Mac Pro (Classic) - USB 3.0 Solutions

A while ago, I started participating in a discussion thread on the Mac Rumors Forum regarding USB 3.0 upgrade solutions for the Classic Mac Pro (5,1 and below - Pre 2013).

Here is post #1 which presents the best available solutions at this time.  I'm posting the link (rather than copying it) since it stays pretty much up to date.

What is the state of USB 3.0 on Mac Pro?

That's it for now...

How to enable trim for SSDs in the OS X Terminal (OS X Mavericks) - 10.9.x

NOTE: These methods (except Trim Enabler ) stopped working with the 10.9.4 update. Trim Enabler still works as expected. I will refresh this post when the situation changes. I expect an update to both Chameleon SSD Optimizer and the terminal commands will be coming shortly.

Many people are having issues trying to enable trim for their non-Apple SSDs since the release of Mavericks. It's pretty straight forward though, you can either download and install Trim Enabler, download and install Chameleon SSD Optimizer, or open up a command line terminal and paste the following code.First:

sudo perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00{1,20})[^\x00]{9}(\x00{1,20}\x54)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage


sudo touch /System/Library/Extensions/

I personally like the Chameleon SSD Optimizer because once you run it, it doesn't load anything up on startup ever. I like that. Many people like Trim Enabler specifically because it does load a helper too on every reboot that stays in your upper tool bar. If Trim becomes disabled for any reason, it will instantly notify you and prompt you to re-enable Trim.I've not personally had a problem where Trim gets disabled (except after an OS X system update, which is to be expected). However if you are setting up a system for an uninformed user, I would recommend Trim Enabler.Also, don't be a cheapskate! If you use one of the Apps rather than the terminal command, please donate something to the developer or make a purchase where applicable. We need them to keep on developing great tools like these.-OUT
