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
