Upgraded from V5.1.7.10514 to CrealityPrint V7.0.1.4214 and trying to “send print” to printer comes up with “ Upload failed (7)” error which is a Wiki says its a Mac OS error.

Wiki says:

“The macOS Privacy & Security settings prevent the slicing software from accessing the local network, making it unable to communicate with the printer on the LAN.

Solutions: You need to grant local network access permission to the slicing software in the system settings:

1. Open “System Settings” → “Privacy & Security” → “Local Network”.

2. Find the Creality Print software you use in the application list, toggle on the permission switch, and allow access.”
i’ve done all that but still no luck.

Both versions of Crealityprint can see the printer under “Device heading”, also camera showing working print see by both versions.

Thanks

Dose the symbol of the printer appear in left bottom corner after you press send print, sometimes it takes 30 seconds

Yes the symbol does appear.
I can upload and start a print using an earlier version of Creality print and then go back to the new version (that wont upload) but it shows the printer moving in the video feed so its obvious connected to the printer.

One thing I noted is that the Laptop is on the 6GHz network band while the printer is on the 5GHz band. But then why does the old version work? I also managed to force the Laptop to use 5GHz and the problem is still there.
