Please make sure you use a valid email address that can accommodate the file size of the software you are purchasing. If you need your software resent to you in the future, it will also be sent to this email address. In order to use your downloaded software, you will need your serial number, which will be sent to the email address on your order. You must accept the terms of the Alsoft License Agreement. To install and/or run the software on more than one computer at a time, you will need a separately purchased copy of the software for each of those computers. It is certainly possible to end up in a scenario where the Mac is bricked completely and if you don't have a second Mac you will need to take it to a repair shop to get macOS re-installed.You may install and/or run the software on only one computer at a time but you may install and/or run the software on any computer owned by you. The combination of system board soldered RAM/CPU/SSD and the tightly coupled SoC to HBA RAM with fabric connectivity instead of a PCIe bus plus Secure Enclave hardware encryption makes it even more important. That is why backups are absolutely critical with the latest hardware from Apple. Especially engineers and those taking deep risks messing about trying unorthodox things or even orthodox things that used to work but no longer do with Apple Silicon Macs. Most people will never brick an Apple Silicon Mac but people have done it by mistake. With the Apple Silicon Mac's you can't use Internet Recovery nor can you boot off external drives if the internal drive is gone and you will need a second Mac running Apple Configurator 2 and use a DFU Reset recovery method (much like an iPhone) to re-install macOS on the Apple Silicon Mac if you managed to brick it that badly. But it could still happen if they happen to power cycle the Mac at the worst possible moment during a firmware update on a T2 equipped Mac. Apple has since put up text to indicate that it may appear off but it most certainly is not and to not interrupt the process. They received the macOS update and it ran and while it was updating BridgeOS (firmware update) they thought it powered off and held the power button till it booted and then they couldn't login to the Mac and all their data was lost. This actually happened to dozens of users at my company. The only choice at that point was to perform an Internet Recovery to re-install macOS. If you had no backup your data was gone with no chance of recovery. If the private key is gone the public key pairing will do you no good whatsoever. The recovery key is a public key which has a private key pairing stored on the Secure Enclave within the T2 Security Chip co-processor SoC running BridgeOS. Thus leaving you with an encrypted disk you could not recover even if you had the recovery key. Thus interrupting a firmware update to BridgeOS running on the T2 chip and reset the T2 Secure Enclave meaning they wiped all the private keys out. There have been firmware updates from Apple where the MacBook Pro w/T2 screen and all the lights go out and it really looks like it's been turned off and people went and manually held the physical power button as a result. Encryption seriously complicates recovery. If you have a backup, you don't need to repair or recover from disk failures.Īny Mac with a T2 Security Chip (iMac Pro, Mac Pro (2019), MacBook Pro's 2018+) or now the M1 Apple Silicon Macs are factory encrypted out of the box. I cannot stress enough the importance of backup in todays world of SSD and hardware level encryption on the newest Macs. But if that fails and you have an HDD with bad sectors then something like this should help considerably: Again, Disk Utility is recommended for any normal maintenance and repair.

That being said, most of the 3rd party products for APFS offer more data recovery features than disk maintenance features. Then they added Fusion Drive support after that. APFS was never really designed for HDD's and support was added later on after the initial release of APFS. I have a tens of thousands of PCs and Macs at work and it is extremely rare for an SSD to fail. Today's SSD drives are ridiculously stable and reliable. Typically you would run the First Aid at the lowest level first and work your way up to the Container and then the Physical Disk. But the built-in Disk Utility should be enough especially with modern SSD drives. Since then there are a few vendors who have added support for APFS.

APFS is proprietary to Apple and arrived with High Sierra in 2017.
