Change Google Chrome cache size on OS X
You would have to launch it from the command line with the following flag --disk-cache-size=524288000
, where 524288000
is the upper limit of what it could be set to.
You could try to make a script that launches it with the augment.
Something like:
#!/bin/sh
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --disk-cache-size=524288000 &
Then name it with a .sh
extension, and chmod u+x /path/to/file.sh
and you should be good.
