Hello, I recently rebooted an old MacBook and erased the drive then had to go in recover mode.
Now I am stuck with an older OS and unable to make any updates.
I do have another MacBook with an updated OS, is there a way to save the os and transfer it to the older MacBook?
Alternatively, how can I fix this problem?
No, you can't use/save a current OS from another mac and transfer to your mac to upgrade.
The procedure would be download a copy of macOS and install.

What is the older MacBook Pro model/year? and What macOS version you intend to upgrade?
If you have hardware or software that isn't compatible with macOS Catalina, you might be able to upgrade to macOS Mojave.

Other ways to install macOS:
create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.
Thanks, the laptop I am trying to upgrade is MacBook Pro (13-inch, Mid 2012).
I hope I can update to the most recent version without having an issue running most applications.
I will opt for the bootable installer, but is there a way to save a current OS I am already using on another laptop?
When I am trying to download a certain version I am afraid it will apply to the laptop I am not trying to fix (which is fine as it is now).
MacBook stuck at OSX 10.8.5
