As nifty and drool-worthy as the 2011 MacBook Pro notebooks may be, there still may be issues to sort out.

Per MacFixIt, a number of owners have noted an issue wherein the machine will start up to the gray Apple logo screen without a progress indicator and freeze. Apple has also noted the issue, releasing a knowledge base article to help with the situation.

Apple Support Discussions forum user CoryCripita writes:
“So for the second time my Macbook Pro is stuck on the ****** gray screen and won’t boot. The first time this happened 2 days ago I HAD TO resort to Archive and install. The only thing that I can even think caused this was again the fact that I updated via Software Update then rebooted.”
One suggestion offered on the forum was to reset the PRAM. To do so, turn off your machine. While holding Command + Option + P + R, turn your Mac back on. Wait for the boot chime to ring three times and your machine will start normally.

Apple has released a knowledgebase article to address some causes of this problem. According to the article, the Mac booting to the gray logo screen “may happen if the computer starts up from the hard drive or from an external drive using the wrong version or build of the operating system.”

If this happens, reinstall the proper build of Mac OS X from your install DVDs that came with your Mac. Later versions of Mac OS X will also work, but the article notes that using a version of OS X that was released before the computer will likely cause this issue.

You can check and see which version of Mac OS X your machine is attempting to start from by booting your Mac in Verbose Mode. When starting up, hold Command + V. If a DOS-like white text on black screen pops up, you’ve done it correctly.

“If the computer has the wrong build of the OS installed, the startup process will stop. The following line of text will appear on the display: “Loading SystemLibraryCachescom.apple.kext.cachesstartupExtensions.mkext.””
Hold the power button to shut down and quit Verbose Mode. When you next power on your Mac it will start normally.

Here’s the thing with updates: they’re great and generally resolve problems and turn a disaster around.

Then there’s the other 10% for whom they make the sky fill with brimstone, the seas boil over and cause your cat to start waltzing across the living room floor with your terrier.

Per AppleInsider, Apple’s small Boot Camp update for the new 2011 Thunderbolt-equipped MacBook Pro models appears to be causing problems with adjusting screen brightness for some users.

While Apple said the update addresses issues that existed with system shutdowns and resolves problems with Japanese and korean keyboard, users on the official Apple Discussions page have reported that new issues were created with the update. Specifically, numerous Boot Camp users have reported since Thursday that the 3.2 update mistakenly disables the ability to control screen brightness in Windows.

“Clicking the brightness buttons (fn + F1) causes the little brightness icon to come up and move up or down, but the actual screen brightness won’t change and stays at 100%,” user pwhe23 wrote. “I don’t remember this happening before I upgraded.”

A number of other users chimed in on the thread, reporting similar results, even with a fresh install of Windows 7. User ckahn said they managed to address the problem by installing the 32-bit version of Windows 7, rather than the 64-bit operating system.

And user Polytonic found a “temporary workaround” by setting the brightness in Mac OS X, then rebooting to Windows. The Mac will apparently remember the brightness setting applied in Mac OS X and it will carry over to Windows upon the system reboot.

Per the cool cats at MacFixIt, Apple has released an update to the Boot Camp drivers for the latest MacBook Pro systems. This update addresses a couple of problems with Japanese and Korean keyboards in the system, and also fixes shutdown problems, according to the update’s download page. The update is specific for Windows 7, so if you are using an alternative version of Windows, this will not apply to you.

The update should be available for Boot Camp users via Apple’s Software Update utility, but it can also be downloaded and applied manually from the Boot Camp 3.2 Update web page. The update is 21.55MB in size.

If you’ve tried the update and noticed any changes, please let us know in the comments or feedback.

2011 MacBook Pro Turbo Boost problem may be larger issue than originally thought

The good news is that the new 2011 MacBook Pro notebooks are out and they are generally considered speedy and awesome.

The bad news is that Apple may have been aware for some time of the problem of new MacBook Pros crashing under heavy loads. According PC Pro magazine, Apple appears to have deliberately turned off Turbo Boost for the top-end 13″ model (with a dual-core 2.7 GHz Intel Core i7-2620M processor) when running Windows under Boot Camp.

PC Pro originally thought that Turbo Boost had been disabled under OS X as well, but then tests performed by AnandTech showed that the feature was only disabled under Windows. “We first noticed a problem when the benchmarks finished five full runs and the results popped up on screen: the times taken to complete several of the most intensive tests were rising with each run” says PC Pro. “This would suggest an overheating problem, so we ran a temperature monitor to find out how hot this Sandy Bridge CPU was getting.”

In fact, the CPU was reaching around 93°C — almost 200°F. “93°C is not necessarily too high for a modern CPU, but it is the root cause of the bigger performance problem.” The magazine went on to state that it was sure the processor isn’t turning off Turbo Boost dynamically, since it didn’t work at all during their week of testing no matter what the CPU temperature was. Also, the cheaper model with the i5 processor did use Turbo Boost, as did the i7 model under OS X.

After measuring the underside temperature of the top-end model at 60°C — 140°F — they conclude that it might actually be a better deal to buy the cheaper 13-inch MacBook Pro. If Turbo Boost is disabled on the higher model, the lower-end version will actually run Windows faster than the more expensive MacBook Pro.

Stay tuned for additional details as they become available.

It’s not as specific a problem as you might like but it’s getting some attention.

Per MacRumors, a lengthy discussion thread on Apple’s discussion forum reveals an issue that some new 2011 MacBook Pro owners have been having with their new machines. A MacRumors discussion thread also mirrors some of the complaints.

Forum user lithast describes his situation:
“Received a new 15″ 2.2/6750M MBP last week and have been having some issues with the machine locking up under load.

For example if I boot up a VM using Fusion the temperature will spike up above 90 degrees and the machine will lock up most of the time. The machine appears locked (cannot move the mouse at all and keyboard is unresponsive). I can SSH into the machine still and it still is running however. This is one example but it will freeze under a number of circumstances where the CPU/GPU load is very high (rendering, DJ Software, compiling so far in my travels).”

There’s been speculation that the issue is related to the graphics driver or power management, and it seems the issue is reliably reproducible. A wiki has been organized to document the issue. Apple is reportedly aware of the issue, but no reliable solution has been provided.

As nifty as the 2011 MacBook Pro notebooks are, there may be some debugging that needs to be done.

Per AppleInsider, a number of early 2011 MacBook Pro owners report being unable to connect devices or maintain connections through iTunes Home Sharing.

A support thread in Apple’s Discussion forums has received over 200 posts from owners of Apple’s latest MacBook Pros reporting issues with iTunes Home Sharing. Several readers have also contacted AppleInsider regarding the issue.

“This is turning out to be a bigger problem than I thought with many people giving up and returning their new MBP 2011 due to this conflict. Apple has yet to find a fix but it has been widely documented via phone through AppleCare and through many Apple retail stores,” wrote one reader.

According to forum user ‘themacbear,’ the new MacBook Pro was able to stream to a second-generation Apple TV at first, but then the Apple TV reported being unable to connect or would display the error message “There are no movies in this library.”

In March, Apple released iOS 4.3 with new Home Sharing features. The Mac maker also issued iTunes 10.2 and then iTunes 10.2.1 to add compatibility with iOS 4.3 and Home Sharing. In spite of the updates, a number of users continue to report being unable to connect or maintain connections with iOS devices on their early 2011 MacBook Pros.

Recent improvements to the Home Sharing feature expand iTunes library sharing from just between Macs, PCs and Apple TVs to include mobile devices such as iPods, iPhones and iPads. When working properly, Home Sharing in iOS 4.3 allows an unlimited number of iOS devices to access content over Wi-Fi.

Though early 2011 MacBook Pros appear to be having the most trouble with Home Sharing, owners of older machines have also reported problems with the feature in a support thread for Home Sharing in iOS 4.3 that has reached 60 posts.

Stay tuned for additional details as they become available and if you’ve seen this issue on your end, please let us know.

Apple includes SSD Trim support for 2011 MacBook Pro notebooks under Mac OS X 10.6.6

The future is solid state hard drives.

Which isn’t bad, as they’re pretty nifty.

Per AppleInsider, the 2011 MacBook Pro models are shipping with Mac OS X 10.6.6 (build 10J3210), which supplies TRIM support for bundled Apple Solid State Drives, enabling extended performance of the fast new devices via background maintenance.

The change comes a bit ahead of schedule as it had been previously reported that Mac OS X 10.7 Lion would incorporate support for the TRIM command, which helps the operating system coordinate the maintenance of unused memory cells on the new SSD devices, preserving long term performance.

While the new notebooks appear to run the same Mac OS X Snow Leopard 10.6.6 version, the newer build (10J3210 versus 10J567, the newest build of Mac OS X 10.6.6 available for download from Software Update by other Macs) includes and automatically activates TRIM Support, as noted in System Profiler.

Apple will likely roll out support for the new feature in an upcoming new build of Snow Leopard. The feature reportedly only supports Apple-bundled SSD volumes, but this may change as well.

Stay tuned for additional changes as they become available and if you have any feedback as to your new 2011, Thunderbolt-equipped MacBook Pro, please let us know what you think in the comments.

Apple’s first build-to-order units for its 2011 MacBook Pro notebooks began shipping, the company promising delivery by next Thursday.

Per AppleInsider, Apple began dispatching these shipments from its Far Eastern manufacturing facilities to Fed-Ex’s Shanghai, China-based shipping hub where they’ll be mailed via air fright this weekend to the courier’s stateside hubs for delivery to customers early next week.

Apple is currently promising delivery by Thursday the 3rd through its own order status system, while FedEx is a bit more ambitious, promising delivery by 10:30 am local time on Wednesday the 2nd for this particular order.

It should be noted that the custom configured MacBook Pro shown in the order below was shipped via Apple’s US$18 2-3 day shipping method, as opposed to its standard free shipping method. This particular notebook was upgraded with a 256GB SSD drive and 8GB of memory.

Meanwhile, several of Apple’s larger authorized resellers are already reflecting stock of the company’s five standard retail configurations for the MacBook Pro. And a handful are offering considerable early discounts of up to US$150 on the new models.

Stay tuned for additional details as they become available.

Per a recent Apple support note released Friday, the company’s new MacBook Pro models and the recently refreshed MacBook Air won’t support Windows XP and Windows Vista.

Note: Windows XP and Vista drivers are not supplied for these computers and are not supported.

According to the Apple Core, the note states that Book Camp will support 32- and 64-bit versions of Windows 7 Home Premium, Windows 7 Professional, or Windows 7 Ultimate. If you’re running Window XP or Vista on an older Mac and are moving up to one the new notebooks, then you will have to put a Windows upgrade into your budget.

Window 7 running on Boot Camp requires:

-An optical drive (MacBook Air computers require an external optical disc drive to install Windows 7).

-A blank CD or USB storage device to contain the Windows Drivers created by the Boot Camp Assistant.

-For 32-bit versions of Windows, at least 16 GB of free space.

-For 64-bit versions of Windows, at least 20 GB of free space.

-Boot Camp Assistant, which is pre-installed in /Applications/Utilities/

-An authentic, 32-bit or 64-bit Microsoft Windows 7 Home Premium, Professional, or Ultimate disc.

Stay tuned for additional details and if you have a new early 2011 MacBook Pro notebook and have had any experience with Boot Camp, please let us know in the comments.

iFixit performs full teardown of early 2011 MacBook Pro, finds interesting new components

It’s been all of a day since the release of Apple’s new Thunderbolt-equipped MacBook Pro noteboooks, but already the cool cats at iFixit have performed a full teardown of the new models.

Per the report, the guys found that the controller for Thunderbolt is the fourth largest chip on the logic board, after the CPU, GPU and logic board controller.

“We believe the chip’s footprint is a testament to the potential of this port,” they said.

iFixit ranked the new 2011 MacBook Pro a 7 out of 10 on its reparability scale. It noted that the new version allows for the battery to be disconnected without removing it from the laptop.

The addition of a “spudger” makes disconnecting the battery easier.

“It’s a nice design choice since you *should* remove all power before performing any repairs,” they said. “The unibody design also allows for easy access to most of the other components, so it won’t be terribly hard to replace things on the machine. The only tricky repair is LCD replacement, which could easily result in shattering the front glass panel.”

Other noteworthy details from the teardown:
- You can chain up to six Thunderbolt devices. In comparison, FireWire supports 63 devices and USB supports up to 127 devices.

- The lower case is secured by Phillips #00 screws, while the battery is secured by Tri-Wing screws, just like the predecessor. There were no Pentalobe screws inside or outside.

- The new MacBook Pro has the same 77.5 watt-hour battery as the earlier model, but Apple has decreased their run-time estimate from 8-9 hours to 7 hours, likely due to more stringent testing.

- The Thunderbolt controller is the fourth-largest chip in the new MacBook Pro.

- iFixit said they’re concerned about Apple’s quality control, as they found a stripped screw holding the subwoofer enclosure in place, and an unlocked ZIF socket connecting the IR sensor.

- RAM has been upgraded to PC3-10600. That’s the same RAM used in the 2010 revision of the 21.5″ and 27″ iMacs, but faster than earlier MacBook Pros.

- The wireless card received a make-over and now includes four antennas instead of three. Wireless connectivity is provided by a Broadcom BCM4331 “wireless solution.”

- The wireless card bracket is aluminum, rather than the plastic found in earlier MacBook Pro revisions. The change was likely made for thermal reasons, as a pink thermal pad is visible and used to transfer heat from the Broadcom chip to the aluminum bracket.

The logic board features four primary chips:
- Intel i7 Quad-Core Processor
- AMD Radeon HD 6490M GPU
- Intel BD82HM65 Platform Controller Hub
- Intel L051NB32 EFL (which seems to be the Thunderbolt port controller)

The teardown uncovered a great deal of thermal paste on the CPU and GPU when the main heat sink was removed. The excess paste may cause overheating issues down the road, iFixit said.

The new 15-inch MacBook Pro is still designated Model A1286. Apple has been using that same model number since October 2008.
