'Rekordbox doesn't want to start exporting, I have a USB in my computer but it doesn't give me the option to export in the right-click dropdown menu to export my files or playlists to the device.'
If Rekordbox does not show you the option to eport to a device, rekordbox cannot find any suiteable devices to export to. Sometimes it happens that Pioneer DJs Rekordbox (music management software) looses connection to your USB or SD device. This can be cause by a lot of things and is mostly out of your control.
By now you should be able to export again to your device. If above doesn't solve it, you got something else going on.
tja je moet er maar tegenaan lopen
OSX users that have issues after updating to Catalina or higher.
The issue why you cannot export tracks to a Device might be because of some of your security settings as OSX has introduced more user control over connected devices.
By default it might be so that no program gets right to write or have access to a external device, this needs to be allowed by the user for each program.
Check both of them and make sure that you have rekordbox on the right, if not add it by hitting that little + icon
If you can set a mark in a checkbox before the entry, make sure to do so.
Restart rekordbox (6 is the current version, but this also applies to older versions), or your computer and there you go
The security issue I mentioned in the previous posting keep occurring to people if I need to believe all the phonecalls I keep getting about it.
As a reminder see my previous posting and check your security settings when Rekordbox does not see devices you want to export to.
I mentioned Catalina or higher, so that would also include : OSX Catalina, OSX Big Sur and OSX Monterey (and probably also future version that are not yet released )
BTW, properly formatting your device and export the track again might also help you, this sorts out different issues.
