OS = macOS Sierra Version 10.12.6 I have encountered the same behaviour for Pharo 6.0 and 6.1 64 bit or 32 bit, it doesn't matter. Workflow: Downloaded Pharo6.1-mac.zip and placed the resulting .app file into the normal Applications folder (a hit on the Pharo website recommends this for Sierra)
Started it from there and of course loads the included pristine image. Because of my 4k screen the first thing that I did is change fonts to "large" via System menu and then maximize the window by clicking the little green icon in the top left corner. Repeated this procedure several times (reinstalling etc.) sometimes it froze instantly, sometimes after redrawing attempts, sometimes it still runs and I can manually "repaint" the window by swiping a playground window everywhere. at times it works ok but then suddenly freezes after a few minutes or so e.g. when I save a method. So, to me it is unpredictable. At times I've tried CTLR + "." sometimes it reacts but then freezes again.. After that I've removed 6.1 64 bit version completely and reinstalled it, this tim enot in the Applications folder but in another folder on the Desktop, alas, to no avail, also for the 32 bit version of Pharo 6.1. Officially Apple does not support UHD 4k screens on a Mac Mini from late 2012 with Intel HD graphics 4000. However, like almost everybody else who uses 4K screens on this computer, I am using the SwitchResX app which tells macOS about this resolution, adjusting the parameters it is native 3840 x 2160 @ 30 Hz refresh rate. Apart from some graphical glitches on the start up screen graphics are perfect with all the apps I use, also for graphically intense apps like Affinity Photo and Affinity Designer and even 4K videos. If you are still using the same graphical interfacing in 6.x as in Pharo 5.0 this shouldn't be the problem, i think.? Nevertheless, yes. I will try with a a lower non-native resolution later and let you know if that made any difference. Pharo 5.0 is completely stable and works flawlessly, with the image with Seaside and Wooden (GL) loaded. No crashes at all. really is great. I am reviving my Smalltalk (my favorite programming system), because I prefer to write apps for mac, linux and Windows with it. mostly as (local) webbrowser apps, with some Morphs put in it. This allows much faster developing and does not cause headaches :o) I am also writing iOS apps (e.g.RavelNotes for iOS iPad and Apple TV (lots of time, retired in 2016) but this has to be done with Xcode and Swift, with has increasingly complexity, which is inherent to statically typed languages. (like generics, protocols.etc.) No way (yet) to do this with Smalltalk, also for 3D apps e.g. with SceneKit it's still not fast enough, which leaves me no choice. Thank you, kind Regards. Ted. (I was also here in 2012, but was under tons of IT stress, which reflected in my writing and responding, luckily this is gone) -- View this message in context: http://forum.world.st/Pharo-6-0-and-6-1-64-bit-freeze-on-MacMini-tp4957969p4958166.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
