No secret, I help friends\u00a0update the performance of their old Macs. Aside from bumping RAM or upgrade operating systems, I will often recommend the\u00a0replacement of a\u00a0spinning hard drive\u00a0with a modern solid state drive (SSD). Using apps like SuperDuper or CarbonCopyCloner, its easy to back up their data and then install a fresh system on a new SSD, which helps to recreate the recovery partition.<\/p>\n
After migrating user accounts and data back to the new drive, I like to enable TRIM, if the SSD supports it and most do. To do so, open Terminal.app and paste in the following line:<\/p>\n
You’ll be warned that data loss could occur, but\u00a0I have yet to find an issue with dataloss on any SSDs I’ve done this with. Press y to continue. That’s it.<\/p>\n If you want to see\u00a0the TRIM status for your boot drive, execute the following Terminal command:<\/p>\n Hopefully yours says “TRIM Support: Yes”. Or, if you’d prefer to view the status in a Mac application,\u00a0you could select the Apple icon in the upper left corner of your screen, choose About This Mac->System Report…, and then choose SATA\/SATA Express and scroll down until you see TRIM Support on the right hand pane (note: you also might need to select the drive you’re curious about in the upper right hand pane).<\/p>\n ** Update 11-9-2020 **<\/p>\n For those running NVMe drives, this Terminal command should show if TRIM support exists:<\/p>\n And responding to first comment, below, if your drive responds to this code with “TRIM Support: Yes”, we know trim force worked based on an Apple engineer’s response<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" No secret, I help friends\u00a0update the performance of their old Macs.
