Lumin App Not Opening on Mac

  • L1 serves as a USB drive, not a network file server. It only appears on the computer if you connect a USB cable from the computer to the L1.
  • If the L1 is in NTFS format, Mac needs additional software to be able to read it
  • If the computer should be capable of reading the file system, try doing a file system scan and repair on the computer (do it from Windows if in NTFS format). Alternatively, re-format the L1.
  • If Lumin app cannot see U2 Mini on the network, disable computer firewall, and grant all network permissions especially Local Network to the Lumin app
 
Hi Wklie, thank you so much for the quick reply!
My L1 is connected to a Mac mini via USB cable, and yet the Mac mini doesn't recognize the Lumin L1!

Lumin L1 is formatted in FAT 32

I released the permissions in the firewall, but it didn't connect!

Maybe it's a problem with Apple M computers, because when I connect the Lumin L1 (USB cable) to an old Macbook (Catalina) it works perfectly!
 
On my M2 MacBook Air, the computer asks permission to access the "accessory" (the L1). Then it shows up on the desktop. But look in the sidebar of the finder as well in the event your Apple device is behaving differently. Also, this may be obvious but double check the L1 is connected to power when you connect it to your Apple device.

If it still does not work with permissions granted, try to do a Scan and Repair using a computer. Or format it again. Here's the procedure to restore the factory format:

Thread 'Lumin L1 with 4TB or 5TB HDD'

Before reading further, please understand that replacing any component inside the L1 may void the warranty. Lumin cannot assure the correct functioning of L1 if not used with the original HDD. Any L1 to be shipped back for warranty repair purpose must contain the original HDD.

The below information is FYI, and I cannot recommend any user to replace the HDD by themselves.

I've investigated the requests of changing the L1 HDD to something larger such as 4TB or 5TB HDD.

Previously I've said that Lumin L1 is limited to 10mm thick HDD. Turns out this limitation only applied to the very...
