Currently I am restoring backup, but I'd rather try again if there is still a working solution for me.ĭoes apple do same thing as ios versions (we are not able to downgrade once they stop signing previous iOS versions)? Or there is still a light at the end of this tunnel, and is there any possibility for me to downgrade my sierra to another os x which works more fluent on my "old" mac? I was forced to reinstall os x by entering cmd R, I expected to have the factory default osx here, but I only saw Sierra os x. I tried erasing hard disk, then trying to start from DVD (both original installation Dvd and Snow Leopard OS X) but I got a kernel panic. The reason for doing that is my 2011 MBPro became a slow machine in every little situation. Hi all, as stated on title, I would like to downgrade from OS X Sierra to an earlier OS X.īefore writing this post I have tried to reach answers on the web, no found though.
