Hi.
I got a problem with my Mac on Catalina.
I think it's definitely a software-related issue.
So my device is a MacBook Pro 13" 2014 (A1502).
I upgraded the SSD from 256GB to a Corsair MP510 960GB SSD using an adapter from Sintech(i believe).
Installation of the OS worked perfectly fine, i just had to make a live-boot Ubuntu-Drive to format the SSD before starting the installation.
Everything but installation of updates for the OS and installation/updates of apps that use the old installer works....
When i try to install updates by clicking the button in the settings>software-update, it restarts and the white progress bar appears.
But then everything takes way too little time and im back in Mac OS.
Then i search for updates again and it seems like the update wasn't successful. Thats the case. Sadly.
In Disk Utility, i can see a container with two deactivated volumes in it.
When i try to activate them i get a "com.apple.DiskManagement.disent"-error.
Searching Google didn't help there.
Updates in the App Store don't show up and when i try to install apps that use the old installer where you have to select a drive to install the program on, no drive appears.
The same happens when i go into settings>boot volume. There doesn't appear a disk/volume, too.
I will attach screenshots of the problems as far as possible (i'm german, so the system language is set to german too :/ sorry).
I don't know what to do, so i thought i'd seek for help here.
Thanks in advance.
