High Sierra: $ sudo /Applications/Install\ macOS\ High\ Sierra.app /Contents/Resources /createinstallmedia -volume /Volumes/MyVolume Mojave: $ sudo /Applications/Install\ macOS\ Mojave.app /Contents/Resources /createinstallmedia -volume /Volumes/MyVolume Once the MacOS X upgrader is installer it is available as a command in your /Applications folder. Instead - once you've downloaded the upgrader, exit it, then head to the command-line terminal application to type a couple commands in the terminal. Instead you must divert the process by not running the upgrader after downloading it. Normally you go to the app store, tell it to download the MacOS X upgrader, and let it do its thing.
This is very easy, though requiring a slight deviation from the normal MacOS X upgrade instructions.
Afterwords you install MacOS X on the new SSD, and perform a User Migration to bring over your files from the old disk.įirst thing is to prepare a bootable flash drive with the MacOS X Installer. Basically you pop off the bottom cover, disconnect the battery, replace the RAM sticks, replace the hard disk, and optionally remove the DVD drive replacing it with a disk bracket containing another hard disk. Upgrading the 2012 MacBook ProĪs seen in the embedded videos, the process is very simple. With Final Cut Pro, the upgraded machine even rendered videos faster than it did before the upgrade. In one of the embedded videos, the presenter found Final Cut Pro to be very usable, but Premier Pro was almost unusable. Otherwise this older MacBook Pro handles even demanding software development tasks just fine. If your work requires a GPU - like, for video editing - you may be disappointed. The disadvantage is that you won't have the latest and greatest, with the key problem being a lesser grade of GPU. It was available with Core i5 and Core i7 CPU's, and of course the i7 is more powerful so pony up the extra bucks required for this machine. When selecting a 2012 MacBook Pro, strive for the Core i7 version.
My goal a couple years ago when setting up this machine was to have a reasonably powerful computer that will last for as long as possible and which I can repair as needed. Following the 2012 models Apple has made it progressively harder to open the machine and replace things. The 2012 MacBook Pro is the last model that was trivially easy to upgrade or repair. Overall faster performance - SSD is a ton faster than HDD's, meaning when the OS reads data or applications from disk that happens much faster.Faster app launch time - "lightning fast".Faster boot time - 15 seconds versus 1.5 minutes.
