Hi everyone,
First post on here. I hope someone else has done what I describe below and can advise re. my questions....
I have a late 2012 iMac (27 inch) which is currently running on the latest version of Catalina (10.15.7).
It's no longer getting updates and Office 365 updates can no longer be applied either.
I want to update to avoid any future issues , security etc.
About 6 months ago, I installed Catalina 10.15.7 on an external SSD and it was a game changer re. performance .
I am looking to do the following:
1) Buy another SSD and install Monterey on it (or Ventura, if it will work as well). Using Open Core patching.
2) Backup my current Catalina SSD (in case I mess things up )
2) Boot from the new drive , instead of my Catalina SSD.
3) When all is working, copy my data from the SSD and the original MAC hard drive to the new SSD (Monterey image).
I assume I will be able to use the Open Core patch process to do this (there are some good YouTube videos show how to do this and it doesnt look too complicated)?
Importantly, once I have done this, can anyone advise if Apple iOS updates get applied automatically, or will I have to do these manually going forwards?
A point to note: I currently have the original Catalina (10.15.7) iOS on the Imac (which has a standard Hard Disk - very slow).
