I'm getting an (error code -10813) when trying to set file extensions to open with a certain app in Mountain Lion 10.8.5. Where is the plist file that has those preferences so that I can delete it and hopefully end this problem?

When I right-click on a file on my Mac OS desktop and then in the contextual menu, I move to the "Open with...", the list of potential applications to "open with" has applications listed multiple times, sometimes three or four times, right next to each other!   Why does this happen? How do I fix it? how do I stop it from re-occurring?   See this snapshot of the contextual menu showing the doubling up:     Now I have Mountain Lion on a 13" MacBook Pro, but this problem existed before I upgraded to Mountain Lion.

I'm looking for the file that contains all the Time Machine exclusions entered in its Options dialogue. I know that (some of?) the scheduling related settings are stored in the com.apple.backupd-*.plist files at /System/Library/LaunchDaemons but I haven't been able to find the exclusions.

If I save files to iCloud in apps in Mountain Lion that support such saving, where on my drive can I find these files if I want to run command line utilities on them, edit them in other programs, etc?

I'm trying to run a command at 10 minutes after 2am every weekday only.  In my launchd .plist file, how can I specify this?    I don't want it to run every 2 hours and 10 minutes, just once every weekday at the specified time.

It seems that whenever I create a file with touch the permissions are set to: -rw-r--r--.   Is there some way that I can configure the permissions with touch or does this have to be done after with a different command?

Recieved the error:  'Your screenshot could not be saved. You don't have permission to save files in the location where screenshots are stored.' with OS X Yosemite.  I opened terminal and tried directing the screenshots to save on my desktop:  Brigittes-Air:~ eggsalad$ defaults read com.apple.screencapture location 2017-01-06 03:04:47.765 defaults[17729:1947540]  The domain/default pair of (com.apple.screencapture, location) does not exist  So I tried writing and:  Brigittes-Air:~ eggsalad$ defaults write com.apple.screencapture location ~/Desktop 2017-01-06 03:05:08.652 defaults[17742:1948451] Could not write domain com.apple.screencapture; exiting  I'm not sure where the screenshots are being stored if the location does not exist. Ideas?  EDIT  I ran something else and got a different response, but defaults are still unchanged.   Brigittes-Air:~ eggsalad$ defaults write com.apple.screencapture location/Users/eggsalad/Desktop killall SystemUIServer  2017-01-06 03:22:35.444 defaults[18265:2001767] Unexpected argument SystemUIServer; leaving defaults unchanged.  2nd EDIT  Result of:  ls -l ~/Library/Preferences/com.apple.screencapture.plist  was:   ls: /Users/eggsalad/Library/Preferences/com.apple.screencapture.plist: No such file or directory

I know to secure safety it is now not allowed anymore to open apps that were not downloaded from the mac app store.  But surely there is a workaround for this to open an app that you know is 'good' but just isn't in the app store. Preferably allowing only that app and not allowing all downloaded apps to be opened.    How do I open an app that is not downloaded from the app store in mountain lion?

I somehow have set the default file type association for a file type in Windows 7. It doesn't appear to be possible to delete it from the "Change the file type associated with a file extension" options screen. Is it possible to remove it?

I am looking to change a file association on the Mac using some sort of script. I know that I can do something like that in Windows using the assoc command.  Is there something scriptable on macOS which will do a similar job? I don’t mind whether it’s in Bash (my preference), AppleScript or something in Automator.  I am aware of the dutil command but I want to be able to do it without additional software.

I did a quick, pseudo-system audit this morning and found an unexpected directory hogging up ~10GB of space on my drive. I assume that it's a remnant from a reasonably recent upgrade to XCode 4, but that's more of a guess than anything else.  I'm not an Objective-C/Cocoa developer. XCode is really installed just to support Homebrew. Off the top of my head, I can't think of anything else that I do with it.   Are these older 3.2.x directories safe to delete if I can reinstall Xcode 4 or will doing so make kittens cry?

How do I get more information why a specific extension is not working and showing me "Error loading extension" when trying to enable it?

Just wiped my hard drive on my MacBook Pro from 2013. Went to install a new copy of MacOS Sierra. I get the following error:  AMD-Action:downloadProduct:SP   I looked online and tried change the date using the Utility Terminal and the following command:  date mmddHHMMyy   Then did   csrutil enable csrutil clear   Then I tried clearing the NVRAM using command + option + P + R on startup.  Still no luck. Still getting the same error message. Apple support told me to go to a "computer repair store".  Any advice?

I'm having the strangest issue since updating to OS X El Capitan. My "Open File" dialogs show the sidebar but all my main (and useful) locations are missing. Take a look at this screenshot. This screenshot shows Keychain Access but this happens in Safari when I'm trying to attach a file to Gmail for example, or uploading an image to Facebook.  What I would like is for the sidebar to show my home directories, such as Desktop, Documents, Downloads, etc.  Help?

I have already read the question about  but this is not what I want, I want to be able to click on the file in Dash or in Nautilus and be able to open it with the specified app.  For example I have this case right now:  When I click on an EXE file it does not get executed by Wine, instead I get the following:    If I try to look for Wine in the Open With context menu option it is there. I am fine executing it from there the first time, but then the following times Wine does not appears selected in the main Context menu:    I then went to Properties to the Open With Tab to look for Wine. It was not in the Default apps nor was it in the Recommended ones when I clicked and search on Show other applications    This is not limited to EXE extensions. It also has happened with MKV files, MP4 files, JPG, PNG, MP3 and even SVG and CSS. So instead of trying to find a way of solving it for one, I want a way that can be done to any type of extension that can:   Make the app the default of that extension Appear on the context menu in Nautilus when I right click on the file Appears on the "Open With" tab on the Property window of the file Correctly executes the specified app when I click on the file with Dash   This might sound like it should be common sense for an app to execute the file but it does not always work like that. So for the cases where it actually does not work, how to fix it. A reset of the extension?, An update of the files that can open said extension?, an addition of the app via a command line or GUI tool?
