Truly bizarre behaviour from 10.11.15
Hi all,
I have a MacBook Pro Late 2013 model that recently experienced its first major upgrade technical issue - basically it would freeze on start up, booting in safe mode resolved nothing and after a short period of taking an hour and a half to boot a clean install appeared to have solved the issues. The recent upgrade has made another shambles only with some truly strange happenings:
- Start up is slow - ridiculously slow (1.5hrs)
- When waking from sleep - nothing works. Shut down required.
- The login screen appears twice - my user account only on the screen. Password entered and hit enter. Screen Dims. Same screen appears. Password entered. Actually enter the account.
- As a safe guard, I have created a second administration account that has been set up and accessed as to ensure it is operational. This is never visible at the log in screen (and yet the guest account that has never been active is present sporadically by default on start up) This second administrator account is only accessible once logged into the original created account which continues to degrade.
- Any interruption or change in state of bluetooth or wireless requires restart to resolve or it will never reconnect. Wifi connectivity is dodgy but I know thats a thing and won't whinge about it here.
- Keychain is practically useless - its asks for passwords on behalf of individual apps for about 20 minutes at a time - I've restored it, deleted it, disabled it, running first aid is greyed out - for my sanity and a consistent network signal I have not disabled it but systematically starving it of the requested data. Its annoying to dismiss it constantly but its better that than having it gorged with precious system keys that allow it to juggernaught through my network services demanding that everything stop because it needs another password entry for an app to use.
- The mac refuses to ever start in safe mode. I can try until i am blue in the face and it won't ever do it. Normal mode even when it looks like it is shifting to safe mode. The one occasion where it looked like safe mode (written in red in the title bar) the label disappeared without restart.
- When i select shut down - the mac will shut down 1 in 4 times. The remainder of the time it sleeps (as after shutting down, there is no apple logo and loading bar - simply the login screen as if it were sleeping - even though restart or shut down have been selected)
- Very strange SCWTL-#.wvx files appear in my download files and the following messages in console kill everything to do with the network immediately:
- CONSOLE entry for this which is bizarre is from quicklooksatellite and is as follows:
- [22:51:50.787] <<< FFR_Common >>> FigFormatReaderCreateForStreamReturningMatchingContainerLabelType: *** Could not find format reader for URL "file:///Users/JD/Downloads/SCWTL-3.wvx" path "/Users/JD/Downloads/SCWTL-3.wvx" extension "wvx" FileType '' MIMETYPE "(null)" SuggFileName "(null)" SuggNameExtension "(null)"
This is some of the odd behaviour. I would be really grateful if any of these could be explained. Its very weird as I have not initiated any of these behaviours and I like to think that I am a cautious browser only looking at legit sites and never clicking on silly email links etc.
Thanks in advance
