Hi, I have tried Pharo64 on macOS. It is not possible to open it from Finder by dragging .image file and dropping it on Pharo.app. Dock shows Pharo icon but it immediately closes without any error message. I can open it using ./Pharo.app/Contents/MacOS/Pharo ./Pharo64-60432.image Then I have loaded Iceberg and it works. Loading another project using Iceberg does not work because of missing libgit2 library. Spotter search input is white, but it may not related to 64bit version. Thanks for the 64bit effort :-) Juraj -=-=-=- Image ----- /Users/jura/Downloads/pharo-64/Pharo64-60432.image Pharo6.0 Latest update: #60432 Unnamed Virtual Machine --------------- /Users/jura/Downloads/pharo-64/./Pharo.app/Contents/MacOS/Pharo CoInterpreter * VMMaker.oscog-eem.2143 uuid: fe064b6b-e530-4766-837d-799ffe1e8dcd Mar 3 2017 StackToRegisterMappingCogit * VMMaker.oscog-eem.2143 uuid: fe064b6b-e530-4766-837d-799ffe1e8dcd Mar 3 2017 VM: 201703031554 https://github.com/pharo-project/pharo-vm.git $ Date: Fri Mar 3 16:54:16 2017 +0100 $ Plugins: 201703031554 https://github.com/pharo-project/pharo-vm.git $ Mac OS X built on Mar 3 2017 23:52:26 UTC Compiler: 4.2.1 Compatible Apple LLVM 7.3.0 (clang-703.0.31) VMMaker versionString VM: 201703031554 https://github.com/pharo-project/pharo-vm.git $ Date: Fri Mar 3 16:54:16 2017 +0100 $ Plugins: 201703031554 https://github.com/pharo-project/pharo-vm.git $ CoInterpreter * VMMaker.oscog-eem.2143 uuid: fe064b6b-e530-4766-837d-799ffe1e8dcd Mar 3 2017 StackToRegisterMappingCogit * VMMaker.oscog-eem.2143 uuid: fe064b6b-e530-4766-837d-799ffe1e8dcd Mar 3 2017 -=-=-=-=-
