i’m stuck and urgently need assistance!
I have rMBP 15″(MacBookPro A1398(mid 2015)), currently running Big Sur. The idea is simple, i just want to jump on Sequioa via OCLP(my rMBP is not supported anymore), since for development purpose it requires to have latest version of MacOS.
The problem appears here, since i have a bunch of data / apps / settings and etc, which never was saved before and i would like to not lose it before upgrade process.
I have an empty SATA3 SSD and SATA3 <–> To USB adapter. Plus additional Backup drive (NTFS) where i store files from my personal Windows machine.
What i’m trying to achieve :
-
Create Image disk with full clone of my current MacOS BigSur AS IS, which should contain all files / settings / apps and etc. After that i want to copy that Image on my NTFS backup drive and possible later i will move it to Cloud(e.g. OneDrive).
-
Create a full bootable clone on external SSD and keep it there temporarely while upgrading via OCLP. If it crashes(i hope its not), then i can erase\wipe my internal ssd and just clone again from external SSD freshly copied version and repeat process(
or maybe full wipe and clean install, which I really don’t want to do, its completely other story / question)
Note #2 seems to be not a huge problem at all, since i could use at least basic Disk Utility for such job.
Note #1 its more complicated, since i’m not “advanced” user of MacOS, to be honest i’m not even sure if that scenario possible / applicable, because i have no idea how in fact looks fully bootable Image of cloned MacOS system, i guess it should be the same how it works in Windows manner where you get Image as one file with format “.iso“, but for Mac it will be one file as “.dmg“.
Also, i had in mind to use Time Machine, but this is much more complicated and not best solution for my case, since of you can’t just copy/paste files from Time Machine, because under the hood it uses symlinks.
Any advice appreciated.
PS Could be possible through 3rd party apps like CCC, but unfortunately i didn’t found anything similiar on my request…
