Available as a free download to registrants of the annual Apple developer program, the seed has no known issues.Īpple continues to ask testers to focus their coding efforts on five key areas of the operating system: Wi-Fi, Graphics, Wake from Sleep, PDF Viewing and Accessibility, as well as Mobile Device Management. The fourth beta of OS X 10.8.5 Mountain Lion is out on the Apple Dev Center. As for getting the OS If you’ve accessed it from the Apps Store you can get it again, If not you can go to Apples downloads and heres a bit more on how to install it. High Serra and Mojave introduce a newer file system which does not work well on SATA based SSHD or SSD drives. I strongly recommend you only go to Sierra 10.12.x. OK, thats the hardware side, now lets talk about upgrading the OS. More RAM will help your system deal with large files and applications. The last action is to max out the RAM to 16 GB if you can. The original cable is not rated for the higher I/O flows from either the SSHD or SSD MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable I also place a strip of electricians tape on the uppercase where the cable crosses over to help protect it and you don’t want to bend the cable sharply as that can damage it, you want a smooth arcs.
You do want to replace the HD SATA cable when you replace the drive. But! do keep in mind you need to leave 1/3 to 1/4 of the drive free depending on the size (the smaller SSD’s need more free space).
As for what drive to get you could go with a SSHD hybrid drive which gives you the zing from the SSD cache and yet the deeper storage of a traditional HDD. The other direction is just replace the drive and then Migrate your stuff from the old drive to the new drive. This will take some time and you do want to make a full backup before you start this.
Over time HDD’s get frag’ed this is where a given file is broken up in to many parts so it slows to loading and saving of the file. If your current HDD is getting full or is slow then you could clean off the junk making space and you could also run a defragmenter to speed up your drive.
You raise a few different directions here lets see if we can put this in a more logical order…
