Symptoms

  • With the Silverlight tool, you can create some powerful web applications. For running such apps on a Mac OS, Windows or Linux, you need a suitable plugin for Silverlight. But if you installed the program by mistake and now want to remove it, here are 2 ways to uninstall Silverlight on Mac. Contents: Uninstall Silverlight.
  • Uninstall Microsoft Silverlight. Microsoft Silverlight does not work as expected. Attempts to restart the computer and try to upgrade, install or uninstall Microsoft Silverlight again end in the same results. This issue can occur if an existing installation or uninstall has become corrupt. To automatically uninstall Microsoft.

The Official site of Microsoft Silverlight. Download and install the latest version Microsoft Silverlight plug in for your browser. Sep 27, 2018 I am using Firefox ESR 52.1.0 on a MacBook. I was on Mac OS High Sierra and Silverlight was working on Safari until I installed Safari 12. At that point Firefox ESR 52.1.0 still ran Silverlight. I along with other users of a company Silverlight application have updated to Mac OS Mojave. Why migrate Silverlight applications? Silverlight is only supported on Internet Explorer, and Microsoft has announced that it will stop the support entirely on October 2021. Why migrate WPF applications? WPF only runs on Windows. It doesn't run on Mac OS, it doesn't run on Chromebooks, and it doesn't run on mobile devices.

Microsoft Silverlight For Mac Catalina 2020

When you try to access a Web site that requires Silverlight to display the content, you receive an error message that states that you have to install Silverlight.

Cause

Microsoft Silverlight Download

This behavior can occur for several reasons:

  • Your system has an earlier version of the plug-in and does not meet the requirements for the plug-in that the site is using.

  • You do not have the plug-in installed.

  • The browser is set to 'Run using Rosetta,' which will cause the computer to be identified incorrectly as a PowerPC-based Mac.

Resolution

Before you determine how to address the issue, you should assess the current environment in which the software is running. To do this, follow these steps:

  1. On the Apple menu, select About this Mac.

  2. Note the processor type, speed, RAM, and operating system information, as some Web sites have specific requirements to view their content.

  3. Close the window.

  4. Close all open browser windows.

  5. Double-click the hard drive icon on the desktop.

  6. Double-click the Library folder.

  7. Open the Internet Plug-ins folder.

  8. Is there a file that is named Silverlight.plugin? If this file exists, the plug-in is installed. To determine the version, click to select the file. Then, select Get Info on the File menu. Note the version number that is displayed.

    • If the version number that is displayed is 1.0.xxx and your processor type is a PowerPC, you have the correct version of the plug-in installed.

    • If you have an Intel Processor, all versions of Silverlight are supported. But we recommended that you run the latest version so that you can access Web sites that use the newest features and take advantage of the most recent product improvements.

Now we can address the individual causes and resolutions.

Your system has an earlier version of the plug-in and does not meet the Web site's requirements

The most common cause of this issue is that the Web site is using Silverlight 3 for its content. If a site requires version 3, it recognizes whether your system meets the requirement. If the system does not, you are prompted to upgrade. You are directed to the Silverlight site. If you are using a PowerPC, the site recognizes this and that only version 1 can be installed. (This situation would have to be addressed by the Web site's support team, as the decision on what version of Silverlight to use is made by the Web site designers.)

You do not have the plug-in installed

If Silverlight has not yet been installed, follow these steps to install the plug-in:

  1. Start a Web browser, and then visit the following Web site:

  2. Locate the 'Install Silverlight' area in the lower-right part of the window.

    • If you are running an Intel processor, click Mac Runtime next to 'Silverlight 3.'

    • Otherwise, click Runtime for Mac PowerPC next to 'Silverlight 1.0.'

  3. After the download is completed, installation should start automatically. Follow the steps in the installation wizard.

  4. After the installation is complete, you should be prompted to exit your browser. Close any browser windows, and then restart the browser. The browser should recognize the new plug-in.

Note If you have any problems with the installation, see the following Microsoft Knowledge Base article for information about how to manually install the plug-in:

970064 How to remove and manually reinstall Silverlight 2 for Mac

The browser is set to 'Run using Rosetta,' which will cause the computer to be identified incorrectly as a PowerPC-based Mac

If the browser is set to run in the Rosetta engine, it will incorrectly identify the computer as a PowerPC-based Mac, or the Web site will not recognize that the appropriate plug-in is installed.
If the appropriate plug-in is installed as described in the previous section, follow these steps:

  1. Double-click the hard drive icon on the desktop.

  2. Choose the Applications folder.

  3. Find the icon for the browser that you are using. Hold down the CONTROL key while you click this icon.

  4. Select Get Info.

  5. Locate the Run using Rosetta option and make sure that this check box is not selected. If it is selected, click to clear the check box. Close the window.

  6. On the Apple menu, click Restart.

  7. After the computer restarts, again try to access the Web site that generated the error message.

Note If the appropriate version of the plug-in is not installed, make sure that the Run using Rosetta check box is not selected, and then follow the steps in the previous section to install the plug-in.

Flashpoint's Mac support is heavily experimental. This page provides information about the current Flashpoint for Mac package.

Microsoft Silverlight For Mac Catalina 2019

Flash EOL Screen

If you see the Flash Player EOL information screen when you try to play a game, that means that SeaMonkey is loading your installed Flash Player plugin instead of the plugin that is bundled with Flashpoint. To fix the problem, uninstall Flash Player from your Mac and restart Flashpoint. Games should work again in SeaMonkey.

MacOS Catalina and Big Sur

Because Flashpoint's applications are from an 'unidentified developer,' if you're using Catalina or Big Sur, you'll need to approve each application before it can run. Open your system preferences, click 'Security & Privacy', then allow each of the following applications to run: StartFlashpoint.command, Flashpoint Launcher, swfbbox, and SeaMonkey. If you have trouble figuring out how to do this, watch this tutorial video.

Because Adobe Director Projectors are 32-bit applications, SPR for Mac will not work on MacOS Catalina or Big Sur. This means that Flashpoint for Mac does not support Shockwave games on Catalina or Big Sur.

MacOS Big Sur (MacOS 11.0)

Flash applications have been successfully tested and are working. To use Flashpoint with Big Sur, a few modifications are required. Follow the steps below:

  1. Download SeaMonkey 2.53.4 for MacOS x64 from here: https://www.seamonkey-project.org/releases/2.53.4
  2. Open Flashpoint Infinity's FPSoftware folder, then find the old 'SeaMonkey.app' there.
  3. Right-click the old SeaMonkey.app and click 'Show Package Contents.'
  4. Open the Contents folder, then within that folder, open the Resources folder.
  5. Find the folder called plugins and copy it.
  6. Find the new 'SeaMonkey.app' file that you downloaded by searching in Finder under 'This Mac'.
  7. Right-click the new 'SeaMonkey.app' and click 'Show Package Contents.'
  8. Open the Contents folder, then within that folder, open the Resources folder.
  9. Paste in the plugins folder that you copied earlier.
  10. Go back outside of the new 'SeaMonkey.app' package and copy it.
  11. Open Flashpoint Infinity's FPSoftware folder, then paste the 'SeaMonkey.app' file that you just copied. Replace the original file when prompted.

Apple Silicon Macs

To run Flashpoint on Macs with the new M1 chip, you'll need to install Rosetta by following these instructions. Once you've done that, follow the instructions in the previous sections to get Flashpoint working.

Installing Java

To add support for Java games, you'll need to install the Java Development Kit. Follow the steps below:

  1. Download JDK version 8u212 from here: https://github.com/frekele/oracle-java/releases/download/8u212-b10/jdk-8u212-macosx-x64.dmg
  2. Open the DMG file and run the installer. Follow the on-screen instructions to install the JDK.

Installing Wine

Running games in Wine is not yet supported, but we hope to add support for this in a future build. If you'd like to contribute to our efforts, you can download an installer here.

Uninstall Microsoft Silverlight Mac

Using Flashpoint with Automator (optional)

You can start Flashpoint without having to click on StartFlashpoint.command by using Automator using the below steps:

  1. Choose File > New.
  2. Select 'Application', then click Choose.
  3. Drag the Run Shell Script action into your workflow.
  4. Enter open /Users/[YOUR USERNAME HERE]/Downloads/Flashpoint Infinity for Mac Beta/StartFlashpoint.command in the command field.

Technologies

Currently, only Flashpoint Infinity is available for Mac. However, as explained here, both PHP and Apache are included with MacOS. This means it should be fairly simple to create a Flashpoint Ultimate package for MacOS as well. Let us know in our Discord if you can help!

No equivalent to the Flashpoint Redirector currently exists for MacOS. MacOS also does not provide any native way to set per-application proxy settings. In Flashpoint for Mac, the proxy settings for each supported technology must be set separately. This rules out using the Flash projectors, since they do not have configurable proxy settings. In Flashpoint for Mac, all Flash games run in a browser.

The Flashpoint FAQ contains a list of all web game technologies ('Platforms') supported in the Windows version of Flashpoint. The Mac version currently supports a small subset of these platforms. This is explained in detail below. The list of supported platforms includes an unscientific estimate of the percentage of games supported by our method.

Supported Platforms

  • Flash: Supported using the SeaMonkey web browser, with a Flash plugin included. Games that use a Flash Player version other than 32 are not yet supported.
    • ~95% of games supported.
  • Shockwave: Supported with SPR for Mac. Because LeechProtectionRemovalHelp is only available for Windows, the majority of Shockwave games will not work properly.
    • ~30% of games supported.
    • Requires a 32-bit compatible OS; Catalina is not supported.
  • HTML5: Supported using the SeaMonkey web browser. WebAssembly support is enabled in Flashpoint's SeaMonkey profile, so it should be compatible with nearly all of the same games as Basilisk.
    • ~99% of games supported.
  • Java Applets: Supported natively using the JDK. Java in the browser is not supported yet.
    • ~99% of games supported.

Unsupported Platforms

  • Unity Web Player: Has not been attempted yet. We would need to track down the Mac builds of all 12 versions of Unity Web Player that we support on Windows. Needless to say, this would be a huge challenge.
  • PopCap Plugin: As far as we know, there is no version of PopCap Plugin for modern Macs.
  • Authorware Web Player: Authorware is incompatible with all Intel Macs.
  • GoBit Plugin: As far as we know, there is no version of GoBit Games Plugin for modern Macs.
  • Silverlight: Silverlight for Mac is available here, but as explained in this StackExchange answer, Microsoft Silverlight for Mac is 32-bit only, even though the Windows version has 64-bit and 32-bit versions. This is a problem because no major browser for MacOS has a 32-bit version, and MacOS Catalina drops support for 32-bit programs entirely. As such, Silverlight is unusable on Mac.
  • 3DVIA Player: As far as we know, there is no version of 3DVIA Player for modern Macs.
  • 3D Groove GX: 3D Groove is incompatible with all Intel Macs.
  • ActiveX: ActiveX is a Windows-only technology.
  • ShiVa3D: The Windows version of the ShiVa3D Player is available in the free ShiVa Web Edition; this is where we obtained it. However, no Mac version of the ShiVa Web Edition is currently available, so we haven't been able to find a Mac version of the ShiVa3D Player. It's possible that we could extract a Mac version of the player from a Mac version of a ShiVa3D game. Or maybe we could obtain the Mac runtime from the Windows version of ShiVa3D Web Edition, since it has the capability of publishing for Mac.

Launcher Issues

A number of Flashpoint Launcher issues affect the experience of using Flashpoint Launcher on MacOS. Unfortunately, none of our Launcher developers currently have access to a Mac, so updates for the Mac version of Flashpoint Launcher will not be available in the foreseeable future. We will be unable to release a Mac version of Flashpoint 7.0 until a new version of the Launcher is built for MacOS. If you have access to MacOS and are able to build Flashpoint Launcher, please let us know!

The current issues with the Mac version of Flashpoint Launcher are listed below.

  • Errors are shown in the log when services are missing from the services.json. These services are unnecessary for Flashpoint on Mac, so the errors can be ignored.
  • Flashpoint Launcher cannot find its own Version file, even if it is present in the Launcher's folder and app package.
  • The Theme dropdown menu on the Config tab does not work properly. To select a theme, you must manually type the path to the theme's CSS file.
  • A popup appears if the user attempts to start a Windows executable from Flashpoint. This popup tells the user to install Wine, and points them to the Linux Support page, even though the Launcher is running on Mac.
  • If a shell script is specified in execs.json as an alternative to a batch script, the Launcher will attempt to launch the shell script defined for Linux, even if a different shell script is defined for Darwin (MacOS).
  • Flashpoint Launcher attempts to load the hidden resource forks of certain files as separate files. These files are not visible in the MacOS Finder, and have filenames beginning with ._.
    • If any Platform XML has a resource fork, all of the Platform XMLs will fail to load, causing a 'No games found' error.
    • If any localization JSON file has a resource fork, a 'NotValidJSON' error will appear in the logs.
  • When Wine is started from Flashpoint Launcher, it uses >70% CPU for several minutes without ever starting the intended executable. This is despite Wine working fine when started from the terminal. This issue needs to be investigated and solved before Flashpoint can support launching games through Wine.
  • By default, Flashpoint Launcher will attempt to read and modify config.json and preferences.json inside its own app package. Since Mac applications are not allowed to modify their own app packages, this will fail. For this reason, Flashpoint Launcher must be opened with a shell script command StartFlashpoint.command. This script sets the current directory to the Flashpoint Launcher folder so that the Launcher accesses the config.json and preferences.json in the correct location. However, this unusual way of opening the Launcher may be the cause of the previously mentioned Wine bug.

Other Notes

  • Some keyboard controls such as the spacebar or WASD keys may not work in some games. This is a known problem with the NPAPI Flash plugin on MacOS. We plan to resolve this problem in the next build of Flashpoint for Mac by using the PPAPI plugin instead.
  • Flash games with URLs pointing to filenames with special characters will not work. This is because nosamuEmbedSWF.sh does not properly handle special characters when it converts URLs to paths, so it cannot copy the game's HTML to the correct location in htdocs.
  • Some Shockwave games may not close when you quit them from the menu. If this occurs, click inside the Message Window next to the game. Then type quit and press Enter to close the game.
  • Flashpoint for Mac uses exec mappings to determine what native executable to run based on the specified Windows application path. For example, flashplayer_32_sa.exe is mapped to nosamuEmbedSWF.sh for MacOS. To add more exec mappings, navigate to Flashpoint's Data folder and open execs.json in a text editor. The exec mappings use 'darwin' to refer to MacOS.
  • Flashpoint for Mac uses swfbbox to determine the width and height of an SWF file. swfbbox is part of the swftools homebrew package. To install swftools, first install homebrew. Then type brew install swftools in the terminal.
  • Flashpoint for Mac requires that PHP and cURL are enabled on your system. These components should be enabled by default.

Packaging Flashpoint for Mac

Here are some steps to keep in mind when packaging Flashpoint for Mac. This assumes that you are using the current package as a base and modifying it.

  • You can follow these instructions to update Flashpoint's XMLs to the latest version.
  • You can follow these instructions to update Flashpoint Router to the latest version.
  • Use update-spr.sh in the FPSoftware folder to update SPR to the latest version. To get the latest version of SPR for Mac, see SPR for Mac.
  • If you would like to distribute a modified SeaMonkey profile, be sure to clear the cache, cookies, and other data. In SeaMonkey, click Tools -> Clear Private Data.
  • If you would like to add a plugin to SeaMonkey, first install the plugin normally. Then, follow these steps:
    1. Navigate to /Library/Internet Plug-Ins in Finder and copy the files for the plugin you want to add.
    2. Navigate to Flashpoint's FPSoftware folder. Right-click SeaMonkey.app and choose 'Show Package Contents.'
    3. Inside the app package, navigate to /Contents/Resources/plugins. Paste the plugin files that you copied in Step 1.
  • Before running or distributing Flashpoint, you should run the dot_clean command inside the Flashpoint folder to remove resource forks. Flashpoint Launcher may not work properly if Flashpoint files have resource forks, as explained in Launcher Issues.
