Mac Pro :: Trim Support Coming In OSX - Core I7 Processor?
Jun 14, 2010
Let's hope this happens for Mac Pro's as well.Here's the story on AppleInsider...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.

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.

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?
Info:
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.4)

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?

What is the significance of the Mac OS X 10.6 not having trim support for SSD drives? I was looking at Crucial's C300 drives, but then I read about trim support being really important.

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

i'm planning to buy a macbook as soon as they appear with Core i5 processors, and since i want teh fastest most reliable experience possible, im also getting an SSD.After using a Solid State Disk with my windows xp machine, i've realized that without TRIM, write performance degrades considerably.This leads me to ask two questions, and any help is greatly appreciated:1. Will this SSD work if i format it as a mac drive?256GB Samsung SSD - its gotten good reviews off amazon, but i wana ask the experts (macrumors community

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.

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

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

I have a PowerBook G4 15" Laptop and it's recently started making a buzzing noise. It drives me crazy! The noise seems to come from the processor and happens whenever I'm scrolling through web pages, hovering over my dock, launching applications or pretty much whenever the computer is doing anything.
I've googled the issue and found it to be quite common, even being some posts on this forum. Here's the best info I've found so far:
"The squeaking is actually the processor going into Nap mode, and has been noticed on a number of G4 and G5 models. To save power when the processor has a little bit of idle time, it essentially turns itself off. What is happening when it's squeaking like this is it is alternating very rapidly between going in and out of Napping as the processor waits for more things to do. I've noticed that it happens most often during an active SSL connection; an https:// connection, Software Update, checking E-mail on a secure server, or any other secure connections can make this squeaking noise. There are many other ways to produce it too, such as scrolling through a web page or some other more graphic-intensive process.
If you want to check and/or get rid of it, you can download the CHUD tools (part of Apple's Developer Tools, and also available separately). The Processor preference pane (formerly called Hardware) will let you disable Napping, after which point the squeaking should go away. The squeaking also goes away if you reduce processor speed by turning Energy Saver processor performance down to Reduced. However, I'd recommend that you leave Napping enabled (to reduce heat output and increase battery life), so leave it in the default state."
I've downloaded the CHUD tools program and turned off Nap mode, I think. But it still makes the noises! I cannot figure out how to reduce processor speed. So frustrating. Anyone have any advice?

You can currently get mac pro's in quad or octo core. The quad core models have one processor. Is it possible to buy a quad core today, and say 6 months from now, (if you can find the parts) add the 2nd processor? Is there a good place to find parts like that?

I looked in iStat Pro, at then saw that Safari was eating up one entire core of my processor. I am running one window with 3 tabs, another web archive, another Google search, a Google Image search, a window with a Youtube HD video running+a tab with a Google Video search. Is this to be expected with this much running? I am using Spaces.

Apple keep telling me I need to update to icloud but I'm not sure if Lion will work on my Mac. I've upgraded to snow leopard which seems to have knackered my .me or .mac account (whatever it's called now), so I don't seem to have any option but to upgrade to Lion if I every want to see my emails again. Apple say I must have a Intel Core 2 processor for Lion to work. at least I think that's what they say. I have a mac book pro, 2006 with an 2.16 GHz Intel Core Duo processor, can I update to Lion?

Additional details on Apple's just-announced iPad continue to trickle out, with iPhone OS 3.2 being iPad-only for the time being, evidence of camera support in the software development kit, and the details behind its LED backlit screen with "IPS technology."
iPhone OS 3.2 hints at camera support, is iPad-only
Though the iPad, introduced by Apple Wednesday, does not include a camera, the iPhone OS 3.2 SDK "simulator" for creating software hints the shipping product could support a camera in some fashion. One developer told AppleInsider that the native Contacts application offers the option to take a photo, in addition to choosing an existing one.
The option could be a sign that the shipping product could support a camera, perhaps through an external attachment to the iPad's 30-pin connector port. Or, it could just be something carried over from the iPhone, which does have an integrated camera.
Currently, the iPhone OS 3.2 SDK simulator reportedly contains only two applications: Settings and Contacts. It also has added rich text support in the UITextInput that allows different fonts, sizes and more. The iPhone OS 3.2 SDK also allows video output to an external display through a dock connector.
In addition, an update to the iPhone developers Web site has revealed the new version, iPhone OS 3.2, is, for the moment, iPad-only."Note: iPhone OS 3.2 does not support iPhone and iPod touch devices," the document states. "It only runs on iPad."The reveal of iPhone OS 3.2 confirms a report from earlier this week when an analytics firm revealed it had spotted 50 suspected iPads running the unreleased version of Apple's mobile operating system.pple's custom A4 processor pictured
Moments after Apple revealed the iPad would be powered by its custom A4 processor, iFixit provided an image of the internal component. The solutions provider said the A4 processor in Apple's video was manufactured during the last week of September 2009.It also noted that ARM has had a "secret" licensee for years that is likely Apple and P.A. Semi, the fabless chip designer it purchased for $278 million in 2008. AppleInsider first reported in 2008 that Apple has licensed the ARM architecture for years.
When the iPad is released in the next two months, you can be sure iFixit will have a peek inside the device.In-plane switching (IPS) LCD and other tidbitsApple touted Wednesday that its new iPad tablet device features an LCD screen with IPS technology, stating that it displays pictures that are "remarkably crisp and vivid" on its 9.7-inch LED-backlit screen. IPS technology was developed by Hitachi in 1996 to improve viewing angles and color reproductions on screens.
The iPad does not support the unique 1700Mhz spectrum utilized by the T-Mobile 3G network in the U.S. So although the hardware is unlocked and could theoretically access T-Mobile's EDGE network, 3G connectivity will not be an option anywhere but AT&T in the U.S.Much like the iPhone and iPod touch, the iPad does not have support for Adobe Flash. In fact, during Wednesday's keynote presentation, CEO Steve Jobs pulled up a Web site that had Flash embedded, and the missing plug-in icon was prominently displayed.
Quashing rumors that led up to Wednesday's event, the iPad also does not offer multi-tasking support for third-party applications.

With the Introduction of Civilization V for the Mac and its huge need for power. Now i'm not gonna attempt to try to play this game. But I downloaded Ship Simulator Extreme on my windows partition. Now on Steam it has the system requirements.
OS: Windows XP (Min. service pack 2), Windows Vista or Windows 7. 32 and 64 bits OS supported
Processor: 3 Ghz P4 Intel or AMD equivalent processor
Memory: 2GB (Windows XP) or 3GB (Vista or Windows 7)
Hard Disk Space: 3.5 GB
Video Card: Geforce 8800GT or ATI Radeon 4850 with 256MB ram (At least Shader model 3.0)
Sound: DirectX compatible
DirectX�: 9.0c
I have a MacBook Aluminium, Intel Core 2 Due 2.0GHz with 2GB Ram and NVIDIA 9400M. The game plays incredibly slowly and keeps jumping, like the refresh rate is so slow. I have downloaded the latest driver from NVIDIA but still it plays slow. Is my problem here the lack of RAM and I have a dual core processor which is above the requirements? I thought the good video card and processor would be enough? A lot of games seem to have minimum requirements much more than my mac, its not ever that old and seems outdated already.

My brother has the first generation of the iMacs that has a Core duo processor (not Core 2 Duo). Will snow leopard work on it? On Apples site, it says that you need a Intel processor to run Snow leopard, but then below it says you need a 64bit processor which is what he doesn't have.
