1. Amazon Drive lets you free up space on your phone, tablet, and computer, by backing up all of your documents to one secure place. Sign in to Amazon Drive on the web, or through the free iOS and Android apps, and save, share, organize, and store all of your stuff.
2. My Amazon instant video app (Amazon Prime) disappeared and when I try reinstalling it from App Store, it doesn't give me the button to download it. There's no FREE or OPEN button to select. How do I get it back on my iPad? I'm an Amazon Prime member and up until a few days ago, I've used the Amazon Prime app to watch films on my iPad With no.

The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.

If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.

If you want, you can open an app from an unidentified developer. The app may be damaged. Try reinstalling it. If you still can’t open the app, contact the app’s manufacturer. If you recently installed a new version of macOS, some apps may need to be updated or reinstalled to work correctly.

Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.

View the app security settings on your Mac

By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.

In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”

Open a developer-signed or notarized app

If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.

An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:

Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:

If you see a warning message and can’t install an app

If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*

If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.

Can't Open Apps

If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.

You may want to look for an updated version of the app in the App Store or look for an alternative app.

If macOS detects a malicious app

If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.

How to open an app that hasn’t been notarized or is from an unidentified developer

Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.

In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.

The warning prompt reappears, and you can click Open.*

The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.

*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.

You can use Android Debug Bridge (ADB) to connect your development computer to an Amazon Fire TV device or stick for installing, testing, and debugging your apps. Before you use ADB, you must enable debugging on your Fire TV device, and set up ADB on your computer. Follow the steps below.

If you're looking for instructions on connecting to a Fire tablet instead, see Connect to Fire Tablet through ADB.

Here is a video that will explain the basics. For more details, see the rest of the page.

Step A. Enable Debugging on Amazon Fire TV

You must enable both ADB and debugging on your Fire TV device before you can connect to it:

1. From the main screen of your Fire TV, select Settings.
2. Select Device (or My Fire TV) > Developer Options.
3. Turn on ADB Debugging.
4. Turn on Apps from Unknown Sources.
5. (Optional) If your Fire TV supports USB, and you plan to connect your computer to your Fire TV device using a USB cable, turn on USB Debugging. Note that when USB Debugging is enabled, the USB port is unavailable for other uses such as external storage or input devices. To re-enable the USB port, turn off USB debugging.)

Step B. Set Up Android Debug Bridge

Android Debug Bridge (ADB) is a command-line utility for running and managing Android apps on your device or emulator. ADB is available when you install Android Studio, but Windows users will need to install a special USB driver.

You can check to make sure ADB is installed in Android Studio by going to Tools > SDK Manager. Click the SDK Tools tab. Select and install Android SDK Platform-Tools (if it's not already selected).

No action is required for ADB to work on Mac OS X.

If you're on Windows and want to connect your computer to Fire TV through a USB cable, you need to install a special USB driver to connect your computer to a Fire TV device through ADB. The driver supports all the Fire TV platforms. To install the driver:

1. Download the USB file and extract the zip file's contents.
2. Double-click the FireDevices_Drivers.
3. Complete the installation dialog boxes as prompted.

Step C. Add Android Debug Bridge to Your Path

You need to add ADB to your PATH so you can more easily run adb commands. (Your PATH is an environment variable used to specify the location of the program's executable. If you don't add ADB to your PATH, running adb commands will require you to browse to the <Android SDK>/platform-tools directory to run ADB.)

To add ADB to your PATH on Mac:

1. Get the path to your Android SDK platform-tools directory:

   1. Open Android Studio and click the SDK Manager button .The location to your Android SDK appears near the top next to Android SDK Location. For example: /Users/<your username>/Library/Android/sdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

   2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
   3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the adb executable.)
   4. Copy the full path to your clipboard.

2. Use the following command to add ADB to your .bash_profile. Replace <your username> with your actual username. Also, make sure the path points to your Android SDK.

   Your .bash_profile file is usually in your user directory, which you can find by typing cd ~ (change to your user directory). Then type ls -a (list all) to show all files, including hidden ones.

   If the file isn't there, simply create one. You can then type open .bash_profile to see the paths listed.

   After you add this PATH to your bash profile, you should see the following in your .bash_profile file:

   (Only instead of johndoe, you will see your own username.)

3. Fully restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

To add ADB to your PATH on Windows:

1. Get the path to your Android SDK platform-tools directory:

   1. Open Android Studio and click the SDK Manager button .

      The location to your Android SDK appears near the top next to Android SDK Location. For example: C:Users<your user name>AppDataLocalAndroidSdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

   2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
   3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the adb executable.)
   4. Copy the full path to your clipboard.
2. Click your computer's search button (next to Start) and type view advanced system settings.
3. Click View advanced system settings.
4. When the System Settings dialog opens, click the Environment Variables button.
5. Under System Variables (the lower pane), select Path and click Edit.

6. Do one of the following:

   • On Windows 7 or 8, move your cursor to the farthest position on the right, type ; and then press Ctrl+V to insert the path to your SDK that you copied earlier. It may look like this: ;C:Users<your user name>AppDataLocalAndroidSdkplatform-tools. Click OK on each of the three open dialog boxes to close them.
   • On Windows 10, click the New button and add this location.
7. Restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

Step D: Connect to a Fire TV device through ADB

You can connect to ADB either through the network or through USB. Most Fire TV devices only allow network connections, so this is the more common approach.

With this option, you connect using either a wired Ethernet or wireless network connection. Both your computer and the Fire TV device must be on the same network for a network ADB connection to work. All Fire TV devices offer the option to connect wirelessly.

1. Make sure your Fire TV device and your computer are on the same network. You can use either a wifi network or a wired network. You can check the network your Fire TV is on by going to Settings > Network.

2. Now get the IP address of your network. From Settings, go to Device (or My Fire TV) > About > Network. Make a note of the IP address listed on this screen.

   Warning: You do not get the IP address from the Settings > Network screen. There's another Network screen under Settings > Device > About > Network that shows the IP address. Don't confuse the two network screens.

3. Open a terminal window.

   On a Mac, you can open Terminal by pressing Cmd + spacebar and then typing Terminal. On Windows, you open the Command Prompt usually by typing cmd in your program search. (The exact steps vary based on your Windows version.)

4. Run the following command, where <ipaddress> is the IP address of the Fire TV device noted in the previous section. The <port> can be any number within the 5555 to 5585 range.

   For example:

   Note: Make sure you added ADB to your PATH, as described in Add Android Debug Bridge to Your Path. Otherwise you will need to cd to the platform-tools directory first and use./adb on a Mac or adb on Windows to run adb commands.

   The first time you run adb connect, Fire TV will show a screen that says 'Allow USB debugging?'

   If you don't allow USB debugging, Fire TV won't authorize the ADB connection. Select the Always allow from this computer check box, and then click OK.

   If the ADB connection was successful, ADB responds with the message:

   If you need to stop or restart the server, use these ADB commands:

5. Verify that the Fire TV device appears in the list of devices:

   ADB responds with a message like this:

   (where 10.49.172.51 is your IP address.)

If the serial number does not appear after running adb devices, or you get a message saying unable to connect, you will need to troubleshoot ADB.

To connect your computer to Fire TV (Gen 1 or 2) through USB, you need an A-to-A USB cable. Note that you must have a Fire TV Gen 1 or Gen 2 device, not a Fire TV Stick, Fire TV (3^rd Gen), or Fire TV Edition, because only Fire TV (Gen 1 and Gen 2) have a port for the USB cable. If your Fire TV device doesn't offer a USB cable port, use the Network Connect option instead.

1. If you're on Windows, install the USB driver as described in Set Up Android Debug Bridge.
2. Turn on USB debugging. See the section on Enable Debugging on Amazon Fire TV. (Go to Settings. Then select Device (or My Fire TV) > Developer Options. Then turn on USB Debugging.)
3. Connect your Fire TV to a USB port on your computer.

4. Run the following commands:

After the last command, ADB responds with the following message, where <serialno> is the serial number of the device:

Troubleshooting

Can't Get Apps To Open

If you receive a message such as the following:

or

try doing the following to resolve the issue:

• Make sure both Fire TV and your computer are using the same network.
• When connecting wireless with adb connect <ipaddress>, make sure you're typing the IP address correctly, with all the required dots .
• Close Android Studio and any other emulators or USB cable connections.
• Stop (adb kill-server) and restart (adb start-server) the server.
• Restart Fire TV (Settings > Device [or System] > Restart).
• Restart your router.
• See if another service is blocking ADB.
• Read through the Android Debug Bridge (ADB) on Android
• Search online for the error message you're seeing.
