Hard Drive Partitioning and Removal
Reinstalled Catalina OS on a External Hard Drive. I had it partitioned with Mojave on my "Macintosh HD" - So how do I erase or remove the partition I had set up for Catalina.
Is there a way to "reclaim"the old partition space?
The total system seems to be working better by my isolation of the two OS's - It became so slow over time. Thanks in advance. jn
