Apple has worked hard to make the transition seamless but there are a few things you can do prior to upgrading.We all hope that it will never happen, but even Macs sometimes break. MacOS High Sierra, versioned as 10.13, includes.Preparing for High Sierra The latest version of macOS, High Sierra, has some major changes for the Mac including a new filesystem , APFS. The new software update includes a variety of refinements and enhancements to the Mac operating system, along with a handful of new features. Apple has released the final version of macOS High Sierra, available to download now for the general public. Download Macos High Sierra 10.13.6.

We've been busy testing High Sierra over the summer, and I'm happy to say that we're ready for it.вЂњBefore you return your Mac to us, be sure to enable FileVault and back up your data. (link is external) we can expect to see it on the App Store on September 25. On Tuesday Apple announced the release date for macOS High Sierra. By Mike September 14, 2017. AppleвЂ™s advice is brief, but makes the two most important points:Preparing for the upgrade to macOS High Sierra.

Consider creating another APFS volume using Disk Utility, making that encrypted, and moving the sensitive files to that. If your Mac has a T2 chip, turning FileVault on is instantly effective, as all the data stored on its boot disk is already encrypted itвЂ™s still worth turning it on, though, as that requires your password before the encrypted files can be accessed.If your Mac doesnвЂ™t have a T2 and FileVault isnвЂ™t turned on, encrypting your whole boot volume can take a very long time. If the boot disk is already protected using FileVault, you shouldnвЂ™t need to do anything more. A clone copy made using Carbon Copy Cloner or SuperDuper gives you added flexibility, and a second copy of everything on your Mac.If you store data on your MacвЂ™s internal storage which needs to be protected, you should also think carefully how best to ensure that it remains safe while your Mac is in the care of others. Time Machine backups are invaluable, but sometimes donвЂ™t work perfectly.

If your Mac boots into setting up macOS, you can follow the setup, and opt to migrate from the external clone or your Time Machine backup. If almost everything on your boot volume has vanished, you know that its internal storage has been wiped or replaced.If your Mac has a T2 chip and you want to use a bootable clone to restore its contents, now is the time to open Startup Security Utility and enable it to boot from an external drive (see below).If you need to restore your MacвЂ™s internal storage, you now have a choice of routes for that journey, which include: If it goes straight into the macOS setup sequence, restart into Recovery Mode and open Disk Utility. That way, thereвЂ™s nothing else to go missing.When your Mac returns, connect it to a minimum of essential peripherals and try starting it up normally.

So long as youвЂ™re using a current version of the cloning tool, you donвЂ™t have to turn Secure Boot off at all. Try this on an older model with a well-loaded SSD, and it could be many hours before the volume is encrypted.The only real complication with a T2 is when it comes to letting it boot from an external disk, if that is how you have decided to restore your internal storage when the Mac returns. In fact, those newer models have one great advantage: the ease and speed with which you can turn FileVault on prior to sending your Mac away. You can set macOS up as a new user, and migrate using Migration Assistant afterwards, or migrate manually if you really want to.Whichever you choose, youвЂ™ll want to ensure that your Time Machine backup or clone is connected by the fastest possible method, such as Thunderbolt 3, to make the process as rapid as possible.A lot of users seem worried about trying to do any of this on a Mac with a T2 chip. Remember to use the Startup Security Utility in Recovery Mode to allow this for a Mac with a T2 chip, if you want that option.

It is also impossible to make such a process error-free, and the merest chance of someone else getting all your files by mistake wouldnвЂ™t be good.As it is, to protect the privacy of what is on your internal storage, Apple recommends that it is encrypted, which in turn makes it impossible to verify that a disk has been properly restored and is fully functional. No matter how careful Apple and its providers may be, that puts a great deal of trust in technicians never being tempted to access sensitive data. If no boot volumes were encrypted, Apple and its Authorised Service Providers could automatically clone every internal disk on receipt, and restore those they needed to prior to despatch of the repaired Mac.There are several snags with this, most obviously the fact that it would risk giving service technicians access to all your files.

ThereвЂ™s no risk that they will try to crack your encryption вЂ“ especially with T2 FileVault, which as far as I know has never been cracked вЂ“ nor to put it into a forensic rig and start trying to recover deleted files. If you leave sensitive data in plain view on your internal storage, there is always the small risk that a technician might be tempted to steal it. Service providers take measures to try to ensure that this doesnвЂ™t happen, but canвЂ™t guarantee it, as Apple says. DonвЂ™t fall into the wrong hands. It is well established that the encryption provided by FileVault with a robust password is sufficient to demonstrate that you have met your legal obligations in that respect.The other is your own concerns to ensure your bank details etc. The first is that much sensitive data is covered by data protection legislation, and you as the custodian of that data are expected to take reasonable precautions to prevent its inadvertent disclosure.

I still cannot see any use for it: if the SSD is broken, it is much better to physically destroy it. There is no case on record as far as I know that anyone has ever been able to recover data during or after that process.Some time ago, someone asked me to write a tool to вЂsanitiseвЂ™ an SSD in the way you propose. If the internal storage is faulty, then it goes for recycling. The broken logic board goes back to a factory where it is tested for faults, any possible repairs are made to it, and it may then return as a remanufactured logic board for use in a future repair.

What I meant was a method which made impossible to access such data. One of them is to gain access to the device and even the password.I think that I did not explain properly. It is not impossible to break a password or security measure like T2 chip. I understand what you say, but one thing is that as far as we knowвЂ¦ whatever, and other thing is that something is impossible. If you want to ensure that your data are not recoverable, encrypt them вЂ“ that is the whole purpose of encryption.Thanks. If youвЂ™re passing your Mac on to someone else, the standard procedure for reformatting and installing macOS is absolutely fine too.

Do you know if there is such application? If not, it would be great if you could make it. That is what I meant and it would be great if an application could do it automatically (simply filling the disk overnight, duplicating a file a said above). Simply because such data does not exist any longer.One way is to physically destroy the disk, but that may not be desired or possible (cannot easily open device, like current iMac, unless using special tools, with danger of breaking Mac and voiding warranty).Other is to format disk and fill it completely leaving 0 bytes left. Even for the owner of the device and password.
