Trim For Mac Os X

Ever since the release of OS X 10.6.8, Apple has been selectively enabling the TRIM command for SSDs in OS X. This support continues on in OS X Mavericks, but as many have noted, it only seems to work for Apple SSDs by default. We’ll show you how you can enable TRIM across the board.

By default, Mac OS, unlike Windows, doesn't automatically enable the TRIM command for a self-installed SSD. (If your Mac comes with an SSD, TRIM will already be enabled.) (If your Mac comes with. Mac OS X is an operating system by Apple Inc. It is a conglomoration of NeXTSTEP, A/UX, and Mac OS 9. It is based off the unix kernel and provides compatibility with X11.

The size of the latest downloadable installation package is 61.1 MB. The bundle identifier for TRIM Enabler for Mac is Cindori.Trim-Enabler. This Mac application was originally developed by Oskar Groth. The most popular versions among TRIM Enabler for Mac users are 3.3, 3.2 and 2.2. You can run this program on Mac OS X 10.7 or later. Free trim enabler 3 download mac os x 10.8. System Tools downloads - TRIM Enabler by Oskar Groth and many more programs are available for instant and free download. Adding TRIM Support to OS X. First, make sure you've updated to at least Mac OS X 10.6.7, as Trim Enabler won't work on previous versions of OS X. Once you've updated to 10.6.7 and verified that.

What is TRIM?

The TRIM command is an important disk command for SSDs that keeps your flash memory appropriately cycled so that you can achieve faster read and write speeds, as well as a longer lifespan for your SSD. As such, TRIM support is not the trivial matter that some make it out to be (although certain manufacturers, such as Other World Computing, include firmware that eliminates the need for OS-level TRIM support).

How to Enable TRIM Via the OS X Terminal (Recommended)

In you have an SSD that supports TRIM, follow the below instructions to enable it in OS X Mavericks. Note: This involves the use of terminal commands, so proceed at your own risk.

First, enter the command found in this document in the Terminal app on your Mac (found in Applications/Utilities).

After entering this command, you’ll need to enter a second command:

sudo touch /System/Library/Extensions/

The above-linked document also contains some troubleshooting instructions, as well as details on how to disable TRIM support if necessary.

Using a Third Party Tool

If you don’t find success using the Terminal command to enable TRIM for your SSD, there are two third-party apps that can help you enable TRIM support. I recommend trying Chameleon SSD Optimizer first. If that doesn’t do the trick, you can try TRIM Enabler 3.0 or later for Mac. I don’t like to recommend third-party tools, as they often make system-level changes above and beyond those performed by the terminal command – and that may not be in your best interest long-term.

Verifying TRIM Support

To ensure that the command was successful, and that TRIM really is enabled on your SSD, click the Finder menu in the Menu bar, then navigate to About This Mac > More Info > System Report. Then, scroll to the SATA/SATA Express section, and select your SSD. You should see a section called TRIM

Note: In some cases, a restart may be required before TRIM shows as Enabled in the System Profiler. With Mavericks, not all SSDs will report TRIM support, but doing a benchmark both before and after the change should confirm that TRIM is functional.

Added Bonus: Thunderbolt TRIM Support!

As an added bonus in OS X Mountain Lion or later, including OS X Mavericks (I have not tested this in previous versions of OS X), raid can now also be enabled for SSDs hooked to your Mac through a Thunderbolt PCIe controller, such as the excellent Magma ExpressBox 3T! For more info on these devices, check out our complete review roundup of Thunderbolt PCIe controllers – perfect for Apple’s 2013 Mac Pro!

If you’re looking for an SSD to use in your Mac, I recommend checking out the OCZ Vector or the Sandisk Extreme. Also, make sure to check out the full range of affordable SSDs available on Amazon!

Software -

SRIM is a collection of software packages which calculate many features of the transport of ions in matter. Mac os lion for dvd release. Typical applications include:

·Ion Stopping and Range in Targets: Most aspects of the energy loss of ions in matter are calculated in SRIM, theStopping and Range of Ions in Matter. SRIM includes quick calculations which produce tables of stopping powers, range and straggling distributions for any ion at any energy in any elemental target. More elaborate calculations include targets with complex multi-layer configurations.

·Ion Implantation: Ion beams are used to modify samples by injecting atoms to change the target chemical and electronic properties. The ion beam also causes damage to solid targets by atom displacement. Most of the kinetic effect s associated with the physics of this kind of interactions are found in the SRIM package.

·Sputtering: The ion beam may knock out target atoms, a process called ion sputtering. The calculation of sputtering, by any ion at any energy, is included in the SRIM package.

·Ion Transmission: Ion beams can be followed through mixed gas/solid target layers, such as occurs in ionization chambers or in energy degrader blocks used to reduce ion beam energies.

·Ion Beam Therapy: Ion beams are widely used in medical therapy, especially in radiation oncology. Typical applications are included.

Science -

The science of ion beams goes back almost a century to the earliest explanations of radioactive particles transiting thin films (1904). The field is so rich that it is difficult for a non-expert to understand any of the current papers in the field. But basically, the stopping of ions in matter can not be calculated from first principles. Hidden in stopping theories are parameters which normalize calculated stopping powers to existing data. The 'Science' section of SRIM will review the basic theories of the stopping of ions in matter. Then some of the major parameters are reviewed and it will be shown how they are derived from experimental data. Examples are shell corrections, mean ionization potentials, the effective charge of ions and the Fermi velocity of solids.

Over 2000 papers have been published in the experimental stopping of ions in solids. Experimental measurements of stopping powers is a difficult task, and there is wide variation in the results. Plots will show how existing stopping calculations compare to experimental data from these papers. Since the stopping calculations are based in great part on theory, the interpolation of stopping powers between various ions and targets is often more accurate than individual measurements, especially for difficult targets.

Although this subject is more about the effects of energetic hadrons on terrestrial electronics than about ion beams, it is scientifically in a similar field (hadrons = protons, neutrons and pions, i.e. particles which respond to the nuclear force / strong interaction). The science and technology about cosmic ray induced soft fails was considered proprietary by IBM for more than 15 years. In 1996, a complete issue of the IBM Journal of Research and Development was devoted to reviewing this work. A summary of the issue, and the complete first article (the 15 year history of the development of the IBM scientific understanding of soft fails from radiation) is given at IBM J. R.& D.

The scientific history of this field is reviewed in detail. The field is not static because the technology of integrated circuits is still rapidly changing and the effects of cosmic rays on integrated circuits (ICs) show trends which are not well understood. The trends in the sensitivity of ICs to cosmic rays are reviewed for SRAMs, DRAMs and logic over the last 15 years.

Fundamental to any estimates of the fail rate of ICs is an understanding of the ambient flux of cosmic rays in the environment. As this flux has been investigated over the last 15 years, it has become fuzzier rather than more precise. Previous measurements of the ambient flux which were considered reliable have been shown to be suspect. New measurements rarely agree with past measurements. Recent reports of the flux of sea level cosmic ray hadrons vary by more than 10x, even though they were performed by highly competent scientists. The problem will probably be resolved by understanding that the immediate materials nearby an experiment can have significant effect on the measured flux. The field of the terrestrial flux of cosmic rays will be reviewed.
