Ok, well you don' t need to run special software. You just need to use a non-optimized VM The *worst* case is turn 32bit mode on, and use Rosetta I've put a non-optimized VM in the experimental folder/COCOA via http://smalltalkconsulting.com/squeak.html called Squeak V5 SLOW VERSION FOR TESTING DO NOT USE FOR GENERAL USE.app.zip That gives you something that is like 8 or 10 times slower than normal.

Re: [Pharo-project] [update] #10500

Ok, well I've not compiled the freetype plugin for V5.x yet, so whatever is happening it's not using freetype. Someone will need to decide if the bitblt override plugin should be part of the base system? There seems to be lots of confusion about what smalltalk software, which VM version, and if it's using an override BitBlt plugin. Maybe someone can detail the choices and decide which is the most optimum for Pharo. For testing purposes I *believe* you can run the V5.0 VM on powerpc, or on MacIntel set use 32bit mode in get info. Then included the plugins as shipped with the 4.2.2 VM. You still might need to confirm the 32bit FreeType plugin gets loaded. The V5.0 Vm has the latest bitblt changes from VMMaker, but that might be different than the ones in the older BitBlt override.

It seems that with your setup the FreeType fonts are rendered without subpixel AA. I use the Mac VM, I think with the extra BitBlt plugin, and they look better.
