[carlosperate]

In macOS 10.12 Sierra, 10.13 High Sierra and 10.14 Mojave, Mu is able to correctly create the virtualenv with dependencies, but when trying to run a pygame zero script it throws the following error in the console/repl panel:

Going back to pygame version 2.1.2 works, and v2.1.3 and newer fails.

In macOS 10.14 Mojave:

• pygame v2.1.3 and newer cannot find libmp3lame or libomp in older macOS versions pygame/pygame#3941

I also have issues in 10.15 Catalina, but that might be related to running Mu in a macOS VM.

• Error when running code: No hardware accelerated renderers available pygame/pygame#3835 (comment)

Hey hey.

Is this whilst using vmware?

Also I wonder what the mac model is?
(wondering if it is CPU instruction related)

[carlosperate]

Hi René! Yes, this is using virtualised Intel macOS with VMware using an i7 Macbook Pro 2020.
Unfortunately I don't have any mac with macOS lower than 12 Monterey, so tests in older macOS versions are done with virtual machines.

[illume]

Hey hey.

pygame==2.5.1 fixes this issue.

At least it does work on the 10.11, 10.12, and 10.13 tested on.

Hopefully it works for you too?
