I know the trick with "show package contents" and I've gone to: $ECLIPSE_HOME/Eclipse.app/Contents/MacOS
However, the file in there is 'eclipse', rather than 'eclipse.ini'
Furthermore, when I open this file, sublime suggests that this is an application and shows me the hexadecimal values…
When I switch to UTF-8, I can see SOME English but most of it is still garbled…
How to open this file properly (and why it's not .ini like all of the internet says it is?)?
NSBundle and CFBundle aggressively cache the contents of application bundles to improve performance. Although you edited the Info.plist, the Finder and Launch Services don't yet know that the application is any different.
Running the following command in Terminal to touch the application bundle will force the Finder (and Launch Services) to re-register the application, thereby noticing the changes you made to the Info.plist:
touch "/Applications/My Cool App.app"
After running that, deselect the application, then reselect it in the Finder, and then try launching it.
Note that this won't necessarily guarantee that you'll be able to launch the app. The developer would need to make sure they set a deployment target of 10.4 and/or use weak framework linking to assure that the app will be fully backward-compatible.
Download the dmg from Adobe's website. Mount it and right click on the Install Adobe Flash Player.app and select "Show Package Contents."
Drill down into Contents > Resources:
Launch the Adobe Flash Player.pkg:
When the plugin installer launches, go to File > Show Files (or CMD + I).
There you will see a list of the files it installs and where. You'll need to use something like Pacifist to extract the contents, but once you do, you can install the files manually. And yes, the install would be just as clean if you used the pkg to install the plugin. It's not any safer, it's just an alternate route that doesn't have the Adobe wrapper (so it doesn't use Adobe's proprietary installer).
Best Answer
Well, I've gone crazy and actually searched for the eclipse.ini file. I've actually found it in:
/Eclipse.app/Contents/Eclipse
It's amazing how much advice on the internet (including eclipse.org!) points to:
/Eclipse.app/Contents/MacOS
It must have been true at some point but perhaps with newer versions, this is not necessarily true anymore, which is why I would like to keep this question and this answer despite the basic mistake - in order to inform other people with the same problem.
