bartl Posted November 9, 2017 Share Posted November 9, 2017 I cannot execute any updates? Do I have a sort of NVram problem? I tried to update from Sierra to HS by just using the installer app. (Preparation like adding apps.efi, updating clover etc. done in front certainly). The update started and after a short time it rebooted the system. Then my Sierra started again acting like nothing has been done before. Then I installed HS via an USB installer. So, to keep my Sierra partition, I shrinked it and installed HS to the free rest space. This worked fine. HS started up like expected. It looks like it is working fine on my hardware. The problem occurs after 13.1 has been released. I run the update and once again the system reboots but started with 13.0 like nothing has happened in between. My thought are currently that a special NVram entry is being placed by the installer/updater but it does not persist a reboot of my machine? Or does any one knows whats is going on with my system - because I also do not find any similar behaviour being posted in any forums? What I have done so far: 1. I tried to add a boot parameter via shell command to the nvram - was not recognised at new boot. 2. I tried to create a /etc/shutdown... script to copy nvram to disk but no luck. Clover is always saying: "PutNvramPlistToRtVars: nvram.plist not found" No further idea on my side. Link to comment Share on other sites More sharing options...
