How do I open apps downloaded from the internet on my macbook?

I downloaded an app from the Avery website to create labels. When I download the app and try to open it i get a garbled message. Any idea how I can open the app?

I was not given an option of which to download. I have this problem all the time and someone told me how to fix it once, but I cannot remember what the answer was.

Can't open any apps downloaded from the internet after installing application loader update and messages beta

I've run into an unusual problem recently. I think it it related to two recent software installs.The problem only started after i installed the new application loader.
My issue : I'm unable to open application I downloaded from the web. I get the following error message below.
Question: Has anyone else run into this issue and do you have a solution?
Thanks for you help.
P.S I haven't tried rolling back the lastest softwarte installs yet. I'm hoping I can avoid that.

When I press cancel nothing happens. I can do nothing and it still won't load the program.

Downloading from the internet to my macbook pro

HI I could use some help please. everytime I download something from the internet and I chose to save it, it doesn't give me the option to save it to my desktop or a folder it just automatically download it to the download folder. I have another macbook pro same exact specs and it allows me to make a choice to where I want to save the item. Anyone know where I can change this setting and how to do it. I am computer illiterate so I do know how to navigate around a computer I just can't seem to see where the settings are different between the two computers. Thanks for any help anyone can give!

Welcome to Apple Discussions
I assume you're using Safari - so open Safari/Preferences/General and under 'Save downloaded files to' set the location you prefer.
Another option is to control/click on a download link and you'll then get a pop-up menu where you can select 'Download linked file as' and chose the destination.

How do I save images downloaded from the Internet?

I have the URL to an image stored on the Internet. Is it possible to open a connection and store the image on my computer? I'm not totally new to this, I've written a small program that could read text files from an ftp server, but it's my first try at downloadning images. Here's the code I'm using
String wwwfile = ....;
               System.out.println(protocol+host+wwwfile);
                    URL url = new URL(protocol+host+wwwfile);
                    URLConnection urlc = url.openConnection();
                    InputStreamReader reader = new InputStreamReader(urlc.getInputStream());
                    File file = new File(path,fileName);
                    OutputStreamWriter writer = new OutputStreamWriter(new FileOutputStream(file));
                    int c;
                    while((c = reader.read())!=-1)
                    writer.write(c);
                    reader.close();
                    writer.flush();
                    writer.close();
When I read text files, I used BufferedReader/PrintWriter instead of InputStreamReader/OutputStreamReader. The picture I want to download seems to be downloaded, it's stored on the computer, but upon viewing the picture, the browser displays the icon telling me the picture is abscent.
What is it that I'm doing wrong?
regards
simon

Ah, this might be the problem. You're using an InputStreamReader and OutputStreamWriter to wrap the streams with reader/writers. This is bad. This will corrupt binary data.
Try this:
        System.out.println(protocol + host + wwwfile);
        URL url = new URL(protocol + host + wwwfile);
        URLConnection urlc = url.openConnection();
        // Use InputStream/OutputStreams instead of Reader/Writers for binary data.
        // Otherwise it will get corrupted.
        InputStream in = urlc.getInputStream();
        File file = new File(path, fileName);
        OutputStream out = new BufferedOutputStream(new FileOutputStream(file));
        int c;
        while ((c = in.read()) != -1) {
            out.write(c);
        in.close();
        // You don't have to flush the file if you're
        // closing it right after.
        out.close();

How do I disable this - "Firefox.app" is an application downloaded from the Internet. Are you sure you want to open it?

how do I disable this - “Firefox.app” is an application downloaded from the Internet. Are you sure you want to open it?

If you want to open it confirm that you do. You will not be asked that question again after the first time you open it
Unless you are keeping Firefox in the .dmg it was downloaded in. That is to say, if you obtained Firefox in a .dmg, and you have kept the .dmg mounted, and are launching Firefox from the mounted .dmg, then you will ALWAYS get that warning. You should copy Firefox from the mounted .dmg to your Applications Folder (or anywhere you prefer), and then eject the mounted .dmg. Unless you need to install Firefox on another system, you can then delete the .dmg.

WZZZ,
Thanks, the following command (ran as root) worked for me!
xattr -d com.apple.quarantine /Applications/Google\ Chrome.app
Chrome is set to start on launch, so I'd get the following warning on every start/restart

How do I stop click-thru "'Firefox' is an application downloaded from the Internet. Are you sure you want to open it?"?

Every single time I launch Firefox 20 under Mac OS X 10.7.5 I get the click-thru warning message "'Firefox' is an application downloaded from the Internet. Are you sure you want to open it?". How do I stop this? There are internet postings and previous postings about solving this using Terminal commands for OS X 10.5.x & 10.6.x, but these commands do NOT work in 10.7.x or 10.8.x. This seems to be a Firefox ONLY issue, and solving it by globally turning off OS X security features as recommended before in a previously closed thread seems like a really BAD solution. Is there a "Firefox only" solution, or will I just have to stop using Firefox?

I had upgraded to Firefox 20 using the automatic update process, so the last time I'd downloaded a .dmg and manually installed Firefox was a long time ago. I trashed Firefox 20, downloaded a new .dmg and manually transferred to Applications folder and this persistent message ended. I assume if I'd ever launched from the open .dmg the same error message would result, so the fix offered was a solution even though the cause was something different since I only used the automatic update process and never manually handled Firefox .dmg downloads.

"Firefox.app" is an application which was downloaded from the Internet...

This is a topic that has been posted before but I'm creating a new one because the previous discussion is closed and none of the answers solved my problem.
Each and every time I launch Firefox, I receive the following warning, - “Firefox.app” is an application which was downloaded from the Internet. Are you sure you want to open it?"
For the record, I have tried the following fixes with no success:
- Removed the Firefox folder from user/library/application support both as a user and as an admin.
- I logged in to the Mac as an admin. and launched Firefox. The message continues to pop up after doing this, while still logged in as admin.
- I logged in to the Mac as an admin, went to Terminal and listed the attributes. The "com.apple.quarantine" attribute does exist, however, when I tried removing it with (xattr -d com.apple.quarantine <FILE NAME>), I am told that the attribute DOESN'T exist. Huh?
I am trying to avoid completely removing Firefox and doing a fresh install but it may come down to this. Any help would be greatly appreciated.
Thanks!

I had a similar problem with another application. I downloaded an update to an application from the developer, and then got this message every time I ran the program. There's a script to disable this behavior entirely on MacWorld's macosxhints site.
I didn't want to disable this behavior for good, just for this one program. I realized that I had downloaded it as one user, but the first use (of the update) was as a different user. I logged in under the user ID that I used when I downloaded the application and ran the program. After that, the warning went away.
My guess is that you did something similar. Log in as the user ID you used when you first downloaded the updated FireFox and run the program. The warning should go away.
If you can't remember which user ID you used, try the brute force approach - log in as each of your user IDs and run FireFox.
Good luck!

"........" is an application which was downloaded from the Internet. Are you sure you want to open it?

I get the following warning every time I try to open a recently download application. I'm running Mavericks 10.9.3
"xxxxx' is an application which was downloaded from the Internet. Are you sure you want to open it?
How do I disable this warning for a particular application?
Update: problem solved. The Mac in question has multiple users, but only one user has administrator privileges. The problem was simply that the application in question had never been opened by the administrator. Once the administrator opened the application the warning went away.

If using a mouse, you can right click on the application installer this will give you an "Open with" popup and you can chooes to open the application installer using the standard installer.
Another method to do the same exact thing is to hold the Control key while left clicking on the Application installer will give you the exact same popup menu.

Are you launching those apps from a different user account than the account that downloaded them?
From
About file quarantine in Mac OS X v10.5 and v10.6
If you have multiple user accounts on your Mac, the user account that downloaded the file is the only user account that can remove the quarantine attribute to the file. All other user accounts can open the quarantine file, but they will be presented with the quarantine dialog box asking "Are you sure you want to open it?" every time they open the file.

Gatekeeper Open Apps Downloaded from anywhere issue

Hi,
I've configured the gatekeeper to open apps downloaded from anywhere, howeverm everytime I open any app downloaded form internet it always asks the Acept/Deny question, it seems like it's bypassing the System Preference Gatekeeper settings.
What can I check?
Cheers,

The database in which Gatekeeper stores its settings may be corrupt. This procedure will reset all Gatekeeper settings to their defaults. Any changes that you made will be reverted, but can be restored from backup if there's no improvement.
Back up all data.
If you have more than one user account, you must be logged in as an administrator to carry out these instructions.
Triple-click anywhere in the line below to select it:
sudo cp /var/db/.SystemPolicy-default /var/db/SystemPolicy
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning not to screw up. Confirm. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Quit Terminal, reboot, and test.
