I could look at the imagine and navigate to my Photos, which was all I wanted, but I couldn’t move anything. In Disk Utility I could see my disks, but when I went to first aid it would fail. If you are familiar with Macs you may know that you can boot them in Recovery Mode by holding command and R on startup which should provide you with some options such as restoring from Time Machine, Reinstalling macOS, getting online help, or going to Disk Utility.
So I did that and I could boot perfectly into Bootcamp, but into the Mac partition would just go through the loop. Holding option will allow you to select the startup disk. Clicking that just returns it to the same point, so it is stuck in a loop and there is no going back. The computer goes through its upgrading process and then boots and says “macOS could not be installed on your computer” and only gives me an option to restart. Problems arise Macos Could Not Be Installed On Your Computer Loop Using I considered taking the extra 20 minutes and backing up my files which they make so easy, but nah, I clicked upgrade. A week prior I had no trouble upgrading to Mojave on a MacBook and thought it wouldn’t be a problem for my Mac Mini. I did not follow Rule #1 and that is the source of all the problems.
(2) Connect the drive to your real Mac and install macOS directly. (1) Temporally disconnect unused drives for the install. This is a common trouble in installing Mojave. If you have several options because the Time Machine drive is plugged in to your computer, make sure you select the correct drive and not the Time Machine drive). Select the disk on which you want to install 'El Capitan' and press Continue (note that the icon and name of the disk will be different in your case) (there is usually only one option. 'macOS could not be installed on your computer. At the Clover boot page, I select the hard drive and when it reaches the end of the 'apple icon/bar graph', I get the message below. After reaching the language page and completing the first stage of install, the computer restarts and I select the USB to boot from. Your computer will boot into the Utilities. After doing so, when you see the Apple logo, you must release the buttons. Then immediately, press and hold the Command + R buttons. Then press the power button once more in order to turn it on. Press and hold the power button to shut down your Mac.
Rule #1: Before you upgrade your operating system do a time machine backup.
You shouldn't need to do it that way though, as your MBP has a Thunderbolt port on it. I've never tried it nor heard about anybody trying it yet, so I have no idea if it will work, but an Apple support document says it should, and if it does, you're going to need two adapters, one from Thunderbolt 3/USB-C to Thunderbolt and the other from Thunderbolt to FireWire 800 (plus a FW cable). I don't believe there is an adapter to go directly from USB-C to FireWire, as they are different protocols. If TDM doesn't work like this, it may by connecting the two Macs first, but that's another story. If you have a logic board failure, I don't think this is going to work. Again, I haven't heard of anyone using this method yet, so I can't say if it will work for sure.įirst, see if your MBP will boot into Target Disk Mode by holding down the T key while booting.
Obviously the $9 USB-C to USB cable is the least expensive, so I'd try that route first if you don't have USB external enclosures they're only $10-15, so I think that would be worth a try to get your data. EDIT, I should have put this first: If your MBP cannot start in TDM, I believe the only thing you can do is put the HDD in an external enclosure: if it's USB, this adapter should work:, if it's FW, use those adapters, if it's Thunderbolt use that adapter.
