4K UHD Backup on Mac

[seppBalboa]

Hi there,

I would like to back up my 4K Discs. I got a UHD friendly drive. I can open the disc but cant decrypt the BD.
makeMKV says: Failed to open Disc.

where do I put the keys (keydb.cfg) on the Mac so makeMKV can use them. Internet connection is enabled in the settings but cant find a proxy server for that.

thank you for your help.

Your MakeMKV data directory, set in Preferences->General.

However, there should be no need for that, if you can access internet and do not have something blocking access to the automatic downloading of keys.The key database you can manually download elsewhere will pretty much always be behind MakeMKV's automatic key database.
