Just upgraded HDD to SSD Everything booted fine and recovery mode has opened
However before installing the SSD i've made it a bootable device with clean Install HighSierra app so i don't have to rely on my poor internet speed to reinstall everything.
Now when clicking the osx Install option in recovery mode I'm greeted with an error - that this device cannot be used to install OSX, i'm guessing it's because the system reads it as bootable device...
After this i went on and tried to erase the SSD in order to format it clean but it runs into error of PID 539 using the drive.
Tried force unmount commands in the Terminal that resulted a stubborn PID 0 not letting to do it after killing the 539 one.
Seems like the system needs at least one drive to be connected. Tried adding my previous HDD via SATA to USB cord but the system doesn't read it.
My questions are:
- Can i avoid disassembling to take out the ssd and format it?
- Can i use my MacBook Pro to connect to the iMac so that it can read the macbook volume as an additional one helping me erase the SSD without disassembling? If yes then how?
- What format should i format the SSD with considering i am planning to run osx High Sierra or Catalina & Windows 10 bootcamp.
