IMac PC does not support latest Adobe FP/can't watch Youtube/Only solution=new computer??

Question

I can no longer watch You Tube because the latest version of Adobe Flash Player
will not download to a PPC. I run Tiger 10.4.11 (I know that's ancient but it works
very well!) Does this mean the only way to view You Tube would be to buy a new
computer? Everything runs perfectly except You Tube. I've never been a big fan of the site
I still would like to have access to it but buying a new computer to get one site seems
like a bridge too far. I have Adobe flash Player and but not the latest version.
This problem only happened recently which seems strange. I even have a
couple of videos on the site and have access to my account. I can get the site and my account but
first the sound stopped playing a month or two ago but the videos still played. Now the videos
don't play at all. From what I've heard, only a computer with Intel can accept the latest version of
Adobe. Any thoughts or tips??

Answer 1

It will work on a PPC Mac running Leopard, but not Tiger:
I am in the same boat. I run a G5 PPC iMac and I cannot watch flash videos on the BBC website or on BBC iPlayer, and it struggles on YouTube.
For reasons that passeth all understanding, they all work with the PPC version of Firefox, called TenFourFoxG5.app, once you have enabled plug-ins, as it does not natively support Flash.
You can download TenFourFoxG5 from here:
http://www.floodgap.com/software/tenfourfox/
Now for the interesting bit: TenFourFox, like Firefox, does not support most plug-ins. Unless you are prone to headaches (in which case don't) you can read about that here:
http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported
But there is a workaround!
Open TenFourFox and type in the address bar: about:config (no spaces) and click return. This gives you a warning that it might harm the application. Ignore that and click on 'I'll be careful, I promise' and you get the config file that you can edit - with great care.
Look/search (scroll down) for: tenfourfox.plugins.enabled
Set it to true. (Double click it to toggle it)
Now close TenFourFox, open it again, and Flash will now work, as it now uses the plug-ins that Safari has stored.
I am using Flash 11.5.502.55 in TenFourFox and it works just fine. Here is how to get a working version of Flash Player:
You can check here:  http://www.adobe.com/products/flash/about/  to see which version you should install for your Mac and OS. Note that version 10,1,102,64 is the last version available to PPC Mac users*.
* Unhelpfully, if you want the last version for PPC (G4 or G5) Macs, you need to go here:  http://kb2.adobe.com/cps/142/tn_14266.html  and scroll down to 'Archived Versions/Older Archives'. Flash Player 10.1.102.64 is the one you download. More information here:  http://kb2.adobe.com/cps/838/cpsid_83808.html
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/909/cpsid_90906.html
and also that you follow the instructions closely, such as closing ALL applications (including Safari) first before installing. You must also carry out a permission repair after installing anything from Adobe.
After installing, reboot your Mac and relaunch Safari, then in Safari Preferences/Security enable ‘Allow Plugins’.
(If you are running a PPC Mac with Flash Player 10.1.102.64 and are having problems with watching videos on FaceBook or other sites, try the following solution which fools the site into thinking that you are running the version 11.5.502.55:)
Download this http://scriptogr.am/nordkril/post/adobe-flash-11.5-for-powerpc to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work.
