Hi Phil,

Thanks for your message. I��m afraid I don��t have a perfect solution at the moment, but I can share what I��ve observed:

- The latest PharoLauncher 3.4.1 seems to have an issue: it hangs immediately on startup, both on Sequoia (your environment) and Tahoe (my environment).

- PharoLauncher 3.2-2024.05.24 starts up, but trying to launch a Pharo 12.0 image produces a PhLTranslatedModeWarning and fails to open (tested on Tahoe).

- Selecting a Pharo 13.0 image with 3.2-2024.05.24 works (tested on Tahoe).

So unfortunately, the ��general solutions�� I mentioned earlier don��t really help in the current situation. I wish I could offer a clearer fix, but for now this is all I��ve observed.

Sorry I can��t be more helpful at the moment!

Best, Masaya

Hi Masaya,

Many thanks for your message. I��ve gone through the steps you suggest, but I still have problems.
Here��s what happened with each of your numbered steps:
(1) Curl returned ��HTTP/1.1 200 OK��. I assume version 1.1 is ok. I was able to access files.pharo.org ok.
(2) When I looked for the PharoLauncher file in /Library/Application Support, no file was there. I tried launching PharoLauncher again, but still no file.
(3) This wasn��t relevant as PharoLauncher never reached a state where I could select an image file.
(4) I set the firewall to allow PharoLauncher to accept connections.
(5) I was able to execute using the ��arch -arm64�� command. Same result as before.
(6) Launching from a command line generated no errors. The application just hangs. I��ve attached a screen dump of the PharoLauncher window.

I hope you can help!
Thanks, Phil

Hi Phil,

I understand you��re having trouble with PharoLauncher on your M3 MacBook Air, hanging when trying to connect to files.pharo.org. Here are several steps that usually help resolve this issue:

1. Check your network connection
Open Terminal and run:
curl -I https://files.pharo.org

   �� If it returns HTTP/2 200, the connection is fine.
   �� If it fails, try switching Wi-Fi networks or disconnecting from VPN.
   �� Also check that you can open https://files.pharo.org in your browser.

2. Clear PharoLauncher cache
Old settings or caches can cause the launcher to hang:
mv ~/Library/Application\ Support/PharoLauncher ~/Library/Application\ Support/PharoLauncher.bak

Then restart PharoLauncher. It will create fresh settings.

3. Manually download a Pharo image
   �� Go to https://files.pharo.org and download the image you need (e.g., Pharo 10 latest stable).
   �� Unzip the .zip file, which will contain a .image and .changes file.
   �� In PharoLauncher, use Add Local Image to select the .image file and start it.

4. Check macOS security & firewall
   �� Go to System Settings �� Network �� Firewall.
   �� Make sure PharoLauncher is allowed to connect.
   �� If using Intel (x86) binaries on Apple Silicon, consider using the native ARM64 version.

5. Apple Silicon specific note
   �� Make sure you downloaded the ARM64 version of PharoLauncher for your M3 Mac.
   �� You can test by launching from Terminal:
arch -arm64 /Applications/PharoLauncher.app/Contents/MacOS/PharoLauncher

6. Debugging
Launch PharoLauncher from Terminal to see logs and connection errors:
/Applications/PharoLauncher.app/Contents/MacOS/PharoLauncher

If network issues persist, manually downloading the image and using the local image option is a reliable workaround.
I hope this helps! Let me know if you run into any further issues.

Best regards,
Masaya

Hi

I��m having trouble reinstalling PharoLauncher on an M3 MacBook Air running Sequoia 15.6.1.

I uninstalled a working version of PharoLauncher (long story) and then downloaded and installed a new version. On launch, a Pharo window opens and then it hangs trying to connect to ��files.pharo.org��.

I��d be grateful for any help.

Phil
