Then the external drive would share the Applications, Library, and Users folders with my Mac? Wouldn't there be a risk of adverse effects and incompatibilities between the two systems?
2) If Apple releases a software update for Mojave, which is on the external drive, how would that work? Would I be alerted the next time I booted from the Mojave drive and the update would be applied to Mojave without affecting the High Sierra system on my Mac?
I am risk-averse and don't want to do anything that might mess up my primary Mac.
Thank you |
When I boot off the external drive, I can't even see the internal drive. I'm sure I can use disk utility to make it accessible, but by default it's not visible. You will need to reinstall all of your programs. You have totally different versions of of all your apps.
I'm sure if it was important, one could tune this all to make it a lot faster, but I find my current set up of keeping an old mac mini for such tasks good enough. For your use, I suspect that eventually, someone will update the De-DRM tools to be 64 bit compatible.
