Also you can take your mackbook for a short while to an air conditioned ...

I just encountered the same problem.
And this is the window. It's really hard to read text with the lowest brightness. I hope this image helps someone who has the same issue.
In this screen, you can't select the checkbox by tab key.
You have to use mouse cursor that is located at the top-right corner.
The problem was solved by clicking the Previous ...

When you use target disc mode, do you need to use a Mac with a similar OS..? I have an older iMac I could use but it's running 10.6.8 compared to 10.11 on one side of the partition and 10.14 on the side with that's full. It's that side I want to clean out so it'll boot again.
cheers!

I'm the author of the Apple SSD article that klanomath linked to in their comment and I wanted to clarify some things that seem to have been misinterpreted.
First of all, the Mid 2013 release of the MacBook Air 11" absolutely can use the faster PCIe 3.0 x4 drives from the 2015-2017 MacBook Air 13", which I refer to in the article as the Gen. 4A SSDs.

That photo says the kext (driver) for the Atheros airport card is what's causing the kernel panic.
There's a very simple way to disable this kernel extension, although it's terribly hacky: go into /System/Library/Extensions/, and rename IO80211Family.kext to IO80211Family.kext.bak.
Afterwards, go into the Terminal and run sudo kextcache -i / to rebuild the ...

To my experience, it is a question of Secure Tokens, if it doesn't accept the admin even though it has the shipped (old) macOS installed from the recovery partition.
Even though you have created an admin account, you need it to have a Secure Token and update the preboot, for the recovery partition to accept it.
I did the following (when logged in as the ...

No. These SSDs are not compatible.
The 2013-2015 MacBook Air 11" uses a proprietary PCIe 2.0 x2 SSD.
The 2015-2017 MacBook Air 13" uses a proprietary PCIe 2.0 x4 SSD.
The 2015 through 2017 MacBook Air laptops use the exact same interface, so, those are compatible. Also remember that you're comparing the 11" to the 13" model and those are different with ...

No, the firmlinks are bidirectional so you should have two pairs of filesystem if you need separate systems. The good news is that with space sharing and the smaller size of the system, having two Catalina around is ~22 GB for my Macs.

Your symptoms are either a bad driver / os for the video subsystem or a hardware failure.
In case of hardware, safe mode will often run since it doesn’t ask as much of the video system which runs in a fail safe / basic mode. Also, it can slow down the rendering so you can easily see the failure modes or grab a screen shot.
Before paying for a repair, ...

What makes it bootable? This has change slightly over time. I will assume you are not going to use encryption. Below are some basic examples. This is not a complete list.
The original OS X operating system.
The partition should be type 48465300-0000-11AA-AA11-00306543ECAC.
The partition should be JHFS+ formatted. If you are using the Disk Utility, you ...

The Microsoft bootloader program bootmgfw.efi is found in the EFI partition on disk either in the EFI/Boot directory, the EFI/Microsoft directory or both.
While it is acceptable (according to UEFI specifications) to have several EFI partitions both Apple and Microsoft expect there to be only one.
You say "I reformatted the entire drive" but unless you ...

According to @David Anderson (thanks!), the 2010 iMac came preinstalled with Snow Leopard 10.6.3. Therefore, there's a good chance that earlier versions of Snow Leopard (10.6.0–10.6.2) will not contain the necessary drivers for your machine, and will be impossible to install.
Apple released at least two retail Snow Leopard installation DVDs—I own one which ...
