Trim Enabler Beta 5
Jan 16th
So I finally got a couple of hours to work on Trim Enabler, and the result is Beta 5.
I have rewritten alot of the code from scratch because it was bad design, and I have used some tricks I learned while making Kext Drop.
Beta 5 features are:
If people can test and confirm this version works well (especially you who experienced crasches with b4) I will conclude testing and release it as final 2.0 version.
about 7970 and Mac Pro
Jan 14th
7970 is officially released (for PC) and since a new Mac Pro is imminent, people are wondering if (and when!) we will finally see a new Mac Pro launch with a brand new GPU inside it. There is also alot of questions whether 7970 will work in older Mac Pro’s, either Apple card or PC one through flashing. Here’s my thoughts on it.
There are references of Radeon 7900 found (by netkas) in beta 10.7.3 drivers. They seem to be early addition of new support (addition of “tahiti” identifiers function calls), not enough to run cards it seems. The identifiers are of desktop card models, so they don’t refer to iMac mobility cards. That could mean that Apple might be testing card in 2012 Mac Pro, getting ready for release.
No doubt Apple will label the cards as “2010/2012 Mac Pro compatible only” in the Apple Store, but there is really nothing technical that prevents these cards from being used in older Mac Pro’s. They will probably be bottlenecked in the 2006 and 2007 Mac Pro with PCIe 16x though.
We don’t know how 7000 series will behave in terms of EFI though. ATI (AMD) has so far released all their cards with EBC (EFI 32bit and 64 bit, aka also works in old Mac Pro’s). As for converting PC cards, PC 4870 and 5870 had to be flashed to boot at all, 6870 suddenly started booting without flash (but no bootscreen). We’ll just have to see how that plays out.
So when can someone be certain that support for 7000 series will be implemented in OSX? Well that’s easy. In time for it being released in Mac computers ofc. I strongly believe Mac Pro 2012 will use 7000 series, mainly because a. It’s released and b. 6000 series are not manufactured anymore. The 7970 is a insanely powerful card, and has great power management. Apple has no reason not to choose it. If it releases, it will probably be an upgrade/BTO, and the 7870 would probably be the base card.
I will be preparing some good resources for the site in regards to flashing in time for the debut of the 7970 on the Mac Pro.
updates
Jan 6th
New menu section – Software
Added page about Kext Drop (under construction)
Finally added page about Trim Enabler
I’ve had many emails and comments about how trim works in OSX and “do I need it for SSD xxxx”, so I’m working on a “Trim Guide” for OSX that will hopefully clear things up!
Happy new year!
Jan 2nd
2012 will the most exciting year yet for groths.org!
Keep eyes out for new Trim Enabler version in the following weeks
new app – Kext Drop
Dec 27th
So when developing Trim Enabler I have been juggling back and forth with kexts and I often find that the kext installers out there are either cluttered with features I don’t use or are prone to crashing. So I decided to make my own Kext installer!
You can find it at the Software section:
Download Kext Drop
Trim Enabler 2.0 Beta 4
Dec 6th
This should fix the problem with app crashing on startup.
Next step is to have the switch and status text update automatically without having to use Update button after each action…

And a big thanks to all donaters and supporters!

AMD Radeon HD 7000 in a month
Dec 1st
AMD Radeon HD 7970 is announced today to be released in Januari.
Guess we might be seeing a Mac Pro 2012 with brand new GPU’s?
With almost 50% smaller die size, we can expect close to double performance versus 6970…
Trim Enabler 2.0 Beta 2
Nov 17th
UPDATED: see bottom
Still some stuff I need to work on, so still Beta
Changes:
- Rewritten from AppleScript to 100% Objective-C
- Features new S.M.A.R.T tool to learn about your drive’s health
- New icon, courtesy of vegrafik
- No longer installs an old driver, instead patches your current*
*Previous Trim Enabler never was a longterm solution, although a label in the app said “Only for Snow Leopard” I made a claim on this blog that it would not be any problems to use it in Lion. Well as some users have pointed out, using an older driver could lead to slower speeds and I admit I did take the advice the wrong way and chose to ignore it. My apologies to those persons and the users for my ignorance and for taking so long to fix the issue.
- If you have patched in Lion with previous Trim Enabler (1.1 or 1.2, not the 2.0 Beta 1) then I suggest you proceed with following steps to update your driver to the latest version:
- Type in terminal: diskutil mount ‘Recovery HD’
- Open Recovery HD in Finder
- Navigate to BaseSystem.dmg (it is hidden, so you will need to set Finder to show hidden files), open/mount it
- Open BaseSystem in Finder, navigate to System/Library/Extensions/IOAHCIFamily.kext
- Use Kexthelper app to install that kext back to your system
- Use Trim Enabler 2.0
- Slider button and status text does not update properly on patch/unpatch, that is why there is a Update button, press it 3 seconds after you have activated or deactivated the switch to properly update status
Should not be too hard to fix, but I am drowning in school work so that’s why I’m releasing it as Beta 2. It will also be useful to gather feedback for a final v.2.0 release, I can only test so much with one computer.
Should be compatible with Snow Leopard 10.6.8 or Lion.
Please report back with your experience.
