High Sierra to Mohave to Catalina or??
I apologize if this is covered, the search tool did not bring up my query.
I have a Mid 2012 MacBook Pro and I have been waiting to upgrade the OS until I bought an SSD. That day has come and I have some concerns and need advice on the best way to do this.
1. I have backed up and rebooted on my external drive via Carbon Copy
2. First question, should I upgrade my internal drive to Mohave first and then back up again on Carbon Copy cloner? Or leave the backup as is and have that as the last working OS I have success with?
3. Once the SSD is installed, I will boot from my external and install am install a clean file of either Mohave or Catalina. If Catalina is worth it I will go this route. The next step I will migrate my user files over from the back up external which is the old file format and high Sierra.
a. concern I have is in the new file system. How does that work with my backup being the old way and Catalina being the new? What steps should I take? Should I convert my external music files? With the new iTunes apps will all the playlists and rankings be destroyed in my iTunes user file?
That is what I would do however I don't know what the right way is to eliminate errors, slowdowns, etc. The SSD is a crucial 1tb and I would like to have a brand new OS on it before migrating. Please, any thoughts on how to do this right?
Ditto the above, the thing with Catalina is it installs a data drive, it does some funky partitioning that previous iterations of the OS didn’t do before, so a clean install and then a migration is your best choice.
I would go with Mojave because you simply need to run the macOS Mojave installer, and you are ready to go. It will help you install new files as well.
