I was playing around with a python script that downloads and changes the wallpaper, and suddenly the wallpaper went black and won’t change even through the preferences menu. The dock also stopped working and I am no longer able to switch apps using cmd + tab.
I tried restarting the computer, resetting the PRAM, deleting both the com.apple.finder.plist and the com.apple.desktop.plist files, and running a defaults write com.apple.finder CreateDesktop true; killall Finder command. If I run a killall Dock it says they there are no Dock processes running.
The python script I was playing with was just running a simple osascript:
/usr/bin/osascript<<END
tell application "Finder"
set desktop picture to POSIX file "%s"
end tell
Nothing worked. Any ideas on how I could fix this problem? Im on Monterey.
I found a solution. It was hidden in a comment on another similarly related stack overflow question here.
As described by one of the comments, the problem happened after trying to set a malformed image file as my background. I followed the suggested step to delete my ~/Library/Application Support/Dock directory, which solved the problem instantly.

Recently I developed an application in Xcode using Swift that starts up the Terminal like this and:
open -a /Application/Utilities/Terminal.app /project/run_stack.sh
After exporting the Application and trying to run it I get this message if my Terminal is running already or I have previously started the same command from the same app (the command is executed through a menu item).
ru_stack.sh can’t be opened because Sandbox is not allowed to open documents in Terminal.
Anyone know why this happens ? If I run it on my Mac it works fine and each time a new terminal starts on the call but when I tried the application on my friend's Mac we get that error in the described cases.
I was having the same problem. I ended up setting iTerm2 as the "Open With" application for .sh files and that fixed my issue. https://iterm2.com/
Sometimes when I update anything from App store and my mackbook pro restarts , when I log in back I found all applications status saved includes my terminal commands history+output darkened in grey color.
My problem , When I do manual restart or quitting the Terminal app , I re-open it with nothing at all !
How Can I get all my commands history+output darkened as a grey text when I manually quit the Terminal app ?
Thanks

I'm using OSX's launchctrl functionality to automatically relaunch an app after it crashes.
Unfortunately, when the app relaunches, it launches together with an action window that reads:
"The last time you opened MyAppName, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?"
I tried to suppress it by calling NSQuitAlwaysKeepWindows
defaults write -app /Path/to/app/MyAppName.app NSQuitAlwaysKeepsWindows -bool false
But this only works some of the time - I'd say that the popup window launches 50% of the time.
This window requires action and blocks the app from jumping into a full screen mode.
I'm on OSX 10.8.4
Thanks for any ideas ...

Open the folder "~/Library/Saved Application State" and look for a file like "some.url.MyAppName.savedState".
Deleting this file might probably solve the problem, at least it worked for me.
I was able to fix mine by deleting the Envelope Index file(All the files with the name "Envelope Index") under /Library/Mail/V2/MailData folder.
Then restart the mac.
I am working on a cocoa application. I see a strange behaviour on Mac OS 10.6.8..!
My Cocoa application has an Automator action inside it. I want it to be listed in Automator as soon as I install it.
The conditions are as follows:
1. After installation, user should not go to the installed path.
2. User should not launch the application.
I mean, I am seeing this bug only for above mentioned situations. If I go to the installed folder, or launch the application, the automator app gets listed.
I didn't see this defect on Mac OS 10.7.5 or Mac OS 10.8.2..
Also I tried touch command via terminal just in case thinking that if any kind of Access updating is required and all. But that wasn't the case.
Any suggestions? Can I run any kind or Shell/Applescript while installing [After installation of the application] so that I can list the automator action in automator?
Any advice or help would be great!!
You can have a .txt file with the below script and then you have to add postflight script when taking .pkg file in Package Maker.
open "/Applications/yourAppName.app"
Try this Terminal command.
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister .../Whatever.app
You shouldn't hard-code the path, though, as users sometimes stick apps in weird locations (citation: I do it :).
I am trying to make a kiosk, I actually wanted to lauch my app before the Finder got launched, I wrote the following command:
defaults write com.apple.loginwindow Finder ~/Desktop/myapp.app
and it worked, but now I have a huge issue, my Finder wont get launched at all, instead everytime my application is launched when I press the Finder, Before I was getting erroR -10810 but I fixed that. I tried reversing the process but it isnt working. My mac is useless and I cant get to my files.
Target is to reverse the process and make my finder works again as normal
