Hi David, I do not think I can help, maybe someone with Big Sur can take a look? I am on Linux. I did a fresh download of Pharo 8 and loaded OSProcess, and I cannot reproduce the problem on my system. Dave On Fri, Feb 04, 2022 at 03:54:57PM +0000, Davide Varvello via Pharo-users wrote:
Hi David,I don't think is an issue of warning, even if I apply your patch I have the same error, see: https://imgur.com/a/pYcLLWx
To reproduce the bug:??Be on ??Big Sur 11.6.3 (20G415) https://support.apple.com/en-us/HT213055Download Pharo 8: curl https://get.pharo.org/64/80+vm|bash Open the image and evaluate ina playground:Metacello new???? ?? configuration: 'OSProcess';???? ?? repository: 'http://www.squeaksource.com/MetacelloRepository';?? ?? load .
and then (PipeableOSProcess command: 'ps') ??output.
The bug will show itself CheersDavide On Friday, February 4, 2022, 04:39:28 PM GMT+1, David T. Lewis <lewis@mail.msen.com> wrote:
Hi Davide,
Actually the warning has been removed in newer versions of OSProcess. I do not have time to do an update for Pharo now, but in the mean time you can apply this change in your image to remove the notifier:

Hi guys, Suddenly evaluating a simple: (PipeableOSProcess command: 'ps') output, or any other PipeableOSProcess command, Pharo gives me: "aio event forwarding not supported". I guess it is something related to the latest update of the OS, specifically Big Sur 11.6.3 (20G415) https://support.apple.com/en-us/HT213055I'm on a Mac, of course, Pharo 8.0.0, Build information: Pharo-8.0.0+build.1128.sha.9f6475d88dda7d83acdeeda794df35d304cf620d (64 Bit) Can you help me, please?CheersDavide
Hi Davide,
The warning message indicates that the AioPlugin is not present in your VM. I do not know the reason for that, although your PipeableOSProcess should still work if you proceed through the warning.
