Early-2009 or newer Mac Mini or white MacBook (Macmini 3,1, MacBook 5,2) Late-2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBookAir 2,1, MacBook 5,1) I also have a YouTube video going over the whole process. If this is the case, Please provide some advice as to the process of taking advantage of this, and please remember that I am NOT a computer programmer.Questionsor comments? Feel free to contact me at Pleasetake a look at the FAQ located at the bottom of this page as well. That is unless it is automatically handled by the OS when the upgrades are done, like on Windows systems, where a Restore Point is created before any major changes.
Also, I do not keep a backup of my computer for every time Apple decides to update my OS.
Let me explain that I am not a computer technician for Apple, and do not know the intricacies of resetting OS changes backwards.
It should be easy fix to go back.Īs to number 1, I DO realize that there is a structure check at the beginning of use of the Onyx program, but the problem is that it is not doing this, it is instead freezing the computer to the point where if you open Force Quit, it says Not Responding as if it is not working at all.Īs to number 2, NO I do not have a bootable backup of the system before the upgrade to HS, that I am aware of, and do not feel that I should be forced to downgrade back to a previous OS, just to use a program, freeware or otherwise. I am sure you have a proper bootable backup of the system from before upgrade, so you can always boot on that, reformat the drive and clone the backup back to main drive - this should take at most few hours and you are back on Sierra. So, this varies and only you can answer it. Of course, depends on what you do, hardware, and what you expect. Did you make a mistake upgrading: Considering number of issues I have with stability of the system and the security issues with HS revealed recently, I think I made a mistake upgrading. I do not believe "joke" is the right word here.
Someone is making Onyx available for free, probably working in his/her evenings and other free time, so all of us can have a tool which has been very, very valuable.
by the way, that joke is provided to you for free and with no guarantees. That is expected and described on the Onyx help screen. So plan for this and expect that it will freeze the system for that time. No chance of getting ANY attention from the system during this time, it cannot read the drive. You do realize, that first step of Onyx is to check structure of our hard drive (=SSD) and on AFS that means locking the drive, running check in place - and this manifests itself as total lock of computer interactions until it is done? Same as if you do it from DiskTool, it lock computer and only when it is done (5+ minutes for my MBP) you get chance to work back with the computer.
