I wanna copy and paste videos and musics, but how?
I used an app called "Android file Transfer" for my Galaxy Nexus that worked well
This is the main drawback with the Note II/S3.
See here for what I've found out so far about alternatives and work-arounds: https://forums.macrumors.com/threads/1468070/
(Feel free to add any alternative solutions you discover).
Possibly the simplest solution is to get a Micro-SD card and suitable reader (MacBooks with a SD card slot just need a Micro-SD-to-SD adapter which you can usually get thrown in with the card).
No, That doesn't work on Samsung phones - it's not clear whether it is Samsung or Google who have broken it.
And before anybody suggests it, the 'USB Disc Mode' on older Androids has also been removed from ICS and later (that is Google, I think).

AFT worked on my Note 2. Just plug it in, opened it on my laptop, and dragged and dropped my music. Simple as that. Check out Keis over WiFi (comes preinstalled on Note 2), its a wireless file transfer alternative to AFT, however I had a really easy time with the AFT.
AirDroid is a good way to move files and if you have it installed on your phone then you can use any browser on computers to transfer files to and from your phone.

Interesting - just tried it on my Snow Leopard work machine and it seems to work OK.
Interesting - just tried it on my Snow Leopard work machine and it seems to work OK. Previously I'd tried it on Lion/Mountain Lion - so it may be a Lion/Mountain Lion issue or it may be that Google have fixed it (unfortunately, Google don't give any release notes or version history on the download site, but the version I've just downloaded is timestamped Oct 15 - after I tried it).
Eureka - problem identified: Uninstalled Samsung Kies and Android File Transfer springs into life. Seems you can't have both.
You mean uninstall Kies from your phone? I have Kies installed on my phone and AFT worked.
No - uninstall the Kies software from your Mac (using the uninstall program that comes with the Kies download).
If you've never downloaded and installed Kies on the Mac, you may not be affected.
