My 2015 Macbook Pro is still unusable when installing the Apple critical security update that was released last week. Once installed, reboots & nothing. Cant use any of my apps including ones that came with OSX.
I thought it may have been Filevault’s doing so I restored from Time Machine the 1st time I installed it, then gave it a couple days & tried installing without FileVault turned on. Well same result. 2nd restore of time machine is now in place with no updates to the patch with no plans to install it in the future.
The error message:
You cant open this application “App Store” because it may be damaged or incomplete
Not sure what to do at this point. Nothing is hooked up externally at this point. Every time I install it the only thing connected is the power supply. Unable to grab the logs as I cant even open terminal at this point. I suppose I could’ve tried single user mode but I just needed my machine back so time machine saved the day once again.
If you’re not backing up your stuff, well you have a problem. Do it now!
Update 2-3-17 this ended up being a hardware issue with my laptop. It needed to be sent out for repair where they replaced the logic board and installed a new Retina display – was not a software issue
