So I have some less powerful hardware, that's why I'm installing High Sierra in 2020. Anyway, I'm trying to boot from the USB and I get the following errors:
00:000 00:000 OCB: Missing DMG signature, aborting 00:585 00:585 OCB: LoadImage failed - Unsupported That's it. The logs begin and end there. The rest of the file is zeroes.
Bootloader: OpenCore 0.5.9 Release
Note: I used SSDTTime to make the DSDT dumps for this exact computer
Intel Core i3 (Haswell)
An Intel VGA-Compatible Haswell iGPU
An nVidia Geforce 920m GPU (part of the reason for installing High Sierra)
USB: Intel 8 Series USB xHCI HC
SATA: Intel 8 series SATA Controller
If you need more details, here's my laptop https://www.asus.com/Laptops/X540LJ/ . I have the 512GB version with 4GB of RAM
I found a lot of forum posts about people having the same error, except nothing solved mine. Also, I haven't found anything online about the error with the Missing DMG Signature.
EDIT: If anybody needs my config.plist, feel free to ask for it and I'll happily post it
I am really at my wits end here. I am hoping someone on here with more experience with UEFI and boot loaders might be able to provide insight into an otherwise inexplicable problem I am having with a brand-new system built around the ASUS TUF Gaming X570-PLUS. My gut tells me the problem is somehow related to UEFI settings, Secure boot, or some combination, but I really have no idea if that is the case.
The problem is two-fold. First, my system will only boot to a device (e.g., USB stick) under two conditions: 1) no SATA drive is plugged in or 2) when a specific SSD is plugged in (I'll refer to this as SSD1). I have three other hard drives that otherwise work (I have tested them in another system). None of them have Windows installed, though some do have existing data partitions. One of the three is a brand-new, never-been-used 1TB SSD. If I plug in any of these three other hard drives, the system will reboot immediately after POST. However, if SSD1 is plugged in it will boot to a USB stick - UEFI or Legacy, doesn't matter.
Secondly, if I attempt to create a partition, run a surface test, or install an OS to SSD1, the system immediately reboots. I can format SSD1, change volume sizes, run a surface scan, but only in a live linux environment - if I plug SSD1 into another machine as a secondary data drive (i.e., I boot to my primary boot volume), the other machine will blue screen when loading into Windows. If it is attached to this new machine, it will boot to a USB stick just fine.
I have also enabled Hot Plug, which allows me to access SATA drives that I plug in after boot. If I hot plug the brand-new 1TB SSD during a live linux distro, the drive shows up and I can see its properties. However, if I try to do something like create a partition or run a surface test, the machine will also immediately reboot.
Does anyone have any idea as to what might cause this? The only thing that I can think of that explains both problems is some kind of secure boot-like security feature, but I haven't been able to figure out how to confirm whether that is the case. In 20 years of building computers I have never even heard of anything like this. I am new to EFI systems, however, so I'm quite out of my element - this is the first EFI-based system I've set up.
After hearing that OpenCore is so much better than Clover, and that it will probably be able to boot Big Sur before Clover does, I decided to take the jump.
Running Catalina 10.15.5 18F101 with OC 0.5.9.
So far I like the result. The OS feels faster, boots faster.
And absolutely everything works (sleep, network, etc...)
So, that's it? Is there anything else I have to do?
Hi guys, this thread is to show you a new and open source app, created by me, that I called TINU:
The name means: TINU Is Not #####, the U refers to a popular software that is used to create macOS hackintosh installers (that for good reasons is banned on this forum), but the aim of the name is to explain that this app is a totally different thing from that software and works in a totally different way.
This app basically is a graphical interface for the createinstallmedia executable that is inside the macOS and Mac OS X installer apps, it is capable to create a bootable installer completely vanilla like what you do using the command line method, and also this method is recommended by apple itself. In addition to this, this app provvides to you simplicity and flexybility, and lets you to avoid most of the steps needed with every other app.
TINU allows you to create easily a bootable macOS installer without messing around with command line stuff and without using disk utility, all you need to do is use the app and then install clover on the usb drive once TINU has finished or leave it as is if you want to use it on a real Mac.
- Simple-to-use UI that allows you to easily start the bootable macOS installer creation process.
- It can work with every macOS installer app that has the createinstallmedia executable inside its resources folder (including also beta and newly released installers).
- You can use any erasable volume that is at least 7 GB of size (10+gb if you use catalina or newer versions, if the volume's drive is not in GUID format, TINU will re-format it accordingly).
- Can work with the Mac OS recovery system, so you can create a bootable macOS installer from the macOS installer itself or from the macOS recovery partition, and you can use TINU to install macOS, too.
- 100% clean: The bootable macOS installers created with this tool are vanilla, just as if you created them using the command line "createinstallmedia" method in Terminal.
- Open Source: You can verify what this program does on your computer and you can create your own version by downloading and playing with the source code.
- Does not require any special preparations. Just open the program, make sure you have a USB drive plugged in and have a macOS installer app on your disk.
- No need to use Disk Utility. TINU can format your drive or partition for you.
- Integrated EFI partition mounter tool.
- Autaomated Open Core and clover EFI folder isntaller
- Works using the latest versions of macOS and will also support newer Mac installers out of the box without requiring an update.
Features that are planned for future versions:
- Support for other languages, at least Italian.
- A computer that runs Mac OS X Yosemite or a more recent version (Mac OS X El Capitan is required to use TINU in a macOS recovery or installer).
- A drive or a free partition (on a drive which already supports GUID) of least 7 GB that you want to turn into a macOS/Mac OS X installer.
- A copy of a macOS/Mac OS X installer app (Maveriks or newer versions are supported) in the /Applications folder or in the root of any storage drive on your machine (excepted the drive or volume you want to turn into your macOS install media).
