I've push the latest cocoa based 32/64bit & 64/64bit macintel/powerpc VM 5.4b1 This includes the logic for the microsecond clock, to call the clock the change set is attached. I've also built the 64/64bit VM for Intel that works with 64bit squeak images. Look for the folder experimental/64bits in the regular places found via http://smalltalkconsulting.com/squeak.html or ftp://ftp.smalltalkconsulting.com/experimental/64bit/ or http://homepage.mac.com/johnmci/FileSharing.html click to experimental, 64bits In a sub folder the file names are: Squeak 64-32 5.4b1.app.zip or Squeak 64-64 5.4b1.app.zip This *beta* VM runs in 32 or 64 bit mode on macIntel, and 32bit mode on powerpc to support Squeak 32bit images. Includes the freetype plugin, and requires os-x 10.5 or higher. The *beta* 64/64 VM runs only in 64 bit mode on macIntel to support Squeak 64bit images. It does not include FreeType at this time, and it requires os-x 10.5 or higher. -- =========================================================================== John M.
