Prohibitory symbol after fresh install on new SSD
Hi,
A few months ago my original HD failed (MacBook Pro (13-inch, Mid 2012)).
I decided to replace it myself with a SSD instead.
the thing is, on every boot up, I get the Prohibitory symbol for a few seconds up to hours sometimes, but once boot up is done - everything works perfectly.
tried replacing the SSD drive 3 times now - the same result after every fresh installation from internet recovery.
currently using SanDisk Ultra II 240GB.
Any suggestions ?
Thanks!
MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11.4)
