I need help restoring my Mac desktop to an older version of Mac OS. I am following the outlined steps, it keep getting the same error message. I have a hardwired inter connection, so it is not due to an unstable internet connection. HELP!
iMac 27", macOS 10.13
The certificates for several of Apples OS's expired sometime in October, Apple have been very poor at getting these updated 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.
Boot to your Recovery HD, click on Utilities in the menubar select Terminal.
Enter a new date, for example
date -u 0104210218
press Return
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 to today.

Did you try the date command with sudo as suggested above, what error did it come up with
if you want help you really need to provide details.
Of course you will get the error, the server has a copy of Mac OS X Lion that has expired certificates
that is why we are trying to change the date through Terminal to a date preceding the expiration of the certificates
so that you can get it installed. There has been plenty of success on here using this method, read the other posts in this community.
Apple will not look at the logs, Apple will not look at your mac as it is considered 'obsolete' by them,
that does not mean it will not work or can be got working.
High Sierra should be no slower than any other OS, a minimum 4GBs RAM is recommended (2GBs is not enough) sometimes you are better sorting out your problems rather than going backwards. What apps were not compatible with High Sierra, could you not find updates or alternatives.
Before upgrading you should always make a full back up if not two. Always check your third party apps for compatibility
with the new OS, and always check that any printers/ scanners etc have updated drivers and software.
As your mac is on High Sierra and you want to wipe the Disk properly, boot to Recovery
open Disk Utility, click View in the menubar, select Show All Devices. Now click on the Disk
not the indented Volume. Click on Erase, give the Disk a name, Format: Mac OS X Extended (Journaled)
Scheme: GUID Partition Map, click on Erase.
Lets try the Date again open Terminal from Utilities in the menubar select Terminal
enter the text
sudo date -u 0104190018
press Return
Now try reinstalling the original OS.
What error did you get in Terminal it should be a pretty easy process. did you copy and paste the command I typed in.
If you are trying to install Mac OS X Lion, did your Mac come with Lion pre installed, are you following the instructions
in this article, How to reinstall macOS from macOS Recovery – Apple Support
What mac do you have, what year is it.
I couldn't execute the date command in Terminal (even though I am the computer administrator), so I manually set the date back to Jan 6, 2018. Then I tried the recovery steps to install mac os X lion but I got the exact same error message.
I copied and pasted the command...here's the error in Terminal:
date: bind: Permission denied
date: settimeofday (timeval): Operation not permitted
My Mac came with Mac OSX Lion installed, it's a iMac 27-inch, Mid 2011. I foolishly upgraded to macOS High Sierra without first doing a time machine backup and now I can't revert the operating system. Since upgrading to High Sierra my machine has been incredibly slow and I have a few applications that are incompatible with High Sierra.
I am folowing the instructions in the article you cited. I have to erase my harddrive each time because restoring Mac OSX Lion isn't even a choice, there is an error message that says something to the effect that there is a newer version of the OS installed on this harddrive so it can't be loaded. I erase teh harddrive using dis utilities, then back to installing Mac OS X Lion. It starts the installation process, then errors out with the error message "Can't download the additional components needed to install OS X". I have tried this three times now!
I appreciate your help.
The date command didn’t work in Terminal. I tried reinstalling the OS anyway but got the same error, again. Should I send the logs to Apple and ask for help, or take my Mac in to an Apple store?
