Installing El Capiton on an old Mac Book Pro today, I received the error:
OS X could not be installed on your computer
As explained here, OS X 10.11 'El Capitan' fails to install because it is too old (the technical reason being that the signing certificate is no longer valid). But you can trick the OS X installer into thinking that it is 2017 and it will happily run without any errors. How to trick the OS X installer. The installation was successful without any issue, and the Mac Mini is working perfectly fine until mid-October. All update was done. In October, I attempted to install MacOS Catalina through 'macOS Catalina Patcher' but no success (by both upgrade and clean install).

I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported.
After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.
You can easily reset the time and date by following the steps below:
- Click Utilities on the menu bar
- Select Terminal
- Type date
- Confirm the date is wrong
- Type date 062112422016 (example: June 21st 12:42 2016)
- Exit terminal
- Click Restart
Once the Date and time are configured you will be able to install OS X.
Easy fix, for a ridiculous error! Download partynextdoor not nice mp3.
Dear Friends,
I am unable to install OS X El Capitan on my MacBook Pro running 10.6.8. I downloaded the OS X El Capitan from App Store and when I follow the installation instructions, I get this error 'This disk cannot be used to start up your computer'.
I referenced the details mentioned here: https://support.apple.com/en-us/HT203482 (Installer reports 'OS X could not be installed on your computer' or 'This disk cannot be used to start up your computer'), and the problem I am having is that I don't have a Partition on my hard disk. Unfortunately, I do not have a 'startup disk' either and thus I am not sure how to go about installing OS X El Capitan at this time. The instructions says 'If possible, back up and reformat the target disk before installing'.

El Capitan Could Not Be Installed
I do have External Hard disk that I can use to create a backup using Time Machine, but I don't know what to do after that. Should I also copy the OS X El Capitan installation file that currently exists on my Mac Internal Hard Drive on the External Hard Disk? What should I do after I create backup on external hard drive? I have lot of data and software on my Mac and don't want to lose them all in the process of formatting the internal hard drive.
I am complete n00b with the upgrade and need assistance.
