All USB stops working after restarting iMac, please help!

I am having a serious problem with my iMac and i'm at a loss of what to do. I have a 24" imac with 10.5.6 and about a week or two ago I restarted my computer only to find that none of my USB ports were working. I thought it was a fluke so i just restarted again, only to find out that they still wernt working. I was forced to do a restore because I couldn't find a fix so I booted up from my leopard disc and did a restore from my time machine backup. I thought all was well and good until i restarted again yesterday. The same exact thing happened so I did another restore. Well, I just needed to restart my computer again and what do you know, my USB stopped working again! I have repaired permissions, done the apple hardware test, reset the PRAM, and verified the disc to see if there was anything wrong with it. I am at a total loss on what to do and Im really not looking forward to doing another restore only to have it do the exact same thing. Please help!

If you haven't tried this, try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US
When you booted from the restore disk, did you run Disk Utility to check the hard disk for errors?
If not... make sure and disconnect anything connected to the USB ports first,
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
Also, click the Apple logo top left in your Desktop, click: About This Mac, then click: More Info
That will launch your System Profiler. Under Contents on the left, click: USB and make sure your USB information is there.

Yoga 13 touch screen stopped working after update KB3000850, please help!

Hi, my Yoga 13 touch screen has been working fine until yesterday. The laptop came with Windows 8, and last year I upgraded to Windows 8.1 without issue. Yesterday, I installed optional update KB3000850 from Windows Update, and immediately the touch screen stopped working. I have tried the following methods, all without success:
* Uninstall KB3000850 from Windows Update
* Use Windows Restore to restore to the point before yesterday
* Re-install Intel Chipset Driver from Lenovo official driver page
* In Device Manager, uncheck all the "allow system to turn off to save power" options for the USB input devices under Human Interface Devices then restart
* Two-button shutdown and restart
* Install Lenovo Driver Manager and let it check for new drivers
* Download Cando multi touch panel driver (Note: I could not install the driver because all I got was a .cab file which does not allow me to install)
As of now my touch screen is still not working. Computer Information page from Settings shows that there is no touch or pen device for my screen.
Can anybody help me with this? Thanks!

Very true, this has been a known problem since the first day Lenovo released the Yoga 13.
I need to send Lenovo a bill for my time spent rebooting. So far i am on my 8th reboot. In the past, around 5 reboots after winddows update would work. This time... who knows.
Of course it always happens when you have a deadline.
Please post back if you have found a better soultion than system restore.
Thanks for posting this issue. More users need to bring this to Lenovo's attention.

Photo shop elements stopped working after automatic download, please help?

Bar appeared as I was working on a photo. Downloaded something on my elements program. now it does not work?

Hi,
I can't think what would require a download. Occasionally some of the special effects need to be downloaded when you use them for the first time but you appear to not be trying anything new - "you've done it hundreds of times".
Probably the first thing to try is to reset the preferences.
Hold down the Ctrl, Alt and Shift key as you launch the editor and hold them down until you get the message about resetting the preferences - which you do.
If you have changed any of the preferences, like allow floating documents, you will have to set them again.
I don't think the backup should have caused this problem.
Have you used it successfully since the backup and before the failure - or was this the first edit of the day?

I have the same problem when I updated to OS X 10.10 I lost both my USB ports as far as they will not recognize anything that I plug into them. The power part of the USB seams to work since it will recharge my Striiv Touch but nothing shows up when you connect anything to the ports.
I have tried a number of things from rebooting, trying other usb devices that work on other systems with no problems but will not work on my Macbook Pro.
Any Help out there?

[SOLVED] USB stop work after suspend (only right ports!!!)

Hi,
It drives me crazy!
I recently installed Arch on my new laptop SAMSUNG NP900X4C that have 3 USB ports, one in the left side and two in the right side . When I boot the system (or reboot) all USB ports works fine, but after system suspend like close lid, only the left port go back work. dmesg shows nothing when I plug a pendrive in the any right USB ports, even less lsblk.
This is my dmesg out when I connect the pendrive in all ports after boot:

Nothing appears about the USB ports 2-2 and 2-1. Any ideia?!
I even tried to install laptop-mode-tools and set CONTROL_USB_AUTOSUSPEND=0 but didn't work

Oh crap! I am kid with his new toy...
After a lot of google it I read something about firmware control the wake up of USB 3.0 and when I entered in this laptop BIOS what I found?! This option disabled:
USB S3 Wake-up [Disable]
So, just enable it and all my USB ports go back to work after suspend. I don't understand the purpose of it disabled by default.
Anyway I am sorry for this newbie mistake.

My new imac has stopped working!!! PLEASE HELP ME!!

I turned my imac on this evening to find that after the grey apple screen, the 'Loading Mac OSX' screen comes on and then goes off and a black screen comes up.
On this black screen it says:

Hello! At this point the first thing to try is to boot from the install cd/dvd. With the disk inserted hold down the "c" key at startup. Once booted run diskutility repair disk. You'll have to navigate within the installer window. If you can't get the tray open hold down the bouse button and turn it off and back on to open the tray. Tom

Iphoto froze and now won't work after restarting... help

I uploaded pictures to my MacBook earlier today, and while editing them, iphoto froze. I restarted my laptop and when I opened iphoto, it comes up, but doesn't show anything and gives me the rainbow circle meaning its trying to load. I have restarted my laptop many times now to try to get it to work, and it does the same thing everytime.
I have a MacBook, 2.4 GHz Intel Core 2 Duo, Mac OS X Version 10.6.8. It normally works fine, till I was editing today. Please help!

What version of iPhoto? Assuming 09 or later:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
Regards

My iMac won't install updates after restart. Please help?

My iMac will restart to install updates, but after logging in again, nothing happens. Even if I click the Apple logo and go to "Software Update", it tells me it still has to install the updates and to restart again. Having to end up with nothing again. Help please? =(

Check /Library/Updates/ for folders with numbers. If there are any, open one and double-click the one with a dist extension. If that installs, then repeat with any others. If not, manually download the updates and then install them.

USB stops working after BIOS flash to ABCN74WW on new Z70-80

Hi,
I started with Windows 7 installation on my brand new Z70-80 which worked fine, USB 2.0 ports had been working.
After flash of BIOS to ABCN74WW USB ports are not working any longer. I already tried soft BIOS reset by unplugging power and battery and pressing the power button for 20 seconds. USB ports are still unaccessible after this, a USB stick flashes for a moment, mouse LED is on, but no laser and no operation at all. Same when I start brand new windows installation.
Are there known issues with this BIOS version ? Can I undo the BIOS flash ?
Kind Regards
Solved!

Internet sharing stopped working after restart

Hi,
I'm connected to internet via thunderbolt->rj-45 reduction. I need to share intenet connection to my iphone and ipad via wifi. It worked fine until I restarted mac. Now I can see mac is connected to internet and sharing is on. On my iphone/ipad I can see the wifi name - i'm even connected to this wifi - but when I want to browse some webpage, safari is loading forever (to timeout)..
The firewall doesn't matter, because it worked fine before restart and I didnt changed any settings.
I tryied to turn off and on the Internet sharing, change security settings, restart wifi DHCP settings but nothing worked.
I tryied to set static IP's on mac and iphone/ipad but it still the same issue - devices can connect but internet doesn't work (loading forever).
I have OSX Moutain Lion 10.8.4 - Macbook Pro with retina
Any ideas?
Thanks

My beloved Pinkie randomly stopped working &refuses to charge. please help!

I don't know whats going on. and its not the charger because it charges my brothers ipod. ne suggestions?

Result. My wifi is back working again.
After a number of evenings trawling through the support pages, I found a youtube clip from a chap taking his macbook apart and locating the airport adaptor and connecting cables.
The cable in question is located in the black plastic bar below the display and is a pain to get to. Apprently the most common cause of this issue is the cable becoming dislodged through an impromptu knock. I can see how this happened to me by travelling on the London Underground everyday with my mac in my shoulder bag.
Anyway, having seen the video, I bottled it and went to the genius bar obviously having seen the clip. I had a worst case scenario quote of £95.00, but a quote for a replacement cable and reseal being much less. I'm quite savvy but my mac is sacred and i'd rather the pros did it. Turned out to be £37.00 and my mac came back fixed and clean.... £37.00 for piece of mind is well worth it.
Here's the youtube clip but please don't take unnecessary risks. http://www.youtube.com/watch?v=UsSIUs7jzQc
Best of luck all.
