Could you please describe in step by step detail. Hi Ralph! I think the best way to understand why Morphic is revolutionary is to read the papers of its creators (e.g. http://web.media.mit.edu/~jmaloney/papers/DirectnessAndLivenessInMorphic.pdf) I also wrote http://stackoverflow.com/a/4410189/424245 which should give a taste and also answers your question more directly.

Quite useful I'd say ;-) [image: Inline image 1] The rotation halo might be only for fun, but many of the others are really useful, allowing you to move, delete, inspect, take an image, copy, etc, etc, etc. -- best, Eliot

I'm running Squeak 4.0 but I assume my question still applies. If not, other Pharo users might want to know. I am not in the habit of using halos, not really sure what they are for. But your description implies they are quite useful. What does "bring up halos on and inspect a button to see how to duplicate > its action" mean? Could you please describe in step by step detail.

Re: [Pharo-dev] pharo works fine on yosemite

Just upgrade to Yosemite, Pharo seems to work fine so far. As usually it does not full screen properly with the new green window icon, but it does fullscreen properly when fullscreen is chosen at pharo settings. Unfortunately installing Yosemite has not been a smooth ride. My late 2013 iMac got stuck to "About a minute remaining" for over 40 minutes and from what I have read here http://osxdaily.com/2014/10/17/os-x-yosemite-installation-stuck/ Some got stuck to this stage for up to 72 hours (WTF). Apparently from firing up the console (CMD+L) even though the installation appears to finish on time it takes extra time to move back your files which may explain the long time. I have even seen smoke get out of my iMac ( o_O ) during reboot, or maybe it was dust because the fans got crazy-speed (o_O) , first time it happened to me. So I cant recommend upgrading. Anyway everything seems to work fine now, Yosimite is slow to boot (around 50 seconds but I dont have a flash drive) but overall it looks like it works fine.
