I saw in a number of posts that 10.8.3 would fix wake on lan issues. I am very disappointed to report that it did not fix it. Once the iMac goes to sleep there is no file sharing or screen sharing from the mac book pro and there is no wifi sync from iOS devices unless you physically go wake the computer up. This just sucks.
I'm much rather dual boot to Ubuntu than Windows 8. I'd like to try out Ubuntu. But as far as I can tell, there's no easy way to do that.![]()
I have yet to see a totally trouble-free SATA 6Gb/s SSD. No matter what SSD you pick, there seems to be some issues. All 6Gb/s SandForce based SSDs seem to be having a share of issues which look like firmware related.
WebKit was a life saver for me on my old 2008 MBP. Recently Safari has been good enough to skip the variability in WebKit. Personally frame rates aren't all that important to me as I've never been a big gamer.Safari seems... snappier on sites like The Verge. I used to get about 25fps with 6.0.2 and now I'm getting 35-36fps on my 2011 MBA i5/4GB. It's nowhere near as quick as Webkit nightly's 50+ but it's a start.
I'll probably have to take the plunge on a rMBP 2014 to be honest -- I love this little guy but it's just not as speedy as I thought it'd be in 2013. Also, the lack of USB 3.0 sucks, I didn't think Apple would adopt it so soon.

Great, I installed Windows 7 yesterday specifically because Windows 8 wasn't officially supported.
Is anyone watch the presentation of the Galaxy IV? WTF? They have created a cheesy broadway play with actors, tap-dancing kids and more cheesiness to announce the phone. Are you kidding me?
Does this fix the HDMI issue on late 2012 mac mini's??????
As for why...long story thats further explained here
"the intent of storage-based data deduplication is to inspect large volumes of data and identify large sections – such as entire files or large sections of files – that are identical, in order to store only one copy of it."
This happens without any regard to whether data is compressible or not.
If you have two matching sets of data, be they incompressible or not, they would be subject to deduplicatioin. It would merely require mapping to the same LBA addresses.
For instance, if you have two files that consist of largely incompressible data, but they are still carbon copies of each, they are still subject to data deduplication.
SandForce presumably uses some sort of differential information update. When a block is modified, you find the difference between the old data and the new data. If the difference is small, you can just encode it over a smaller number of bits in the flash page. If you do the difference encoding, you cannot gc the old data unless you reassemble and rewrite the new data to a different location.
Difference encoding requires more time (extra read, processing, etc). So, you must not do it when the write buffer is close to full. You can always choose whether or not you do differential encoding.
It is definitely not deduplication. You can think of it as compression.
A while back my prof and some of my labmates tried to guess their "DuraWrite" (*rolls eyes*) technology and this is the best guess have come up with. We didn't have the resources to reverse engineer their drive. We only surveyed published literature (papers, patents, presentations).
Oh, and here's their patent: http://www.google.com/patents/US20120054415
With most SSDs, formatting the drive will fully restore it's performance, so the behavior we're seeing here is not completely normal.
Remember that even if TRIM is active at all times, sending a TRIM command to the controller does not mean the data will be erased immediately. If you're constantly writing to the SSD, the controller may not have time to do garbage collection in real time and hence the SSD may be pushed to a very fragmented state as in our test where, as we can see, TRIM doesn't work perfectly.
I know that our test may not translate to real world in most cases, but it's still a possible scenario if the drive is hammered enough.
I think this was fixed with a firmware update sometime earlier this month
Interesting, the comments debunk much of what the original article states regarding SandForce controllers. I believe one individual, JellyRoll, discusses the issue:
Which was posited by user FunnyTrace:
It seems SandForce uses data differencing.
The author states in response:
It appears these "tests" are on the extreme of the bell curve, something many (if at all) would not experience in real world scenarios. As far as SandForce seems to be concerned, it has its own methods in handling data that TRIM seems to conflict with, making TRIM unnecessary. All good in my book![]()
this update fix the WIFI drop issues with the 2007 and 2008 MBPs? If so i will update if not I am staying with X.7.5
Not in a minor update.Last I knew OpenCL still wasn't supported on Intel GPU's, is this still the case?
Probably spotlight. Wait a few hours.Anyone else having much higher idle temperatures after updating?
That was for the HDMI screen blanking out. The problem now is that HDMI monitors are showing up as TV's instead of monitors and the whites are all blown out and the colors are all way off even after calibration.
Can't speak much to it personally myself since i don't own a Sandforce drive. Was just repeating the general trend on the forums which is if you have Sandforce you don't need TRIM and enabling it might hamper your drives performance.
Experience will of course differ even more so and Sandforce firmwares mature.
*shrug*
WOW! I can see the difference in my late 2012 mac mini. it's faster than before
Now I'm going to install WIN8 via boot camp
