Older Pharo on MacOS Sierra

Hi,

Pharo 4 might be hard on MacOS Sierra.

There was a late change to the VM, at least for Squeak, to stop the black screen on startup on Sierra.    Pharo 4 was before that change, and, for that matter, before Sierra.  Pharo 5 was after and clearly has that change.

I'm pretty sure that the patches are one of these two:

https://github.com/OpenSmalltalk/opensmalltalk-vm/...


https://github.com/OpenSmalltalk/opensmalltalk-vm/...


and I'm almost 100% sure that the second is the magic one.


The simple solution would be to replace the VM in the Pharo 4 bundle with the VM in the Pharo 5 bundle, but, alas, the VM in the Pharo 5 bundle can't read the image from Pharo 4.

So it would look as if one's choices are:

* Build the version of the VM from the Pharo 4 bundle, but, apply one or both of the patches above.
* Figure out why Pharo 4 is necessary and move to Pharo 5.
* Run a squeak V3 VM and hack something together.  This might not give the full Pharo experience.

To run the squeak V3 do the following:

Download and unzip the newest Squeak V3 VM.

https://bintray.com/opensmalltalk/vm/download_file...

Alt click on the CocoaFast app and choose open.
Quit.

Download Pharo 4.  Alt click on Pharo 4 and choose "Show Package Contents."  Navigate to Contents -> Resources.  Drag the "Pharo4.0.image" overtop the CocoaFast app and it launches.  You do have startup errors, so, you now have some time to play around.

I realize that neither look so easy, though the second one is probably the wisest just because the Pharo group moves quickly.

Hi,

Thanks, that's very nice.

There is also a mac build here:

http://files.pharo.org/platform/

and the pharo 4 one does not work.  That's the one I found when I poked around and tested it.

cheers

I updated the VM on Pharo 4 to work also on Sierra, so this does not remains true :)

no, it will not work, because Pharo 5 is spur and Pharo 4 is not

… or you can download the Pharo 4.0 VM (from here: http://files.pharo.org/get-files/40/) and run your Pharo 4.0 and Pharo 3.0 app without problems (I didn’t try Pharo 2.0 and 1.4, but I do not see why they wouldn’t work). 

now, Pharo 1.0 will not work I think, because it is not a Stack image (it didn’t existed at the time)… there yes, you will need one of the legacy VMs that we do not maintain anymore… for that, there are some VMs around, but I frankly would migrate any 1.0 based image… is work (and maybe hard work), but at the end it will pay :)

if what you have is a OneClick package, the best approach is to extract your Pharo*.image, Pharo*.changes and Pharo*.sources and then use the Pharo 4.0 VM with them,
