I'm planning on upgrading to Yosemite from Mavericks on a Mid-2010 MBP 15" with a Samsung 840 PRO drive as the primary drive. I have TRIM disabled! The process I want to use is as follows so I'm just looking for a validation please!
Make sure Time Machine backup is current and good. I'll restore a single file to verify.
Verify TRIM disabled via System Report. Shows "TRIM Support: No"
Download installer from App Store and run upgrade in place.
Once done, reboot.
If all is well:
disable signed kernel extensions.
Install TRIM Enabler
Should be done.
Are there any problems with this methodology that I should be aware of?
Is there a significant advantage to a clean install versus upgrade in place? I know there is for Windows, but I've upgraded this system twice now with no problems.
Thanks in advance for the advice.
