OS X 10.7 Lion Adds TRIM Support, But Not For All

Posted on by

I just happened to upgrade the firmware on my Crucial C300 256GB SSD drive in my MacBook Pro (13″ Unibody, Late 2008) on the same day that I upgraded to OS X 10.7 Lion. In my previous post, I touched briefly on the fact that 10.7 in the renamed “System Information” app under the “Serial-ATA” section does not detect my SSD as having TRIM support.

This is one of the very top SSD models out there in terms of performance and size, and it’s been proven in multiple benchmarks (though with the C400 coming out, things are set to change once more); and has proven to be a popular choice for MacBook owners due to the large size and incredible performance even without TRIM in previous versions of OS X.

C300 Negotiated Link Speed on OS X

This is just a quick note for anyone using the most wonderful Crucial C300 on OS X.

If in the “System Profiler” (now renamed to the more apt “System Information” in OS X 10.7 Lion), you see:

Link Speed: 3 Gigabit

Negotiated Link Speed: 1.5 Gigabit

And are wondering where your remaining 1.5 (or 4.5 if you have a 6 Gbps SATA controller) gigabits went, then you need to upgrade the C300 to the latest firmware. This appears to be an issue with the 0002 firmware that is resolved in 0006. Unfortunately, this does not seem to make OS X 10.7 aware that the C300 supports TRIM.

Also a tip: if after upgrading to revision 0006, your OS X will hang at boot, re-run the upgrade. It won’t actually upgrade it again (and will finish instantly), but it appears to fix something important.

Recently (late November), Adobe finally got around to releasing an update to Flash Player for OS X that comes with the long-awaited hardware-based rendering of H.264-encoded videos. However, for those of us that use Chrome, there is no way to updated to the latest 10.2 beta of Flash; Chrome uses its own copy of Flash that comes built-in and cannot be externally updated. These steps below will guide you through the process of using Flash Player 10.2 with Google Chrome on OS X:

Software with a (Subtle) Sense of Humor

Every once in a while you come across something in a piece of software that makes you smile. In this case, it was trying to open a 60MB CHM file in BetterZip, the best OS X unzip utility out there. A lot of software out there tries too hard to be funny, and really doesn’t come across as such (I’m look at you, ImgBurn).

But here’s a very serious program that does some very serious stuff. It’s never cracked jokes at me before, and it’s been a dependable creature, all business thus far. But all work and no play makes Jack a very dull boy. And so that brings us to the sense of humor – image after the jump:

Hello and welcome to EasyBCD 2.0!!

It’s rather hard to believe, but EasyBCD 1.7.2 has been out for over 2 years now, and we’ve been working on Version 2.0 ever since. In that time, a lot has happened. Windows 7 has shipped, ext4fs is the new cool kid on the Linux block, GRUB2 is finally seeing some adoption, VHDs are the new wow, and everyone and their grandmother want a dual-boot between Windows 7 and Windows XP.

Worry not, we haven’t been sitting on our (not-so-proverbial) behinds this whole time. In fact, the entire NeoSmart team – developers, supporters, testers, and all – have been working around the clock to make EasyBCD 2.0 the biggest, coolest, greatest, and awesomest thing ever since the invention of the MBR. And now, over a 150 beta builds later and 2 years in the making, we’re super-pleased to introduce you to EasyBCD 2.0. It’s so incredibly overhauled and improved, so stuffed-to-the-brim with features, so much of a true one-click dual-boot experince, so customizable, so powerful, and so EASY that it took a lot of self-restraint to keep from calling it EasyBCD 10.0!

What’s new, you ask? We’ll get to it. But let’s just first give you the download link, because we know you just can’t wait to get your grubby, geeky paws on it ASAP:

Download EasyBCD 2.0.1 (1337 KiB)

(Yes, it really is 1337 kibibytes in size. And, no, we didn’t do it on purpose. We’re just übercool that way!)

Our List of Highly-Anticipated Upcoming Games for OS X (2010)

For too long, computer gaming has been a strictly Windows-only business. But that’s slowly but surely changing, as signified by the recent availability of the popular Steam platform for Mac, and soon, Linux. But what’s really exciting is that big game producers aren’t just porting old games to OS X *cough* Quake 4, Halo 1, etc. *cough*, nor is the world of OS X gaming going to be limited to indie publishers and lame (though very much appreciated) games with graphics on-par with those from the 90s on other platforms.

We’ve compiled a list of our top highly-anticipated games for OS X, most of which are actually geared for simultaneous release on Windows and Mac, making it clear that Mac gamers will take a backseat no more. Honestly, we’re not going to bother ranking them or making this a “Top 10 Games for OS X this year” kind of article. This is just a geeky gamers’ list of games to look out for, on a Mac, soon. We’re not including games that were previously available on other platforms, because that’s just sad.

And, without further ado, here’s NeoSmart Technologies’ exclusive list of upcoming Mac OS X games, sorted by expected release date from the ones you can soonest get your grubby paws on to those you’ll have to not-so-patiently wait and pray for:

The ARM, the PPC, the x86, and the iPad…

Posted on by

Hot on the heels of the iPad release comes news that Apple has just (very likely) purchased another processor design firm (via EDN).  Intrinsity, the chip design company in question, is a designer of RISC-based CPUs and is rumored to have had something to do with the design of Apple’s new A4 processor. The A4 is Apple’s key ingredient for a smooth user experience in the much-hyped iPad.

Those keeping track of Apple’s purchases will remember that, almost exactly 2 years ago to the day, Apple bought California-based CPU designer PA Semiconductors. However, PA Semi specializes in PowerPC-based designs – a platform that Apple abandoned almost 5 years ago now. But Apple’s most recent acquisition is directly applicable to its current needs in the hardware market, and in particular, its forays into the ARM market. In the official iPad video, Apple engineers and executives discuss their need for a custom CPU in order to let them dictate where the ooomph and power will go, and to what purposes the transistors will be biased.

With all these buyouts and different chipsets in question, it’s easy to get confused. So what is the difference between the ARM, the PPC, and the x86, and where does it matter?

Make Old Java Applications Fully Snow Leopard Compatible

If you have a bunch of old Java applications lying around in your Mac’s /Applications folder, chances are, you’ll come across this message box when you attempt to run them on Snow Leopard:

To open JavaApplicationStub, you need to install Rosetta. Would you like to install it now?

To open JavaApplicationStub, you need to install Rosetta. Would you like to install it now?

Personally, I try my best to avoid legacy Mac OS apps and haven’t found the need to install Rosetta on OS X 10.6 Snow Leopard as of yet. Whether you have need of Rosetta for your other applications or not, there’s no reason you should be running your Java-based applications through the Rosetta environment — they’ll run just fine on native Intel Java on OS X… with just a little bit of a prod in the right direction.

Java applications are CPU agnostic (hence the “write once, run everywhere” Java motto). The Java applets you download and use can theoretically be run on any PC machine that supports Java; be it Intel, PPC, ARM, SPARC, or more. The native Java virtual machine will translate the “Java bytecode” into the equivalent machine assembly that your PC uses and understands, and therefore, Java code written for legacy Mac OS should run just fine on Snow Leopard

Does it GTK/QT/Win32 Really Matter for Chrome?

128px-GoogleChromeLogo.pngA recent article on OSNews highlights the changes expected to come in Google’s Chrome 2.0 for Windows and the progress being made on the Linux and OS X fronts for Google’s new browser.

In the article, Ben Goodger, lead Chrome UI developer, states

[Google avoids] cross platform UI toolkits because while they may offer what superficially appears to be a quick path to native looking UI on a variety of target platforms, once you go a bit deeper it turns out to be a bit more problematic.” [... Your applications end up] speaking with a foreign accent.

But there’s something we’re not getting here. Obviously given enough brilliant programmers and a good team lead to keep the different codebases in sync, going with native APIs is the better approach. But the reasons Goodger is offering aren’t very convincing.

OS X Snow Leopard to Use ULE Scheduler?

Posted on by

snow-leopard

Ever since Steve Jobs first unveiled the next version of OS X, dubbed “Snow Leopard,” the internet has been abuzz with excitement and wondering about the supposed “evolutionary” qualities of OS X 10.6. One of the most-hyped improvements is the promised revamp of the SMP capabilities of OS X, with a “breakthrough” in SMP performance.

The codename for the technology behind the SMP improvements in OS X Snow Leopard has been named “Grand Central,” which Apple describes best:

“Grand Central,” a new set of technologies built into Snow Leopard, brings unrivaled support for multicore systems to Mac OS X. More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.

Our guess is that these SMP “breakthroughs” are going to be delivered in two blows:

  1. Improvements to the OS X kernel intended to boost multi-threading & multi-tasking performance and better-distribute the loads across multiple CPU cores more intelligently.
  2. Provide an SDK (perhaps as improvements to XCode) that allows developers to more-easily write multi-threaded code, handle forking, and provide load-balancing features on a per-core basis.
