Can you still make QuickTime to store temporary recordings on another drive? I need to get QuickTime Player to store its temporary files on another disk. I found an answer here, which I tried, but QuickTime Player quits with an error when I try to make a Screen Recording. I used:

$ cd ~/Library/Containers/com.apple.QuickTimePlayerX
$ mv Data Data.bak
$ ln -s /Volumes/'Keeper 4'/QuicktimeScratch QTData
$ ln -s QTData Data


Does this no longer work, or did I screw something up? Keeper 4 is an external HD. I tried it with and without an existing QuicktimeScratch directory.
It seems that Apple doesn't want you to do this for whatever reason, so they prevent the symbolic link hack from working at the level of the Data/ subdirectory. After fooling around with this, I found a workable solution one level up:

$ cd ~/Library/Containers/
$ mv com.apple.QuickTimePlayerX/ com.apple.QuickTimePlayerX.backup/
$ ln -s /Volumes/&lt;NAME_OF_VOLUME&gt;/com.apple.QuickTimePlayerX/ .


No need for a double link trick this time around.
