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

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.

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

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.

�� 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,

I don't know yet Jeff. I don't have either a macos sierra at hand. Once
a Mac OS Sierra user reported me the problem your are mentioning[1], but
I did not get very far investigating the problem.

For me it is not clear at all from[2] if there is any Mac VM 4.0. May be
Esteban can enlighten us.
