I'm trying to wipe my old mac book but now that I have erased it, it will not install the OS. It comes up with a message to say No Packages were eligible for install. Every time I revoot it says the same. I have tried changing the date but just then get a message saying error when trying to run the installer. It is a fairly old mac book
MacBook
Did you erase the mac correctly.
Boot to your Recovery HD,
Open Disk Utility press Continue.
Highlight the Disk not the indented Volume in the left hand panel.
Click Erase.
Give the Disk a name.
Format: Mac OS Extended (Journaled)
Scheme: GUID Partition Map
Click Erase.
When Done quit Disk Utility.
Make sure the date has been reset as above instructions.
Click on Reinstall OS X press Continue.
Hi
Thanks for this, but now when it tries to install it comes up with an error box saying error occurred while preparing the installation and wont go any further. This is so frustrating as it worked fine before I wiped it clean to be able to sell it.
Any other ideas?
Thanks
How are you resetting the date, is it by the method described below.
The certificates for several of Apples OS's expired in October 2019, Apple have been very poor at getting these updated on their Recovery Servers with valid certificates. This may be the problem you are experiencing.
Try this workaround, we are going to set the time and date on your mac to a date previous to the expiry date of the certificates.
Connect your mac to your router via cable, not WiFi
Boot to your Recovery HD, click on Utilities in the menubar select Terminal.
Make sure WiFi is switched off, it can reset the date back to today.
Enter a new date, for example or just copy and paste
sudo date -u 011421002015
press Return
enter your password
press Return
If Terminal returns an error saying sudo : command not found, then try again without sudo.
Now try downloading the OS.
If this works then when the OS is installed and booted up you can Open System Preferences> Date & Time
and reset the time back to today.
