I have tried to delete app store preferences and restart but it didn't help. I ran disk utility and it does not find any issues.
I have also tried to reinstall 10.13.3, that fixes it but as soon as I update to 10.13.4 it happens again. I tried a third time by logging out from the app store while on 10.13.3 and then updating to 10.13.4 but I got the same results. This is on my macbook pro 2016. I also installed 10.13.4 in one of my iMacs, no problem there.
Any suggestions? Thanks in advance.
It worked for me ! Thank you !!!
Fixed for me in 17E160e.
I have this issue only after 17E150g and the terninal command doesn't seem to bring up the beta 3 160 version. I have tried all the suggestions and still doesn't work. This is a really bad bug. Any other suggestions to try?
Oddly I cycled Little Snitch on and off and the app store function came back on. Still can't see the last beta of today though.
Funny how most of my email security certs had been modified. Cleared them all and App Store works.
Anyone have a clue as to how these cert changes happen?
