Can't stop Thunderbolt display from flickering white lines after firmware update (Yosemite)
I am having serious issues after the Thunderbolt Display Firmware Update 1.2. Running Yosemite on MacBook Pro and I am now getting white lines that gradiate from the bottom to the top of my screen across multiple browsers, apps and even the finder window anytime I move my mouse. I cannot take a screenshot (it stops when I try) but I posted a video here:
http://youtu.be/3zOKL1JFp5M
It is impossible to work this way and after 20 minutes of watching my screen constantly refresh anytime I move my mouse I am feeling nauseous.
Is there anyway to UNINSTALL this firmware update? I was not having this kind of problem before. Every once in awhile I was finding my Thunderbolt display would not wake up after sleep and I thought the firmware update would fix that, not cause more, crazier problems. It is causing this gradiating line problem on my Thunderbolt display AND my MacBook Pro screen, which is even more bizarre.
I updated and no issues with my 2012 Mini so may be computer related. I believe once a firmware has been "burned" into the chip it cannot be redone.

M5035MFP displays Permanent Storage Write Failed after firmware update to 48.301.7
After updating the firmware to 48.301.7, I have two M5035MFP machines that are displaying "68 Permanent Storage Write Failed" error messages. The users can press Continue and printing will proceed normally for another 10-50 pages when the message will appear again. The NVRAM and HDD have been reset/intiliased and they have been powered off/on several times.
This is also occurring on two other different models (6040MFP/9040MFP) which also started showing up after a firmware update about the same time.
Could this be a failed update? How would I go about downgrading to a previous firmware version?Hi Rwelper,
I want to share with you this solution:
Please try first to reseat the Formatter/HDD and the memory DIMM and install the correcly then try:
First it is not adviced to downgrade the firmware at this step, you can try a cold reset and upgrade firmware again.
here, you need to remove the existent Firmware file on your PC and try to download it again from the HP Website, thus you can instaltly disable the firewalls and the antivirus and do this action.
NOTE: You can try a new upgrade firmware before you proceed with the Cold reset* of the printer.
Cold reset (Format disk also can be performed if this don't work): You can check the printer's manual to know how to perform it.
Please try an NVRAM init or Super NVRAM Init if this don't give a solution.
All these manipulations you can find in the printer's manual
Please note also that all these manipulations will delete all the current printer's configuration if it going to be working fine, so you will need to upgrade firmware and set your printer up again.
==> There is a need to delete files on the HDD / data on the DIMM, unplug and restart the printer.
The final solution is to replace the Formatter then the HDD if all these solutions don't bring a result.

I urgently need to know how I can connect 8 thunderbolt display, I was thinking with the new mac pro will come out, but I wonder if it is possible to connect an iMac to 4GB of graphics card, but suffers from the imac. thanks
I tightened all HD screws and it didn't help. With the machine running and side of the case off, I physically stopped both the video card fan and the front case fan with my finger for a couple seconds and the noise continued. I also took all hard drives out one by one and rebooted each time. Again, the noise continued until I took out the Mac HD in Bay 1, rebooted, and I had a very quiet, silent machine. The issue is the hard drive in bay 1 that shipped with the computer, it's without a doubt causing the hum/woosh sound. I still need to know if I can safely swap the Mac HD from bay 1 to bay 4 without any issues to the operating system. I would like to try that to see if it dampens the noise but I also want to make sure this swap won't screw up my machine at all.

When I record an audio track using Logic Pro X, there is a visible waveform which appears as I record. When I stop recording, the waveform disappears and becomes a straight line. It also disappears from the track edit window. But the sound is still there. How can I stop the waveform from disappearing? And can I do something to view it after it has disappeared? Anyone know the anser?
In Logic:
Preferences/Audio Set Recording Delay to 0 <zero>
This should always be set to zero unless a specific set of circumstances exist and you're audio drivers do not report position correctly.
On occasion, usually when importing a Logic 9 project, Logic-X randomly changes this to a negative/positive number. It's actually a bug in Logic, as it should always display the waveform. -

How can I stop my iPhone from synching my contacts and groups lists twice?
How can I stop my iPhone from synching my contacts and groups lists twice....I am using iCloud but am not sure how correct this duplication.
Go into Settings>Mail, Contacts, Calendars. Is this happening at the bottom in the signature section, or in the header of the mail where your email address is? If it is the signature, then go to the Signature area of the Mail settings. If this is in the header, then go to the account in question and edit your account information to include your name instead of Johnny.

How can i stop internet media from flooding elements 6?
how can I stop elements 6 from constantly importing internet photos and flooding my memory?
PSE isn't importing photos off the internet, but it could be importing photos from your hard drive that are being placed there as you browse the internet.
It's likely that you've told PSE to import all new photos on your hard drive using the Watched Folders mechanism.
In the Organizer, go to File > Watch Folders...
See the list of folders PSE is currently watching.
Check the setting near the bottom of the dialog as to what PSE should do when it finds new images in the folders it is watching.
Make any necessary changes to have it do what you want it to do.
Cheers

Please tell us what model of Mac you really have. In the body of your post you refer to a Mac Pro, but your profile says you have a MacBook Pro and you've posted in the iMac forum. We need to know what you really have before we can offer any advice. We also need to know what "tried alot but it's not supporting" means.
