I have just installed POP_OS on my macbook pro and I installed the drivers for the wireless card but I have no networks showing in the windows. Is there any there type of drives that i'm missing or doest it have to do with pop_os because if i install ubuntu bridge I can get the wireless to work but when i try in POP_OS the networks don't show up.

Welcome to LinuxQuestions.org. I know nothing about POP_OS (and had to get an overview from Google), but to start with can you use the lspci command in a terminal to confirm that wireless drivers are loaded?
*You might need to enter the full path of the command. Just post the section that pertains to your wireless network device if possible.

If inxi is installed, then the following will yield network card info
Do wireless device nodes exist? Post output here if you're not sure.
It might also pay to check that the wifi is not soft-blocked (disabled). For that the 'rfkill' utility is needed. Hopefully that is installed already. If not, you may need to get wired internet access first.

I assume that NetworkManager is installed with this OS. (A review I just read suggested that this is the case.)
