MacBook Pro :: Enabling TRIM On Non Apple SSD?
Apr 29, 2012
I own a MBP 13" early 2011 model  I just recently Upgraded my 320GB hard drive to an intel 520 SSD (240gb). After setting up lion 10.7.3 i realized that TRIM was not enabled by default. after searching around I found a way to enable it. However, I've also read that alot of sandforce 2281 controllers have their own form of garbage collection. intel uses some custom firmware they written so would it be benificial if i enable trim or not?
Info:
MacBook Pro, Mac OS X (10.7)

I purchased an Intel 34nm 160GB SSD 12 months ago to install in my MBP 13". It has been an excellent drive, however, started to significantly slow down over the last few months. The only way I was able to recover to original speeds was by formatting the entire drive as a windows drive and running the Intel SSD Toolbox app in Win 7 (manual trim command).Finally I reinstalled OSX and voila drive was as fast as when I initially purchased it.Either Intel needs to release a OSX compatible toolbox app or Apple needs to build the functionality into OSX.I know this has been a topic before but thought I'd share my experience.

I'm converting stuff with Handbrake using Apple TV preset for my iPhone 4 and 1G Apple TV. Works great.
However, what app for Mac is there to then trim the video? I want to trim the start and end as sometimes ends up being about 15mins, and I never watch the whole credits on end.
Preferably free or low cost. I have iMovie 09 but think this will re-encode the file? I just want to trim it.

Apple may be laying the foundation for TRIM support in future Macs, a technology that should allow their solid state flash drives to maintain optimal performance throughout the life span of the systems.The Mac maker's most recent 13-inch MacBook Pros display an option for TRIM support in their system profilers on SSD-equipped models, one which isn't present in either the second-generation unibody 15-inch MacBook Pros or the latest refresh sporting Intel's Core i5 and Core i7 processors.TRIM is essentially a command that lets operating systems like Mac OS X inform SSDs of which blocks of pre-written data are no longer in use, allowing them to be wiped clean internally.

How long/soon do you guys think we have to wait till OS X gets TRIM support? Do you think we will get it in 10.6.5 or do you think we will have to wait till 10.7?

I recently updated to a Macbook pro 15" with 1TB SSD, should I use TRIM enabler? I have read conflicting information online, and am unsure if I should do this. What are the advantages? What are the dis-advantages? What is the process?

I've spent the best part of the day researching SSD drives, I'm wanting to pop one in my MBP.I've been looking at the OCZ Vertex and also the Intel X-25M Gen 2.I've set my heart on getting the OCZ but after spending a good hour on their forums, it seems that (like all other drives) there isn't a 'wiper' tool available for OSX.Should this affect my decision? No-one knows if Snow Leopard will support TRIM and I don't want to left with a drive that has lost most of it's umph after a few weeks.I don't claim to know all the details of TRIM (I'm a mere-mortal wanting faster performance), so please feel free to put my mind at ease

First post so I apologize for any rules I may be breaking. A lot of discussion on this forum has centered around SSD's and their use. From what I have gathered, the price is quite high, but the speed is impressive. I am going to university next year and am looking for a new laptop. I have used Windows all my life and don't have anything that really requires OSX (graphics applications, etc). However, I like the design of the MBP and want something high quality that will last me 4 years. The SSD's are looking pretty appealing for the sheer speed, but OSX doesn't support TRIM, which could affect future speeds.

So after knowing nothing about SSDs I finally ordered this one for my 2010 i5 MBP.

I have searched and I know Snow Leopard doesn't support TRIM yet but I was wondering if I use boot camp and install Windows 7 won't TRIM be available then? I can install all the software that came with the SSD under Windows. So my question is if I do that will the Trim feature only work on the Windows 7 partition or the entire drive?

It looks like OS X supports TRIM, but still says that my SSD doesn't support it. How stupid is that?

I�m not quite sure if this has been mentioned before, but I was wondering if the TRIM command would be functional if I was to run Windows 7 via VMware or bootcamp?
I know Snow Leopard does not support TRIM and Windows 7 does, so I was hoping as a workaround to this issue, I would run windows 7 on vmware and maybe reap the benefits of TRIM support in Windows 7? I do on occasion use Windows 7 via VMware, so I'm not only considering installing it for just the TRIM command function.

I have installed a Seagate 1 TB hybrid drive (8gb flash, 2.5", 5400 rpm) in my Mac 8.1 (early 2011 MBP, 16 gb memory), which runs the Yosemite OS.  After reading about SSD's and Trim, and the negative effect of Trim disabling upon SSDs after several months, I am wondering if there is a need to enable/disable Trim upon a THD (traditional hd drv) which has 8gb flash for quick booting.?

So I just installed an Intel x25-M into the hard drive bay of my MBP 15" i7, and put the stock HDD into the optibay.Installed OSX onto the SSD, wiped the HDD clean, everything seems to be working perfectly.Disabled SMS, disabled hibernation, all fine. I would like to enable noatime, but for the life of me can't figure out what I'm doing wrong.
After I restart, I check the status of naotime in terminal (as directed) but all I see is "hfs, local, journaled" and there is no indication of noatime.

Could someone check in their System Profiler -> Serial-ATATRIM would be really useful during the lifetime of the flash drive.

Whenever the MBP refresh happens I intend to upgrade the stock HDD to a 7200rpm 500GB HDD or, less likely, to an SSD. An SSD had been my first option until I learned about SSD performance degradation and the lack of TRIM support in OSX. I was ready to stomach the massive SSD price premium, but the lack of TRIM would most likely rule it out completely for me. And I recall reading something about the MBP hardware connection (perhaps the the SATA connector) having a slight bottleneck compared to SSD-equipped Windows machines; so some of the top of the line SSDs won't be able to max out their transfer rates on OSX. (This is the best, not so informative, link I can find now referring to that impaired performance: http://macperformanceguide.com/Revie...tml#Single_MBP) With these performance issues, I've become perplexed why SSDs are popular amongst some Apple users

What is the best way to setup effective TRIM for a newly installed SanDisk Ultra Plus 256 GB (old version) drive on a mid 2010 MacBook Pro 6,2 with 8 GB RAM and running just installed Yosemite OSs 10.10.1? The new operating system is not referenced by SanDisk.Â

System: Silver Macbook
OS X Ver.: Leopard
Backlit Keyboard?: No
Essentially my problem is that I'm unable to set new shortcuts for the F5 and F6 keys for my Silver Macbook. Since it doesn't have a backlit keyboard, there's no function for F5 and F6. I'd like to make them go to shortcuts such as "Show Desktop" and "Spaces", both of which are supported under the "Keyboard Shortcuts" Tab of "Keyboard & Mouse". So, I have them configured to match up to F5 and F6, but they do not activate the corresponding function when pressed.
I have the "Use function keys as standard function keys" checkmark unset:I apologize for the fairly small problem...I just really want to free up those two keys! I appreciate any response.

I have an Unibody MacBook. I've experienced that under OS X "Tap to Click" function of the trackpad stops to work after "some" usage. Then I go to System Preferences, disable the feature, reenable it and it starts working again. OS X is updated and firmware updates are all installed.

Before I formatted and reinstalled Lion on my MBP, I could select a window by tapping on its top bar and drag it using single finger on my trackpad. After reinstalling it, I am unable to do so. I have investigated the trackpad features in System Preferences, but it shows only the three-finger drag option. How do I get to select + drag a windown using single tap.

I need to erase the soundtrack from a movie, using the QT X player in Snow Leopard. Can this be done, without using the QT 7 player? Also, how can I remove a video part in the middle of a movie, using the QT X player? Apparently, I can only remove the start and end parts, using the trim option (command-T).

Since AirPrint is only working for select printers right now, it doesn't work for many people. I have heard of ways to workaround this.
First I have heard of adding certain files into the Mac's file system, I hear this is tricky and doesn't work for everyone. Another way I have heard is through applications such as Printopia. I know there are other applications that are free but I have heard some bad things, also I don't want to pay $10 for Printopia.
