Apple Hardware Test, What is the Extended Test?

Hi. Using the Apple Hardware Test under disc 2 of the iMac's (late 2009) there's a checkbox for an extended test but it takes significantly longer compared to around 3 minutes only with a normal test. What does the extended test that the normal test have? Does it test more parts in the iMac?
Is there a third-party that's better than Apple Hardware Test that can test every bit of hardware in the iMac including it's power supply, internal battery charge, transistors, capacitors (if there are capacitors that are about to burst or are not delivering the proper voltage or current), if every pixek in the LCD is good, if the speakers are not torn, etc.
Gbu.

The extended AHT does a much more extensive set of tests on your RAM.
An alternative memory tester is Memtest which is a terminal command with Rember being a GUI layer for memtest.
There's also the diglloyd tools memorytester but it is not free.
AHT does video testing but I am not sure how extensive it is. And I'm pretty sure no utility exists to do component-level validation. Does such stuff like that exist for any piece of electronic equipment (TVs, radios)? That's what volt meters are for and possible test points on the pc boards.
I should add there are utilities like iStat Menus which are capable of displaying temperatures, volts, amps, watts of all many components of the hardware. But they just display the info, they aren't testing the stuff. It's up to the person looking at that info to decide if something is too hot, drawing too much current, etc.

3rd gen iPod Nano will not sync with latest version of iTunes. It passes the connectivity test but not the sync test under diagnostics. Worked fine on old Windows 7 laptop but not new one. From Control Panel it shows up as an Apple iPod USB Device...

Never mind, I think. I think I figured it out. There was 1 song (out of > 900!) that somehow had been purchased with the other ID - I have no idea how. Once I deleted that song, it stopped asking.
There may be something with the newest iTunes version too. I didn't think in older versions that the "On this iPod" list of songs was greyed out. But at least it syncs ok.

"jdbc:mysql:///test" - "jdbc:mysql:test" what is the difference

"jdbc:mysql:///test" -> "jdbc:mysql:test" what is the difference:
I used both of them in my url but only "jdbc:mysql:///test" worked only
what is the difference what /// means?

JDBC URLs have the format
jdbc:<subprotocol>://<data source identifier>
jdbc indicates a JDBC data source. subprotocol identifies which JDBC Driver to use.
For com.mysql.jdbc.Driver and localhost server, database name as 'test':
it's jdbc:mysql://localhost/test
or jdbc:mysql://127.0.0.1:3306/test
you would select another server and database name.
For sun.jdbc.odbc.JdbcOdbcDriver with MS Access or SQLServer database, it's jdbc:odbc:DSNname

Although not illegal, Apple discourages a user from modifying the iPhone OS in any manner, including "jailbreaking". Apple feels so strongly about this that discussing methods to assist a user trying to either jailbreak or "unjailbreak" an iPhone are prohibited.

Create Unit Test Vectors From The Unit Test Configuration Window

I have recently been using more test vectors in the unit test framework.
The principle works well but if you are in a unit test and decide you need a test vector you must:
Close the unit test configuration
Create a test vector
Set up your vector (entering values and data types, which is much easier if you could see the actual unit test case)
Close the vector configuration window
Open the unit test configuration
Assign the new vector file to the unit test
Now you can assign vectors to test inputs
This seems convoluted and forces unnecessary context switchs.
I propose that at a minimum, you should be able to create a new vector file and launch it's configuration without leaving the unit test configuration window. I suspect that the whole process could be streamlined even further though.

Generating 2 test reports for the same test - XML and HTML

Hi All,
I have a special test requirement.
Need to generate 2 test reports for the same test. One in HTML and the other in XML format.
Is there any direct method for that?
How it can be implemented?
Thanks in advance.
SajK

Hi SajK,
To accomplish this task, you will need to modify the process model. For example, if you are using the sequential process model, you can concentrate on the TestReport sequence call and the various report related steps in the Single Pass and Test UUTs sequences.
The TestReport sequence (also a callback) relies on Parameters.ReportOptions.Format to decide which of the following sequences to use when generating the report:
<TestStand>\Components\NI\Models\TestStandModels\reportgen_txt.seq
<TestStand>\Components\NI\Models\TestStandModels\reportgen_html.seq
<TestStand>\Components\NI\Models\TestStandModels\reportgen_xml.seq
In your case, instead of choosing one of the sequences, you could hard code it to use both the html and xml sequences. Be aware that for this to work, you must also modify and/or duplicate most of the report related steps in the Single Pass and Test UUTs sequences. For instance, the Set Report Format step becomes unnecessary since you are hard-coding the report format. On the other hand, the Write UUT Report step needs to be duplicated, one step to write to an html file location, and another to write to the xml file location.
Please note that modifying the process mode in this way will deprecate some of the settings in the report options dialog box (such as the report format). For more information on TestStand report generation, please refer to the following DevZone article:

Welcome to the Apple Community.
Netflix recommend a minimum connection speed of 0.5 Mbps, however at that speed many of the other features of the Apple TV will be painfully slow.

The warranty is only valid in the country where you bought the phone. To get it serviced by Apple, you'll have to bring it back personally, Apple does not ship internationally.
If you can't bring it back to Apple in Canada, your only other chance is to search for a 3rd party repair shop. An Authorized Apple Service Provider in your country will not service the phone, sorry.

I want to create a movie in iMovie 10 and watch in on Apple TV. What is the best work flow to save hard drive space?

I want to create a movie in iMovie 10 and watch in on Apple TV. What is the best work flow to save hard drive space?

Jim,
Thanks for the advice. I have avoided iMovie Theater because that would soon use all of my free iCloud allowance (although that could be an option). I have been sharing to iTunes at 720p thinking that my picture using Apple TV would be better than Large. I see now that I could use about 30% less hard drive space by using Large instead. Do you think I will experience an annoying difference in picture quality?

My MacBook Air can't get past the gray screen with the apple logo. What's the fix?

My MacBook Air can't get past the gray screen with the Apple logo, so I can't login. Does anyone know the fix for this?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, reboot as usual (i.e., not in safe mode.) If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see above for instructions.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Multiple Numeric Limit Test - Accessing only the failed tests

I would to access only the failed tests in a multiple numeric limit test. The specific information I want to access is the measurement value, low limit, high limit, and comparator type. I need to access these pieces of information during runtime from a Message Popup, therefore i have to use the Message Expression field in the "Text and Buttons" tab of the Message Popup step to access this information.
[DL]

Hi,
PostStepFailureCallback is the one you want to start with. The only difference is where you get the data from the Step.Results.
For the Limits etc you will need to look in the Measurement property. Also, beware that you are dealing with an array of data.

X 86 hardware components - what is the optimal choice ?

hello
If I have to assemble a desktop with the purpose of installing solaris 10, what is the hardware that I need to buy ? The hardware list is a little difficult to understand because it does not specify a processor.
i want to use AMD / Intel processor, preferably dual core, what model numbers are most suitable for solaris 10 trouble free installation ?
What are the motherboards that support that processor ?
Do I have to be choosy about the harddrive ?
Does Solaris 10 require a specific type of RAM ?
Does it require a specific type of DVD+ R/W drive ?
It is not meant to be a mutliple o/s system. It is meant to be a solaris 10 only desktop, with minimal applications such as brwosing, email and star office...
Can the forum guide me on this ?

....it really doesn't provide me with info as to what is the optimal size/resolution of images to import, ...
I did, I think:
optimal in terms of 'fit' for a fullHD project is 1920x1080
optimal in terms of 'fit' for a 720p project is 1280x720
optimal in terms of 'fit' for a SDef project (final delivery DVD) is 720x480
optimal for a project with maximum wide Ken Burns panning is 10.000x6.000 (=KB allows a max factor of 5x)
optimal in terms of compression is as little compression on import as possible - a .raw photo file converted to .tiff or .png with some hilarious MBs of data
optimal in terms of handy is a 2k res photo as jpg with 2-5Mbs (just a rule of thumb)
optimal in terms of processing in iMovie is 8bit compression, optimal in terms of quality is 10-12bit compression (no idea wether iM supports that)...
=> there is no SINGLE answer because there are several 'optimums' ....
the resolution should be close to your videos res.
if you add Ken Burns, multiply
doesn't care for dpi - that is for print only
avoid CMYK codecs, video is RGB only
iMovie supports alpha only in png
avoid too much compression BEFORE import - lots of MB is good. Lots of jpg to jpg to jpg generations is not good.
and so on, and so on........
