Can not install OS X error...

Hi everyone, you all know by now that you need to adjust date to fix this but what really works is to adjust the date to mid 2017. It won't work if you adjust to current date.

Try an El Capitan install but before go to utilities once booted in the installer and then go in terminal and change the date to mid 2017. That should work.

I had the same problem with a MacBook Pro 5, 1 late 2008 vintage that is supposed to be able to run El Capitan. In fact it was running El Capitan before I erased the disk and tried to do a clean installation using MacOS Recovery.

I tried every trick that everyone has posted herein and NOTHING worked. If I downloaded and tried to install, got the "OS X could not be installed on this computer" error. If I changed the system date and tried to download the installer, I got an immediate error message that would not let me download the installer.

Called Apple support - they referenced all the tricks I had tried then offered that perhaps som 3rd party repair shop might be able to help at some cost.

Finally, I happened to have a Snow Leopard DVD. That installed OK. Machine is functioning albeit with a 2010 vintage OS. Now I can access Apple Store and my purchase history. I have installers there for everything from Snow Leopard forward. Ah, maybe a path to success. Downloaded El Capitan installer from the store. You guessed it - same crash and burn. And, of course, I don't have a functioning Snow Leopard any more. OK, reinstalled Snow Leopard and tried the Yosemite installer. Low and behold, that work. OK - not where I wanted to be - but at least I have a functional MacBook Pro running Yosemite. Beats having a brick, which where I was when I started this journey

command R > Utilities > Terminal > Type the following "date 0101124517"

date mmddHHMMyy

Replace the letters after "date" with numbers, as follows:

mm = Numeric month, a number from 1 to 12.

dd = Day, a number from 1 to 31.

HH = Hour, a number from 0 to 23.

MM = Minutes, a number from 0 to 59.

yy = Year in abbreviated form (e.g., 89 for 1989, 06 for 2006).

For example, to set the date time to March 10, 2016 18:05, the command entered would be:

date 0310180516

Still in the middle of install but I tried a date of 06 06 2016 and I seem to have gotten over that hurdle. Install seems to be progressing, although slowly. But better than not at all! Thanks!

I am working with a MacBook Air 2010 that already had El Capitan installed. I tried to do a fresh install because the storage was all taken up by Other. When I attempt to reinstall El Capitan I am prompted with the "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 have corrected the date in the terminal window mentioned in other strings of this problem.

I'm having the same problem... I'm trying for days to install the El Capitan and always appear that message If i Try to do it with a flash drive, when I try to download from the Apple Servers directly appear Service not available... I'm already quitting for a solution on this

How to Upgrade to Catalina

I am having same issue with 2008 Mac desktop. I go to Utilites, but don't see anywhere to change the date.

Where do I adjust the date? I see now where to do that. Thanks.

I will try that. Thank you!

Thanks for your support, this save my Day!
