So I gave my 6yr old the old 12" G4 Powerbook she of course like to play facebook games. Is there a good way to make that happen reasonably smoothly?
I think it's possible, depending on the version of OS X you plan to use. It will be a smoother experience if the G4 is running on OS X.4 Tiger. I'm currently running OS X.5 Leopard on a 1.25 GHz G4 Mac Mini as a HTPC and it has some trouble with some flash websites and streaming 480p content from Hulu and etc.
But I think the biggest problem will be Adobe Flash. The latest version for PPC Macintoshes is 10.1 and it's slow. You could run Flash version 9.x, but you may run into some snags about games wanting you to use version 10.x or higher. Also, think about security since Adobe no longer offers updated versions for PPC. With your 6 year old on Facebook, she may click on a spammy link that may lead to old Flash exploits. It's a small possibility, but something to think about.
Honestly, best thing is to run Firefox with some plugins that disable ads (including facebook ads) and a flash blocker that white lists facebook.com
Hope this helps and that someone better suited chimes in.
Camino helps..
Where can I buy Tiger? it's on Leopard now
Ah, yes! I completely forgot about Camino. I think it has a built-in ad/flash blocker too, if I remember correctly.
As for getting Tiger, I'm not sure where you could find copies in Germany. I would definitely check eBay or Amazon.
By the way, is the PowerBook slow with Leopard and Facebook games right now? Have you tried doing a reformat and installation of Leopard to see if a new installation speeds things up?
I strongly recommend going back to Tiger and then installing either Camino or TenFourFox optimized for PPC G4. The memory footprints on these PPC optimized versions are smaller compared to Safari on Leopard and they would run snappier.
The greatest and the fastest 12" G4 is the 1.5GHz model which will only have up to 1.25GHz of RAM. It is recommended to have more than 1GHz of RAM to run Leopard flawlessly, 1.25GHz barely goes over that. While on Tiger that amount of RAM is more than enough.
