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.
Syncdefaultsd little snitch. 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! Os x yosemite.
El Capitan Could Not Be Installed On Your Computer System
Tonight after a routine MacOS update (10.13.2) disaster struck and my Mac got stuck in an update boot loop. After a few hours of panic, reading online and trial & error I managed to resolve it. Here’s what I did in the hope it also helps someone else.
Steps
El Capitan Failed To Install
From the “MacOS could not be installed on your computer” screen: Water preserver vs regular bleach.
El Capitan Reinstall
- Press and hold “option” key and click restart
- In the “Startup disk selection” screen, use the arrow keys to select your main hard drive (not the MacOS update)
- Wait for your Mac to boot normally
- Download the latest combo update directly from Apple. (this is a full system image, not an incremental update)
- Open and install the update
- Grab a snickers, this will take a while
My environment: 2017 Macbook pro 15” Touch Bar with MacOS 10.13.1 (High Sierra) installed and tried to update to 10.13.2 using the App Store.
