[L2Ork-dev] Won’t finish starting up

[Jeff Morris]

Hello everyone,

I’m experiencing an issue with Pd-L2Ork on in macOS (v. 14.6.1 on an M2 Max
processor). When I launch Pd-L2Ork, it seems to initialize, but it doesn’t
respond when I try to open a new patch, an existing patch, or the audio
test patch. I can open the Settings window, but all menu options are blank.
This happens now with the latest Pd-L2Ork version (20241014), but the
problem actually started Wednesday while using the previous version.

The console output shows the following:

Welcome to Pd-L2Ork
nw.js version 0.67.1
GUI is starting Pd...
User app directory found. Skipping copying of the Pd-L2Ork apps into the
user folder...
GUI listening on port 5400 on host 127.0.0.1
Pd started.
Incoming connection to GUI

and that’s all.

I monitored port 5400 with tcpdump, and I see Pd trying the TCP handshake
periodically and when I try to make a new patcher. It always reports a bad
checksum:

tcpdump: listening on lo0, link-type NULL (BSD loopback), snapshot length
524288 bytes
16:30:49.377467 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP
(6), length 64, bad cksum 0 (->3cb6)!)
    localhost.51182 > localhost.excerpt: Flags [S], cksum 0xfe34 (incorrect
-> 0xec3c), seq 350244288, win 65535, options [mss 16344,nop,wscale
6,nop,nop,TS val 611757691 ecr 0,sackOK,eol], length 0

But GPT said that was fine: "These messages are common when capturing
traffic on the loopback interface (lo0) in some OS environments like macOS.
This happens because checksum offloading is done in hardware (which isn’t
visible to the capturing tool like tcpdump), so the checksum appears
incorrect, but it doesn’t actually impact the functionality." What do you
think? So far, this is the only error message I can find. i didn't see
anything meanjngful in system console logs, but i didn't have much of an
idea what to seek there.

While troubleshooting, I completely removed the app and reinstalled the
latest version of Pd-L2Ork from the official site, I disabled System
Integrity Protection (SIP) using csrutil disable, and I made sure Pd-L2Ork
had Full Disk Access and added it to Input Monitoring. I also tried running
Pd-L2Ork without the GUI using -nogui, but it starts without errors and
shows no improvement.

I also tried downlaoding Purr Data today, but macOS said the application
file was damaged and couldn't be opened (this didn't look like the usual
security cincern with downloaded programs), and I tried downloading it
twice.

Any help or advice would be greatly appreciated!

Thanks,

𐌌
