The issue doesnвЂ™t stop at preventing you from downloading or using the downloaded OS X Mountain Lion installer, however вЂ“ it also prevents you from re-installing Mountain Lion using the Recovery partition. Further, if you happen to have the latest version of the OS X Mountain Lion installer on hand, you wonвЂ™t be able to use it, as the same error is displayed upon launching the installer. If you don't have access to a nearby Apple store, then I think your best bet will be to prod your circle of friends/acquaintances until you find one that owns a Mac, and then solicit their help.If youвЂ™re a proud owner of one of AppleвЂ™s late-2012 Macs, including the latest Mac Mini, the new ultra-thin iMacs, and the 13-inch and 15-inch Retina MacBook Pro, you may have a more difficult time than usual re-installing Mountain Lion on your Mac, or restoring from a Time Machine backup.ДЄ strange issue affecting these Macs renders it impossible to re-download the OS X Mountain Lion installer from the Mac App Store, resulting in an error stating that your Mac is not compatible with Mountain Lion (despite the fact that it shipped with Mountain Lion in the first place).

It is possible to create a bootable OSX install usb drive from windows (google 'make osx boot usb from windows' for instructions) if you have downloaded the installer file, but there's no straightforward way to get the installation file if you haven't already. You'll need to supply them with a USB drive (8Gb or larger), and possibly buy them a beverage of their choice to say thanks afterwards.

Ask a friend/acquaintance at work/school who owns a mac to download the Mountain Lion installer from the app store and use it to create a bootable USB installer drive.

Call a nearby Apple store and make an appointment with the Genius Bar/Grove/whatever it's called now to have them install the OS for you (or at least create a bootable USB install drive).

Try the Internet Recovery again using a wired connection.

I would probably try the following (skip any steps you've tried or can't do): You're in a slightly tricky situation if you can't get the internet recovery to work. (above link is also on the page to high sierra)

It also possible to get form apple store if you haven't removed everything on your disk. They also warned about other site might have virus in there releases, this made me got worried so I have my own release here(just joking its from the official apple site): Most of the guides had links to thiere own High sierra release (seems like this is the best option to use since it still gets updates and work with old macs).

I also found a lot of video guides with instructions on how to install the osx on the drives. However it worked with a harddrive with external power source. I tried diffrent usb memory sticks but none work. I had same issue on imac from mid 2009 with os x Lion.

Install from USB drive with own power supply, seems not to work using usb stick.

I then purchased a caddy and replaced the optical drive with the SSD inside the caddy. Installation succeeded when installing onto the harddrive connected via USB. Turns out that something was wrong with the SATA/IR cable connecting the drive to the logic board. Which translates to something along the lines of 'The installer payload failed signature check'.

Using a Macbook Pro with OS Sierra I got an USB Boot disk created, ran disk utility and started the install, which after about half an hour stopped the installation with the message: Does anybody know how to get fix this installation issue?

The error message is in Danish and translates to something like: 'CanвЂ™t download the additional components needed to install Mac OS X'. Here's what I've done: installed SSD, connected power, Ethernet, booted into Internet Recovery using Command+R, formatted the disk using Disk Utility (Mac os Extended - Journaled), started re-install.Д«ut then it gets the bar filled, stalls there for long time and the it I am trying to fix a Macbook Pro from around 2012/2013, the hard drive failed so I replaced it with a Sandisk 120GB SSD and I am trying to reinstall OS X Mountain Lion using Internet recovery.
