I could choose between the $10 full version of Trim Enabler or Chameleon SSD Optimizer, a shareware utility that has received positive reviews and supports OS X 10.7 Lion and later. (I have the same problem with OS X 10.4 Tiger on my Power Mac G5 Dual – and it works perfectly in OS X 10.5 Leopard.)Īfter failing with some online instructions for using Terminal to enable TRIM in OS X 10.9. One drawback of using OS X 10.6 with my 1600 x 1200 pixel display in vertical mode is that Snow Leopard won’t let me rotate the image to match the orientation of the display. Otherwise it’s always running on my Mac mini in the home office. I don’t often use Snow Leopard on this MacBook, but it’s there if I need it in the field. As with the Mac mini, I used the free OS X 10.6.8-only version of Trim Enabler on the Snow Leopard partition.

Enabling TRIMĪpple doesn’t support TRIM on most third-party SSDs unless you’re using the trimforce command in OS X 10.10.4 Yosemite or later – and I’m not.

I used SuperDuper! to clone each bootable partition to the SSD. I have OS X 10.6 Snow Leopard, 10.9 Mavericks, and work files on three partitions on the hard drive, and I pretty much duplicated that on the SSD, although with less room for Snow Leopard and more for Mavericks and work files. This replaces a 512 MB WD Scorpio Black, a 7200 rpm drive that has performed nicely for years – but the SSD in the Mac mini spoiled me. This time I put a 480 GB Crucial SSD into my Late 2008 Aluminum MacBook (also 2.0 GHz) for $110! Last year I put a 256 GB Samsung SSD in my 2. I can’t believe how affordable SSDs have become.
