I’ve recently tried to reset an old MacBook Pro 2011 so I can sell it and after going through steps to get it up and working again I’m stuck on the part about re installing the Mac OS as it’s been erased I have no os I go to reinstall the os and get errors I’ve tried the date change and still nothing is there any way I can get it back to working order?
Earlier Mac models
Try booting into Internet Recovery Mode using Command + Option + R to attempt to access the online macOS 10.13 High Sierra installer.
If you are able to access the online High Sierra installer, then you will likely need to use Fix #3 in the following article since Apple has broken that online installer:
If you cannot access the High Sierra installer, then what are the exact errors you are getting when trying to reinstall Lion?
If you have changed the date & time to something other than the current date & time, then you will need to reset the date & time to the current date & time in order to access the online High Sierra installer.
If you have trouble with Internet Recovery Mode, then you may need to create & use a bootable macOS USB installer, but you will need access to another compatible working Mac. You generally need a Mac from 2007 to mid-2018 in order to create a bootable macOS USB installer for your 2011 Mac (macOS 10.11 or 10.13 depending on the model of the other Mac).
To confirm compatibility of the other Mac with a specific OS, you can use the information in the following article since the models I listed are just generalizations:

Yes, you cannot install to the installer USB, is Macintosh HD not a choice?
Clicked on Macintosh and now says installing Mac OS X
That's good! That means its working! Now it should work perfectly when it finished.
Nice help, thanks! :) 👍
