Hi everybody. I work with my personal Macbook Pro M1. I installed a second Mac OS just to work for the company. When the system boots, the volume of the second system is always connected, every time I disconnect it through the disk utility. Please tell me how to disable the automatic connection of a neighboring disk volume.
p.s. Or is it better to encrypt the disks(FileVault) so that there is no access from one system to another???Thanks
Yes, you could enable Filevault on each volume so that you won't see the other volume. With the newer Macs, having more than one volume with Filevault enabled could make things tricky when you try to boot into recovery mode. Plus each time you boot, you will be prompted to unlock Filevault on the other volume.
Or, You can put an entry into the "fstab" file to prevent the automatic mounting of the other volume. You can do this for each OS so you won't see the work volume when booting into your personal OS, nor the other way around. Another respected forum contributor has created the instructions to do this here:

¿Do you actually need different Versions of MacOS for personal and for business uses?
If NOT, you are duplicating the wrong thing.
The things to have two of is User Accounts, provided the accounts are not Admin accounts. User accounts are STRONGLY protected from each other in very fundamental ways. macOS is inherently a multiple-User system, even if you choose to create only ONE account.
To use, log in to your business account when doing business things, and log out when not. Your personal files and NOT accessible from the Business account.
Log in to your personal account when doing personal things. Your business files will not be accessible.
A separate account can be use for Administration and Software Updates, or the Account you trust the most can be the Admin account. Admin account can get access to everything.
I don't fully understand your issue but I will offer the following. When you have more than one operating system installed you can open System Settings and the Startup Disk link within General settings on the left is where you can set which OS the computer is to start up with. Optionaly, you may also press the Option key when starting up to select a different OS to start up on a one time basis.The Disk Utility app is not involved.
Thanks for the answer. But this company installs programs that control working hours, monitor the file system (the software runs with root privileges).I enabled FileVault for a personal MacOS instance too, I think this is the best option.
When early Mac Pro 2009 Desktop was first available, a perforce-minded Blogger who publishes MacPerformanceGuide reported the he had INCREASED performance by using an External drive as his Boot drive, and placed all his editing footage on different external drives.
Similar to that, you could add an additional [possibly Bootable] External drive, and use it for your business MacOS, or for your personal MacOS, or for your private files. Then you could disconnect or eject it to separate your personal and business files.
Thanks for the answer. But I wanted to isolate the MacOS instances one from the other
This is exactly what I need, thank you very much.
which?
enable FileVault?
prevent other Volume for Mounting by modifying fstab?
Two MacOS on one MacBook and neighboring disk volume
