Here, you’ll also see the negotiated SATA link speed. You can check if you have the MCP79 by going to the upper left hand corner Apple menu, choosing About This Mac, More Info, System Report and the SATA section. Even if you can’t get 6Gbps like modern machines, you’re still much better off with 3Gbps than 1.5Gbps if you have a choice. The bad combination might give you other issues as well. Those Macs will not work with their full 3Gbps link speed with a lot of current SSD’s, instead falling back to 1.5Gbps only. You need to be careful when choosing your brand, since many Macs built around 2007–2011 come with the buggy Nvidia MCP79 SATA controller. Just one catch: Not all SSDs will always work as fast as you’d want.
It makes a big difference in daily use for fairly low cost. To identify your exact model of Mac, go to .įirst of all: It’s worth it if your Mac is around five or six years old.Upgrading a 2009 (pre-Unibody) Mac mini 3,1 (Core 2 Duo 2.26GHz 4GB RAM) with a Crucial M500 SSD.Upgrading a 2008 White (pre-Unibody) Macbook 4,1 (Core 2 Duo 2.1GHz 1GB RAM) with a Kingston SSDNow V300 SSD and 4GB RAM.This is written after the following updates: If you're following the technique I've outlined, it's wise to try booting from the new external SSD before installing it internally, just to make sure the computer recognizes the drive as bootable.SSDs (solid-state drives) are much faster than old-school hard drives, making it possible to get a few more years of life out of an old, slow computer by upgrading it to a faster drive. That way, once you restart the reassembled computer, you can at least be sure that there's a drive with a bootable operating system available. then open up the computer and swap the drives.clone the operating system+user data from the internal HD to the external SSD using Disk Utility, SuperDuper! or Carbon Copy Cloner (you can also do a clean operating system install by downloading an installer from the App Store and installing it on the new drive).
attach the SSD as an external drive first through USB/FireWire/ Thunderbolt.What steps have you already taken? If you can give us a detailed list of the things you've already done, in order, it will be easier to determine where the problem is.Ī common technique to replace an internal boot HD with an SSD would be to: Of course, if the way you installed this SSD was to remove the previous internal HD and install the SSD in its place, without formatting the new SSD and installing a bootable operating system first, then there's no operating system or formatting utility at all. Unless the operating system on the old boot drive posts a dialog box offering to format the unrecognized drive, the computer doesn't "detect" anything because there isn't anything the operating system can speak to yet. A new internal drive normally ships unformatted.
