Jan 27, 2015 - The release notes accompanying the download of OS X 10.10.2 are as. Installing 10.10.2 unless 10.10.3 is verified by users to be a real fix. OnyX (Lion) for Mac is a maintenance and optimization software tool created to evaluate the integrity of startup files, but it can do more than checking and verification.

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! I ran 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?
