Losing the data on the devices and then the recovery process for it has always been an aspect that made the users concerned about the data. But recently, Apple has brought up a new data recovery process internally for Macs, which uses the T2 chip, which has been brought by Apple in iMac Pro and the 2018 MacBook Pro.
The new process for the repair staff has been brought because of the advanced security features of T2 that includes hardware encryption for SSD storage, which is not compatible with previous recovery methods of Apple that were used on the older machines. Here are the advanced security features that the T2 chip possesses:
In the MacBook with T2 chip, even if you have not opted for the startup disk to be encrypted with FileVault, your startup disk would still be secured due to the encryption by the T2 chip. This is how your MacBook will stay in Full Security mode with booting from external media disabled. Thus, we can say that the MacBook with T2 chip would always stay encrypted, irrespective of the fact that you have turned on the FileVault or not. The only difference that will be there is that if you select the FileVault to be off, in that case, the encryption will be unlocked by using the internal hardware UID (which is kept in the Secure Enclave of T2 chip), and then it will not use your password.
The amazing thing about FileVault with T2 is that there is no need to have any further encryption to enable it. It would be instant that there would only need to involve the T2 shuffling some of the keys. So, in case you are not sure about going the whole hog and enable FileVault when setting up, you should know that there would not be any penalty if, in any situation, you change your mind.
In case you want to start from a different version of macOS, you would not have to go to the Full Security option, but probably the Medium, or even allowing booting from external media too. If you have to run Windows using Boot Camp, you can do under Full Security; also, you need to use the latest version of Boot Camp Assistant.
No wonder, with the T2 chip in MacBook, Apple has increased the level of advanced security features, and to add more to it, it brought up the new recovery process that makes it feasible to retrieve the data from the system. Let’s find out the different aspects which are there in the document brought up by Apple that mentions the new recovery process from the MacBook using the T2 chip.
Here’s the information from the document released by Apple
The new data recovery process that will use the T2 chip of the Mac will be used by the repair staff for recovering the data from the system of the customer. It would be done when the customer would reach out for the logic board repair, but it is necessary that the logic board should be partially functional. Apple added that it is necessary that the system should be able to power on to get the recovery process working.
Apple mentioned in the document that the repair staff would use a Thunderbolt 3 (USB-C) to USB-A or Thunderbolt (USB-C) to Thunderbolt 3 (USB-C), a host computer and an external hard drive in which they will be transferring the data for completing the recovery process. The machine that has got damaged would then be switched to DFU mode, after which the internal diagnostics tool of Apple would be utilized for initiating the recovery process. Also, Apple said that the tool would take around 10 to 20 minutes for partitioning the external hard drive. But when it comes to the data transfer time, it might take as long as two days to get transferred to the external hard drive, which completely depends on the amount of data that needs to be recovered.
The new T2 chip came up with many security features like on-the-fly encryption, and with the new data recovery process, Apple has proved it’s worth more. Not only this, but T2 also offers various different features in the new MacBook Pro and iMac Pro. These new security features will offer additional protection against potential cyber threats, which have been becoming critical these days. The risk of data theft can be significantly minimized in the Macs that are using the new T2 chip.
