I have a MacBook Pro Mid 2012 that I want to try and upgrade to a Samsung EVO 860 SSD. Did the Time Machine backup, plugged in SSD and did a recovery install onto the SSD with the computer. Logged in and the computer was running smooth and fast with no issues.
So, I went into System Preferences and assigned the SSD as the startup drive and restarted the computer. Booted up no issue.
Then, turned off computer, removed the HDD and installed the SSD, turned on computer and everything is slow and sluggish and I get the spinning pinwheel repeatedly for any click. Noticed when the computer boots up it starts, then puts up the circle with the slash line through it (assume it was looking for original HDD which it shouldn't be because I assigned it to the new SSD) and then continues to load up the new SSD OS.
Really confused here. Help?
