I have found your comments on this thread very interesting. But in this last post I’m not clear on what you are saying about Apple devices. I have a Mac Mini with OS Sequoia 15, and an IPhone and IPad on IOS 18. If I were to change the MAC Mini I would run its disk erasure option at its highest level. On the phones or IPAD I’d revert them to manufacturers settings. Should I be doing anything else?
PS this is what Apple say wrt the MAC MINI. I have ticked all the necessary boxes so hopefully it is sufficient. There are some passwords that I do not keep on the machines, predominantly those that could cost me big bucks if they were hacked. I can remember those, (at present).
Security features for Mac mini
Your Mac mini with Apple silicon provides security features to protect what’s on your computer and prevent unauthorized software apps from loading during startup:
- Secure startup: Support for secure startup is turned on automatically. It’s designed to verify that the operating system software loaded on your computer at startup is authorized by Apple.
If your Mac mini doesn’t start because it detects an untrusted component, it starts up from a secure recovery partition and automatically corrects issues if possible. To learn how to set security options, see Change security settings on the startup disk of a Mac with Apple silicon.
- Secure storage: Your Mac mini storage drive is encrypted with hardware keys to provide advanced levels of security. In the event of a catastrophic failure, data recovery may not be possible, so you need to back up your files to an external source. See Use macOS Recovery on a Mac with Apple silicon.
You can set up Time Machine or another backup plan to regularly back up your files. See Back up your files with Time Machine, and the Apple Support article Back up your Mac with Time Machine.
- System integrity: The Apple silicon in your Mac mini is designed to verify that the version of macOS software loaded during startup is authorized by Apple, and continues behind the scenes to protect the authorizations established for macOS. This makes it harder for malware or malicious websites to exploit your Mac.
- Data Protection: In addition to the default storage drive encryption in Mac mini, third-party app developers can use file-level encryption to better protect sensitive data, without impacting system performance.
Note: In rare circumstances, such as a power failure during a macOS upgrade, your Mac mini may become unresponsive and the firmware on the chip may need to be revived. See the Apple Support article
