I have an early 2011 MacBook Pro. I want to try Sierra as most of the software I want to use no longer works on Mavericks. I went through a number of post that I can install Sierra on 8 GB USB drive but that turned out only to be a macOS installer thumb drive.
I am interested in installing Sierra on USB drive just to test drive it and to run my favorite software. I bought 16 GB USB for that purpose but only found out it cannot be installed there for lack of space.
Can somebody guide me, can I have Sierra USB Image that I can load on USB and test drive it or can I install it on USB and run Sierra from it whenever I want it.
