I have been reimaging a few Macbook Pros and have been experiencing issues with upgrading from OS 10.6.8. I am unable to update to OS Sierra or El Capitan without upgrading to 10.7 which I haven’t been able to upgrade to or download successfully. Has anyone else come across this as well?
If you truly are coming from Snow Leopard, you might be better off with a nuke/pave scenario.
One thing to note, your Macs must be 2010 and newer for Sierra.
You are coming from a long way back. I would take the erase and clean install path Will suggested. Just make sure you meet the minimum system requirements.
I actually did the clean erase (nuke/pave) on one system and when I
restored the OS it restored to Sierra. Thanks for the help guys.
