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.

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 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
