I can't open the App Store, and I can't open software update. I've tried all the troubleshooting advice I can find online, but none of it solved my problem, so I figured an OS update was overdue. I'm hoping that will fix it.
I can't seem to update without the app store, though!
sudo softwareupdate --install —all and restarted (
sudo shutdown -r now), but "About this Mac" still tells me I'm on 10.9.5. (Again, clicking the "Software Update" button tries to launch software update, but fails.)
Now, when I run
sudo softwareupdate —list it says, "No new software available."
Is there anything else I can try before I have to take it to the Mac store?
