My Delphi Firemonkey MacOS app makes documents with a .4MD extension.  How can I get my app to launch when the user double clicks on Finder documents with a .4MD extension?  The seemingly duplicate question on Stackoverflow has an answer with a dead link to Apple's documentation.   This article has answers for Delphi XE2:

I would like to associate the last installed version of my Mac OS X application with a certain type of file. A little experimentation shows that the info.plist file seems to be read and interpreted by the operating system when launching the application, not when dragging the application bundle to the disk.  does not say much on that topic.  Is there any way, using a simple .dmg image as installation medium, to make sure the system associates that particular file type with my newly installed app without having to launch it first?  I should clarify that I want this to be done automatically during the installation (I don't want my users to have to do it themselves).

I have been peaking in macOS Activity Monitor and found this:  One tab spawns atleast 3 processes:   Firefox ~400MB FirefoxCP Web Content ~200MB FirefoxCP Web Extensions ~200MB     Update - ran again and got these numbers ...

My problem is that when I try to open one specific .odt document, I can't move the page or do anything except moving the mouse, which is useless. Also, the mouse, when I'm on the document, is freaking out switching between mouse and loader couple of times per second. It also becomes dark when I click on the document like if it's not responding.

I have an MXD that someone else has created. They have put some sort of lock on the extent that stops me from zooming and panning. I can't for the life of me work out how to turn it off.   Does anyone know?

I work with hidden files all the time, but I like an uncluttered desktop. It would be nice to make files like .DS_Store, and .localized invisible just on the Desktop.  Please note I am already aware of this trusty old terminal standby:  defaults write com.apple.finder AppleShowAllFiles TRUE killall Finder   Setting that flag to FALSE applies to everything in the system. My goal is to make an exception for the Desktop. Any suggestions?

I would like to create a Delphi application for Windows XP which allows dropping of files dragged from Windows Explorer (the Desktop or folder windows) or other applications which support this operation (such as Total Commander). What about vice-versa? When the user drags an icon from my application, I should be able to set the contents of the dragged object to custom data.  My goal is to create a custom application toolbar, onto which I can drop applications and show their icons or drag applications or other entities from it.  How can this be done?

I would like to mimic the use of Alfred on Mac OS X, where if you try to open an app after searching for it, it will only open a new window if the program is not already running, otherwise it will set the focus on the currently running instance of that application. Is there anyway to change the default behavior of the launcher to check for this before opening a new window?

Is it possible to fine-tune the "Open safe files after downloading" setting in Safari? For example, to make Safari open files like ".ical" et. al., but not Zip-files.  If macOS has no built-in support for this, could a solution be a UNIX script daemon that instantly detects new files in the Downloads directory and opens files with certain extensions?

My aim is to update the look of the GUI in my app. Currently my GUI contains a lot of listboxes which are used to edit some objects in an old fashioned way, that is, user double-clicks an item and a dialog is shown to modify the corresponding object.   I think a good modern approach is how Firefox displays the extensions installed (a snapshot below).   My question is about how to build such a GUI in Delphi(win32) easily? Are there any components you use mimicing such behaviour or will I just need to code this from stratch using panels? (IMO a very cumbersome job I'd like to avoid - the selection logic, resizings, etc...)

Call me crazy, but I'm sure I remember this capability existing in previous versions of Windows.  In Windows 7, we can have file extensions Off... or On.  Pick one.  Is there some obscure switch buried in the registry to have Explorer show specific extensions, but leave the rest hidden?  In my case, I'd like to always show extensions for text files (*.txt, *.csv, *.tdt), because I frequently have to handle flat files which may come in with a .txt extension where I need it to be .csv, for example.  I'd rather not have extensions on all the time, it's just clutter for almost all files.

What are all of the ways a keyboard shortcut could be bound in Safari?  I am aware of the following:   The app’s own standard shortcuts System Preferences > Keyboard > Shortcuts >   App Shortcuts >   All Applications Safari  Services  Safari Extensions KeyBindings.dict 3rd party utility applications   Alfred FastScripts Keyboard Maestro    Are there other obvious paths I could be missing? Are there ways of figuring out how a specific keybinding is being handled?  For context, I created a utility shortcut for myself to send the current Safari tab to Chrome by pressing ^c. I did this a few years ago with an Alfred Workflow, with a Hotkey trigger scoped to com.apple.safari and a simple AppleScript to get and reopen the front tab's URL.  Great. However, changing the keybinding of this workflow today I discovered that it also seems to be captured by something else I set up at some point (and bound to basically the same action). With the Alfred workflow disabled, its keybinding changed, or Alfred itself quit and not running, I have verified that the Alfred version does not run, but something else is triggering the page to open in Chrome.  I do not have FastScripts or Keyboard Maestro on this Mac. I do not see any bindings for this key in the System Preferences. I do not have /Library/KeyBindings/ or ~/Library/KeyBindings/ folders on this Mac. I don’t see any bindings in any of the areas of the Keyboard > Shortcuts preference pane. There don’t seem to be any plausibly-related Safari Extensions installed.  Shortcut Detective can detect when Alfred catches a keybinding from Safari, but sees nothing when the still-caught ^c is handled by whatever else is grabbing it.  I can’t for the life of me figure out where else I managed to bind this shortcut, and therefore can’t figure out how to unbind it short of wiping my account.

Is it possible to build a .dmg file (for distributing apps) from a non-Mac platform? And if yes, how?

find . -name *.jks -print 2&gt;/dev/null   returns files of extension jks that do not have underscores as part of their name.  Much to my surprise, I have just discovered that * does NOT substitute the underscore.  find . -name *_*.jks -print 2&gt;/dev/null   returns files of extension jks that have one underscore.  How do I search for files that have 0 or more underscores?  Using OSX Mountain Lion.

I went to their site, and downloaded a .bundle which automagically turned into a .txt file after downloading.   Long story short, I can't run the txt file because I guess Mountain Lion Mac os X isn't a strict Linux box and is missing some core components to do that type of installation.  Does anyone know how to install VMware?
