staff 102 Dec 31 15:00 Library drwxr-xr-x 3 laly staff 102 Dec 31 15:00 MacOS -rw-r--r--@ 1 laly staff 8 Dec 31 15:00 PkgInfo com.apple.quarantine 15 drwxr-xr-x 67 laly staff 2278 Dec 31 15:00 Resources drwxr-xr-x 3 laly staff 102 Dec 31 15:00 _CodeSignature –  KPS May 25 '12 at 3:56

For the records: the application The Unarchiver may cause this issue.

Version 3.2: * Added a workaround for a sandbox bug in Mac OS X that was causing extracted apps to not launch properly.
