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.
