In Sophie I guess you used the extended clipboard exclusively, but for Squeak it's not quite as clear-cut ...

I tried both with AbiWord and TextEdit, and all I get is a String (without font styles, alignment or color). I also tried to paste a graphic (created with the Grab app) and I also failed (I get the previous String clipboard).

Ah, I misremembered. Neither RTF nor TIFF reading is implemented. On Unix we get text/html as rich-text format, and that works. Now I remember something about a RichText Squeak reader somewhere, but can't place it ...
Bitmap pasting works only if the format is PNG or JPG, which a lot of apps produce, but not all, apparently. For screenshots I use shift-control-command-4 which puts a PNG into the clipboard and that can be pasted fine.
HTH,
