I have a Firefox extension need to write to one files inside the extension's chrome folder, it works fine on windows and linux, but it give me 0x800520015 NS_ERROR_FILE_ACCESS_DENIED error. it is very strange, I manually set the file to have write permission, it works fine then.
My question is where should I set something to tell MAC OS to give write permission to that file.
Thanks.
Which "chrome" folder (post the path)? If you're talking about application's chrome folder, it's a bad idea to write there; newer Windows will not let you do that either.
[edit] so if it's in the extension, you may have the wrong permissions set in your XPI file accidentally. You can change the permissions from your extension (see nsIFile.permissions) or create a proper ZIP while packaging. (Can you post the ZIP file to verify?)
Anyway, why do you want to write to extension's folder? It's usually a bad idea.

I'm trying to implement a file explorer that will display a list of remote files(stored on another network server). And I use QFileIconProvider.icon(QFileInfo) to get the file icon.
The QFileInfo is constructed from a single filename(no path information):
for example: QFileInfo fi("test.jpg");
and that works on both Windows and Linux(I tested it on a Ubuntu machine), but it doesn't work on the macOS. On macOS, I always get the warning
Path given to -[NSWorkspace iconForFile:] is not a full path.
I have checked the solution here: Qt 4.8 - QFileIconProvider, Getting icon for non-existent file (based on extension), but it's for the Windows platform.
I was able to make it work if I created a temporary file on my working directory with the same remote filename. But the temporary needs to be kept. If I deleted the temporary file after calling QFileIconProvider::Icon, I will get the warning above when the QTableView tries to display the QIcon in the UI.
Is there any working solution for my case?
Thanks all.
Since there is no "correctly" solution, I just make a workaround:
Create a temporary file for each file extension, and keep them here, only delete these temporary files when you ensure you don't need them anymore. (I choose to delete them before my app quit.
At least, it works for me.
Thanks!
I was wondering if I can create an autorun.inf file that does not run an .exe file. Intstead, it can open up a web browser or plays a video. How do I go about doing these steps? Of course, I do know that some .inf files can be detected as a virus, but this autorun.inf file I wish to do is clean.
Advice on how to do this is appreciated.
basically, everything you put in the open= portion of the .inf will be opened with the default associated application, or executed.
If you put a web address in there like this :
open=http://www.google.com
it will open google.com in the system's default web browser.
you can (of course) always check the docs Microsoft provides.

can somebody please help! I'm creating audio files using Xcode and placing those files in the 'documents' directory of my app, the point being that I can retreive them using iTunes and File Sharing.
I save the audio files as type .caf, I've created a directory list to make sure that all my files are actually there, they are. I NSLog the directory that the files are being stored to, it's the application documents folder. I have 'UIFileSharingEnabled/Application Supports iTunes Sharing' as TRUE in the info.plist. Everything seems to be working fine, EXCEPT... I just can't see the files in iTunes File Sharing. I KNOW they're there... I can even email them successfully from the same directory, but they don't show in iTunes.
Please can somebody help!
Thanks a lot!!!!
What you're saying doesn't really makes sense.
If you've done all the things you've mentioned properly, you should have had access to the application directory through iTunes.
Nevertheless, considering some problem still happens, you can do the following:
If you have SSH access to your phone (for jailbreak iPhone), you can use SSH to list the files on the documents directory.
If you don't have SSH, you have to solve the problem internally - through your application.
I recommend: List iPhone application document files
I have another question dealing with app sandboxing. So I need access to the users' home directory and at the same time the app should be able to shut down the Mac. This requires to not using sandboxing.
My problem is that I don't know how to remove sandboxing and being able to submit the app to the Mac App Store. I think that the archives are sandboxed because I had turned it on once..
How to remove sandboxing from the archives properly?
Thanks for your help!
On Xcode 11, you can turn off Sandboxing by removing it from the Signing & Capabilities tab:
If I understand what you are asking correctly, you'll need to remove the entitlements.plist from your project and make sure that the Summary view of your target in Xcode has sandboxing turned off:
As Derek Wade pointed out, you can make an App like GarageBand X (which behaves obnoxiously with third party plugins like Amplitube due to Sandboxing) NOT run in a sandbox by editing the binary itself with a HEX editor like HexFiend. Look for:
<key>com.apple.security.app-sandbox</key>
Immediately following that bit you'll see the true tag, which as suggested I switched to 'fals' (no extra bytes) and now GarageBand will happily interact with third party VST plugins. Huzzah.
I found if you go into the .app package, under Contents/MacOS, there should be a binary file that matches the name of your app. Copy that file to your desktop. Edit the desktop copy of the file with TextEdit. You should find within the file, the text representation (xml) of the Entitlements for the app. Find the Sandbox entitlement flag (usually set to <true/>) and change it to <false/>. You will have to unlock the file when editing. Save the file (located on the desktop). Rename the original file in the .app package (i.e. append .old to the filename). Copy the desktop file back to the .app Package location (you may have to authorize it). This should remove the sandboxing.
You cannot remove Sandbox if the user ran you application via Sandbox.
That's the whole point - don't you think ?
I am wondering how an application like appzapper can detect the files related to an application?
All ideas are welcome.
Thanks for your help,
Regards,
By looking into the standard locations that usually are used by applications to store preferences (like Library/Preferences/ , Library/Caches, etc., both in your home directory ~/ and under / ) I couldn´t find any file or folder that isn´t using either the applications name (eg. ~/Library/Application Support/Firefox) or it´s bundle identifier (eg. ~/Library/Preferences/org.mozilla.firefox.plist) in its name; so I guess they´re just using that.
In the case of AppZapper you can go ahead and try for any (not currently running) Application to rename the ~/Library/Application Support/AppName folder for example to ~/Library/Application Support/111AppName - AppZapper doesn´t find it anymore. If you change it to ~/Library/Application Support/AppName111 it shows up as a related file.
Out of this you can conclude that there isn´t any magical linkage between a folder full of preferences and it´s associated application that AppZapper is reading out, it´s merely checking for folders starting with the Application´s Name.
