My bank has an online deposit feature, but it tells me that I have to run 32 bit Java in order to use the function. How do I force Safari to run 32 bit?
iMac, OS X Yosemite (10.10.3)
you can't
you can use a virtual machine to run a 32bit operating system though
virtual box is a free virtual machine
you can likely find a linux 32bit distribution and handle it from a browser on it
or you can take contact to your bank and ask for they advice
Probably doesn't help, because the feature is not available in OS X 10.10 Yosemite (and likely not in 10.9 Mavericks either - though I have no way to check quickly) but if your computer can run OS X 10.8 Mountain Lion or older, Safari 6.2.6 and earlier releases for older versions of OS X have the option of opening Safari in 32-bit mode.
Of course that 32-bit mode may introduce other browser incompatibilities, and re-introduce other browser vulnerabilities presumably patched in newer versions of Safari.
If you can find a copy of Safari 7.0.6 it will launch in 32 bit mode with 10.10.3.
Also the latest Firefox browser, 38.0.1, will launch in 32 bit mode:
