I got the program monolingual for my intel machine. It removes unnecessary language files. It also has the feature to remove PPC architectures. Now that does this mean? And on the FAQs I found this: Q. Should I remove the non-Intel architectures on my Intel based Mac? A. You can use Monolingual to remove non-Intel architectures for your installed applications (even if some of the applications are PowerPC-only; Monolingual is smart enough not to remove PPC forks if those are the only ones in the universal binary). However, you should not strip the System frameworks if you want to use Rosetta. Rosetta needs the PowerPC code for all frameworks used by the emulated application and if it can't find it, you may see messages such as the following in the console: /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa: mach-o, but wrong architecture Now what does all this mean? What will happen if I remove all these architectures? Will my computer stop working?
