First, great work and thanks to all contributors. Using macOS Big Sur version 11.4 on MacBook Air 2019...
1. In a new sub-directory "pharo9" (I was using a pharo8 directory, so pharo9 is to keep things separate). In pharo9, I used "curl -L https://get.pharo.org/64/ | bash" to get the latest release. Then I ran ./pharo-ui to start Pharo. Very strangely, it was able to present my pharo8 images to choose for opening. I quit without choosing any image, then went looking to find out how it was able to find the settings. In the course of that, I realized the default download had got me the 8.0 release. 2. Then I used "curl https://get.pharo.org/90+wm | bash". The image came up with a strange looking dialog across the top that indicated freetype font lib's could not be loaded. I just proceeded and was able to navigate somewhat. The Settings for fonts were completely absent. I kept browsing, but more freetype font problems kept appearing. 3. I then compared the dylib's in the pharo-vm (what I had in pharo8) vs. what I just got in pharo9 - very different lists. I copied the libfreetype.6.dylib, libfreetype.dylib, and libFT2Plugin.dylib files to the new vm, and then the Pharo9 image came up nicely. 4. I thought I was home free, and continued browsing. I happened to look at the Pillar-Core code, and I got "Cannot locate libcairo.2.dylib". Browsing a few other places did not show this problem. That's it for now. I will try a bit more later, but I'm going back to Pharo8 for today. Yanni Chiu
