So I installed steam today on playonmac and when I tried to log into my account, it says I needed to verify it was me through a code sent to my email. But after like 5 times of resending the email, I don't get any... Is their a fix for this or am I screwed? I checked if it was in my spam folder and nothing. And I know this works because I recently linked my dads computer to my account doing the same process and it worked.
Try to install the Linux version of Steam on your computer first, and then try to run the playonmac version again. I just did it on my linux machine the other day, and it asked me to do the same thing, so I did that, and it worked. Maybe that will help.
