how to uninstall after a 32 bit app when you already upgraded to a 64 bit OS?

Hi bhambill2,

You can also download a free application called Go64 which scans your Mac for all 32 bit applications. It will provide a way to upgrade to the 64-bit version. There is also an option to delete the 32-bit app as well if you don't use the particular application often.

I hope this helps.

Ideally, go to the App store (or vendor's site) and upgrade it.

Generally, go into Applications and delete it. You can also do this via Launchpad if you like
