I was trying to reformat an old MacBook Pro which can only be upgraded upto Catlina on its HDD but its not working.
Basically I received an old device which was experiencing fragmentation related hang ups, so I did what you would normally do on any operating system installed on a HDD which is to format the drive and reinstall the OS. I went into recovery mode, selected the top most option in the hierarchy to format (in Disk Utility), and then I had to choose the file system format. I read on these forums that mac os extended is the way to go for HDDs so I reformatted from AFPS to mac os extended and it worked. But after I reinstalled Catalina on it the end result was that it reverted back to its original format which was AFPS.
I tried reinstalling from a bootable drive but there was no difference. I also found out on this forum that many users were experiencing problems upgrading to Catalina because it requires AFPS. So is the installer re-reformatting my drive during reinstallation? Is it impossible to install Catalina on a drive formatted to mac os extended? Is it possible to find out the original drive format and scheme the device was originally setup with?
