Worked like a charm! Took a little more than 5 mins, but who’s counting? My old battery had more than 3,300 days on it and although it still worked fine, after almost 10 years of service, probably better to go ahead and replace it. Thanks for the instructions!
My MBP 13 inch, 2009 was working perfectly, just needed more space. I replaced my 160GB drive with a Toshiba 1TB and used this procedure. Everything worked perfectly! One thing I did first was to connect the new drive with an external chassis and initialized it. I then booted into Recovery mode “Control-R” and chose Restore from Diskutility, choosing my new drive as the Target. After about an hour, the new drive was ready. Then I restarted, ran Sys Prefs | Startup Disk and chose the new (External) drive as the boot disk and restarted again. This makes the new disk “Bootable”. Once complete, I ran Sys Prefs | Startup Disk again and selected the Internal drive. After another restart, I shut the system down and replaced the drive. It booted without any problems and my system is now the same with a bigger drive. I decided to mothball my old drive, just in case there is a problem with the new drive in the near future. Thank you for the tutorial!
