Better solution than PARAM reset to keep Thunderbolt Port properly working.

I have a MBP 17" (late 2011),
To its Thunderbolt Port I have connected my Samsung T260 Display alternately with a KANEX 'Thunderbolt to eSATA/USB3.0' Adapter.
But this always needs a PARAM reset after having the Display intermediately connected, else the ANKER 7xUSB3.0 Hub connected to the KANEX Adapter wouldn't be recognized correctly.
Is there a better solution available for selective resetting the Thunderbolt Port, without restarting the system?
Many Thanks for support.

Update: I obtained a new replacement MiniDisplayPort-to-HDMI cable, and both displays are working fine now. However — and this is what's weird — the fix was not completely immediate! At first, all the resolution modes (including 1080p) began working again, but I was still seeing ghost images of moved or closed windows on the screen! After a day or so, those went away. What could possibly explain the temporary persistence of the ghost images even with a new cable?

Need better solution than FCPX for audio cleaning

Hi, I have a track for a wedding with a lot of background noise. The settings to improve audio on FCPX are not helping much. What's the bets solution to improve voice and reduce background noise?
Thanks

If Audacity or STP don't handle it for you, seriously consider giving ScreenFlow a try. ScreenFlow has about the best noise reduction I've ever heard from any app I've ever used. You can load the audio (or video+audio) up in SF (create a New Document from the File menu), drag and drop your media into the Media panel, then drag it to the timeline; select the audio track, go to the audio panel (speaker icon) and select: Filter: Remove Background Noise (accept the default setting of 80%) -- that's usually all there is to it! There's a free trial available (http://www.telestream.net/screenflow/overview.htm) — it's fully functional except that it watermarks the video output. It will export AIFF audio (LinearPCM 48kHz) and you can export audio only.

IMac Thunderbolt ports stopped working

I have a late 2012 iMac 27". Both Thunderbolt ports no longer work.
Have tried an external monitor and hard drive. Nothing happens. Both work on another iMac.
Reset PRAM (left cmd+option+p+r), but nothing changed.

Mac mini thunderbolt port stop working

Good night.
First, I apologize for my English.
I have a mac mini (2011 model). Two days ago there was a power outage and the mac shut down. After turning it on, it failed to recognize my TV connected through the Thunderbolt port (with a adapter THUNDERBOLT -> HDMI).
When I disconnect and connect the adapter into the thunderbolt output, the screen flashes (as if he had recognized the second monitor). However, the monitor does not work.
Some Details:
1) In the monitor settings, only the main, connected by HDMI is detected;
2) On the "System Information" screen, the "Thunderbolt" item appears to state “no device connected";
3) I've done the reset PRAM / SMC.
Can anyone help me? Does my thunderbolt output fried?
Thank you,
Mateus.

I would try a different HDMI cable and then a different Thunderbolt/MiniDisplay Port to HDMI adapter.

Panic, now both Thunderbolt ports not working

I've read about PRAM and SMC resets, performed those actions but my thunderbolt ports with a TB to VGA adapter still do no work.
A few days ago I had a kernal panic but I didn't pay much attention as the MBP had been up for a week or usage. Then today I was preparing to use my adapter for a corporate event, and about 1 hour before, teh screen went grey with the panic screen.
Now both bothers do not work when I plug the TB to VGA adapter in. I can use that adapter in another MBP just fine. Seems to be just this machine.
What info can I post to gain assistance in isolating this problem?

Thunderbolt port not working in new Windows 8.1 32 bit install

I have a new HP Zbook 15 G2 that came with 64 bit operating systems for both Windows 8 and 7. I chose to install the windows 7 version, and the thunderbolt port is recognized properly and works fine. Howver due to the need for video capture in a 32 bit system, I chose to install a new windows 8.1 32 bit system on a new ssd. The install went great and everything is updated and working except the thunderbolt port. I have searched for a compatible driver, but I cannot find one. Is there a way to get this thunderbolt port working in this os?

I had a similar issue after upgrading my windows 8 os to 8.1. The volume bar would move, but the actual volume coming out did not change. Downloading the latest windows 8.1 audio driver from Lenovo fixed it for me.

Thunderbolt to Gigabit Ethernet Adapter or Thunderbolt port stopped working

Hey problem if anyone can help:
I use a Thunderbolt to Gigabit Ethernet Adapter, and all of a sudden it stopped working to connect to the internet on my Macbook Air (MacBook Air (11-inch, Early 2014 with OS X Yosemite 10.10.1 (14B25)). In my system information it says it is connected even when not, see below:
Thunderbolt to Gigabit Ethernet Adapter:
Vendor Name: Apple Inc.
Device Name: Thunderbolt to Gigabit Ethernet Adapter
Vendor ID: 0x1
Device ID: 0x8003
Device Revision: 0x1
UID: 0x0001000202DD0A30
Apple Serial Number: DTN4263048VDWKHBQ
Route String: 1
Firmware Version: 5.5
Port (Upstream):
Status: Device connected
Link Status: 0x2
Speed: Up to 10 Gb/s x1
Port Micro Firmware Version: 0.0.8
Can anyone help me figure out what the issue is? Is it the Adapter, the Thunderbolt port itself? A gremlin? Thanks!

Which model MacBook Pro do you have? Does it have a Thunderbolt port? If so the TB->Ethernet adapter MAY work (although it's specifically designed for those MacBook models that lack an Ethernet port).
The adapter would certainly be the cheapest way to go - if it works. Personally, I would rather have the Ethernet port on my MacBook Pro working, but this may be an expensive fix, I don't know. If I were you, I would at least take your computer to your local Apple Store/AASP and get a free diagnosis and estimate to repair your MBP. If it seems as if it's going to be too costly, then you may certainly try the adapter and see if it works.

Delete non-empty directory: better solution than traversal?

So far, I'm only able to delete a directory via File.delete() when I delete each single file in this directory and recursively in any subdirectories. I wonder if there is a better/easier way to delete non-empty directories?

Yes, it takes a fraction of a second. To be exact: about 0.3 seconds in our cases for each temporary directory with about 1.5 MB content and less than 100 files.
But during big reports with hundreds of pages, each pages producing several such temp directories, this deletion takes about 5-10 seconds for a full report. Now, we have several customers with several users generating reports all over the place and reducing processing time is of good value. 10 seconds less for reports the user is waiting for might not be a big deal for you but for our customers.
I read in some Linux forums that some file systems just remove the root directory out of some tree structure without recursing the whole tree. That's why deletion is so fast and "real deletion" (to not be able to undelete files) is slow. Unfortunately, we have Windows servers ...

Can you please recomend a better solution than this?

I use a servlet to send data from a form to a Mysql database.
The servlet code is the following.
When i submit the form i receive an Error 500 from Tomcat upon the 69th line of the code.
The code has as follows.
package mypackage;

Connection con = DriverManager.getConnection("jdbc:mysql://localhost/se?user=luser&password=Ztgtkpz2");
catch (ClassNotFoundException e) {
throw new UnavailableException("Couldn't load JdbcOdbcDriver");

pstmt.executeUpdate();

Can you please recomend a solution to my problem.
If i mange to overcome the bug do you have any suggestions upon connection pooling or anythink that will make it to run smoothly?
Thank you for your time.

Look where you try to populate the connection variable con:
try{
/* Loading the driver for the database */
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/se?user=luser&password=Ztgtkpz2");
Notice that you redeclared Connection con as a local variable.
try this instead:
try{
/* Loading the driver for the database */
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost/se?user=luser&password=Ztgtkpz2");

Thunderbolt port not working as dvi in New iMac, is there any fix for it?. I have a Samsung SyncMaster 2494 SW

Just bought the new iMac, also bought apple's mini dvi adapter, when connecting to Samsung SyncMaster 2494sw i get a snow kind of pattern and sometimes let me see apple desktop through it, i tried changing resolutions but nothing, is it a software issue?

Well my friend, after 3 1/2 agonizing hours at he apple store, those "genious" declare that iMac came with defective thunderbolt/dvi to extra monitor , not mine, ALL OF THE NEW iMACS!!!!, shame on apple man, i had to spend 300 extra dls buying a new monitor with hdmi input to solve this crap that apple just did, is not fear coming out with a new product that can handle something so simple. i wish i could report this issue to someone that hears it and make something about it since i do not think this is a minor issue since this new iMac main feature was the thunderbolt port

Is there a driver so that a Belkin Thunderbolt port can work on Bootcamp - Windows 7?

I purchased a Belkin thunderbolt dock/hub at the apple store. It works well on my Yosemite OS X 10.10 2012 MBP 15", but not so well on Bootcamp running W7.
The display via an TB to HDMI adaptor in the dock works, and the sound in and out works (some small issues here, but there eIS sound) but the USB device do not work. I hear that ethernet also does not work, but I am most interested in the USB iMAC keyboard and its hub, which does not.
I found several drivers that say they work but in the end they all cause a PC BSOD (Blue Screen of Death) and in the first case a corrupted Macintosh drive. Fortunately I was able to recover completely... I think..
Anyway I'm still looking for the appropriate driver.
Does anyone have a suggestion?
The drivers I tried are:
Driver_ASM106xv139whQl.7z
and
FLUSB3.0-3.5.108.0a
And another question. When I un installed and deleted the "bad' drivers from the windows system, the name of the driver is still shown in the device manager? Why would that be? I disabled it because if I uninstall it Windows tried to re install it.
Any help and advice is eagerly requested and accepted
Thanks
Barry

Thunderbolt ports not working properly on new MBPwR?

So I went to go transfer 130GB to my new computer with a thunderbolt cable and it says it was going to take 53 hours? What's the deal?

Click photo to enlarge
The M7 controls functions from a variety of discrete sensors including a gyroscope, an accelerometer, and a compass. The M7 chip has been identified as NXP LPC18A1, part of the LPC1800 series of NXP's ARMCortex-M3 based microcontrollers. The M7 is probably the culprit. Is it reprogrammable through a flash upgrade? It does have some EEPROM on the chip.
Apple do you have a plan to correct the problem?

My Thunderbolt ports on fritz

Greetings. I have a late 2012 iMac (27inch). The two thunderbolt ports have stopped working and I can't seem to get them to work. Trying to avoid lugging it to the Apple store. I have tried the SMC and PRAM reset in order three times as recommended in this discussion:iMac Thunderbolt ports stopped working. I have also done hardware diagnostics it says all is OK in hardware.
I can't seem to find any other proposed solutions out here. Does anyone have any suggestions?
Many thanks.

The technician scheduled via Apple Care provided on-site service as promised. It was confirmed that my Thunderbolt ports had fried and he replaced the logic board. All is working perfectly.
We were blown away by the efficiency and level of support and follow-up by Apple Care. This is so much different to support issues we've had in the past with companies such as HP. They really have their act together and I am relieved that I took out the three year care plan option when I purchased the iMac. It's already paid for itself, as all servicing and repairs were covered by the plan.

Calendar on iOS 7. Anyone noticed that when you enter text into the "notes section" of a day, the text disappears behind the keyboard rather than scrolling down to keep pace with text entry ? Looks like an 7 glitch to me ?

Doesn't do that for me. Try resetting the phone

I have backed my iTunes with over 10,000 songs on a hard drive and than i reset my computer to factory settings, when i put it back on my macbook pro only 2030 were able to be downloaded back to the same computer

i have backed my iTunes with over 10,000 songs on a hard drive and than i reset my computer to factory settings because my email was hacked, when i downloaded the music back to my macbook pro only 2030 were able to be downloaded . how can i download all my music back?
michel p.

I usually err on the sideof caution when someone says "downloaded" and take it to mean anything fro actually downloaded, to copies, to imported, to moved (frolder to folder), but even if they were "downloaded"... if the old email was hacked, and subseuqently closed out, that leaves the downloaded files "orphaned" if you will, belonging to the old ID. So, while they may be on the HD, they're inaccessible now.
One of the biggest reasons I NEVER keep anything in my library with DRM employed in it. I bought it. I own it. I'm not going to get locked out of it.

Better solution than PARAM reset to keep Thunderbolt Port properly working.
