Silverlight thinks my Intel Mac is a PPC and won't install.

  • Question
  • Updated 7 years ago
Downloaded the Silverlight installer from silverlight.net (Silverlight.2.0.pkg), but when it checks my system it gives the error:

Microsoft Silverlight Browser Plug-In cannot be installed on this computer.
Silverlight 2 may not be installed on PowerPC.

My computer is an iMac with a 2.16 GHz Intel Core 2 Duo running Mac OS X 10.5.5

Netflix streaming for Mac is coming, and I just heard that they are using Silverlight. Missed out on the Olympics coverage from NBC because of the Silverlight issue. Hoping to correct it for Netflix.

We've seen this in some Safari plugins that seem to be changing the way Safari is behaving and identifying itself. To fix this, quit Safari, find Safari in the Applications directory, and choose “Get Info”. Find the box called “Open using Rosetta” and uncheck it. I hope this works for you.

That "sort-of" works. It tricks the MS Silverlight page into thinking I'm running a PPC, so it feeds me the 1.0 version of Silverlight, which installs fine.

However, this doesn't solve the problem with version 2.0 of the Silverlight installer thinking that I don't have an Intel Mac.

It doesn't seem to have anything to do with Safari. Maybe I'm wrong. Once I've download the 2.0 installer, I can quit Safari and try to run the installer and I still get the error. I have the latest Safari version (3.1.2) installed, and the latest OS X system update. Maybe there's another installed plug-in that's causing the problem?

Frustrating. Just wish there was a way to ignore the error message and force the installer to install anyway. The code should run, since I REALLY do have an Intel Mac.

I'm also running into the same problem. What does the installer look at to tell what CPU the system is running? I assume it would try to do a uname or sysctl to verify the cpu but that is me coming for a unix environment.

Hi Roncioiu and Rogue3675 -- I've been working with Jeff offline on this. Here's some instructions to see if that will get you a workaround:

The installer does the following to check the CPU architecture.

system_profiler SPHardwareDataType -xml | grep "Intel"

If you open a shell and run system_profiler SPHardwareDataType – what does it report for “Processor Name”?

If you know for a fact that you are on Intel and want to complete the install, it is fairly easy to disable the checks done by the installer (the steps are somewhat dependent on which browser you are using so I’ll just paste these in to get started but let me know if you need more info).
1. Download the Silverlight 2 for Mac OS X.
2. Let the .dmg file execute.
3. Go to the folder where you downloaded the Silverlight plugin.
4. Right click on "Silverlight2.0.pkg" and choose the "Show Package Contents" menu item.
5. Double click on the "Contents" folder.
6. Double click on the "Resources" folder.
7. Drag and drop the file "InstallationCheck" to the trash.
8. Close out the folder you're working in.
9. Finally double click on the "Silverlight2.0.pkg" package, and it should install fine now.

This is Eric again... removing the InstallationCheck was even easier than creating a fake system_profiler (though, it would be even easier if Microsoft simply didn't bother with the check).

roncioiu and Rogue3675,

I ran the shell command (above) and it reported that I had an Intel processor. Not sure why the installer doesn't continue if this is supposed to be the check.

The instructions that Tim gave above worked for me, though. Once I got rid of the "InstallationCheck" file, the installer worked perfectly. I'm now running Silverlight 2.0 and enjoying the new Netflix Streaming Beta for Mac! :-)

Hi, I just installed Silverlight. It seems to have installed just fine but when I reload the web browser and try to stream the video it just goes back to the install page. It's as if Safari does not recognize that I have installed Silverlight. How can I fix this?

Kimberly, can you tell me what site you are accessing it? Some site authors probably need to fix their site.

Thank you for your reply. I got it to work by following the above directions. I'm still pretty new to Mac and still learning the "lingo" if you will so I didn't quite understand if that was the problem. But I tried it and it worked. Thanks though. I appreciate your help. :)

Kimberly, while in Safari, go to the "Installed Plug-ins" item under the "Help" menu and see what version of Silverlight was installed in your browser.

It could be that Silverlight 1.0 was installed, in which case visiting the Silverlight page will return you to the "install" page, because it is trying to get you to upgrade to 2.0. I had this problem because the Silverlight website saw that my system was capable of running version 2.0 (must have an intel processor), but I was only able to install version 1.0. (since the installer insisted that I had a PPC processor).

Good luck. Hope you get it working.

And now I'm the one with the problem. I followed steps 1-9 above and had a "successful" install. But I'm failing to get it to work for Firefox 3.0.4 and Safari 3.1.2. My computer is an iMac with a 2.4 GHz Intel Core 2 Duo running Mac OS X 10.5.5.

(I'm trying to access http://all-access.cbssports.com/playe..., but this is similar to trouble I had months ago when I was trying to catch the Olympics.)

I was told "Installation is easy and will only take a moment..." but I wasn't so lucky.

A silverlight.plugin is sitting in my Library/Internet Plug-Ins, but it doesn't seem to be doing its job. Please assist if you can. Thanks.

Did you check to see if Safari recognizes the plug-in? Look under the HELP menu, for the INSTALLED PLUG-INS item and scroll through the list and see if Safari even lists the Silverlight plug-in, and check what version it sees as well. Make sure you have the 2.0 version installed. If it shows up, then I'm outta suggestions. I guess I would try to "uninstall" the plug-in and try again, but beyond that, I've got nothing. Good luck!

Thanks, Jeff. Safari is missing the plug-in in its installed list. Maybe my question becomes different: How do I get Safari--and Firefox, for that matter--to recognize the plug-in? A Mac newbie looking forward to learning how this thing works...

is there anyway to TRICK NetFLix into thinking that I am running of a Intel when in all actuality I am running off of a PowerPC?

My mac can handle the video stream.. I just know it.

when installing silverlight.2.0.dmg this mounts (there is an image of a paper with a hard drive on it) and then when I open this it opens to a folder with silverlight.2.0.pkg (which an image of a blank paper) when I click on this it opens to iphoto and downloads 12 silverlight images and then opens a window with a long list of files that were unable to open.

J. Gilley - Yes, go to Safari's prefs > Advanced and enable develop menu. Then in the menu go to Develop>User Agent>Safari 3.1 Mac.

The issue I am having is getting the SL2 plugin to be recognized by Safari. 1.0 yes, 2.0 no. I have even tried messing deep in the packages, I have gotten as far as "Thank you for installing silverlight, please restart your browser" in place of my movie. My hackds SL works on microsoft's site. All I want is Netflix on my ppc to combate planned obsolescence.

Ideas?

Any luck? I'm in the exact same boat and don't know anything about altering plugins...found workarounds for silverlight 2.0 on a PPC. Installed, but Safari isn't recognizing it. Trying to watch netflix (I have a PPC powerbook G4, and PS3....and am pissed that netflix supports neither!)

To manually install Silverlight on an Intel Mac: (This is what the techs at Microsoft ended up sending me: I think Silverlight should really include this in their faqs or something for all of us who are running into issues!)

===========

To manually install Silverlight please perform the steps outlined below: (Note: when completing these steps make sure you have quit our of all running Applications and that they have not just been minimized to the Dock)

1. Launch your web browser (FireFox/Safari) and visit Silverlight.net/GetStarted

2. On the lower right side of the screen you will see Install Silverlight, Choose Silverlight 2 Mac Runtime and allow this to download to your desktop. If the installation automatically launches quit out of it and complete the following steps.

3. Mount the Silverlight image that is on your desktop

4. Ctrl+Click Silverlight.2.0.pkg

5. Choose "Show Package Contents"

6. Open Contents

7. Copy Archive.pax.gz to Desktop

8. Ctrl+Click the Archive.pax.gz file that was placed on the Desktop

9. Choose "Open With", BOMArchiveHelper.app

10. This should extract a folder to the desktop called Library

11. Open this folder

12. Open the Internet Plug-ins folder

13. Copy Silverlight.plugin to Hard Drive: Library: Internet Plug-ins.

14. Restart your Mac

15. Visit Silverlight.net and go to Showcase, if you can view this page without being prompted to install Silverlight then it has installed successfully. Visit NetFlix to ensure that you are able to access their content.

If this is unsuccessful there may be an issue with your user account preventing Silverlight from working correctly. What we would like to do is test a new Mac user. To create a new Mac user:

1) Go to System Preferences

2) Go to Account

3) Choose the Plus sing in the lower left corner to open the new account window, enter Test for the user name, leave the password blank

4) Put checkmark in Allow User to Administer this computer

5) Choose Create Account

6) Now logout out of your original account and login to the Test account

7) Once in the Test Account visit Silverlight.net and go to Showcase, if you can view this page without being prompted to install Silverlight then it has installed successfully. Visit NetFlix to ensure that you are able to access their content.

If Silverlight works with the new Mac user you will need to contact Apple and have them determine why the original user will no longer allow Silverlight to work.

==========

Hope this helps you out: it sure helped me.

Maho22 -- actually the better instructions if your machine is in the state described by this post was already listed here: http://getsatisfaction.com/microsoft/....

Your instructions are a little more brute force :-)
