App Store not working on my mac

same happened with me

any suggestion ?

I found my answer on this thread: https://discussions.apple.com/thread/5606157.

Resetting the NVRAM worked on my circa 2009 Macbook running Mavericks. Thanks for the tip!

This is the only fix that worked for me (Mid 2007 iMac)

Rebooting worked for me too.

Thanks rjrudi - adding the App Store to the allowed incoming firewall connections fixed the problem.

I'm not too sure whether my issue was resolved by clicking Command, Option, P and R, or simply because I shut down my computer. Either way, my issue is fixed. Thank You .

I had the same problem. The blank app store just started happening after the 10.9.2 update.

Turned out to be some Little Snitch deny rules needed to be deleted. I have no idea how or when those got added. There were maybe 40 deny rules across two dozen apps that didn't make any sense (and I'm a firewall guy too).

Thanks

Restart fixed it for me. I don't have Little Snitch or similar.

In my case DNS settings were wrong. Go to your network settings and check.

check your time and date settings. mine where off by a whole year. Once i corrected that, app store worked once more!

This worked for me, thanks!!!!! A window popped up after I held down opt-command-p-r and I didn't select anything but closed out of it, then shut down my computer. When I restarted it and clicked on software updates, the updates screen opened and showed that I had updates and I was able to select them.

Great - solution worked for me. Haven't had to reset pram vram since I had an old black Apple in the 90s. next they'll be reintroducing the reset button.

This solved my issue. Works like charm
