Hello People, Today we are going to share information of performing hard reset on Mac OS X El Capitan. If you feel that your Macbook is too slow? or freezes too often while in use or keeps getting an error message due to software crash or has a problem with a forever loading time, we would like to recommend you to perform hard reset. Hard Reset is to restore your Mac to its factory settings, therefore you can feel that your Mac gets much more faster after hard resetting. There is one important thing to do before performing hard reset is to make a back-up file. Please make a back-up file, if you want to keep your data. All of your data will be erased. However, if you are ready let’s get it started!
I'm unable to complete the installation of El Capitan. I only have the HD & RAM memory installed (no battery). Other Mac OS-X Versions are installing OK (even Windows). But, when I try to upgrade to El Capitan it never finishes the update. Also, it will not install via USB thumb drive. I have tried everything! Then I used TransMac with an El Capitan image, restored the image to a USB drive in an attempt to boot into recovery mode and install using the new image onto the new SSD, which fails to work. Firstly, it won’t boot into recovery mode, I’m guessing it’s because there is no recovery mode available as it was on the old HDD and this older.

Installing El Capiton on an old Mac Book Pro today, I received the error:
OS X could not be installed on your computer
No packages were eligible for install. Contact the software manufacturer for assistance.
Quit the installer to restart your computer and try again.
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.
